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

Part Overview

The HTSS-104-01-L-D is an 8-position rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting with vertical orientation. This shrouded 4-wall header operates across the industrial temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part is actively produced and ROHS3 compliant, making it suitable for applications requiring board-to-board or cable interconnection. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling component interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSS-104-01-L-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 8 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding: 4-wall shrouded design
• Contact Materials & Finish: Phosphor bronze with gold-plated mating surface and tin-plated posts
• Environmental Compliance: Operating temperature range -55°C to 125°C, UL94 V-0 flammability rating, ROHS3 compliance

The identified substitutes HTST-104-01-L-D and TSS-104-01-L-D meet these core electrical and mechanical requirements. Variations in insulation material (LCP versus PBT) and series designation do not affect functional interchangeability when mating pitch, contact configuration, and environmental ratings remain constant.

Parameter Comparison

Engineering Selection Recommendations

All three parts—HTSS-104-01-L-D, HTST-104-01-L-D, and TSS-104-01-L-D—are actively produced by Samtec Inc. and carry ROHS3 compliance with UL94 V-0 flammability certification. The electrical and mechanical specifications are functionally equivalent across all three options, with identical contact pitch, mating dimensions, and operating temperature ranges.

The primary distinction lies in insulation material composition: HTSS-104-01-L-D and HTST-104-01-L-D utilize Liquid Crystal Polymer (LCP), while TSS-104-01-L-D employs Polybutylene Terephthalate (PBT). Both materials meet the specified flammability and compliance requirements. Selection between these parts should be based on existing design documentation, supply chain availability, and any material-specific requirements established in the original circuit design.

Frequently Asked Questions (FAQ)

Q: Can HTST-104-01-L-D replace HTSS-104-01-L-D in an existing design?

A: Yes. Both parts share identical mating pitch (0.100"), contact configuration (8 positions, 2 rows), contact materials, and operating temperature range (-55°C to 125°C). The primary difference is the series designation and insulation material (both LCP), which does not affect functional interchangeability.

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

A: Liquid Crystal Polymer (LCP) and Polybutylene Terephthalate (PBT) are both thermoplastic insulation materials that meet UL94 V-0 flammability requirements. Both materials are suitable for the specified operating temperature range. Material selection should align with the original design specifications and environmental requirements of the application.

Q: Are all three parts suitable for board-to-board and cable applications?

A: HTSS-104-01-L-D and TSS-104-01-L-D are specified for board-to-board or cable applications. HTST-104-01-L-D is specified for board-to-cable/wire applications. Verify application requirements before selection.

Q: Do these connectors have current rating specifications?

A: HTST-104-01-L-D specifies a current rating of 3.4A per contact. Current ratings for HTSS-104-01-L-D and TSS-104-01-L-D are not provided in the available specifications. Consult manufacturer datasheets for complete electrical performance data.

Q: Are all three parts RoHS compliant?

A: Yes. HTSS-104-01-L-D, HTST-104-01-L-D, and TSS-104-01-L-D are all ROHS3 compliant. TSS-104-01-L-D additionally carries REACH Unaffected status.
