TSS-107-04-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSS-107-04-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 connector operates across -55°C to 125°C and meets ROHS3 compliance requirements. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the Flex Stack connector family.

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-107-04-G-D-RA is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins, 14 positions in 2 rows
Pitch & Spacing: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Orientation: Through-hole, right-angle configuration
Shrouding: 4-wall shrouded design with keying slot
Contact Properties: Gold-plated phosphor bronze contacts
Thermal & Compliance: Operating range -55°C to 125°C, UL94 V-0, ROHS3 compliant

The identified substitutes HTST-107-04-G-D-RA and TST-107-04-G-D-RA maintain these core parameters. Variations in insulation material (PBT vs. LCP vs. glass-filled PBT) and application style (board-to-board vs. board-to-cable/wire) do not affect electrical or mechanical interchangeability within the specified parameter set.

Engineering Selection Recommendations

All three parts—TSS-107-04-G-D-RA, HTST-107-04-G-D-RA, and TST-107-04-G-D-RA—maintain active product status with ROHS3 compliance and REACH unaffected designation. Each part carries UL94 V-0 flammability certification and operates within the -55°C to 125°C temperature range. Selection between these parts should be based on application-specific requirements regarding insulation material composition and connector style (board-to-board vs. board-to-cable/wire), as all electrical and mechanical parameters remain equivalent across the three options.

Frequently Asked Questions (FAQ)

Q: Can TSS-107-04-G-D-RA be directly replaced with HTST-107-04-G-D-RA or TST-107-04-G-D-RA?

A: Yes. All three parts share identical connector type, contact configuration, pitch, row spacing, mounting orientation, shrouding, contact materials, and thermal operating range. The parts are electrically and mechanically interchangeable within the specified parameter set.

Q: What are the differences between the three substitute parts?

A: The primary differences are insulation material and application style. TSS-107-04-G-D-RA uses polybutylene terephthalate (PBT) for board-to-board applications. HTST-107-04-G-D-RA uses liquid crystal polymer (LCP) for board-to-cable/wire applications. TST-107-04-G-D-RA uses glass-filled PBT for board-to-cable/wire applications. These variations do not affect electrical or mechanical compatibility.

Q: Are all parts ROHS3 compliant?

A: Yes. TSS-107-04-G-D-RA, HTST-107-04-G-D-RA, and TST-107-04-G-D-RA are all ROHS3 compliant with REACH unaffected status.

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

A: All three parts operate across -55°C to 125°C.

Q: Do these connectors have keying features?

A: Yes. All three parts include a keying slot as a standard feature.

Q: What is the moisture sensitivity level?

A: All three parts have a moisture sensitivity level of 1 (Unlimited), indicating no moisture sensitivity restrictions.
