Substitute Part Grouping Explanation

Substitution of the HCPL2611V is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 2500Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Configuration: Open Collector topology (mandatory match)
• Common Mode Transient Immunity: 10kV/µs minimum (mandatory match)
• Data Rate: 10Mbps (mandatory match)
• Package Type: 8-DIP form factor (mandatory match)
• Mounting Technology: Through Hole (mandatory match)
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)
• Supply Voltage Range: Compatible with 4.5V ~ 5.5V operation (mandatory match)

The HCPL2611VM qualifies as a direct substitute based on full parameter equivalence across all critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The HCPL2611VM is the recommended substitute for the obsolete HCPL2611V. Both components are manufactured by onsemi and maintain full electrical and mechanical compatibility. The HCPL2611VM carries Active product status, ensuring ongoing availability and manufacturing support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The transition from HCPL2611V to HCPL2611VM requires no circuit redesign, as all critical parameters remain equivalent. The primary difference is the supply voltage specification: HCPL2611VM specifies 5.5V nominal operation, while HCPL2611V supports the broader 4.5V ~ 5.5V range. Applications operating at 5.5V supply voltage experience no functional impact.

Frequently Asked Questions (FAQ)

Q: Can HCPL2611VM directly replace HCPL2611V in existing designs?

A: Yes. The HCPL2611VM is a direct pin-for-pin and functionally equivalent substitute. All critical electrical parameters, including isolation voltage, output current, data rate, propagation delay, and operating temperature range, are identical. The 8-DIP through-hole package is mechanically identical.

Q: What is the primary reason for substitution?

A: The HCPL2611V is classified as obsolete. The HCPL2611VM is the active equivalent from the same manufacturer, ensuring continued supply chain access and manufacturing support.

Q: Are there any supply voltage considerations?

A: The HCPL2611V specifies a supply voltage range of 4.5V ~ 5.5V, while the HCPL2611VM specifies 5.5V. Applications designed for 5.5V operation experience no impact. Applications requiring operation below 5.5V should verify compatibility with the HCPL2611VM datasheet.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both HCPL2611V and HCPL2611VM are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements for industrial and commercial applications.

Q: Is the 8-DIP package identical between both parts?

A: Yes. Both components use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin configuration and mechanical dimensions. No PCB layout modifications are required.
