Parameter Comparison

Engineering Selection Recommendations

The 2-644489-6 serves as the direct equivalent substitute for the obsolete 644489-6. Both components are manufactured by TE Connectivity AMP Connectors within the MTA-100 series and maintain identical electrical and mechanical specifications across all critical parameters.

Primary Substitution Basis:

The 2-644489-6 provides complete functional equivalence with the following advantages:

1. Product Status: The substitute part carries an active product status, ensuring ongoing availability and manufacturing support, whereas the 644489-6 is obsolete.

2. Regulatory Compliance: The 2-644489-6 is ROHS3 compliant and REACH unaffected, compared to the non-compliant status of the original part. This compliance improvement aligns with current environmental and regulatory requirements for electronic components.

3. Contact Finish - Post: The substitute utilizes tin finish on the post contact, compared to tin-lead finish on the original part. Both finishes are functionally equivalent for solder termination applications and provide equivalent electrical performance.

4. Inventory Availability: The 2-644489-6 maintains higher inventory levels (2818 pieces) compared to the 644489-6 (1102 pieces), supporting procurement continuity.

5. Packaging: The substitute is supplied in bulk packaging, offering flexibility for production requirements.

All other electrical, mechanical, and material specifications remain identical between the two parts, confirming direct interchangeability in existing designs without modification to PCB layouts, mating connectors, or assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the 2-644489-6 be used as a direct replacement for the 644489-6 in existing designs?

A: Yes. The 2-644489-6 maintains identical electrical and mechanical specifications across all critical parameters including pitch, number of positions, contact dimensions, operating temperature range, and voltage rating. No design modifications are required for direct substitution.

Q: What is the difference between the tin-lead finish on the 644489-6 and the tin finish on the 2-644489-6?

A: Both finishes are functionally equivalent for solder termination applications. The tin finish on the 2-644489-6 reflects the shift away from lead-containing materials in modern manufacturing, consistent with ROHS3 compliance requirements.

Q: Why is the 644489-6 listed as obsolete?

A: The 644489-6 has been superseded by the 2-644489-6 within the manufacturer's product line. The substitute part offers improved regulatory compliance and active production status while maintaining complete functional equivalence.

Q: Are there any compatibility issues with mating connectors?

A: No. The 2-644489-6 maintains identical mating contact dimensions (0.200" mating length), pitch spacing (0.100"), and shrouding configuration (shrouded 4-wall). Existing mating connectors designed for the 644489-6 are fully compatible with the 2-644489-6.

Q: What is the significance of the ROHS3 compliance on the 2-644489-6?

A: ROHS3 compliance indicates the part meets current Restriction of Hazardous Substances regulations, restricting the use of lead and other hazardous materials. This compliance status is required for many applications and markets, particularly in consumer electronics and regulated industries.

Q: Does the packaging difference between the two parts affect compatibility?

A: No. The packaging difference (unspecified for 644489-6 versus bulk for 2-644489-6) affects only procurement and handling procedures, not electrical or mechanical compatibility. The connector specifications remain identical.

Q: Can the 2-644489-6 be used in applications requiring REACH compliance?

A: Yes. The 2-644489-6 is listed as REACH unaffected, indicating it complies with REACH regulations. The original 644489-6 has undefined REACH status, making the substitute the preferred choice for applications with REACH requirements.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -55°C to 105°C, ensuring equivalent thermal performance in all operating environments.
