Component relationships

Matching components

A complementary component is listed separately from an alternative or cross-reference. This relationship does not establish interchangeability or application approval.

No complementary components are attached to this record.

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.

  • 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.
  • Application fit: Confirm electrical, mechanical and application requirements before substitution.
  • Application fit: Confirm electrical, mechanical and application requirements before substitution.
  • Application fit: Confirm electrical, mechanical and application requirements before substitution.
  • Application fit: Confirm electrical, mechanical and application requirements before substitution.
  • Do not treat a cross-reference classification as a substitution approval; confirm the application against the cited sources.

Evidence provenance

Why this record is trusted

Sources are grouped by publication so you can inspect the record review, every covered claim, and the exact locators behind it without returning to lookup.

Confidence: High
Record review: Audited
Evidence basis: Manufacturer published source record

This is a curated canonical record with claim-level source locators; it is not a substitution guarantee.
