Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 24 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding Design: Shrouded 4-wall construction
• Contact Material & Finish: Phosphor bronze with gold plating
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature Range: -55°C ~ 125°C
• Compliance Standards: ROHS3 compliant, UL94 V-0 rated

The TST-112-05-G-D-RA qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary distinction lies in the application style (board-to-cable/wire versus board-to-board) and insulation material composition (glass-filled PBT), which do not affect core connector functionality within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-112-05-G-D-RA and TST-112-05-G-D-RA maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on application requirements:

The TSS-112-05-G-D-RA is specified for board-to-board or cable applications with standard PBT insulation material.

The TST-112-05-G-D-RA is specified for board-to-cable/wire applications with glass-filled PBT insulation and provides a documented current rating of 3.4A per contact. The glass-filled insulation composition offers enhanced mechanical and thermal properties.

Both connectors share identical electrical and mechanical interface parameters, including pitch, position count, contact geometry, and operating temperature range. Selection should be based on the specific application style (board-to-board versus board-to-cable/wire) and whether the enhanced insulation properties of the glass-filled variant are required.

Frequently Asked Questions (FAQ)

Q: Can the TST-112-05-G-D-RA replace the TSS-112-05-G-D-RA in a board-to-board application?

A: The TST-112-05-G-D-RA is specified for board-to-cable/wire applications. While the electrical and mechanical interface parameters are identical, the application style designation should be observed for design compliance.

Q: What is the difference between standard PBT and glass-filled PBT insulation?

A: Glass-filled PBT provides enhanced mechanical strength and thermal stability compared to standard PBT. The TST-112-05-G-D-RA uses glass-filled PBT, while the TSS-112-05-G-D-RA uses standard PBT. Both materials meet UL94 V-0 flammability requirements.

Q: Are the contact dimensions identical between these two parts?

A: Yes. Both parts feature identical contact length specifications (0.250" mating, 0.230" post), insulation height (0.365"), and contact geometry (square shape).

Q: What is the current rating for the TSS-112-05-G-D-RA?

A: The current rating for the TSS-112-05-G-D-RA is not specified in the provided data. The TST-112-05-G-D-RA is rated at 3.4A per contact.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the TSS-112-05-G-D-RA and TST-112-05-G-D-RA operate across -55°C to 125°C.

Q: Are both parts ROHS3 compliant?

A: Yes. Both parts are ROHS3 compliant with UL94 V-0 flammability certification.

Q: What is the pitch specification for these connectors?

A: Both connectors feature a 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing in a 2-row, 24-position configuration.
