Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISD201G is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 5300Vrms minimum
• Number of channels: 1 channel configuration
• Output type: Transistor output
• Maximum output voltage: 70V
• Maximum output current per channel: 50mA
• Current transfer ratio: 75% @ 10mA minimum
• Package type: 8-DIP (0.400", 10.16mm)
• Mounting type: Through Hole
• Operating temperature range: -25°C ~ 100°C
• RoHS compliance: ROHS3 Compliant

The ISD201XG meets all specified parameters and qualifies as a parametric equivalent within the ISD20 series.

Parameter Comparison

Engineering Selection Recommendations

Both ISD201G and ISD201XG are active production components manufactured by Isocom Components 2004 LTD with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and are suitable for applications requiring 5300Vrms isolation with single-channel transistor output in 8-DIP through-hole packages. Selection between these parts may be based on inventory availability, procurement lead times, or supply chain preferences, as they are parametrically equivalent.
