HCPL-0720-060E Equivalent & Substitute Parts

Part Overview

The HCPL-0720-060E is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 3750Vrms isolation device features a single channel with push-pull, totem pole output configuration and supports data rates up to 25MBd. The part is currently active in production with 1007 units in stock.

Substitute parts are necessary when the original HCPL-0720-060E becomes unavailable, when alternative packaging formats are required, or when design flexibility across multiple manufacturers is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-0720-060E is determined by the following critical parameters:

• Isolation Voltage: 3750Vrms (all substitutes must match)
• Number of Channels: 1 channel (single-channel configuration required)
• Output Configuration: Push-Pull, Totem Pole (output stage topology must match)
• Package Type: 8-SOIC form factor (physical compatibility)
• Data Rate: 25MBd or higher (backward compatible)
• Supply Voltage Range: 4.5V ~ 5.5V (primary operating range)
• Output Current: 10 mA per channel

Substitute parts are grouped into two categories:

Category A - Direct Functional Equivalents (Same Channel Count & Data Rate) Parts maintaining identical channel configuration and 25MBd data rate with matching isolation voltage and output topology.

Category B - Enhanced Performance Variants (Higher CMTI or Extended Temperature) Parts with superior common mode transient immunity or extended operating temperature ranges while maintaining core electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement)

FOD0720, FOD0720R2, FOD0721, and FOD0721R2 are direct functional substitutes for the HCPL-0720-060E. All maintain single-channel configuration, 3750Vrms isolation, push-pull output topology, 25MBps data rate, and 8-SOIC packaging. These parts are ROHS3 compliant and carry identical regulatory certifications (EAR99, HTSUS 8541.49.8000). The FOD series variants offer enhanced common mode transient immunity (20kV/µs versus 10kV/µs) and extended operating temperature ranges (-40°C to 100°C versus -40°C to 85°C), providing superior performance margins in high-noise environments.

Secondary Substitutes (Reduced Data Rate)

FOD0710 and FOD0710R2 operate at 12.5Mbps, half the data rate of the HCPL-0720-060E. These parts are suitable only for applications where the lower bandwidth is acceptable. All other electrical and mechanical parameters remain compatible.

Alternative Configuration (Multi-Channel)

ACSL-7210-06RE is a dual-channel optoisolator from Broadcom with 3750Vrms isolation and 25MBps data rate. This part is not a direct substitute due to its two-channel configuration but may be considered for designs requiring multiple isolated channels within a single package. It supports dual supply voltage ranges (3.0-3.6V and 4.5-5.5V) and operates to 105°C.

Packaging Considerations

FOD0720R2 and FOD0721R2 are supplied in Tape & Reel format, suitable for high-volume automated assembly. FOD0720 and FOD0721 are available in Bulk packaging. The HCPL-0720-060E is supplied in Tube format. All maintain identical 8-SOIC package dimensions.

Frequently Asked Questions (FAQ)

Q: Can FOD0710 or FOD0710R2 replace the HCPL-0720-060E in my design?

A: FOD0710 and FOD0710R2 are electrically compatible but operate at 12.5Mbps instead of 25MBps. They are suitable only if your application does not require the full 25MBps bandwidth. All other parameters—isolation voltage, channel count, output topology, package, and supply voltage—are compatible.

Q: What is the difference between FOD0720 and FOD0720R2?

A: Both parts are electrically identical. FOD0720 is supplied in Bulk packaging, while FOD0720R2 is supplied in Tape & Reel format. Selection depends on assembly process requirements.

Q: Why does ACSL-7210-06RE have two channels when the HCPL-0720-060E has one?

A: ACSL-7210-06RE is a different product category designed for applications requiring dual isolated channels. It is not a direct substitute but may be considered for designs where multiple isolated signals are needed within a single package footprint.

Q: Are all substitute parts ROHS3 compliant?

A: FOD0720, FOD0720R2, FOD0721, FOD0721R2, and FOD0710R2 are ROHS3 compliant. FOD0710 does not list RoHS status in the provided specifications. ACSL-7210-06RE is ROHS3 compliant.

Q: What is the impact of higher CMTI (20kV/µs vs. 10kV/µs) on my circuit?

A: Higher common mode transient immunity provides better noise rejection during rapid voltage transitions on the isolated side. FOD series parts with 20kV/µs CMTI offer superior performance in electrically noisy environments compared to the HCPL-0720-060E at 10kV/µs.

Q: Can I use FOD0721 instead of FOD0720 in my design?

A: Yes. Both are functionally equivalent with identical electrical specifications. FOD0721 is manufactured by onsemi while FOD0720 is from Fairchild. Selection may depend on supply chain availability or preferred supplier relationships.

Q: Does the extended temperature range of FOD series (-40°C to 100°C) affect circuit design?

A: The extended range provides additional operational margin but does not require circuit modifications. If your application operates within the HCPL-0720-060E range (-40°C to 85°C), FOD series parts will function identically.
