An unused connector cavity is still part of the assembly configuration. TE Connectivity identifies 828922-1 as a cavity plug, and its official page places it under Timer Connector System. This guide answers documentation and inspection questions about closing unused positions. The banner is a generic review scene, not an exact image of the orderable part.
1. Is a cavity plug the same as a wire seal?
Keep the two functions distinct when writing a BOM or receiving checklist. A cavity plug addresses an unused position, while a wire-seal selection concerns a position containing a conductor and contact. Do not convert an accessory name into a complete housing specification. Identify the exact housing, contact population and sealing arrangement separately before reviewing the applicable assembly requirements.
A catalogue category is useful for finding records, but it cannot establish that two items share an interface or may replace each other. Preserve the complete 828922-1 identifier through the enquiry, sample label and inspection reference. If a supplier proposes another plug, treat that proposal as a new evidence question rather than accepting a shared colour or general sealing description.
2. Which document fixes the part identity?
Use the official product page as the identity anchor and the customer drawing as the controlled geometry reference. TE drawing 828922, revision L9, contains an exact 828922-1 row and other orderable variants. Locate the correct row before reading any drawing detail. A family number on a PDF does not mean that every row represents the same item.
Record the source URL, drawing identifier, revision and the exact row used in the comparison. Keep the document itself with the review file so a later reader can reproduce the decision. If packaging, a sample or a supplier statement disagrees with the retained record, keep the discrepancy visible and request a traceable clarification before releasing the affected material.
3. Can one instruction cover every sealed housing?
The linked TE instruction sheet 411-78008, revision A2, concerns a Sealed MQS/JPT 81/40-position connector configuration. It discusses closure of vacant cavities as part of that assembly. Its presence on the accessory page is a document-search lead; apply its assembly details only after checking that the actual housing and configuration fall within its scope.
Do not transfer an insertion depth, tool, force or sequence to an unnamed housing simply because it also needs a cavity plug. Request the configuration-specific instruction and distinguish its mandatory checks from the project inspection plan. This article provides no universal installation setting and establishes no mating or compatibility relationship for a housing not identified in the evidence packet.
4. What should the inspection record contain?
Start from a cavity-population map for the released configuration. It should show which positions contain contacts and which are intentionally unused, using the numbering convention of the actual controlled drawing. Then connect each unused position to its specified closure component and applicable work instruction. Avoid relying on memory when the same housing supports several circuit populations.
- Identity: retain the exact housing and plug numbers, lot references and controlled source revisions.
- Population: record occupied and unused positions against the released circuit configuration.
- Observation: document the required closure condition using the applicable instruction and traceable unit identification.
- Disposition: isolate unresolved identity or assembly discrepancies and preserve their closure evidence.
A photograph can support a specific observation, but it does not certify an entire lot or establish a finished connector environmental rating. Keep any required sealing validation and acceptance criteria attached to the complete configuration. Sampling, rework and release decisions belong to the responsible project quality process, with their actual records and defined scope.
5. Common purchasing and change questions
Does an active manufacturer status mean stock is available? No. Obtain a current written commercial reply for the exact orderable item, quantity, packaging and delivery conditions. A published catalogue record does not establish price, inventory or lead time. Keep those transaction facts separate from the technical document review so later readers know when each statement was valid.
Can an alternate plug inherit the existing inspection plan? Reopen the affected comparison first. Identify both orderable parts, the proposed housing and the evidence covering their interfaces and assembly requirements. Preserve unresolved differences explicitly. Shared family labels are discovery aids, while a substitution decision requires the responsible engineering process and traceable configuration evidence.
Does the automotive navigation page approve this part for a vehicle? It helps discover catalogue records. No confirmed internal application mapping is stored for this product, so the link is not an application claim. Identify the actual installation environment and complete assembly requirements in the project file before assigning suitability or compliance conclusions.
6. Conclusion: request the complete closure evidence
A useful 828922-1 inspection packet connects the exact accessory, controlled drawing row, actual housing and unused-position map. It keeps the boundaries of each source visible and preserves questions that remain unresolved. When a housing suffix, circuit population or closure component changes, revisit the affected records rather than carrying the previous decision forward without checking its scope.
For a document enquiry, provide 828922-1, the complete housing number, the unused-cavity map and the question observed during receiving or assembly. Request the applicable drawing and installation instruction, then retain the actual response with the controlled file. That handoff supports a traceable project decision without turning an editorial FAQ into engineering approval.
