E-TA2012 T 2DB N5 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 2DB N5 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 N5 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)

All three substitute parts listed below meet these criteria and are manufactured by Susumu in the active PxV series, providing direct functional and mechanical compatibility with the original component.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series alternatives provide direct parametric equivalence to the obsolete E-TA2012 T 2DB N5. Selection among PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02 may be based on inventory availability and supply chain considerations, as all three parts are currently active and maintain identical electrical and mechanical specifications. All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The transition from the obsolete Nidec component to any of these active Susumu alternatives ensures continued design compliance and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02 be used interchangeably with E-TA2012 T 2DB N5?

A: Yes. All three Susumu parts meet identical electrical specifications (2dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 ohms impedance, 63mW power rating) and are packaged in the same 0805 (2012 metric) form factor, providing direct functional and mechanical compatibility.

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

A: PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02 are parametrically identical. Differences are limited to inventory levels and internal manufacturing lot designations. Selection should be based on supply chain availability.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Susumu alternatives are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

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

A: All three Susumu alternatives are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Why is the original E-TA2012 T 2DB N5 listed as obsolete?

A: The E-TA2012 T 2DB N5 has been discontinued by Nidec Components Corporation. The active Susumu PxV series alternatives provide equivalent performance and are recommended for new designs and ongoing production requirements.
