E-TA2012 T 1DB N8 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 1DB N8 is a 1dB RF attenuator manufactured by Nidec Components Corporation, designed for applications requiring signal attenuation in the 0 Hz to 3 GHz frequency range. This component operates at 50 Ohm 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 active equivalent alternatives essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

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

All three 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 compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series parts (PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02) are direct parametric equivalents to the E-TA2012 T 1DB N8. All substitute parts maintain identical electrical specifications and physical package dimensions while offering the advantage of active production status. Each substitute part carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The availability of three variants from the same manufacturer series provides supply chain flexibility. Selection among the three Susumu variants should be based on procurement lead times and inventory availability, as all three are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02 be used interchangeably with E-TA2012 T 1DB N8?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation (1dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package (0805 2012 Metric). They are direct substitutes for PCB layout and electrical performance.

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

A: The three parts (PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, PXV1220S-1DBN3-T02) are electrically and mechanically identical. The suffix variation (N1, N2, N3) reflects internal manufacturing or distribution designations. All three are supplied in Tape & Reel packaging and are functionally interchangeable.

Q: Why is the original E-TA2012 T 1DB N8 marked as obsolete?

A: Nidec Components Corporation has discontinued this part number. The active Susumi PxV series alternatives provide equivalent performance with ongoing manufacturing support and availability.

Q: Are the substitute parts RoHS compliant?

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

Q: What is the MSL rating for these parts?

A: All parts, including the original and substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
