Engineering Selection Recommendations
Parametric Equivalent (Direct Replacement): CNY17-2X007 from Vishay Semiconductor Opto Division is a parametric equivalent with identical electrical specifications, isolation voltage, current transfer ratio range, output current rating, and operating temperature range. Both parts are ROHS3 compliant with MSL 1 rating.
Higher Isolation Voltage Alternative: CNY17-2XSM from Isocom Components 2004 LTD provides 5300Vrms isolation with matching current transfer ratio (63%-125%) and output current (50mA). Operating temperature maximum is reduced to 100°C. This part is suitable for applications requiring enhanced isolation margin.
Higher Output Current Alternatives: CNY17-2-500E (Broadcom Limited) and CNY17-2S (Lite-On Inc.) maintain the 63%-125% current transfer ratio while increasing output current to 150mA and reducing Vce saturation to 300mV. Operating temperature maximum is 100°C. These parts are suitable for higher load current applications.
Higher Current Transfer Ratio Alternatives: CNY17-3S, CNY17-3S-TA, and CNY17-3S-TA1 (all Lite-On Inc.) provide 100%-200% current transfer ratio with 150mA output current. CNY17-3S-TA and CNY17-3S-TA1 are available in Tape & Reel packaging for high-volume production. Operating temperature maximum is 100°C.
Lower Current Transfer Ratio Alternatives: CNY17-1-300E (Broadcom Limited) and CNY17-1S (Lite-On Inc.) provide 40%-80% current transfer ratio with 150mA output current. These parts are suitable for applications where lower current transfer ratio is acceptable.
All substitute parts maintain 5000Vrms or higher isolation voltage, single-channel transistor with base output configuration, 6-SMD gull wing package, surface mount mounting type, and ROHS3 compliance.
Frequently Asked Questions (FAQ)
Q: Can CNY17-2X007 be used as a direct replacement for CNY17-2X009? A: Yes. CNY17-2X007 is a parametric equivalent with identical isolation voltage (5000Vrms), current transfer ratio range (63%-125%), output current (50mA), and operating temperature range (-55°C to 110°C). Both are ROHS3 compliant with MSL 1 rating.
Q: What is the difference between CNY17-2X009 and CNY17-2XSM? A: CNY17-2XSM provides higher isolation voltage (5300Vrms vs 5000Vrms) and is manufactured by Isocom Components instead of Vishay. Current transfer ratio and output current specifications are identical. Operating temperature maximum is reduced from 110°C to 100°C.
Q: Can I use CNY17-2S instead of CNY17-2X009 if my application requires higher output current? A: Yes, if your circuit design accommodates the higher output current rating (150mA vs 50mA). CNY17-2S maintains the same current transfer ratio range (63%-125%) and isolation voltage (5000Vrms). Operating temperature maximum is 100°C instead of 110°C. Verify that the lower Vce saturation (300mV vs 400mV) is compatible with your output stage design.
Q: What packaging options are available for CNY17 optoisolators? A: Tube packaging is standard for most variants. CNY17-2-500E is available in Cut Tape (CT) & Digi-Reel format. CNY17-3S-TA and CNY17-3S-TA1 are available in Tape & Reel (TR) packaging for automated assembly and high-volume production.
Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level rating.
Q: What is the minimum operating temperature for all substitute parts? A: All substitute parts operate at -55°C minimum. Maximum operating temperature varies: CNY17-2X009 reaches 110°C, while most alternatives are rated to 100°C maximum.
Q: Can CNY17-3S-TA1 be used in place of CNY17-2X009? A: CNY17-3S-TA1 is functionally compatible if your application can accommodate the higher current transfer ratio (100%-200% vs 63%-125%), higher output current (150mA vs 50mA), and lower maximum operating temperature (100°C vs 110°C). The Tape & Reel packaging is designed for automated production rather than tube distribution.
