Relationship: Complementary component
Confidence: unknown
Why this relationship is present
The available relationship evidence is incomplete or conflicting.
Panel-fastener fit status
Documented fit means the four approved TMT/grip, mounting, actuation, and environmental claims align. It is not engineering approval or a substitution approval.
- TMT / grip rangeNo approved explicit tmt / grip range claim is documented for the source and candidate parts.
- Mounting styleNo approved explicit mounting style claim is documented for the source and candidate parts.
- Actuation mechanismNo approved explicit actuation mechanism claim is documented for the source and candidate parts.
- Environmental dutyNo approved explicit environmental duty claim is documented for the source and candidate parts.

Why this match
Identity first, relationship second.
The submitted manufacturer and part number resolve directly to the curated canonical record after normalization.
The record carries manufacturer-published source record and claim-level source locators. That evidence describes the record; it does not by itself guarantee substitution.
What to verify before substitution
Close the explicit gaps.
- Connection configuration: the source set does not document a value.
- Colour: the source set does not document a value.
- Current rating: the source set does not document a value.
- Voltage: the source set does not document a value.
- Dimensions: the source set does not document a value.
- Mounting configuration: the source set does not document a value.
- Terminals: the source set does not document a value.
- Compatible fuse range: the source set does not document a value.
- TMT / grip range: the source set does not document a value.
- Mounting style: the source set does not document a value.
- Actuation mechanism: the source set does not document a value.
- Environmental duty: the source set does not document a value.
- Do not treat a cross-reference classification as a substitution approval; confirm the application against the cited sources.
