Product details

Board-to-Board Signal Interconnect for 2.00mm Pitch

Rated at 2A per contact and 200V, it handles low-level signal and control circuits within industrial, medical, and general-purpose equipment. Surface-mount termination with a push-pull fastening type.

20-Position vs 24- and 26-Position Siblings

Within the 55510 series, the 55510-120LF (20 positions) is flanked by the 55510-124LF (24 positions) and 55510-126LF (26 positions). For a BOM requiring exactly 20 circuits, the 55510-120LF is the correct fit; the 24- or 26-position variants will not align with a 20-position footprint.

A tape-and-reel variant, 55510-120TRLF, is available for automated pick-and-place assembly — order that suffix if your line runs reels rather than tubes.

Mating Half and Board Layout Considerations

The mated stack height is determined by the header's post length; the receptacle's insulation height is 0.177" (4.50mm). For board layout, the SMT pads follow the 2.00mm grid pattern; the dual-row footprint is symmetrical, so orientation is keyed by the housing's polarization features.

Frequently asked questions

Is 55510-120LF RoHS compliant?

Yes, the 55510-120LF is listed as RoHS Compliant.

What is the mating connector for 55510-120LF?

The exact header part number depends on the required post length and mounting style (through-hole or SMT).

Can 55510-120LF be used as a replacement for 55510-120?

The 55510-120LF is the standard active part number; the 'LF' suffix indicates lead-free / RoHS compliance. If the original 55510-120 (non-LF) is obsolete or non-compliant, the 55510-120LF is the direct RoHS-compliant replacement with the same footprint and ratings.

What is the closest functional second-source to 55510-120LF?

Within the same Minitek® 2.00mm series, the 55510-124LF (24 positions) and 55510-126LF (26 positions) are identical in pitch, plating, and ratings but differ in circuit count. They are not drop-in replacements for a 20-position footprint. For a 20-position requirement, the 55510-120LF remains the direct choice.
