E-TA2012 T 2DB N1 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 2DB N1 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 functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 T 2DB N1 is determined by strict equivalence across the following parameters: attenuation value (2dB), frequency range (0 Hz ~ 3 GHz), impedance (50 ohms), power rating (63mW), and physical package (0805 metric). All identified substitute parts from Susumu meet these electrical and mechanical specifications without deviation. The substitutes are grouped as direct and parametric equivalents based on their identical performance characteristics and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu substitute parts (PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02) are functionally equivalent to the E-TA2012 T 2DB N1 across all specified electrical and mechanical parameters. The primary advantage of these substitutes is their active product status, ensuring long-term availability and supply chain continuity. All substitutes maintain ROHS3 compliance and identical moisture sensitivity ratings. The Susumu parts are supplied in Tape & Reel format, which is standard for automated assembly processes. Selection among the three Susumu variants should be based on inventory availability and procurement lead times, as they are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02 be used interchangeably with E-TA2012 T 2DB N1?

A: Yes. All three Susumu parts meet identical specifications for attenuation (2dB), frequency range (0 Hz ~ 3 GHz), impedance (50 ohms), power rating (63mW), and package type (0805 metric). They are direct functional equivalents.

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 manufacturing lot codes or internal design revisions that do not affect electrical or mechanical performance.

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

A: The Susumu substitutes are supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original E-TA2012 T 2DB N1 packaging format was not specified in the reference data.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's compliance profile.

Q: Why is the original E-TA2012 T 2DB N1 marked as obsolete?

A: Obsolescence indicates the part is no longer manufactured by Nidec Components Corporation. The active Susumu equivalents provide continuity for designs currently using the E-TA2012 T 2DB N1.
