Key Parameters

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 2DB N3 is determined by strict equivalence across the following critical parameters: attenuation value (2dB), 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 functional interchangeability within the design envelope. The primary distinction among substitutes lies in product status and packaging configuration, with all active alternatives offering ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the E-TA2012 T 2DB N3, the Susumu PxV series attenuators (PXV1220S-2DBN3-T02, PXV1220S-2DBN1-T02, and PXV1220S-2DBN2-T02) provide direct functional equivalence. All substitute parts maintain identical electrical performance specifications and mechanical compatibility. The primary advantage of these alternatives is their active product status, ensuring long-term availability and supply chain stability compared to the obsolete Nidec component. All substitutes carry ROHS3 compliance and REACH Unaffected certification, meeting current regulatory requirements. Selection among the three Susumu variants should be based on packaging configuration requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-2DBN3-T02, PXV1220S-2DBN1-T02, and PXV1220S-2DBN2-T02 be used interchangeably with E-TA2012 T 2DB N3?

A: Yes. All three Susumu parts are parametric equivalents with identical attenuation (2dB), frequency range (0 Hz ~ 3 GHz), impedance (50 Ohms), power rating (63mW), and package type (0805 / 2012 Metric). Electrical and mechanical interchangeability is confirmed.

Q: What is the difference between the three Susumu substitute part numbers?

A: The three Susumu variants (PXV1220S-2DBN3-T02, PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02) share identical electrical specifications and package configuration. Differences are limited to internal design variants and packaging lot designations. All are functionally equivalent for circuit applications.

Q: Is the 0805 (2012 Metric) package compatible with existing PCB layouts designed for E-TA2012 T 2DB N3?

A: Yes. All substitute parts use the identical 0805 (2012 Metric) surface-mount package, ensuring direct footprint compatibility without PCB redesign.

Q: Are the Susumu substitutes RoHS compliant?

A: Yes. All three Susumu alternatives (PXV1220S-2DBN3-T02, PXV1220S-2DBN1-T02, PXV1220S-2DBN2-T02) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the original E-TA2012 T 2DB N3 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Nidec Components Corporation. Active alternatives from Susumu provide equivalent functionality with assured long-term availability.
