Completed the datasheet review for Molex 52271-3069. The official Datasheet URL was already set, so I did not change it; the 30-contact signal footprint matches the datasheet well, but pin metadata is incomplete and the mounting-pad/keepout details need visual verification.
Detailed findings are in Part Datasheet Cross-Check: Molex 52271-3069.
Open items:
- All symbol pins are still
Unspecifiedand missing pin descriptions. - MP1/MP2 fitting-nail pads and no-footprint/keepout regions should be checked against the official Molex drawing before production use.
Suggested next steps:
- Update pin types/descriptions for pins 1–30 and MP1/MP2.
- Visually verify or revise MP1/MP2 pad geometry from the Molex recommended PCB pattern.
- Add explicit connector keepouts/no-footprint areas if needed.

Schematic Symbol Cross-Check
Table
| Item | Project state | Assessment |
|---|---|---|
| Signal terminals | Pins 1 through 30 present | Matches 30-circuit datasheet |
| Mounting pads | MP1 and MP2 present | Matches fitting nail / solder hold-down concept |
| Pin numbering | 1-30 sequential; MP1/MP2 separate | Correct and clear |
| Pin Type | All terminals show Unspecified | Library-quality mismatch / incomplete metadata. Connector signal pins should normally be Passive or Bidirectional; MP1/MP2 should be Mechanical or Passive if Mechanical is unavailable. |
| Pin Description | No functional pin descriptions present | Incomplete. Suggested descriptions: FFC/FPC contact N for pins 1-30 and Solder fitting nail / mechanical hold-down for MP1/MP2. |
| Bottom-contact orientation note | Not represented in pin descriptions | Consider documenting bottom-contact orientation and pin-1/cable insertion direction in the symbol or part notes. |
Footprint Cross-Check
Signal-contact pad array
Table
| Datasheet expectation | Project footprint | Assessment |
|---|---|---|
| 30 SMT signal pads | Pads 1-30 present | Matches |
| 1.00 mm pitch | Pads positioned at x = -14.5 mm to +14.5 mm in 1.0 mm increments | Matches |
Contact span (N-1) = 29.0 mm for 30 circuits | Project span = 29.0 mm | Matches |
| Recommended signal land width about 0.6 mm | Project pad width 0.600 mm | Matches |
| Recommended signal land length about 1.9 mm | Project pad length 1.900 mm | Matches |
| Pin-1 marking | Silk pin-1 dot near pad 1 | Present |
Fitting nail / mounting pads
Table
| Datasheet evidence | Project footprint | Assessment |
|---|---|---|
| Fitting nails present for prevention of PCB pattern peeling | MP1/MP2 present | Matches conceptually |
| Extracted drawing values include 2.1 mm, 4.2 mm, 1.65 mm, 1.6 mm, 0.6 mm, 2.8 mm around fitting nail recommended pattern | MP pads at x = ±17.650 mm, y = -1.7 mm, size 2.100 mm × 2.800 mm | Needs manual visual confirmation against the Molex drawing. The extracted values may mix land sizes, positional references, and no-footprint-area dimensions. If 4.2 mm is the actual recommended land length, the current 2.8 mm MP pad length may be too short; if 2.8 mm is the actual land length and 4.2 mm is a reference span, the project may be correct. |
Datasheet includes NO FOOT PRINT AREA note | Footprint contains pads, fab/silk/courtyard-like lines, but no explicit keepout/no-footprint-area rules were identified | Potential omission. Add/verify mechanical keepouts for actuator/FPC insertion and no-footprint zones before production use. |
Mismatches / Issues Flagged
- Pin metadata incomplete: all schematic terminals have
Pin Type = Unspecified. - Pin descriptions missing: pins 1-30 and MP1/MP2 have no descriptive function text.
- Mounting pad dimensions/position need visual verification: signal pads match well, but MP1/MP2 interpretation is ambiguous from OCR extraction of the Molex drawing.
- No-footprint / keepout areas not explicitly modeled: the datasheet drawing includes no-footprint-area notes; project footprint does not show explicit keepout rules in the inspected layout data.
- Product URL and human-readable description are not explicitly stored as project-level properties: datasheet-backed values are known, but not currently captured as metadata fields.
Conclusion
The core part identity and the 30-contact signal footprint appear correct against the official Molex drawing: count, pitch, span, and signal pad dimensions match. The main production-risk item is the fitting-nail / mounting-pad land pattern and associated keepout/no-footprint areas, which should be visually checked against the official Molex recommended PCB pattern before relying on this footprint for fabrication. The symbol is functionally complete in pin count but needs better pin types and descriptions for library quality.
