Substitute Part Grouping Explanation

Substitute parts for the E-TA2012 T 1DB N4 are qualified based on strict parametric equivalence across the following criteria:

• 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 / Case: 0805 (2012 Metric) (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All three substitute parts listed below meet these criteria and are manufactured by Susumu under the PxV series designation.

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 N4. All substitute parts maintain active product status, ensuring long-term availability and supply chain stability. All parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The substitute parts are supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02 be used interchangeably with E-TA2012 T 1DB N4?

A: Yes. All three Susumu parts are parametric equivalents meeting identical electrical specifications (1dB attenuation, 0 Hz ~ 3 GHz frequency range, 50-ohm impedance, 63mW power rating) and mechanical specifications (0805 package). They are suitable for direct substitution in PCB designs.

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

A: PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02, and PXV1220S-1DBN3-T02 share identical electrical and mechanical parameters. The designations N1, N2, and N3 represent internal Susumu manufacturing variants. All three are functionally equivalent for circuit applications.

Q: Are there packaging differences between the main part and substitutes?

A: The E-TA2012 T 1DB N4 packaging format is not specified in available documentation. The Susumu substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume production and automated assembly. Verify packaging requirements for your specific manufacturing process.

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

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original E-TA2012 T 1DB N4. Both the original and substitute parts carry EAR99 ECCN classification and 8533.21.0020 HTSUS code.

Q: Why is the original part listed as obsolete?

A: The E-TA2012 T 1DB N4 is classified as obsolete by Nidec Components Corporation. The active Susumu PxV series parts provide equivalent functionality with confirmed long-term availability, making them the recommended choice for new designs and ongoing production.
