Parameter Comparison

Engineering Selection Recommendations

The 3-641208-9 is the direct equivalent substitute for the obsolete 641208-9. Both parts are manufactured by TE Connectivity AMP Connectors within the MTA-156 series and maintain identical electrical, mechanical, and dimensional specifications across all critical parameters.

Product Status Consideration: The 641208-9 is classified as obsolete, while the 3-641208-9 maintains active product status. This distinction is significant for long-term component sourcing and supply chain continuity.

Compliance Certification: The substitute part 3-641208-9 is ROHS3 compliant, whereas the main part 641208-9 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 3-641208-9 is the appropriate selection.

Contact Finish Specification: The primary technical distinction between the two parts is the post contact finish. The 641208-9 specifies Tin-Lead finish, while the 3-641208-9 specifies Tin finish. Both finishes are functionally equivalent for solder termination applications and maintain the same mating contact finish (Gold) and thickness specifications.

Packaging: The 3-641208-9 is supplied in Bulk packaging, whereas packaging information for the 641208-9 is not specified. Both parts are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Are the 641208-9 and 3-641208-9 mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including mounting type (through hole), connector configuration (9-position, single-row header), pitch spacing (0.156"), contact dimensions, and insulation geometry. Direct substitution is supported without design modification.

Q: What is the significance of the different contact finish specifications (Tin-Lead versus Tin)?

A: Both finishes are suitable for solder termination applications. The Tin finish in the 3-641208-9 is a lead-free alternative to the Tin-Lead finish in the 641208-9. This change reflects modern manufacturing standards and RoHS compliance requirements. Functional performance in solder joint formation is equivalent.

Q: Why is the 641208-9 classified as obsolete?

A: The 641208-9 is an older product variant. The 3-641208-9 represents the current active production equivalent, incorporating modern compliance certifications (ROHS3) and manufacturing standards while maintaining full electrical and mechanical compatibility.

Q: Can the 3-641208-9 be used in applications originally designed for the 641208-9?

A: Yes. The 3-641208-9 is a direct functional equivalent. All electrical parameters (voltage rating, operating temperature, current capacity), mechanical specifications (pitch, contact configuration, mounting type), and dimensional characteristics are identical. No circuit design or PCB layout modifications are required.

Q: What is the difference in RoHS compliance between these parts?

A: The 641208-9 is RoHS non-compliant, while the 3-641208-9 is ROHS3 compliant. ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive, which restricts the use of specific hazardous materials in electrical and electronic equipment. For applications subject to RoHS regulations or customer specifications requiring RoHS compliance, the 3-641208-9 is the required selection.

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

A: No. Both parts maintain identical electrical specifications: 600VAC voltage rating, -55°C to 105°C operating temperature range, identical contact materials (copper alloy), identical mating contact finish (gold, 30.0µin thickness), and equivalent current-carrying capacity based on wire gauge. Electrical performance is fully equivalent.

Q: What packaging options are available for the substitute part?

A: The 3-641208-9 is supplied in Bulk packaging. Current inventory availability is 1823 pieces in new original condition.
