A connector product page is a useful starting point for a high-current harness inquiry, not a release package. EPPTC currently identifies YAZAKI 7122-4123-30 as a terminal-box record. Its published catalogue wording includes a 58 Connector L Type family, a two-position, male, wire-to-wire, unsealed housing description and a 9.5 mm tab-size field. Capture the source URL and access date with those observations. Do not turn a catalogue record into approval of a finished harness, a mating interface, a terminal choice, a current path or an installed assembly.
1. Keep the catalogue identity intact
Record the brand, full part number and product type together: YAZAKI 7122-4123-30 terminal box. Keep the wording from the BOM, drawing, sample label or customer request rather than shortening it to a generic connector. Add the project reference, requester and document date. This simple discipline helps prevent a sourcing, engineering or receiving note from drifting to another series, position count, terminal size or sealing status.
2. Separate page observations from controlled evidence
The live record can make a documentation request precise: it displays black colour wording, nylon-66 material wording, clip-installation wording and external dimensions. These are catalogue observations at the access date. They do not by themselves establish a drawing revision, mounting-hole decision, retention result, environmental suitability, production process or vehicle-level approval. Use a two-column review table: “observed on catalogue page” and “verified in current controlled source.” Close a field only after recording the document number, revision, reviewer and decision date.
3. Treat current-related fields as reference data
The page includes a 60 A reference-current field and electrical-resistance, insulation-resistance and withstand-voltage wording. Preserve the labels, units, source and access date exactly as shown. A reference field is not a system rating, a wiring recommendation or permission to use the part in a particular circuit. The actual decision still needs the applicable manufacturer documentation and the project’s controlled electrical, thermal, wire and protection data. If any condition is unknown, keep it as an open question instead of converting a catalogue value into a design limit.
4. Keep terminal and interface questions open
The catalogue also lists terminal part-number fields and one mating-part-number field. Those entries are leads for a documentation request, not proof of an approved relationship in your project. Confirm the current interface drawing, terminal application data, cable specification, keying, service procedure and revision through controlled sources before asserting fit, assembly or compatibility. This boundary is especially important when a request contains only a part number and a photo.
5. Build a traceable handoff
A useful handoff names the exact 7122-4123-30 record, the intended application context, the documents requested by revision and the unresolved questions. Keep technical evidence separate from quantity, packaging, lead-time and quotation questions. The catalogue contains packaging and origin-related fields, but they can change and do not promise stock or supply. A clean separation lets engineering, purchasing and quality answer the right question without treating an online listing as a build authorization.
6. Documentation checklist
- Use the complete YAZAKI 7122-4123-30 part number in the inquiry, BOM review and evidence log.
- Save the catalogue URL and access date beside every observed field.
- Request current controlled drawings and application documentation by revision.
- Record terminal, interface, cable and installation questions as open items until verified.
- Keep commercial sourcing questions outside the engineering approval decision.
7. Use related pages only as independent references
EPPTC also publishes YAZAKI records for 7114-3250 and 7283-1020. They can help a reader locate separate catalogue terminology and documentation paths. This article does not state that either record mates with, fits, replaces, accepts, seals with or is otherwise compatible with 7122-4123-30. Establish every relationship solely from current manufacturer documentation and approved project data.
FAQ
Does the 60 A reference field approve my circuit?
No. Preserve it as catalogue reference data and verify the controlled documents and project conditions required for the actual circuit decision.
Can I assume the listed terminal or mating fields prove compatibility?
No. They identify questions to verify. Use current manufacturer interface documentation and approved project data before making any relationship claim.
What should accompany a documentation request?
Send the full part number, application context, required document revision, source URL and a short list of unresolved questions.
Conclusion
A disciplined YAZAKI 7122-4123-30 terminal-box review starts with the exact catalogue identity and treats online fields as traceable discovery evidence, not engineering release. Preserve the source, state open interface and current-related questions clearly, and rely on controlled documentation for every design or procurement decision.
