TSS-136-03-G-D Equivalent & Substitute Parts

Part Overview

The TSS-136-03-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 72-position, 2-row connector operates within the Flex Stack TSS series and is classified as active product status. The connector features shrouded 4-wall construction with push-pull fastening, suitable for board-to-board or cable interconnections. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where form factor and performance requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-136-03-G-D is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• 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
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• 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 (MSL): 1 (Unlimited)

The TST-136-03-G-D qualifies as a substitute part based on these parameters. Variations in series designation (TST versus TSS), insulation material composition (glass-filled PBT), style classification (board to cable/wire versus board to board or cable), and current rating specification do not preclude substitution when the core electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-136-03-G-D and TST-136-03-G-D maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. The TST-136-03-G-D provides equivalent electrical and mechanical performance with identical contact geometry, pitch spacing, and operating temperature range. The glass-filled PBT insulation material in the TST variant offers enhanced mechanical properties compared to standard PBT. Both connectors are suitable for applications requiring 72-position through-hole headers with 2.54mm pitch and push-pull fastening. Selection between these parts should be based on inventory availability and specific application requirements regarding insulation material composition.

Frequently Asked Questions (FAQ)

Q: Can TST-136-03-G-D replace TSS-136-03-G-D in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications including pitch, contact geometry, operating temperature range, and flammability rating. The primary difference is the series designation and insulation material composition. Substitution is valid when the application does not impose specific material requirements beyond the provided specifications.

Q: What is the significance of glass-filled PBT in the TST-136-03-G-D?

A: Glass-filled PBT provides enhanced mechanical strength and dimensional stability compared to standard PBT. This material modification does not alter the electrical performance or compatibility of the connector within the specified operating parameters.

Q: Are the contact dimensions identical between these parts?

A: Yes. Both connectors feature identical contact length specifications: 0.250" (6.35mm) mating length, 0.565" (14.35mm) post length, and 0.930" (23.62mm) overall contact length. Insulation height and contact shape are also identical.

Q: Do both parts support the same fastening mechanism?

A: Yes. Both connectors utilize push-pull fastening with keying slot features. The mechanical interface and mating force characteristics are equivalent.

Q: What is the current rating difference between these parts?

A: The TST-136-03-G-D specifies a current rating of 3.4A per contact. The TSS-136-03-G-D does not provide a current rating specification in the available data. When current rating is a critical design parameter, the TST-136-03-G-D provides explicit specification for this characteristic.

Q: Are both parts RoHS compliant?

A: Yes. Both connectors are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
