Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HTSW-105-23-L-S are identified based on strict equivalence of the following critical parameters:

• 5-position connector header configuration
• 0.100" (2.54mm) mating pitch
• Single-row layout
• Male pin contact type
• Through-hole solder termination
• Square contact geometry
• Gold-plated mating surface with tin-plated post
• Liquid Crystal Polymer insulation material
• UL94 V-0 flammability rating
• Active product status with RoHS compliance

The substitute part 5-146280-5 (TE Connectivity AMP Connectors) meets these core electrical and mechanical requirements, enabling direct functional replacement in applications requiring 5-position 2.54mm pitch header connectors.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-105-23-L-S and 5-146280-5 are active products with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

HTSW-105-23-L-S (Samtec): Suitable for applications requiring the extended upper operating temperature limit of 125°C and the specified contact post length of 0.115" (2.92mm). Natural insulation color may be preferred for visual identification in certain assembly environments.

5-146280-5 (TE Connectivity): Suitable for applications requiring extended lower operating temperature capability to -65°C and breakaway connector functionality. The increased contact finish thickness (15.0µin vs. 10.0µin) on the mating surface provides enhanced wear resistance. Black insulation color offers alternative visual identification.

Both parts meet the core electrical and mechanical requirements for 5-position 2.54mm pitch header applications with identical mating pitch, contact geometry, and termination method.

Frequently Asked Questions (FAQ)

Q: Can the 5-146280-5 be used as a direct replacement for the HTSW-105-23-L-S?

A: Yes. Both parts share identical mating pitch (0.100" / 2.54mm), 5-position configuration, male pin contact type, square contact geometry, gold-plated mating surface, and solder termination. The mechanical and electrical interfaces are compatible for board-to-board or cable applications.

Q: What are the differences in operating temperature ranges?

A: The HTSW-105-23-L-S operates from -55°C to 125°C, while the 5-146280-5 operates from -65°C to 105°C. Selection depends on the specific thermal requirements of the application. The HTSW-105-23-L-S supports higher maximum temperature; the 5-146280-5 supports lower minimum temperature.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist. The insulation height differs (0.100" vs. 0.090"), and contact post length varies slightly (0.115" vs. 0.120"). Overall contact length differs by 0.12mm (11.30mm vs. 11.18mm). These variations are within typical manufacturing tolerances for 2.54mm pitch headers and do not affect standard PCB footprint compatibility.

Q: What is the significance of the breakaway feature on the 5-146280-5?

A: The breakaway feature allows individual positions to be separated from the connector strip. This provides design flexibility for applications requiring custom connector configurations. The HTSW-105-23-L-S does not include this feature.

Q: How do the contact finish thicknesses compare?

A: The HTSW-105-23-L-S has 10.0µin (0.25µm) gold plating on the mating surface, while the 5-146280-5 has 15.0µin (0.38µm). The thicker plating on the 5-146280-5 provides increased durability for high-cycle mating applications. Both meet industry standards for connector reliability.

Q: Are both parts RoHS compliant?

A: Yes. The HTSW-105-23-L-S is ROHS3 compliant, and the 5-146280-5 is RoHS compliant. Both parts meet current regulatory requirements for hazardous substance restrictions.

Q: What packaging differences exist?

A: The HTSW-105-23-L-S is supplied in bag packaging, while the 5-146280-5 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.
