HCPL-0661#500 Equivalent & Substitute Parts

Part Overview

The HCPL-0661#500 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 2-channel device provides 3750Vrms isolation with open collector, Schottky clamped outputs and supports data rates up to 10MBd. The part is currently active in production and widely used in industrial control, power management, and communication interface circuits where galvanic isolation is required. Substitute parts are identified to address packaging preferences, compliance requirements, and inventory availability while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-0661#500 are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is functional equivalence across the following key parameters:

• Isolation Voltage: 3750Vrms (mandatory match)
• Number of Channels: 2 (mandatory match)
• Output Configuration: Open Collector, Schottky Clamped (mandatory match)
• Data Rate: 10MBd (mandatory match)
• Package Type: 8-SOIC (0.154", 3.90mm Width) (mandatory match)
• Voltage Supply Range: 4.5V ~ 5.5V (mandatory match)
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)

The HCPL-0661-500E qualifies as a direct substitute because it maintains identical electrical specifications and mechanical form factor. The difference lies in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and compliance status, which do not affect circuit-level functionality.

Parameter Comparison

Engineering Selection Recommendations

HCPL-0661-500E is the direct substitute for HCPL-0661#500. Selection between these parts should be based on the following factors:

Compliance Status: The HCPL-0661-500E carries RoHS3 compliance, whereas the HCPL-0661#500 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, HCPL-0661-500E is the appropriate choice.

Packaging Format: HCPL-0661#500 is supplied in Tape & Reel (TR) format, while HCPL-0661-500E is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly line requirements and minimum order quantities.

Inventory Availability: Both parts are in active production. HCPL-0661-500E maintains higher stock levels (29110 Pcs) compared to HCPL-0661#500 (1012 Pcs), which may influence lead time and procurement strategy.

Electrical Equivalence: Both parts are electrically identical across all specified parameters and are pin-compatible in 8-SOIC package configurations. No circuit redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can HCPL-0661-500E be used as a direct replacement for HCPL-0661#500 in existing designs?

A: Yes. Both parts share identical electrical specifications, pin configuration, and package dimensions (8-SOIC, 0.154" width). No circuit modifications are necessary for substitution.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is a continuous reel format suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for lower-volume orders and mixed component picking. Both formats contain the same component; the difference is in delivery and handling format.

Q: Does RoHS3 compliance affect circuit performance?

A: No. RoHS3 compliance indicates the absence of restricted substances (lead, cadmium, mercury, etc.) in the component manufacturing process. Electrical and thermal performance remain unchanged.

Q: Are the isolation voltage and CMTI specifications identical between both parts?

A: Yes. Both HCPL-0661#500 and HCPL-0661-500E provide 3750Vrms isolation voltage and 15kV/µs common mode transient immunity. These critical parameters are matched across both part numbers.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C. This range applies to all electrical specifications and performance guarantees.

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

A: Yes, provided the PCB footprint accommodates the 8-SOIC (0.154", 3.90mm Width) package. Both parts use identical pin assignments and mechanical dimensions.
