Specs & key features: OE#JZC-40F-012-HS electromechanical power relay, 12VDC coil, 4-pin DIP-4 PCB mount (through-hole), SPST-NO (1 Form A) contact. Reference load rating: up to 5A (resistive); reference switching limits up to 250VAC/24VDC (confirm on your schematic and load type). Board-level switching for control circuits and relay modules; reference spec lists -40°C to +85°C operating range, 10M mechanical life / 100k electrical life (at rated load). Reference cross/series seen in documentation: JZC-40F / JZC-32F / H32F family—match footprint, coil voltage, contact arrangement, and rating before ordering.
Install/replace tips: Power OFF and disconnect the battery/power source before service. Confirm the PCB marking and footprint match JZC-40F-012-HS (DIP-4) and that your circuit uses a 12VDC coil—do not substitute 5V/9V/24V coils. Desolder the old relay, clean pads, then solder the new relay squarely; inspect for bridges/cold joints. Typical install location is board-level (inside an electronic control module, relay control module, or relay board), not a plug-in cube socket. After installation, bench-test: apply 12V to the coil pins and verify click + continuity across the contact pins. Confirm pin layout and contact rating against the schematic/vehicle manual.
Compatible with 12VDC PCB assemblies that explicitly call out OE#JZC-40F-012-HS on the silkscreen or BOM (DIP-4, SPST-NO, through-hole) Relay. Use-case keywords: PCB power relay, relay control module, board-level relay replacement, electromagnetic relay for 12V control circuits. Best practice: match coil voltage (12V), contact form (1 Form A), pin spacing/outline, and the load rating required by your circuit. If your board does not list the part number, confirm by removing the old relay and checking its marking + footprint before ordering.
Compatible with control boards and power boards where the JZC-40F family relay is used for low-to-mid current switching Relay. Reference documentation for the relay family lists typical applications such as HVAC controls, home appliance control boards, power systems, and office equipment (application depends on your device). This listing is for the 12V coil version (012); always verify coil voltage, contact rating, and PCB footprint with your service manual or the removed relay before purchase to avoid wrong-coil or wrong-footprint returns.
Compatible with board-level 12V relay replacement jobs where space is limited and a DIP-4 SPST-NO relay is required Relay. Helps address common symptoms related to a worn relay in a control circuit: intermittent power to a load, relay that clicks but has unstable contact, or relay that does not actuate under normal coil voltage (symptoms vary; diagnosis required). For best results, verify the driving voltage at the coil pins, check solder joints/traces, and confirm the controlled load does not exceed the relay's rated current for your application.
Compatible with related search/maintenance parts (not interchangeable): JZC-40F-024-HS (24V coil) or JZC-40F-005-HS (5V coil) Relay—use these only if your original relay marking and schematic specify that coil voltage. If you service multiple boards, keeping the correct coil-voltage variants as spares can reduce downtime; always match the exact marking/footprint and confirm contact rating in the device documentation. Tip: replacing a heat-stressed relay may also require reflowing nearby cracked solder joints and checking the driving transistor/diode on the board (per your repair guide).
وصف
This listing is for a board-level electromechanical relay identified by the marking JZC-40F-012-HS. It is designed for switching loads in 12V control circuits when installed on a compatible PCB.
Part/ID: JZC-40F-012-HS (012 = 12VDC coil)
Mounting: Through-hole PCB mount, DIP-4 footprint
Contact form: SPST-NO (1 Form A)
Reference ratings: up to 5A (resistive); reference switching limits up to 250VAC/24VDC
Reference environment: -40°C to +85°C; reference life 10M mechanical / 100k electrical (at rated load)
Restores reliable switching in relay control modules and PCB power boards where an identical relay is specified
Useful for maintenance/repair when the original relay is heat-stressed, worn, or has unstable contacts
Intermittent power to a load, delayed switching, or a relay that clicks but does not pass current consistently
No actuation when correct coil voltage is present (could also be a driver or solder-joint issue)
Fitment reminder: Do not rely on vehicle make/model alone. Confirm fitment by OE marking (JZC-40F-012-HS), coil voltage (12V), contact form (SPST-NO), and PCB footprint/pin spacing using your service manual or by inspecting the removed relay.
Installation note: Disconnect power before service. Verify pin layout and contact rating against your schematic, then bench-test after installation (apply 12V to the coil pins and verify contact continuity).
