Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-0723-060E is determined by the following critical parameters:

• Isolation Voltage: Must be 3750Vrms or higher
• Output Configuration: Must be push-pull, totem pole topology
• Package: Must be 8-SOIC with 0.154" width (3.90mm)
• Supply Voltage: Must support 4.5V ~ 5.5V range
• Number of Channels: Must be single channel (1 channel)
• Input Type: Must be logic input
• Output Current: Must support minimum 10 mA per channel

Substitute parts are grouped by data rate capability. The HCPL-0723-060E operates at 50MBd. Substitute parts with equal or higher data rates (12.5Mbps, 25Mbps) are functionally compatible, as they meet or exceed the isolation and switching performance requirements while maintaining identical package and electrical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing support, eliminating obsolescence risk associated with the HCPL-0723-060E. Selection among substitutes should be based on the following criteria:

FOD0710 and FOD0710R2 (12.5Mbps): Suitable for applications where data rate requirements do not exceed 12.5Mbps. These parts provide the lowest data rate among substitutes and are available from both Fairchild Semiconductor and onsemi.

FOD0720 and FOD0720R2 (25Mbps): Recommended for mid-range data rate applications up to 25Mbps. Available from Fairchild Semiconductor in bulk and standard packaging.

FOD0721 and FOD0721R2 (25Mbps): Equivalent to FOD0720 series in electrical performance, manufactured by onsemi. FOD0721R2 is supplied in tape and reel packaging; FOD0721 is supplied in tube packaging. Both carry ROHS3 compliance and MSL 1 rating.

All substitute parts exceed the original part's common mode transient immunity specification (20kV/µs versus 10kV/µs), providing enhanced noise immunity. All substitute parts support the extended operating temperature range of -40°C to 100°C, compared to the original part's -40°C to 85°C range.

Frequently Asked Questions (FAQ)

Q: Can FOD0710 or FOD0710R2 be used as direct replacements for HCPL-0723-060E?

A: Yes. Both parts meet all critical substitution parameters: 3750Vrms isolation, push-pull totem pole output, 8-SOIC package, 10 mA output current, and 4.5V to 5.5V supply voltage. The 12.5Mbps data rate is lower than the original 50MBd specification, so application timing requirements must be verified to ensure compatibility.

Q: What is the difference between FOD0720 and FOD0721?

A: Both parts are electrically identical with 25Mbps data rate and identical electrical specifications. The primary difference is manufacturer: FOD0720 is manufactured by Fairchild Semiconductor, while FOD0721 is manufactured by onsemi. Packaging options differ: FOD0720 is available in bulk; FOD0721 is available in tube or tape and reel formats.

Q: Are FOD0720R2 and FOD0721R2 interchangeable?

A: Yes. Both parts have identical electrical specifications, 25Mbps data rate, and 8-SOIC package. The R2 suffix indicates tape and reel packaging. FOD0720R2 is from Fairchild Semiconductor; FOD0721R2 is from onsemi. Selection can be based on supplier availability and procurement preferences.

Q: Does the higher common mode transient immunity (20kV/µs) of substitute parts affect circuit design?

A: No. Higher CMTI specification indicates improved performance and noise immunity. Circuits designed for the original 10kV/µs specification will operate correctly with substitute parts rated at 20kV/µs.

Q: Can I use FOD0710 in a design that originally specified HCPL-0723-060E?

A: Electrical compatibility is confirmed. However, the data rate is reduced from 50MBd to 12.5Mbps. Verify that your application's timing and signal frequency requirements do not exceed 12.5Mbps. If higher data rates are required, use FOD0720 or FOD0721 (25Mbps).

Q: What is the significance of the R2 suffix in part numbers?

A: The R2 suffix indicates the second revision of the part design. Parts with R2 designation are current production versions. FOD0710R2, FOD0720R2, and FOD0721R2 are recommended for new designs due to active production status and current compliance certifications.

Q: Are all substitute parts ROHS3 compliant?

A: FOD0710R2, FOD0721, and FOD0721R2 carry explicit ROHS3 compliance certification. FOD0710, FOD0720, and FOD0720R2 do not have RoHS status specified in available documentation. Verify RoHS compliance requirements with your procurement or quality department before final part selection.
