Product details

Board-to-Board Receptacle for 20-Position Mezzanine Links

Surface-mount termination with pick-and-place features means this receptacle is ready for automated assembly — no through-hole soldering, no secondary operations.

Comparing 20-Position Options in the Minitek 2.00mm Family

The 55508-120TRLF (20 positions, tape-and-reel) differs from the tube-packaged 55508-120LF only in shipping format — same pitch, plating, and ratings. For a lower circuit count, the 10-position sibling 55508-110TRLF shares the same 2.00mm pitch and gold finish.

Frequently asked questions

What is the mating connector for 55508-120TRLF?

The 55508-120TRLF is a female socket receptacle that mates with a 20-position, dual-row, 2.00mm-pitch male pin header from the Minitek® 2.00mm series. The exact mating part number depends on the required stack height and mounting orientation — a common match is the 55510 series header, but confirm the mating height and keying against your board stack-up.

What is the pitch of 55508-120TRLF?

The mating pitch is 0.079" (2.00mm), with the same 2.00mm row spacing. This sets the PCB footprint for a dual-row, 20-position SMT receptacle.

Are there alternatives to 55508-120TRLF?

The tube-packaged 55508-120LF is electrically identical — same pitch, plating, and 20 positions — differing only in shipping format. For a 10-position version, the 55508-110TRLF shares the same 2.00mm pitch and gold finish. The 55510-120TRLF is a 20-position variant with a different base number; verify mating header compatibility before substituting.
