HTSW-101-23-L-S Equivalent & Substitute Parts

Part Overview

The HTSW-101-23-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This single-position, unshrouded header features a vertical orientation with solder termination and push-pull fastening. The connector operates across a temperature range of -55°C to 125°C and is RoHS3 compliant with UL94 V-0 flammability rating.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative contact finishes or post lengths are required for specific applications, or when sourcing from alternative manufacturers offers improved lead times or inventory availability.

Primary Compatibility Criteria:

Single position, single row configuration
Through-hole solder termination
Push-pull fastening mechanism
Square contact shape
Phosphor bronze contact material
UL94 V-0 flammability rating
Moisture Sensitivity Level 1

Variable Parameters Allowing Substitution:

Contact finish type (gold or tin) on mating surface
Contact finish thickness on mating surface
Post length (0.095", 0.115", or 0.120")
Overall contact length (varies with post length)

Engineering Selection Recommendations

Active Status Substitutes (Recommended for New Designs):

The 68001-101HLF and 68001-201HLF from the BERGSTIK® II series offer the closest dimensional match to the HTSW-101-23-L-S with a post length of 0.120" (3.05mm), matching the overall contact length of 0.450" (11.43mm). Both parts are RoHS compliant and maintain the -65°C to 125°C operating range. The 68001-101HLF provides 30.0µin gold finish thickness, while 68001-201HLF offers 15.0µin thickness. Inventory availability is substantial at 12,702 and 6,000 pieces respectively.

The 77311-118-01LF from the BERGSTIK® series provides an alternative with identical post length and overall contact length specifications, with 30.0µin gold finish thickness and 1,174 pieces in stock.

Alternative Post Length Options:

For applications requiring shorter post lengths, the 68000-101HLF and 77311-101-01LF provide 0.095" (2.41mm) post length with 0.425" (10.80mm) overall contact length. These are suitable when PCB thickness or component clearance constraints require reduced post extension.

The 68000-401HLF offers tin contact finish as an alternative to gold, with 100.0µin thickness and 1,558 pieces available.

Obsolete Status Parts (Limited Availability):

The 75160-101-01LF and 75160-118-01LF from the original BERGSTIK® series are marked obsolete. While inventory exists (1,034 and 1,036 pieces), these should be considered only when existing designs mandate compatibility with legacy specifications or when new inventory of active alternatives cannot be sourced.

Frequently Asked Questions (FAQ)

Q: Can I substitute the HTSW-101-23-L-S with a part having a different post length?

A: Yes. Post length variation is an allowed substitution parameter. The HTSW-101-23-L-S has a 0.115" post length. Alternatives with 0.095", 0.100", or 0.120" post lengths are functionally compatible provided the overall contact length and mating contact length remain consistent at 0.230" (5.84mm). Selection depends on PCB thickness and component mounting requirements.

Q: What is the difference between gold and tin contact finishes?

A: Contact finish type is an allowed variable in substitution. Gold finish (10.0µin to 30.0µin thickness) provides superior corrosion resistance and is standard for the HTSW-101-23-L-S. Tin finish (100.0µin thickness) offers cost reduction but requires verification for application-specific corrosion or oxidation requirements. Both finishes maintain electrical performance within specified parameters.

Q: Are BERGSTIK® and BERGSTIK® II series parts interchangeable?

A: BERGSTIK® II represents an updated series with enhanced specifications. Both series meet the core substitution criteria for single-position, through-hole, push-pull headers. BERGSTIK® II parts (68000 and 68001 base numbers) are preferred for new designs due to active product status. Original BERGSTIK® parts (75160 and 77311 base numbers) remain compatible but may have limited availability.

Q: Does contact finish thickness affect electrical performance?

A: Contact finish thickness is a variable parameter in substitution. Thickness variations (10.0µin to 100.0µin) do not affect electrical performance within the specified current and voltage ratings. Selection is based on application requirements for corrosion resistance and contact durability rather than electrical characteristics.

Q: What packaging options are available?

A: The HTSW-101-23-L-S is supplied in bag packaging. Substitute parts are available in bag or bulk packaging. Packaging selection does not affect electrical or mechanical compatibility; it impacts handling, storage, and inventory management only.

Q: Can I use an obsolete part as a substitute?

A: Obsolete parts (75160-101-01LF and 75160-118-01LF) are functionally compatible but carry supply risk. These should be used only when existing designs mandate legacy part compatibility or when active alternatives cannot meet specific dimensional or finish requirements. New designs should specify active status parts.

Q: What is the significance of RoHS and REACH compliance?

A: All substitute parts listed maintain RoHS compliance. REACH status varies; some parts are REACH Affected while others are REACH Unaffected. Compliance verification is required for applications subject to EU regulations. This does not affect functional substitution but impacts regulatory and supply chain considerations.
