Substitute Part Grouping Explanation
The ACPL-244-560E has one identified substitute: ACPL-244-500E. This substitution is valid based on the following criteria:
Both parts share identical electrical specifications across all critical parameters: 4-channel configuration, 3000Vrms isolation voltage, 20% minimum and 400% maximum current transfer ratio at 1mA, 3µs turn-on and turn-off times, 2µs and 3µs rise and fall times respectively, 80V maximum output voltage, and 50mA output current per channel. Both components operate across the same temperature range (-55°C to 110°C) and are housed in the 16-SOIC package with identical physical dimensions. Compliance certifications including ROHS3, moisture sensitivity level 1, and REACH unaffected status are equivalent. Both parts are manufactured by Broadcom Limited and maintain active product status.
