44 Positions at 0.100" Pitch — Board Fit and Footprint
The 66953-022: The 44 circuits fill both rows fully — no unloaded positions. The footprint is standard for Dubox™ and BergCon® PV™ headers, so the board layout matches any 44-pin male header in the same series. The 1250V voltage rating is notably high for a 0.100" pitch connector — this part can handle power distribution or isolation barriers where a typical signal-level socket would derate.
Note: this part is listed as RoHS non-compliant. For RoHS-required builds, verify the exemption or seek an alternative finish variant in the Dubox™ family.
Mates with any 0.100" pitch dual-row male header in the Dubox™ or BergCon® PV™ series — confirm the header's pin length and plating match the application's mating cycle requirement. The gold-on-gold interface (30µin on the socket side) provides low and stable contact resistance over many cycles.
