Product details

Board-Fit and Routing Density

Current and Mating-Cycle Limits

The tin bismuth contact finish (39.4 µinch thick) is rated for 20 mating cycles. In a product that mates once at assembly and sees only occasional rework, that cycle life is sufficient. For applications requiring frequent field disconnect, a gold-plated sibling in the Easy-On FS19 family would extend reconnect duty.

ZIF Flip-Lock and Solder Retention

Comparison with 5052785032

If your BOM calls for 40 circuits, the 5032 is a drop-in alternative with the same footprint length scaled to 40 positions. For 50 circuits, the 5033 is the correct pick.

Frequently asked questions

What is the closest pin-compatible alternative to 5052785033 in the Easy-On FS19 family?

Within the same series, the 5052785032 is a 40-position variant with identical pitch, ZIF lock, and plating. For a 50-position drop-in, no direct equivalent exists outside the 505278 base number — the 5033 is the standard 50-position option.
