E-TA2012 T 3DB N1 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 3DB N1 is a 3dB 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 listed as obsolete, making identification of equivalent substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 T 3DB N1 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 3dB (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)

All substitute parts listed below meet these electrical and mechanical specifications without deviation. The Susumu PxV series components PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02 are parametric equivalents that satisfy all required performance criteria.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series attenuators (PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, PXV1220S-3DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 3DB N1. All substitute parts maintain active product status, ensuring long-term availability and supply chain stability. Each substitute meets ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements equivalent to the original component.

Selection among the three Susumu variants should be based on inventory availability and procurement lead times. Current stock levels are: PXV1220S-3DBN1-T02 (973 Pcs), PXV1220S-3DBN2-T02 (740 Pcs), and PXV1220S-3DBN3-T02 (1354 Pcs). All three parts are supplied in Tape & Reel packaging format suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Susumu PxV series parts directly replace the E-TA2012 T 3DB N1 without circuit modification?

A: Yes. The Susumu parts are parametric equivalents meeting identical electrical specifications (3dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 63mW power rating) and mechanical specifications (0805 package). No circuit redesign is required.

Q: What is the difference between PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02?

A: All three parts are parametrically identical. The suffix variation (N1, N2, N3) represents different manufacturing batches or internal designations within Susumu's product line. Electrical and mechanical performance is equivalent across all three variants.

Q: Are the substitute parts available in packaging formats other than Tape & Reel?

A: The provided data specifies Tape & Reel (TR) packaging for all Susumu substitute parts. Alternative packaging formats are not documented in the available specifications.

Q: Do the substitute parts meet the same compliance standards as the original E-TA2012 T 3DB N1?

A: Yes. All Susumu substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original component. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts.

Q: Why is the original E-TA2012 T 3DB N1 listed as obsolete?

A: Obsolescence status indicates the part is no longer in active production by Nidec Components Corporation. The Susumu PxV series alternatives provide equivalent functionality with active product status and ongoing manufacturer support.
