E-TA2012 T 1DB N2 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 1DB N2 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 63mW power handling capability in a compact 0805 (2012 Metric) surface-mount package. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA2012 T 1DB N2 is determined by strict equivalence across the following critical 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)

All substitute parts listed below meet these criteria without deviation. The primary distinction between the main part and substitutes is product status: the original E-TA2012 T 1DB N2 is obsolete, while all substitute parts maintain active production status.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series parts (PXV1220S-1DBN2-T02, PXV1220S-1DBN1-T02, and PXV1220S-1DBN3-T02) are direct functional equivalents to the obsolete E-TA2012 T 1DB N2. All substitute parts maintain active production status, ensuring long-term availability and supply chain stability. Each substitute part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Selection among the three Susumu alternatives should be based on procurement availability and lead time, as all three parts are parametrically identical and interchangeable at the circuit level. The Tape & Reel packaging format of the substitute parts is standard for high-volume surface-mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Are the Susumu PxV series parts direct pin-for-pin replacements for the E-TA2012 T 1DB N2?

A: Yes. All substitute parts share identical package geometry (0805 / 2012 Metric), electrical specifications (1dB attenuation, 50 ohms, 0 Hz ~ 3 GHz), and power rating (63mW). No circuit redesign or PCB layout modification is required.

Q: What is the difference between PXV1220S-1DBN2-T02, PXV1220S-1DBN1-T02, and PXV1220S-1DBN3-T02?

A: These three parts are parametrically equivalent. The suffix variation (N1, N2, N3) reflects manufacturing or packaging lot designations but does not affect electrical performance or mechanical compatibility.

Q: Does the Tape & Reel packaging of substitute parts affect compatibility?

A: No. Tape & Reel is a standard packaging format for automated surface-mount assembly. The component itself is identical to the original part; only the delivery format differs.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three Susumu alternatives are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What inventory levels are available for the substitute parts?

A: PXV1220S-1DBN2-T02: 1038 pcs; PXV1220S-1DBN1-T02: 1045 pcs; PXV1220S-1DBN3-T02: 1004 pcs. All are listed as new original stock.
