Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 3DB N7 is determined by strict equivalence across the following critical parameters: attenuation value (3dB), 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 electrical and mechanical specifications, ensuring direct functional compatibility. The substitute parts are available in active product status with current inventory, addressing the obsolescence of the original component.

Parameter Comparison

Engineering Selection Recommendations

All three Susumu substitute parts (PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02) are direct parametric equivalents to the E-TA2012 T 3DB N7. Selection among these active alternatives should be based on inventory availability and supply chain requirements. PXV1220S-3DBN3-T02 offers the highest current stock level at 1354 pieces. All substitute parts maintain ROHS3 compliance and identical electrical performance specifications, ensuring seamless integration into existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, and PXV1220S-3DBN3-T02 be used interchangeably with E-TA2012 T 3DB N7?

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

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

A: The three Susumu parts (PXV1220S-3DBN1-T02, PXV1220S-3DBN2-T02, PXV1220S-3DBN3-T02) are parametrically identical. Differences exist only in internal design variants or manufacturing batches, but all meet the same electrical and mechanical specifications.

Q: Are the substitute parts available in the same packaging as the original?

A: The substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface-mount component distribution. The physical package type (0805 2012 Metric) remains identical for PCB assembly compatibility.

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

A: Yes. All substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original component's environmental and regulatory certifications.

Q: Why is the original E-TA2012 T 3DB N7 marked as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The identified Susumu alternatives are active products with current manufacturing support and inventory availability.
