Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 2DB N3 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: Must be 2dB
• Frequency Range: Must cover 0 Hz ~ 3 GHz minimum
• Impedance: Must be 50 Ohms
• Power Rating: Must be 63mW or greater
• Package / Case: Must be 0805 (2012 Metric)
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The substitute part PXV1220S-2DBN3-T02 from Susumu meets all these electrical and mechanical requirements, making it a direct functional equivalent for the obsolete E-TA2012 2DB N3.
