Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-0701#500 are classified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Number of Channels: 1
• Output Type: Darlington with Base or Transistor with Base
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Current Transfer Ratio (Min): 500% @ 1.6mA
• Current Transfer Ratio (Max): 2600% @ 1.6mA
• Voltage - Output (Max): 18V
• Current - Output / Channel: 60mA
• Operating Temperature: -40°C ~ 85°C
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Isolation Voltage Consideration: The main part specifies 3750Vrms isolation. Substitute parts with equal or higher isolation voltage (3750Vrms or greater) maintain or exceed the isolation specification. Parts with lower isolation voltage (2500Vrms) represent a reduced isolation capability and are listed for reference only.

Packaging Variation: Substitute parts may differ in packaging format (Tape & Reel, Cut Tape, or Tube) without affecting electrical performance or mechanical fit in the application.

Parameter Comparison

Engineering Selection Recommendations

Direct Broadcom Substitutes (Identical Electrical Performance):

HCPL-0701-000E, HCPL-0701, and HCPL-0701-500E are direct substitutes from Broadcom Limited with identical electrical specifications to the HCPL-0701#500. These parts maintain 3750Vrms isolation voltage, matching current transfer ratios, and identical switching characteristics. The primary differences are packaging format (Tube or Cut Tape) and RoHS compliance status. HCPL-0701-000E and HCPL-0701-500E are ROHS3 compliant, while HCPL-0701#500 and HCPL-0701 are RoHS non-compliant. Selection among these should be based on packaging requirements and compliance mandates for the end application.

onsemi HCPL0701 (Reduced Isolation Voltage):

The onsemi HCPL0701 maintains electrical performance in current transfer ratio, output voltage, and output current specifications. However, this part specifies 2500Vrms isolation voltage compared to the 3750Vrms of the main part. This represents a 1250Vrms reduction in isolation capability. Switching time characteristics differ slightly (300ns turn-on versus 200ns, and 1.6µs turn-off versus 2µs). This part is suitable only for applications where the lower isolation voltage is acceptable.

Vishay SFH6319T (Enhanced Isolation Voltage):

The SFH6319T from Vishay Semiconductor Opto Division provides 4000Vrms isolation voltage, exceeding the 3750Vrms specification of the main part. Current transfer ratios and output specifications remain equivalent. The output type is specified as Transistor with Base rather than Darlington with Base, and switching characteristics differ (600ns turn-on versus 200ns, and 1.5µs turn-off versus 2µs). Operating temperature range extends to -55°C ~ 100°C compared to -40°C ~ 85°C. This part is suitable for applications requiring higher isolation voltage or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can HCPL-0701-000E be used as a direct replacement for HCPL-0701#500?

A: Yes. Both parts are manufactured by Broadcom Limited with identical electrical specifications including 3750Vrms isolation voltage, 500% to 2600% current transfer ratio, 18V maximum output voltage, and 60mA output current. The primary difference is packaging format (Tube versus Tape & Reel) and RoHS compliance status. Mechanical fit in the 8-SOIC footprint is identical.

Q: What is the significance of the packaging differences (Tape & Reel, Cut Tape, Tube)?

A: Packaging format affects handling, storage, and automated assembly processes but does not impact electrical performance or mechanical compatibility. Tape & Reel and Cut Tape formats are optimized for high-volume automated assembly. Tube packaging is suitable for lower-volume applications or manual assembly. All formats use the same 8-SOIC package footprint.

Q: Why does the onsemi HCPL0701 have lower isolation voltage?

A: The onsemi HCPL0701 is specified at 2500Vrms isolation compared to 3750Vrms for the Broadcom parts. This is a design difference between manufacturers. Applications requiring 3750Vrms or higher isolation should not use this part.

Q: Is the Vishay SFH6319T a suitable substitute?

A: The SFH6319T maintains equivalent current transfer ratio and output specifications with 4000Vrms isolation voltage, which exceeds the 3750Vrms requirement. However, switching times are slower (600ns turn-on versus 200ns) and the output type is Transistor with Base rather than Darlington with Base. Suitability depends on whether the application can tolerate these timing differences and the alternative output configuration.

Q: What does RoHS compliance mean for component selection?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. If your application or end market requires RoHS compliance, select HCPL-0701-000E or HCPL-0701-500E. If RoHS compliance is not required, all listed parts are functionally equivalent.

Q: Are all substitute parts pin-compatible?

A: All listed substitute parts use the 8-SOIC package with identical pin configuration and footprint. Pin compatibility is maintained across all substitutes.

Q: What is the difference between Darlington and Transistor output types?

A: Both output types include a base connection. Darlington output provides higher current gain, while Transistor output provides different gain characteristics. The SFH6319T uses Transistor output instead of Darlington. Verify that your circuit design accommodates the output type before substitution.
