MOC206VM Equivalent & Substitute Parts

Part Overview

The MOC206VM is an optoisolator transistor with base output manufactured by onsemi, rated for 2500Vrms isolation voltage in an 8-SOIC surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part provides galvanic isolation with a single transistor output channel suitable for DC input applications requiring moderate isolation ratings and switching speeds.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC206VM is determined by the following critical parameters:

• Package compatibility: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Output configuration: Transistor with base output topology
• Isolation voltage: Minimum 2500Vrms (higher ratings are acceptable)
• Input type: DC input
• Output voltage rating: Maximum 30V or higher
• Saturation voltage: 400mV or lower
• Operating temperature range: Must encompass or exceed -40°C to 100°C
• Mounting type: Surface mount

The substitute parts identified (IL215AT and IL216AT) meet these criteria with enhanced isolation voltage ratings of 4000Vrms, providing superior performance margins while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both IL215AT and IL216AT are active, production-grade alternatives to the obsolete MOC206VM. Selection between these substitutes should be based on the following factors:

IL216AT offers a higher minimum current transfer ratio (50% @ 1mA) compared to IL215AT (20% @ 1mA), providing improved gain characteristics for applications requiring consistent switching performance across input current variations.

IL215AT is suitable for applications where the lower minimum current transfer ratio is acceptable and cost optimization is a priority.

Both substitutes provide:

• Enhanced isolation voltage (4000Vrms vs. 2500Vrms)
• Faster switching times (3µs vs. 7.5µs turn-on)
• Extended operating temperature range (-55°C to 100°C vs. -40°C to 100°C)
• RoHS3 compliance for regulatory requirements
• Identical package footprint and electrical interface compatibility

Frequently Asked Questions (FAQ)

Q: Can IL215AT or IL216AT be used as direct replacements for MOC206VM?

A: Yes, both parts are electrically and mechanically compatible. The 8-SOIC package footprint is identical, and all critical electrical parameters (output voltage, saturation voltage, output current capability) are equivalent or superior. The higher isolation voltage rating provides additional safety margin.

Q: What is the difference between IL215AT and IL216AT?

A: The primary difference is the minimum current transfer ratio specification. IL216AT specifies 50% @ 1mA, while IL215AT specifies 20% @ 1mA. This affects the input current required to achieve reliable switching. IL216AT is preferred for applications with tighter input current budgets.

Q: Are there any temperature range considerations?

A: The substitute parts operate from -55°C to 100°C, which exceeds the MOC206VM range of -40°C to 100°C. This provides additional margin for low-temperature applications.

Q: Do the substitutes have different packaging options?

A: IL215AT is supplied in Tape & Reel (TR) format, while IL216AT is supplied in Cut Tape (CT) & Digi-Reel® format. Both are 8-SOIC surface mount packages with identical electrical and mechanical specifications.

Q: Are there compliance or regulatory differences?

A: Both IL215AT and IL216AT are RoHS3 compliant, whereas MOC206VM is REACH Unaffected. For new designs, the RoHS3 compliance of the substitutes aligns with current regulatory requirements.
