["[MODEL & SPEC CHECK] HF33F 012-ZS3 / HF33F/012-ZS3, 12VDC coil, SPDT / 1 Form C, 5-pin through-hole PCB relay. Printed ratings on the housing: NO 5A 250VAC / 5A 30VDC, NC 3A 250VAC / 3A 30VDC. Confirm part number, coil voltage, pin layout and contact rating before purchase.","[PCB THROUGH-HOLE POWER RELAY] Designed for control boards requiring a compact subminiature intermediate power relay with a standard PCB/THT pin layout. Suitable for replacing a matching HF33F 012-ZS3 style relay in electronic equipment, control panels, appliance boards and DIY repair projects after proper diagnosis.","[SPDT 1 FORM C FUNCTION] 1 Form C changeover contact provides both normally-open and normally-closed paths for low-power control circuits. Use only within the printed electrical ratings; do not install in circuits with a different coil voltage, contact form, pin footprint or load requirement.","[SEALED MINI RELAY BODY] Black rectangular sealed relay body with visible HF33F and 012-ZS3 markings. Compact approx. 20.5 x 10.2 x 15.3 mm package referenced by catalog data. Match the board footprint, pin spacing and relay orientation to the old relay before soldering.","[INSTALLATION NOTES] Power off equipment before service and follow the equipment maker’s safety procedures. Desolder the failed relay carefully, avoid overheating PCB pads, install in the same orientation, and inspect solder joints, traces and nearby components for heat damage or corrosion.","[ONE-PIECE PACK] Includes 1 relay. This is a model-based electrical component listing; equipment brand or model fitment is not claimed. Verify by original relay marking, PCB footprint, schematic, datasheet and technician diagnosis before use."]
