Engineering Selection Recommendations

The part 3-641237-4 is a direct functional equivalent to 641237-4 across all electrical and mechanical specifications. The substitute part maintains identical contact configuration, termination method, wire gauge compatibility, and finish specifications.

Product Status Consideration: The main part 641237-4 carries an obsolete designation, while the substitute 3-641237-4 is classified as active. For new designs, ongoing production, or long-term system support, the active substitute part is the appropriate selection.

Compliance Status: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current regulatory requirements and environmental specifications.

Packaging Difference: The substitute part is supplied in bulk packaging, which may affect procurement quantities and storage requirements compared to the original part specification.

Frequently Asked Questions (FAQ)

Q: Can 3-641237-4 be used as a direct replacement for 641237-4 in existing assemblies?

A: Yes. The 3-641237-4 maintains identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, termination method, wire gauge, and contact finish. The parts are functionally interchangeable.

Q: What is the primary reason for substitution?

A: The original part 641237-4 is classified as obsolete. The substitute 3-641237-4 is an active product from the same manufacturer and series, providing continued availability and supply chain continuity.

Q: Are there any differences in contact performance between these parts?

A: No. Both parts feature identical gold contact finish at 30.0µin (0.76µm) thickness, female socket contact type, and IDC termination design. Contact performance specifications are equivalent.

Q: Does the packaging difference affect connector functionality?

A: No. The packaging difference (bulk for the substitute versus unspecified for the main part) affects procurement and storage logistics only. The connector itself maintains identical form, fit, and function.

Q: Are both parts RoHS compliant?

A: Yes. Both 641237-4 and 3-641237-4 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What wire gauges are compatible with these connectors?

A: Both parts are specified for 22 AWG wire. The IDC termination method accommodates discrete or ribbon cable configurations at this gauge.

Q: Is the connector suitable for both in-line and right-angle mounting?

A: Yes. Both parts support free-hanging mounting in both in-line and right-angle orientations.
