FOD0710R2 Equivalent & Substitute Parts
Part Overview
The FOD0710R2 is a logic output optoisolator manufactured by onsemi, featuring 3.75kV isolation voltage with push-pull totem pole output configuration. This single-channel device operates at 12.5Mbps data rate and supports 20kV/µs common mode transient immunity in an 8-SOIC surface mount package. The part is active and ROHS3 compliant with unlimited moisture sensitivity rating.
Substitute parts are necessary when the FOD0710R2 becomes unavailable, when alternative packaging formats are required for production efficiency, or when design specifications allow for compatible performance parameters within the same functional category.

Engineering Selection Recommendations
For Direct Electrical Equivalence (12.5MBd Data Rate):
HCPL-0710-560E is the primary substitute when maintaining identical data rate specification. This part matches the FOD0710R2 in Tape & Reel packaging format, operates across the same supply voltage and temperature range, and carries ROHS3 compliance certification. Inventory availability is comparable at 2938 units.
HCPL-0710-000E and HCPL-0710-500E provide equivalent electrical performance with alternative packaging formats (Tube and Cut Tape & Digi-Reel respectively). Both are ROHS3 compliant and support the full operating temperature range.
For Higher Data Rate Applications (25MBd):
HCPL-0720-500E and ACPL-072L-560E offer doubled data rate capability while maintaining all other electrical parameters. HCPL-0720-500E operates within the original -40°C to 85°C temperature window, whereas ACPL-072L-560E extends the upper temperature limit to 105°C and supports dual supply voltage ranges (3V ~ 3.6V and 4.5V ~ 5.5V). Both are ROHS3 compliant with substantial inventory availability.
Compliance Considerations:
All recommended substitutes carry ROHS3 compliance status matching the FOD0710R2. Parts designated as RoHS non-compliant (HCPL-0710 and HCPL-0720 without suffix) should be selected only when legacy design requirements or specific application constraints mandate their use.
Frequently Asked Questions (FAQ)
Q: Can HCPL-0720 series parts replace FOD0710R2 in existing designs?
A: Yes, provided the application does not require the 20kV/µs common mode transient immunity specification of the FOD0710R2. HCPL-0720 series devices operate at 10kV/µs CMTI and 25MBd data rate. All other electrical and mechanical parameters remain compatible. Temperature range limitation to -40°C ~ 85°C must be verified against application requirements.
Q: What is the difference between HCPL-0710-560E and HCPL-0710-500E?
A: Both parts are electrically identical with matching data rate, isolation voltage, and operating specifications. The difference is packaging format: HCPL-0710-560E is supplied in Tape & Reel (TR) format, while HCPL-0710-500E is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on production equipment compatibility and volume requirements.
Q: Are ACPL-072L series parts pin-compatible with FOD0710R2?
A: Yes. ACPL-072L series devices maintain the 8-SOIC package configuration with identical pinout. The primary differences are higher data rate (25MBd), extended temperature range (-40°C ~ 105°C), and dual supply voltage support (3V ~ 3.6V and 4.5V ~ 5.5V). These enhancements provide design flexibility without requiring PCB modifications.
Q: Why does FOD0710R2 specify 20kV/µs CMTI while substitutes specify 10kV/µs?
A: The FOD0710R2 offers enhanced common mode transient immunity performance. Substitutes with 10kV/µs CMTI remain functionally compatible for applications not requiring the higher immunity specification. Applications with stringent noise immunity requirements should retain the FOD0710R2 or verify that 10kV/µs meets system-level EMC specifications.
Q: Can I use ACPL-072L-560E in a 3.3V supply application?
A: Yes. ACPL-072L-560E supports dual supply voltage ranges including 3V ~ 3.6V, making it suitable for 3.3V systems. FOD0710R2 and HCPL-0710/HCPL-0720 series are specified for 4.5V ~ 5.5V operation only and are not recommended for 3.3V applications.
