Substitute Part Grouping Explanation

Substitution eligibility for the TSM-128-01-L-DV is determined by strict equivalence across the following critical parameters:

  • Position Count & Row Configuration: 56 positions in 2-row arrangement
  • Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
  • Contact Characteristics: Male pin contact type with phosphor bronze material
  • Mounting & Termination: Surface mount with solder termination
  • Electrical & Environmental Ratings: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating
  • Compliance Standards: ROHS3 compliance and MSL Level 1

The substitute part TSM-128-01-L-DV-A maintains identical specifications across all critical parameters, with the addition of a board guide feature. This feature does not alter the core electrical or mechanical compatibility of the connector.

Engineering Selection Recommendations

Both TSM-128-01-L-DV and TSM-128-01-L-DV-A are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all critical electrical and mechanical parameters. The TSM-128-01-L-DV-A includes a board guide feature that provides enhanced mechanical alignment during assembly without affecting electrical performance or environmental ratings.

Selection between these parts should be based on PCB design requirements. If board guide alignment assistance is beneficial for manufacturing processes, the TSM-128-01-L-DV-A is the appropriate choice. If board guide features are not required, either part is suitable. Both parts maintain identical operating temperature ranges, compliance certifications, and contact specifications.

Frequently Asked Questions (FAQ)

Q: Are TSM-128-01-L-DV and TSM-128-01-L-DV-A electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including contact material (phosphor bronze), contact finish (gold), operating temperature range (-55°C ~ 125°C), and all mating parameters (56 positions, 0.100" pitch, 2-row configuration).

Q: What is the functional difference between these two parts?

A: The TSM-128-01-L-DV-A includes a board guide feature. This is a mechanical enhancement that aids in connector alignment during assembly. The board guide does not alter electrical performance or environmental ratings.

Q: Can I use TSM-128-01-L-DV-A as a direct replacement for TSM-128-01-L-DV in existing designs?

A: Yes, provided your PCB layout accommodates the board guide feature. The connector footprint and mating interface remain identical. Verify that the board guide does not interfere with adjacent components or PCB features.

Q: Are both parts RoHS compliant?

A: Yes. Both TSM-128-01-L-DV and TSM-128-01-L-DV-A are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity).

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 125°C, suitable for industrial and commercial applications.

Q: Are these parts suitable for high-reliability applications?

A: Both parts meet UL94 V-0 flammability standards and maintain consistent performance across the specified operating temperature range. Compliance certifications support use in standard industrial applications.
