Substitute Part Grouping Explanation

Substitution of the H11L3TM is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 4170Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Configuration: Open Collector (mandatory match)
• Output Current Rating: 50 mA per channel (mandatory match)
• Data Rate: 1MHz (mandatory match)
• Package Type: 6-DIP through-hole (mandatory match)
• Input Type: DC (mandatory match)
• Supply Voltage Range: 3V ~ 15V (mandatory match)
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)

The H11L3TVM qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The H11L3TVM is the direct equivalent substitute for the H11L3TM. Both components share identical electrical and mechanical specifications, including isolation voltage, channel configuration, output type, current rating, data rate, timing characteristics, and package dimensions.

The H11L3TVM offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the H11L3TVM carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and production environments where RoHS compliance is mandated.

For applications currently using the obsolete H11L3TM, direct substitution with the H11L3TVM requires no circuit modifications or design changes. Pin-to-pin compatibility and functional equivalence are guaranteed across all specified operating conditions.
