Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVI5050NPBF is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 4000Vrms
• Output type: Photovoltaic
• Number of channels: 1
• Package configuration: 8-DIP (0.300", 7.62mm), 4 Leads
• Operating temperature range: -40°C ~ 85°C
• Input type: DC
• Mounting type: Through Hole

The PVI5080NPBF qualifies as a direct substitute based on matching all isolation, output type, channel count, package, temperature, and mounting specifications. The primary difference is the output current specification, where the PVI5080NPBF provides 8µA compared to the PVI5050NPBF's 5µA, representing an enhancement in output current capability while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The PVI5080NPBF is the qualified substitute for the obsolete PVI5050NPBF. Selection of the PVI5080NPBF is supported by the following factors:

• Active product status ensures ongoing availability and manufacturing support
• Full compliance with ROHS3 and REACH requirements matches the original component
• Identical isolation voltage, package, and thermal specifications maintain design compatibility
• Enhanced output current (8µA versus 5µA) provides improved performance margin without introducing incompatibility
• Both components share identical turn-on/turn-off timing characteristics

The transition from PVI5050NPBF to PVI5080NPBF requires no circuit redesign when the higher output current is acceptable within the application's design parameters.

Frequently Asked Questions (FAQ)

Q: Can the PVI5080NPBF directly replace the PVI5050NPBF in existing designs?

A: Yes. The PVI5080NPBF maintains identical isolation voltage (4000Vrms), output voltage (5V maximum), package configuration (8-DIP), and timing specifications. The increased output current (8µA versus 5µA) is a performance enhancement that does not create incompatibility.

Q: What is the primary difference between these two parts?

A: The output current per channel differs: PVI5050NPBF provides 5µA while PVI5080NPBF provides 8µA. All other electrical and mechanical specifications are identical.

Q: Are both parts available in the same packaging?

A: Yes. Both the PVI5050NPBF and PVI5080NPBF use 8-DIP (0.300", 7.62mm) through-hole packaging with 4 leads, ensuring identical PCB footprint compatibility.

Q: What is the isolation rating for these optoisolators?

A: Both components provide 4000Vrms isolation voltage, suitable for high-voltage isolation applications.

Q: Are there any compliance differences between these parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Why is the PVI5050NPBF listed as obsolete?

A: The PVI5050NPBF has been discontinued by Infineon Technologies. The PVI5080NPBF remains in active production and serves as the current equivalent offering.
