HCPL-263L-320 Equivalent & Substitute Parts

Part Overview

The HCPL-263L-320 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed isolation applications requiring 5000Vrms isolation voltage. This 2-channel device features open collector, Schottky clamped outputs with 15MBd data rate capability and 10kV/µs common mode transient immunity. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Substitute Part Grouping Explanation

Substitution of the HCPL-263L-320 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 2 channels (mandatory match)
• Output Configuration: Open Collector, Schottky Clamped (mandatory match)
• Common Mode Transient Immunity: 10kV/µs minimum (mandatory match)
• Data Rate: 15MBd (mandatory match)
• Propagation Delay: 75ns maximum for both tpLH and tpHL (mandatory match)
• Output Current: 50 mA per channel (mandatory match)
• Supply Voltage Range: 2.7V ~ 3.6V and 4.5V ~ 5.5V (mandatory match)
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)
• Package Type: 8-SMD, Gull Wing (mandatory match)

The HCPL-263L-320E qualifies as a direct substitute based on complete parameter equivalence across all specified electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-263L-320E is the direct equivalent substitute for the HCPL-263L-320. Both parts are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the HCPL-263L-320 is discontinued, while the HCPL-263L-320E maintains active production status.

An additional advantage of the HCPL-263L-320E is its ROHS3 compliance, compared to the non-compliant status of the original part. This compliance improvement supports regulatory requirements in applications subject to RoHS directives. Both parts maintain REACH unaffected status and identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-263L-320E be used as a direct replacement for the HCPL-263L-320?

A: Yes. The HCPL-263L-320E is electrically and mechanically identical to the HCPL-263L-320 across all specified parameters, including isolation voltage, channel count, output configuration, data rate, propagation delay, supply voltage range, and operating temperature range. No circuit modifications are required.

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

A: The parts are functionally equivalent. The HCPL-263L-320E is the active production variant with ROHS3 compliance, while the HCPL-263L-320 is discontinued and RoHS non-compliant. Packaging differs only in that the HCPL-263L-320E is supplied in tube format.

Q: Are there any compatibility concerns when substituting the HCPL-263L-320E for the HCPL-263L-320?

A: No compatibility concerns exist. Both parts use identical 8-SMD Gull Wing packaging and share all electrical specifications. PCB footprints and circuit connections remain unchanged.

Q: What certifications apply to the HCPL-263L-320E?

A: The HCPL-263L-320E is ROHS3 compliant and REACH unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Q: Is the HCPL-263L-320E available in the same packaging as the original part?

A: Both parts use 8-SMD Gull Wing package configuration. The HCPL-263L-320E is supplied in tube packaging, while the original part was supplied without specified packaging format.
