Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-0534#500 is determined by strict equivalence across the following critical parameters:

• Number of Channels: 2
• Voltage - Isolation: 3750Vrms
• Current Transfer Ratio range: 15% (Min) to 50% (Max) @ 16mA
• Output Type: Transistor
• Voltage - Output (Max): 20V
• Current - Output / Channel: 8mA
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Operating Temperature range: -55°C ~ 100°C

The HCPL-0534-500E meets all these parameters and is classified as a parametric equivalent. Substitution is valid when these electrical and mechanical specifications are maintained within the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-0534-500E is the direct parametric equivalent for the discontinued HCPL-0534#500. Both parts share identical electrical and mechanical specifications across all critical isolation, switching, and output parameters.

The HCPL-0534-500E is currently in active production status with higher inventory availability. The substitute part carries ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Selection of the HCPL-0534-500E is appropriate for new designs and ongoing production requiring the HCPL-0534 series functionality. The active product status ensures long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-0534-500E be used as a direct replacement for the HCPL-0534#500?

A: Yes. The HCPL-0534-500E is a parametric equivalent with identical electrical specifications across isolation voltage, channel count, current transfer ratio, switching times, output voltage, and output current. Both parts use the same 8-SOIC package and operate across the same temperature range.

Q: What is the difference between HCPL-0534#500 and HCPL-0534-500E?

A: The primary differences are product status and regulatory compliance. The HCPL-0534#500 is discontinued and RoHS non-compliant. The HCPL-0534-500E is active production and ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What inventory status should I expect?

A: The HCPL-0534#500 has 844 pieces in stock but is discontinued. The HCPL-0534-500E has 2830 pieces in stock and is in active production, providing better long-term availability.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance is a regulatory and material composition requirement, not a functional specification. Both parts deliver identical electrical performance in circuit applications.
