Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitution:

• Attenuation Value: Must match exactly at 2dB
• Frequency Range: Must cover or exceed 0 Hz ~ 3 GHz
• Impedance: Must be 50 Ohms
• Power Rating: Must be 100mW or greater
• Package / Case: Must be 1206 (3216 Metric) for PCB compatibility
• Moisture Sensitivity Level: Must be MSL 1 or equivalent
• RoHS Compliance: Must maintain ROHS3 Compliant status

The substitute part PBV1632S-2DBN7 from Susumu meets all specified parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The PBV1632S-2DBN7 from Susumu is a direct substitute for the obsolete E-TA3216 2DB N7. Both components share identical electrical specifications (2dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 100mW power rating) and mechanical compatibility (1206 package). Both maintain ROHS3 compliance and MSL 1 rating. The Susumu part carries active product status with current inventory availability, making it the appropriate selection for applications requiring the E-TA3216 2DB N7 specification.

Frequently Asked Questions (FAQ)

Q: Can the PBV1632S-2DBN7 be used as a direct replacement for the E-TA3216 2DB N7?

A: Yes. Both components meet identical electrical and mechanical specifications: 2dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohm impedance, 100mW power rating, and 1206 package format. No circuit modifications are required.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 rating. The Susumi part carries additional REACH Unaffected status. Compliance requirements are met by both components.

Q: What is the significance of the product status difference?

A: The E-TA3216 2DB N7 is obsolete, indicating discontinued manufacturing and limited availability. The PBV1632S-2DBN7 maintains active status with current production and inventory support, ensuring long-term procurement viability.

Q: Are there any frequency or impedance limitations when substituting?

A: No. Both parts operate identically across the 0 Hz ~ 3 GHz frequency range with 50 Ohm impedance. Substitution does not introduce frequency or impedance constraints.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both components use the 1206 (3216 Metric) surface mount package with identical pinout and footprint compatibility. No PCB layout modifications are necessary.
