Parameter Comparison

Engineering Selection Recommendations

The 2-644488-3 serves as the direct substitute for the obsolete 644488-3 connector. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch spacing, position count, voltage rating, temperature range, and physical dimensions.

The primary advantages of selecting the 2-644488-3 substitute are:

Product Status: The substitute carries active product status, ensuring ongoing availability and manufacturing support. The main part 644488-3 is obsolete and subject to supply discontinuation.

Regulatory Compliance: The 2-644488-3 achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The main part carries RoHS non-compliant status.

Contact Finish: The substitute employs pure tin contact finish on both mating and post surfaces, compared to the tin-lead finish of the main part. Both finishes maintain functional compatibility and electrical performance within the specified operating parameters.

Inventory Availability: The substitute part maintains significantly higher inventory levels (4993 pieces) compared to the main part (1010 pieces), supporting production continuity and lead-time reduction.

Selection of the 2-644488-3 substitute is appropriate for all applications currently utilizing the 644488-3, with no functional limitations or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 2-644488-3 substitute be used as a direct replacement for the 644488-3 in existing designs?

A: Yes. The 2-644488-3 maintains identical electrical and mechanical specifications across all critical parameters. Pitch spacing, position count, voltage rating, temperature range, mounting configuration, and physical dimensions are equivalent. Direct substitution is supported without design modification.

Q: What is the difference between the tin-lead finish on the 644488-3 and the tin finish on the 2-644488-3?

A: The main part uses tin-lead contact finish, while the substitute uses pure tin finish. Both finishes provide equivalent electrical performance and corrosion resistance within the specified operating parameters. The tin finish on the substitute reflects current manufacturing standards and RoHS compliance requirements.

Q: Why is the 644488-3 listed as obsolete?

A: The 644488-3 carries obsolete product status, indicating that TE Connectivity has transitioned production to the 2-644488-3 variant. The substitute part maintains full functional equivalence while offering improved regulatory compliance and active manufacturing support.

Q: Does the RoHS3 compliance of the 2-644488-3 affect compatibility with existing applications?

A: No. RoHS3 compliance indicates adherence to environmental and hazardous substance restrictions. This compliance status does not alter electrical or mechanical performance. The substitute is fully compatible with applications designed for the main part.

Q: Are there packaging differences between the 644488-3 and 2-644488-3?

A: The main part packaging is not specified in available documentation. The substitute part 2-644488-3 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the moisture sensitivity level for both parts?

A: Both the 644488-3 and 2-644488-3 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special environmental controls.

Q: Can the 2-644488-3 be used in applications requiring RoHS compliance?

A: Yes. The 2-644488-3 achieves ROHS3 compliance and is suitable for applications with RoHS requirements. The main part 644488-3 does not meet RoHS compliance standards.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 644488-3 and 2-644488-3 operate across the identical temperature range of -55°C to 105°C. Thermal performance and reliability are equivalent across this range.
