E-TA2012 T 5DB N4 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 5DB N4 is a 5dB 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 5DB N4 is determined by strict equivalence across the following critical parameters: attenuation value (5dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 2012 Metric). All identified substitute parts from Susumu meet these electrical and mechanical specifications without deviation. The substitutes are grouped as parametric equivalents because they maintain identical performance characteristics across all specified operating conditions. Packaging format (Tape & Reel) and active product status of the substitute parts provide additional advantages for procurement and long-term availability.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu substitute parts (PXV1220S-5DBN1-T02, PXV1220S-5DBN2-T02, PXV1220S-5DBN3-T02) are direct parametric equivalents to the E-TA2012 T 5DB N4. Selection among these substitutes should be based on inventory availability and procurement lead times. All substitutes carry active product status, ensuring long-term supply chain stability compared to the obsolete original part. All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current manufacturing standards. The Tape & Reel packaging format of the substitutes supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-5DBN1-T02, PXV1220S-5DBN2-T02, and PXV1220S-5DBN3-T02 be used interchangeably with E-TA2012 T 5DB N4?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical specifications (5dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 ohms impedance, 63mW power rating) and mechanical specifications (0805 2012 Metric package). They are functionally interchangeable in circuit applications.

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

A: The three Susumu parts (PXV1220S-5DBN1-T02, PXV1220S-5DBN2-T02, PXV1220S-5DBN3-T02) are parametrically identical. Differences exist only in internal design variants or manufacturing batches, not in electrical or mechanical performance. Selection should be based on inventory availability.

Q: Are the substitute parts compatible with existing PCB layouts designed for E-TA2012 T 5DB N4?

A: Yes. Both the original part and all substitutes use the 0805 (2012 Metric) package, ensuring identical footprint compatibility and PCB layout reuse without modification.

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

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original part. Both the original and substitutes carry EAR99 ECCN classification and 8533.21.0020 HTSUS code.

Q: Why is the original E-TA2012 T 5DB N4 marked as obsolete?

A: Obsolescence indicates the part is no longer in active production by the manufacturer. The identified Susumu substitutes are active products, providing continuity for designs requiring 5dB RF attenuation in the 0 Hz ~ 3 GHz range.
