Instant access to electronic component datasheets — specs, pinouts, package info, and more — extracted from manufacturer PDFs. No uploads needed.

SheetsData extracts and structures data from thousands of electronic component datasheets so AI agents can look up any part's specifications in seconds. Instead of downloading PDFs and parsing tables manually, just pass a manufacturer part number (MPN) and get back structured electrical characteristics, pin configurations, absolute maximum ratings, and more.

What you can do

  • Find components — Search across JLCPCB, Mouser, and DigiKey by part number or keyword, with real-time pricing and stock levels
  • Read datasheets — Access any section of a datasheet as structured text: pinout tables, electrical specs, register maps, timing diagrams, application circuits
  • Compare parts — Side-by-side comparison of up to 5 components with specs, pricing, and availability from multiple distributors
  • Validate designs — Check if a component will work within your operating conditions (voltage, current, temperature) against its absolute maximum ratings
  • Find alternatives — Discover substitute components with similar specs, same package, or compatible pinout when a part is unavailable or too expensive
  • Analyze images — Extract data from datasheet graphs, package drawings, and pin diagrams using vision AI

Recommended workflow

  1. search_parts to find candidates by keyword or part number
  2. get_part_details or compare_parts to evaluate options
  3. read_datasheet for detailed specs — start with section='summary' to get an overview and discover available sections, then fetch specific sections as needed
  4. check_design_fit to validate against your design constraints
  5. read_datasheet with mode='search' for any remaining questions about a specific part
  6. analyze_image when you need data from a graph, package drawing, or pin diagram

Tips

  • Use manufacturer part numbers (MPNs) like TPS54302 or LCSC numbers like C2837938 — bare values like "100nF" or "10K" are not part numbers
  • search_datasheets is best for broad spec-based discovery (e.g. "LDO with dropout below 200mV and quiescent current under 1uA")
  • search_parts is best for finding a specific part or browsing a category with pricing and stock
  • First extraction for a new part takes 10–20s as the PDF is downloaded and processed; subsequent calls are cached
  • Use prefetch_datasheets to warm up a batch of parts (e.g. from a BOM) before reading them individually
  • Prefer requesting specific sections from read_datasheet rather than reading everything at once to keep responses focused

search_partsSearch for electronic components by part number, description, or keyword. Start here — this is the best entry point for finding components. Queries all configured providers in parallel. Results are merged by MPN with indicative pricing and stock from each source. Each result includes datasheet_status ('ready', 'extracting', or 'not_extracted') so you know which parts have datasheets available for read_datasheet. Best with specific part numbers or keywords (e.g. 'STM32F103', 'buck converter 3A'). For spec-based discovery in natural language, use search_datasheets instead.
search_datasheetsSemantic search across all extracted datasheets. Finds components matching natural language queries about specifications, features, or capabilities. Best for broad spec-based discovery across all parts (e.g. 'low-noise LDO with PSRR above 70dB'). Only searches datasheets that have been previously extracted — not all parts that exist. For finding specific parts by number, use search_parts instead.
prefetch_datasheetsTrigger background datasheet extraction for multiple parts at once (up to 20). Free, non-blocking — returns immediately with the status of each part: 'ready' (already extracted), 'queued' (extraction started), or 'error'. Use this to warm up datasheets for a BOM before calling read_datasheet. Example: prefetch_datasheets(['TPS54302', 'ADS1115', 'LP5907']) IMPORTANT — only pass specific manufacturer part numbers (MPNs). Before calling, verify each part number: - Must be a real MPN like 'STM32F446RCT6', 'TPS54302DDCR', 'C100nF' — NOT a description or value. - Do NOT pass bare values like '100nF', '10K', '4.7uF', '300ohm' — these are component values, not part numbers. - Do NOT pass generic descriptions like 'LED red', 'capacitor 100nF', 'resistor 0603'. - Do NOT pass BOM reference designators like 'R1', 'C5', 'U3'. - If the BOM only has values/descriptions without MPNs, use search_parts first to find the actual MPN. - Passives from BOMs often lack MPNs — skip them rather than prefetching a bare value.
check_extraction_statusCheck the extraction status of one or more parts. Returns per-part status: 'ready' (datasheet extracted), 'extracting' (in progress), 'pending' (queued), 'failed' (extraction failed), or 'not_extracted' (unknown part). Includes current extraction step, elapsed time, and document ID for tracking. Free — use this to poll progress after prefetch_datasheets or read_datasheet.
get_part_detailsGet full details for a specific electronic component by manufacturer part number (MPN) or LCSC number. Returns specs, pricing, and stock from all configured providers, plus the cached datasheet summary if available. Includes datasheet_status ('ready', 'extracting', or 'not_extracted') and available_sections when ready. Set prefetch_datasheet=true to trigger background extraction — no extra charge. Use after search_parts to drill into a specific result. The part_number must be a specific manufacturer part number (e.g. 'TPS54302DDCR', 'STM32F446RCT6') or LCSC number (e.g. 'C2837938'). Do NOT pass bare component values ('100nF', '10K'), descriptions ('buck converter'), or reference designators ('R1', 'U3').
read_datasheetRead from a component's datasheet. Two modes: **Section mode** (default): Returns a named section. Start with section='summary' to get an overview and a list of available_sections. Then request specific sections by name. Section names are dynamic — any heading in the actual datasheet works (e.g. 'register_map', 'i2c_interface', 'power_management'). If a section name isn't found, automatically falls back to search mode. **Search mode**: Semantic search within the part's datasheet. Best for targeted questions (register bit fields, I2C config, specific specs). Use when you need to find specific information rather than a whole section. First call for a new part triggers extraction (30s-2min). Subsequent calls are cached. The part_number must be a specific manufacturer part number (e.g. 'TPS54302', 'STM32F446RCT6') or LCSC number (e.g. 'C2837938'). Do NOT pass bare component values ('100nF', '10K'), descriptions, or reference designators.
compare_partsCompare 2-5 electronic components side by side. Returns merged details from all providers and cached datasheet summaries for each part, making it easy to compare specs, pricing, and availability. Includes datasheet_status per part. Example: compare_parts(['TPS54302', 'LM2596', 'MP2359'])
check_design_fitValidate whether a component will work within your operating conditions. Checks the datasheet's absolute maximum ratings and recommended operating conditions against your design parameters. Returns PASS/FAIL/WARNING per parameter with margins. Example: check_design_fit('TPS54302', input_voltage=24, output_current=2.5, ambient_temp=70)
analyze_imageAnalyze an image from a component's datasheet using vision AI. Use this when read_datasheet returns a section containing images and you need to extract data from a graph, package drawing, pin diagram, or circuit schematic. Pass the image_key from the read_datasheet response (the storage path in the image URL). Optionally pass a specific question to focus the analysis. IMPORTANT: For precise numeric values (electrical specs, max ratings), prefer read_datasheet text tables first — they are more reliable than vision-extracted graph data. Use analyze_image for visual information not available in text: package dimensions from drawings, pin assignments from diagrams, graph trends, and approximate values from characteristic curves. Examples: - analyze_image(part_number='IRFZ44N', image_key='images/abc123.png') → classifies and describes the image - analyze_image(part_number='IRFZ44N', image_key='images/abc123.png', question='What is the drain current at Vgs=5V?')
find_alternativeFind alternative/substitute components for a given part number. Searches across providers for parts with similar specs, same package, or compatible pinout. Useful when a part is out of stock, too expensive, or you need a second source. Example: find_alternative('TPS54302', constraints='same_package,in_stock')
