Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E-TA3216 3DB N7 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Attenuation Value: Must be 3dB
• 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) SMD format
• RoHS Compliance: Must meet ROHS3 standard
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The PBV1632S-3DBN7 from Susumu meets all specified parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

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

The primary distinction is product status: the E-TA3216 3DB N7 is obsolete, while the PBV1632S-3DBN7 is active production. For new designs and ongoing system support, the Susumu component provides equivalent performance with assured supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the PBV1632S-3DBN7 be used as a direct replacement for the E-TA3216 3DB N7?

A: Yes. Both components meet identical electrical and mechanical specifications: 3dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 100mW power rating, and 1206 package format. Pin-to-pin and footprint compatibility is confirmed.

Q: What is the primary reason for seeking a substitute?

A: The E-TA3216 3DB N7 is classified as obsolete. The PBV1632S-3DBN7 is an active production component with confirmed supply availability.

Q: Are there compliance differences between these components?

A: No. Both components are ROHS3 compliant with MSL 1 moisture sensitivity classification. Both carry EAR99 ECCN designation.

Q: Does package format remain the same?

A: Yes. Both components use the 1206 (3216 Metric) SMD package format, ensuring identical PCB footprint and assembly compatibility.
