• Common Mode Transient Immunity: 10kV/µs minimum
• Propagation Delay: 700ns maximum (both tpLH and tpHL)
• Output Current Capability: 200mA per output state, 400mA peak
• Output Supply Voltage Range: 10V ~ 30V
• Package Type: 8-SOIC surface mount
• Operating Temperature Range: -40°C ~ 100°C

The HCPL-0302-500E is a direct functional equivalent manufactured by Broadcom Limited, maintaining identical electrical specifications and mechanical compatibility while offering improved product status and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-0302-500E is the direct substitute for the HCPL-0302-500. Both parts are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical parameters. The HCPL-0302-500E offers two significant advantages:

1. Product Status: The HCPL-0302-500E maintains active production status, ensuring long-term supply chain availability and support.

2. Regulatory Compliance: The HCPL-0302-500E is ROHS3 compliant, whereas the original part is RoHS non-compliant. This distinction is material for applications subject to RoHS directives and environmental regulations.

Both parts carry identical certifications (CSA, UR) and maintain the same ECCN and HTSUS classifications. Pin-for-pin compatibility and functional equivalence are guaranteed across all specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-0302-500E be used as a direct replacement for the HCPL-0302-500?

A: Yes. The HCPL-0302-500E is a direct functional and pin-compatible substitute. All electrical specifications, isolation voltage, propagation delay, output current ratings, and operating temperature ranges are identical. The 8-SOIC package dimensions and pinout are unchanged.

Q: What is the difference between the HCPL-0302-500 and HCPL-0302-500E?

A: The primary differences are product status and regulatory compliance. The HCPL-0302-500E is in active production and is ROHS3 compliant, while the original part is discontinued and RoHS non-compliant. All electrical and mechanical specifications remain identical.

Q: Are there any PCB layout or thermal considerations when substituting these parts?

A: No layout or thermal modifications are required. Both parts use the same 8-SOIC package footprint and have identical thermal characteristics. Existing PCB designs require no changes.

Q: Does the HCPL-0302-500E support the same isolation voltage and common mode transient immunity?

A: Yes. The HCPL-0302-500E maintains the full 3750Vrms isolation voltage and 10kV/µs common mode transient immunity specification. No performance degradation occurs in high-voltage switching applications.

Q: What packaging options are available for the HCPL-0302-500E?

A: The HCPL-0302-500E is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.
