TSS-117-03-G-D Equivalent & Substitute Parts

Part Overview

The TSS-117-03-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 34-position, 2-row connector operates across the temperature range of -55°C to 125°C and features shrouded 4-wall construction with gold-plated contacts. The part is currently active in production with full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-117-03-G-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 34 positions in 2-row arrangement
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding Design: Shrouded 4-wall construction
• Contact Material & Finish: Phosphor bronze with gold plating on mating surfaces
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature Range: -55°C to 125°C
• Compliance Standards: UL94 V-0 flammability rating and ROHS3 compliance

The TST-117-03-G-D qualifies as a substitute based on matching all critical electrical and mechanical parameters. Differences in series designation (TST versus TSS) and connector style (Board to Cable/Wire versus Board to Board or Cable) do not affect functional compatibility when mating interface requirements are equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-117-03-G-D and TST-117-03-G-D are active products manufactured by Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all critical mating and mechanical parameters. Selection between these parts should be based on application-specific requirements regarding connector style designation and insulation material composition. The TST-117-03-G-D features glass-filled PBT insulation, which provides enhanced mechanical properties compared to standard PBT. Both parts maintain identical electrical performance characteristics and operating temperature specifications. Inventory availability and lead time considerations may also influence part selection.

Frequently Asked Questions (FAQ)

Q: Can TST-117-03-G-D be used as a direct replacement for TSS-117-03-G-D?

A: Yes. Both parts share identical mating pitch (0.100"), position count (34), row configuration (2), contact geometry, gold plating specifications, and operating temperature range (-55°C to 125°C). The series designation difference (TST versus TSS) reflects internal Samtec product line organization and does not affect functional compatibility.

Q: What is the difference between the insulation materials?

A: The TSS-117-03-G-D uses standard Polybutylene Terephthalate (PBT), while the TST-117-03-G-D uses glass-filled PBT. Glass-filled PBT provides improved mechanical strength and dimensional stability. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range.

Q: Are the contact specifications identical?

A: Yes. Both parts feature phosphor bronze contacts with gold plating at 10.0µin (0.25µm) on mating surfaces and 3.00µin (0.076µm) on posts. Contact length, shape (square), and overall dimensions are identical.

Q: Do both parts support the same mounting configuration?

A: Yes. Both are through-hole mounted headers with solder termination, shrouded 4-wall construction, and push-pull fastening. Keying slots are present on both parts.

Q: What is the current rating for these connectors?

A: The TST-117-03-G-D is rated at 3.4A per contact. The TSS-117-03-G-D does not specify a current rating in the provided data.

Q: Are both parts RoHS compliant?

A: Yes. Both the TSS-117-03-G-D and TST-117-03-G-D are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
