E-TA2012 T 1DB N3 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 1DB N3 is an RF attenuator manufactured by Nidec Components Corporation, designed for applications requiring 1dB attenuation across the 0 Hz to 3 GHz frequency range. This component operates at 50 Ohms impedance with 63mW power handling capability in a compact 0805 (2012 Metric) surface-mount package. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing system support, maintenance, and new design implementations where this specification remains applicable.

Substitute Part Grouping Explanation

Substitute parts for the E-TA2012 T 1DB N3 are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• 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 Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria without exception. The substitutes are classified as direct manufacturer equivalents from Susumu, maintaining identical electrical performance and mechanical compatibility with the original E-TA2012 T 1DB N3 specification.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu substitute parts (PXV1220S-1DBN3-T02, PXV1220S-1DBN1-T02, and PXV1220S-1DBN2-T02) are direct electrical and mechanical equivalents to the obsolete E-TA2012 T 1DB N3. All substitute parts maintain active product status with Susumu, ensuring long-term availability and supply chain continuity. Each substitute part carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The selection among the three Susumu alternatives should be based on inventory availability and procurement lead times, as all three parts are electrically and mechanically identical. All substitute parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PXV1220S-1DBN3-T02, PXV1220S-1DBN1-T02, and PXV1220S-1DBN2-T02 be used interchangeably with E-TA2012 T 1DB N3?

A: Yes. All three Susumu parts are direct substitutes meeting identical electrical specifications (1dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohms impedance, 63mW power rating) and mechanical requirements (0805 package). They are functionally interchangeable in circuit applications.

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

A: The three Susumu parts (PXV1220S-1DBN3-T02, PXV1220S-1DBN1-T02, PXV1220S-1DBN2-T02) are electrically and mechanically identical. The suffix variations (N1, N2, N3) represent different manufacturing batches or internal Susumu designations but do not affect performance or compatibility.

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 for electronic component procurement.

Q: What packaging format do the substitute parts use?

A: All three Susumu substitute parts are supplied in Tape & Reel (TR) packaging, standard for automated surface-mount assembly processes. The original E-TA2012 T 1DB N3 packaging format was not specified in available documentation.

Q: Why is the original E-TA2012 T 1DB N3 marked as obsolete?

A: The E-TA2012 T 1DB N3 has been discontinued by Nidec Components Corporation. The active Susumu equivalents (PXV1220S series) provide continued availability for this 1dB RF attenuator specification.
