SPECIFICATIONS & REFERENCES — Model: HK19F-DC12V-SHG; contact form: DPDT (2C); contact rating: 1A 125VAC / 2A 30VDC; coil: 12V DC, 0.2W (code H), 720Ω @20°C; operate ≤6ms, release ≤4ms; insulation 100MΩ (500VDC); dielectric 1000VAC (coil-contact) / 600VAC (contact-contact); footprint: 8-pin DIP, 20.2×10.0×12.0 mm; interchange/ref within the same code family: HK19F-12V (2C, sealed), HK19F-DC12V-S, HK19F-DC12V (RoHS code G)
INSTALLATION & LOCATION — PCB mount, through-hole DIP (bottom-view 8-pin layout per datasheet). Use on control boards where the silkscreen/part marks “HK19F…2C.” Drive the coil from a suitable transistor/driver stage; add a flyback diode across the coil; observe the orientation notch; sealed plastic case supports wave soldering/board cleaning.
COMPATIBILITY — Compatible with PCBs designed for the HK19F 2C 8-pin footprint and 12V-H coil; fits assemblies that specify HK19F-DC12V-SHG or the same family markings. Not compatible with plug-in blade automotive relays (30/40A ISO mini). Always match coil voltage and pinout on the original relay before ordering.
PERFORMANCE — Silver-alloy bifurcated contacts; max switching power 125VA/60W; max switching voltage 250VAC / 125VDC; contact resistance ≤100 mΩ (at 1A 6VDC); mechanical life 10,000,000 ops; electrical life 100,000 ops (resistive load); operating temp −30°C to +70°C; vibration 10–55 Hz/1.5 mm; shock 10 g functional.
TYPICAL USES — Low-power switching in security, instrumentation, smart-home, vending/industrial boards, audio/test jigs, and other 12V control circuits; suitable for small loads within rating (≤2A @30VDC). (Select contact protection for inductive loads.)
COMPLEMENTARY ITEMS — Compatible with same-footprint coil-voltage variants when the design requires them: HK19F-DC5V-SHG, HK19F-DC24V-SHG; pairs with 8-pin DIP relay sockets/adapters, driver modules, and flyback diodes. Match footprint + coil code for drop-in replacement.
COMPLIANCE & HANDLING NOTES — Plastic-sealed type (code S) and RoHS (code G); epoxy-sealed for wave soldering/cleaning; do not ultrasonically clean; allow cooling below 40 °C before washing; avoid strong magnetic fields. Verify board space and clearance: ~20.2×10.0×12.0 mm, ~5 g.
