Crystals Procurement Notes

Verify the specific suffix B5 against official Epson documentation to confirm packaging configuration and lead-free status. Ensure compatibility with reflow soldering profiles specified in the datasheet. Cross-reference load capacitance requirements with circuit design specifications to maintain frequency accuracy within stated tolerances.

Crystals Selection Notes

Select this component when a 48 MHz reference is required with moderate stability needs. The 16 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. The -40°C to +85°C range suits general commercial and industrial uses where extreme thermal conditions are not present.

Crystals Part Context

This part belongs to the FA-128 series of crystals by Epson, known for small form factors and reliability. The series offers various frequencies and package options. The FA-128 specifically targets applications requiring space-saving solutions without compromising timing precision, widely used in consumer electronics and embedded systems.

Crystals Replacement Considerations

Direct substitutes include other FA-128 variants with matching 48 MHz frequency, 16 pF load capacitance, and similar ESR values. Verify pinout and mechanical dimensions before substitution. Alternative manufacturers may offer comparable specs but require validation of frequency stability and temperature coefficients.
