Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICPL2631 is determined by the following critical parameters:

• Number of Channels: Must be 2 channels
• Voltage - Isolation: Minimum 5000Vrms (higher isolation ratings are acceptable)
• Current - Output / Channel: Minimum 50mA
• Operating Temperature Range: Must encompass -40°C ~ 100°C
• Package / Case: Must be 8-DIP (0.300", 7.62mm)
• Mounting Type: Must be Through Hole
• Product Status: Must be Active
• RoHS Compliance: Must maintain ROHS3 Compliant status

The VO2631 meets all substitution criteria with equivalent or superior electrical characteristics and identical mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The VO2631 qualifies as a direct substitute for the ICPL2631 based on the following factors:

• Both parts maintain Active product status with continuous manufacturing support
• Both achieve ROHS3 compliance and REACH unaffected status
• Identical package specifications (8-DIP through-hole) ensure mechanical compatibility
• Operating temperature ranges are identical (-40°C ~ 100°C)
• Output current capability matches at 50mA per channel
• Isolation voltage of VO2631 (5300Vrms) exceeds the ICPL2631 requirement (5000Vrms)

The primary design consideration is the difference in output type: ICPL2631 provides transistor output while VO2631 provides open drain output. This distinction requires circuit-level evaluation to confirm compatibility with the intended application.

Frequently Asked Questions (FAQ)

Q: Can the VO2631 be used as a direct pin-for-pin replacement for the ICPL2631?

A: Both parts use the 8-DIP package with identical pinout spacing (0.300", 7.62mm). However, the output type differs (transistor vs. open drain), which may require circuit modifications depending on the application design.

Q: What is the significance of the higher isolation voltage in the VO2631?

A: The VO2631 provides 5300Vrms isolation compared to the ICPL2631's 5000Vrms. This exceeds the minimum requirement and provides additional safety margin in high-voltage isolation applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the ICPL2631 and VO2631 operate across -40°C to 100°C, making them functionally equivalent for temperature-dependent applications.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.49.8000.

Q: How do the forward voltage characteristics compare?

A: The typical forward voltage (Vf) is 1.4V for ICPL2631 and 1.42V for VO2631, representing negligible difference. The maximum DC forward current differs slightly (20mA vs. 15mA), with ICPL2631 rated higher.

Q: Is inventory availability a factor in substitution?

A: The VO2631 has 1711 units in stock compared to 1162 units for ICPL2631, providing greater availability for high-volume applications.
