Parameter Comparison

Engineering Selection Recommendations

The HCPL-263L and HCPL-263L-000E are electrically and mechanically identical. Both parts are active products from Broadcom Limited with identical electrical specifications, pin configurations, and performance characteristics.

The primary distinction between these parts is regulatory compliance status. The HCPL-263L-000E carries ROHS3 compliance certification, while the HCPL-263L is RoHS non-compliant. Selection between these parts should be based on project compliance requirements and applicable regulatory standards in the target market or application.

Both parts maintain identical isolation voltage, channel count, output type, data rate, and thermal operating range. PCB layout, component placement, and circuit design require no modification when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can HCPL-263L-000E be used as a direct replacement for HCPL-263L?

A: Yes. Both parts are electrically and mechanically identical with matching pin configurations, electrical specifications, and performance characteristics. No circuit modifications or PCB redesign is required for substitution.

Q: What is the difference between HCPL-263L and HCPL-263L-000E?

A: The HCPL-263L-000E is ROHS3 compliant, while the HCPL-263L is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions.

Q: Which part should I select for new designs?

A: Selection depends on regulatory compliance requirements applicable to your application and target market. If ROHS3 compliance is required, use HCPL-263L-000E. If compliance is not a requirement, either part is suitable.

Q: Can these parts be used interchangeably on existing PCBs?

A: Yes. The identical package, pinout, and electrical specifications allow direct substitution without PCB modification.

Q: What is the isolation voltage rating for both parts?

A: Both HCPL-263L and HCPL-263L-000E provide 3750Vrms galvanic isolation between input and output channels.

Q: What is the maximum data rate supported by these optoisolators?

A: Both parts support data rates up to 15MBd with maximum propagation delays of 75ns for both rising and falling edges.
