Substitute Part Grouping Explanation

Substitute parts for the IS205SM optoisolator are identified based on strict equivalence across the following critical parameters:

• Isolation voltage rating: 5300Vrms
• Single channel configuration
• Transistor output topology
• Maximum output voltage: 30V
• Maximum output current per channel: 50mA
• Current transfer ratio minimum: 100% @ 10mA
• Switching characteristics: 2µs rise and fall times
• Output saturation voltage: 400mV maximum
• Operating temperature range: -55°C to 100°C
• Surface mount package: 6-SMD, Gull Wing
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

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

Parameter Comparison

Engineering Selection Recommendations

The IS205XSM is a direct parametric equivalent to the IS205SM. Both components are manufactured by Isocom Components 2004 LTD within the IS205 series and maintain identical electrical and mechanical specifications. Both parts carry Active product status, ensuring continued availability and support. Regulatory compliance is equivalent across both parts: ROHS3 Compliant and REACH Unaffected. Selection between IS205SM and IS205XSM may be based on inventory availability, lead time, or procurement source, as no technical differentiation exists between the two parts.

Frequently Asked Questions (FAQ)

Q: Can IS205XSM replace IS205SM in existing designs?

A: Yes. IS205XSM is a parametric equivalent with identical isolation voltage (5300Vrms), output characteristics (30V maximum, 50mA per channel), switching performance (2µs rise/fall times), and package configuration (6-SMD, Gull Wing). No circuit modifications are required.
