Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFH620A-2 is determined by strict equivalence across the following critical parameters:

• Single channel configuration (Number of Channels = 1)
• Isolation voltage rating of 7.5Vpk
• Current transfer ratio range: 63% to 200% @ 10mA
• Transistor output type with maximum output voltage of 70V
• Output current capability of 50mA per channel
• Rise and fall time specifications of 4µs and 3µs respectively
• AC and DC input compatibility
• 4-DIP through-hole package format (0.300", 7.62mm)
• Operating temperature range of -30°C to 100°C
• ROHS3 compliance and active product status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations
