Engineering Selection Recommendations

For RoHS3 Compliant Designs: Select HCPL-2201-000E, HCPL-2201-060E, HCPL-2211-000E, HCPL-2211-060E, or HCPL-7710-020E. All variants carry ROHS3 Compliant certification and maintain active product status with Broadcom.

For Standard (Non-RoHS) Applications: HCPL-2201 and HCPL-2211 base part numbers are available as RoHS non-compliant alternatives with equivalent electrical performance.

For Applications Requiring Enhanced Transient Immunity: HCPL-2211 series (5kV/µs or 10kV/µs CMTI) provides superior noise rejection compared to HCPL-2201 series (1kV/µs CMTI) while maintaining identical isolation voltage and data rate specifications.

For High-Speed Applications with Restricted Supply Voltage: HCPL-7710-020E offers 12.5MBd data rate and 40ns propagation delay but operates within 4.5V ~ 5.5V supply range. This part is suitable only for designs with fixed 5V supply rails and requiring faster signal propagation.

For Isolation Voltage Margin: HCPL-7710-020E provides 5000Vrms isolation, approaching the original SFH6701 specification of 5300Vrms. HCPL-2201 and HCPL-2211 series operate at 3750Vrms, which is acceptable for applications where the original 5300Vrms specification includes design margin.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2201 or HCPL-2211 directly replace SFH6701 in existing designs?

A: Yes, for applications where the isolation voltage requirement is 3750Vrms or lower. Both parts maintain identical single-channel push-pull output topology, 8-DIP package footprint, 5MBd data rate, and -40°C ~ 85°C operating temperature range. The HCPL-2201 and HCPL-2211 supply voltage range extends to 20V, providing additional design flexibility.

Q: What is the difference between HCPL-2201 and HCPL-2211?

A: The primary difference is Common Mode Transient Immunity (CMTI). HCPL-2201 specifies 1kV/µs CMTI, matching the SFH6701. HCPL-2211 specifies 5kV/µs or 10kV/µs CMTI, providing enhanced immunity to high-speed voltage transients on the isolated side. Both maintain identical isolation voltage (3750Vrms), data rate (5MBd), and output current (25 mA).

Q: Why does HCPL-7710-020E have lower output current (10 mA vs 25 mA)?

A: HCPL-7710-020E is optimized for higher data rates (12.5MBd) and faster propagation delay (40ns). The reduced output current reflects the different design architecture. This part is suitable only for applications where 10 mA output current is sufficient and the restricted 4.5V ~ 5.5V supply voltage range is compatible with the system design.

Q: Are tube-packaged variants (HCPL-2201-000E, HCPL-2201-060E, HCPL-2211-000E, HCPL-2211-060E) electrically identical to bulk-packaged parts?

A: Yes. The packaging designation (-000E, -060E, or no suffix) indicates only the physical packaging format (tube vs bulk) and does not affect electrical specifications or performance. Select based on procurement and assembly requirements.

Q: Which substitute part is recommended for new designs?

A: For new designs requiring RoHS3 compliance, HCPL-2201-000E or HCPL-2211-000E are recommended. HCPL-2211-000E is preferred for applications with high-speed transient environments. For designs with fixed 5V supply and requiring maximum speed, HCPL-7710-020E is suitable.

Q: Is the reduced isolation voltage of HCPL-2201/HCPL-2211 (3750Vrms vs 5300Vrms) a concern?

A: Substitution is valid only if the application isolation requirement is 3750Vrms or lower. If the original design specifically requires 5300Vrms isolation margin, HCPL-7710-020E (5000Vrms) is the only substitute meeting this criterion. Consult system safety and regulatory requirements before substitution.

Q: What is the inventory status of these substitute parts?

A: HCPL-2211 base part has the highest inventory (29,004 pcs). HCPL-2201-000E (1,442 pcs) and HCPL-2211-000E (5,695 pcs) are available in RoHS3 compliant tube packaging. HCPL-7710-020E (974 pcs) has limited availability. Verify current stock before design commitment.
