E-TA2012 T 6DB N4 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 6DB N4 is a 6dB 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 6DB N4 is determined by strict equivalence across the following electrical and mechanical parameters:

• Attenuation Value: Must be 6dB
• Frequency Range: Must cover 0 Hz ~ 3 GHz minimum
• Impedance: Must be 50 Ohms
• Power Rating: Must be 63mW or greater
• Package / Case: Must be 0805 (2012 Metric)
• RoHS Compliance: Must maintain ROHS3 Compliant status

All three substitute parts listed below meet these criteria and are manufactured by Susumu under the PxV series. These parts are currently in active production status, providing long-term availability compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series substitutes are parametrically equivalent to the E-TA2012 T 6DB N4 and are suitable for direct replacement. The primary advantage of these alternatives is their active production status, ensuring continued availability and supply chain stability.

Selection among the three substitute options (PXV1220S-6DBN1-T02, PXV1220S-6DBN2-T02, PXV1220S-6DBN3-T02) can be based on inventory availability and procurement lead times, as all three maintain identical electrical and mechanical specifications. Current inventory levels are: PXV1220S-6DBN1-T02 (619 pcs), PXV1220S-6DBN2-T02 (895 pcs), and PXV1220S-6DBN3-T02 (1124 pcs).

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can the Susumu PxV series parts be used as direct replacements for the Nidec E-TA2012 T 6DB N4?

A: Yes. All three Susumu substitute parts are parametrically equivalent across attenuation value, frequency range, impedance, power rating, package type, and compliance certifications. Direct substitution is supported without circuit modification.

Q: What is the difference between PXV1220S-6DBN1-T02, PXV1220S-6DBN2-T02, and PXV1220S-6DBN3-T02?

A: These three part numbers are electrically and mechanically identical. The suffix variation (N1, N2, N3) represents different manufacturing batches or internal designations by Susumu. All three meet the same electrical specifications and are suitable for the same applications.

Q: Are the substitute parts available in the same packaging format?

A: The Susumu substitutes are supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface-mount component distribution. This packaging format is compatible with automated assembly equipment used for 0805 (2012 metric) components.

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

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original E-TA2012 T 6DB N4.

Q: Why is the original part listed as obsolete?

A: The E-TA2012 T 6DB N4 has been discontinued by Nidec Components Corporation. The active Susumu alternatives provide equivalent functionality and ensure continued design support and component availability.
