HTSW-104-07-SS-S Equivalent & Substitute Parts

Part Overview

The HTSW-104-07-SS-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 4-position vertical header operates at 0.100" (2.54mm) pitch and is classified as an active product. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct functional replacement in board-to-board or cable connection applications.

Substitute Part Grouping Explanation

Substitute parts for the HTSW-104-07-SS-S are identified based on strict alignment of the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Pitch - mating (0.100" / 2.54mm)
Number of positions (4)
Number of rows (1)
Mounting type (Through Hole)
Termination method (Solder)

Engineering Selection Recommendations

All three parts—HTSW-104-07-SS-S, TSW-104-07-S-S, and HTSW-104-07-SM-S—maintain active product status and full ROHS3 compliance. Selection between these parts is determined by insulation material requirements and availability:

TSW-104-07-S-S employs Polybutylene Terephthalate (PBT) insulation with black color and carries MSL 1 (Unlimited) rating, offering enhanced moisture resistance for applications requiring extended shelf life without desiccant storage.

HTSW-104-07-SS-S and HTSW-104-07-SM-S both utilize Liquid Crystal Polymer (LCP) insulation with natural color and carry MSL Not Applicable rating. These variants are functionally equivalent and differ only in internal design designation (SS vs. SM suffix).

All parts carry identical electrical specifications, mechanical dimensions, contact materials, and thermal operating ranges, supporting direct substitution in applications where insulation material compatibility is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can TSW-104-07-S-S replace HTSW-104-07-SS-S in all applications?

A: Yes, provided the application does not require specific insulation material properties. TSW-104-07-S-S uses PBT insulation versus LCP in the HTSW-104-07-SS-S. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range. The primary difference is moisture sensitivity level: TSW-104-07-S-S carries MSL 1 (Unlimited), while HTSW-104-07-SS-S carries MSL Not Applicable.

Q: What is the functional difference between HTSW-104-07-SS-S and HTSW-104-07-SM-S?

A: These parts are functionally identical. Both use LCP insulation, natural color, and carry MSL Not Applicable. The SS and SM designations reflect internal design variations that do not affect electrical or mechanical performance.

Q: Are all three parts suitable for high-reliability applications?

A: All three parts are ROHS3 compliant, carry UL94 V-0 flammability ratings, and maintain active product status. Selection for high-reliability applications depends on specific insulation material and moisture sensitivity requirements defined by the application specification.

Q: What is the pitch specification for these connectors?

A: All three parts operate at 0.100" (2.54mm) pitch, the standard spacing for this connector family. This pitch is not interchangeable with other spacing standards.

Q: Can these 4-position headers be used in applications requiring different position counts?

A: No. All three parts are fixed at 4 positions in a single row. Applications requiring different position counts require alternative part numbers from the HTSW or TSW series.
