Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-101-23-L-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 2 positions, 2 rows
• Row Spacing: 0.100" (2.54mm) mating spacing
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening
• Contact Finish: Gold-plated mating surface with tin-plated posts
• Insulation Material: Liquid Crystal Polymer (LCP)
• Compliance: ROHS3 compliant, UL94 V-0 rated

The substitute part 5-146256-1 (TE Connectivity AMP Connectors) meets all critical substitution criteria across these parameters, enabling direct functional equivalence in applications requiring 2-position through-hole header connectors with identical mating and termination characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-101-23-L-D and 5-146256-1 are active products with ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications. The primary selection criteria are based on operational temperature range and contact post length specifications.

The HTSW-101-23-L-D operates across -55°C to 125°C, providing extended high-temperature capability. The 5-146256-1 operates across -65°C to 105°C, offering extended low-temperature performance but reduced maximum operating temperature. Contact post length differs by 0.005" (0.13mm), with the 5-146256-1 providing slightly longer posts at 0.120" (3.05mm) versus 0.115" (2.92mm) for the HTSW-101-23-L-D. Contact finish thickness on mating surfaces also varies, with the 5-146256-1 providing 15.0µin (0.38µm) compared to 10.0µin (0.25µm) on the primary part.

Selection between these parts depends on specific application temperature requirements and PCB design constraints related to post length and insertion depth.

Frequently Asked Questions (FAQ)

Q: Can the 5-146256-1 be used as a direct replacement for the HTSW-101-23-L-D?

A: The 5-146256-1 is functionally equivalent for applications operating within the overlapping temperature range of -55°C to 105°C. Both connectors share identical row spacing (0.100" / 2.54mm), mating contact length (0.230" / 5.84mm), and push-pull fastening characteristics. Applications requiring operation above 105°C require the HTSW-101-23-L-D.

Q: What are the key differences between these two 2-position header connectors?

A: The primary differences are operating temperature range, contact post length, and contact finish thickness. The HTSW-101-23-L-D supports -55°C to 125°C operation with 0.115" posts and 10.0µin mating finish. The 5-146256-1 supports -65°C to 105°C operation with 0.120" posts and 15.0µin mating finish. Both use identical row spacing and mating contact geometry.

Q: Are both parts ROHS3 compliant?

A: Yes, both the HTSW-101-23-L-D and 5-146256-1 are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting equivalent regulatory requirements.

Q: Does the difference in contact post length affect PCB design?

A: The 0.005" (0.13mm) difference in post length may impact PCB hole depth and solder fillet characteristics. Applications with tight PCB thickness or specific solder joint requirements should account for this variation during design validation.

Q: What is the significance of the contact finish thickness difference?

A: The 5-146256-1 provides thicker gold plating on mating contacts (15.0µin versus 10.0µin), potentially offering enhanced wear resistance and contact durability in high-cycle mating applications. Both finishes meet standard connector performance requirements.
