TST-116-01-G-D Equivalent & Substitute Parts

Part Overview

The TST-116-01-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 32-position, 2-row connector operates within the Flex Stack TST series and features shrouded 4-wall construction with push-pull fastening. The part maintains active product status and is ROHS3 compliant with unlimited moisture sensitivity rating. 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 TST-116-01-G-D is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (32 positions)
• Row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Contact finish at mating surface (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)

The HTSS-116-01-G-D meets all substitution criteria within these parameters. Differences in insulation material (PBT Glass Filled versus Liquid Crystal Polymer) and connector series designation (TST versus HTSS) do not affect functional compatibility when these core electrical and mechanical specifications are maintained.

Parameter Comparison

Engineering Selection Recommendations

Both TST-116-01-G-D and HTSS-116-01-G-D maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on availability and insulation material requirements. The TST-116-01-G-D uses PBT glass-filled insulation, while the HTSS-116-01-G-D uses Liquid Crystal Polymer insulation. Both materials satisfy the specified operating temperature range and environmental requirements. Component selection should be determined by inventory availability and any application-specific material performance criteria.

Frequently Asked Questions (FAQ)

Q: Can HTSS-116-01-G-D replace TST-116-01-G-D in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications including pitch, position count, row configuration, contact geometry, operating temperature range, and fastening mechanism. The primary difference is insulation material composition, which does not affect functional compatibility when both materials meet the application's environmental and thermal requirements.

Q: What is the significance of the different insulation materials?

A: TST-116-01-G-D uses PBT glass-filled insulation, while HTSS-116-01-G-D uses Liquid Crystal Polymer insulation. Both materials are UL94 V-0 rated and operate across the identical temperature range. Material selection may be driven by specific mechanical, thermal, or chemical resistance requirements in the application environment.

Q: Are the contact specifications identical between these parts?

A: Yes. Both connectors feature phosphor bronze contacts with gold plating at mating surfaces (10.0µin thickness) and gold plating at posts (3.00µin thickness). Contact length, shape, and overall geometry are identical.

Q: Do both parts support the same mounting and fastening methods?

A: Yes. Both are through-hole mounted with push-pull fastening and shrouded 4-wall construction with keying slots.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification.
