Substitute Part Grouping Explanation

Substitution eligibility for the HCNR201#050 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Type: Photovoltaic, Linearized (mandatory match)
• Current Transfer Ratio Range: 0.36% to 0.72% @ 10mA (mandatory match)
• Input Type: DC (mandatory match)
• Package / Case: 8-DIP (0.400", 10.16mm) (mandatory match)
• Forward Voltage (Vf): 1.6V typical (mandatory match)
• Maximum Forward Current (If): 25 mA (mandatory match)
• Operating Temperature Range: -55°C ~ 100°C (mandatory match)

The HCNR201-050E variant meets all electrical and mechanical equivalence criteria and is classified as a direct substitute within the HCNR201 base product family.

Parameter Comparison

Engineering Selection Recommendations

Both HCNR201#050 and HCNR201-050E are electrically and mechanically equivalent optoisolators within the HCNR201 product family. Selection between these parts should be based on the following criteria:

HCNR201#050: Select this part number when RoHS non-compliant status is acceptable for the application. Current inventory availability is 985 units.

HCNR201-050E: Select this part number when ROHS3 compliance is required. This variant provides higher inventory availability at 1872 units and meets enhanced environmental and regulatory standards.

Both parts maintain identical electrical performance, isolation voltage, current transfer ratios, operating temperature range, and package configuration. The choice between them is determined by regulatory compliance requirements and supply chain availability rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are HCNR201#050 and HCNR201-050E electrically interchangeable?

A: Yes. Both parts are electrically identical with matching isolation voltage (5000Vrms), current transfer ratios (0.36% to 0.72% @ 10mA), forward voltage (1.6V typical), and operating temperature range (-55°C ~ 100°C).

Q: What is the primary difference between these two part numbers?

A: The primary difference is RoHS compliance status. HCNR201#050 is RoHS non-compliant, while HCNR201-050E is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Can I use HCNR201-050E as a direct replacement for HCNR201#050 in existing designs?

A: Yes. The HCNR201-050E is a direct substitute with identical package configuration (8-DIP), pin assignments, and electrical specifications. No circuit modifications are required.

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

A: No. Both parts use the same 8-DIP (0.400", 10.16mm) through-hole package with identical mounting requirements and PCB footprint.

Q: Which part should I specify for new designs?

A: Specify HCNR201-050E for new designs if ROHS3 compliance is required by your application or regulatory environment. Both parts are active in production status.

Q: What is the isolation voltage rating for these optoisolators?

A: Both parts provide 5000Vrms galvanic isolation, suitable for high-voltage isolation applications requiring single-channel photovoltaic linearized output.
