Crystals Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official documentation to confirm the exact tolerance and packaging specifications. Ensure that the 4-SMD no-lead footprint matches the PCB layout requirements. Cross-reference the datasheet for reflow soldering profiles to prevent thermal damage during assembly. Confirm availability through authorized distributors as stock levels may fluctuate.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency with ±25 ppm stability is required for space-constrained designs. The 20 pF load capacitance must align with the host circuit's input requirements. Consider the 60 Ohm ESR for drive level sensitivity. The industrial temperature range makes it suitable for environments exceeding standard commercial limits without compromising frequency accuracy.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT21420 series of surface-mount crystals. The series offers various frequencies and packages, with the CB48 suffix indicating the specific case size and pin configuration. It is designed for general-purpose timing applications where moderate stability and low cost are prioritized over high-precision requirements found in other series.

Crystals Replacement Considerations

Direct substitutes include the SXT21420CC07-50.000MT and SXT21420BB48-50.000M, provided they meet the same electrical parameters. Verify that any replacement maintains the 4-SMD no-lead footprint and 20 pF load capacitance. Check if alternative parts offer improved temperature stability or lower ESR if the application demands higher performance than the original specification.
