E-TA2012 T 1DB N7 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 1DB N7 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 N7 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 1dB (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 components are manufactured by Susumu under the PxV series and maintain identical electrical and mechanical specifications to the original part.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series components (PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 1DB N7. All substitute parts maintain active product status, ensuring long-term availability and supply chain continuity. Each substitute part carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

The primary distinction among the three Susumu alternatives is inventory availability. Selection between these three parts should be based on procurement lead times and stock requirements, as all three are electrically and mechanically identical. The Tape & Reel packaging format of the substitute parts is standard for automated assembly processes and provides superior handling characteristics compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02 be used interchangeably with E-TA2012 T 1DB N7?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation value (1dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 2012 Metric). They are direct substitutes for circuit design and PCB layout purposes.

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

A: The three parts are electrically and mechanically identical. The designations (N1, N2, N3) represent different manufacturing batches or tape reel configurations. Inventory levels differ: PXV1220S-1DBN1-T02 (1045 Pcs), PXV1220S-1DBN2-T02 (1038 Pcs), and PXV1220S-1DBN3-T02 (1004 Pcs).

Q: Is the 0805 package compatible with existing PCB designs for the E-TA2012 T 1DB N7?

A: Yes. The 0805 (2012 Metric) package specification is identical across all parts. PCB footprints, solder pad dimensions, and component placement are fully compatible.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Susumu substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of Tape & Reel packaging for the substitute parts?

A: Tape & Reel (TR) packaging is the standard format for automated surface-mount assembly. It provides improved handling, reduced component damage during manufacturing, and compatibility with pick-and-place equipment. This is superior to bulk packaging for production environments.
