E-TA2012 T 7DB N4 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 7DB N4 is a 7dB 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 7DB N4 is determined by strict equivalence across the following parameters: attenuation value (7dB), 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 identical electrical and mechanical specifications, ensuring direct functional compatibility. The substitute parts are classified as active products with current manufacturing status, providing supply continuity for the obsolete Nidec original.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu substitute parts (PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, PXV1220S-7DBN3-T02) are direct parametric equivalents to the E-TA2012 T 7DB N4. Selection among these active alternatives should be based on inventory availability and supply chain requirements. All substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. The transition from the obsolete Nidec part to any of these Susumu equivalents presents no electrical or mechanical compatibility constraints for applications operating within the specified 0 Hz to 3 GHz frequency range at 50 ohm impedance.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, and PXV1220S-7DBN3-T02 be used interchangeably with E-TA2012 T 7DB N4?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation (7dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). They are direct functional replacements.

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

A: The three Susumu parts (PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, PXV1220S-7DBN3-T02) share identical electrical and mechanical specifications. Differences, if any, relate to internal manufacturing variants or date codes and do not affect electrical performance or compatibility.

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

A: The original E-TA2012 T 7DB N4 and all substitute parts use the 0805 (2012 Metric) surface-mount package. The Susumu substitutes are supplied in Tape & Reel (TR) format, which is standard for production quantities and does not affect component functionality or PCB assembly compatibility.

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 component. Both the original and substitutes carry EAR99 ECCN classification and 8533.21.0020 HTSUS code.

Q: Why is the original E-TA2012 T 7DB N4 classified as obsolete?

A: Obsolescence indicates the part is no longer in active production by the original manufacturer. The identified Susumu equivalents provide continuity for applications requiring 7dB RF attenuation in the 0 Hz to 3 GHz range.
