E-TA2012 T 1DB N1 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 1DB N1 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 currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 1DB N1 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 substitute parts listed below meet these criteria without exception. The three Susumu PxV series components (PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, PXV1220S-1DBN3-T02) are direct parametric equivalents with identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series attenuators (PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, PXV1220S-1DBN3-T02) are direct substitutes for the obsolete E-TA2012 T 1DB N1. All substitute parts maintain active product status with confirmed ROHS3 compliance and REACH unaffected certification. Electrical performance and mechanical compatibility are identical across all parameters. Selection among the three Susumu variants may be based on inventory availability or procurement lead time, as all three are functionally interchangeable for this application.

Frequently Asked Questions (FAQ)

Q: Can the Susumu PxV series parts be used as direct replacements for the E-TA2012 T 1DB N1?

A: Yes. The PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02 are parametric equivalents with identical attenuation value, frequency range, impedance, power rating, and package specifications.

Q: Are there any differences between the three Susumu substitute parts?

A: All three Susumu parts are electrically and mechanically identical. Differences exist only in inventory levels and internal part designations (N1, N2, N3 suffixes).

Q: What is the significance of the obsolete status of the original part?

A: The E-TA2012 T 1DB N1 is no longer manufactured by Nidec Components Corporation. The listed Susumu alternatives are active products with ongoing production and supply availability.

Q: Are the substitute parts compatible with existing PCB layouts designed for the E-TA2012 T 1DB N1?

A: Yes. All substitute parts use the identical 0805 (2012 Metric) package footprint, ensuring direct compatibility with existing PCB designs without layout modifications.

Q: What compliance certifications apply to the substitute parts?

A: All Susumu substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original part.
