E-TA2012 T 4DB N5 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 4DB N5 is a 4dB 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 4DB N5 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 4dB (exact match required)
• Frequency Range: 0 Hz ~ 3 GHz (full coverage required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 63mW (minimum requirement)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

All three substitute parts from Susumu meet these criteria and are classified as parametric equivalents. These parts are manufactured by Susumu under the PxV series and maintain active product status, ensuring ongoing availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series parts (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 4DB N5. Selection among these three variants should be based on inventory availability and supply chain logistics:

• PXV1220S-4DBN2-T02: 1243 pcs in stock (highest availability)
• PXV1220S-4DBN1-T02: 917 pcs in stock
• PXV1220S-4DBN3-T02: 831 pcs in stock

All three parts carry active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory compliance and long-term supply continuity. The Tape & Reel packaging format is standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02 be used interchangeably with E-TA2012 T 4DB N5?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical specifications: 4dB attenuation, 0 Hz to 3 GHz frequency range, 50 ohm impedance, and 63mW power rating. Physical compatibility is confirmed through identical 0805 (2012 Metric) packaging.

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

A: The three PXV1220S variants (N1, N2, N3) are electrically and mechanically identical. Designations reflect internal manufacturing or date code variations. Selection should be based on inventory availability and procurement lead times.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: No. All parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The Susumu parts carry additional REACH unaffected certification.

Q: Is the Tape & Reel packaging compatible with existing assembly processes?

A: Tape & Reel (TR) is the standard packaging format for automated surface-mount assembly. Compatibility depends on your specific pick-and-place equipment specifications. Verify reel dimensions and tape specifications with your assembly partner if transitioning from alternative packaging formats.

Q: Why is the original E-TA2012 T 4DB N5 classified as obsolete?

A: Obsolescence typically results from manufacturer discontinuation decisions. Active Susumu equivalents ensure design continuity without performance or reliability compromise.
