Product details

20-Pin Board-to-Board Header for Dense Interconnects

The 20021111-00020T4LF is a 20-position, dual-row unshrouded header from Amphenol ICC's Minitek127 series, built for board-to-board stacking on a 1.27mm pitch.

If 20 positions are more than you need, the Minitek127 family includes a 16-position variant (20021111-00016T4LF) and a 14-position variant (20021111-00014T4LF). For more density, the 26-position version (20021111-00026T4LF) shares the same 1.27mm pitch, dual-row layout, gold mating finish, and UL94 V-0 rating — only the pin count changes.

Frequently asked questions

What is the closest functional alternative to 20021111-00020T4LF?

The 26-position version, 20021111-00026T4LF, is the nearest sibling — same pitch, row count, gold mating finish, and UL94 V-0 housing. Only the position count differs.

What is the recommended PCB hole size for this header?

The contact post measures 0.091" (2.30mm) long with a square cross-section. A 0.028" to 0.032" drilled hole is typical for this pin size, but verify against the manufacturer's recommended PCB layout in the product drawing.
