HTST-108-01-L-DV-TR Equivalent & Substitute Parts

Part Overview

The HTST-108-01-L-DV-TR is a surface mount rectangular connector header manufactured by Samtec Inc. in the Flex Stack series. This 16-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 currently active in production with 1780 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTST-108-01-L-DV-TR is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (16)
• Number of rows (2)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Termination method (Solder)
• Contact finish - mating (Gold)
• Material flammability rating (UL94 V-0)
• RoHS compliance status

The substitute part N2516-6V0C-RB-WD from 3M meets all mandatory parameters. Variations in contact material (Copper Alloy vs. Phosphor Bronze), insulation material (PCT Glass Filled vs. LCP), contact finish thickness, current rating, and operating temperature maximum are within acceptable tolerance ranges for this connector category and do not preclude functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTST-108-01-L-DV-TR and N2516-6V0C-RB-WD are active production parts with UL94 V-0 flammability certification and RoHS compliance. Selection between these parts should be based on the following engineering considerations:

HTST-108-01-L-DV-TR (Samtec): Supports higher current per contact (3.4A) and extended operating temperature range to 125°C. Recommended for applications requiring maximum thermal headroom or higher current density.

N2516-6V0C-RB-WD (3M): Rated for 1.75A per contact with operating temperature range to 105°C. Suitable for standard-current applications within the specified temperature envelope. Features thicker gold plating (30.0µin vs. 10.0µin) on mating contacts, providing enhanced wear resistance in high-cycle mating applications.

Both parts are packaged in Tape & Reel format and are suitable for automated assembly processes. The 3M part includes pick-and-place feature designation.

Frequently Asked Questions (FAQ)

Q: Can N2516-6V0C-RB-WD be used as a direct replacement for HTST-108-01-L-DV-TR?

A: Yes, for applications operating within the N2516-6V0C-RB-WD specifications. The substitute part matches all critical mechanical and electrical parameters. However, verify that your application current requirements do not exceed 1.75A per contact and that the maximum operating temperature does not exceed 105°C.

Q: What is the difference in contact finish thickness, and does it matter?

A: The N2516-6V0C-RB-WD has 30.0µin (0.76µm) gold plating on mating contacts compared to 10.0µin (0.25µm) on the HTST-108-01-L-DV-TR. Thicker plating provides extended contact life in high-cycle mating environments and improved corrosion resistance. For standard-use applications, both thicknesses meet industry durability standards.

Q: Are there differences in insulation material, and which is better?

A: The HTST-108-01-L-DV-TR uses Liquid Crystal Polymer (LCP), while the N2516-6V0C-RB-WD uses glass-filled Polycyclohexylenedimethylene Terephthalate (PCT). Both materials achieve UL94 V-0 flammability rating. LCP offers superior dimensional stability; glass-filled PCT provides enhanced mechanical strength. Material selection depends on specific application requirements for thermal stability or mechanical stress.

Q: What is the significance of the 0.007" (0.18mm) difference in contact length?

A: The mating contact length difference (0.250" vs. 0.243") is within standard tolerance for this connector category and does not affect functional compatibility. Both parts are designed for equivalent mating depth and engagement force.

Q: Can these parts be mixed in the same assembly?

A: Both parts are compatible with the same mating connectors due to identical pitch, row spacing, and contact geometry. However, mixing parts in a single assembly is not recommended due to variations in insulation height (0.350" vs. 0.390") and contact finish thickness, which may result in inconsistent mating force and contact pressure across the connector array.

Q: Are both parts available in the same packaging format?

A: Yes. Both HTST-108-01-L-DV-TR and N2516-6V0C-RB-WD are supplied in Tape & Reel (TR) packaging suitable for automated pick-and-place assembly equipment.
