Key Parameters

Substitute Part Grouping Explanation

Substitution within the CNY17 optoisolator family is determined by the following critical parameters:

Mandatory Equivalence Criteria:

• Voltage - Isolation: 5000Vrms (all substitutes maintain this specification)
• Number of Channels: 1 (single channel configuration)
• Output Type: Transistor with Base (all maintain base output)
• Voltage - Output (Max): 70V (maximum output voltage rating)
• Package / Case: 6-SMD, Gull Wing (identical mechanical form factor)
• Mounting Type: Surface Mount (all are surface mount)
• Input Type: DC (all accept DC input)

Variable Parameters Affecting Substitution:

• Current Transfer Ratio (CTR): Ranges from 40% to 320% @ 10mA depending on part variant
• Current - Output / Channel: Ranges from 50mA to 150mA
• Operating Temperature: Upper limit varies between 100°C and 110°C
• Packaging Format: Tube or Tape & Reel (TR)
• Manufacturer: Vishay, Lite-On Inc., or Broadcom Limited

Parts are grouped as substitutes when they maintain the core isolation voltage, channel count, output type, and physical package while allowing variation in current transfer ratio and output current capacity based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: CNY17-2X007 from Vishay maintains identical electrical specifications to CNY17-2X019, including current transfer ratio range (63%-125%), output current (50mA), and maximum operating temperature (110°C). Both are Active status products with ROHS3 compliance. This part provides the closest functional replacement with higher inventory availability (2100 Pcs vs 736 Pcs).

Higher Current Output Alternatives: Parts CNY17-3S, CNY17-3S-TA, CNY17-3S-TA1, CNY17-4S, and CNY17-4S-TA1 from Lite-On Inc. and CNY17-3-360E from Broadcom Limited support increased output current (150mA vs 50mA) and lower saturation voltage (300mV vs 400mV). These variants are suitable for applications requiring higher output drive capability. All maintain 5000Vrms isolation and Active product status with ROHS3 compliance. Operating temperature maximum is 100°C, which represents a 10°C reduction from the main part.

Packaging Considerations: Tape & Reel (TR) packaged variants (CNY17-3S-TA, CNY17-3S-TA1, CNY17-4S-TA1) are available for high-volume automated assembly. Tube packaged variants are suitable for lower-volume or manual assembly operations.

Current Transfer Ratio Selection:

• 63%-125% CTR: CNY17-2X019, CNY17-2X007 (lower CTR range)
• 100%-200% CTR: CNY17-3S, CNY17-3S-TA, CNY17-3S-TA1, CNY17-3-360E (mid-range CTR)
• 160%-320% CTR: CNY17-4S, CNY17-4S-TA1 (higher CTR range)
• 40%-80% CTR: CNY17-1S (lowest CTR range)

Frequently Asked Questions (FAQ)

Q: Can CNY17-2X007 be used as a direct replacement for CNY17-2X019? A: Yes. CNY17-2X007 is a parametric equivalent with identical isolation voltage (5000Vrms), current transfer ratio (63%-125%), output current (50mA), saturation voltage (400mV), and operating temperature range (-55°C to 110°C). Both are Vishay products in Active status with ROHS3 compliance and 6-SMD Gull Wing packaging.

Q: What is the difference between Tube and Tape & Reel packaging? A: Tube packaging is used for lower-volume applications and manual assembly. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly in high-volume production. Electrical specifications remain identical; packaging format is the only difference.

Q: Can I use CNY17-3S instead of CNY17-2X019? A: CNY17-3S is compatible from an isolation and package perspective but differs in output current (150mA vs 50mA), current transfer ratio (100%-200% vs 63%-125%), saturation voltage (300mV vs 400mV), and maximum operating temperature (100°C vs 110°C). Use CNY17-3S only if your application requires higher output current and can tolerate the 10°C lower temperature limit.

Q: What does Current Transfer Ratio (CTR) mean? A: CTR is the ratio of output collector current to input LED current, expressed as a percentage. Higher CTR values indicate greater signal transfer efficiency. CNY17-2X019 has a CTR range of 63%-125%, while CNY17-4S has 160%-320%. Select based on your circuit's input current and required output current.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and Active product status, ensuring regulatory compliance for new designs.

Q: What is the maximum isolation voltage for all these parts? A: All parts in this family maintain 5000Vrms isolation voltage, meeting high-voltage isolation requirements across the entire substitute list.
