Procurement Notes

Verify that the ordering suffix matches the required tolerance and packaging format. Confirm the manufacturer designation as NextGen Components to ensure authenticity. Check datasheet specifications for insertion loss limits and frequency stability requirements before integration. Ensure handling procedures comply with ESD protection standards for surface mount devices.

Selection Notes

Select this component when a 433.92 MHz SAW resonator with 8-pad compatibility is required. Consider the 5050 footprint constraints during PCB layout design. Evaluate thermal performance needs against the -40°C to +85°C operating range. Compare insertion loss specifications against system sensitivity requirements to ensure adequate signal integrity.

Part Context

This part belongs to the SAR series of SAW resonators from NextGen Components. It shares the same center frequency with other variants like SCR433M920S001 but differs in pad count and package style. The SAR series is optimized for cost-effective mass production while maintaining consistent RF performance characteristics for consumer and industrial electronics.

Replacement Considerations

Direct substitutes may include parts with identical 433.92 MHz frequency and 8-pad configurations. Verify pinout compatibility and mechanical dimensions before substitution. Cross-reference insertion loss and tolerance specs to ensure equivalent circuit behavior. Consult manufacturer cross-reference lists for validated alternative part numbers.
