Procurement Notes

Verify the specific manufacturer datasheet for detailed electrical characteristics and reliability data before integration. Confirm that the 6-SMD package footprint matches the design layout. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the part number to confirm availability and authenticity through authorized channels.

Selection Notes

Select this component when a fixed-frequency SAW resonator is required for 868.95 MHz applications. Consider the 50 Ohm impedance match for RF circuit interfaces. Evaluate the ±75 kHz tolerance against system frequency stability requirements. Assess the thermal performance within the specified -40°C to +85°C range for the intended operational environment.

Part Context

This part belongs to the SDR series of SAW resonators from NextGen Components. These components are designed as passive frequency-determining elements in RF circuits. They serve as alternatives to quartz crystals where smaller size and lower cost are prioritized over extreme stability. The series typically covers various industrial and wireless bands.

Replacement Considerations

Direct substitutes must match the 868.95 MHz frequency, 50 Ohm impedance, and 6-SMD package. Verify equivalent insertion loss and tolerance ratings. Check for compatible mounting pads and thermal characteristics. Consult manufacturer cross-reference lists for verified alternative part numbers.
