Engineering Selection Recommendations

HCPL-060L Series (HCPL-060L-500E, HCPL-060L-560E): These Broadcom Limited optoisolators provide higher data rate capability at 15MBd compared to the HCPL0611R2 at 10Mbps. Common mode transient immunity is reduced to 10kV/µs. Both parts maintain ROHS3 compliance and the same 8-SOIC package footprint. The HCPL-060L-500E is available in Cut Tape & Digi-Reel packaging, while HCPL-060L-560E is supplied in Tape & Reel format matching the original part's packaging type. Selection between these variants depends on procurement and assembly line requirements.

HCPL-061 Series (HCPL-061N-000E, HCPL-061N-500E, HCPL-061N-560E, HCPL-061A-000E, HCPL-061A-500E): These Broadcom Limited optoisolators maintain the 10MBd data rate specification matching the HCPL0611R2. Common mode transient immunity is reduced to 1kV/µs, and propagation delay increases to 100ns maximum. All variants carry ROHS3 compliance and the 8-SOIC package specification. The HCPL-061N series variants differ only in packaging format: Tube (HCPL-061N-000E), Cut Tape & Digi-Reel (HCPL-061N-500E), and Tape & Reel (HCPL-061N-560E). The HCPL-061A series provides identical electrical specifications with alternative packaging options: Tube (HCPL-061A-000E) and Cut Tape & Digi-Reel (HCPL-061A-500E).

All substitute parts are active in production status with REACH Unaffected designation and EAR99 export classification, matching the regulatory profile of the main part.

Frequently Asked Questions (FAQ)

Q: Can HCPL-060L series parts directly replace HCPL0611R2 in all applications? A: HCPL-060L series parts maintain isolation voltage, channel count, output current, and package compatibility. However, common mode transient immunity is reduced from 15kV/µs to 10kV/µs. Applications requiring the full 15kV/µs CMTI specification must retain the HCPL0611R2 or equivalent onsemi part.

Q: What is the difference between HCPL-061N and HCPL-061A variants? A: HCPL-061N and HCPL-061A variants are electrically identical, with differences limited to packaging format options. Both provide 10MBd data rate and 1kV/µs CMTI. Selection is based on procurement requirements: Tube, Cut Tape & Digi-Reel, or Tape & Reel formats.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the environmental compliance of the HCPL0611R2.

Q: Does the Schottky Clamped output configuration affect circuit compatibility? A: The HCPL0611R2 features open collector output, while all Broadcom Limited substitutes feature open collector with Schottky clamped configuration. Schottky clamping provides faster switching transitions and reduced parasitic effects. This enhancement is compatible with standard open collector interface designs.

Q: Which substitute part offers the closest performance match to HCPL0611R2? A: HCPL-060L series parts provide the closest performance match with 75ns propagation delay and 15MBd data rate capability. HCPL-061 series parts maintain 10MBd data rate but with increased propagation delay to 100ns and reduced CMTI to 1kV/µs.

Q: Can packaging format be mixed within a single design? A: Packaging format selection (Tube, Cut Tape & Digi-Reel, Tape & Reel) is determined by assembly line equipment and procurement processes. Electrical and mechanical specifications remain identical across packaging variants of the same part number base.

Q: What is the inventory status of substitute parts? A: Inventory availability varies by part number and packaging format. HCPL-060L-500E shows 24,075 units in stock. HCPL-061A-500E shows 20,300 units. Specific availability should be confirmed through component supplier channels.
