Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-2601#520 is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 5000Vrms
• Single channel configuration
• Open collector output with Schottky clamping
• Data rate: 10MBd minimum
• Common mode transient immunity: 10kV/µs minimum
• Output current capability: 50 mA per channel
• Propagation delay specifications: 100ns maximum (tpLH and tpHL)
• Supply voltage range: 4.5V to 5.5V
• Operating temperature range: -40°C to 85°C
• Package type: 8-DIP Gull Wing surface mount

The HCPL-2601-520E qualifies as a direct substitute based on identical electrical specifications and package configuration. Additional cross-reference parts (FOD260LSD, FOD260LS) are listed in the substitute chain but require independent verification against the above parameters.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2601-520E is the primary substitute for the discontinued HCPL-2601#520. Both components are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical parameters.

The HCPL-2601-520E offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Additionally, the HCPL-2601-520E carries ROHS3 compliance, whereas the original HCPL-2601#520 is RoHS non-compliant. This compliance improvement may be relevant for applications subject to RoHS regulatory requirements.

Both components maintain identical isolation voltage, data rate, propagation delay, output current capability, and package configuration. No circuit redesign is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-2601-520E be used as a direct replacement for the HCPL-2601#520?

A: Yes. The HCPL-2601-520E is electrically and mechanically equivalent to the HCPL-2601#520 across all specified parameters, including isolation voltage (5000Vrms), data rate (10MBd), output current (50 mA), propagation delay (100ns max), and package type (8-DIP Gull Wing). No circuit modifications are necessary.

Q: What is the primary reason to substitute the HCPL-2601#520?

A: The HCPL-2601#520 is discontinued at DiGi Electronics. The HCPL-2601-520E provides equivalent functionality with active product status and improved RoHS3 compliance.

Q: Are there differences in package handling or moisture sensitivity between these parts?

A: No. Both components share identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What parameters must remain constant when selecting a substitute optoisolator?

A: Critical parameters for substitution include isolation voltage (5000Vrms), number of channels (1), output type (Open Collector, Schottky Clamped), data rate (10MBd), common mode transient immunity (10kV/µs), output current per channel (50 mA), propagation delay specifications (100ns maximum), supply voltage range (4.5V to 5.5V), operating temperature range (-40°C to 85°C), and package configuration (8-DIP Gull Wing).

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance status reflects manufacturing process and material composition but does not alter electrical performance or functional characteristics. The ROHS3 compliance of the HCPL-2601-520E may be required for applications subject to RoHS regulatory frameworks.
