HTSW-101-22-L-S Equivalent & Substitute Parts

Part Overview

The HTSW-101-22-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting in board-to-board or cable applications. This single-position, unshrouded header features male pins with gold-plated mating contacts and tin-plated posts, constructed from phosphor bronze with liquid crystal polymer insulation. The connector operates across a temperature range of -55°C to 125°C and maintains UL94 V-0 flammability compliance. With 1025 units currently in stock and active product status, this component serves as a standard interconnect solution for low-density applications requiring reliable push-pull fastening.

Substitute parts become necessary when inventory constraints, manufacturing lead times, or design flexibility requirements necessitate alternative sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The TSW-101-22-L-S qualifies as a direct substitute for the HTSW-101-22-L-S based on alignment across all critical electrical and mechanical parameters. Both connectors share identical specifications for connector type (header), contact type (male pin), position count (1), row configuration (1), mounting method (through hole), termination approach (solder), and fastening mechanism (push-pull).

Physical dimensions remain consistent: contact length at mating interface (0.230" / 5.84mm), post length (0.300" / 7.62mm), overall contact length (0.630" / 16.00mm), and insulation height (0.100" / 2.54mm). Contact geometry, material composition (phosphor bronze), and finish specifications (gold mating surface at 10.0µin thickness, tin post finish) are identical.

Both parts maintain the same operating temperature range (-55°C to 125°C), UL94 V-0 flammability rating, ROHS3 compliance, EAR99 export classification, and HTSUS tariff code (8536.69.4040).

The primary distinction lies in insulation material composition: HTSW-101-22-L-S uses liquid crystal polymer (LCP) with natural color, while TSW-101-22-L-S employs polybutylene terephthalate (PBT) with black color. Both materials satisfy the same flammability and mechanical requirements for this application class.

Parameter Comparison

Engineering Selection Recommendations

Both HTSW-101-22-L-S and TSW-101-22-L-S maintain active product status with full ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on inventory availability and insulation material requirements specific to the application environment.

The HTSW-101-22-L-S with liquid crystal polymer insulation offers superior dimensional stability and lower moisture absorption characteristics. The TSW-101-22-L-S with polybutylene terephthalate insulation provides equivalent electrical and mechanical performance with established long-term reliability in standard industrial applications. Both connectors satisfy identical flammability, temperature, and contact specifications.

Current inventory levels show 1025 units of HTSW-101-22-L-S and 900 units of TSW-101-22-L-S available. Selection may be influenced by supply chain considerations and design documentation requirements for insulation material specification.

Frequently Asked Questions (FAQ)

Q: Are HTSW-101-22-L-S and TSW-101-22-L-S mechanically interchangeable?

A: Yes. Both connectors share identical physical dimensions, contact geometry, mounting footprint, and through-hole termination specifications. They are mechanically interchangeable in board-level applications.

Q: What is the difference between the insulation materials used in these connectors?

A: HTSW-101-22-L-S uses liquid crystal polymer (LCP) insulation, while TSW-101-22-L-S uses polybutylene terephthalate (PBT) insulation. Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range (-55°C to 125°C). LCP offers superior dimensional stability and lower moisture absorption; PBT provides established performance in standard industrial environments.

Q: Do these connectors have different moisture sensitivity levels?

A: HTSW-101-22-L-S is listed as not applicable for moisture sensitivity level. TSW-101-22-L-S carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This distinction does not affect substitution compatibility for standard applications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both HTSW-101-22-L-S and TSW-101-22-L-S are ROHS3 compliant and carry EAR99 export classification.

Q: Can I use TSW-101-22-L-S as a direct replacement for HTSW-101-22-L-S in existing designs?

A: Yes, provided the design does not specify liquid crystal polymer insulation as a requirement. The TSW-101-22-L-S maintains all electrical, mechanical, and thermal specifications necessary for direct substitution in applications designed for the HTSW-101-22-L-S.

Q: What is the contact finish specification for both connectors?

A: Both connectors feature gold-plated mating contacts (10.0µin / 0.25µm thickness) and tin-plated posts. Contact material is phosphor bronze for both parts.
