TSS-132-05-S-D-RA Equivalent & Substitute Parts

Part Overview

The TSS-132-05-S-D-RA is a rectangular connector header manufactured by Samtec Inc., classified within the Flex Stack TSS series. This through-hole, right-angle connector accommodates 64 positions at 0.100" (2.54mm) pitch and is designed for board-to-board or cable applications. The part is currently active in production with 969 units in stock. Alternative part numbers may be required due to application-specific requirements, inventory constraints, or design modifications that necessitate compatible connector options meeting identical or equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-132-05-S-D-RA is determined by strict equivalence across the following critical parameters:

Number of Positions and Rows: Both the main part and substitute must provide 64 positions arranged in 2 rows to maintain PCB footprint compatibility.

Pitch Specifications: Mating pitch and row spacing must both be 0.100" (2.54mm) to ensure mechanical and electrical interchangeability.

Connector Type and Contact Configuration: Header type with male pin contacts is required for compatibility with corresponding receptacle connectors.

Mounting and Termination: Through-hole, right-angle mounting with solder termination must be preserved.

Shrouding and Keying: Shrouded 4-wall design with keying slot ensures proper alignment and prevents mating errors.

Contact Materials and Finishes: Phosphor bronze contacts with gold mating finish and tin post finish maintain electrical performance and reliability.

Insulation Material: PBT insulation with UL94 V-0 flammability rating is required for safety and environmental compliance.

Operating Temperature Range: -55°C ~ 125°C operating range must be maintained.

Compliance Standards: RoHS3 compliance and MSL 1 rating are mandatory for regulatory and manufacturing requirements.

Parameter Comparison

Engineering Selection Recommendations

Both TSS-132-05-S-D-RA and TST-132-05-S-D-RA are active products from Samtec Inc. with identical mechanical dimensions, electrical contact specifications, and compliance certifications. The primary distinction lies in the insulation material composition and application context. The TSS series is specified for board-to-board or cable applications, while the TST series is designated for board-to-cable/wire applications. The TST-132-05-S-D-RA includes a documented current rating of 3.4A per contact, whereas the TSS-132-05-S-D-RA does not specify this parameter. The TST variant uses glass-filled PBT insulation, which provides enhanced mechanical strength compared to standard PBT. Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Selection between these parts should be based on the specific application context: board-to-board interconnection favors TSS-132-05-S-D-RA, while board-to-cable/wire interconnection favors TST-132-05-S-D-RA.

Frequently Asked Questions (FAQ)

Q: Are TSS-132-05-S-D-RA and TST-132-05-S-D-RA mechanically interchangeable?

A: Yes. Both parts share identical pitch (0.100"), position count (64), row configuration (2 rows), mounting type (through-hole right-angle), and physical dimensions. PCB footprints are identical.

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

A: The TSS series is specified for board-to-board or cable applications, while the TST series is designated for board-to-cable/wire applications. This distinction reflects the intended mating interface design.

Q: Does the glass-filled PBT insulation in TST-132-05-S-D-RA affect compatibility?

A: No. Glass-filled PBT maintains the same electrical and mechanical interface characteristics as standard PBT. The glass-fill enhancement provides increased mechanical strength without affecting connector compatibility or performance.

Q: Is the current rating difference significant for substitution?

A: The TST-132-05-S-D-RA specifies 3.4A per contact, while the TSS-132-05-S-D-RA does not provide a current rating specification. If current capacity is a design requirement, the TST variant with documented 3.4A rating provides explicit specification. Both parts are suitable for applications within their respective current handling capabilities.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TSS-132-05-S-D-RA and TST-132-05-S-D-RA are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level, meeting current regulatory requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Mechanical and electrical interchangeability is confirmed across all critical parameters. Design validation should confirm that the application context (board-to-board versus board-to-cable/wire) aligns with the selected part series.
