Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E-TA3216 4DB N7 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: Must be 4dB
• Frequency Range: Must cover 0 Hz ~ 3 GHz minimum
• Impedance: Must be 50 Ohms
• Power Rating: Must be 100mW or greater
• Package / Case: Must be 1206 (3216 Metric)
• RoHS Compliance: Must meet ROHS3 standard
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The substitute part PBV1632S-4DBN7 from Susumu meets all specified parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The PBV1632S-4DBN7 from Susumu is qualified as a direct substitute for the obsolete E-TA3216 4DB N7. Both components share identical electrical specifications (4dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 100mW power rating) and mechanical compatibility (1206 package). Both meet ROHS3 compliance requirements and carry MSL 1 moisture sensitivity rating.

The primary advantage of selecting the PBV1632S-4DBN7 is its active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Nidec component.

Frequently Asked Questions (FAQ)

Q: Can the PBV1632S-4DBN7 be used as a direct replacement for the E-TA3216 4DB N7?

A: Yes. Both components meet identical specifications for attenuation value, frequency range, impedance, power rating, and package type. No circuit modifications are required.

Q: Are there any compliance differences between these parts?

A: Both components are ROHS3 compliant and carry MSL 1 moisture sensitivity rating. The Susumu part includes REACH Unaffected status, providing additional regulatory documentation.

Q: Does package compatibility require any PCB layout changes?

A: No. Both parts use the 1206 (3216 Metric) surface mount package, ensuring identical footprint and placement compatibility on existing PCB designs.

Q: Why is the original Nidec part listed as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions. The Susumi equivalent remains in active production, supporting continued component availability.
