Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-126-01-TM-SV-P is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header, cuttable design with male pin contacts
• Position Count & Row Configuration: 26 positions in single-row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting Technology: Surface mount termination with solder connection
• Mechanical Dimensions: Contact length (0.230"), insulation height (0.100"), and square contact shape
• Material & Finish Specifications: Phosphor bronze contacts with tin finish on both mating and post surfaces; LCP insulation
• Environmental & Compliance Requirements: Operating temperature range -55°C to 105°C, UL94 V-0 flammability rating, ROHS3 compliance

The substitute part TSM-126-01-T-SV-P matches all critical parameters and belongs to the same TSM series from Samtec Inc., differing only in fastening mechanism designation within the part number nomenclature while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the TSM-126-01-TM-SV-P and TSM-126-01-T-SV-P are active products from Samtec Inc. with identical ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and supply chain requirements, as both meet all specified electrical, mechanical, and environmental parameters. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during manufacturing. Both parts are suitable for applications requiring industrial temperature operation from -55°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can TSM-126-01-T-SV-P be used as a direct replacement for TSM-126-01-TM-SV-P?

A: Yes. Both parts share identical specifications across all critical parameters including connector type, position count, pitch, mounting method, contact materials, and environmental ratings. The part numbers differ only in fastening mechanism designation, but both maintain functional equivalence for board-to-board and cable interconnection applications.

Q: Are there any differences in mechanical compatibility?

A: No. Both parts feature identical mating pitch (0.100"), contact length (0.230"), insulation height (0.100"), and contact shape (square). They are mechanically interchangeable in PCB layouts and mating interface designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TSM-126-01-TM-SV-P and TSM-126-01-T-SV-P are ROHS3 compliant and carry UL94 V-0 flammability certification. Both have MSL rating of 1 (Unlimited), indicating equivalent moisture sensitivity characteristics.

Q: What is the significance of the part number difference between TM and T designations?

A: The difference in part number nomenclature reflects fastening mechanism variations within the TSM series. Both variants maintain identical electrical and mechanical specifications for the 26-position, 2.54mm pitch header configuration.

Q: Are packaging and inventory considerations the same?

A: Both parts are supplied in tube packaging. Inventory levels may vary between the two part numbers, making either option viable depending on current stock availability and supply chain timing requirements.
