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.

  • 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.
