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

Part Overview

The HTST-108-01-T-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 and features shrouded 4-wall construction with push-pull fastening. The part is currently active in production with 789 units in stock. Alternative parts may be required due to supply constraints, design revisions, or specific application requirements that demand different electrical or mechanical characteristics.

Substitute Part Grouping Explanation

Substitution of the HTST-108-01-T-DV-TR is permissible when the alternative part maintains the following critical parameters:

16-position, 2-row configuration
0.100" (2.54mm) mating pitch and row spacing
Surface mount termination with solder connection
Shrouded 4-wall construction
Push-pull fastening mechanism
Operating temperature range of -55°C ~ 105°C minimum
UL94 V-0 flammability rating
RoHS compliance

The N2516-6V0C-RB-WD from 3M meets these core substitution criteria. Variations in contact finish, insulation material, contact length, and current rating are secondary parameters that may affect performance in specific applications but do not preclude functional substitution when the primary mechanical and electrical envelope requirements are satisfied.

Engineering Selection Recommendations

Both the HTST-108-01-T-DV-TR and N2516-6V0C-RB-WD are active production parts with UL94 V-0 flammability ratings and RoHS compliance. The primary distinction lies in current-carrying capacity: the Samtec part supports 3.4A per contact, while the 3M substitute supports 1.75A per contact. Selection between these parts should be based on the application's current requirements. The Samtec part is suitable for higher-current applications, whereas the 3M part is appropriate for standard-current or lower-current signal applications. Both parts are available in tape and reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

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

A: Yes, for applications where the current requirement does not exceed 1.75A per contact. Both parts share identical mating pitch, row spacing, position count, mounting type, shrouding, and fastening mechanism. The mechanical footprint and electrical interface are compatible.

Q: What is the significance of the different contact finishes (Tin vs. Gold)?

A: Contact finish affects corrosion resistance and mating force characteristics. The gold-plated contacts on the 3M part provide superior corrosion resistance in harsh environments, while the tin-plated contacts on the Samtec part are suitable for standard industrial applications.

Q: Are there dimensional differences that could affect PCB layout?

A: Yes. The N2516-6V0C-RB-WD has a greater insulation height (0.390" vs. 0.350") and slightly shorter mating contact length (0.243" vs. 0.250"). These differences may require verification against specific board-level clearance and mating depth requirements.

Q: What does the difference in current rating mean for my application?

A: The HTST-108-01-T-DV-TR supports 3.4A per contact, while the N2516-6V0C-RB-WD supports 1.75A per contact. If your application requires current delivery exceeding 1.75A per contact, the Samtec part is the appropriate choice. For signal-level or lower-current applications, both parts are functionally equivalent.

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

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

Q: What is the difference in insulation material, and does it matter?

A: The Samtec part uses Liquid Crystal Polymer (LCP), while the 3M part uses glass-filled Polycyclohexylenedimethylene Terephthalate (PCT). Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range. Material selection is typically driven by manufacturing process compatibility and cost considerations rather than functional performance differences in standard applications.
