Procurement Notes

Verify the specific manufacturer designation, as Electrocube products may be distributed under related brand names such as SEACOR or Radwell. Confirm lead compatibility and voltage ratings against original equipment specifications before integration. Ensure the component matches the required 22 Ohm resistance and 0.5 µF capacitance values for the intended circuit application.

Selection Notes

Select this component for applications requiring compact, through-hole RC filtering solutions. The radial lead format facilitates easy installation on standard PCBs. Consider the 600 VDC rating when designing for higher voltage DC lines or peak AC voltages. Verify thermal constraints within the -40°C to 80°C range for the specific operational environment.

Part Context

The RG1784-1 belongs to the Electrocube RG1784 series of single-phase RC networks. This series offers various resistance and capacitance combinations tailored for different EMI filtering requirements. The components are characterized by their small footprint and robust construction, suitable for industrial and commercial electronic assemblies requiring reliable noise reduction.

Replacement Considerations

Direct substitutes include other single-phase RC networks with identical 22 Ohm and 0.5 µF specifications. Verify physical dimensions and lead spacing to ensure mechanical compatibility. Cross-reference part numbers such as those from SEACOR if available, ensuring electrical parameters match exactly.
