E-TA2012 T 2DB N4 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 2DB N4 is a 2dB 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 eligibility for the E-TA2012 T 2DB N4 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 2dB (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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria and are manufactured by Susumu under the PxV series designation. These parts are currently in active production status, providing long-term availability for design continuity.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series alternatives (PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, PXV1220S-2DBN3-T02) are direct parametric equivalents to the E-TA2012 T 2DB N4. Selection among these alternatives should be based on inventory availability and supply chain logistics, as all three parts are manufactured by Susumu and maintain active production status.

The transition from the obsolete Nidec component to any of the Susumu alternatives presents no electrical or mechanical compatibility concerns. All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Packaging remains identical at 0805 (2012 metric), ensuring direct board-level compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02 be used interchangeably with E-TA2012 T 2DB N4?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical specifications (2dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 ohms impedance, 63mW power rating) and mechanical requirements (0805 package). They are electrically and mechanically interchangeable.

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

A: The three Susumu parts (PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, PXV1220S-2DBN3-T02) are parametrically identical. Differences, if any, relate to internal manufacturing variants or tape reel configurations not specified in the provided data. Selection should be based on supplier availability.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: No. Both the original E-TA2012 T 2DB N4 and all Susumu substitutes are ROHS3 compliant. The Susumu parts additionally carry REACH unaffected status. All parts share identical ECCN (EAR99) and HTSUS (8533.21.0020) classifications.

Q: Will substituting these parts require PCB redesign?

A: No. The 0805 (2012 metric) package specification is identical across all parts. Direct board-level substitution is possible without layout modifications.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.
