HCPL-070A#560 Equivalent & Substitute Parts

Part Overview

The HCPL-070A#560 is an optoisolator with Darlington output and base connection, manufactured by Broadcom Limited. This component provides 3750Vrms isolation in a single-channel configuration with 8-SOIC surface mount packaging. The part is currently active in production with 847 units in stock.

Equivalent and substitute parts are identified when design requirements permit relaxation of specific electrical parameters while maintaining functional compatibility within the application circuit. Substitute parts may differ in isolation voltage, current transfer ratio specifications, operating temperature range, packaging format, or compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the HCPL-070A#560 are classified based on electrical and mechanical compatibility criteria:

Parametric Equivalent Classification: Parts that maintain identical or equivalent electrical specifications across isolation voltage, current transfer ratio, output type, and package form factor. These parts are direct functional replacements with no circuit redesign required.

Manufacturer Recommended Classification: Parts from alternative manufacturers that provide similar functional performance but may differ in one or more of the following parameters: isolation voltage rating, current transfer ratio range, operating temperature range, or compliance certifications. These parts require design review to confirm suitability for the specific application.

Key Parameters Determining Substitution Eligibility:

• Isolation voltage (3750Vrms or higher preferred)
• Current transfer ratio range (600% minimum at specified test current)
• Output type (Darlington with Base configuration)
• Package form factor (8-SOIC surface mount)
• Maximum output current (60mA minimum)
• Maximum output voltage (18V minimum)

Parameter Comparison

Engineering Selection Recommendations

HCPL-070A-500E (Broadcom Limited): This part is a parametric equivalent to the HCPL-070A#560, maintaining identical electrical specifications including 3750Vrms isolation voltage and 600-8000% current transfer ratio range. The primary distinction is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and RoHS3 compliance status. Selection of this part is appropriate when RoHS3 compliance is required for the end application or when Cut Tape packaging is preferred for manufacturing processes. Electrical performance and circuit compatibility are equivalent to the main part.

HCPL0701 (onsemi): This part is a manufacturer-recommended alternative from onsemi. Key differences include reduced isolation voltage (2500Vrms versus 3750Vrms), lower current transfer ratio maximum (2600% versus 8000%), higher maximum forward current (20mA versus 5mA), and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). This part is suitable for applications where the lower isolation voltage is acceptable and the extended temperature range provides operational advantage. RoHS3 compliance is available. Circuit redesign review is required to confirm compatibility with the reduced isolation voltage and current transfer ratio specifications.

Frequently Asked Questions (FAQ)

Q: Can HCPL-070A-500E be used as a direct replacement for HCPL-070A#560?

A: Yes. Both parts are manufactured by Broadcom Limited and maintain identical electrical specifications including isolation voltage, current transfer ratio, output type, and maximum ratings. The parts differ only in packaging format and RoHS compliance status. No circuit modifications are required for substitution.

Q: What are the limitations of using HCPL0701 as a substitute?

A: The HCPL0701 has a lower isolation voltage rating (2500Vrms versus 3750Vrms) and a lower maximum current transfer ratio (2600% versus 8000%). Applications requiring the full 3750Vrms isolation specification or higher current transfer ratio performance must verify that the reduced specifications remain acceptable. The extended operating temperature range (-40°C to 85°C) may provide benefit in temperature-critical applications.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 8-SOIC (0.154", 3.90mm Width) package form factor and are surface mount components. PCB footprint compatibility is maintained across all three parts.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape wound on a reel, suitable for high-volume automated assembly. Cut Tape & Digi-Reel packaging is supplied in shorter tape segments on reels, suitable for lower-volume or mixed-component assembly processes. Electrical performance is identical; packaging selection depends on manufacturing process requirements.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. RoHS3-compliant parts (HCPL-070A-500E and HCPL0701) perform identically to non-compliant parts in circuit operation. Selection based on RoHS status depends on end-product regulatory requirements.

Q: What is the significance of the current transfer ratio test conditions?

A: Current transfer ratio is measured at specific input current levels. HCPL-070A#560 and HCPL-070A-500E are tested at 500µA input current, while HCPL0701 is tested at 1.6mA input current. These different test conditions reflect design differences between manufacturers. Circuit design must account for the actual input current levels used in the application to ensure adequate gain margin.
