Crystals Procurement Notes

Verify the specific suffix '174' against the manufacturer's official datasheet to confirm the exact pinout and mechanical dimensions. Ensure the application environment remains within the specified -10°C to +70°C operating range to maintain the stated ±30 ppm stability. Cross-reference the 18 pF load capacitance requirement with the host circuit design to prevent frequency deviation.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required in a compact surface-mount form factor. The ±30 ppm tolerance suits applications where moderate frequency accuracy is sufficient. Consider the -10°C lower temperature limit if the device will be deployed in colder environments, as alternative variants may be necessary for extended ranges.

Crystals Part Context

This part belongs to the SXTHM2 series of crystals from Suntsu Electronics. The series includes various frequencies and package types. The '174' suffix typically denotes specific mechanical or electrical characteristics within this product line, distinguishing it from other variants like the BB274 series which may share similar electrical parameters but differ in physical attributes.

Crystals Replacement Considerations

Direct substitutes include the SXTHM218BB274-40.000M, which shares identical electrical specifications including 40 MHz frequency, 18 pF load capacitance, and ±30 ppm stability. Verify mechanical compatibility before substitution, as package dimensions may vary between suffixes.
