The 0026644090: All 9 positions are loaded with square tin-plated male pins. For higher mating-cycle duty, a gold-plated sibling would be the better call.
The 0.450" (11.43 mm) mating length gives good wipe on the receptacle contact. Insulation height of 0.446" (11.33 mm) sets the z-height above the PCB — check clearance against nearby components or enclosure lids.
Design engineers validate fit and electrical specs from the official datasheet.
Sourcing buyers need immediate availability from authorized distributors to avoid supply delays.
Commercial buyers compare pricing across distributors to optimize BOM cost.
Maintenance techs or brokers need alternatives if the part is obsolete or unavailable.
Design engineers need pin mapping for circuit integration and footprint validation.
Mechanical compatibility for mating connectors depends on shrouding and lock type.
