Procurement Notes

Verify the specific manufacturer designation, as this part number appears associated with both QST and TXC Corporation in distributor databases. Confirm the exact package dimensions and electrical parameters against the official datasheet prior to integration. Ensure the selected variant matches the required load capacitance and ESR specifications for the target circuit design to maintain frequency accuracy.

Selection Notes

Select this component when a 12 MHz fundamental mode crystal is required in a small form factor. The ±30 ppm tolerance suits general-purpose digital logic and communication interfaces. Consider the 18 pF load capacitance requirement for oscillator circuit design. The -40°C to +85°C range allows use in standard industrial and commercial equipment without additional thermal management.

Part Context

This component belongs to the QT532G series of surface-mount crystals from QST. The series offers various frequencies within the same 5.0x3.2mm footprint, allowing designers to standardize PCB layouts across different product variants. The 'HJ' suffix typically denotes specific packaging or termination characteristics within the manufacturer's lineup.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 445I23D12M00000 and 445I33D12M00000 from CTS-Frequency Controls. These alternatives share similar 12 MHz frequency, 18 pF load capacitance, and ±30 ppm stability. Verify mechanical compatibility and oscillator circuit tuning before substitution.
