TST-108-01-H-D Equivalent & Substitute Parts

Part Overview

The TST-108-01-H-D is a rectangular connector header manufactured by Samtec Inc., part of the Flex Stack TST series. This through-hole mounted connector features 16 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The component is actively produced and stocked, with 806 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in board-to-cable/wire applications while maintaining connector integrity and performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TST-108-01-H-D is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 16
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Contact Shape: Square
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Operating Temperature Range: -55°C ~ 125°C
• Current Rating: 3.4A per Contact
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The TST-108-01-L-D meets all these criteria and qualifies as a direct substitute. Variations in contact finish specifications (mating and post finishes) do not affect functional compatibility when both parts maintain the same electrical performance characteristics and mechanical interface dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the TST-108-01-H-D and TST-108-01-L-D are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts is based on availability and contact finish specifications. The TST-108-01-H-D features gold plating on both mating and post contacts, while the TST-108-01-L-D uses gold on mating contacts and tin on post contacts. Both configurations support the same electrical performance and mechanical interface requirements. The TST-108-01-L-D offers higher inventory availability at 1731 units compared to 806 units for the main part number.

Frequently Asked Questions (FAQ)

Q: Can TST-108-01-L-D be used as a direct replacement for TST-108-01-H-D?

A: Yes. Both parts share identical connector type, contact configuration, pitch spacing, mounting method, and electrical ratings. The parts are mechanically and electrically interchangeable in board-to-cable/wire applications.

Q: What is the difference between these two part numbers?

A: The primary differences are contact finish specifications. TST-108-01-H-D uses gold plating on both mating and post contacts (30.0µin mating, unspecified post thickness). TST-108-01-L-D uses gold plating on mating contacts (10.0µin) and tin plating on post contacts. Both finishes maintain equivalent electrical performance and corrosion resistance for standard applications.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts maintain identical mechanical dimensions, pitch spacing, row configuration, and electrical characteristics. The connector interface and mating surface specifications are equivalent.

Q: Which part should be selected based on availability?

A: TST-108-01-L-D has higher inventory availability (1731 units) compared to TST-108-01-H-D (806 units). Selection may be driven by supply chain requirements and lead time considerations.

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

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, and maintain identical operating temperature ranges (-55°C ~ 125°C) and current ratings (3.4A per contact).
