Board Fit and Current Budget
The 57202-F52-05ALF: This is a 10-position, dual-row header on 2.00mm pitch — the row spacing is also 2.00mm, so the total footprint is a 2x5 grid that fits a tight board layout.
Plating and Mating Cycle Trade-off
This provides corrosion protection for occasional mating, but the cycle life is lower than the 15µin or 30µin gold on siblings like 57202-S52-04ALF or 57202-G52-04ALF. For a board-to-board interconnect that is mated once at assembly and rarely disconnected, the flash gold is adequate. For repeated field servicing, step up to the thicker gold variants. The post thickness is standard for SMT headers in this pitch class.
This header mates with Minitek 2.00mm receptacles (female socket housings) from the same series. Termination is solder-only — surface-mount to the PCB pads. No press-fit or wire-crimp option; the board footprint must match the 2.00mm pitch and the 2x5 grid.
