Product details

46-position mezzanine receptacle, 2.00mm pitch

The 55510-146LF is a 46-position, 2-row board-to-board receptacle from the Minitek 2.00mm series, designed for mezzanine stacking with a 0.079" (2.00mm) pitch. It uses a push-pull fastening type and surface-mount termination, making it suitable for parallel PCB connections in space-constrained assemblies. Rated at 2A per contact and 200V, this receptacle handles signal and low-power duty across general-purpose, industrial, and medical applications.

SMT termination and housing details

The surface-mount termination (Solder) allows reflow assembly directly to the PCB, eliminating through-hole soldering.

Frequently asked questions

What is the pitch of 55510-146LF?

The mating pitch is 0.079" (2.00mm) with an identical row spacing of 0.079" (2.00mm). This is a standard 2.00mm pitch board-to-board receptacle.

Is 55510-146LF RoHS compliant?

RoHS compliance is standard for this series. The part number suffix 'LF' indicates lead-free (RoHS) plating. Verify specific compliance documentation with the manufacturer if required for your region.

What is the current rating of 55510-146LF?

This is a signal-level current; not intended for power distribution.

What is the closest pin-compatible alternative to 55510-146LF?

Within the same Minitek 2.00mm series, the 55510-144LF is a 44-position version. The 55510-146LF has 46 positions; the 44-position variant differs by two circuits. Verify your BOM position count before substituting.
