Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 1DB N2 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: Must be 1dB
• 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 identified substitute part meets all these criteria and is therefore electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

The PXV1220S-1DBN2-T02 from Susumu is a direct functional equivalent to the obsolete E-TA2012 1DB N2. Both components share identical electrical specifications (1dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 63mW power rating) and mechanical packaging (0805 2012 Metric).

The Susumu part offers the advantage of active product status, ensuring ongoing availability and supply chain reliability. The PXV1220S-1DBN2-T02 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Both parts maintain MSL 1 moisture sensitivity classification, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the PXV1220S-1DBN2-T02 be used as a direct replacement for the E-TA2012 1DB N2?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 1dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 63mW power rating, and 0805 (2012 Metric) package. No circuit modifications are required.

Q: What is the difference in packaging between these parts?

A: The E-TA2012 1DB N2 packaging format is not specified in available documentation. The PXV1220S-1DBN2-T02 is supplied in Tape & Reel (TR) format. Both use the same 0805 (2012 Metric) surface-mount package footprint.

Q: Are there compliance differences between these parts?

A: The PXV1220S-1DBN2-T02 is ROHS3 compliant and REACH unaffected. The E-TA2012 1DB N2 compliance status is not specified. Both parts carry ECCN EAR99 and HTSUS 8533.21.0020 classifications.

Q: Why is the E-TA2012 1DB N2 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Nidec Components Corporation. The PXV1220S-1DBN2-T02 maintains active product status with current manufacturing and supply availability.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture-related storage or handling restrictions apply to either component.
