Procurement Notes

This component has been officially announced as End-of-Life (EOL) by TDK Corporation, with the announcement dated June 3, 2022. Production ceased on March 31, 2023, and final shipments concluded by March 31, 2024. It is classified as Not Recommended for New Designs (NRND). Verification of current availability should focus on obsolete stock or authorized distributors holding remaining inventory, as new manufacturing is discontinued.

Selection Notes

Designers should consider this part only for maintenance or legacy system repairs due to its EOL status. For new designs, alternative components from the same family or compatible RF filters must be selected. Ensure that any substitute maintains the required 50 Ohm impedance and fits the physical footprint constraints of the original layout.

Part Context

The DEA162450BT series comprises LTCC bandpass filters intended for wireless communication modules. This specific model targets the 2.4/2.5 GHz ISM bands commonly used in Wi-Fi and Bluetooth technologies. The product line emphasizes high performance in a small form factor, aligning with trends in miniaturized electronic devices.

Replacement Considerations

TDK recommends checking for available substitutes listed in their official documentation. Verify electrical compatibility including center frequency, bandwidth, and insertion loss before integrating any replacement component into the circuit design.
