Procurement Notes

Verify the specific package variant and tolerance requirements against the official datasheet before procurement. Confirm that the 4-SMD footprint matches the target PCB layout. Ensure compatibility with reflow soldering profiles specified for this component type. Cross-reference the manufacturer's latest documentation to confirm current availability status and any potential obsolescence notices.

Selection Notes

Select this component when a 26 MHz fundamental crystal with tight ±10 ppm stability is required in a small SMD footprint. The 12 pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR value for drive level sensitivity. Verify that the operating temperature range meets the application environment specifications.

Part Context

This crystal belongs to the IQXC-42 series from IQD Frequency Products, which specializes in miniature surface-mount quartz components. The series targets applications demanding high reliability and small board space. As a fundamental mode device, it provides stable oscillation without harmonic multiplication, suitable for direct integration into standard oscillator circuits.

Replacement Considerations

Substitutes must match the 26 MHz frequency, ±10 ppm stability, 12 pF load capacitance, and 4-SMD package dimensions. Verify equivalent ESR values and fundamental mode operation. Check for compatible mounting pads and thermal characteristics.
