TSS-136-04-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSS-136-04-G-D-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 72-position connector operates across -55°C to 125°C and features shrouded 4-wall construction with gold-plated phosphor bronze contacts. The part is Active status and ROHS3 compliant. Identifying equivalent substitute parts is necessary when the primary part is unavailable or when design requirements permit alternative connector series that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the TSS-136-04-G-D-RA is permissible with the TST-136-04-G-D-RA based on the following criteria:

Critical matching parameters:

• Number of Positions: 72
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Contact Type: Male Pin
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable variation:

• Style: TSS-136-04-G-D-RA is Board to Board or Cable; TST-136-04-G-D-RA is Board to Cable/Wire. Both accommodate the same mating interface.
• Insulation Material: TSS uses PBT; TST uses PBT Glass Filled. Both meet UL94 V-0 requirements.
• Current Rating: TST-136-04-G-D-RA specifies 3.4A per Contact; TSS-136-04-G-D-RA does not specify current rating. This does not preclude substitution when current requirements are within TST specifications.

Parameter Comparison

Engineering Selection Recommendations

Both TSS-136-04-G-D-RA and TST-136-04-G-D-RA are Active status products manufactured by Samtec Inc. and maintain identical electrical and mechanical interface specifications. Both connectors are ROHS3 compliant and rated UL94 V-0 for flammability. The TST-136-04-G-D-RA provides explicit current rating specification of 3.4A per contact, which may be advantageous for applications requiring documented electrical performance parameters. The glass-filled PBT insulation material in the TST variant offers enhanced mechanical properties compared to standard PBT. Selection between these parts should be based on application-specific requirements for current capacity and insulation material performance, with both parts suitable for equivalent board-to-board and cable interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can TST-136-04-G-D-RA replace TSS-136-04-G-D-RA in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), position count (72), shrouding configuration (4-wall), contact material (phosphor bronze with gold plating), and operating temperature range (-55°C to 125°C). The primary difference is insulation material composition and documented current rating.

Q: What is the difference between the Style designations (Board to Board or Cable vs. Board to Cable/Wire)?

A: Both style designations accommodate the same 0.100" (2.54mm) pitch mating interface. The TSS series supports board-to-board or cable applications, while the TST series is specified for board-to-cable/wire applications. Both are compatible with standard 0.100" pitch receptacles.

Q: Does the glass-filled PBT insulation in TST-136-04-G-D-RA affect compatibility?

A: No. Glass-filled PBT maintains the same electrical and mechanical interface specifications as standard PBT. The glass filler enhances mechanical strength and thermal stability without altering connector geometry or mating characteristics.

Q: Is the current rating specification of 3.4A per contact in TST-136-04-G-D-RA a limiting factor?

A: The TST-136-04-G-D-RA specifies 3.4A per contact. Applications requiring higher current per contact should reference the TSS-136-04-G-D-RA datasheet for its current rating specification. Both parts are suitable for standard signal and moderate power distribution applications.

Q: Are both parts available in the same packaging?

A: Yes. Both TSS-136-04-G-D-RA and TST-136-04-G-D-RA are supplied in Tube packaging.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, rated UL94 V-0 for flammability, and carry Moisture Sensitivity Level 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.
