Based out of Zhejiang, these 43031-0001 terminals are female pin connectors designed specifically for PCB mounting, handling both AC and DC interfaces without issue.

We've been running this model through our workshops for a while now, and teh phosphor bronze with tin plating gives them a solid balance of conductivity and corrosion resistance—better than some plain brass options we've tested.

Most buyers use them in telecommunication or computer boards, but they're honestly not ideal for high-vibration environments unless you add some mechanical locking on your end.


The factory floors about 20,000 square meters total, with 210 employees handling everything form stamping to plating under ISO 9001 and RoHS standard, so compliance paperwork like COAs and REACH declarations are standdard with each shipment.

Free samples of 5-10 pieces are avaliable—just cover shippng—and if you need OEM modifications, the design team can usually turn around custom specs in about 3 days once we nail the tolerances.

Stocked in bags of 1000 or 2000 labeled rolls, but we've shipped smaller packs for trial runs; the 5L drum note is for our other product lines, but the packaging here is pretty flexible depending on your usual order volume.
