Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 3DB N2 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: Must be 3dB
• 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-3DBN2-T02 manufactured by Susumu meets all these criteria and is classified as a direct equivalent. This part maintains identical electrical specifications and mechanical form factor, enabling pin-for-pin and functional replacement in existing designs.

Engineering Selection Recommendations

The PXV1220S-3DBN2-T02 is the qualified substitute for the E-TA2012 3DB N2. Selection of this alternative is supported by:

• Electrical Equivalence: Identical attenuation, frequency range, impedance, and power specifications
• Mechanical Compatibility: Same 0805 (2012 Metric) package enables direct PCB placement without layout modification
• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain stability
• Compliance Certifications: ROHS3 compliance and REACH unaffected status meet current regulatory requirements
• Moisture Handling: Equivalent MSL 1 rating ensures identical moisture sensitivity characteristics

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-3DBN2-T02 be used as a direct replacement for E-TA2012 3DB N2?

A: Yes. Both parts share identical electrical specifications (3dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohms impedance, 63mW power rating) and the same 0805 (2012 Metric) package form factor. The substitute is pin-for-pin compatible and functionally equivalent.

Q: What is the primary advantage of switching to PXV1220S-3DBN2-T02?

A: The substitute part is in active production status, whereas the original E-TA2012 3DB N2 is obsolete. This ensures reliable long-term availability and supply chain continuity for new production runs or system maintenance.

Q: Are there any compliance differences between the two parts?

A: The substitute PXV1220S-3DBN2-T02 carries ROHS3 compliance and REACH unaffected certification. These certifications meet current environmental and regulatory standards for electronic components in most markets.

Q: Does the packaging format differ between these parts?

A: Both parts are supplied in 0805 (2012 Metric) surface-mount packages. The substitute is available in Tape & Reel (TR) packaging format, which is standard for automated assembly processes.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity characteristics and storage requirements.
