Summary. EPPTC lists MG645724-5 as a KET 025 Series sealed, 14-position wire-to-wire connector housing with TPA. KET’s public search and family records identify MG645724-5 or the MG645724 family as a 025 WP 14F assembly and point to related mating records. Those facts are useful evidence anchors, but they are not an installation release. This guide explains how to preserve the exact suffix, review the drawing, control terminal and counterpart identities, and assemble a traceable request package. It does not approve a terminal, seal, wire, cavity loading, tooling, process setting, fit, substitute, stock position, price or finished harness.
Freeze the exact part identity before comparison
Review the EPPTC MG645724-5 product record as the local catalogue starting point. Keep the complete “-5” suffix in the enquiry, BOM, sample label, inspection record and document index. A drawing or manufacturer page that uses the base family number MG645724 may support family-level research, but it must not silently replace the ordered suffix. Record which source shows the exact suffix and which source covers the base family; this distinction makes later engineering review auditable.
The EPPTC record describes a black PBT housing, 14 positions, sealing, TPA and the 025 Series. KET’s public base-family page uses its own current family presentation. If dimensions, material wording, color, wire range or related-part notation differ between a local record, search result and drawing, treat the difference as an open verification item. Do not blend values from separate revisions into a synthetic specification.
Turn “sealed” into a complete evidence set
A sealed housing is only one part of a sealed interface. The project package should identify the exact terminals, wire seals or cavity plugs, secondary lock state, wire construction, insulation diameter, cavity loading and mating-side components. It should also define how unused cavities are handled and how seal damage, terminal back-out and incomplete TPA seating are inspected. The public product label “sealed” does not establish an ingress rating for the assembled harness or approve a test method.
Separate catalogue facts from process decisions. The published 14-position and TPA fields are useful identity checks, while insertion depth, pull force, crimp geometry, seal position and leak-test acceptance belong to applicable controlled documents. If the required revision is unavailable, mark the step as blocked rather than copying a setting from a visually similar 025-family connector.
Verify every mating and terminal relationship
KET’s public family information references MG655671 and MG655672 mating connectors and ST731363 or ST731364 terminal families. These references narrow the research space; they do not select an exact counterpart suffix, terminal plating, wire range or cavity assignment for a project. The official MG655672-4 record is useful as a separate counterpart evidence item, but compatibility still needs confirmation for the exact proposed configuration.
Create one evidence row for each proposed housing, counterpart, terminal, seal and accessory. Include manufacturer, full part number, document number, revision, source URL, access date and the person or process responsible for approval. A relationship should remain “proposed” until the current drawing or application document explicitly supports it.
Read the drawing as a controlled interface record
The KET MG645724 family drawing provides a first-party interface reference. Review its title block, revision history, views, cavity or locking details and any notes that govern inspection. Save the original PDF or its controlled reference according to the project document system. A screenshot, cropped dimension or distributor table is not an adequate substitute because it can omit revision and note context.
Before release, compare the drawing against the physical sample and the purchasing identity. Confirm that the sample marking, keying, latch direction, cavity count and secondary-lock state correspond to the record under review. Escalate a mismatch instead of forcing the sample into the nearest catalogue description.
Build an auditable installation request
A useful request package exposes unknowns and keeps commercial details separate from engineering evidence. It should contain enough context for a reviewer to reproduce the source trail and understand the intended environment without treating this article as an approval.
- Record MG645724-5 exactly, including suffix, manufacturer and project usage.
- Attach or reference the current KET product record and drawing with access dates and revisions.
- List every proposed terminal, seal, plug, TPA or secondary lock and mating housing by exact part number.
- State the wire construction, conductor size, insulation diameter, cavity map and unused-cavity treatment.
- Request the applicable crimp, insertion, extraction, inspection and sealing acceptance documents.
- Record open discrepancies, the responsible reviewer and the evidence required to close each item.
- Keep quantity, packaging, lead time and price in a separate commercial section.
FAQ
Does MG645724-5 alone define a complete sealed connection?
No. It identifies a housing record. A complete connection also depends on the exact mating component, terminals, seals or plugs, wire, cavity loading, assembly process and verification criteria.
Can MG655672-4 be approved as the counterpart from a web page?
No. The page is useful first-party evidence for that distinct part record. The exact mating relationship and project configuration still require current controlled manufacturer documentation.
Can the 025 Series name be used to select tooling or substitutes?
No. A series label helps navigation only. Tooling, terminals, interchangeability and process limits must be verified for the exact part and document revision.
Conclusion
For KET MG645724-5, preserve the full suffix, separate family evidence from exact-part evidence, and convert every installation assumption into a named verification task. That approach keeps catalogue research useful without presenting it as engineering or production release.
