HCPL-261A#560 Equivalent & Substitute Parts

Part Overview

The HCPL-261A#560 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. It provides 3750Vrms isolation with open collector Schottky clamped output, supporting data rates up to 10MBd with 1kV/µs common mode transient immunity. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-261A#560 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms
• Output configuration: Open Collector, Schottky Clamped
• Data rate capability: 10MBd minimum
• Common mode transient immunity: 1kV/µs minimum
• Supply voltage range: 4.5V ~ 5.5V
• Package type: 8-SMD, Gull Wing
• Number of channels: 1
• Operating temperature range: -40°C ~ 85°C

The HCPL-261A-560E is a direct functional equivalent from the same manufacturer, differing only in packaging format (Tape & Reel) and product status (Active vs. Discontinued). Additional cross-manufacturer substitutes (ACPL-C61L-560E, ACPL-W61L-560E, HCPL2601SD) meet the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-261A-560E is the primary substitute for the HCPL-261A#560. Both parts are manufactured by Broadcom Limited and are electrically and mechanically identical. The HCPL-261A-560E differs only in packaging format (Tape & Reel) and carries Active product status with ROHS3 compliance, making it suitable for new designs and production environments requiring RoHS certification.

The cross-manufacturer alternatives ACPL-C61L-560E, ACPL-W61L-560E, and HCPL2601SD maintain full electrical and mechanical equivalence and are also Active products with ROHS3 compliance. These parts are appropriate where supply chain flexibility or alternative sourcing is required.

For applications where RoHS non-compliance is acceptable or required by legacy specifications, the HCPL-261A#560 original part number may be sourced through alternative distributors if inventory is available.

Frequently Asked Questions (FAQ)

Q: Can HCPL-261A-560E be used as a direct replacement for HCPL-261A#560?

A: Yes. Both parts are electrically and mechanically identical. The HCPL-261A-560E is supplied in Tape & Reel packaging and carries Active product status. No circuit modifications are required.

Q: What is the difference between HCPL-261A#560 and HCPL-261A-560E?

A: The primary differences are packaging format (bulk vs. Tape & Reel) and product status (Discontinued vs. Active). Electrical specifications and pin configuration are identical.

Q: Are the cross-manufacturer substitutes (ACPL series) compatible?

A: Yes. ACPL-C61L-560E, ACPL-W61L-560E, and HCPL2601SD meet all electrical and mechanical specifications. Pin configuration and package type are identical to the original part.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance status depends on application requirements. HCPL-261A-560E and all cross-manufacturer alternatives are ROHS3 compliant. The original HCPL-261A#560 is RoHS non-compliant. Select based on your product's regulatory requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All substitute parts use the same 8-SMD Gull Wing package and surface mount configuration. No PCB layout modifications are required.

Q: What isolation voltage do these optoisolators provide?

A: All listed parts provide 3750Vrms isolation, suitable for high-voltage digital isolation applications with 1kV/µs common mode transient immunity.
