Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-136-01-G-D-01 is determined by strict alignment of the following critical parameters:

Connector geometry and mating interface: 72 positions, 2 rows, 0.100" (2.54mm) pitch, and 0.100" (2.54mm) row spacing must remain constant to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.

Contact specifications: Male pin contact type, phosphor bronze material, and gold mating finish are required for proper signal integrity and durability.

Mounting and termination: Through-hole solder termination and push-pull fastening type must be preserved.

Environmental and compliance ratings: Operating temperature range of -55°C to 125°C, UL94 V-0 flammability rating, and ROHS3 compliance are mandatory for equivalent substitution.

The TST-136-01-G-D-01 qualifies as a direct substitute based on these parameters. While it belongs to the TST series rather than the TSS series, it maintains identical connector geometry, contact specifications, mounting type, and environmental ratings. The primary distinction is the connector style designation (Board to Cable/Wire versus Board to Board or Cable) and insulation material composition (glass-filled PBT), which do not affect electrical or mechanical compatibility in applications where either style is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-136-01-G-D-01 and TST-136-01-G-D-01 are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application requirements and inventory availability.

The TSS-136-01-G-D-01 is designated for board-to-board or cable applications, while the TST-136-01-G-D-01 is designated for board-to-cable/wire applications. The TST variant features glass-filled PBT insulation material, which provides enhanced mechanical strength compared to standard PBT. Both parts share identical electrical and mechanical specifications, including contact geometry, pitch, operating temperature range, and fastening mechanism.

Current inventory levels show 971 units of TST-136-01-G-D-01 available compared to 713 units of TSS-136-01-G-D-01. Selection should prioritize application compatibility with the connector style designation while considering supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can TST-136-01-G-D-01 be used as a direct replacement for TSS-136-01-G-D-01?

A: Yes, provided the application accepts board-to-cable/wire connector style. Both parts maintain identical 72-position, 2-row geometry with 0.100" (2.54mm) pitch, male pin contacts, gold-plated phosphor bronze materials, and operating temperature range of -55°C to 125°C. The primary difference is the connector style designation and insulation material composition (glass-filled PBT versus standard PBT).

Q: What is the significance of the glass-filled PBT insulation in the TST-136-01-G-D-01?

A: Glass-filled PBT provides enhanced mechanical strength and dimensional stability compared to standard PBT. This material composition does not affect electrical performance or environmental compliance ratings. Selection should be based on mechanical durability requirements of the specific application.

Q: Are both parts RoHS compliant?

A: Yes, both TSS-136-01-G-D-01 and TST-136-01-G-D-01 are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

Q: What is the difference between board-to-board and board-to-cable/wire connector styles?

A: Board-to-board connectors (TSS series) are designed for mating two PCBs together. Board-to-cable/wire connectors (TST series) are designed for mating a PCB with external cable or wire harnesses. The mechanical and electrical specifications remain identical; the distinction reflects intended application context.

Q: Do both parts support the same operating temperature range?

A: Yes, both parts operate across -55°C to 125°C and maintain identical moisture sensitivity level (MSL 1, Unlimited), ensuring compatibility in equivalent thermal environments.

Q: What does the keying slot feature provide?

A: The keying slot prevents incorrect mating orientation between connector header and mating connector, ensuring proper alignment and contact engagement.
