HCPL-260L-300 Equivalent & Substitute Parts

Part Overview

The HCPL-260L-300 is a logic output optoisolator manufactured by Broadcom Limited, featuring 3750Vrms isolation voltage, open collector Schottky clamped output, and 15MBd data rate in an 8-DIP gull wing package. This part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-260L-300 is determined by the following critical parameters: single-channel configuration, open collector Schottky clamped output topology, DC input type, 50mA output current capability, surface mount 8-SMD gull wing package, and operating temperature range of -40°C to 85°C.

The HCPL-260L-300E maintains identical electrical and mechanical specifications with the primary distinction being packaging format (tube) and active product status with RoHS3 compliance.

The FOD260LS and FOD260LSD (onsemi) represent functional equivalents with higher isolation voltage (5000Vrms versus 3750Vrms) and superior common mode transient immunity (25kV/µs versus 10kV/µs), while maintaining identical output topology, current rating, package form factor, and operating temperature range. Data rate specification differs (10Mbps versus 15MBd), representing a lower performance tier acceptable for applications not requiring maximum bandwidth.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement with identical electrical performance and packaging, the HCPL-260L-300E is the primary substitute, offering active product status and RoHS3 compliance while maintaining all critical parameters.

For applications where higher isolation voltage and improved common mode transient immunity provide design margin, the FOD260LS and FOD260LSD (onsemi) are functionally equivalent. Both parts maintain identical output topology, current rating, package form factor, and operating temperature range. The FOD260LSD is supplied in tape and reel format, while FOD260LS is supplied in tube format. Both are active products with RoHS3 compliance.

Selection between Broadcom and onsemi alternatives depends on supply chain availability, packaging requirements, and whether the enhanced isolation voltage and CMTI specifications of the onsemi devices provide value for the specific application.

Frequently Asked Questions (FAQ)

Q: Can FOD260LS or FOD260LSD be used as direct replacements for HCPL-260L-300?

A: Yes. Both parts maintain identical output topology (open collector Schottky clamped), single-channel configuration, 50mA output current, 8-SMD gull wing package, and -40°C to 85°C operating temperature. The onsemi devices provide higher isolation voltage (5000Vrms versus 3750Vrms) and superior common mode transient immunity (25kV/µs versus 10kV/µs), making them functionally superior for isolation and noise immunity performance.

Q: What is the difference between FOD260LS and FOD260LSD?

A: Both parts are electrically identical. The primary difference is packaging format: FOD260LS is supplied in tube packaging, while FOD260LSD is supplied in tape and reel format. Selection depends on assembly process requirements and volume.

Q: Does the lower data rate of FOD260 devices (10Mbps versus 15MBd) affect compatibility?

A: The data rate difference reflects the maximum specified bandwidth. For applications operating below 10Mbps, the onsemi devices are fully compatible. Applications requiring data rates between 10Mbps and 15MBd must use the Broadcom HCPL-260L-300E.

Q: Are all substitute parts RoHS compliant?

A: The HCPL-260L-300E, FOD260LS, and FOD260LSD are all RoHS3 compliant. The original HCPL-260L-300 is RoHS non-compliant.

Q: What supply voltage ranges are supported?

A: HCPL-260L-300 and HCPL-260L-300E support 2.7V ~ 3.6V and 4.5V ~ 5.5V. FOD260LS and FOD260LSD support 3V ~ 5.5V. The onsemi devices do not support the 2.7V ~ 3.6V range; applications requiring this lower voltage range must use Broadcom devices.
