Relay Automotive Procurement Notes

Verify the specific suffix 'D' against official CIT documentation to confirm if it denotes a built-in diode or specific terminal configuration, as standard datasheets may not explicitly detail suffix variations. Ensure the required mounting style matches the available PCB pin or quick connect options. Confirm RoHS compliance status for current production batches. Cross-reference the coil resistance tolerance of +/- 10% during circuit design. Validate that the 75VDC maximum switching voltage aligns with the target application's electrical requirements.
