Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-7723-020 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 5000Vrms
• Common mode transient immunity: 10kV/µs minimum
• Output configuration: Push-pull, totem pole topology
• Data rate capability: 50MBd
• Single channel configuration
• Package type: 8-DIP through-hole
• Supply voltage range: 4.5V to 5.5V
• Operating temperature range: -40°C to 85°C

The HCPL-7723-020E meets all these criteria and is identified as a direct substitute based on identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-7723-020E is the direct substitute for the HCPL-7723-020. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction is product status: the original part is discontinued, while the HCPL-7723-020E remains in active production with improved compliance status. The HCPL-7723-020E carries ROHS3 compliance, whereas the original part is RoHS non-compliant. For new designs and ongoing system support, the HCPL-7723-020E is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-7723-020E be used as a direct replacement for the HCPL-7723-020?

A: Yes. The HCPL-7723-020E is electrically and mechanically identical to the HCPL-7723-020. All electrical parameters, including isolation voltage, CMTI, data rate, propagation delay, and output current, are equivalent. The 8-DIP package dimensions and pin configuration are identical, enabling direct substitution without circuit modification.

Q: What is the difference between the HCPL-7723-020 and HCPL-7723-020E?

A: The parts are functionally equivalent. The HCPL-7723-020E is the active production variant with ROHS3 compliance. The original HCPL-7723-020 is discontinued and RoHS non-compliant. Packaging differs: the HCPL-7723-020E is supplied in tube packaging, while the original part packaging is unspecified.

Q: Are there any timing or performance differences between these parts?

A: No. Propagation delay (22ns maximum for both rising and falling edges), rise time (8ns typical), and fall time (6ns typical) are identical across both parts. Data rate capability remains 50MBd for both variants.

Q: What supply voltage range is required for these optoisolators?

A: Both the HCPL-7723-020 and HCPL-7723-020E operate with a supply voltage range of 4.5V to 5.5V. This range must be maintained for proper device operation.

Q: Is the 8-DIP package suitable for surface mount or through-hole assembly?

A: The 8-DIP package is designed for through-hole mounting only. The package dimensions are 0.300 inches (7.62mm) in width, standard for DIP packages. Surface mount alternatives would require a different package type not covered by this substitution.
