Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CNY17-2-V is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor with Base
• Package / Case: 6-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Input Type: DC

Secondary Compatibility Parameters:

• Current - DC Forward (If) (Max): 60 mA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts match the primary criteria. Variations in Current Transfer Ratio, Turn On/Turn Off Time, Rise/Fall Time, Voltage - Output (Max), and Vce Saturation are acceptable within the optoisolator transistor category, provided the substitute part meets or exceeds the isolation voltage and maintains the same package and output configuration.

Parameter Comparison

Engineering Selection Recommendations

CNY17-1 (Lite-On Inc.) This substitute maintains 5000Vrms isolation, single-channel transistor output, and 6-DIP through-hole package. Current Transfer Ratio ranges from 40% to 80%, which is lower than the CNY17-2-V. Operating temperature range is -55°C to 100°C, which is 10°C lower at the upper limit. All parts are ROHS3 compliant with MSL 1. This part is suitable for applications where the lower Current Transfer Ratio is acceptable and operating temperature does not exceed 100°C.

CNY17-1X001 (Vishay Semiconductor Opto Division) This substitute provides 5000Vrms isolation with identical package and output configuration. Current Transfer Ratio is 40% to 80%, matching CNY17-1. Operating temperature extends to 110°C, matching the CNY17-2-V. Vce Saturation is 400mV, which is 100mV higher than the main part. All compliance certifications are met. This part is suitable for applications requiring the full -55°C to 110°C temperature range.

CNY17-3 (Quality Technologies) This substitute provides single-channel transistor output in 6-DIP through-hole package. Isolation voltage is not specified in the provided data. Current Transfer Ratio maximum is 100% at 10mA. Due to incomplete isolation voltage specification, this part should be verified against application requirements before selection.

CNY17-4 (Lite-On Inc.) This substitute maintains 5000Vrms isolation, single-channel transistor output, and 6-DIP through-hole package. Current Transfer Ratio ranges from 160% to 320%, which is significantly higher than the CNY17-2-V. Operating temperature range is -55°C to 100°C. All compliance certifications are met. This part is suitable for applications where higher Current Transfer Ratio is beneficial and operating temperature does not exceed 100°C.

Frequently Asked Questions (FAQ)

Q: Can CNY17-1 be used as a direct replacement for CNY17-2-V? A: CNY17-1 matches the isolation voltage, package type, and output configuration. However, the Current Transfer Ratio is lower (40-80% versus 63-125%), and the maximum operating temperature is 100°C instead of 110°C. Substitution is valid only if the application tolerates these parameter differences.

Q: What is the primary difference between CNY17-2-V and CNY17-4? A: Both parts share 5000Vrms isolation and 6-DIP package. The main difference is Current Transfer Ratio: CNY17-2-V ranges from 63% to 125%, while CNY17-4 ranges from 160% to 320%. CNY17-4 is suitable for applications requiring higher current transfer efficiency.

Q: Is CNY17-1X001 compatible with high-temperature applications? A: Yes. CNY17-1X001 operates from -55°C to 110°C, matching the CNY17-2-V temperature range. Both parts are suitable for applications requiring the full extended temperature range.

Q: Why is CNY17-3 listed as a substitute if isolation voltage is not specified? A: CNY17-3 matches the package, mounting type, output configuration, and input type. However, the isolation voltage specification is incomplete in the provided data. Circuit designers must verify isolation voltage requirements independently before selecting this part.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All identified substitute parts (CNY17-1, CNY17-1X001, CNY17-3, and CNY17-4) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the CNY17-2-V compliance profile.

Q: What is the significance of the 6-DIP package specification? A: The 6-DIP (0.300", 7.62mm) package is a standard through-hole configuration. All substitute parts use this identical package, ensuring mechanical and electrical compatibility in existing PCB layouts without modification.

Q: Can CNY17-1X001 replace CNY17-2-V in all applications? A: CNY17-1X001 is compatible for most applications due to matching isolation voltage, temperature range, and package. The Vce Saturation is 100mV higher (400mV versus 300mV), which may affect performance in applications with tight saturation voltage requirements.
