SheetsData gives you instant access to electronic component data — specs, pinouts, package info, and more — extracted from manufacturer datasheets. No PDFs needed. ## 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 (pinout, electrical, package, etc.) 4. `check_design_fit` to validate against 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". - `search_datasheets` is best for broad spec-based discovery across all parts (e.g. "low-noise LDO with PSRR above 70dB"). - `read_datasheet` with section="all" returns all sections at once. - A datasheet nobody has read before usually takes 1-3 minutes, 5 or more for a large one or a busy queue. These are estimates, not deadlines. Start it early with `prefetch_datasheets`. Poll check_extraction_status (free) after poll_after_seconds (15-60 s); datasheets already read answer in about a second. - When a response carries `resolved_as` / `data_quality_warning`, the data is for a different MPN than you asked for; say so and confirm before relying on it. - When `read_datasheet` returns sections with images, use `analyze_image` to extract data from graphs, package drawings, pin diagrams, or schematics. Pass the image_key from the image URL. ## Prices Charged to your organisation per call: check_extraction_status, find_parts, get_part_details, prefetch_datasheets, request_datasheet_upload and search_parts are free; check_bom 2¢, compare_parts 2¢, find_alternative 2¢, read_datasheet 2¢, search_datasheets 2¢, analyze_image 5¢, check_design_fit 5¢ and confirm_datasheet_upload 10¢ per call. Each tool description starts with its price. A call that fails, or that returns status 'extracting', is not charged. ## datasheet_status values - 'ready': extracted and indexed; use read_datasheet, search_datasheets or analyze_image. - 'extracting' / 'in_progress' / 'queued' / 'pending': extraction running or scheduled. A datasheet nobody has read before usually takes 1-3 minutes, 5 or more for a large one or a busy queue. These are estimates, not deadlines. Poll check_extraction_status (free) after poll_after_seconds (15-60 s); datasheets already read answer in about a second. Stop at 'ready' or 'failed'. A response that says 'extracting' is not charged. - 'resolving': we are still looking for the datasheet's PDF (distributors, then a web search; under a minute a part, longer for a big batch). Not final: keep polling check_extraction_status. - 'not_extracted': known part, datasheet not fetched yet. Start it with prefetch_datasheets (up to 20 parts, free) or read_datasheet (starts on first read). If the response lists related_ready part numbers, their datasheet is readable now; check it covers your part. - 'no_source': the search for a public datasheet has finished and found none for this MPN. Check the part number (search_parts), or retry prefetch_datasheets later. Otherwise upload the PDF with request_datasheet_upload + confirm_datasheet_upload (private to your organisation). - 'unsupported': the PDF can't be extracted (scanned image-only, encrypted or corrupt). Upload a text-based PDF with request_datasheet_upload. - 'failed' / 'error': extraction errored; the response carries the reason. Retry with prefetch_datasheets or contact support. - 'rejected': the input wasn't a real MPN (a value like '100nF', a description or a reference designator). Fix the input. - 'deduplicated': another part in the family has the same datasheet; its content is served under that part's MPN. - 'trial_limit': the Free plan's daily allowance of new datasheets is used up; datasheets already read stay available. ## Important: valid part numbers - Always pass specific manufacturer part numbers (MPNs), not bare values or descriptions. - Valid: "STM32F446RCT6", "TPS54302DDCR", "GRM155R71C104KA88D", "C2837938" - NOT valid: "100nF", "10K", "4.7uF", "0603 resistor", "LED red", "R1", "C5", "U3" - Bare component values (100nF, 10K, 300ohm) are NOT part numbers — they will waste extraction resources and return wrong results. Use `search_parts` first to find the MPN. - BOM reference designators (R1, C5, U3) are circuit labels, not part numbers. - Test points (TP1, TP_GPIO_1), fiducials (FID1), mounting holes (MH1), and other mechanical BOM items are PCB features, not components — never pass these. - Do NOT concatenate MPNs with LCSC numbers (e.g. "SMAJ24A-C148222"). Pass the MPN ("SMAJ24A") or LCSC number ("C148222") separately. - Board/module names (e.g. "CM5IO_ComputeModule5") are not MPNs. - When processing a BOM, skip rows that only have values/descriptions and no MPN column. Also skip test points, fiducials, mounting holes, and other non-component items. ## Important: managing context size - Prefer requesting specific sections from `read_datasheet` (e.g. "summary", "pinout", "electrical") rather than "all". The "all" option returns the entire datasheet and can easily fill your context window. - Start with "summary" to get an overview, then fetch specific sections as needed.
