CNY17-1S(TA)-V Optoisolator Equivalent & Substitute Parts

Part Overview

The CNY17-1S(TA)-V is an optoisolator transistor with base output manufactured by Everlight Electronics Co Ltd. This component provides 5000Vrms isolation with a single channel, DC input, and transistor output with base connection in a 6-SMD surface mount package. The part is Active status and RoHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity).

Substitute parts are necessary to address inventory availability, packaging format requirements (Tube versus Tape & Reel), and application-specific current transfer ratio specifications while maintaining electrical and mechanical compatibility.

• Manufacturer: Lite-On Inc. (substitutes) versus Everlight Electronics Co Ltd (main part)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and RoHS3 compliance with MSL Level 1 (Unlimited). Selection among substitutes depends on application requirements and packaging constraints:

CNY17-1S (Lite-On, Tube): Direct electrical equivalent with matching 40%-80% current transfer ratio range. Suitable for applications requiring the same CTR specification as the main part. Maximum output voltage is 70V versus 80V on the main part. Operating temperature range is -55°C ~ 100°C versus -55°C ~ 110°C on the main part. Tube packaging format.

CNY17-3S (Lite-On, Tube) and CNY17-3S-TA (Lite-On, Tape & Reel): Higher current transfer ratio range of 100%-200% @ 10mA. Identical electrical and mechanical specifications except for CTR and packaging format. CNY17-3S-TA1 (Tape & Reel) provides highest inventory availability at 25,200 pieces.

CNY17-4S (Lite-On, Tube) and CNY17-4S-TA1 (Lite-On, Tape & Reel): Highest current transfer ratio range of 160%-320% @ 10mA. Identical electrical and mechanical specifications except for CTR and packaging format. CNY17-4S-TA1 (Tape & Reel) provides 26,600 pieces in stock.

All Lite-On substitutes feature REACH Unaffected status and identical isolation voltage, channel count, input/output types, and package configuration to the main part.

Frequently Asked Questions (FAQ)

Q: Can CNY17-1S from Lite-On directly replace CNY17-1S(TA)-V from Everlight?

A: Yes. Both parts share identical electrical specifications including 5000Vrms isolation, 1 channel, DC input, transistor output with base, 40%-80% current transfer ratio @ 10mA, 300mV Vce saturation, and 6-SMD Gull Wing package. Both are RoHS3 compliant with MSL Level 1. The maximum output voltage is 70V on the Lite-On part versus 80V on the Everlight part. Operating temperature range is -55°C ~ 100°C on the Lite-On part versus -55°C ~ 110°C on the Everlight part.

Q: What is the difference between CNY17-3S and CNY17-4S?

A: Both parts are identical except for current transfer ratio. CNY17-3S has 100%-200% CTR @ 10mA, while CNY17-4S has 160%-320% CTR @ 10mA. All other electrical and mechanical parameters are identical, including isolation voltage, output voltage, saturation voltage, and package type.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for lower-volume orders and manual assembly. Tape & Reel (TR) packaging is used for automated pick-and-place assembly. Electrically and mechanically, the parts are identical. The "-TA" and "-TA1" designations indicate Tape & Reel format variants.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts from Lite-On are RoHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity), matching the compliance status of the main part CNY17-1S(TA)-V.

Q: What is the maximum operating temperature for substitute parts?

A: All Lite-On substitute parts operate from -55°C to 100°C. The main part CNY17-1S(TA)-V operates from -55°C to 110°C. Applications requiring operation above 100°C must use the Everlight part.

Q: Which substitute part has the highest inventory availability?

A: CNY17-4S-TA1 has the highest inventory at 26,600 pieces in stock, followed by CNY17-3S-TA1 at 25,200 pieces.

Q: Can I use a higher CTR part as a substitute for a lower CTR part?

A: Substitution based on current transfer ratio depends on circuit design. CNY17-4S (160%-320% CTR) and CNY17-3S (100%-200% CTR) have higher CTR ranges than CNY17-1S (40%-80% CTR). Circuit compatibility must be verified based on application requirements.
