Replaces / Drop-In Replacement For
This part is a specific value within the RCR32 series. For direct replacement, verify resistance value (620Ω), power rating (1W), and tolerance (±5%) match your original specification. Other RCR32 series values (e.g., RCR32G221JS, RCR32G821JS) are available from distributor stock but cannot interchange without circuit redesign. Verify compatibility with your system integrator before ordering.
Works With
- MIL-R-39008 qualified assemblies and test equipment
- Through-hole soldering and wave-soldering processes
- Standard PCB design tools and CAD libraries
- Industrial automation control modules and I/O boards
