E-TA2012 T 2DB N7 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 2DB N7 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.

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 T 2DB N7 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 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 obsolete Nidec component.

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 obsolete E-TA2012 T 2DB N7. Selection among these three active alternatives should be based on availability and supply chain requirements:

• PXV1220S-2DBN1-T02: 874 pcs in stock
• PXV1220S-2DBN2-T02: 868 pcs in stock
• PXV1220S-2DBN3-T02: 740 pcs in stock

All three parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current production environments. The Tape & Reel packaging format ensures compatibility with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can any of the Susumu PxV series parts be used interchangeably with the E-TA2012 T 2DB N7?

A: Yes. PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02 are parametric equivalents with identical electrical specifications (2dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 ohms impedance, 63mW power rating) and mechanical compatibility (0805 package). All three are direct substitutes.

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

A: The three Susumu parts are parametrically identical across all electrical and mechanical specifications. Differences are limited to inventory availability and internal part numbering variants within the PxV series.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Susumu substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: Is the 0805 package compatible with existing PCB designs for the E-TA2012?

A: Yes. All substitute parts use the 0805 (2012 metric) package, providing direct mechanical and footprint compatibility with existing designs.

Q: What is the moisture sensitivity level for the substitute parts?

A: All substitute parts have a Moisture Sensitivity Level of 1 (Unlimited), matching the original E-TA2012 T 2DB N7 specification.
