• Identical channel configuration (2 channels)
• Matching common mode transient immunity (1kV/µs)
• Identical input and output types (DC input, Open Collector Schottky Clamped output)
• Matching output current rating (50 mA per channel)
• Identical data rate specification (10MBd)
• Matching supply voltage range (4.5V ~ 5.5V)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package and mounting specifications (8-SMD, Gull Wing, Surface Mount)

Parameter Comparison

Engineering Selection Recommendations

The HCPL-263A-300E is the direct equivalent for the HCPL-263A#300. All electrical and mechanical parameters are identical. The primary advantage of selecting HCPL-263A-300E is its active product status and ROHS3 compliance, which addresses regulatory requirements for new designs and production continuity. The original part's discontinued status makes HCPL-263A-300E the appropriate selection for ongoing applications.

Frequently Asked Questions (FAQ)

Q: Can HCPL-263A-300E be used as a direct replacement for HCPL-263A#300?

A: Yes. Both parts share identical electrical specifications, including isolation voltage, channel configuration, output type, data rate, and timing characteristics. The package and mounting specifications are also identical (8-SMD, Gull Wing, Surface Mount).

Q: What is the difference between HCPL-263A#300 and HCPL-263A-300E?

A: The primary differences are product status and compliance. HCPL-263A#300 is discontinued, while HCPL-263A-300E is active. HCPL-263A-300E is ROHS3 compliant, whereas HCPL-263A#300 is RoHS non-compliant. All functional and electrical parameters remain identical.

Q: Are there any packaging differences between these parts?

A: Both parts use the same 8-SMD, Gull Wing package for surface mount applications. The supplier device package designation is 8-DIP Gull Wing for both. No PCB layout modifications are required when substituting between these parts.

Q: Why should I select HCPL-263A-300E over HCPL-263A#300?

A: HCPL-263A-300E should be selected because HCPL-263A#300 is discontinued at DiGi Electronics. HCPL-263A-300E maintains full electrical and mechanical compatibility while offering active availability and ROHS3 compliance for regulatory adherence.

Q: Are the isolation voltage and CMTI specifications identical?

A: Yes. Both parts provide 3750Vrms isolation voltage and 1kV/µs common mode transient immunity. These critical parameters for high-speed digital isolation applications are unchanged between the two parts.
