Substitute Part Grouping Explanation

Substitution eligibility for the ISP824 is determined by strict parametric equivalence across the following critical specifications:

• Number of Channels: 2
• Voltage - Isolation: 7.5Vpk
• Current Transfer Ratio range: 20% (Min) to 300% (Max) @ 1mA
• Rise / Fall Time: 4µs, 3µs
• Input Type: AC, DC
• Output Type: Transistor
• Voltage - Output (Max): 35V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Operating Temperature: -30°C ~ 100°C
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The ISP824X meets all parametric requirements and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ISP824 and ISP824X are active production components manufactured by Isocom Components 2004 LTD with identical electrical and mechanical specifications. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Selection between these parts should be based on inventory availability and procurement lead times. The ISP824 offers higher stock levels at 4200 units, while the ISP824X provides an alternative source with 1048 units available. Both parts are suitable for direct substitution in through-hole PCB applications requiring dual-channel optoisolation at 7.5Vpk with transistor output.

Frequently Asked Questions (FAQ)

Q: Can ISP824X be used as a direct replacement for ISP824?

A: Yes. The ISP824X meets all parametric requirements of the ISP824, including isolation voltage, current transfer ratio, output current, switching times, and package specifications. Both parts are electrically and mechanically equivalent.

Q: Are there any differences in compliance or certifications between ISP824 and ISP824X?

A: No. Both parts carry identical RoHS3 compliance status, REACH unaffected designation, and MSL Level 1 rating.

Q: What is the significance of the 8-DIP package specification?

A: The 8-DIP (0.300", 7.62mm) package specifies a through-hole dual inline package with 0.3-inch row spacing and 7.62mm pitch. Both ISP824 and ISP824X use this identical package, ensuring PCB footprint compatibility and interchangeability.

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

A: Yes. Both ISP824 and ISP824X support AC and DC input types, providing flexibility for various circuit configurations.

Q: What is the maximum output current per channel?

A: Both parts deliver 50mA maximum output current per channel, with a maximum output voltage of 35V and Vce saturation of 200mV.
