Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCNR201#350 is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 5000Vrms
• Number of channels: 1
• Output type: Photovoltaic, Linearized
• Current transfer ratio range: 0.36% to 0.72% @ 10mA
• Input type: DC
• Forward voltage: 1.6V typical
• Maximum forward current: 25 mA
• Operating temperature range: -55°C to 100°C
• Base product number: HCNR201

The HCNR201-350E qualifies as a direct substitute based on identical electrical performance specifications and functional characteristics. The primary distinction lies in packaging format and product status, with the substitute offering active availability and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The HCNR201-350E is the designated substitute for the obsolete HCNR201#350. Selection of the HCNR201-350E is supported by the following factors:

• Identical electrical performance across all specified parameters
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance versus non-compliant status of the original part, meeting current regulatory requirements
• Maintained isolation voltage, current transfer ratio, and operating temperature specifications
• Same base product family (HCNR201) confirming functional equivalence

Frequently Asked Questions (FAQ)

Q: Can HCNR201-350E be used as a direct replacement for HCNR201#350?

A: Yes. The HCNR201-350E provides identical electrical performance across all critical parameters including isolation voltage, current transfer ratio, forward voltage, and operating temperature range. Both parts share the same base product number and output characteristics.

Q: What is the primary difference between these parts?

A: The HCNR201#350 is obsolete with RoHS non-compliant status, while the HCNR201-350E is an active product with ROHS3 compliance. The supplier device package designation differs (8-SMD versus 8-DIP Gull Wing), though both maintain surface mount mounting type and identical functional specifications.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist from an electrical standpoint. Both parts are single-channel photovoltaic optoisolators with 5000Vrms isolation and identical transfer characteristics. PCB layout and footprint considerations should be evaluated based on the specific package format used in the target application.

Q: What certifications and compliance standards apply?

A: The HCNR201-350E meets ROHS3 compliance and REACH unaffected status. Both parts carry EAR99 export classification and the same HTSUS code (8541.49.8000). Moisture sensitivity level is rated as 1 (Unlimited) for both variants.
