Substitute Part Grouping Explanation
Substitution eligibility for the TMMH-125-01-F-DV is determined by strict equivalence across the following critical parameters:
Connector pitch (0.079" / 2.00mm mating pitch), position count (50 positions), row configuration (2 rows), row spacing (0.079" / 2.00mm), contact type (male pin), mounting method (surface mount), termination type (solder), contact length (0.126" / 3.20mm mating), insulation height (0.079" / 2.00mm), contact shape (square), contact materials (phosphor bronze), insulation material (liquid crystal polymer), and operating temperature range (-55°C ~ 125°C).
The identified substitute part maintains identical specifications across all these parameters, ensuring direct functional and mechanical compatibility in board-level applications.

Frequently Asked Questions (FAQ)
Q: Are TMMH-125-01-F-DV and TMMH-125-01-FM-DV directly interchangeable?
A: Yes. Both parts are functionally and mechanically equivalent across all specified parameters including pitch, position count, row configuration, contact geometry, materials, and operating temperature range. Direct substitution is supported in board-level applications.
Q: What determines substitution eligibility for TMMH series connectors?
A: Substitution is valid when mating pitch, number of positions, row count, row spacing, contact type, mounting method, termination type, contact length, insulation height, contact shape, contact materials, insulation material, and operating temperature range remain identical.
Q: Are there any compliance or certification differences between these parts?
A: No. Both parts carry identical RoHS3 compliance status, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification.
Q: What is the packaging format for these connectors?
A: Both parts are supplied in tube packaging format suitable for automated assembly processes.
Q: Can these connectors be cut to shorter lengths?
A: Yes. Both parts are designated as cuttable headers, allowing field modification to shorter position counts as required by application design.
