Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by strict equivalence across electrical and mechanical parameters. The following criteria must be met for a part to serve as a direct substitute for the E-TA2012 2DB N2:

• 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 PXV1220S-2DBN2-T02 manufactured by Susumu meets all substitution criteria and is classified as an active product with current manufacturing support.

Engineering Selection Recommendations

The PXV1220S-2DBN2-T02 is the qualified substitute for the E-TA2012 2DB N2. Selection is based on the following factors:

• All electrical parameters (attenuation, frequency range, impedance, power rating) are identical
• Package and form factor are identical, enabling direct board-level replacement
• The substitute part maintains active product status with current manufacturing support, ensuring long-term availability
• RoHS3 compliance and REACH unaffected status provide regulatory alignment for modern supply chain requirements
• Both parts share identical ECCN and HTSUS classifications, maintaining export and tariff consistency

Frequently Asked Questions (FAQ)

Q: Can the PXV1220S-2DBN2-T02 be used as a direct replacement for the E-TA2012 2DB N2?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: 2dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 63mW power rating, and 0805 (2012 Metric) package. Pin-for-pin and footprint compatibility is maintained.

Q: What is the primary advantage of switching to the PXV1220S-2DBN2-T02?

A: The substitute part is classified as active with current manufacturing support, whereas the original E-TA2012 2DB N2 is obsolete. This ensures reliable procurement and long-term component availability for production and field service applications.

Q: Are there packaging differences between these parts?

A: The E-TA2012 2DB N2 packaging specification is not detailed in available data. The PXV1220S-2DBN2-T02 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your specific procurement and assembly process.

Q: Do regulatory certifications differ between the two parts?

A: The PXV1220S-2DBN2-T02 carries explicit RoHS3 compliance and REACH unaffected status. The original part's regulatory status is not specified. Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0020) classifications.

Q: Are there any frequency or impedance limitations when substituting?

A: No. Both parts operate identically across the full 0 Hz ~ 3 GHz frequency range at 50 Ohm impedance. No frequency-dependent or impedance-dependent limitations apply to this substitution.
