HCPL-2730#020 Equivalent & Substitute Parts

Part Overview

The HCPL-2730#020 is a 2-channel optoisolator with Darlington output, rated for 5000Vrms isolation voltage. This component is designed for applications requiring high-voltage isolation between input and output circuits with DC input control and Darlington output switching capability. The main part number is currently discontinued at DiGi Electronics, making substitute part identification essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the HCPL-2730#020 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 2
• Voltage - Isolation: 5000Vrms
• Current Transfer Ratio range: 300% (Min) to 2600% (Max) @ 1.6mA
• Input Type: DC
• Output Type: Darlington
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Output electrical characteristics: 7V max, 60mA per channel, 100mV Vce saturation

The HCPL-2730-020E meets all these criteria and is therefore a direct functional equivalent. Packaging format differences (Tube vs. standard packaging) do not affect electrical compatibility or pin configuration.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2730-020E is the direct substitute for HCPL-2730#020. Both parts share identical electrical specifications and pin configurations. The primary distinction is product status: HCPL-2730#020 is discontinued, while HCPL-2730-020E is active and available in production quantities.

For new designs or ongoing production requiring compliance with current environmental standards, HCPL-2730-020E is the appropriate selection due to its ROHS3 compliance status. The packaging format difference (Tube) does not affect electrical performance or circuit integration.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2730-020E be used as a direct replacement for HCPL-2730#020?

A: Yes. Both parts are manufactured by Broadcom Limited and share identical electrical specifications, pin configurations, and package dimensions (8-DIP). No circuit modifications are required.

Q: What is the difference between HCPL-2730#020 and HCPL-2730-020E?

A: The primary differences are product status and RoHS compliance. HCPL-2730#020 is discontinued and RoHS non-compliant. HCPL-2730-020E is active and ROHS3 compliant. Electrical performance is identical.

Q: Does the Tube packaging of HCPL-2730-020E affect compatibility?

A: No. Packaging format (Tube vs. standard) is a supply and handling specification only. It does not affect the electrical characteristics, pin configuration, or functional performance of the component.

Q: Are the isolation voltage ratings identical?

A: Yes. Both parts provide 5000Vrms isolation voltage with identical current transfer ratio specifications (300% minimum to 2600% maximum @ 1.6mA).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: number of channels (2), isolation voltage (5000Vrms), current transfer ratio range, input type (DC), output type (Darlington), package type (8-DIP), and output electrical characteristics (7V max, 60mA per channel, 100mV Vce saturation).
