AZ9731-1C-12DC4 Mini-ISO Automotive Relay — 12V SPDT 40/30A (5-Pin)This 5-pin changeover relay follows the Mini-ISO footprint for broad automotive use. It provides dependable switching for high-current 12 V circuits when an SPDT (1 Form C) relay is specified.Key SpecificationsContact form: SPDT (1 Form C), 5 pins (30, 85, 86, 87, 87a)Ratings: 40 A (NO) / 30 A (NC) @ 14 V DC; max switching voltage 75 V DCCoil: 12 V, 90 Ω (≈ 133 mA), ~1.6 W; must operate 7.8 V; must release 1.8 VTerminals: 0.250 in (6.3 mm) quick-connect bladesOperating temperature: −40 °C to +125 °CHousing: C4 case — shrouded cover with metal mounting bracketWiring & Pinout85 & 86: coil terminals (observe polarity only if a suppression diode is present)30: common (battery feed)87: normally open (NO) output87a: normally closed (NC) outputInstallation LocationsTypically installs in the engine-bay or under-dash relay/fuse block using a Mini-ISO cavity. Use the integrated steel bracket to secure. Confirm the cavity and function using the fuse-box cover diagram.Typical UsesA/C compressor clutch, engine/cooling fansHeadlamps/lighting, hornFuel pump, starter control (as specified by the vehicle circuit)Interchange / Cross NumbersCompatible with Mini-ISO SPDT 5-pin 12 V part numbers (verify ratings, pinout, and case/bracket before purchase): G8JN-1C6T-F-R-DC12; 896H-1CH-D1SW; VF4 12 V; HFV4 12 V.Complementary AccessoriesRelay sockets/housings: Compatible with ST9721-U1 / ST9721-U2 / ST9721-U30.250 in receptacle terminals: Compatible with 5-160526-9 / 5-160558-9Note: Match by OE number and 5-pin SPDT layout (85/86, 30, 87, 87a). Compare to the diagram on your fuse-box cover for a perfect drop-in fit.

• Specs + OE interchange — 12V coil (90 Ω ≈ 1.6 W); SPDT (1 Form C) 5-pin; contacts 40 A (NO) / 30 A (NC) @14 V; max switched 75 V DC; operate 7.8 V, release 1.8 V; −40 °C to +125 °C; 0.250 in (6.3 mm) quick-connect blades; C4 case (shrouded cover, metal bracket). Compatible with G8JN-1C6T-F-R-DC12; 896H-1CH-D1SW; VF4 12V; HFV4 12V (verify pinout 30/85/86/87/87a before purchase).
• Installation & location — Fits Mini-ISO relay cavities in engine-bay or under-dash fuse/relay blocks; use the integrated steel bracket for secure mounting. Coil on 85/86 (polarity only matters when a suppression diode is present); common on 30; outputs on 87 (NO) and 87a (NC). Push fully into the socket; avoid bending terminals; confirm cavity function on the fuse-box diagram.
• Fitment method without guesswork — This model follows the Mini-ISO SPDT 5-pin footprint used across many passenger cars & light trucks. Match by your original relay’s OE number, pin layout (85/86, 30, 87, 87a), and case/bracket style (C4) to ensure drop-in compatibility. Use the printed cavity map on the vehicle’s fuse-box cover for final confirmation.
• Fixes common faults — Restores reliable switching when a worn/stuck relay causes no-A/C compressor engagement, inoperative cooling/engine fans, headlamp/lighting issues, horn failure, intermittent fuel-pump power, or starter-control glitches in circuits designed for a 5-pin SPDT relay.
• Complementary accessories for a clean install — Pair with Mini-ISO relay sockets/housings and receptacle connectors (Compatible with ST9721-U1 / ST9721-U2 / ST9721-U3 sockets; Compatible with 5-160526-9 / 5-160558-9 0.250 in receptacles; sold separately). These accessories improve serviceability, retention, and heat management under high loads.
