Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-4506#360 is determined by strict equivalence across the following critical parameters:

Manufacturer: Broadcom Limited (same manufacturer ensures design consistency)
Number of Channels: 1 (functional requirement)
Voltage - Isolation: 3750Vrms (isolation specification)
Common Mode Transient Immunity (Min): 15kV/µs (signal integrity requirement)
Input Type: DC (input signal specification)
Output Type: Open Collector, Schottky Clamped (output configuration)
Current - Output / Channel: 15 mA (load driving capability)
Propagation Delay tpLH / tpHL (Max): 550ns, 400ns (timing specification)
Voltage - Forward (Vf) (Typ): 1.5V (LED forward voltage)
Current - DC Forward (If) (Max): 25mA (LED current rating)
Voltage - Supply: 4.5V ~ 30V (power supply range)
Operating Temperature: -40°C ~ 100°C (thermal operating range)
Package / Case: 8-SMD, Gull Wing (physical and electrical interface)

The substitute part HCPL-4506-360E meets all these criteria and is manufactured by the same supplier, ensuring pin-compatible and functionally equivalent operation.

Engineering Selection Recommendations

Both HCPL-4506#360 and HCPL-4506-360E are functionally equivalent optoisolators with identical electrical and mechanical specifications. The primary distinction lies in regulatory compliance status.

HCPL-4506#360 is RoHS non-compliant, while HCPL-4506-360E is ROHS3 compliant. For applications subject to RoHS3 regulations or requiring compliance documentation, HCPL-4506-360E is the appropriate selection. Both parts maintain REACH Unaffected status and carry the same ECCN and HTSUS classifications.

Both components are Active products with unlimited moisture sensitivity level (MSL 1), ensuring consistent long-term availability and handling requirements. Selection between these parts should be based on the specific regulatory requirements of the target application and regional market.

Frequently Asked Questions (FAQ)

Q: Are HCPL-4506#360 and HCPL-4506-360E pin-compatible?

A: Yes. Both parts use the 8-SMD Gull Wing package configuration with identical pinout and electrical interface specifications.

Q: What is the primary difference between these two parts?

A: The HCPL-4506-360E is ROHS3 compliant, while the HCPL-4506#360 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Can I substitute HCPL-4506-360E for HCPL-4506#360 in existing designs?
