E-TA2012 T 4DB N3 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 4DB N3 is a 4dB 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 equivalent substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the E-TA2012 T 4DB N3 are qualified based on strict electrical and mechanical parameter matching:

Qualifying Parameters for Substitution:

• Attenuation Value: 4dB (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 and are manufactured by Susumu under the PxV series designation. These components are classified as active products with current manufacturing support and full inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The E-TA2012 T 4DB N3 is obsolete and no longer in active production. Direct substitution is available through three equivalent Susumu PxV series components: PXV1220S-4DBN3-T02, PXV1220S-4DBN1-T02, and PXV1220S-4DBN2-T02. All three substitute parts are active products with identical electrical specifications and mechanical compatibility.

All substitute components maintain ROHS3 compliance and carry REACH Unaffected status, ensuring regulatory alignment with current environmental standards. Selection among the three substitute options may be based on packaging format (all supplied in Tape & Reel configuration) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-4DBN3-T02, PXV1220S-4DBN1-T02, and PXV1220S-4DBN2-T02 be used interchangeably with E-TA2012 T 4DB N3?

A: Yes. All three Susumu components meet identical electrical and mechanical specifications: 4dB attenuation, 0 Hz to 3 GHz frequency range, 50 Ohm impedance, 63mW power rating, and 0805 (2012 Metric) package. They are direct functional equivalents.

Q: What is the difference between the three Susumu substitute part numbers?

A: The three part numbers (PXV1220S-4DBN3-T02, PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02) share identical electrical and mechanical parameters. Differences are limited to internal manufacturing or packaging lot designations. All are functionally equivalent for circuit design purposes.

Q: Are the substitute parts available in the same package format?

A: Yes. All substitute components are supplied in Tape & Reel (TR) packaging, consistent with the original E-TA2012 T 4DB N3 component format for automated assembly operations.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All substitute components are ROHS3 compliant and REACH Unaffected, matching the regulatory status of the original part.

Q: What is the moisture sensitivity level of the substitute parts?

A: All substitute components carry Moisture Sensitivity Level 1 (Unlimited), identical to the original E-TA2012 T 4DB N3.
