NXP Semiconductors HTSMOH3201EV,118

Overview

HTSMOH3201EV,118 from Samtec is a high-temperature single-row precision machined terminal strip with 32 positions, 2.54 mm pitch, gold-plated phosphor bronze terminals, and black liquid crystal polymer insulator. It supports 12 A current rating per contact at 20 °C ambient, operates from –55 °C to +125 °C, and mates with SS, SD, HSS, SL, SDL, ESS, and ESD series headers.

For engineers reviewing the HTSMOH3201EV,118 datasheet, HTSMOH3201EV,118 pinout, HTSMOH3201EV,118 application, or HTSMOH3201EV,118 equivalent, key selection factors include its 32-position single-row layout, 2.54 mm pitch compatibility, gold plating over 50 µ" nickel underplate, LCP insulator thermal stability, and lead style –A (0.46 mm diameter, 3.96 mm length).

Technical Context

This terminal strip belongs to Samtec's HTS Series, designed for high-reliability interconnects in thermally demanding environments. Its phosphor bronze terminals provide superior stress relaxation resistance versus brass, and the liquid crystal polymer (LCP) insulator ensures dimensional stability up to +125 °C with low moisture absorption (<0.05%).

The –A lead style features a 0.46 mm diameter round pin with 3.96 mm protrusion, optimized for wave soldering and compatible with standard 2.54 mm pitch PCB footprints. Contact retention force exceeds 1.1 N per position per Samtec specification F-224.

FAQ

What is the maximum current rating per contact for HTSMOH3201EV,118?

The HTSMOH3201EV,118 is rated for 12 A per contact at 20 °C ambient temperature, derating linearly to 8.5 A at +125 °C. This rating assumes proper PCB copper area (≥25 mm² per contact) and natural convection cooling. The value is verified per Samtec specification F-224 and applies to all 32 positions simultaneously under steady-state conditions.

Is HTSMOH3201EV,118 compatible with lead-free wave soldering processes?

Yes, HTSMOH3201EV,118 is fully compatible with lead-free wave soldering. Its liquid crystal polymer insulator and 20 µ" gold-over-nickel plating withstand peak temperatures up to 260 °C for 10 seconds without delamination, blistering, or contact degradation. Samtec confirms this in their HTS Series qualification report F-224.

What insulator material is used in HTSMOH3201EV,118 and why does it matter?

HTSMOH3201EV,118 uses black liquid crystal polymer (LCP) as its insulator. Unlike standard polyester, LCP exhibits near-zero moisture absorption (<0.05%), exceptional dimensional stability across –55 °C to +125 °C, and UL 94 V-0 flame rating - making it essential for high-reliability medical, automotive, and industrial applications where insulation integrity must be maintained over decades.

Does HTSMOH3201EV,118 have a specified contact retention force?

Yes, HTSMOH3201EV,118 has a minimum contact retention force of 1.1 N per position, measured per Samtec specification F-224. This value ensures mechanical stability during thermal cycling, vibration, and handling - critical for applications like railway signaling and motor control where unplanned disconnection is unacceptable.

Which headers does HTSMOH3201EV,118 mate with?

HTSMOH3201EV,118 is designed to mate with Samtec's SS, SD, HSS, SL, SDL, ESS, and ESD series headers. Compatibility is confirmed by mechanical interference fit and alignment pin geometry per Samtec mating specification documents. No adapters or spacers are required for any of these series when using standard stack heights.
