Crystals Procurement Notes

Verify the specific part number against official Suntsu Electronics documentation to confirm electrical parameters such as frequency tolerance and load capacitance. Ensure the procurement source provides valid datasheets matching the SXT21420BB38-37.400M designation. Cross-reference package dimensions and RoHS compliance status with manufacturer specifications before integration into production designs.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with 20 pF load capacitance. Consider the 100 Ohm ESR and ±30 ppm stability limits for circuit compatibility. The 4-SMD no-lead package dictates PCB layout constraints. Verify operating temperature ranges and mounting requirements against system specifications to ensure reliable performance under environmental conditions.

Crystals Part Context

This component belongs to the SXT214 series of quartz crystals from Suntsu Electronics. The series offers various frequencies within the same physical footprint, allowing for design flexibility. The SXT21420BB38 variant specifically denotes the 37.4 MHz frequency option with standard packaging and electrical characteristics defined for surface-mount technology implementations.

Crystals Replacement Considerations

Direct substitutes include other SXT214 series parts with identical package dimensions but different frequencies, such as SXT21420BB38-24.000M or SXT21420BB38-50.000M, provided the circuit oscillator can accommodate the new frequency. Verify that alternative manufacturers' components match the 20 pF load capacitance and 100 Ohm ESR requirements.
