Substitute Part Grouping Explanation

Substitution for the MOC217VM is determined by the following critical parameters that must be maintained or exceeded:

Package compatibility: 8-SOIC form factor with identical pinout
Isolation voltage: Minimum 2500Vrms
Output configuration: Transistor with base output
Single channel operation
DC input type
Maximum output voltage: 30V
Maximum output current: 150mA per channel
Operating temperature range: -40°C to 100°C minimum

Substitute parts are classified into two categories:

Direct Substitutes maintain all electrical and mechanical specifications within the same isolation voltage class (2500Vrms).

Similar Substitutes provide higher isolation voltage ratings (4000Vrms) with compatible package and output configurations, suitable for applications where enhanced isolation margin is acceptable.

Engineering Selection Recommendations

MOC217R2VM (Direct Substitute)

The MOC217R2VM from Fairchild Semiconductor is the primary direct substitute for the obsolete MOC217VM. Both components maintain identical isolation voltage (2500Vrms), package configuration (8-SOIC), and output specifications. The MOC217R2VM is currently in active production status, ensuring long-term availability. The primary difference is the current transfer ratio specification point (100% @ 10mA versus 100% @ 1mA), which represents a more conservative specification for the substitute part. This component is suitable for direct replacement in existing designs without circuit modification.

IL215AT and IL216AT (Similar Substitutes)

The IL215AT and IL216AT from Vishay Semiconductor Opto Division provide higher isolation voltage ratings (4000Vrms) compared to the MOC217VM (2500Vrms). Both maintain the 8-SOIC package and transistor with base output configuration. These components are actively produced and RoHS3 compliant. The IL215AT specifies 20% current transfer ratio minimum at 1mA, while the IL216AT specifies 50% at 1mA, offering improved performance characteristics. The faster switching times (3µs on/off versus 7.5µs/5.7µs) and extended operating temperature range (-55°C to 100°C) provide additional design margin. These substitutes are appropriate for applications where enhanced isolation voltage capability is beneficial or where improved switching performance is required.

Frequently Asked Questions (FAQ)

Q: Can MOC217R2VM be used as a direct replacement for MOC217VM?

A: Yes. The MOC217R2VM maintains all critical electrical and mechanical parameters of the MOC217VM, including 2500Vrms isolation voltage, 8-SOIC package, transistor with base output, 30V maximum output voltage, and 150mA output current capability. The component is pin-compatible and requires no circuit modifications.

Q: What is the primary difference between MOC217R2VM and the IL215AT/IL216AT substitutes?

A: The MOC217R2VM is a direct substitute maintaining 2500Vrms isolation voltage. The IL215AT and IL216AT provide higher isolation voltage (4000Vrms) with faster switching characteristics (3µs versus 7.5µs turn-on time). Selection depends on whether the application requires the higher isolation margin or improved switching performance.

Q: Are IL215AT and IL216AT interchangeable with each other?

A: Both components share identical package, isolation voltage, output configuration, and operating temperature range. The primary difference is the current transfer ratio specification: IL215AT specifies 20% minimum at 1mA, while IL216AT specifies 50% minimum at 1mA. Selection should be based on the specific current transfer ratio requirement of the application.

Q: What packaging options are available for these substitutes?

A: MOC217R2VM is supplied in Bulk packaging. IL215AT is supplied in Tape & Reel (TR) format. IL216AT is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection should align with production volume and assembly requirements.

Q: Are these substitute parts RoHS compliant?

A: IL215AT and IL216AT are RoHS3 compliant. MOC217R2VM compliance information is not specified in the provided data. Verify RoHS compliance requirements with the component supplier for your specific application.

Q: What is the moisture sensitivity level for these components?

A: MOC217VM, IL215AT, and IL216AT all specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
