TSW-136-14-T-S Equivalent & Substitute Parts

Part Overview

The TSW-136-14-T-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This unshrouded, 36-position male pin header operates at 0.100" (2.54mm) pitch and is rated for -55°C to 105°C operating temperatures. The connector features solder termination with push-pull fastening and is constructed from phosphor bronze contacts with PBT insulation. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain compatibility across manufacturing batches and procurement cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-136-14-T-S is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 36 positions, single row
• Pitch Specification: 0.100" (2.54mm) mating pitch is mandatory for mechanical and electrical compatibility
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Electrical & Mechanical Tolerances: Contact length, insulation height, and overall dimensions must accommodate standard PCB footprints
• Environmental & Compliance Standards: UL94 V-0 flammability rating, RoHS compliance, and MSL 1 rating ensure regulatory and reliability alignment
• Operating Temperature: Minimum -40°C to 105°C range acceptable; -55°C to 105°C preferred for full compatibility

The 3M 929700-01-36-RK meets these substitution criteria with minor variations in contact material (copper alloy vs. phosphor bronze) and insulation material (PCT vs. PBT), both of which are functionally equivalent for this application class.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-136-14-T-S and 929700-01-36-RK maintain Active product status and meet current regulatory requirements. Selection between these parts is based on the following provided specifications:

TSW-136-14-T-S (Samtec Inc.) is the primary specification. This part offers the full operating temperature range of -55°C to 105°C and is RoHS3 compliant. Phosphor bronze contact material provides established performance characteristics in standard through-hole applications.

929700-01-36-RK (3M) is a qualified substitute with equivalent mechanical and electrical performance. The operating temperature range is -40°C to 105°C, which is suitable for applications not requiring the extended -55°C lower limit. The breakaway header feature provides additional design flexibility. Copper alloy contacts and PCT insulation material are functionally equivalent to the primary part for this connector class. Current rating of 2.5A is specified for the 3M part.

Both parts carry identical compliance certifications (UL94 V-0, RoHS, REACH Unaffected, EAR99, MSL 1). Contact dimension variances are within acceptable tolerances for standard PCB footprints. Selection should be based on supply availability, procurement lead time, and specific application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the 929700-01-36-RK be used as a direct replacement for the TSW-136-14-T-S in all applications?

A: The 929700-01-36-RK is compatible for applications operating within -40°C to 105°C. If your application requires operation below -40°C, the TSW-136-14-T-S with its -55°C lower limit is required. All other electrical and mechanical parameters are compatible.

Q: What is the significance of the "Breakaway" feature on the 3M part?

A: The breakaway feature allows individual pins to be separated from the header strip if needed for custom configurations. This does not affect compatibility when used as a complete 36-position header in standard applications.

Q: Are the contact material differences (phosphor bronze vs. copper alloy) significant?

A: Both materials provide equivalent electrical conductivity and mechanical durability for 0.100" pitch through-hole header applications. The choice between them does not affect functional compatibility or performance in standard PCB mounting scenarios.

Q: Do the insulation material differences (PBT vs. PCT) affect compatibility?

A: Both PBT and PCT are high-performance thermoplastic materials with equivalent flammability ratings (UL94 V-0) and thermal stability for this application class. The materials are functionally interchangeable for standard through-hole connector use.

Q: What does the 0.05mm variance in mating contact length mean for PCB design?

A: The contact length variance (8.13mm vs. 8.08mm) is within standard manufacturing tolerances and does not require PCB footprint modification. Both parts are compatible with standard 0.100" pitch header footprints.

Q: Is the 2.5A current rating specified for the 3M part a limiting factor?

A: The 2.5A rating for the 3M part is provided in the specification. Applications requiring higher current capacity per contact should reference the primary TSW-136-14-T-S specification or consult manufacturer datasheets for detailed current handling characteristics.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet identical compliance standards (RoHS, REACH, UL94 V-0) and carry MSL 1 rating. Selection for high-reliability applications should be based on specific environmental requirements, particularly the operating temperature range needed for your design.
