A connector product page is a practical starting point for a PCB and harness inquiry, but it is not a released design package. The live EPPTC catalogue identifies TE Connectivity 776231-1 as an AMPSEAL automotive header record. It shows a 35-position, three-row, board-to-cable/wire header description with 4.00 mm pitch wording, a shrouded four-wall format, panel-mount and through-hole mounting wording, plus power-and-signal application language. Record those fields with the source URL and access date. Do not turn them into approval of a PCB footprint, mating connector, sealing result, harness, current path or installed assembly.
1. Preserve the complete catalogue identity
Keep the brand, full part number and family wording together: TE Connectivity 776231-1 AMPSEAL header. Preserve the original wording from the BOM, drawing, sample label or customer request, rather than reducing it to “AMPSEAL connector.” Save the product-page URL, access date, project reference and person requesting the check. A full identity record is the simplest way to prevent an RFQ, layout review or receiving note from drifting to another position count, coding option or product family.
2. Separate page observations from layout release
The page’s header, pitch, row-count, orientation and through-hole wording can make a documentation request precise. They do not establish a released land pattern, drill size, keep-out area, retention feature, panel cut-out, solder process or board stack-up. Build a review table with two visible columns: “observed on catalogue page” and “verified in current controlled source.” When a value is confirmed, add the document number, revision, reviewer and decision date. When it is not confirmed, keep it open instead of inferring it from a photo, a family name or an older project.
3. Check interface evidence independently
An apparent 35-position header description does not prove a mating plug, terminal assignment, keying, seal stack, wire range or finished harness relationship. Those decisions need the current manufacturer interface documents and the project’s controlled design data. This distinction is especially useful when a purchasing request carries only a part number and a partial application note. Treat each unknown interface field as a question for the documentation owner, not as a gap to fill with catalogue language.
4. Keep PCB and procurement questions traceable
A useful handoff identifies the exact part number, required document revision, board reference, intended review purpose and open questions. Separate technical evidence from commercial questions such as quantity, packaging, lead time and quotation. The live record shows tray packaging and a standard-pack quantity, but those fields are observations that may change and are not availability promises. Keeping technical and commercial items separate helps a supplier or internal reviewer answer the real question without mistaking a catalogue entry for a build authorization.
5. PCB documentation checklist
- Use the complete 776231-1 part number on the BOM, drawing review and inquiry.
- Request the current controlled interface and PCB documentation by revision, not a screenshot alone.
- Record which catalogue fields were observed and which fields remain unverified.
- Name the board owner, reviewer, decision date and evidence location for every closed point.
- Keep quantities, packaging and quotation requests outside the technical approval decision.
6. Use related pages as independent references
EPPTC also publishes an 8-968972-1 automotive-housing record. It may help a reader locate separate TE Connectivity terminology or documentation paths, but this article does not state that it mates with, accepts, fits, seals, replaces or is otherwise compatible with 776231-1. Any relationship must be established only by the current manufacturer documentation and approved project data.
FAQ
Does the listed 4.00 mm pitch approve my PCB footprint?
No. It is a catalogue observation. Verify the released drawing, footprint and revision required for the specific board.
Can the product page establish a mating or sealing relationship?
No. Use current manufacturer interface documents and approved project data for any mating, terminal, seal or harness decision.
What should I send with a documentation request?
Send the full part number, board or application context, document revision requested and a concise list of open questions.
Conclusion
A disciplined TE Connectivity 776231-1 AMPSEAL header review begins with the exact identity and treats online fields as traceable discovery evidence rather than a shortcut to release. Preserve the source, keep layout and interface questions explicit, and use controlled documents for every engineering decision.
