Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—ISP847XC, ISP847XCG, and ISP847XCSM—are parametrically equivalent to the ISP847C and maintain Active product status. Each part carries RoHS3 compliance certification and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. Selection among these equivalents may be based on inventory availability and packaging specifications, as all electrical and mechanical parameters are identical. The through-hole 16-DIP package format ensures compatibility with existing PCB layouts designed for the ISP847C.

Frequently Asked Questions (FAQ)

Q: Can ISP847XC, ISP847XCG, and ISP847XCSM be used interchangeably with ISP847C?

A: Yes. All parts share identical electrical specifications including isolation voltage (5300Vrms), channel count (4), current transfer ratio (200–400% @ 5mA), output current capability (50mA per channel), and switching characteristics (4µs rise, 3µs fall time). The 16-DIP through-hole package is identical across all variants, confirming direct pin-for-pin compatibility.

Q: What determines substitution eligibility for ISP847 series optoisolators?

A: Substitution is based on matching the following parameters: number of channels, isolation voltage rating, current transfer ratio range, maximum output voltage, output current per channel, saturation voltage, switching speed, operating temperature range, and package format. All listed substitutes maintain these specifications.

Q: Are there any compliance differences between ISP847C and its substitutes?

A: No. All parts are RoHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. Moisture sensitivity level is 1 (Unlimited) for all variants.

Q: What is the significance of the different part number suffixes (C, XC, XCG, XCSM)?

A: The suffixes indicate manufacturing or packaging variants within the ISP847 series. Despite these designations, all variants maintain identical electrical performance and mechanical compatibility, enabling direct substitution based on the provided specifications.

Q: Can ISP847C be used in applications requiring high-speed switching?

A: The specified rise and fall times (4µs and 3µs respectively) define the switching performance. Applications requiring faster switching should verify compatibility with these timing specifications before selection.
