Procurement Notes
Verify the specific suffix 'D' in the part number against official QST documentation to confirm the exact supply voltage and output configuration. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout. Cross-reference the datasheet for any updates on RoHS compliance status.
Selection Notes
Select this component when a 27 MHz clock source is required with strict size constraints due to its 2016 footprint. Consider the 1.8V supply requirement and 5mA current draw for battery-powered designs. Verify that the ±50ppm total stability meets the system timing requirements without additional compensation.
Part Context
This model belongs to the QTM216 series of surface-mount oscillators from QST. The series offers various frequencies and supply voltages within a standardized 2.0x1.6mm package. The 'D' suffix typically indicates specific electrical characteristics such as supply voltage and enable functions distinct from other variants like 'B'.
Replacement Considerations
Direct substitutes may include other QTM216 variants with matching 27 MHz frequency and compatible supply voltage. Check pinout compatibility and package dimensions before replacing. Consult QST documentation for equivalent parts with different stability or temperature ratings.
