YART-1A-12DM 12V 30A 4-Pin Mini ISO SPST-NO Automotive Relay,

YART-1A-12DM 12V 30A 4-Pin Mini ISO SPST-NO Automotive Relay, Compatible with 30/85/86/87 Sockets, Cross-Reference 804-1A-12V (1 Form A) for A/C, Fan, Horn, Lighting Circuits
- Specs & Cross-Reference (form/size/function only): 12V DC coil, 30A @ 14V DC (1 Form A, SPST-NO), 4-pin Mini-ISO footprint (30/85/86/87). Cross-reference for identification only: Compatible with Song Chuan 804-1A-C1; Compatible with TE Connectivity F4 (1 Form A) type; Compatible with AZETTLER AZ973 series; Compatible with Picker PC792A/PC792C (verify pin layout and ratings before use).
- Install & Locations: Fits 4-pin Mini-ISO sockets commonly found in fuse/relay boxes. Typical locations/functions include A/C compressor clutch, halogen headlamp, horn, and fog lamp control; wiring uses coil on 85/86 and load 30→87 (NO). Always match socket map and service manual before installation.
- Compatibility Guidance (how to confirm fit): Compatible with vehicles/equipment that specify a 4-pin Mini-ISO SPST-NO (1 Form A) 12V/30A relay. Check: (1) socket has 30-85-86-87; (2) relay size ~27.7×22×29.3 mm; (3) electrical rating meets/ exceeds OEM spec; (4) coil suppression (plain/diode/resistor) requirement. This ensures drop-in replacement without re-pinning.
- Fixes Common Symptoms: Intermittent/no-engagement of A/C clutch, inop horn/fog/aux fan, heat-soak dropout, or burnt contacts in aging relays. Quick test: verify ~12V across 85/86 with command active; confirm continuity 30→87 when energized; replace if contact resistance is high or case heat/discoloration is present. (General troubleshooting for NO Mini-ISO control circuits.)
- Build & Reliability: Silver-tin-oxide (AgSnO) contacts, 10 ms typ operate / 10 ms release, electrical life rated to 100k ops (resistive), mechanical life to 5M ops; operating temp −30°C to +85°C; approx. 35 g body. Designed for automotive environments and compliant with RoHS/ELV per series spec.
- What’s in the Box & Notes: 1× 12V 30A 4-pin Mini-ISO relay. For vehicles requiring 5-pin SPDT (1 Form C) relays or micro-ISO footprints, choose the correct type instead (not included). If your OEM specifies an 804-1A-C1-style or F4-type 1 Form A relay, this unit matches that function/footprint class; always verify coil suppression (plain/diode/resistor) as required by the circuit.
- Complementary Add-Ons (traffic-relevant, not included): 4-pin Mini-ISO relay socket/pigtail harness (12–14 AWG), ATM/ATO fuse taps for add-on circuits, spare 12V Mini-ISO 1 Form A relay for glovebox. Cross-check with Picker PC792 and AZ973 data if you stock multi-brand equivalents to service mixed fleets.
