HCPL2630 Equivalent & Substitute Parts

Part Overview

The HCPL2630 is a logic output optoisolator manufactured by onsemi, featuring 2.5kV isolation voltage, 2 channels, open collector output, and 10Mbps data rate in an 8-DIP package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across isolation voltage, channel configuration, output type, data rate, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL2630 is determined by the following critical parameters:

• Channel Configuration: Must be 2 channels with 2 inputs on Side 1 and 0 inputs on Side 2
• Package Form Factor: Must be 8-DIP (0.300", 7.62mm) through-hole mounting
• Output Architecture: Must be open collector type
• Supply Voltage Range: Must support 4.5V ~ 5.5V operation
• Operating Temperature Range: Must support -40°C ~ 85°C
• Data Rate: Must support minimum 10Mbps operation
• Input Type: Must be DC

Substitute parts may exceed the original isolation voltage specification (2500Vrms) while maintaining all other functional parameters. Enhanced CMTI performance is acceptable. Variations in propagation delay, rise/fall time, and forward voltage within the same functional class are permissible provided output current capability remains at or above 50 mA per channel.

Engineering Selection Recommendations

Primary Substitute: HCPL2630M (onsemi)

HCPL2630M is the manufacturer-recommended substitute. It maintains onsemi sourcing continuity, offers active product status, and provides enhanced 5000Vrms isolation voltage while preserving all functional parameters of the original HCPL2630. ROHS3 compliance is maintained. This part is the preferred selection for new designs and production transitions.

Alternative Substitutes: HCPL-2630-000E and HCPL-2630-020E (Broadcom Limited)

Both Broadcom parts are active, ROHS3 compliant alternatives. HCPL-2630-000E provides 3750Vrms isolation, while HCPL-2630-020E provides 5000Vrms isolation. Both feature Schottky-clamped open collector outputs and maintain the required 50 mA output current per channel. These parts are suitable where Broadcom sourcing is acceptable.

Not Recommended: HCPL-2630 (Broadcom Limited)

This variant is RoHS non-compliant and does not meet current regulatory requirements for new production applications.

Frequently Asked Questions (FAQ)

Q: Can HCPL2630M directly replace HCPL2630 in existing designs?

A: Yes. HCPL2630M maintains identical pinout, package form factor, channel configuration, output type, and supply voltage range. The enhanced 5000Vrms isolation voltage provides additional margin without affecting circuit operation.

Q: What is the difference between open collector and Schottky-clamped open collector outputs?

A: Both output types are functionally compatible in this application. Schottky clamping in the Broadcom variants provides faster switching transitions and reduced propagation delay variation, beneficial for high-speed applications.

Q: Are Broadcom HCPL-2630 variants pin-compatible with the onsemi HCPL2630?

A: Yes. All listed substitutes maintain identical 8-DIP pinout and functional signal mapping, enabling direct board-level replacement.

Q: Does higher isolation voltage affect circuit performance?

A: No. Higher isolation voltage (5000Vrms vs. 2500Vrms) provides additional safety margin and does not degrade circuit performance. It is a beneficial enhancement for applications requiring higher isolation specifications.

Q: Which substitute should be selected for new production?

A: HCPL2630M is the recommended primary choice due to manufacturer continuity and active product status. Broadcom alternatives (HCPL-2630-000E or HCPL-2630-020E) are acceptable secondary options where Broadcom sourcing is preferred, provided ROHS3 compliance is verified.

Q: Are all substitutes available in the same packaging options?

A: All listed substitutes are supplied in 8-DIP through-hole packages. Verify specific packaging and tape/reel availability with your supplier for production volume requirements.
