E-TA2012 T 3DB N5 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 3DB N5 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 Ohm 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 3DB N5 is determined by strict equivalence across the following electrical and mechanical parameters:

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

All three substitute parts from Susumu meet these criteria and are classified as active products, providing direct functional and mechanical compatibility with the obsolete Nidec component.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series alternatives (PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, PXV1220S-3DBN3-T02) provide direct substitution for the obsolete E-TA2012 T 3DB N5. Each substitute maintains identical electrical specifications and mechanical form factor while offering active product status and ROHS3 compliance. The Susumu components are supplied in Tape & Reel packaging, suitable for automated assembly processes. Selection among the three variants should be based on inventory availability and supply chain requirements, as all three are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can the Susumu PxV series parts directly replace the Nidec E-TA2012 T 3DB N5?

A: Yes. All three Susumu alternatives match the required electrical parameters (3dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 63mW power rating) and mechanical specifications (0805 package). Direct substitution is supported.

Q: What is the difference between PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02?

A: These three part numbers are parametric equivalents with identical electrical and mechanical specifications. Differences are limited to internal design variants within the Susumu PxV series. All three meet the same performance requirements for this application.

Q: Are there packaging considerations when switching from the Nidec part to Susumu alternatives?

A: The Susumu alternatives are supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. The 0805 (2012 Metric) form factor remains unchanged, ensuring compatibility with existing PCB designs and pick-and-place equipment.

Q: Do the substitute parts meet RoHS and compliance requirements?

A: Yes. All Susumu alternatives are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the original Nidec component. REACH status for the Susumu parts is listed as REACH Unaffected.
