Substitute Part Grouping Explanation

Substitution eligibility for the TSS-113-05-G-D-RA is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 26 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Orientation: Through-hole, right-angle mounting
Shrouding Design: Shrouded with 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 flammability rating

The TST-113-05-G-D-RA qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in application style (Board to Cable/Wire versus Board to Board or Cable) and insulation material composition (glass-filled PBT) do not affect functional interchangeability within the specified parameter constraints.

Engineering Selection Recommendations

Both the TSS-113-05-G-D-RA and TST-113-05-G-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:

The TSS-113-05-G-D-RA is specified for board-to-board or cable applications with standard PBT insulation material.

The TST-113-05-G-D-RA is specified for board-to-cable/wire applications with glass-filled PBT insulation, which provides enhanced mechanical strength and thermal stability. The glass-filled variant also carries a current rating specification of 3.4A per contact, whereas the main part does not specify current rating.

Both parts share identical electrical and mechanical interface parameters, ensuring mechanical and electrical compatibility within the defined operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TST-113-05-G-D-RA replace TSS-113-05-G-D-RA in existing designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (26), row configuration (2 rows), mounting type (through-hole right-angle), shrouding design (4-wall), contact material (phosphor bronze with gold finish), and operating temperature range (-55°C to 125°C). The difference in insulation material composition (glass-filled PBT versus standard PBT) does not affect functional interchangeability.

Q: What is the significance of glass-filled PBT insulation in the TST-113-05-G-D-RA?

A: Glass-filled PBT provides improved mechanical rigidity and thermal performance compared to standard PBT. This material enhancement is reflected in the TST-113-05-G-D-RA's specified current rating of 3.4A per contact.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both TSS-113-05-G-D-RA and TST-113-05-G-D-RA operate across -55°C to 125°C and maintain UL94 V-0 flammability compliance across this range.

Q: What is the primary application difference between these two parts?

A: The TSS-113-05-G-D-RA is designated for board-to-board or cable applications, while the TST-113-05-G-D-RA is designated for board-to-cable/wire applications. Both maintain identical mating interface specifications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both TSS-113-05-G-D-RA and TST-113-05-G-D-RA are ROHS3 compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited).
