Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E-TA3216 1DB N7 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Attenuation Value: Must be 1dB
• Frequency Range: Must cover 0 Hz ~ 3 GHz minimum
• Impedance: Must be 50 Ohms
• Power Rating: Must be 100mW or greater
• Package: Must be 1206 (3216 Metric) surface-mount format
• Environmental Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Parts meeting all these parameters are electrically and mechanically interchangeable with the original E-TA3216 1DB N7 specification.

Parameter Comparison

Engineering Selection Recommendations

The PBV1632S-1DBN7 manufactured by Susumu meets all electrical and mechanical parameters specified for the E-TA3216 1DB N7. Both components are ROHS3 compliant with identical MSL 1 ratings, ensuring equivalent environmental performance and handling requirements.

The primary distinction is product status: the E-TA3216 1DB N7 is obsolete, while the PBV1632S-1DBN7 maintains active production status. The PBV1632S-1DBN7 is available in higher inventory quantities (1050 Pcs) compared to remaining E-TA3216 1DB N7 stock (748 Pcs), supporting long-term supply chain continuity.

Selection of the PBV1632S-1DBN7 as a substitute is supported by complete parameter equivalence and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: What makes the PBV1632S-1DBN7 a valid substitute for the E-TA3216 1DB N7?

A: Both components share identical electrical specifications (1dB attenuation, 0 Hz ~ 3 GHz frequency range, 50 Ohms impedance, 100mW power rating) and mechanical packaging (1206 / 3216 Metric). Both maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings, ensuring functional and environmental equivalence.

Q: Are there any package or footprint differences between these parts?

A: No. Both the E-TA3216 1DB N7 and PBV1632S-1DBN7 use the 1206 (3216 Metric) surface-mount package format, ensuring identical PCB footprint compatibility and assembly process requirements.

Q: Why is the E-TA3216 1DB N7 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The PBV1632S-1DBN7 remains in active production, providing continued availability and manufacturer technical support.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture control requirements during storage or handling. Standard ESD precautions apply to both parts.

Q: Can the PBV1632S-1DBN7 be used as a direct replacement in existing designs?

A: Yes. Electrical and mechanical parameter equivalence permits direct substitution without design modification. PCB layout and assembly processes remain unchanged.
