Parameter Comparison

Engineering Selection Recommendations

Part 11869 is the direct functional equivalent to 11578. Both parts share identical electrical and mechanical specifications for wire gauge, termination method, insulation type, and mounting configuration.

The selection between these parts should be based on the following factors:

Product Status: Part 11869 is active and currently in production, ensuring long-term availability and supply chain reliability. Part 11578 is obsolete and subject to inventory depletion.

Regulatory Compliance: Part 11869 carries ROHS3 compliance certification, meeting current environmental and material restriction requirements. Part 11578 is not RoHS certified.

Packaging: Part 11869 is supplied in bulk packaging (50-piece packs), which may affect procurement quantities and storage requirements compared to the original part's packaging specification.

For new designs, maintenance applications, and production continuity, part 11869 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can part 11869 be used as a direct replacement for 11578 in existing applications?

A: Yes. Both parts are identical in wire gauge (18-20 AWG), gender (male), termination method (crimp), insulation type (fully insulated heat shrink), and mounting configuration (free hanging in-line). They are functionally equivalent for all electrical and mechanical applications.

Q: What is the difference between these two parts?

A: The primary differences are product status and compliance. Part 11869 is active and ROHS3 compliant, while 11578 is obsolete and not RoHS certified. Part 11869 is packaged in bulk (50-piece packs).

Q: Why is 11578 listed as obsolete?

A: Part 11578 has been discontinued by the manufacturer. Part 11869 is the active equivalent that replaces it in the product line.

Q: Does the bulk packaging of 11869 affect compatibility?

A: No. Packaging format does not affect the electrical or mechanical performance of the terminal. The bulk packaging is a supply and procurement consideration only.
