E-TA2012 T 3DB N8 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 3DB N8 is an RF attenuator manufactured by Nidec Components Corporation, designed for RF signal attenuation applications across the 0 Hz to 3 GHz frequency range. This component operates at 50 Ohms impedance with 3dB attenuation and 63mW power handling 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.

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 3DB N8 is determined by strict equivalence across the following electrical and mechanical 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: 0805 (2012 Metric) (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria and are manufactured by Susumu under the PxV series. These parts 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-3DBN1-T02, PXV1220S-3DBN2-T02, PXV1220S-3DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 3DB N8. Selection among these active alternatives should be based on:

• Product Status: All substitute parts are in active production, ensuring long-term availability and supply chain stability compared to the obsolete Nidec component.
• Compliance: All substitutes maintain ROHS3 compliance and identical electrical/mechanical specifications.
• Inventory Availability: PXV1220S-3DBN3-T02 offers the highest current stock level (1354 Pcs), followed by PXV1220S-3DBN1-T02 (973 Pcs) and PXV1220S-3DBN2-T02 (740 Pcs).
• Packaging: All substitutes are supplied in Tape & Reel format, standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02 be used interchangeably with E-TA2012 T 3DB N8?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical specifications (3dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohms impedance, 63mW power rating) and mechanical requirements (0805 package, ROHS3 compliance, MSL 1). They are functionally interchangeable in circuit applications.

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

A: These three part numbers represent variants within the Susumu PxV series with identical electrical and mechanical parameters. Differences are limited to internal design variations or manufacturing batches. All meet the same performance specifications for RF attenuation applications.

Q: Why is the original E-TA2012 T 3DB N8 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production by Nidec Components Corporation. The listed Susumu alternatives provide equivalent functionality with the advantage of active production status and ongoing availability.

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

A: No. All parts maintain identical ROHS3 compliance, MSL 1 rating, EAR99 export classification, and HTSUS code 8533.21.0020. Compliance requirements are fully satisfied by any of the listed substitutes.

Q: What packaging format is used for the substitute parts?

A: All Susumu substitutes are supplied in Tape & Reel (TR) format, standard for high-volume automated assembly and pick-and-place operations.
