MCP3202 Part Review

A

adrian95

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll inspect the part metadata/symbol/footprint, find and set the official datasheet if missing, then cross-check pins and summarize any mismatches.

Completed the datasheet-backed review for MCP3202-BI/P and saved the detailed tables/results in Part Review - MCP3202-BI/P.
Open items:
  • No major MPN, pinout, package, or footprint mismatch found.
  • Pin Types are all Unspecified, and pin descriptions are missing.
  • Existing datasheet URL is populated but points to an uploaded PDF; the official Microchip URL was identified as an optional replacement.
  • Description has a minor typo: Dual 12-bit- ADC.
Suggested next steps:
  1. Update terminal Pin Type and Pin Description properties.
  2. Clean up the part description.
  3. Optionally replace the Datasheet URL with the direct Microchip PDF URL.

Part Review - MCP3202-BI/P
Scope
Reviewed all available part information in the current Flux part project against the Microchip MCP3202 datasheet: MPN, manufacturer, package, pin count, description, part properties, schematic symbol terminals, terminal pin properties, and footprint geometry.
Sources
  • Existing project Datasheet URL: https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/377373b5ef4fe199d14db244b49fcdbf5897ed021ac3b0ca4aeff55d3cea2b2a.pdf
  • Official Microchip datasheet found during review: https://ww1.microchip.com/downloads/en/DeviceDoc/21034F.pdf
  • Microchip package outline reference found during review: Drawing C04-018-P / C04-018B for 8-lead 300 mil PDIP.
Because a Datasheet URL was already present in the part properties, no Datasheet property update was performed. The existing URL appears to be an uploaded copy rather than the direct Microchip URL; consider replacing it with the official Microchip URL if direct vendor links are preferred.

Footprint cross-check
Existing footprint asset: DIP781W56P254L950H533Q8N.kicad_mod.
Observed footprint characteristics:
  • 8 through-hole pads.
  • Pad pitch along each row: 2.54 mm.
  • Row spacing: 7.81 mm between pad columns.
  • Pad size: 1.159 mm diameter/width.
  • Drill: 0.759 mm.
  • Pin 1 uses rectangular pad marker.
  • Fab outline is approximately 7.112 mm x 10.16 mm, with pin-1 chamfer/notch indication.
Datasheet/package check:
  • MCP3202-BI/P package is 8-lead Plastic DIP, 300 mil body.
  • Datasheet package pitch is 0.100 in BSC = 2.54 mm.
  • PDIP body width nominal is 0.250 in; shoulder/lead row geometry is compatible with a standard 300 mil DIP land pattern.
Footprint verdict: The footprint is suitable for an 8-pin 300 mil PDIP and matches the expected pin count and pitch. No datasheet-level footprint mismatch was found.
Manufacturability note: The 1.159 mm pad with 0.759 mm drill leaves about 0.20 mm annular ring per side, which is plausible but not generous. If this part is intended for low-cost through-hole fabrication or hand soldering, consider using a larger pad diameter where design rules allow.
Mismatches and concerns
  1. No major MPN, package, pin count, pinout, or footprint-family mismatch found.
  2. All schematic terminal Pin Type values are Unspecified; update them for better ERC and library quality.
  3. Pin Description properties are missing for all eight pins; add datasheet-derived descriptions.
  4. The project description has a minor typo: Dual 12-bit- ADC; recommended wording is dual 12-bit ADC, 100 ksps, SPI-compatible, 8-pin PDIP.
  5. The Datasheet URL property is populated, but it points to an uploaded PDF copy rather than the direct official Microchip URL. Optional improvement: replace with https://ww1.microchip.com/downloads/en/DeviceDoc/21034F.pdf.
  6. Footprint annular ring is somewhat compact; acceptable in many flows but worth checking against the target fabricator's minimum annular ring rules.
  • Update the eight terminal Pin Type properties from Unspecified to the datasheet-derived electrical types.
  • Add Pin Description properties for all eight terminals.
  • Clean up the description text.
  • Optionally replace the uploaded Datasheet URL with the official Microchip PDF URL if vendor-hosted datasheet links are preferred.
