Parameter Comparison

Engineering Selection Recommendations

Both the 641119-7 and 3-641119-7 are classified as Active product status from TE Connectivity AMP Connectors and maintain full compliance with RoHS regulations. The primary distinction between these parts is the contact finish on the post termination: the 641119-7 features tin-lead plating, while the 3-641119-7 features tin plating. Both configurations maintain equivalent electrical performance, mechanical compatibility, and thermal operating ranges.

The 641119-7 with tin-lead post finish is suitable for applications where lead-based solder processes are employed. The 3-641119-7 with tin post finish aligns with lead-free manufacturing environments and RoHS3 compliance requirements. Selection between these parts depends on the specific soldering process and regulatory requirements of the end application.

Both parts maintain identical mating pitch (0.156"), contact geometry, shrouding configuration, and voltage/temperature ratings, ensuring direct substitution capability in circuit board designs without modification to PCB layouts or mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the 641119-7 and 3-641119-7 be used interchangeably in the same circuit board design?
