TSS-110-03-T-D Equivalent & Substitute Parts

Part Overview

The TSS-110-03-T-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This shrouded 20-position connector operates within the Flex Stack TSS series and is classified as Active product status. The connector accommodates board-to-board or cable interconnections with a 0.100" (2.54mm) pitch configuration. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-110-03-T-D is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 20
• 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
• Operating Temperature Range: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The TST-110-03-T-D qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in series designation (TST versus TSS) and application style (Board to Cable/Wire versus Board to Board or Cable) do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-110-03-T-D and TST-110-03-T-D maintain Active product status with ROHS3 compliance and UL94 V-0 flammability certification. The TST-110-03-T-D substitute incorporates glass-filled polybutylene terephthalate insulation material, which provides enhanced mechanical and thermal properties compared to standard PBT. Both connectors satisfy identical electrical and mechanical specifications for 20-position, 2.54mm pitch through-hole header applications. Selection between these parts depends on inventory availability and application-specific requirements for insulation material composition.

Frequently Asked Questions (FAQ)

Q: Can TST-110-03-T-D replace TSS-110-03-T-D in existing designs?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (20), row configuration (2 rows), mounting type (through-hole), and operating temperature range (-55°C ~ 105°C). The primary difference is the insulation material composition; TST-110-03-T-D uses glass-filled PBT versus standard PBT in the TSS-110-03-T-D.

Q: What is the significance of glass-filled insulation material in the TST-110-03-T-D?

A: Glass-filled polybutylene terephthalate provides improved mechanical strength, dimensional stability, and thermal performance compared to unfilled PBT. This material enhancement does not alter electrical or mechanical compatibility for connector mating and termination.

Q: Are both connectors RoHS compliant?

A: Yes. Both TSS-110-03-T-D and TST-110-03-T-D are ROHS3 compliant with UL94 V-0 flammability certification and MSL rating of 1 (Unlimited).

Q: What are the key parameters that determine substitution eligibility?

A: Critical parameters include connector type (Header), contact type (Male Pin), position count (20), row count (2), mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), mounting type (Through Hole), termination method (Solder), shrouding configuration (Shrouded - 4 Wall), and operating temperature range (-55°C ~ 105°C).

Q: Do these connectors support keying?

A: Yes. Both TSS-110-03-T-D and TST-110-03-T-D include keying slot features to ensure correct mating orientation.
