TST-136-01-S-D Equivalent & Substitute Parts

Part Overview

The TST-136-01-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 72-position, 2-row connector operates within the Flex Stack TST series and is classified as Active product status. The connector features shrouded 4-wall construction with push-pull fastening, making it suitable for board-to-cable/wire interconnections. Identifying equivalent and substitute parts becomes necessary when managing inventory constraints, ensuring supply chain continuity, or matching specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type & Contact Configuration: Header with Male Pin contacts
• Position Count & Row Configuration: 72 positions arranged in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding & Fastening: Shrouded 4-wall construction with push-pull fastening
• Contact Material & Finish: Phosphor Bronze with gold mating finish
• Electrical Performance: 3.4A per contact current rating
• Environmental Compliance: Operating temperature range -55°C ~ 125°C, ROHS3 Compliant, UL94 V-0 flammability rating

The TSS-136-01-S-D qualifies as a substitute part because it maintains identical specifications across all critical parameters. Both parts belong to the Samtec Flex Stack connector family, share the same contact configuration, pitch, position count, and electrical ratings. The primary distinction lies in series designation (TST versus TSS) and minor insulation material specification variance (PBT Glass Filled versus PBT standard), which do not affect functional interchangeability within the defined parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TST-136-01-S-D and TSS-136-01-S-D maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally interchangeable across all critical electrical and mechanical parameters. Selection between these parts should be based on inventory availability and supply chain considerations. The TST-136-01-S-D currently maintains 975 pieces in stock, while the TSS-136-01-S-D maintains 689 pieces. Both parts satisfy identical compliance requirements and environmental operating specifications. The minor variance in insulation material specification (glass-filled versus standard PBT) does not affect functional performance within the defined parameter constraints.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts maintain identical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, contact material, and electrical ratings. The series designation difference (TST versus TSS) reflects internal Samtec product line organization and does not affect functional interchangeability.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: connector type (Header), contact type (Male Pin), position count (72), row configuration (2 rows), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (Through Hole), shrouding (Shrouded - 4 Wall), fastening type (Push-Pull), contact material (Phosphor Bronze), contact finish (Gold mating/Tin post), and operating temperature range (-55°C ~ 125°C).

Q: Are there any differences in insulation material between these parts?

A: The TST-136-01-S-D specifies Polybutylene Terephthalate (PBT) Glass Filled insulation, while the TSS-136-01-S-D specifies standard Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and maintain identical electrical and mechanical performance within the defined operating parameters.

Q: What is the current rating for these connectors?

A: The TST-136-01-S-D is rated at 3.4A per contact. The TSS-136-01-S-D does not specify a current rating in the provided data; however, both parts share identical contact material, geometry, and finish specifications, indicating equivalent current-carrying capacity.

Q: Are both parts RoHS compliant?

A: Yes. Both TST-136-01-S-D and TSS-136-01-S-D are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Q: What is the difference between board-to-cable/wire and board-to-board style designations?

A: The TST-136-01-S-D is designated for board-to-cable/wire applications, while the TSS-136-01-S-D is designated for board-to-board or cable applications. Both parts feature identical mechanical and electrical specifications; the style designation reflects intended application context rather than physical or functional differences.
