Engineering Selection Recommendations
Primary Recommendation: HCPL-4502-060E
HCPL-4502-060E is the direct manufacturer substitute with identical electrical specifications and packaging. This part is currently active in production and offers ROHS3 compliance, addressing regulatory requirements that the original HCPL-4502#060 does not meet. Inventory availability is 1060 units.
Secondary Recommendations: HCPL-4502-000E and HCPL-4503-060E
Both HCPL-4502-000E and HCPL-4503-060E are parametric equivalents with identical electrical performance and ROHS3 compliance. HCPL-4502-000E provides 1468 units in stock, while HCPL-4503-060E provides 5800 units. These parts are suitable for applications where RoHS compliance is required.
Alternative: HCPL-4503-000E
HCPL-4503-000E differs in turn-on/turn-off timing specifications (1µs, 1µs Max versus 200ns, 600ns Typ). This part is suitable only for applications where slower switching response is acceptable. It offers the highest inventory availability at 15885 units and ROHS3 compliance.
Non-Compliant Alternatives: HCPL-4503 and HCPL-4502
HCPL-4503 and HCPL-4502 are parametric equivalents with identical electrical specifications but RoHS non-compliant status. These parts are suitable only for applications without RoHS compliance requirements. Both are active in production with 5800 units available.
Frequently Asked Questions (FAQ)
Q: Can HCPL-4503-000E be used as a direct replacement for HCPL-4502#060?
A: HCPL-4503-000E is a parametric equivalent with one critical difference: turn-on/turn-off timing is specified as 1µs maximum versus 200ns/600ns typical for the original part. This slower response time may affect circuit performance in timing-sensitive applications. Electrical isolation, current transfer ratio, output voltage, and current ratings are identical.
Q: What is the difference between HCPL-4502-060E and HCPL-4502-000E?
A: Both parts are parametrically identical with identical electrical specifications, operating temperature range, and packaging. The primary difference is RoHS compliance status (both are ROHS3 compliant) and inventory availability. HCPL-4502-060E has 1060 units in stock, while HCPL-4502-000E has 1468 units.
Q: Why should I choose an ROHS3 compliant part over the original HCPL-4502#060?
A: The original HCPL-4502#060 is RoHS non-compliant and discontinued. ROHS3 compliant alternatives such as HCPL-4502-060E, HCPL-4502-000E, HCPL-4503-000E, and HCPL-4503-060E meet current regulatory requirements for hazardous substance restrictions and are actively produced by Broadcom Limited.
Q: Are all substitute parts available in the same 8-DIP package?
A: Yes. All substitute parts listed are packaged in 8-DIP (0.300", 7.62mm) through-hole format, identical to the original HCPL-4502#060. Direct PCB substitution is possible without layout modifications.
Q: What is the inventory status of substitute parts?
A: All substitute parts are currently in active production status with available inventory: HCPL-4502-060E (1060 units), HCPL-4502-000E (1468 units), HCPL-4503 (5380 units), HCPL-4503-000E (15885 units), HCPL-4503-060E (5800 units), and HCPL-4502 (5800 units).
Q: Can I use HCPL-4503 or HCPL-4502 in new designs?
A: HCPL-4503 and HCPL-4502 are parametrically equivalent but RoHS non-compliant. These parts are suitable only for applications without RoHS compliance requirements or legacy systems. For new designs, ROHS3 compliant alternatives are recommended.
