The current rating is not a fixed number — it varies by wire gauge. The header itself is rated for 600VAC/DC, but the actual current capacity depends on the crimp terminal and wire size chosen for the mating half. For a given wire gauge, the temperature rise in the contact interface sets the limit.
The 1723103104 is sourced to order through our independent distribution network. Availability and lead time are confirmed at RFQ against your specific quantity. No stock-holding claim is made; each order is quoted individually.
The current rating varies by wire gauge. The header is rated for 600VAC/DC, but the per-contact current limit depends on the crimp terminal and wire size used in the mating receptacle. Refer to the Ultra-Fit 172310 series application specification for derating curves.
Yes, it is ROHS3 compliant per the manufacturer's status.
