E-TA2012 T 7DB N7 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 7DB N7 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 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 7DB N7 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 7dB (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 (exact match required)

All three substitute parts from Susumu meet these criteria and are classified as parametric equivalents. The substitutes differ only in internal construction variants (indicated by the N1, N2, and N3 designations) while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series substitutes (PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, PXV1220S-7DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 7DB N7. Selection among these three variants should be based on availability and supply chain requirements, as they are electrically and mechanically identical.

The Susumu parts carry active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. All three are supplied in Tape & Reel packaging format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Susumu PxV series parts be used as direct drop-in replacements for the E-TA2012 T 7DB N7?

A: Yes. All three Susumu substitutes meet identical electrical specifications (7dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 63mW power rating) and are packaged in the same 0805 (2012 Metric) form factor, enabling direct substitution in PCB layouts and assembly processes.

Q: What is the difference between PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, and PXV1220S-7DBN3-T02?

A: These three parts are parametric equivalents with identical electrical and mechanical specifications. The N1, N2, and N3 designations indicate internal construction variants. Selection among them should be based on inventory availability and supply chain logistics, as they are functionally interchangeable.

Q: Are the Susumu substitutes RoHS compliant?

A: Yes. All three Susumu PxV series parts are ROHS3 compliant and carry REACH Unaffected status, meeting current environmental and regulatory requirements.

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

A: The Susumu substitutes are supplied in Tape & Reel (TR) packaging, which is standard for automated surface-mount assembly operations.

Q: Why is the original E-TA2012 T 7DB N7 marked as obsolete?

A: The E-TA2012 T 7DB N7 has been discontinued by Nidec Components Corporation. The active Susumu PxV series alternatives provide equivalent performance and are recommended for new designs and ongoing production requirements.
