E-TA2012 T 3DB N2 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 3DB N2 is a 3dB 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 product is currently obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 3DB N2 is determined by strict equivalence across the following critical parameters: attenuation value (3dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 2012 Metric). All identified substitute parts from Susumu maintain these electrical and mechanical specifications, ensuring functional compatibility in RF signal attenuation applications. Packaging format (Tape & Reel) differs from the original but does not affect electrical performance or board-level integration.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series alternatives (PXV1220S-3DBN2-T02, PXV1220S-3DBN1-T02, PXV1220S-3DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 3DB N2. Each maintains identical electrical specifications and package dimensions. All substitute parts carry Active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. Selection among the three Susumu variants may be based on inventory availability and procurement lead times, as electrical performance is equivalent across all options.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-3DBN2-T02, PXV1220S-3DBN1-T02, and PXV1220S-3DBN3-T02 be used interchangeably with E-TA2012 T 3DB N2?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation (3dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 2012 Metric). Electrical performance and board-level compatibility are equivalent.

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

A: The three PxV series parts (PXV1220S-3DBN2-T02, PXV1220S-3DBN1-T02, PXV1220S-3DBN3-T02) are parametrically identical. Differences are limited to internal design variants or manufacturing batches. All meet the same electrical and mechanical specifications.

Q: Does the packaging format change affect compatibility?

A: The original E-TA2012 T 3DB N2 packaging format is not specified in available data. Susumu substitutes are supplied in Tape & Reel (TR) format, which is standard for 0805 surface-mount components and does not affect electrical performance or PCB assembly compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three Susumu alternatives carry ROHS3 Compliant certification, matching the compliance status of the original part.

Q: Which substitute part should I select?

A: Selection may be based on inventory availability and procurement lead times. PXV1220S-3DBN3-T02 currently has the highest inventory (1354 Pcs), followed by PXV1220S-3DBN1-T02 (973 Pcs) and PXV1220S-3DBN2-T02 (740 Pcs). Electrical performance is identical across all three options.
