Engineering Selection Recommendations

The HCPL-4701-560E and HCPL-4701-500E are direct functional equivalents to the HCPL-4701-560. Both substitute parts are currently active products from Broadcom Limited and maintain identical electrical and mechanical specifications across all critical parameters.

The HCPL-4701-560E is the primary direct substitute, offering identical specifications with Tape & Reel packaging and ROHS3 compliance. The HCPL-4701-500E provides an alternative active source with equivalent parametric performance and identical packaging configuration.

Both substitute parts are ROHS3 compliant, whereas the original HCPL-4701-560 is RoHS non-compliant. This compliance improvement may be required for applications subject to regulatory restrictions on hazardous substances. All three parts maintain REACH Unaffected status and identical Moisture Sensitivity Level classification.

Frequently Asked Questions (FAQ)

Q: Can HCPL-4701-560E and HCPL-4701-500E be used interchangeably with HCPL-4701-560?

A: Yes. Both substitute parts maintain identical electrical specifications including isolation voltage (3750Vrms), current transfer ratio (600% to 8000% @ 500µA), output characteristics (18V max, 60mA per channel), and timing parameters (3µs turn-on, 34µs turn-off). Package configuration, pin assignment, and mounting type are identical across all three parts.

Q: What is the difference between HCPL-4701-560E and HCPL-4701-500E?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The primary difference is inventory availability and product sourcing. Both are active products from Broadcom Limited supplied in Tape & Reel packaging with ROHS3 compliance.

Q: Does the packaging format affect substitution compatibility?

A: The HCPL-4701-560 is supplied in bulk packaging, while HCPL-4701-560E and HCPL-4701-500E are supplied in Tape & Reel format. This affects handling and assembly processes but does not alter electrical or mechanical compatibility. The component itself remains identical.

Q: Are there compliance differences between these parts?

A: The original HCPL-4701-560 is RoHS non-compliant. Both substitute parts (HCPL-4701-560E and HCPL-4701-500E) are ROHS3 compliant. All three parts maintain REACH Unaffected status. Applications subject to RoHS requirements must use the substitute parts.

Q: What is the operating temperature range for these optoisolators?

A: All three parts operate across 0°C to 70°C. This specification is identical across HCPL-4701-560, HCPL-4701-560E, and HCPL-4701-500E.
