E-TA2012 T 1DB N5 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 1DB N5 is a 1dB 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 components essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 1DB N5 is determined by strict equivalence across the following electrical and mechanical parameters:

• Attenuation Value: 1dB (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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All three substitute parts listed below meet these criteria and are manufactured by Susumu under the PxV series. These components are currently in active production status, providing reliable alternatives to the obsolete Nidec part.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series substitutes (PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02) are direct parametric equivalents to the E-TA2012 T 1DB N5. Each substitute maintains identical electrical specifications, mechanical form factor, and regulatory compliance. The primary distinction among the three substitute options is inventory availability, with stock levels ranging from 1004 to 1045 pieces.

Selection between the three substitute parts should be based on procurement requirements and supply chain considerations. All three parts carry active product status from Susumu, ensuring long-term availability and manufacturing support. ROHS3 compliance and REACH unaffected status are maintained across all substitutes, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02 be used interchangeably with E-TA2012 T 1DB N5?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical and mechanical specifications: 1dB attenuation, 0 Hz to 3 GHz frequency range, 50 Ohms impedance, 63mW power rating, and 0805 (2012 Metric) package. Direct substitution is supported without circuit modification.

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

A: The three PxV series parts (PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, PXV1220S-1DBN3-T02) are electrically and mechanically identical. Differences exist only in inventory levels and internal manufacturing lot designations. Selection should be based on procurement availability.

Q: Is the 0805 (2012 Metric) package compatible with existing PCB layouts designed for E-TA2012 T 1DB N5?

A: Yes. All substitute parts use the identical 0805 (2012 Metric) surface-mount package, ensuring footprint and placement compatibility with existing designs.

Q: Are the Susumu substitutes RoHS compliant?

A: Yes. All three PxV series substitutes are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Why is the original E-TA2012 T 1DB N5 marked as obsolete?

A: Nidec Components Corporation has discontinued this part. The active Susumu PxV series equivalents provide continued access to 1dB RF attenuator functionality with identical performance characteristics.
