Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-117-01-G-D-LL is determined by strict alignment of the following critical parameters:

• Connector positioning and pitch: 34 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
• Physical mounting and termination: Through-hole mounting with kinked pin solder termination
• Electrical and contact specifications: Male pin contact type, gold-plated mating surface, phosphor bronze material
• Environmental and compliance ratings: Operating temperature -55°C to 125°C, UL94 V-0 flammability, ROHS3 compliance, MSL 1

The TST-117-01-G-D-LL qualifies as a substitute part because it maintains identical specifications across all critical substitution parameters. Variations in secondary attributes such as insulation material composition (glass-filled PBT) and application classification (board-to-cable/wire versus board-to-board) do not affect functional interchangeability within the defined electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both TSS-117-01-G-D-LL and TST-117-01-G-D-LL maintain active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific requirements and supply availability. The TST-117-01-G-D-LL incorporates glass-filled PBT insulation material, which may provide enhanced mechanical properties in specific thermal or mechanical stress environments. Both parts satisfy identical electrical, thermal, and environmental operating specifications. Component selection should account for PCB layout compatibility, connector mating interface requirements, and inventory availability at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Can TST-117-01-G-D-LL be used as a direct replacement for TSS-117-01-G-D-LL?

A: Yes. Both parts share identical connector positioning (34 positions, 2 rows), pitch specifications (0.100" mating and row spacing), contact geometry, termination method, and operating temperature range. The glass-filled PBT insulation in the TST variant does not affect electrical or mechanical interchangeability.

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

A: The series designation reflects the base product family within Samtec's Flex Stack connector line. TSS-117 and TST-117 represent distinct product lines within the same connector category, with the TST variant incorporating glass-filled polybutylene terephthalate insulation material.

Q: Are there any application restrictions between these two parts?

A: The TSS-117-01-G-D-LL is specified for board-to-board or cable applications, while the TST-117-01-G-D-LL is specified for board-to-cable/wire applications. Both support identical electrical and mechanical specifications. Application suitability depends on the specific mating interface requirements of the design.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both TSS-117-01-G-D-LL and TST-117-01-G-D-LL are ROHS3 compliant, carry UL94 V-0 flammability ratings, and maintain MSL 1 (unlimited) moisture sensitivity levels.

Q: What is the significance of the glass-filled PBT insulation in the TST variant?

A: Glass-filled polybutylene terephthalate provides enhanced mechanical strength and dimensional stability compared to unfilled PBT. This material composition does not alter electrical performance or environmental operating specifications.

Q: Are there current rating differences between these parts?

A: The TST-117-01-G-D-LL specifies a current rating of 3.4A per contact. The TSS-117-01-G-D-LL does not provide a specified current rating in the available documentation. Design applications requiring explicit current rating specifications should reference the TST-117-01-G-D-LL.
