Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-112-05-T-D-RA is determined by strict alignment of the following critical parameters:

Electrical Parameters: Connector type (Header), contact type (Male Pin), number of positions (24), number of rows (2), pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), contact material (Phosphor Bronze), contact finish (Tin), and operating temperature range (-55°C ~ 105°C).

Mechanical Parameters: Mounting type (Through Hole, Right Angle), shrouding configuration (Shrouded - 4 Wall), termination method (Solder), fastening type (Push-Pull), contact length specifications (Mating: 0.250" / 6.35mm; Post: 0.230" / 5.84mm), insulation height (0.365" / 9.27mm), and contact shape (Square).

Compliance Parameters: Material flammability rating (UL94 V-0), RoHS status (ROHS3 Compliant), and moisture sensitivity level (MSL 1).

The TST-112-05-T-D-RA qualifies as a substitute part because it maintains equivalence across all critical electrical, mechanical, and compliance parameters. The primary distinction is the application style designation (Board to Cable/Wire versus Board to Board or Cable) and insulation material composition (Glass Filled PBT addition), which do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-112-05-T-D-RA and TST-112-05-T-D-RA maintain active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific requirements and inventory availability.

The TSS-112-05-T-D-RA is designated for board-to-board or cable applications with standard PBT insulation material. The TST-112-05-T-D-RA is designated for board-to-cable/wire applications with glass-filled PBT insulation, which provides enhanced mechanical and thermal properties. Both parts share identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, operating temperature range, and termination method.

Current inventory levels show 1031 units of TSS-112-05-T-D-RA and 778 units of TST-112-05-T-D-RA available. Selection should account for application style requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can TST-112-05-T-D-RA be used as a direct replacement for TSS-112-05-T-D-RA?

A: Yes. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, contact materials, and operating temperature range. The primary difference is the application style designation and insulation material composition (glass-filled PBT in the TST variant), which do not affect functional interchangeability.

Q: What is the difference between the TSS and TST series designations?

A: The TSS series is designated for board-to-board or cable applications, while the TST series is designated for board-to-cable/wire applications. The TST variant includes glass-filled PBT insulation material, which provides enhanced mechanical and thermal properties suitable for wire termination applications.

Q: Are both parts RoHS compliant?

A: Yes. Both TSS-112-05-T-D-RA and TST-112-05-T-D-RA are ROHS3 compliant with UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 105°C, providing equivalent thermal performance for industrial and commercial applications.

Q: Do these connectors support the same contact configuration?

A: Yes. Both parts feature 24 positions arranged in 2 rows with 0.100" (2.54mm) pitch and row spacing, male pin contacts, square contact shape, phosphor bronze contact material with tin finish, and identical contact length specifications.

Q: What mounting method do these connectors use?

A: Both parts use through-hole, right-angle mounting with solder termination and push-pull fastening type, suitable for PCB assembly processes.
