F5H-DC12V-P1 12V Relay, Replacement for DYSF-D12V-P2 for Appliance Control Boards16A 250VAC SPST-NO, PCB Mount with 2 Tabs + 3 Pins,

DYSF-D12V-P1 12VDC PCB Relay – 16A 250VAC, 1 Form A (SPST-NO) Compact, sealed power relay for appliance control boards and other low-voltage–controlled AC loads. Typical use includes switching heater/magnetron or fan circuits on microwave oven PCBs and similar equipment. Match the code on your original part (DYSF-D12V-P1 / F5H-DC12V-P1) and verify coil voltage and footprint before purchase.

• Specs & cross-refs: DYSF-D12V-P1 (aka F5H-DC12V-P1); coil 12VDC; 1 Form A (SPST-NO); contact rating 16A @ 250VAC; typical coil resistance ≈360Ω (≈33 mA at 12V); pick-up ≈9V; release ≈1.2V; compact sealed PCB relay with 5-pin layout (2 quick-connect tabs on top + 3 PCB pins on bottom). Built for switching heater/magnetron or fan loads and other AC mains devices in low-voltage-controlled equipment.
• Installation & location: typically mounted on the appliance control PCB near the mains output section. Disconnect power and discharge the HV capacitor before service. Desolder the old relay from the board, match pin orientation, and solder the new part; connect the two top quick-connect tabs to the load terminals as on the original. Verify the control signal is 12VDC, check coil resistance ≈360Ω, and confirm the board trace spacing/clearance suits 16A/250VAC before returning to service.
• Compatibility: Compatible with control boards and appliances calling for a 12VDC coil, 1 Form A (SPST-NO) relay rated up to 16A @ 250VAC; Compatible with microwave-oven heater/magnetron or fan relay positions on PCB assemblies; Compatible with projects and industrial controls that need a compact 5-pin relay with 2 top quick-connect tabs + 3 PCB pins; verify by matching the code on your old part (Compatible with DYSF-D12V-P1 / F5H-DC12V-P1).
• What issues it can help solve: no-heat condition due to an open heater/magnetron relay; intermittent heating or fan operation from worn contacts; buzzing/arcing from a pitted relay; heat that stays on because a relay is stuck closed. If diagnostics confirm the original relay is faulty and coil drive is correct (≈12VDC), replacing it with this unit can restore switching reliability and protect the board from overheated traces caused by high contact resistance.
• Complementary items (sold separately): Compatible with high-voltage microwave fuses, door interlock micro-switches, HV diode/capacitor kits, turntable motors, and thermal cutouts/thermostats commonly serviced together. Use only components that are Compatible with your appliance model and ratings; always match part codes, contact ratings (≥16A/250VAC), and coil voltage (12VDC) to avoid mis-fit or unsafe operation.
• Fitment verification tips: some assemblies are marked DYSF-D12V-P2; market listings indicate DYSF-D12V-P1 may replace DYSF-D12V-P2 on boards sharing the same footprint and terminal style. To ensure compatibility, confirm: identical 5-pin layout (2 top quick-connect tabs + 3 PCB pins), 12VDC coil, and 16A/250VAC contact rating. When in doubt, compare measurements and datasheets or consult a qualified technician.
