Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-2400#500 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 1
• Voltage - Isolation: 3750Vrms
• Common Mode Transient Immunity (Min): 1kV/µs
• Output Type: Tri-State
• Data Rate: 40MBd
• Current - Output / Channel: 25 mA
• Propagation Delay tpLH / tpHL (Max): 55ns, 55ns
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 8-SMD, Gull Wing

The HCPL-2400-500E meets all these parameters and is classified as a direct manufacturer substitute. Both parts share the same base product number (HCPL-2400) and are functionally identical in electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2400-500E is the direct substitute for the HCPL-2400#500. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility.

The primary distinction between these parts is product status and regulatory compliance. The HCPL-2400#500 is discontinued, while the HCPL-2400-500E is active and available. Additionally, the HCPL-2400-500E carries ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

For new designs and production, the HCPL-2400-500E is the appropriate selection. For legacy system maintenance where the original part specification must be preserved, the HCPL-2400-500E provides full electrical and mechanical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-2400-500E be used as a direct replacement for the HCPL-2400#500?

A: Yes. The HCPL-2400-500E is electrically and mechanically identical to the HCPL-2400#500. All critical parameters—isolation voltage, data rate, propagation delay, output current, and package configuration—are equivalent. No circuit modifications are required.

Q: What is the difference between HCPL-2400#500 and HCPL-2400-500E?

A: The primary differences are product status and compliance. The HCPL-2400#500 is discontinued and RoHS non-compliant. The HCPL-2400-500E is active and ROHS3 compliant. Functionally and electrically, they are identical.

Q: Are there any packaging differences between these parts?

A: No. Both parts use the same 8-SMD Gull Wing package configuration. The HCPL-2400-500E is available in Cut Tape (CT) and Digi-Reel packaging options, providing flexibility for different procurement volumes.

Q: What parameters determine substitution eligibility for optoisolators in this category?

A: For the HCPL-2400 series, substitution is determined by matching: isolation voltage (3750Vrms), number of channels (1), output type (tri-state), data rate (40MBd), common mode transient immunity (1kV/µs), output current (25 mA), propagation delay (55ns max), supply voltage range (4.75V–5.25V), operating temperature range (−40°C to 85°C), and package type (8-SMD Gull Wing).

Q: Is the HCPL-2400-500E suitable for new production designs?

A: Yes. The HCPL-2400-500E is the active product and is recommended for all new designs. It provides the same performance as the discontinued HCPL-2400#500 with improved regulatory compliance (ROHS3).
