E-TA2012 T 2DB N8 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 2DB N8 is a 2dB 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 eligibility for the E-TA2012 T 2DB N8 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 2dB (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 (minimum requirement)

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 long-term availability for design continuity.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series substitutes (PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02) are direct parametric equivalents to the E-TA2012 T 2DB N8. The primary advantage of these substitutes is their active production status, ensuring long-term supply chain availability compared to the obsolete Nidec component.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The identical electrical specifications (2dB attenuation, 0 Hz to 3 GHz frequency range, 50 ohm impedance, 63mW power rating) and mechanical package (0805 metric) enable direct board-level substitution without circuit redesign.

Selection among the three Susumu variants may be based on inventory availability and packaging preferences (all are supplied in Tape & Reel format).

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02 be used interchangeably with E-TA2012 T 2DB N8?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical and mechanical specifications: 2dB attenuation, 0 Hz to 3 GHz frequency range, 50 ohm impedance, 63mW power rating, and 0805 (2012 metric) package. Direct substitution is supported without circuit modification.

Q: Why is the E-TA2012 T 2DB N8 marked as obsolete?

A: Nidec Components Corporation has discontinued this part number. The Susumu PxV series alternatives provide equivalent functionality with active production status and improved supply chain continuity.

Q: Are there differences between PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02, and PXV1220S-2DBN3-T02?

A: These three part numbers are parametrically identical. Differences, if any, relate to internal manufacturing variants or date codes. All meet the same electrical and mechanical specifications and are suitable for the same applications.

Q: What is the significance of the packaging format (Tape & Reel)?

A: Tape & Reel (TR) packaging is standard for automated assembly processes. All substitute parts use this format, ensuring compatibility with standard pick-and-place equipment and reflow soldering processes.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. All three Susumu substitutes are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most markets.
