E-TA2012 T 4DB N2 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 4DB N2 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 equivalent and substitute components essential for ongoing design support, production continuity, and system maintenance.

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 4DB N2 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 4dB (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 (maintained)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained)

All substitute parts listed below meet these electrical and mechanical specifications without deviation. The Susumu PxV series components PXV1220S-4DBN2-T02, PXV1220S-4DBN1-T02, and PXV1220S-4DBN3-T02 are direct parametric equivalents to the E-TA2012 T 4DB N2.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series RF attenuators (PXV1220S-4DBN2-T02, PXV1220S-4DBN1-T02, and PXV1220S-4DBN3-T02) are direct substitutes for the obsolete E-TA2012 T 4DB N2. All substitute parts maintain active product status, ensuring long-term availability and supply chain stability. Each substitute part carries ROHS3 compliance and identical electrical specifications, making them suitable for direct replacement in existing designs without circuit modification.

The availability of multiple active substitute sources from Susumu provides design flexibility and supply redundancy. Selection among the three Susumu variants may be based on procurement lead times, inventory levels, or packaging preferences, as all three components are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-4DBN2-T02, PXV1220S-4DBN1-T02, and PXV1220S-4DBN3-T02 be used interchangeably with E-TA2012 T 4DB N2?

A: Yes. All three Susumu components 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 direct substitutes requiring no circuit redesign.

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

A: The three Susumu parts (PXV1220S-4DBN2-T02, PXV1220S-4DBN1-T02, PXV1220S-4DBN3-T02) are electrically and mechanically identical. Differences, if any, relate to internal manufacturing variants or date codes and do not affect functional 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 E-TA2012 T 4DB N2 packaging specification was not provided in the reference data. Verify packaging requirements for your procurement process.

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

A: Yes. All substitute parts are ROHS3 compliant, carry the same ECCN (EAR99) and HTSUS (8533.21.0020) classifications, and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original component's regulatory profile.

Q: Why is the original E-TA2012 T 4DB N2 marked as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The active Susumi PxV series components provide equivalent functionality and ensure continued design support and production capability.
