MCT6 Optoisolator Equivalent & Substitute Parts

Part Overview

The MCT6 is a dual-channel optoisolator with transistor output, rated for 5300Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between input and output circuits with DC input control and transistor switching capability. The MCT6 is classified as Active product status with 174,300 units in current inventory. Alternative part numbers may be required due to packaging constraints, lead time availability, or specific application mounting requirements while maintaining electrical and functional equivalence.

Substitute Part Grouping Explanation

Substitution eligibility for the MCT6 is determined by strict equivalence across the following critical parameters:

  • Number of Channels: 2 channels required
  • Voltage - Isolation: 5300Vrms minimum
  • Current Transfer Ratio: 20% @ 10mA minimum
  • Output Type: Transistor output configuration
  • Voltage - Output (Max): 30V
  • Current - Output / Channel: 50mA
  • Vce Saturation (Max): 400mV
  • Operating Temperature Range: -25°C ~ 100°C
  • Input Type: DC
  • Mounting Type: Through Hole

The MCT6X meets all electrical and functional parameters required for direct substitution. Both parts share identical isolation voltage, channel count, output current capability, and thermal operating range. Packaging differences exist but do not affect electrical performance or functional compatibility in through-hole applications.

Engineering Selection Recommendations

Both MCT6 and MCT6X are Active product status components manufactured by Isocom Components and maintain full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on:

  • PCB layout and board space availability for through-hole mounting
  • Supplier inventory and lead time requirements
  • Packaging format preference (MCT6 standard packaging vs. MCT6X tube packaging)
  • Cost considerations based on current market availability

All electrical parameters, isolation ratings, and functional characteristics are identical. Both components are suitable for direct substitution in applications requiring dual-channel optoisolation at 5300Vrms with transistor output switching.
