Substitute Part Grouping Explanation

Substitute parts for the CNY17-2S-TA1 are classified based on Current Transfer Ratio (CTR) performance bands within the CNY17 optoisolator series. All substitutes maintain identical isolation voltage (5000Vrms), output type (transistor with base), maximum output voltage (70V), output current (150mA), rise/fall time (5µs), operating temperature range (-55°C ~ 100°C), and package configuration (6-SMD, Gull Wing).

The CNY17-2S-TA1 operates in the 63-125% CTR band. Substitute parts are grouped as follows:

• Parametric Equivalent (Same CTR Band): CNY17-2-500E maintains the 63-125% CTR specification, providing direct functional equivalence.
• MFR Recommended (Higher CTR Bands): CNY17-3-500E (100-200% CTR) and CNY17-4-500E (160-320% CTR) offer enhanced current transfer performance for applications requiring higher gain characteristics.

All substitutes are manufactured by Broadcom Limited, share the same base product number (CNY17), and maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

CNY17-2-500E (Parametric Equivalent): Select this substitute when direct parametric equivalence is required. The CNY17-2-500E maintains the identical 63-125% CTR band as the CNY17-2S-TA1, ensuring matched performance characteristics. This part is manufactured by Broadcom Limited and carries ROHS3 compliance with REACH Unaffected status. Packaging is available in Cut Tape (CT) and Digi-Reel® format.

CNY17-3-500E (MFR Recommended - Enhanced Performance): Select this substitute for applications where higher current transfer ratio (100-200% CTR band) provides design margin or improved switching performance. This part is manufactured by Broadcom Limited with ROHS3 compliance and REACH Unaffected status. Package configuration is 6-SMD, Gull Wing in Tape & Reel format.

CNY17-4-500E (MFR Recommended - Maximum Performance): Select this substitute for applications requiring the highest current transfer ratio (160-320% CTR band) within the CNY17 series. This part is manufactured by Broadcom Limited with ROHS3 compliance and REACH Unaffected status. Package configuration is 6-SMD, Gull Wing in Tape & Reel format.

All substitute parts maintain active product status and are suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can CNY17-2-500E be used as a direct replacement for CNY17-2S-TA1?

A: Yes. The CNY17-2-500E is a parametric equivalent with identical Current Transfer Ratio specifications (63-125% @ 10mA), isolation voltage, output configuration, and package type. Both parts operate within the same performance band and are functionally interchangeable.

Q: What is the difference between CNY17-2-500E, CNY17-3-500E, and CNY17-4-500E?

A: The primary difference is the Current Transfer Ratio performance band. CNY17-2-500E operates at 63-125% CTR, CNY17-3-500E at 100-200% CTR, and CNY17-4-500E at 160-320% CTR. All other electrical and mechanical parameters remain identical. Higher CTR values indicate greater current gain through the optoisolator.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts share the identical 6-SMD, Gull Wing package configuration and surface mount mounting type. PCB footprints and assembly processes remain unchanged.

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

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape and Digi-Reel® packaging provides smaller quantities cut from the reel for manual handling or lower-volume applications. Electrical and mechanical specifications are identical.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CNY17-2S-TA1 and all substitute parts (CNY17-2-500E, CNY17-3-500E, CNY17-4-500E) are ROHS3 compliant. Broadcom-manufactured substitutes also carry REACH Unaffected status.

Q: Can I use a higher CTR part (CNY17-3-500E or CNY17-4-500E) in place of CNY17-2S-TA1?

A: Higher CTR parts can be used in applications where the circuit design accommodates increased current transfer. However, this substitution requires circuit analysis to confirm compatibility with input drive requirements and output load conditions. The higher CTR does not affect isolation voltage, output voltage limits, or output current ratings.
