Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-2411#500 is determined by the following critical parameters:

• Isolation Voltage: Substitute parts must meet or exceed 2500Vrms isolation rating
• Output Configuration: Tri-state output type is required for functional compatibility
• Data Rate: 40MBd minimum performance specification
• Common Mode Transient Immunity: 1kV/µs minimum CMTI rating
• Package Type: 8-SMD, Gull Wing form factor for PCB compatibility
• Supply Voltage Range: 4.75V ~ 5.25V operation
• Number of Channels: Single-channel configuration

The HCPL-2400-500E meets all substitution criteria, offering enhanced isolation voltage (3750Vrms) while maintaining identical functional specifications for data rate, output type, CMTI, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2400-500E is the direct substitute for the HCPL-2411#500. Selection of this alternative is supported by the following factors:

Product Availability: The HCPL-2400-500E maintains active product status with 3200 units in stock, compared to the discontinued HCPL-2411#500.

Functional Equivalence: All critical electrical parameters are identical, including data rate (40MBd), output type (tri-state), CMTI (1kV/µs), and supply voltage range (4.75V ~ 5.25V). Pin configuration and package form factor (8-SMD, Gull Wing) are identical, enabling direct PCB substitution without layout modifications.

Enhanced Specifications: The HCPL-2400-500E provides higher isolation voltage (3750Vrms versus 2500Vrms) and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), offering improved performance margins for demanding applications.

Regulatory Compliance: The HCPL-2400-500E is ROHS3 compliant, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and identical moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-2400-500E be used as a direct replacement for the HCPL-2411#500?

A: Yes. The HCPL-2400-500E is functionally equivalent with identical pin configuration, package type (8-SMD, Gull Wing), and all critical electrical parameters. No circuit modifications or PCB redesign are required.

Q: What are the key differences between these parts?

A: The primary differences are isolation voltage (3750Vrms versus 2500Vrms), operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), and RoHS compliance status (ROHS3 Compliant versus non-compliant). The substitute part offers enhanced specifications in all cases.

Q: Are the propagation delays and timing characteristics identical?

A: Yes. Both parts specify identical propagation delay (55ns maximum for both tpLH and tpHL) and rise/fall times (20ns typical rise, 10ns typical fall).

Q: Does the higher isolation voltage of the HCPL-2400-500E affect circuit design?

A: No. The higher isolation voltage is a performance enhancement that does not require circuit modifications. The part operates within the same supply voltage range (4.75V ~ 5.25V) and maintains identical output current (25 mA per channel).

Q: What is the impact of the extended operating temperature range?

A: The HCPL-2400-500E supports operation from -40°C to 85°C, compared to 0°C to 70°C for the original part. This extended range provides greater flexibility for applications in temperature-sensitive environments without requiring design changes.

Q: Are both parts available in the same packaging options?

A: Both parts use identical 8-SMD, Gull Wing surface mount packages. The HCPL-2400-500E is available in Cut Tape (CT) and Digi-Reel® packaging formats.
