Substitute Part Grouping Explanation

Substitution eligibility for the CNY75CSM is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 1
• Output Type: Transistor with Base
• Current Transfer Ratio range: 160% to 320% @ 10mA
• Voltage - Output (Max): 90V
• Current - Output / Channel: 50mA
• Package / Case: 6-SMD, Gull Wing
• Operating Temperature range: -55°C ~ 100°C
• Input Type: DC

The CNY75CXSM qualifies as a parametric equivalent based on matching all isolation voltage, channel configuration, output type, output current rating, package form factor, and operating temperature specifications. Timing characteristics (Turn On/Turn Off and Rise/Fall times) differ between the main part and substitute but remain within acceptable operational parameters for the optoisolator category.

Parameter Comparison

Engineering Selection Recommendations

Both CNY75CSM and CNY75CXSM are active production parts manufactured by Isocom Components 2004 LTD with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and application timing requirements. The CNY75CXSM exhibits longer turn-on and turn-off times (11µs and 37.5µs respectively, compared to 7µs and 5µs for the CNY75CSM), which may impact applications with strict switching speed requirements. Both parts maintain equivalent isolation voltage, output current capacity, and thermal operating range. Current inventory levels show 790 units of CNY75CXSM available compared to 718 units of CNY75CSM.

Frequently Asked Questions (FAQ)

Q: Can CNY75CXSM replace CNY75CSM in existing designs?

A: Yes, CNY75CXSM qualifies as a parametric equivalent for CNY75CSM. Both parts share identical isolation voltage (5300Vrms), channel configuration (1 channel), output type (transistor with base), output current rating (50mA), package form factor (6-SMD, Gull Wing), and operating temperature range (-55°C to 100°C). The primary difference is switching timing characteristics.

Q: What are the timing differences between these parts?

A: CNY75CSM specifies turn-on/turn-off times of 7µs and 5µs with rise/fall times of 4.2µs and 4.7µs. CNY75CXSM specifies turn-on/turn-off times of 11µs and 37.5µs with identical rise/fall times of 4.2µs and 4.7µs. Applications requiring faster switching response should prioritize CNY75CSM.

Q: Are both parts RoHS compliant?

A: Yes, both CNY75CSM and CNY75CXSM are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the package compatibility between these parts?

A: Both parts use identical 6-SMD, Gull Wing surface mount packaging, ensuring direct mechanical and electrical compatibility on PCB layouts designed for either part number.

Q: Which part should I select based on current availability?

A: CNY75CXSM has higher current inventory (790 units) compared to CNY75CSM (718 units). For applications without strict timing constraints, CNY75CXSM offers better supply availability.
