A 16-pin, 2.54mm pitch box header with a matching 3A current rating. Verify mechanical fit.
The JILN 321016SG0ABK00A01 is a standard 16-pin, 2.54mm pitch through-hole box header. Several form-fit-function alternatives are available from other manufacturers, offering flexibility in sourcing.
While many parts share the same pitch and pin count, shroud dimensions can vary between manufacturers.
Most alternatives match the 3A current rating, but some are lower and must be avoided if the load is near 3A.
Yes, several potential form-fit-function replacements for the 321016SG0ABK00A01 exist, such as the Nextron Z-231011816106. However, pin-to-pin compatibility is not guaranteed without comparing the mechanical dimensions in the datasheets.
Z-231011816106 and BH254V-16P are strong candidates with matching electrical ratings and connector type. They are considered the best replacement path, pending verification of mechanical drawings.
The primary risk when substituting this connector is a mismatch in mechanical dimensions, such as the shroud height, width, or pin length, which could prevent proper PCB assembly or mating.
