Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's current datasheet before procurement. Confirm that the 4-SMD no-lead footprint matches the target PCB land pattern dimensions precisely. Ensure the drive level specification aligns with the host circuit's output capabilities to prevent frequency instability or crystal damage during operation.

Selection Notes

Select this component when a 26 MHz surface-mount solution is required with moderate stability needs. The 10 pF load capacitance must match the external circuit requirements to ensure accurate frequency tuning. Consider the 100 Ohm ESR value for impedance matching in the oscillator design. Verify that the operating temperature range meets the environmental constraints of the final application.

Part Context

This part belongs to the IQXC-42 series of quartz crystals from IQD Frequency Products. The series provides various frequencies and packages for general-purpose timing applications. The LFXTAL059591 specifically addresses the need for compact, reliable oscillators in space-constrained electronic designs requiring precise 26 MHz timing signals.

Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 10 pF load capacitance, and 4-SMD no-lead package dimensions. Verify equivalent ESR and drive level specifications to maintain circuit stability. Cross-reference pinout compatibility if alternative manufacturers offer similar form factors.
