Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 4DB N1 is determined by strict equivalence across the following electrical and mechanical parameters: attenuation value (4dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). All identified substitute parts from Susumu maintain identical specifications across these critical parameters, ensuring direct functional compatibility. The substitute parts are grouped as direct manufacturer equivalents and parametric equivalents, all meeting ROHS3 compliance and MSL 1 requirements.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu substitute parts (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02) are functionally equivalent to the obsolete E-TA2012 T 4DB N1 across all critical electrical and mechanical parameters. All substitute parts maintain active product status, ensuring long-term availability and supply chain stability. All parts are ROHS3 compliant and carry REACH Unaffected status, meeting current regulatory requirements. Selection among the three Susumu variants should be based on inventory availability and procurement lead times, as electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, and PXV1220S-4DBN3-T02 be used interchangeably with E-TA2012 T 4DB N1?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation (4dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). They are direct functional replacements.

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

A: The three Susumu parts (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, PXV1220S-4DBN3-T02) are parametric equivalents with identical electrical and mechanical specifications. Differences, if any, relate to internal manufacturing variants or date codes and do not affect functional performance.

Q: Is the 0805 package compatible with existing PCB designs for the E-TA2012 T 4DB N1?

A: Yes. All substitute parts use the same 0805 (2012 Metric) surface-mount package, ensuring direct compatibility with existing PCB layouts and assembly processes.

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 moisture sensitivity level of the substitute parts?

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