TSS-136-01-T-D Equivalent & Substitute Parts

Part Overview

The TSS-136-01-T-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 72-position vertical header operates across industrial temperature ranges and meets RoHS3 compliance requirements. The part is currently active in production with 715 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where form factor and performance characteristics remain consistent.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 72 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding Design: Shrouded 4-wall construction
• Contact Dimensions: Mating length 0.250", post length 0.115", overall length 0.480"
• Insulation Geometry: 0.350" insulation height
• Material & Finish: Phosphor bronze contacts with tin finish, PBT insulation
• Environmental Compliance: Operating temperature -55°C to 105°C, UL94 V-0, RoHS3 compliant

The TST-136-01-T-D meets all these criteria and is classified as an equivalent substitute. The primary distinction lies in the connector style designation (TST series versus TSS series) and insulation material composition (glass-filled PBT in the substitute).

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-136-01-T-D and TST-136-01-T-D are active production components from Samtec Inc. with identical electrical and mechanical specifications across all critical parameters. Both parts maintain RoHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity classification.

The TST-136-01-T-D substitute incorporates glass-filled PBT insulation material, which provides enhanced mechanical and thermal properties compared to standard PBT. The substitute also specifies a current rating of 3.4A per contact, whereas the main part does not provide this specification.

Selection between these parts depends on application requirements for insulation material composition and documented current handling capacity. Both parts are suitable for through-hole board-to-board and cable interconnect applications operating within the -55°C to 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can TST-136-01-T-D replace TSS-136-01-T-D in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting method, shrouding design, and contact dimensions. The primary difference is the insulation material composition in the substitute part, which uses glass-filled PBT instead of standard PBT.

Q: What is the significance of glass-filled PBT insulation in the substitute part?

A: Glass-filled PBT provides improved mechanical strength, dimensional stability, and thermal performance compared to unfilled PBT. This material enhancement does not affect electrical or mechanical compatibility with mating connectors or PCB footprints.

Q: Are there differences in operating temperature ranges?

A: No. Both parts operate across the identical temperature range of -55°C to 105°C and maintain UL94 V-0 flammability rating across this range.

Q: Does the substitute part's current rating of 3.4A per contact affect compatibility?

A: The substitute part provides a documented current specification that the main part does not. This specification indicates the substitute's electrical capacity but does not create incompatibility. Applications requiring current handling verification should reference the substitute's documented rating.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TSS-136-01-T-D and TST-136-01-T-D are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the difference between TSS and TST series designations?

A: The series designation reflects Samtec's product line categorization. Both series employ identical connector architecture, contact configuration, and performance specifications for this 72-position header application.
