Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CNY17-4G is determined by strict equivalence across the following critical parameters:

• Single-channel configuration
• Isolation voltage of 5300Vrms
• Current transfer ratio range: 160% to 320% @ 10mA
• Transistor output with base connection
• Maximum output voltage of 70V
• Maximum output current of 50mA per channel
• 6-DIP through-hole package format
• Operating temperature range of -55°C to 100°C
• DC input type

Only parts meeting all these specifications are classified as direct parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

The CNY17-4XG is a direct parametric equivalent to the CNY17-4G. Both parts are manufactured by Isocom Components 2004 LTD within the CNY17-4 series and share identical electrical and mechanical specifications. Both components maintain active product status and comply with ROHS3 and REACH requirements. Selection between these parts may be based on inventory availability, with CNY17-4G currently stocked at 831 units and CNY17-4XG at 750 units. No performance differentiation exists between the two parts for applications requiring single-channel optoisolation at 5300Vrms with transistor output control.

Frequently Asked Questions (FAQ)

Q: Can CNY17-4XG be used as a direct replacement for CNY17-4G in existing designs?

A: Yes. The CNY17-4XG meets all electrical and mechanical specifications of the CNY17-4G, including isolation voltage, current transfer ratio, output characteristics, and package format. No circuit modifications are required.

Q: Are there any differences in compliance or certifications between CNY17-4G and CNY17-4XG?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level ratings.

Q: What determines whether a part qualifies as a substitute for CNY17-4G?

A: A substitute must match all critical parameters: single-channel configuration, 5300Vrms isolation, 160-320% current transfer ratio at 10mA, transistor output with base, 70V maximum output voltage, 50mA output current, 6-DIP package, -55°C to 100°C operating range, and DC input type.

Q: Are there any package or pinout differences between CNY17-4G and CNY17-4XG?

A: No. Both parts use the 6-DIP (0.400", 10.16mm) through-hole package with identical pinout and mounting requirements.

Q: What is the current transfer ratio specification, and why is it important for substitution?

A: The current transfer ratio ranges from 160% to 320% at 10mA input current. This parameter defines the optical coupling efficiency and must remain within this range for functional equivalence. Both parts meet this specification identically.
