Crystals Procurement Notes

This component is officially discontinued and no longer manufactured by Epson Timing. Procurement must rely on existing stock from authorized distributors or third-party suppliers. Verify part authenticity and storage conditions carefully due to end-of-life status. Check for valid substitute models if new production runs are required.

Crystals Selection Notes

Designers should consider alternative active crystals or modern passive equivalents due to the obsolescence of this part. Evaluate available substitutes based on matching load capacitance, frequency stability, and physical footprint requirements. Ensure replacement components meet the same environmental temperature specifications for reliable operation.

Crystals Part Context

The FC-255 series represents Epson's line of miniature surface-mount crystals. This specific model is part of a broader family that includes various load capacitance options. The series was widely used in consumer electronics before being phased out in favor of newer packaging technologies and updated product lines.
