E-TA2012 T 4DB N6 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 4DB N6 is a 4dB RF attenuator manufactured by Nidec Components Corporation, designed for applications requiring signal attenuation across the 0 Hz to 3 GHz frequency range. This component operates at 50 ohms impedance with a power rating of 63mW in a compact 0805 (2012 metric) surface-mount package. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 4DB N6 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 4dB (exact match required)
• Frequency Range: 0 Hz ~ 3 GHz (full coverage required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 63mW (minimum requirement)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

All three substitute parts from Susumu meet these criteria and are classified as parametric equivalents. These parts are manufactured by Susumu under the PxV series and maintain active product status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu substitute parts (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02) are direct parametric equivalents to the E-TA2012 T 4DB N6. Selection among these three options should be based on inventory availability and supply chain logistics, as they are electrically and mechanically identical.

The transition from the obsolete Nidec component to active Susumu alternatives ensures:

• Continued component availability through established distribution channels
• ROHS3 compliance maintained across all substitute options
• REACH unaffected status for all Susumu alternatives
• Identical electrical performance across the specified frequency range and impedance

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02 be used interchangeably with E-TA2012 T 4DB N6?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation (4dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package (0805 metric). They are electrically and mechanically interchangeable.

Q: What is the difference between the three Susumu substitute parts?

A: The three Susumu parts (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, PXV1220S-4DBN3-T02) are parametrically identical. Differences, if any, relate to manufacturing date codes or internal construction variants that do not affect electrical performance or compatibility.

Q: Are the substitute parts available in the same packaging as the original?

A: The substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for high-volume production. The original part packaging was not specified in available documentation. Both formats are compatible with automated assembly equipment.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original E-TA2012 T 4DB N6.

Q: Why is the original E-TA2012 T 4DB N6 classified as obsolete?

A: Obsolescence typically results from manufacturer discontinuation. The active Susumi alternatives ensure design continuity without performance compromise.
