MOC211R1VM Equivalent & Substitute Parts

Part Overview

The MOC211R1VM is an optoisolator transistor with base output manufactured by onsemi, providing 2500Vrms isolation in an 8-SOIC surface mount package. This component integrates a photodiode input stage with a transistor output stage including base connection, enabling isolated signal transmission in industrial and consumer applications. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC211R1VM are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents (Parametric Match): Parts that maintain identical electrical specifications across all critical parameters including isolation voltage (2500Vrms), current transfer ratio (20% @ 10mA), output voltage rating (30V), output current (150mA), and package form factor (8-SOIC). These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Parts (Enhanced Specifications): Parts that share the same package, output type (transistor with base), and mounting technology but feature higher isolation voltage ratings (4000Vrms) or different current transfer ratio specifications. These parts require design review to confirm compatibility with the application's isolation and performance requirements.

The substitution logic is based strictly on:

• Voltage - Isolation rating
• Current Transfer Ratio (Min)
• Output voltage and current ratings
• Package / Case form factor
• Output Type configuration
• Operating temperature range

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

MOC211VM, MOC211R2M, and MOC211R2VM are direct parametric equivalents to the MOC211R1VM. All three maintain the 2500Vrms isolation voltage, 20% current transfer ratio at 10mA, 30V output voltage, and 150mA output current specifications. MOC211R2M and MOC211R2VM are preferred for new designs due to active product status and ROHS3 compliance where applicable. MOC211VM remains available as an alternative from Fairchild Semiconductor.

For Enhanced Isolation Applications:

IL215AT and IL216AT provide 4000Vrms isolation voltage, exceeding the MOC211R1VM specification by 60%. These parts are suitable for applications requiring higher isolation margins. IL216AT offers 50% current transfer ratio at 1mA, providing superior input sensitivity compared to the 20% specification of the MOC211R1VM. Both Vishay parts maintain the 8-SOIC package and are ROHS3 compliant with extended operating temperature range (-55°C to 100°C).

Compliance Considerations:

All active substitute parts carry REACH Unaffected status and EAR99 ECCN classification matching the original part. MOC211R2M, MOC211R2VM, IL215AT, and IL216AT are ROHS3 compliant, supporting environmental compliance requirements for new production.

Frequently Asked Questions (FAQ)

Q: Can MOC211VM be used as a direct replacement for MOC211R1VM?

A: Yes. MOC211VM is a direct parametric equivalent with identical isolation voltage (2500Vrms), current transfer ratio (20% @ 10mA), output ratings (30V, 150mA), and 8-SOIC package. The primary difference is manufacturer (Fairchild Semiconductor vs. onsemi) and packaging format (Bulk vs. Tape & Reel).

Q: What is the difference between MOC211R2M and MOC211R2VM?

A: Both parts are parametric equivalents with identical electrical specifications. MOC211R2M is supplied in Tape & Reel packaging, while MOC211R2VM is supplied in Bulk packaging. MOC211R2M is ROHS3 compliant; MOC211R2VM RoHS status is not applicable. Select based on procurement and assembly requirements.

Q: Can IL215AT or IL216AT replace MOC211R1VM in existing designs?

A: IL215AT and IL216AT are compatible at the package and pin level but feature 4000Vrms isolation voltage versus the 2500Vrms of MOC211R1VM. These parts are suitable for applications where higher isolation voltage provides design margin. IL216AT offers higher current transfer ratio (50% @ 1mA) compared to MOC211R1VM (20% @ 10mA), requiring input circuit evaluation.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All listed substitute parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical and electrical compatibility without PCB redesign.

Q: Which substitute part is recommended for new designs?

A: MOC211R2M is recommended for new designs. It maintains full parametric equivalence to MOC211R1VM, carries active product status, is ROHS3 compliant, and is available in standard Tape & Reel packaging for automated assembly.

Q: What is the operating temperature range difference between MOC211R1VM and IL215AT/IL216AT?

A: MOC211R1VM operates from -40°C to 100°C. IL215AT and IL216AT extend the lower temperature limit to -55°C, providing wider operating range for applications in extreme cold environments.
