Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 7DB N3 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: Must be exactly 7dB
• Frequency Range: Must cover 0 Hz ~ 3 GHz minimum
• Impedance: Must be 50 Ohms
• Power Rating: Must be rated for 63mW or higher
• Package / Case: Must be 0805 (2012 Metric)
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The substitute part PXV1220S-7DBN3-T02 (Susumu) meets all these criteria and is classified as an active product, providing a direct functional and mechanical replacement for the obsolete E-TA2012 7DB N3.

Parameter Comparison

Engineering Selection Recommendations

The PXV1220S-7DBN3-T02 (Susumu) is the qualified substitute for the obsolete E-TA2012 7DB N3. This recommendation is based on:
