Parameter Comparison

Engineering Selection Recommendations

Both TSS-112-03-G-D and TST-112-03-G-D are active production parts manufactured by Samtec Inc. with identical compliance certifications including RoHS3 and UL94 V-0 flammability ratings. The parts share all critical electrical and mechanical parameters including contact geometry, pitch spacing, termination method, and operating temperature range.

The TST-112-03-G-D substitute provides an additional specification of 3.4A per contact current rating, which is not declared for the main part. The TST series uses glass-filled PBT insulation material compared to standard PBT in the TSS series. The style designation differs, with TSS supporting board-to-board or cable configurations while TST is specified for board-to-cable/wire applications.

Selection between these parts should be based on application-specific requirements regarding connector style compatibility and current handling specifications.

Frequently Asked Questions (FAQ)

Q: What determines if TST-112-03-G-D can substitute for TSS-112-03-G-D?

A: Substitution is valid when the following parameters match: connector type, contact type, number of positions, number of rows, mating pitch, row spacing, mounting type, shrouding configuration, termination method, contact geometry, contact finish specifications, contact material, insulation material base composition, operating temperature range, and compliance certifications. Both parts meet these criteria.

Q: Are there differences in mechanical compatibility?

A: The parts are mechanically compatible in terms of PCB footprint, contact spacing, and mounting hole patterns. The primary mechanical difference is the insulation material composition: TST-112-03-G-D uses glass-filled PBT while TSS-112-03-G-D uses standard PBT. This affects insulation material properties but does not impact mating interface compatibility.

Q: What is the significance of the style designation difference?

A: TSS-112-03-G-D is designated for board-to-board or cable applications, while TST-112-03-G-D is designated for board-to-cable/wire applications. This reflects the intended mating connector type but does not affect the header's physical or electrical characteristics.

Q: Does the current rating difference affect substitution?

A: The TST-112-03-G-D specifies 3.4A per contact while the TSS-112-03-G-D does not declare a current rating. If the application requires current handling verification, the TST-112-03-G-D provides explicit specification. For applications where current rating is not a limiting factor, both parts are functionally equivalent.

Q: Are both parts available in the same packaging?

A: Both parts are supplied in bulk packaging. Current inventory shows 698 units of TSS-112-03-G-D and 823 units of TST-112-03-G-D available as new original stock.

Q: What compliance certifications apply to both parts?

A: Both TSS-112-03-G-D and TST-112-03-G-D are RoHS3 compliant and carry UL94 V-0 material flammability ratings. Both have moisture sensitivity level 1 (unlimited). These certifications are identical across both parts.
