Substitute Part Grouping Explanation

Substitute parts for the IS660SM are identified based on strict parametric equivalence across critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must match the original part:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 1
• Output Type: Darlington
• Current Transfer Ratio range: 1000% to 4000% @ 1mA
• Voltage - Output (Max): 200V
• Current - Output / Channel: 150mA
• Vce Saturation (Max): 1.2V
• Operating Temperature range: -25°C ~ 100°C
• Package / Case: 6-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in applications designed for the IS660SM.

Parameter Comparison

Engineering Selection Recommendations

The IS660X is a parametric equivalent to the IS660SM. Both parts are manufactured by Isocom Components 2004 LTD and share identical electrical and mechanical specifications. Both parts maintain Active product status and comply with ROHS3 and REACH requirements. Selection between these parts may be based on inventory availability or lead time considerations, as no technical differentiation exists between them for applications requiring 5300Vrms isolation with Darlington output in a 6-DIP through-hole package.

Frequently Asked Questions (FAQ)

Q: Can IS660X be used as a direct replacement for IS660SM?

A: Yes. The IS660X meets all parametric requirements of the IS660SM, including isolation voltage, current transfer ratio, output characteristics, and package specifications. Both parts are electrically and mechanically equivalent.

Q: Are there any differences in compliance or certifications between IS660SM and IS660X?

A: No. Both parts carry identical RoHS3 compliance status and REACH unaffected designation. Both are classified as Active products.

Q: What is the significance of the 6-DIP package specification?

A: The 6-DIP (0.300", 7.62mm) package defines the physical form factor and pin configuration. Both IS660SM and IS660X use this identical package, ensuring mechanical compatibility in PCB layouts and through-hole mounting applications.

Q: Are there any temperature or environmental limitations when substituting these parts?

A: Both parts operate across the same temperature range of -25°C to 100°C. No additional environmental limitations apply to substitution.

Q: What parameters must remain constant when selecting a substitute optoisolator?

A: Critical parameters include isolation voltage (5300Vrms), number of channels (1), output type (Darlington), current transfer ratio range (1000% to 4000% @ 1mA), maximum output voltage (200V), output current per channel (150mA), and package type (6-DIP through-hole).
