E-TA2012 T 7DB N1 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 7DB N1 is a 7dB 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 obsolete, making identification of active equivalent alternatives essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the E-TA2012 T 7DB N1 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 7dB (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)

All three substitute parts listed below meet these criteria and are manufactured by Susumu under the PxV series. These parts are active products with current inventory availability, providing direct functional replacement for the obsolete E-TA2012 T 7DB N1.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu PxV series substitutes provide parametric equivalence to the E-TA2012 T 7DB N1 across all critical electrical and mechanical specifications. Selection among PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, and PXV1220S-7DBN3-T02 may be based on inventory availability and supply chain considerations:

• PXV1220S-7DBN1-T02: 1485 pcs in stock
• PXV1220S-7DBN2-T02: 630 pcs in stock
• PXV1220S-7DBN3-T02: 751 pcs in stock

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements. The transition from the obsolete Nidec part to any of these active Susumu alternatives presents no compliance or regulatory barriers.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-7DBN1-T02, PXV1220S-7DBN2-T02, and PXV1220S-7DBN3-T02 be used interchangeably with E-TA2012 T 7DB N1?

A: Yes. All three Susumu parts are parametric equivalents meeting identical specifications for attenuation (7dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 metric). They are direct functional replacements.

Q: What is the difference between the three Susumu substitute parts?

A: The three PxV series parts (N1, N2, N3 variants) are parametrically identical across all electrical and mechanical parameters. Differences, if any, relate to internal manufacturing or tape configuration details not specified in the provided data. Selection should be based on inventory availability.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Susumu substitute parts are ROHS3 compliant, matching the compliance status of the original E-TA2012 T 7DB N1.

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

A: All substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are the substitute parts available in Tape & Reel packaging?

A: Yes. All three Susumu substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
