Engineering Selection Recommendations

The substitute part 2-644861-6 is the direct equivalent for the obsolete 644861-6. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 644861-6 carries an obsolete designation, limiting availability for new procurement. The substitute part 2-644861-6 maintains active product status, ensuring continued supply chain access and manufacturer support.

Compliance Certifications: The substitute part 2-644861-6 achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the substitute part satisfies mandatory compliance obligations. The substitute part also carries REACH Unaffected status, providing clarity on chemical substance compliance.

Contact Finish Specification: The substitute part features a Tin contact finish on both mating and post surfaces, replacing the Tin-Lead finish of the main part. This transition aligns with industry-wide lead elimination initiatives and regulatory restrictions on lead-containing materials.

Electrical and Mechanical Equivalence: All electrical parameters, mechanical dimensions, and functional characteristics remain identical between the main part and substitute part. Direct pin-for-pin and footprint compatibility is maintained.

Frequently Asked Questions (FAQ)

Q: Can the 2-644861-6 substitute directly replace the 644861-6 in existing designs?

A: Yes. The 2-644861-6 maintains full electrical and mechanical equivalence to the 644861-6. Pin count, pitch, mounting configuration, and contact geometry are identical. Direct substitution in PCB layouts and cable assemblies is supported without design modification.

Q: What is the primary difference between the 644861-6 and 2-644861-6?

A: The primary differences are product status, compliance certifications, and contact finish. The 644861-6 is obsolete with RoHS non-compliant status and Tin-Lead contact finish. The 2-644861-6 is active, ROHS3 compliant, and features Tin contact finish.

Q: Does the Tin contact finish of the 2-644861-6 affect electrical performance compared to the Tin-Lead finish of the 644861-6?

A: No. Both contact finishes meet the 250VAC voltage rating and support the same current-carrying capacity based on wire gauge. Electrical performance characteristics remain equivalent.

Q: Is the 2-644861-6 suitable for applications requiring RoHS compliance?

A: Yes. The 2-644861-6 carries ROHS3 compliance certification, satisfying RoHS regulatory requirements. The original 644861-6 is RoHS non-compliant.

Q: What is the packaging difference between the two parts?

A: The main part 644861-6 packaging is not specified in available documentation. The substitute part 2-644861-6 is supplied in Bulk packaging.

Q: Are there any temperature or voltage limitations when using the 2-644861-6 as a substitute?
