Use these specifications to identify your BOM line. MZZ confirms availability, quantity and delivery against your purchasing requirement.
- Nominal coil
- 12 VDC
- Contact arrangement
- 1 Form A (SPST-NO)
- Construction
- Plastic sealed
- Contact material
- AgSnO2
Why the complete code matters
Keep the T and F characters in the inquiry. A 1Z changeover version has different normally-open and normally-closed load conditions; check the wiring and load duty rather than treating it as the same device.
Where the HF3FF family may fit
These are family-level screening examples. Final suitability depends on the exact load, environment, required life and approvals.
- Appliance and equipment control after reviewing the exact resistive, inductive or inrush load rating
- Industrial PCB switching where contact arrangement, coil drive and thermal conditions are verified
- Maintenance BOM sourcing with the original manufacturer code and drawing revision preserved
What MZZ verifies before quoting
The original BOM code remains unchanged while commercial and technical conditions are checked.
- Full manufacturer ordering code and every suffix
- Coil voltage, polarity and switching or latching drive
- Contact arrangement, switching load and electrical-life requirement
- PCB terminals, land pattern, enclosure and packing format
- Required quantity, destination, target date and documentation
