HTSW-120-23-G-D-LL Equivalent & Substitute Parts

Part Overview

The HTSW-120-23-G-D-LL is an active rectangular connector header manufactured by Samtec Inc. This through-hole mounted connector features 40 positions arranged in 2 rows with 0.100" (2.54mm) pitch, designed for board-to-board or cable interconnection applications. The connector utilizes kinked pin solder termination with push-pull fastening and is constructed with Liquid Crystal Polymer (LCP) insulation and phosphor bronze contacts finished in gold. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate alternative packaging or material specifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-120-23-G-D-LL is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - mating (0.100" / 2.54mm)
• Number of positions (40)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Kinked Pin, Solder)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Contact material (Phosphor Bronze)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The TSW-120-23-G-D-LL meets all critical substitution criteria. Variations in insulation material (LCP versus PBT), insulation color, packaging format, and moisture sensitivity level do not affect functional or mechanical compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-120-23-G-D-LL and TSW-120-23-G-D-LL are active products from Samtec Inc. with identical electrical and mechanical specifications for mating interface, contact geometry, and termination characteristics. Both connectors maintain ROHS3 compliance and UL94 V-0 flammability certification.

The TSW-120-23-G-D-LL is available in bulk packaging with higher inventory levels (1000 pcs) compared to the HTSW-120-23-G-D-LL (607 pcs). The insulation material differs between the two parts: the HTSW series uses Liquid Crystal Polymer (LCP) while the TSW series uses Polybutylene Terephthalate (PBT). Both materials meet the specified flammability and temperature requirements. The TSW-120-23-G-D-LL carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Selection between these parts should be based on packaging requirements, material preference, and supply availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Are the HTSW-120-23-G-D-LL and TSW-120-23-G-D-LL mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (40), row configuration (2 rows), contact geometry (square male pins), and overall dimensions. They are mechanically interchangeable in board-to-board and cable applications.

Q: What is the difference in insulation material between these parts?

A: The HTSW-120-23-G-D-LL uses Liquid Crystal Polymer (LCP) insulation, while the TSW-120-23-G-D-LL uses Polybutylene Terephthalate (PBT). Both materials satisfy the UL94 V-0 flammability requirement and operate across the -55°C to 125°C temperature range. Material selection depends on specific application requirements and design preferences.

Q: Does the difference in packaging affect compatibility?

A: No. Packaging format (bulk versus other formats) does not affect the electrical or mechanical performance of the connector. Packaging differences relate only to order quantity, handling, and supply chain logistics.

Q: Are both parts RoHS compliant?

A: Yes. Both the HTSW-120-23-G-D-LL and TSW-120-23-G-D-LL are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What does MSL 1 (Unlimited) mean for the TSW-120-23-G-D-LL?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the TSW-120-23-G-D-LL has no moisture sensitivity constraints. The component can be stored and handled without special moisture control measures, providing greater flexibility in supply chain management compared to parts with higher MSL ratings.

Q: Can I use either part in high-temperature applications?

A: Yes. Both connectors are rated for continuous operation from -55°C to 125°C, making them suitable for standard industrial and commercial temperature environments within this range.
