HTST-120-01-LM-DV Equivalent & Substitute Parts

Part Overview

The HTST-120-01-LM-DV is a surface mount rectangular connector header manufactured by Samtec Inc., designed for board-to-cable/wire applications. This 40-position, 2-row connector operates across -55°C to 125°C and features gold-plated mating contacts with a 0.100" (2.54mm) pitch. The part is Active in product status with 776 units currently in stock. Substitute parts are identified to address inventory availability, series preference, or application-specific requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 40
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Contact Length - Mating: 0.250" (6.35mm)
• Insulation Height: 0.350" (8.89mm)
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The identified substitutes HTST-120-01-L-DV and HTSS-120-01-L-DV maintain all critical electrical and mechanical parameters. Differences exist only in series designation (HTST vs. HTSS), fastening type specification, and application scope, which do not affect functional interchangeability in standard board-to-cable/wire connection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—HTST-120-01-LM-DV, HTST-120-01-L-DV, and HTSS-120-01-L-DV—are Active products manufactured by Samtec Inc. and maintain ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts should be based on:

1. Series requirement: HTST series parts (HTST-120-01-LM-DV and HTST-120-01-L-DV) are functionally identical and interchangeable. The HTSS-120-01-L-DV represents an alternative series within the Flex Stack family.

2. Inventory availability: HTST-120-01-L-DV offers the highest stock level at 1404 units, followed by HTSS-120-01-L-DV at 1028 units, and HTST-120-01-LM-DV at 776 units.

3. Application scope: The main part and HTST-120-01-L-DV are specified for board-to-cable/wire applications, while HTSS-120-01-L-DV is specified for board-to-board or cable applications, providing broader compatibility.

All three parts satisfy identical electrical and mechanical requirements for standard connector header applications.

Frequently Asked Questions (FAQ)

Q: Are HTST-120-01-LM-DV and HTST-120-01-L-DV directly interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications, including pitch, contact count, mating contact length, insulation height, material composition, and operating temperature range. The difference in part number designation does not affect functional compatibility.

Q: Can HTSS-120-01-L-DV replace HTST-120-01-LM-DV in a board-to-cable/wire application?

A: Yes. HTSS-120-01-L-DV maintains all critical connector parameters required for board-to-cable/wire connections. The series designation change reflects a different product line within Samtec's Flex Stack family but does not compromise electrical or mechanical compatibility for this application class.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters remain constant: connector type (Header), contact type (Male Pin), position count (40), row count (2), mating pitch (0.100"), row spacing (0.100"), mounting type (Surface Mount), termination method (Solder), shrouding configuration (Shrouded - 4 Wall), mating contact length (0.250"), insulation height (0.350"), contact finish (Gold), contact material (Phosphor Bronze), insulation material (LCP), and operating temperature range (-55°C to 125°C).

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and carry UL94 V-0 flammability certification. All are Active products with no known end-of-life status.

Q: Which part should be selected for new designs?

A: Selection should be based on series preference and inventory availability. HTST-120-01-L-DV offers the highest stock level and maintains the same series as the original part. HTSS-120-01-L-DV provides an alternative series option with comparable availability.
