Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EL3H7(A)(EA)-VG are identified based on strict equivalence across the following critical parameters:

Isolation Voltage: 3750Vrms isolation rating is the primary electrical specification determining safe operation in high-voltage isolation applications.

Channel Configuration: Single channel (1 channel) output structure must be maintained.

Output Type & Ratings: Transistor output with maximum output voltage of 80V and maximum output current of 50mA per channel.

Current Transfer Ratio: Operating range of 80% to 160% @ 5mA input current defines the optical coupling efficiency.

Switching Characteristics: Rise and fall times of 5µs and 3µs respectively establish the frequency response capability.

Package Configuration: 4-SOIC (0.173", 4.40mm Width) surface mount package with 4-SSOP supplier device package designation.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating ensure regulatory and manufacturing process compatibility.

Substitute parts must match all parameters listed above without deviation. Parametric equivalents are identified from the same manufacturer base product series where all electrical and mechanical specifications are identical.
