Product details

The 66951-020LF: Rated for 1250 V and -65°C to 125°C operation, the connector suits applications in automotive, industrial, medical, and telecommunications equipment where high-voltage isolation and wide temperature range are required. The UL94 V-0 glass-filled polyester housing provides flame resistance for equipment inside an enclosure.

Sizing the board footprint against the 26-position sibling

The 20-position 66951-020LF shares the same single-row layout, 0.100" pitch, 0.142" post length, and 30 µinch gold mating finish as the 26-position 66951-026LF.

Lifecycle and compliance check

The 66951-020LF is listed as Active on the manufacturer's lifecycle status and is RoHS Compliant.

Frequently asked questions

Where can I buy 66951-020LF and how do I get a price?

The 66951-020LF is sourced to order through independent distribution. No stock-holding claim is made; each order is sourced per your BOM.

What is the exact pitch and mating height of 66951-020LF?

The mating pitch is 0.100" (2.54 mm). The insulation height is 0.325" (8.25 mm), which sets the board-to-board spacing when mated with a matching header of the same series.

What is the best equivalent or replacement for 66951-020LF if it is out of stock?

The closest functional equivalent is the 26-position 66951-026LF from the same series — same pitch, plating, and post length. However, the position count differs (20 vs 26), so a board layout change is required.

Is 66951-020LF RoHS compliant?

Yes, the 66951-020LF is RoHS Compliant per the manufacturer's listing.

What are the typical applications for Amphenol 66951-020LF?

The connector is rated for automotive, general purpose, industrial, medical, and telecommunications applications. The 1250 V rating and -65°C to 125°C range suit it for high-voltage isolation and wide-temperature environments.
