TSS-107-05-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSS-107-05-G-D-RA is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 14-position, 2-row connector operates across -55°C to 125°C and meets UL94 V-0 flammability standards with ROHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent configurations.

Substitute Part Grouping Explanation

Substitution of the TSS-107-05-G-D-RA with the TST-107-05-G-D-RA is based on equivalence in the following critical parameters:

Connector Configuration: Both parts maintain 14 positions across 2 rows with 0.100" (2.54mm) pitch and row spacing
Mounting and Termination: Both feature through-hole, right-angle mounting with solder termination
Contact Specifications: Identical male pin contact type, phosphor bronze material, gold mating finish, and 0.250" (6.35mm) mating contact length
Shrouding and Keying: Both incorporate 4-wall shrouding with keying slot
Electrical and Environmental: Both operate across -55°C to 125°C, meet UL94 V-0 flammability, and comply with ROHS3
Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary difference lies in the connector series designation (TSS versus TST) and the intended mating style (board-to-board or cable versus board-to-cable/wire), along with minor material composition variations in the insulation (glass-filled PBT in the substitute).

Engineering Selection Recommendations

Both the TSS-107-05-G-D-RA and TST-107-05-G-D-RA are active products from Samtec Inc. with identical compliance certifications (ROHS3, UL94 V-0, MSL 1). Selection between these parts should be based on the specific mating interface requirement: the TSS series is designated for board-to-board or cable applications, while the TST series is specified for board-to-cable/wire configurations. The TST-107-05-G-D-RA provides an explicit current rating of 3.4A per contact, whereas the main part does not specify this parameter. The glass-filled PBT insulation material in the TST variant may offer enhanced mechanical properties in specific thermal or mechanical stress environments.

Frequently Asked Questions (FAQ)

Q: Can the TST-107-05-G-D-RA directly replace the TSS-107-05-G-D-RA in all applications?

A: Direct substitution is possible when the mating interface requirement aligns with the TST series specification (board-to-cable/wire). Both parts share identical pitch, row spacing, contact configuration, and environmental ratings. Verify that your application's mating connector is compatible with the TST series designation before substitution.

Q: What is the significance of the series designation difference (TSS versus TST)?

A: The series designation indicates the intended mating style. TSS is specified for board-to-board or cable applications, while TST is specified for board-to-cable/wire applications. This distinction affects connector compatibility and should be verified against your specific mating connector type.

Q: Are there differences in mechanical performance between these parts?

A: The TST-107-05-G-D-RA incorporates glass-filled PBT insulation material, compared to standard PBT in the TSS-107-05-G-D-RA. Both maintain identical operating temperature ranges (-55°C to 125°C) and UL94 V-0 flammability ratings. The glass-filled variant may provide enhanced rigidity and thermal stability in specific applications.

Q: Is the current rating difference significant for substitution?

A: The TST-107-05-G-D-RA specifies 3.4A per contact, while the TSS-107-05-G-D-RA does not provide this specification. If your application requires a defined current rating, the TST variant provides explicit electrical performance data. Verify that your application's current requirements do not exceed 3.4A per contact when using the TST substitute.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TSS-107-05-G-D-RA and TST-107-05-G-D-RA are ROHS3 compliant, UL94 V-0 rated, and classified as MSL 1 (Unlimited). Both are active products with identical moisture sensitivity levels.
