Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 3DB N4 is determined by strict equivalence across the following electrical and mechanical parameters:

• Attenuation Value: 3dB (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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All substitute parts listed below meet these criteria without exception. The Susumu PxV series components are parametric equivalents with active product status, providing direct functional replacement capability.

Parameter Comparison

Engineering Selection Recommendations

The E-TA2012 T 3DB N4 is obsolete and no longer in active production. Direct replacement is available through the Susumu PxV series attenuators: PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02. All three alternatives are active products with identical electrical specifications and mechanical compatibility.

Selection among the three Susumu variants should be based on inventory availability and supply chain requirements. All three parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The PXV1220S-3DBN3-T02 variant currently has the highest inventory level at 1354 pieces.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02 be used interchangeably with E-TA2012 T 3DB N4?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation value (3dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). They provide direct functional replacement without circuit modification.

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

A: The three Susumu variants (PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, PXV1220S-3DBN3-T02) are parametrically identical. Differences are limited to internal design variants within the PxV series. Selection should be based on supply availability and procurement lead times.

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

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging and are compatible with standard pick-and-place assembly equipment. The 0805 (2012 Metric) package footprint is identical across all parts.

Q: Do the substitute parts meet current compliance requirements?

A: Yes. All three Susumu alternatives are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components in regulated markets.

Q: Why are there three different part numbers for functionally identical components?

A: The three variants represent different design iterations or manufacturing batches within the Susumu PxV series. All maintain identical electrical and mechanical specifications, allowing flexible sourcing based on inventory and availability.
