Engineering Selection Recommendations

The 3-641227-2 is a direct functional and mechanical equivalent to the 641227-2. Both parts share identical electrical and physical specifications across all critical parameters including connector geometry, contact configuration, termination method, and material composition.

Product Status Consideration: The 641227-2 is classified as Obsolete, while the 3-641227-2 maintains Active product status. For new designs, ongoing production, or long-term supply chain planning, the 3-641227-2 is the appropriate selection. Both parts satisfy identical RoHS and REACH compliance requirements.

Packaging Difference: The 3-641227-2 is supplied in Bulk packaging, whereas the main part number does not specify a packaging configuration. This distinction affects procurement and inventory management but does not impact connector performance or compatibility.

Compliance Alignment: Both parts are ROHS3/RoHS Compliant, REACH Unaffected, and classified under ECCN EAR99. Regulatory and environmental requirements are satisfied by either part.

Frequently Asked Questions (FAQ)

Q: Can the 3-641227-2 be used as a direct replacement for the 641227-2 in existing assemblies?

A: Yes. The 3-641227-2 is a direct substitute. All electrical, mechanical, and dimensional specifications are identical. The connector will interface with mating components, cable assemblies, and PCB layouts designed for the 641227-2 without modification.

Q: What is the significance of the Obsolete status on the 641227-2?

A: Obsolete status indicates that the 641227-2 is no longer in active production. The 3-641227-2, with Active status, represents the current production equivalent and is the recommended selection for new procurement and design activities.

Q: Are there differences in RoHS compliance between these parts?

A: The 641227-2 is ROHS3 Compliant, while the 3-641227-2 is RoHS Compliant. Both designations confirm compliance with lead-free and hazardous substance restrictions. The parts are functionally equivalent from a regulatory perspective.

Q: Does the Bulk packaging of the 3-641227-2 affect its electrical performance?

A: No. Packaging configuration is a supply chain and logistics parameter only. It does not alter the connector's electrical characteristics, contact resistance, or mechanical performance.

Q: What parameters must remain constant for substitution eligibility?

A: Connector type, contact type, position count, pitch, row configuration, mounting method, fastening mechanism, termination type, wire gauge, contact finish, and finish thickness must all match exactly. The 3-641227-2 satisfies all these requirements.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the 641227-2 and 3-641227-2 support discrete or ribbon cable configurations with 18 AWG wire gauge through IDC termination.
