TST-117-01-S-D Equivalent & Substitute Parts

Part Overview

The TST-117-01-S-D is an active rectangular connector header manufactured by Samtec Inc. in the Flex Stack series. This through-hole mounted connector features 34 positions arranged in 2 rows with 0.100" (2.54mm) pitch and is designed for board-to-cable/wire applications. The part is ROHS3 compliant and carries UL94 V-0 flammability rating. Equivalent parts are identified when functional and mechanical parameters align within acceptable tolerances for the intended application, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 5103309-7 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following critical parameters:

• Identical connector type (Header), contact type (Male Pin), and position count (34 positions in 2 rows)
• Matching mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Identical mounting method (Through Hole) and shrouding configuration (Shrouded - 4 Wall)
• Matching fastening type (Push-Pull) and termination method (Solder)
• Equivalent compliance status (ROHS3 Compliant, UL94 V-0)
• Identical contact finish on mating surface (Gold) and post surface (Tin)
• Same moisture sensitivity level (MSL 1 - Unlimited)

Substitution is valid where these core mechanical and electrical parameters are the controlling factors for connector interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both TST-117-01-S-D and 5103309-7 are active products with equivalent compliance certifications (ROHS3 Compliant, UL94 V-0). Selection between these parts should account for the following documented differences:

The TST-117-01-S-D supports a higher current rating of 3.4A per contact compared to 5103309-7 at 1A per contact. Applications requiring higher current capacity per contact should specify the Samtec part.

The TST-117-01-S-D operates across a wider temperature range (-55°C to 125°C) versus the TE Connectivity part (-65°C to 105°C). Applications with extreme low-temperature requirements below -55°C or sustained high-temperature operation above 105°C require the Samtec specification.

Contact length dimensions differ between the two parts. The TST-117-01-S-D mating contact length is 0.250" (6.35mm) with post length of 0.115" (2.92mm), while 5103309-7 provides 0.240" (6.10mm) mating and 0.120" (3.05mm) post lengths. Insulation height also varies (0.350" versus 0.388"). PCB layout and mating connector geometry must accommodate these dimensional variations.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, supporting equivalent regulatory and trade compliance.

Frequently Asked Questions (FAQ)

Q: Can 5103309-7 be used as a direct replacement for TST-117-01-S-D in all applications?

A: Substitution is valid where the application does not depend on the higher current rating (3.4A vs 1A per contact) or the extended temperature range (-55°C to 125°C vs -65°C to 105°C) of the Samtec part. Contact length and insulation height differences must be evaluated against PCB layout and mating connector specifications.

Q: What are the critical parameters that define interchangeability between these parts?

A: Interchangeability is determined by matching connector type (Header), contact type (Male Pin), position count (34 in 2 rows), mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), mounting method (Through Hole), shrouding (Shrouded - 4 Wall), fastening type (Push-Pull), and termination method (Solder).

Q: How do the contact materials differ between these parts?

A: TST-117-01-S-D uses Phosphor Bronze contacts while 5103309-7 uses Brass contacts. Both are plated with Gold on the mating surface and Tin on the post surface. Material selection may influence contact resistance and durability characteristics in specific applications.

Q: Are there packaging differences between these parts?

A: TST-117-01-S-D is supplied in Bulk packaging while 5103309-7 is supplied in Tube packaging. Procurement and handling procedures may differ accordingly.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 Compliant and carry UL94 V-0 flammability rating. Both are classified as EAR99 for export control and share the same HTSUS code (8536.69.4040). Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts.
