Procurement Notes

Verify the specific ordering suffix against official IQD documentation to confirm exact packaging and handling specifications. Ensure the selected variant matches the required 4-SMD no-lead form factor and temperature rating. Cross-reference the datasheet parameters for ESR and load capacitance to guarantee compatibility with the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a 25 MHz reference with tight ±10 ppm tolerance is required for surface mount assembly. The 8 pF load capacitance must align with the host oscillator circuit requirements. Consider the -40°C to +125°C operating range for applications exceeding standard commercial temperature limits. Verify that the 100 Ohm ESR value is acceptable for the intended power consumption and drive level constraints.

Part Context

This part belongs to the IQXC-42 series of quartz crystals from IQD Frequency Products. It represents a standard industry solution for surface mount oscillators. The product line emphasizes robust construction through resistance welding and inert atmosphere sealing. This specific model addresses the need for high-frequency stability in compact electronic designs.

Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 8 pF load capacitance, and 4-SMD no-lead package dimensions. Verify equivalent ESR values and temperature ranges to ensure functional parity. Consult official cross-reference lists for approved alternative part numbers from IQD or compatible manufacturers.
