SFH620A-2G Equivalent & Substitute Parts

Part Overview

The SFH620A-2G is a single-channel optoisolator with transistor output, designed for AC and DC input applications requiring galvanic isolation. This component operates at 7.5Vpk isolation voltage and delivers up to 50mA output current per channel in a 4-DIP through-hole package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when identical electrical and mechanical parameters are maintained across the same product series.

Key Parameters

Substitute Part Grouping Explanation

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

• Number of channels: 1
• Isolation voltage: 7.5Vpk
• Current transfer ratio range: 63% to 200% @ 10mA
• Output type: Transistor
• Maximum output voltage: 70V
• Maximum output current per channel: 50mA
• Package type: 4-DIP through-hole
• Operating temperature range: -30°C ~ 100°C
• Compliance certifications: RoHS3, REACH Unaffected

Parts meeting all these criteria within the SFH620A-2 series are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SFH620A-2XG is a direct parametric equivalent to the SFH620A-2G. Both parts are manufactured by Isocom Components 2004 LTD within the same SFH620A-2 series and maintain identical electrical and mechanical specifications. Both parts carry active product status, full RoHS3 compliance, and REACH Unaffected designation. Selection between these parts may be based on inventory availability or supplier sourcing requirements, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can SFH620A-2XG replace SFH620A-2G in existing designs?

A: Yes. Both parts are parametric equivalents with identical isolation voltage, current transfer ratio, output characteristics, and package specifications. Direct substitution is supported without circuit modification.

Q: Are there differences in isolation performance between these parts?

A: No. Both parts maintain 7.5Vpk isolation voltage and identical current transfer ratio specifications (63% to 200% @ 10mA).

Q: Do both parts support the same input types?

A: Yes. Both SFH620A-2G and SFH620A-2XG accept AC and DC input signals.

Q: Are the package dimensions identical?
