Parameter Comparison

Engineering Selection Recommendations

The part 2-644489-5 is the direct equivalent substitute for the obsolete TE Connectivity 644489-5. Selection of the substitute part is based on the following engineering criteria:

Product Status: The original part 644489-5 carries an obsolete designation, limiting long-term procurement viability. The substitute part 2-644489-5 maintains active product status, ensuring continued availability and manufacturing support.

Regulatory Compliance: The substitute part 2-644489-5 is ROHS3 compliant, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements.

Functional Equivalence: All electrical and mechanical parameters remain identical between the main part and substitute, including connector type, position count, pitch spacing, mounting configuration, voltage rating, and operating temperature range.

Material Specification Variation: The substitute part specifies Tin contact finish on the post termination, compared to Tin-Lead on the original part. This represents a compatible variation consistent with modern lead-free manufacturing standards and does not affect electrical or mechanical compatibility.

Packaging Consideration: The substitute part is supplied in bulk packaging, whereas the original part packaging specification is not provided. Bulk packaging does not affect functional performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2-644489-5 be used as a direct replacement for the 644489-5 in existing designs?

A: Yes. The 2-644489-5 is a direct functional equivalent. All critical electrical and mechanical parameters are identical, including pitch spacing (0.100"), position count (5), mounting type (through-hole right-angle), voltage rating (250VAC), and operating temperature range (-55°C to 105°C). The connector will mate with existing cable assemblies and PCB layouts designed for the original part.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: The original part specifies Tin-Lead post finish, while the substitute specifies Tin post finish. This difference reflects the transition to lead-free manufacturing standards. Both finishes provide equivalent solderability and electrical performance for through-hole solder termination applications. The Tin finish on the substitute part is compatible with modern lead-free solder processes.

Q: Why is the substitute part ROHS3 compliant while the original is not?

A: The original part 644489-5 was manufactured under earlier standards that permitted lead-based materials. The substitute part 2-644489-5 was manufactured to current RoHS3 compliance standards, which restrict hazardous substances including lead. For applications subject to RoHS regulations or environmental compliance requirements, the substitute part is the appropriate selection.

Q: Are there any performance differences between the two parts?

A: No performance differences exist. Both parts maintain identical electrical ratings (250VAC), thermal operating range (-55°C to 105°C), contact materials (copper alloy), insulation materials (polyester), and flammability ratings (UL94 V-0). The parts are functionally interchangeable.

Q: What is the difference between the packaging specifications?

A: The original part packaging specification is not provided in the technical data. The substitute part is supplied in bulk packaging. Packaging format does not affect connector performance, electrical characteristics, or mechanical compatibility. Bulk packaging is standard for active production parts.

Q: Is the 2-644489-5 available in the same quantities as the original part?

A: The substitute part 2-644489-5 has significantly higher inventory availability (3722 pieces in stock) compared to the original part (954 pieces in stock). The active product status of the substitute ensures continued manufacturing and procurement support.

Q: Can the 2-644489-5 be used in applications requiring RoHS compliance?

A: Yes. The 2-644489-5 is ROHS3 compliant and is suitable for all applications subject to RoHS regulations. The original part 644489-5 is RoHS non-compliant and should not be used in RoHS-regulated applications.
