E-TA2012 T 4DB N7 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 4DB N7 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 alternatives essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 4DB N7 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 parts are currently in active production status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series parts (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, PXV1220S-4DBN3-T02) are direct parametric equivalents to the E-TA2012 T 4DB N7. Selection among these three active alternatives should be based on:

• Availability: Current inventory levels are 917 pcs (PXV1220S-4DBN1-T02), 1243 pcs (PXV1220S-4DBN2-T02), and 831 pcs (PXV1220S-4DBN3-T02)
• Compliance: All parts maintain ROHS3 compliance and REACH unaffected status
• Supply Chain Continuity: Active production status ensures sustained availability compared to the obsolete original part

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02 be used interchangeably with E-TA2012 T 4DB N7?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical specifications: 4dB attenuation, 0 Hz to 3 GHz frequency range, 50 ohm impedance, and 63mW power rating. Physical compatibility is confirmed through identical 0805 (2012 metric) packaging.

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

A: The three PxV series parts (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, PXV1220S-4DBN3-T02) are parametric equivalents with identical electrical and mechanical specifications. Differences are limited to internal manufacturing variants or tolerance grades not specified in the provided parameters.

Q: Why is the original E-TA2012 T 4DB N7 marked as obsolete?

A: Obsolescence indicates the part is no longer in active production. The Susumu PxV series alternatives provide equivalent functionality with the advantage of active production status and assured long-term availability.

Q: Are all substitute parts RoHS compliant?

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

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

A: All three Susumu alternatives are supplied in Tape & Reel (TR) format, standard for high-volume surface-mount assembly operations.
