Replacement relay for circuit boards that use OE/Part No. JZC-32F-012-HS3 (manufacturer ordering code: JZC-32F/012-HS3(555)). This is a sealed, through-hole, SPST-NO relay designed for compact PCB layouts.
Coil: 12VDC (approx. 0.45W, ~320Ω)
Contact form: SPST-NO (1 Form A, “H” type)
Rated load (resistive): up to 10A @125VAC, 5A @250VAC, 5A @30VDC
Mounting: through-hole PCB, 4-pin footprint; body approx. 18.4 x 10.2 mm
Switches a higher-current circuit from a low-current control signal on a PCB (application depends on your module/circuit).
Helps restore normal switching when a relay is worn, stuck, or heat-damaged (results vary by circuit condition).
Intermittent output to a load, relay not clicking/switching, stuck ON/OFF, or heat/burn marks near the relay on the board.
This is a PCB-mount relay, not a plug-in blade relay. Replacement typically requires desoldering/soldering.
Confirm match by OE number, board markings, and datasheet: coil voltage, contact form, and pin/footprint must match.
Power off/disconnect battery before service; after soldering, inspect for solder bridges and clean flux residue.
Always confirm fitment by OE number and your vehicle/service manual before purchase.
