Crystals Procurement Notes

Verify the specific suffix 'MT' if tape and reel packaging is required, as standard listings may indicate bulk or cut tape. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation. Ensure the 18 pF load capacitance matches the target circuit design requirements before procurement.

Crystals Selection Notes

Select this component when a 25 MHz frequency with ±10 ppm stability is required in a surface-mount form factor. Compare against variants like the FB174 or FD174 if tighter tolerances such as ±30 ppm or ±20 ppm are acceptable for the application. Verify that the HC-49/US style footprint compatibility aligns with the PCB layout constraints.

Crystals Part Context

This part is part of the SXTHM2 series from Suntsu Electronics, Inc., which offers various frequency options including 16 MHz, 24.576 MHz, and 27 MHz. The FA174 suffix typically denotes the specific package and tolerance configuration within this product line, distinguishing it from other series members with different electrical characteristics.

Crystals Replacement Considerations

Direct substitutes include the SXTHM218FB174-25.000M (±30 ppm) and SXTHM218FD174-25.000M (±20 ppm). These alternatives share the same frequency and package but offer different tolerance levels. Ensure the system timing budget allows for the looser tolerances of these variants.
