Connector Datasheet Review

flux

Flag these mismatches:
  1. Footprint drill diameter is too large
    • Project: 1.35 mm drill
    • Sullins drawing 10492-H: recommended PCB hole Ø0.040 ±0.002 in = 1.02 ±0.05 mm
    • Acceptable range: about 0.97–1.07 mm
    • 1.35 mm is outside the recommended range and should be flagged.
  2. package_case_code is incorrect
    • Project: TO
    • Part is a 2.54 mm single-row female header, not a TO-package semiconductor.
    • Should be something like single-row header / SIP / 1x22 2.54 mm female header, depending on the property schema.
    • Flag package_case_code: TO as wrong/misleading.
  3. Symbol pin metadata is incomplete
    • Project: terminal pins numbered 1–22, but pin type is unspecified and there are no descriptions.
    • For a passive connector/header, “passive” or equivalent connector pin type is usually expected.
    • Descriptions such as “Pin 1”, “Pin 2”, etc. are not electrically critical, but the lack of pin type/description is a documentation-quality issue.
    • Flag as incomplete symbol metadata, not necessarily a fatal electrical mismatch.
Acceptable / matching items:
  1. 22-position single-row female header
    • Project: 22-position single-row 2.54 mm female header
    • Drawing: PPPC221LFBN-RC corresponds to 22 positions, single row, female header.
    • Acceptable.
  2. Pad numbering 1–22
    • Project footprint has KiCad pads 1–22
    • Drawing/device has 22 contacts
    • Acceptable.
  3. Pad x-location / pitch
    • Project: pads at x = 0 to 53.34 mm, pitch 2.54 mm
    • Drawing: pitch 2.54 ±0.05 mm, dimension A = 53.34 mm for 22 positions
    • Since 21 intervals × 2.54 mm = 53.34 mm
    • Acceptable.
  4. Pad 1 rectangular
    • Project: pad 1 rectangular
    • This is a conventional and acceptable footprint convention for pin-1 identification.
    • Acceptable.
  5. Pad diameter / size
    • Project: pad size 2.025 mm
    • Drawing specifies recommended hole size, not necessarily copper land diameter.
    • A 2.025 mm pad around a ~1.02 mm hole gives about 0.50 mm annular ring per side, which is reasonable.
    • Acceptable unless a separate manufacturer land-pattern requirement contradicts it.
  6. Fab outline length
    • Project fab outline x: -1.52 to 55.21 mm, total 56.73 mm
    • Drawing body length B: 56.38 mm
    • Difference: 0.35 mm total, about 0.175 mm per side
    • This is close and likely acceptable for a fabrication/body outline, depending on outline convention and tolerances.
    • Probably acceptable / minor difference only.
  7. Fab outline width
    • Project fab outline y: ±1.27 mm, total 2.54 mm
    • Drawing body width: approximately 2.54 mm
    • Acceptable.
  8. Datasheet URL
    • Project URL: http://www.sullinscorp.com/drawings/78_P(N)PxCxxxLFBN-RC,_10492-H.pdf
    • This points to the Sullins drawing 10492-H family document.
    • Acceptable.
  9. MPN
    • Project: PPPC221LFBN-RC
    • Drawing/family: compatible with PPPCxxxLFBN-RC series, 22-position variant
    • Acceptable.
  10. Manufacturer Name
  • Project: Sullins
  • Official manufacturer: Sullins Connector Solutions
  • Acceptable.
  1. Electrical/environmental ratings
  • Drawing: 3 A/contact, 250 VAC/DC, -40 to +105 °C
  • If the project omits these ratings, that is a missing useful metadata issue, but not a contradiction with the stated footprint/symbol facts.
  • Acceptable as omitted metadata unless the part model is expected to include full ratings.
Summary: the main hard mismatch is the 1.35 mm drill, which should be closer to 1.02 mm per the Sullins recommendation. Also flag the incorrect package_case_code: TO and the incomplete symbol pin metadata. The position count, pitch, pad numbering, body outline, MPN, manufacturer, and datasheet URL are acceptable.

Completed the datasheet-backed part review and created the detailed report here: Part Information Review — PPPC221LFBN-RC.
Open items:
  • Datasheet URL was already set, so no update was needed.
  • Main flagged mismatch: footprint drill is 1.35 mm, while Sullins recommends Ø1.02 ±0.05 mm.
  • Also flagged: misleading TO package/case code and incomplete symbol pin metadata.
Suggested next steps:
  1. Update the footprint drill size to the datasheet value.
  2. Correct the package/case metadata.
  3. Add passive pin types and simple contact descriptions for pins 1–22.

Mismatches / Issues to Flag
  1. Footprint drill diameter mismatch — footprint uses 1.35 mm drills, while the Sullins drawing recommends Ø1.02 ±0.05 mm holes. This is the main manufacturability/fit mismatch.
  2. Package/case code is misleading — library data reports package_case_code = TO, which is inappropriate for this 1x22 2.54 mm through-hole female header.
  3. Symbol pin metadata is incomplete — all terminal pin types are Unspecified, and pin descriptions are blank. Since this is a passive connector, these should ideally be marked as passive connector pins with simple contact descriptions.
  4. Fab outline length is slightly long — observed 56.73 mm vs datasheet B = 56.38 mm. This is minor compared with the drill mismatch but should be checked if exact body/courtyard accuracy matters.
Items That Match
  • MPN matches the Sullins family and 22-position variant.
  • Existing Datasheet URL points to the official Sullins 10492-H drawing family.
  • 22 schematic terminals, 22 footprint pads, single-row geometry, 2.54 mm pitch, and 53.34 mm pin-1-to-pin-22 span all match.
  • Part description as a female 2.54 mm straight header is consistent with the datasheet.
  • Electrical ratings in the library description align with the datasheet: 3 A/contact, 250 V AC/DC, -40°C to +105°C.
  1. Change through-hole drill diameter from 1.35 mm to the datasheet-recommended 1.02 mm nominal, keeping an adequate annular ring.
  2. Replace package_case_code = TO with a connector/header-specific package descriptor if the property is editable.
  3. Set all symbol terminals to passive connector pins and add simple pin descriptions such as Contact 1 through Contact 22.
  4. Re-check or adjust fab/body outline length to 56.38 mm if exact body outline fidelity is required.
