CNY17F-2S-TA Equivalent & Substitute Parts

Part Overview

The CNY17F-2S-TA is an optoisolator with transistor output manufactured by Lite-On Inc., designed for high-voltage isolation applications requiring 5000Vrms isolation rating. This single-channel device operates in the -55°C to 100°C temperature range and is packaged in a 6-SMD surface mount configuration. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity level rating.

Substitute parts are identified when design requirements allow flexibility in current transfer ratio ranges, output current specifications, isolation voltage ratings, or packaging formats while maintaining core functional compatibility for transistor output optoisolation applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CNY17F-2S-TA is determined by the following criteria:

Core Compatibility Requirements:

• Single-channel transistor output optoisolator configuration
• 6-SMD surface mount package with gull wing leads
• Isolation voltage rating of 5000Vrms or higher
• Maximum output voltage of 70V or greater
• Operating temperature range encompassing -55°C to 100°C
• DC input type
• ROHS3 compliance and unlimited MSL rating

Flexible Parameters Allowing Substitution:

• Current Transfer Ratio range (63-125% for main part; substitutes may vary from 63-320%)
• Output current per channel (main part: 150mA; substitutes: 50mA minimum acceptable)
• Rise/Fall time specifications
• Turn-on/Turn-off time specifications
• Vce saturation voltage (main part: 300mV; substitutes: 400mV maximum)
• Forward voltage (Vf) specifications
• Packaging format (tube or tape & reel)

All identified substitute parts meet the core compatibility requirements while offering variations in performance characteristics or packaging that may suit alternative design scenarios.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, meeting regulatory requirements equivalent to the CNY17F-2S-TA.

CNY17F-2X007T (Vishay Semiconductor Opto Division): Maintains identical current transfer ratio range (63-125% @ 10mA) and isolation voltage (5000Vrms) as the main part. Offers extended operating temperature range to 110°C and tape & reel packaging. Output current is reduced to 50mA. Vce saturation increases to 400mV.

CNY17F-2XSM (Isocom Components 2004 LTD): Provides higher isolation voltage (5300Vrms) with identical current transfer ratio range (63-125% @ 10mA). Output current reduced to 50mA with 400mV Vce saturation. Available in tube packaging.

CNY17F-3XSM (Isocom Components 2004 LTD): Offers elevated isolation voltage (5300Vrms) with higher current transfer ratio range (100-200% @ 10mA). Output current 50mA. Tube packaging. Slower switching characteristics with extended turn-off time (23µs) and fall time (14µs).

CNY17F-4XSM (Isocom Components 2004 LTD): Provides highest current transfer ratio range (160-320% @ 10mA) with 5300Vrms isolation. Output current 50mA. Tube packaging. Faster switching performance with 2µs rise and fall times.

CNY17F-4XSMT&R (Isocom Components 2004 LTD): Highest current transfer ratio range (160-320% @ 10mA) in tape & reel format. Note: Isolation voltage specification differs (7.5Vpk). Slower switching characteristics. Tape & reel packaging for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can CNY17F-2X007T replace CNY17F-2S-TA in all applications?

A: CNY17F-2X007T is compatible where output current requirements do not exceed 50mA. The main part supports 150mA output current; substitution requires circuit redesign if higher output current is needed. Isolation voltage and current transfer ratio ranges are identical.

Q: What is the primary difference between Isocom and Lite-On variants?

A: Isocom variants (CNY17F-2XSM, CNY17F-3XSM, CNY17F-4XSM) provide higher isolation voltage (5300Vrms vs. 5000Vrms) and are available in tube packaging. Current transfer ratio ranges vary by model grade. All maintain 6-SMD gull wing package compatibility.

Q: Which substitute offers the fastest switching performance?

A: CNY17F-4XSM and CNY17F-2X007T both provide 2µs rise and fall times, compared to 5µs for the main part. CNY17F-3XSM exhibits slower switching with 14µs fall time.

Q: Is tape & reel packaging available for all substitutes?

A: Tape & reel packaging is available for CNY17F-2X007T (Vishay) and CNY17F-4XSMT&R (Isocom). CNY17F-2XSM, CNY17F-3XSM, and CNY17F-4XSM are supplied in tube packaging.

Q: What is the significance of current transfer ratio grades?

A: Current transfer ratio determines the output current relative to input current. Higher grades (160-320% for CNY17F-4 series) provide greater output current for equivalent input drive. Lower grades (63-125%) require higher input current to achieve target output levels.

Q: Can CNY17F-4XSMT&R be used as a direct substitute?

A: CNY17F-4XSMT&R differs in isolation voltage specification (7.5Vpk vs. 5000Vrms/5300Vrms for other variants). This part is not recommended as a direct substitute unless isolation voltage requirements are specifically 7.5Vpk or lower.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) rating, matching the regulatory status of CNY17F-2S-TA.
