Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required pinout and electrical specifications. Confirm that the 4-SMD package dimensions align with your PCB footprint requirements. Check for any recent updates to the RoHS compliance status or material declarations before finalizing procurement orders.

Selection Notes

Select this component when a stable 27 MHz reference is required for HCMOS-compatible digital circuits. Ensure the design supports a 3.3V supply rail. Consider the thermal characteristics of ceramic oscillators relative to crystal alternatives if high stability across extreme temperature ranges is critical for the application environment.

Part Context

This part belongs to the family of standard ceramic oscillators manufactured by Geyer Electronic America, Inc. These devices are designed to replace discrete crystal and capacitor networks, offering a simplified solution for clock generation in consumer electronics and industrial control systems requiring precise timing signals.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that alternative components match the 27 MHz frequency, 3.3V operation, and HCMOS output type. Ensure physical package compatibility for the 4-SMD form factor.
