Crystals Procurement Notes

This specific part number is classified as obsolete and has been discontinued by the manufacturer. Availability is limited to existing stock or secondary market sources. Verify end-of-life notifications and confirm compatibility with alternative components before finalizing procurement plans due to supply chain constraints.

Crystals Selection Notes

Select this component when a fundamental mode crystal with 18 pF load capacitance is required for through-hole assembly. Ensure the application circuit supports the specified 100 uW drive level and 80 Ohm ESR. Confirm that the operating environment remains within the -20°C to +70°C range to maintain the stated ±30 ppm frequency stability.

Crystals Part Context

The CA-301 series represents a line of standard through-hole quartz crystals from Epson Timing. This specific variant provides a 28 MHz output in a cylindrical package suitable for legacy or high-reliability designs requiring radial lead mounting. The series offers consistent performance characteristics across various frequency options within the same physical form factor.

Crystals Replacement Considerations

As the part is obsolete, verify cross-reference data sheets for direct pin-compatible substitutes. Consider modern equivalents from other manufacturers offering similar 28 MHz fundamental specifications, 18 pF load capacitance, and through-hole cylindrical packages to ensure functional parity.
