Crystals Procurement Notes

This component is officially discontinued and no longer manufactured. Verify availability through authorized distributors for remaining stock or consider the listed replacement models. Ensure compliance with RoHS3 standards and confirm end-of-life notifications prior to final design implementation.

Crystals Selection Notes

Select this part for applications requiring a 24.576 MHz reference in compact form factors. Note that it operates in third overtone mode, which may require specific circuit tuning compared to fundamental mode crystals. Confirm that the -20°C to +70°C operating range meets environmental requirements.

Crystals Part Context

Part of the 7B series, designed for small-volume wireless devices. Offers improved EMI performance over standard HC-49S packages. Provides reliable timing for Bluetooth and NFC interfaces where size and signal integrity are critical constraints.

Crystals Replacement Considerations

Public confirmed substitute: 7M-50.000MAAJ-T (Note: Frequency mismatch requires verification). Alternative family members like 7V-24.576MAAE-T offer similar frequencies but differ in package size and load capacitance.
