Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 4DB N3 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: Must be 4dB
• 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-4DBN3-T02 manufactured by Susumu meets all these criteria and is classified as an active product, providing supply availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The PXV1220S-4DBN3-T02 is the direct equivalent substitute for the E-TA2012 4DB N3. Both components share identical electrical specifications and mechanical form factor. The Susumu part offers the advantage of active product status, ensuring continued availability and manufacturer support.

The PXV1220S-4DBN3-T02 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The component is available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the PXV1220S-4DBN3-T02 be used as a direct replacement for the E-TA2012 4DB N3?

A: Yes. Both components have identical attenuation values (4dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). No circuit modifications are required.

Q: What is the difference between the two parts?

A: The primary difference is product status. The E-TA2012 4DB N3 is obsolete, while the PXV1220S-4DBN3-T02 is active. The Susumu part also includes ROHS3 compliance and REACH unaffected certifications.

Q: Are there packaging differences between these parts?

A: The E-TA2012 4DB N3 packaging format is not specified in available data. The PXV1220S-4DBN3-T02 is supplied in Tape & Reel (TR) format. Both use the same 0805 (2012 Metric) surface-mount package footprint.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating.

Q: Are there other substitute options available?

A: The provided data identifies PXV1220S-4DBN3-T02 as the direct equivalent. The Susumu PxV series includes related variants (PXV1220S-4DBN2-T02, PXV1220S-4DBN1-T02) that differ in attenuation specifications and are not direct substitutes for the 4dB requirement.
