HTST-117-01-L-DV-TR Equivalent & Substitute Parts

Part Overview

The HTST-117-01-L-DV-TR is a rectangular connector header manufactured by Samtec Inc., designed for surface mount applications requiring 34-position, 2.54mm pitch interconnection. This shrouded, push-pull fastened header operates across -55°C to 125°C and is actively produced. Substitute parts may be required due to inventory constraints, packaging format preferences, or specific application requirements where alternative mechanical or electrical characteristics remain within acceptable parameters.

Substitute Part Grouping Explanation

The N2534-6V0C-RB-WF from 3M qualifies as a substitute based on the following critical parameters:

Identical connector type (Header) and contact type (Male Pin)
Matching position count (34) and row configuration (2 rows)
Identical mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
Equivalent mounting method (Surface Mount) and shrouding design (Shrouded - 4 Wall)
Matching fastening type (Push-Pull) and termination method (Solder)
Identical contact shape (Square) and flammability rating (UL94 V-0)
Both parts feature keying slots and are actively produced

Substitution is valid where these core parameters align. Differences in contact finish thickness, insulation material composition, and current rating specifications must be evaluated against specific application requirements.

Engineering Selection Recommendations

Both the HTST-117-01-L-DV-TR and N2534-6V0C-RB-WF are actively produced components with UL94 V-0 flammability certification and RoHS compliance. Selection between these parts depends on application-specific constraints:

The HTST-117-01-L-DV-TR supports higher current capacity (3.4A per contact versus 1.75A) and operates to 125°C maximum temperature. The N2534-6V0C-RB-WF operates to 105°C maximum and is supplied in Cut Tape packaging format, which may be preferred for lower-volume assembly operations compared to Tape & Reel format.

Mechanical differences include contact length variance (0.250" versus 0.243") and insulation height differential (0.350" versus 0.390"), which may affect PCB layout and mating clearance requirements. Insulation material composition differs (LCP versus PCT glass-filled), which may influence thermal and mechanical performance in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the N2534-6V0C-RB-WF directly replace the HTST-117-01-L-DV-TR in existing designs?

A: Direct mechanical and electrical substitution is valid for applications where the lower current rating (1.75A versus 3.4A per contact) and reduced maximum operating temperature (105°C versus 125°C) are acceptable. PCB layout must accommodate the 0.040" difference in insulation height and 0.007" difference in contact length.

Q: What are the key differences in packaging between these parts?

A: The HTST-117-01-L-DV-TR is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly. The N2534-6V0C-RB-WF is supplied in Cut Tape (CT) format, appropriate for lower-volume or manual assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. The HTST-117-01-L-DV-TR meets ROHS3 compliance. The N2534-6V0C-RB-WF meets RoHS compliance. Both are suitable for applications requiring lead-free construction.

Q: What is the significance of the insulation material difference?

A: The HTST-117-01-L-DV-TR uses Liquid Crystal Polymer (LCP) insulation, while the N2534-6V0C-RB-WF uses Polycyclohexylenedimethylene Terephthalate (PCT) with glass filler. Both materials achieve UL94 V-0 flammability rating. Material selection affects thermal conductivity, mechanical rigidity, and chemical resistance characteristics specific to the application environment.

Q: Do both parts feature keying slots?

A: Yes. Both the HTST-117-01-L-DV-TR and N2534-6V0C-RB-WF include keying slot features to prevent mating orientation errors.
