TST-104-01-L-D Equivalent & Substitute Parts

Part Overview

The TST-104-01-L-D is an 8-position rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting with 0.100" (2.54mm) pitch. This connector operates across the industrial temperature range of -55°C to 125°C and is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the connector footprint and electrical characteristics remain constant.

The identified substitute parts HTST-104-01-L-D and TSS-104-01-L-D meet all critical electrical and mechanical parameters. Variations in insulation material (PBT Glass Filled vs. LCP vs. PBT) and insulation color do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TST-104-01-L-D, HTST-104-01-L-D, and TSS-104-01-L-D—maintain Active product status and ROHS3 compliance. The primary distinction lies in insulation material composition: the TST-104-01-L-D and TSS-104-01-L-D utilize PBT-based insulation, while the HTST-104-01-L-D employs Liquid Crystal Polymer (LCP). All parts satisfy UL94 V-0 flammability requirements and operate within the identical temperature range. Selection between these parts should be based on application-specific requirements regarding insulation material properties and availability. The TSS-104-01-L-D supports both board-to-board and cable applications, whereas the TST-104-01-L-D is specified for board-to-cable/wire configurations.

Frequently Asked Questions (FAQ)

Q: Can TST-104-01-L-D be directly replaced with HTST-104-01-L-D?

A: Yes. Both connectors share identical electrical and mechanical specifications including pitch, contact configuration, mounting type, and operating temperature range. The insulation material difference (PBT Glass Filled vs. LCP) does not affect functional compatibility in standard applications.

Q: What is the primary difference between TST-104-01-L-D and TSS-104-01-L-D?

A: The TST-104-01-L-D is designated for board-to-cable/wire applications, while the TSS-104-01-L-D supports both board-to-board and cable configurations. Both maintain identical contact geometry, pitch, and electrical ratings.

Q: Are all three parts RoHS compliant?

A: Yes. TST-104-01-L-D, HTST-104-01-L-D, and TSS-104-01-L-D are all ROHS3 compliant.

Q: What is the current rating for these connectors?

A: The TST-104-01-L-D and HTST-104-01-L-D are rated at 3.4A per contact. The TSS-104-01-L-D current rating is not specified in the provided data.

Q: Do these connectors support the same operating temperature range?

A: Yes. All three parts operate across -55°C to 125°C.

Q: What is the significance of the keying slot feature?

A: The keying slot prevents incorrect mating orientation, ensuring proper connector alignment during assembly.

Q: Are these connectors suitable for high-reliability applications?

A: All three parts meet UL94 V-0 flammability standards and maintain Active product status with established supply chains, supporting deployment in industrial and commercial applications.
