Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EL3H7(A)(TA)-VG are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that define functional interchangeability:

Electrical Equivalence Criteria:

• Voltage - Isolation: 3750Vrms
• Number of Channels: 1
• Current Transfer Ratio range: 80% to 160% @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Operating Temperature range: -55°C ~ 110°C

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: 4-SOIC (0.173", 4.40mm Width)
• Supplier Device Package: 4-SSOP

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all criteria above are classified as parametric equivalents and direct substitutes. Differences in tape configuration (TA versus EA designations) and reel specifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The EL3H7(A)(EA)-G is a direct parametric equivalent to the EL3H7(A)(TA)-VG. Both components are manufactured by Everlight Electronics Co Ltd and maintain identical electrical performance specifications, mechanical dimensions, and compliance certifications.
