Substitute Part Grouping Explanation

Substitution of the TSS-120-05-G-D-RA is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 40
• 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
• Termination: Solder
• 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 (MSL): 1 (Unlimited)

The TST-120-05-G-D-RA meets all critical substitution criteria. Variations in Series designation (TSS vs. TST), Style classification (Board to Board or Cable vs. Board to Cable/Wire), Insulation Material composition (PBT vs. PBT Glass Filled), and Current Rating specification do not preclude functional equivalence for applications where these parameters are not design-limiting factors.

Parameter Comparison

Engineering Selection Recommendations

Both TSS-120-05-G-D-RA and TST-120-05-G-D-RA are Active products manufactured by Samtec Inc. with identical compliance certifications: ROHS3 Compliant, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity. The parts share equivalent electrical and mechanical specifications across all critical mating and mounting parameters.

Selection between these parts should be based on application-specific requirements regarding insulation material composition and current handling capacity. The TST-120-05-G-D-RA specifies glass-filled PBT insulation and a current rating of 3.4A per contact, whereas the TSS-120-05-G-D-RA does not specify these parameters. Both parts maintain identical operating temperature range (-55°C ~ 125°C) and contact geometry.

Frequently Asked Questions (FAQ)

Q: Can TST-120-05-G-D-RA replace TSS-120-05-G-D-RA in existing designs?

A: Yes, provided the application does not require specific insulation material properties or current ratings that differ between the parts. Both connectors share identical pitch (0.100"), position count (40), row configuration (2 rows), mounting type (through-hole right-angle), shrouding (4-wall), and contact specifications (gold-plated phosphor bronze).

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

A: Series designation reflects product line classification within Samtec's Flex Stack connector family. The TSS series is classified as Board to Board or Cable, while the TST series is classified as Board to Cable/Wire. This distinction does not affect electrical or mechanical compatibility for applications where both configurations are acceptable.

Q: Does the glass-filled PBT insulation in TST-120-05-G-D-RA affect compatibility?

A: Glass-filled PBT provides enhanced mechanical and thermal properties compared to standard PBT. Compatibility depends on application requirements. If the design specifies standard PBT insulation material, the glass-filled variant may not be suitable without design review.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both TSS-120-05-G-D-RA and TST-120-05-G-D-RA operate across -55°C to 125°C and maintain UL94 V-0 flammability rating across this range.

Q: What is the significance of the current rating specification in TST-120-05-G-D-RA?

A: The TST-120-05-G-D-RA specifies 3.4A per contact current capacity. The TSS-120-05-G-D-RA does not specify a current rating. If the application requires documented current handling capacity, the TST-120-05-G-D-RA provides explicit specification. Applications with current requirements below 3.4A per contact are compatible with both parts.

Q: Are both parts RoHS compliant?

A: Yes. Both TSS-120-05-G-D-RA and TST-120-05-G-D-RA are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity level, suitable for standard PCB assembly and storage conditions.
