HCPL-263N#320 Equivalent & Substitute Parts

Part Overview

The HCPL-263N#320 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 2-channel device provides 5000Vrms isolation with open collector, Schottky clamped outputs and supports data rates up to 10MBd. The part is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing system support and new designs requiring this isolation topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-263N#320 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 2
• Voltage - Isolation: 5000Vrms
• Common Mode Transient Immunity (Min): 15kV/µs
• Output Type: Open Collector, Schottky Clamped
• Current - Output / Channel: 50 mA
• Data Rate: 10MBd
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 8-SMD, Gull Wing

The HCPL-263N-320E meets all these parameters identically, establishing it as a direct functional equivalent. Both parts share the same base product number (HCPL-263) and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-263N-320E is the direct substitute for the discontinued HCPL-263N#320. Both parts are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical isolation, timing, and output parameters.

The primary distinction between the two parts is product status and regulatory compliance. The HCPL-263N#320 is discontinued and RoHS non-compliant, while the HCPL-263N-320E is currently active and ROHS3 compliant. For new designs or systems requiring ongoing component availability, the HCPL-263N-320E is the appropriate selection. Both parts maintain identical performance characteristics for 5000Vrms isolation, 2-channel configuration, 10MBd data rate, and open collector output topology.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-263N-320E directly replace the HCPL-263N#320 in existing designs?

A: Yes. The HCPL-263N-320E is electrically and mechanically identical to the HCPL-263N#320 across all specified parameters. Pin configuration, package footprint (8-SMD Gull Wing), isolation voltage, channel count, output type, and timing characteristics are equivalent.

Q: What is the difference between HCPL-263N#320 and HCPL-263N-320E?
