E-TA2012 T 7DB N3 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 7DB N3 is a 7dB 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 Ohm impedance with 63mW power handling capability 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 7DB N3 is determined by strict equivalence across the following critical parameters: attenuation value (7dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). All identified substitute parts from Susumu maintain identical electrical and mechanical specifications, ensuring direct functional compatibility. The substitutes are grouped as direct manufacturer equivalents and parametric equivalents, all meeting ROHS3 compliance and MSL Level 1 requirements.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu substitute parts (PXV1220S-7DBN3-T02, PXV1220S-7DBN1-T02, and PXV1220S-7DBN2-T02) are functionally equivalent to the obsolete E-TA2012 T 7DB N3. Selection among these active alternatives should be based on availability and supply chain requirements. All substitutes maintain ROHS3 compliance, REACH unaffected status, and identical electrical performance across the specified frequency and impedance parameters. Packaging is supplied in Tape & Reel (TR) format for all Susumu alternatives.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, and PXV1220S-7DBN3-T02 be used interchangeably with E-TA2012 T 7DB N3?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation (7dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). They are direct functional replacements.

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

A: The three Susumu parts (PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, PXV1220S-7DBN3-T02) are parametric equivalents with identical electrical and mechanical specifications. Differences are limited to internal manufacturing variants and inventory availability.

Q: Are the substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

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

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

Q: Why is the original E-TA2012 T 7DB N3 listed as obsolete?

A: The E-TA2012 T 7DB N3 has been discontinued by Nidec Components Corporation. The active Susumu alternatives provide equivalent performance and are recommended for new designs and production continuity.
