HCPL-4534 Equivalent & Substitute Parts

Part Overview

The HCPL-4534 is an optoisolator with transistor output, providing 3750Vrms isolation across 2 channels in an 8-DIP through-hole package. This component is designed for applications requiring galvanic isolation between logic and power circuits, with DC input and transistor output configuration. The part is currently in active production status. Substitute parts may be required due to inventory availability, regional sourcing constraints, or specific compliance requirements for end applications.

Substitute Part Grouping Explanation

Substitution for the HCPL-4534 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 3750Vrms (mandatory match)
• Channel Count: 2 channels (mandatory match)
• Output Configuration: Transistor output (mandatory match)
• Input Type: DC (mandatory match)
• Package Type: 8-DIP through-hole (mandatory match)
• Current Transfer Ratio Range: 15% (Min) to 50% (Max) @ 16mA (mandatory match)
• Switching Times: 200ns turn-on, 600ns turn-off (mandatory match)
• Output Specifications: 20V max, 8mA per channel (mandatory match)
• Operating Temperature Range: -55°C to 100°C (mandatory match)

The HCPL-4534-000E meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical and mechanical specifications, with the primary distinction being compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-4534 and HCPL-4534-000E are electrically and mechanically identical. Selection between these parts should be based on compliance requirements:

• HCPL-4534: Use when RoHS non-compliant components are acceptable for the application. Both REACH Unaffected and EAR99 classification apply.

• HCPL-4534-000E: Use when ROHS3 compliance is required. This variant meets the same electrical specifications and operating parameters while satisfying RoHS3 regulatory requirements. REACH Unaffected and EAR99 classification apply.

Both parts carry Moisture Sensitivity Level 1 (Unlimited) and are suitable for through-hole PCB assembly in the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can HCPL-4534-000E be used as a direct replacement for HCPL-4534?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is RoHS compliance status. Direct pin-for-pin substitution is supported in 8-DIP through-hole applications.

Q: What determines if a part can substitute for HCPL-4534?

A: A substitute must match all of the following: 3750Vrms isolation voltage, 2-channel configuration, transistor output, DC input, 15-50% current transfer ratio @ 16mA, 200ns/600ns switching times, 20V max output, 8mA per-channel output, 1.5V forward voltage, 25mA max forward current, -55°C to 100°C operating range, and 8-DIP through-hole package.

Q: Are there any differences in circuit behavior between HCPL-4534 and HCPL-4534-000E?

A: No. Both parts deliver identical electrical performance. All switching characteristics, isolation ratings, current transfer ratios, and output specifications are equivalent.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. If RoHS3 compliance is mandated, use HCPL-4534-000E. If RoHS compliance is not required, either part is suitable based on availability and cost.

Q: Is the 8-DIP package compatible with standard through-hole PCB assembly?

A: Yes. Both parts use standard 8-DIP (0.300", 7.62mm) through-hole packaging compatible with conventional PCB assembly processes and DIP sockets.
