E-TA2012 T 4DB N8 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 4DB N8 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 components essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 4DB N8 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 components are currently in active production status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series components (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 4DB N8. All substitute parts maintain identical electrical specifications and physical form factor, with the primary distinction being active production status and REACH compliance certification.

Selection among the three Susumu variants should be based on inventory availability and supply chain requirements. Current stock levels are: PXV1220S-4DBN2-T02 (1243 pcs), PXV1220S-4DBN1-T02 (917 pcs), and PXV1220S-4DBN3-T02 (831 pcs).

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, or PXV1220S-4DBN3-T02 be used as direct replacements for E-TA2012 T 4DB N8?

A: Yes. All three Susumu components are parametric equivalents with identical attenuation value (4dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 Metric). They are suitable for direct substitution in existing designs.

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

A: The three PXV1220S variants (N1, N2, N3 designations) are parametrically identical. The suffix designations reflect internal manufacturing or specification tracking codes. All three meet the same electrical and mechanical requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Susumu substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the packaging format for the substitute parts?

A: The Susumu substitute parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The physical package remains 0805 (2012 Metric), identical to the original component.

Q: Why is the original E-TA2012 T 4DB N8 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production by Nidec Components Corporation. The identified Susumu equivalents provide continuity for applications requiring 4dB RF attenuation in the 0 Hz to 3 GHz range.
