Engineering Selection Recommendations

The 641150-4 is classified as obsolete. The direct substitute part 3-641150-4 provides functional equivalence across all electrical and mechanical parameters while offering the advantage of active product status.

Key Differentiation Factors:

Product Status: The 3-641150-4 is actively manufactured and supported, whereas the 641150-4 is obsolete. This ensures long-term availability and supply chain continuity.
RoHS Compliance: The 3-641150-4 is RoHS Compliant, meeting current environmental and regulatory requirements. The 641150-4 is RoHS non-compliant, which may present restrictions in certain applications or markets.
Packaging: The 3-641150-4 is supplied in bulk packaging, whereas the 641150-4 packaging specification is not provided.
Electrical & Mechanical Equivalence: Both parts are identical in connector type, contact configuration, pitch, termination method, wire gauge, contact finish, and all other functional parameters.

For new designs or system replacements, the 3-641150-4 is the appropriate selection. For legacy system maintenance where the original 641150-4 is specified, the 3-641150-4 provides direct functional substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 3-641150-4 be used as a direct replacement for the 641150-4 in existing assemblies?

A: Yes. The 3-641150-4 is functionally equivalent to the 641150-4 across all electrical and mechanical parameters, including connector type, contact configuration, pitch, termination method, wire gauge, and contact finish. Direct substitution is supported without design modification.

Q: What is the significance of the product status difference between these parts?

A: The 641150-4 is classified as obsolete, indicating it is no longer actively manufactured. The 3-641150-4 is active, ensuring ongoing availability, supply chain support, and manufacturer technical support. For new designs or long-term system maintenance, the active part is the appropriate selection.

Q: Does the RoHS compliance difference affect substitution?

A: The 3-641150-4 is RoHS Compliant, meeting current environmental regulations. The 641150-4 is RoHS non-compliant. If your application or market requires RoHS compliance, the 3-641150-4 is the required selection. Both parts are otherwise electrically and mechanically equivalent.

Q: Are the contact finish specifications identical between these parts?

A: Yes. Both parts feature gold-plated contacts with a finish thickness of 15.0µin (0.38µm), ensuring equivalent electrical performance and contact reliability.

Q: What wire gauges and termination methods are supported by these connectors?

A: Both connectors support 22 AWG wire with IDC (Insulation Displacement Contact) termination. They accommodate discrete or ribbon cable configurations.

Q: Is the pitch specification the same for both parts?

A: Yes. Both the 641150-4 and 3-641150-4 feature a 0.156" (3.96mm) pitch in a single-row, 4-position configuration, ensuring mechanical and electrical interchangeability.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.
