The 4.20 mm pitch sets the PCB footprint and the per-contact current ceiling — at 6 A the temperature rise stays within the UL94 V-0 nylon housing limit.
The tin-plated phosphor bronze contacts (mating and post) are rated for a standard number of mating cycles typical of tin finishes; in a low-cycle application like a power supply or appliance interconnect, tin is a cost-effective choice over gold.
The 640499-1 is sourced through independent distribution against your BOM quantity. Submit an RFQ for a real-time quote and lead time.
The 640499-1 mates with a 4-position, 4.20 mm pitch receptacle housing from the same MR series. The latch lock on the header engages the corresponding ramp on the receptacle. Confirm the specific receptacle part number against your wire gauge and terminal requirements.
