Substitute Part Grouping Explanation

The TST-103-04-G-D-RA qualifies as a substitute for the TSS-103-04-G-D-RA based on the following alignment of critical parameters:

Matching Parameters:

Connector Type: Header
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 6
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole, Right Angle
Shrouding: Shrouded - 4 Wall
Contact Finish - Mating: Gold
Contact Material: Phosphor Bronze
Insulation Material: Polybutylene Terephthalate (PBT)
Operating Temperature: -55°C ~ 125°C
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Differences:

Style: TSS-103-04-G-D-RA is Board to Board or Cable; TST-103-04-G-D-RA is Board to Cable/Wire
Insulation Material Detail: TST-103-04-G-D-RA includes Glass Filled specification
Current Rating: TST-103-04-G-D-RA specifies 3.4A per Contact; TSS-103-04-G-D-RA does not specify
Series: TSS (Flex Stack) vs. TST (Flex Stack)

These differences do not prevent substitution when the application requirements align with the TST-103-04-G-D-RA specifications.

Engineering Selection Recommendations

Both the TSS-103-04-G-D-RA and TST-103-04-G-D-RA are Active products from Samtec Inc. and maintain ROHS3 compliance with identical operating temperature ranges and flammability ratings. The TST-103-04-G-D-RA offers higher inventory availability (2115 Pcs vs. 791 Pcs) and includes a specified current rating of 3.4A per contact. The glass-filled PBT insulation material in the TST-103-04-G-D-RA provides enhanced mechanical properties. Selection between these parts should be based on application-specific requirements regarding connector style (board-to-board/cable vs. board-to-cable/wire) and current handling specifications.

Frequently Asked Questions (FAQ)

Q: Can TST-103-04-G-D-RA replace TSS-103-04-G-D-RA in all applications?

A: Substitution is valid when the application requirements align with the TST-103-04-G-D-RA specifications. The primary difference is connector style: TSS-103-04-G-D-RA supports board-to-board or cable connections, while TST-103-04-G-D-RA is designed for board-to-cable/wire connections. Confirm your application matches the intended style before substitution.

Q: What is the significance of the glass-filled PBT insulation in TST-103-04-G-D-RA?

A: Glass-filled polybutylene terephthalate provides improved mechanical strength and dimensional stability compared to standard PBT. This material enhancement does not affect electrical compatibility but may offer superior performance in applications requiring higher mechanical stress resistance.

Q: Are the contact specifications identical between these parts?

A: Contact specifications are identical: both use phosphor bronze male pins with gold plating at 0.100" (2.54mm) pitch, 6 positions in a 2-row configuration with 4-wall shrouding. The TST-103-04-G-D-RA explicitly specifies 3.4A per contact current rating.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TSS-103-04-G-D-RA and TST-103-04-G-D-RA are ROHS3 compliant, UL94 V-0 rated, and carry Moisture Sensitivity Level 1 (Unlimited). Both operate across -55°C to 125°C.

Q: What packaging format is used for these connectors?

A: Both parts are supplied in Tube packaging, suitable for automated assembly and manual handling applications.
