Substitute Part Grouping Explanation

Substitution of the HCPL-2502#020 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Configuration: Transistor with Base (mandatory match)
• Current Transfer Ratio: 15% to 22% @ 16mA (mandatory match)
• Switching Times: Turn On 200ns, Turn Off 600ns (mandatory match)
• Package Type: 8-DIP through-hole (mandatory match)
• Input Type: DC (mandatory match)
• Output Voltage Rating: 20V maximum (mandatory match)
• Output Current: 8mA per channel (mandatory match)

The HCPL-2502-020E is a direct manufacturer equivalent that maintains identical electrical performance and mechanical compatibility with the discontinued HCPL-2502#020.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2502-020E is the direct substitute for the discontinued HCPL-2502#020. Both parts are manufactured by Broadcom Limited and maintain identical electrical specifications and mechanical compatibility.

The HCPL-2502-020E offers the advantage of active product status with current availability and ROHS3 compliance, whereas the original HCPL-2502#020 is discontinued and RoHS non-compliant. For new designs and production continuity, the HCPL-2502-020E is the appropriate selection.

Both parts share identical isolation voltage, channel configuration, current transfer ratio, switching characteristics, and package specifications, ensuring direct pin-for-pin and functional compatibility in existing circuit designs.
