HTST-117-01-S-DV Equivalent & Substitute Parts

Part Overview

The HTST-117-01-S-DV is a surface mount rectangular connector header manufactured by Samtec Inc. in the Flex Stack series. This 34-position, 2-row connector with 0.100" (2.54mm) pitch is designed for board-to-cable/wire applications with shrouded 4-wall construction and push-pull fastening. The part is active in production with 645 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The N2534-6V0C-RB-WF (3M, 2500 series) qualifies as a substitute for the HTST-117-01-S-DV based on the following alignment of critical parameters:

• Identical connector type (Header), contact type (Male Pin), and position count (34 positions in 2 rows)
• Matching mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
• Identical mounting type (Surface Mount), shrouding configuration (Shrouded - 4 Wall), and fastening type (Push-Pull)
• Equivalent contact finish (Gold mating surface) and material flammability rating (UL94 V-0)
• Both parts maintain RoHS compliance and active product status

Substitution is valid where the specified parameters align. Differences in insulation material, operating temperature range, current rating, and contact length must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-117-01-S-DV and N2534-6V0C-RB-WF are active products with equivalent mechanical and electrical compatibility for standard 34-position, 2.54mm pitch header applications. Selection between these parts should be based on the following factors:

Current capacity requirements determine primary selection. The HTST-117-01-S-DV supports 3.4A per contact, while the N2534-6V0C-RB-WF supports 1.75A per contact. Applications requiring higher current density must use the Samtec part.

Operating temperature range differs between the two parts. The HTST-117-01-S-DV operates from -55°C to 125°C, while the N2534-6V0C-RB-WF operates from -55°C to 105°C. High-temperature applications above 105°C require the Samtec part.

Physical dimensions vary slightly. The HTST-117-01-S-DV has a contact length of 0.250" (6.35mm) and insulation height of 0.350" (8.89mm), while the N2534-6V0C-RB-WF has a contact length of 0.243" (6.17mm) and insulation height of 0.390" (9.91mm). PCB layout and mating connector clearance must accommodate these dimensional differences.

Both parts maintain UL94 V-0 flammability rating and RoHS compliance, suitable for regulated applications. The HTST-117-01-S-DV carries ROHS3 compliance, while the N2534-6V0C-RB-WF carries standard RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the N2534-6V0C-RB-WF directly replace the HTST-117-01-S-DV in all applications?

A: Direct replacement is valid only when application current requirements do not exceed 1.75A per contact and operating temperature does not exceed 105°C. The HTST-117-01-S-DV supports higher current (3.4A) and temperature (125°C maximum). Physical dimensions differ slightly; verify PCB layout compatibility before substitution.

Q: What are the key mechanical differences between these two connectors?

A: Contact length differs by 0.007" (0.18mm), with the HTST-117-01-S-DV at 0.250" and the N2534-6V0C-RB-WF at 0.243". Insulation height differs by 0.040" (1.02mm), with the HTST-117-01-S-DV at 0.350" and the N2534-6V0C-RB-WF at 0.390". These differences may affect mating connector engagement and PCB clearance.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are active products with UL94 V-0 flammability rating and RoHS compliance. The HTST-117-01-S-DV carries ROHS3 compliance. Selection depends on specific application requirements for current capacity, temperature range, and regulatory compliance.

Q: What is the difference in packaging between these parts?

A: The HTST-117-01-S-DV is supplied in Tube packaging, while the N2534-6V0C-RB-WF is supplied in Cut Tape (CT) packaging. Packaging format may affect handling, storage, and automated assembly processes.

Q: Do both connectors support the same mating pitch and row spacing?

A: Yes. Both connectors feature 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing, ensuring mechanical compatibility with standard 2.54mm pitch mating connectors and cable assemblies.
