Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (Matching CTR Range):

The CNY17-2X007T and CNY17-2X017T are direct electrical equivalents to the CNY17-2S(TB), maintaining the identical current transfer ratio range of 63% to 125% at 10mA. Both parts are manufactured by Vishay Semiconductor Opto Division with ROHS3 compliance and REACH unaffected status. These parts are available in Tape & Reel packaging with higher inventory levels (2052 and 8400 units respectively) compared to the original part.

Higher CTR Performance Alternatives:

The CNY17-3X007, CNY17-3X007T, CNY17-3X017, and CNY17-3X017T provide elevated current transfer ratio performance (100% to 200% at 10mA). These parts maintain all other critical electrical and mechanical parameters and are suitable for applications requiring higher gain characteristics. Inventory availability ranges from 1637 to 4190 units.

Maximum CTR Performance Alternative:

The CNY17-4X007T delivers the highest current transfer ratio range (160% to 320% at 10mA) with the largest inventory availability (35400 units). This part is packaged in Cut Tape (CT) & Digi-Reel® format and is suitable for applications requiring maximum optical coupling efficiency.

Lower CTR Performance Alternative:

The CNY17-1X007T provides a lower current transfer ratio range (40% to 80% at 10mA) and is available in Cut Tape (CT) & Digi-Reel® packaging with the highest inventory level (12660 units). This part is suitable for applications with different gain requirements.

All substitute parts maintain the 5000Vrms isolation voltage, single channel configuration, DC input type, transistor with base output, surface mount 6-SMD gull wing package, and -55°C to 110°C operating temperature range of the original CNY17-2S(TB).

Frequently Asked Questions (FAQ)

Q: Can CNY17-2X007T or CNY17-2X017T be used as direct replacements for CNY17-2S(TB)?

A: Yes. Both CNY17-2X007T and CNY17-2X017T maintain identical current transfer ratio specifications (63% to 125% at 10mA) and all critical electrical parameters. The primary difference is packaging format (Tape & Reel versus the original format) and manufacturer (Vishay Semiconductor Opto Division versus Everlight Electronics Co Ltd). Both are ROHS3 compliant with unlimited moisture sensitivity rating.

Q: What is the difference between CNY17-3X007 and CNY17-3X007T?

A: Both parts have identical electrical specifications with current transfer ratio of 100% to 200% at 10mA. The difference is packaging format: CNY17-3X007 is supplied in Tube packaging, while CNY17-3X007T is supplied in Tape & Reel (TR) packaging. Tape & Reel format is typically preferred for automated assembly processes.

Q: Can I use CNY17-4X007T if my circuit requires lower current transfer ratio?

A: The CNY17-4X007T has a current transfer ratio range of 160% to 320% at 10mA, which is higher than the CNY17-2S(TB) range of 63% to 125%. While the part is electrically compatible in terms of isolation voltage, package, and output type, the higher CTR may affect circuit behavior. Circuit design verification is necessary to confirm suitability for specific application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. Additionally, all Vishay Semiconductor Opto Division parts carry REACH unaffected designation.

Q: What packaging options are available for CNY17-2 equivalent parts?

A: Equivalent parts with matching 63% to 125% current transfer ratio are available in Tape & Reel (TR) packaging format (CNY17-2X007T and CNY17-2X017T). Higher CTR variants are available in Tube (CNY17-3X007, CNY17-3X017) and Tape & Reel (CNY17-3X007T, CNY17-3X017T) formats. The CNY17-4X007T highest CTR variant is available in Cut Tape (CT) & Digi-Reel® format.

Q: Do all substitute parts operate within the same temperature range?

A: Yes. All substitute parts operate within the -55°C to 110°C temperature range, matching the CNY17-2S(TB) specification.

Q: What is the maximum output voltage rating for substitute parts?

A: Substitute parts are rated for 70V maximum output voltage, compared to the CNY17-2S(TB) rated at 80V. This represents a 10V reduction in maximum output voltage rating. Circuit designs operating near the 80V limit require verification for compatibility with the 70V rated substitutes.

Q: How do switching times compare between the main part and substitutes?

A: The CNY17-2S(TB) has turn on/turn off times of 10µs and 9µs respectively. All Vishay substitute parts feature faster switching with turn on/turn off times of 3µs and 2.3µs respectively. This represents approximately 3x faster switching performance in substitute parts, which may affect circuit timing characteristics.
