Key Parameters

Substitute Part Grouping Explanation

The CNY17-2XSM qualifies as a parametric equivalent to the CNY17-2SM based on the following critical substitution criteria:

• Isolation Voltage: Both parts maintain 5300Vrms isolation voltage
• Number of Channels: Single-channel configuration in both devices
• Output Type: Transistor with base output in both parts
• Current Transfer Ratio: Identical range of 63% to 125% @ 10mA
• Maximum Output Voltage: 70V specification maintained
• Maximum Output Current: 50mA per channel in both parts
• Operating Temperature Range: -55°C ~ 100°C identical
• Package Type: 6-SMD, Gull Wing in both configurations
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited) for both

The CNY17-2XSM represents an alternative within the same CNY17 base product family with equivalent electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CNY17-2SM and CNY17-2XSM are active products with full ROHS3 compliance and REACH unaffected status. The CNY17-2XSM offers improved switching performance with faster turn-on time (3µs versus 4.2µs) and significantly faster turn-off time (2.3µs versus 23µs), along with reduced rise and fall times. Selection between these parts should be based on application timing requirements and current inventory availability. Both parts maintain identical electrical isolation, output specifications, and operating temperature ranges, ensuring functional interchangeability within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can CNY17-2XSM replace CNY17-2SM in existing designs?

A: Yes. Both parts share identical isolation voltage (5300Vrms), output type (transistor with base), maximum output voltage (70V), maximum output current (50mA), current transfer ratio range (63-125% @ 10mA), and operating temperature range (-55°C ~ 100°C). The CNY17-2XSM exhibits faster switching characteristics but maintains full electrical compatibility.

Q: What are the key differences between these parts?

A: The primary differences are switching speed parameters. CNY17-2XSM provides faster turn-on (3µs vs 4.2µs), significantly faster turn-off (2.3µs vs 23µs), and faster rise/fall times (2µs vs 3µs/14µs). All other electrical and mechanical specifications remain identical.

Q: Are both parts available in the same package?

A: Yes. Both CNY17-2SM and CNY17-2XSM use 6-SMD, Gull Wing surface mount packaging with identical mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, classified as MSL 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Q: Which part should I select for high-speed switching applications?

A: The CNY17-2XSM is suitable for applications requiring faster switching response due to its improved turn-off time (2.3µs versus 23µs) and faster rise/fall times. Selection should be based on specific application timing requirements within the specified parameter ranges.
