Procurement Notes
This component has an official obsolete status, indicating it is no longer in active production. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Ensure that any acquired units meet the original RoHS3 compliance specifications and have been stored under appropriate conditions to maintain performance integrity.
Selection Notes
Engineers replacing this part must account for its obsolete status when designing new products. Selection criteria should prioritize components with identical 2.45GHz center frequency, 0805 footprint, and similar insertion loss characteristics. Verify that alternative filters support the required 100MHz bandwidth and operate within the specified -40°C to +85°C temperature range to ensure system compatibility.
Part Context
The DEA series represents TDK's line of ceramic RF filters designed for high-frequency applications. These components are engineered to provide precise frequency selection and noise rejection in compact form factors suitable for modern electronic devices. The DEA202450BT-7076C1 specifically targets the widely used 2.45GHz ISM band, serving as a critical element in maintaining signal integrity for wireless transmission modules.
Replacement Considerations
Publicly confirmed substitute part numbers are not available for this specific obsolete model. Engineers should consult TDK technical support or evaluate third-party RF filters with matching electrical parameters and physical dimensions for potential cross-referencing.
