|---|---|
| Pin numbering | Drawing shows row labels and numbering scheme (e.g., “D C B A / A B C D; pins are numbered 8 7 6 5 4 3 2 1 on both sides as shown”). Use the diagram to set the corner pin-1 orientation. |
| Mating info | Mates with Sullins 2.54 mm contact center male header series (0.64 mm square posts). |
Ordering/part coding
- The drawing references part number coding for insulator material, plating, and temperature specs but does not include the coding table.
- Pattern shown: “_P_C___LFBN-RC”. The detailed code key must be obtained from the series/catalog page if needed for exact material/plating/temp options.
Step 4 — Cross-check of symbol and footprint vs datasheet
Schematic symbol
- The schematic uses 14 single-pin Terminal symbols (e.g., 1, 2) instead of a single 14-pin connector symbol with a J-prefix.
- Risks:
- BOM/ordering: Generic Terminals do not carry the MPN; the part won’t roll up correctly in a design BOM.
- Net mapping: Managing numbering/row orientation across many single pins is error-prone compared to a single connector symbol with well-defined pins 1–14.
- Mismatch: The project’s part-level designator prefix is “J”, while the individual Terminal symbols show a “P” designator prefix. This is inconsistent for a connector part.
Footprint
- Footprint node: cf148286-031a-4e92-a7a7-bacd6ab12c71.defaultFootprint
- Pad count: 14 pads present (matches 2 × 7).
- Grid and spacing: Pads placed on a 2.54 mm × 2.54 mm grid; two rows at y = 0 and y = −2.54 mm with x from 0 to 15.24 mm in 2.54 mm steps. This matches the datasheet’s 2.54 mm pitch for dual row.
- Hole and pad size: Drill = 1.02 mm; pad size = 1.52 mm. The 1.02 mm hole matches the datasheet’s recommended PCB hole size (1.02 ± 0.05 mm).
- Pin-1 marking: Present (silkscreen marker near pad 1), aligning with best practices and aiding orientation.
- 3D model: Included (PPPC072LFBN-RC.stp), consistent with the MPN.
- Naming mismatch to flag: The footprint asset/module is named “XPYC072LFBN-RC” while the MPN is “PPPC072LFBN-RC”. This naming inconsistency can cause confusion during library management or part linking.
Actionable flags and recommendations
- Create/replace with a single 14-pin connector symbol using designator prefix “J” and pins numbered 1–14 per the datasheet diagram. Then map symbol pins 1–14 to the footprint pads 1–14.
- Ensure the final symbol is associated with the MPN “PPPC072LFBN-RC” so BOM roll-up is correct.
- Consider renaming the footprint to align with the MPN (PPPC072LFBN-RC) for consistency.
- If exact insulator material, contact plating, and temperature ranges are required on the part properties, obtain the PPPC series part-number coding table and populate those fields accordingly.
If you’d like, I can proceed to:
- Replace the 14 single-pin Terminals with a proper 14-pin connector symbol and connect all pins to the existing footprint.
- Align the footprint name with the MPN.
