Key Parameters

Substitute Part Grouping Explanation

The TSS-112-01-F-D qualifies as a direct substitute based on the following critical parameters:

Matching Electrical & Mechanical Specifications:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (24 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method and termination (Through Hole, Solder)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Contact geometry and finish (Square shape, Gold mating surface, Tin post finish)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3 Compliant, UL94 V-0)

Acceptable Variations:

• Insulation material differs (LCP vs. PBT) but both materials meet flammability and environmental requirements
• Insulation color variation (Natural vs. Black) does not affect electrical or mechanical function
• Series designation differs (HTST vs. TSS) reflecting different product lines within the same manufacturer

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-112-01-F-D and TSS-112-01-F-D are active production parts manufactured by Samtec Inc. and meet identical compliance requirements including RoHS3 and UL94 V-0 flammability standards. Selection between these parts should be based on:

HTST-112-01-F-D: Use when LCP insulation material is specified or preferred for its superior dimensional stability and chemical resistance properties.

TSS-112-01-F-D: Use when PBT insulation material is acceptable or preferred, or when supply chain availability favors this variant. This part has higher current inventory (1155 units vs. 758 units).

Both parts are electrically and mechanically interchangeable for applications requiring 24-position, 2.54mm pitch through-hole headers with push-pull fastening and 4-wall shrouding.

Frequently Asked Questions (FAQ)

Q: Can TSS-112-01-F-D be used as a direct replacement for HTST-112-01-F-D?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, position count, pitch, mounting method, and operating temperature range. The primary difference is insulation material (PBT vs. LCP), which does not affect functional compatibility in standard applications.

Q: What is the difference between LCP and PBT insulation materials?

A: LCP (Liquid Crystal Polymer) offers superior dimensional stability and chemical resistance. PBT (Polybutylene Terephthalate) is a standard engineering plastic with good mechanical properties. Both materials meet UL94 V-0 flammability requirements. Material selection depends on specific application environmental conditions.

Q: Are the contact specifications identical between these parts?

A: Yes. Both parts use phosphor bronze contacts with gold mating finish (3.00µin thickness) and tin post finish. Contact length, shape, and overall geometry are identical.

Q: Do these parts have the same current rating?

A: The HTST-112-01-F-D specifies 3.4A per contact. The TSS-112-01-F-D does not provide a current rating specification in available documentation. For applications requiring confirmed current ratings, the HTST-112-01-F-D should be referenced.

Q: What does the keying slot feature provide?

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

Q: Are both parts RoHS3 compliant?

A: Yes. Both HTST-112-01-F-D and TSS-112-01-F-D are RoHS3 compliant and meet environmental regulatory requirements.
