Substitute Part Grouping Explanation

All substitute parts within the ISP847 series maintain identical electrical and mechanical specifications as the main part number ISP847. Substitution is based on strict parameter equivalence across the following critical criteria:

Isolation voltage: 5300Vrms (all variants)
Channel count: 4 channels (all variants)
Output type: Transistor with identical current and voltage ratings
Current transfer ratio range: 50% to 600% @ 5mA (all variants)
Package: 16-DIP through-hole form factor (all variants)
Operating temperature range: -30°C to 100°C (all variants)
Compliance: ROHS3 and REACH unaffected (all variants)

The substitute part numbers ISP847X, ISP847XG, ISP847XGR, ISP847XGRG, and ISP847XGRSM represent manufacturing variants and packaging designations within the ISP847 product family. These variants are electrically and mechanically interchangeable with the main part number ISP847.
