Substitute Part Grouping Explanation

Substitute parts for the ISP824SM are identified based on strict equivalence across all critical parameters. The substitution logic requires matching of the following key criteria:

  • Dual-channel configuration (Number of Channels = 2)
  • Isolation voltage specification (7.5Vpk)
  • Current transfer ratio range (20% to 300% @ 1mA)
  • Transistor output type with 50mA per-channel current rating
  • Maximum output voltage of 35V
  • Vce saturation specification of 200mV maximum
  • Operating temperature range of -30°C to 100°C
  • Surface-mount 8-SMD Gull Wing package
  • ROHS3 compliance and MSL Level 1 rating

Only parts meeting all these parameters are classified as parametric equivalents. Variations in any single parameter disqualify a part from substitution eligibility.

Engineering Selection Recommendations

The ISP824XSM is a direct parametric equivalent to the ISP824SM. Both parts are manufactured by Isocom Components 2004 LTD within the ISP824 series and maintain identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: ISP824SM has 877 units in stock, while ISP824XSM has 822 units in stock. Both parts carry active product status, ROHS3 compliance, and REACH unaffected designation, making either suitable for applications requiring dual-channel optoisolation with the specified performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ISP824XSM be used as a direct replacement for ISP824SM?

A: Yes. The ISP824XSM meets all electrical and mechanical parameters of the ISP824SM, including isolation voltage, current transfer ratio, output current rating, package type, and operating temperature range. Both parts are from the same manufacturer and series.

Q: Are there any differences in compliance or certification between these parts?

A: No. Both ISP824SM and ISP824XSM carry identical ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating.

Q: What determines if a part can substitute for the ISP824SM?

A: Substitution requires matching all critical parameters: dual-channel configuration, 7.5Vpk isolation voltage, 20-300% current transfer ratio, 50mA output current per channel, 35V maximum output voltage, 200mV Vce saturation, -30°C to 100°C operating temperature, and 8-SMD Gull Wing surface-mount package.

Q: Does the package designation affect substitution eligibility?

A: Yes. The 8-SMD Gull Wing package is a mandatory matching criterion. Parts with different package types or pin configurations are not substitutes.

Q: Can these parts be used in both AC and DC input applications?

A: Yes. Both ISP824SM and ISP824XSM support AC and DC input types, providing flexibility in circuit design.
