Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-120-01-G-D-01 is determined by 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)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Operating temperature range (-55°C ~ 125°C)
• Contact material (Phosphor Bronze)
• Contact finish - mating (Gold)
• Insulation material (Polybutylene Terephthalate)
• RoHS compliance (ROHS3 Compliant)

The identified substitute parts TST-120-01-G-D-01 and TST-120-01-G-D-20 meet all critical electrical and mechanical parameters. Variations in insulation material composition (glass-filled PBT) and current rating specifications do not affect functional interchangeability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. The TSS-120-01-G-D-01 and substitute parts TST-120-01-G-D-01 and TST-120-01-G-D-20 are electrically and mechanically equivalent within the specified parameter set. Selection between these parts is based on inventory availability and application-specific requirements. The TST series substitutes feature glass-filled PBT insulation material, which provides enhanced mechanical properties compared to standard PBT. Current rating specifications are provided for the TST series parts (3.4A per contact) but not specified for the TSS-120-01-G-D-01 main part.

Frequently Asked Questions (FAQ)

Q: Are TST-120-01-G-D-01 and TST-120-01-G-D-20 interchangeable with TSS-120-01-G-D-01?

A: Yes. Both TST series parts meet all critical electrical and mechanical parameters including connector type, contact configuration, pitch, row spacing, mounting type, shrouding, termination method, fastening type, operating temperature range, contact material, contact finish, and compliance certifications.

Q: What is the difference between TST-120-01-G-D-01 and TST-120-01-G-D-20?

A: Both parts are functionally equivalent. The primary difference is the suffix designation (-01 versus -20), which may indicate different manufacturing batches or internal Samtec product variants. All electrical and mechanical parameters are identical.

Q: Does the glass-filled PBT insulation in the TST series affect compatibility?

A: No. Glass-filled PBT is a material enhancement that does not affect electrical or mechanical interchangeability. It provides improved mechanical properties while maintaining the same form factor and electrical characteristics.

Q: Can these parts be used in board-to-board applications?

A: The TSS-120-01-G-D-01 is specified for board-to-board or cable applications. The TST series substitutes are specified for board-to-cable/wire applications. Both configurations support the same connector interface and mating characteristics.

Q: What is the current rating for the TSS-120-01-G-D-01?

A: The current rating is not specified in the provided parameters for the TSS-120-01-G-D-01. The TST series substitutes are rated at 3.4A per contact.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with UL94 V-0 flammability certification and MSL 1 (Unlimited) moisture sensitivity level.
