Both carry 30.0µin gold plating and the M2.6 flange feature — the only decision variable is whether your BOM calls for 36 or 50 signal lines. If the circuit count fits, the 36-position version is a drop-in swap on the same footprint class; the 50-position version simply occupies more board edge for the extra 14 contacts. ## Mating and Mounting Details Panel-mount flanges with M2.6 hardware secure it to the chassis cutout before soldering, which takes the insertion and extraction stress off the solder joints. The board locks hold the part flat during wave solder. Mates with the matching CHAMP.031 plug — the outer shroud contacts are designed for blind-mating in panel-dress applications where the cable assembly is routed behind a bulkhead.","metaTitle":"TE Connectivity 6658751-1 CHAMP .031 Receptacle, 50 Pos","metaDescription":"TE Connectivity CHAMP .031 receptacle, 50 positions, right-angle solder, gold 30.0µin contacts, shielded with board locks.
