Crystals Procurement Notes

Verify the specific ESR value and drive level requirements against your circuit design before procurement, as these parameters are critical for oscillator stability. Confirm that the 10pF load capacitance matches the oscillator circuit's input capacitance calculations. Ensure the PCB footprint aligns with the 2.00mm x 1.60mm package dimensions. Check for any specific handling instructions regarding moisture sensitivity despite the MSL Level 1 rating.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with ±10 ppm stability. Compare against other 402 series variants if different load capacitances or temperature ranges are needed. Ensure the application does not exceed the maximum drive level specified in the official datasheet to prevent frequency drift or crystal damage. Consider the physical size constraints of the target PCB layout relative to the 4-SMD package.

Crystals Part Context

This part belongs to the CTS 402 Series, a line of surface-mount crystals covering frequencies from 16 MHz to 60 MHz. The series is known for providing reliable frequency control solutions for consumer, industrial, and telecommunications equipment. The 402F37412IAR specifically targets the 37.4 MHz niche within this broader portfolio, offering standardized packaging for easy integration into existing designs.

Crystals Replacement Considerations

Direct substitutes may include other 37.4 MHz SMD crystals with identical 10pF load capacitance and ±10 ppm stability. Verify mechanical compatibility with the 4-SMD 2x1.6mm footprint. Cross-reference with other manufacturers' equivalent parts only if electrical parameters match exactly. Note that lead times and availability vary significantly across suppliers; check current stock status carefully.
