MOC207R1VM Equivalent & Substitute Parts

Part Overview

The MOC207R1VM is an optoisolator transistor with base output manufactured by onsemi, designed for 2500Vrms isolation applications in 8-SOIC surface mount packaging. This component integrates a photodiode input stage with a transistor output stage including base connection, enabling flexible circuit design in isolated switching applications.

The MOC207R1VM is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this optoisolator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC207R1VM are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 2500Vrms isolation voltage, 100-200% current transfer ratio at 10mA, 7.5µs/5.7µs turn-on/turn-off times, 30V maximum output voltage, 150mA output current, and 8-SOIC package form factor. These parts differ only in product status (active vs. obsolete) and packaging format (tape & reel vs. cut tape).

Similar Substitutes share the same package, output topology (transistor with base), and general application class but operate at higher isolation voltage (4000Vrms vs. 2500Vrms) and exhibit different current transfer ratio specifications. These parts are suitable for applications where increased isolation margin is acceptable and the lower current transfer ratio does not compromise circuit performance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

MOC207R2M and MOC207R2VM are direct parametric equivalents to the MOC207R1VM. Both maintain identical electrical specifications and 8-SOIC package compatibility. Selection between these two should be based on packaging requirements: MOC207R2M is supplied in cut tape format, while MOC207R2VM is supplied in tape & reel format. Both parts carry active product status and ROHS3 compliance, providing superior supply chain availability compared to the obsolete MOC207R1VM.

For Higher Isolation Margin Applications:

IL215AT and IL216AT are active, ROHS3-compliant alternatives from Vishay Semiconductor Opto Division. These parts provide 4000Vrms isolation voltage, exceeding the MOC207R1VM specification by 1500Vrms. The extended operating temperature range (-55°C to 100°C vs. -40°C to 100°C) supports broader environmental applications. Current transfer ratio specifications differ significantly; IL215AT specifies 20% minimum at 1mA, while IL216AT specifies 50% minimum at 1mA. These parts are suitable only when circuit design accommodates the lower current transfer ratio specifications and the higher isolation voltage does not create design conflicts.

Frequently Asked Questions (FAQ)

Q: Can MOC207R2M or MOC207R2VM be used as direct replacements for MOC207R1VM?

A: Yes. MOC207R2M and MOC207R2VM are parametric equivalents with identical electrical specifications, including isolation voltage (2500Vrms), current transfer ratio (100-200% @ 10mA), switching times, and output characteristics. The only differences are packaging format and active product status. PCB layout and circuit design require no modification.

Q: What is the difference between MOC207R2M and MOC207R2VM?

A: Both parts are electrically identical. MOC207R2M is supplied in cut tape (CT) & Digi-Reel format with 32,100 pcs in stock. MOC207R2VM is supplied in tape & reel (TR) format with 3,524 pcs in stock. Selection depends on assembly equipment compatibility and volume requirements.

Q: Can IL215AT or IL216AT replace MOC207R1VM in existing designs?

A: IL215AT and IL216AT share the same 8-SOIC package and transistor-with-base output topology but operate at 4000Vrms isolation voltage and exhibit lower current transfer ratios (20% and 50% minimum, respectively, vs. 100% minimum for MOC207R1VM). These parts are suitable only if circuit design has been verified to function with the lower current transfer ratio and if the higher isolation voltage does not conflict with application requirements.

Q: What is the significance of the current transfer ratio difference between MOC207R1VM and IL215AT/IL216AT?

A: Current transfer ratio defines the ratio of output collector current to input LED current. MOC207R1VM guarantees 100% minimum at 10mA input, while IL215AT guarantees only 20% minimum at 1mA input. This means IL215AT requires higher input current to achieve equivalent output current. Circuit designs relying on specific current transfer ratio values must be re-evaluated before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: MOC207R2M and MOC207R2VM are ROHS3 compliant. IL215AT and IL216AT are ROHS3 compliant. The original MOC207R1VM does not specify RoHS status. If RoHS compliance is a design requirement, MOC207R2M, MOC207R2VM, IL215AT, or IL216AT are suitable selections.

Q: What is the operating temperature range difference?

A: MOC207R1VM, MOC207R2M, and MOC207R2VM operate from -40°C to 100°C. IL215AT and IL216AT operate from -55°C to 100°C, providing 15°C additional low-temperature margin. This extended range is beneficial for applications requiring operation in cold environments.

Q: Can I mix different substitute parts in the same production run?

A: No. While MOC207R2M and MOC207R2VM are parametrically identical, mixing different part numbers in a single production run introduces supply chain complexity and potential traceability issues. Standardize on a single part number per design revision. IL215AT and IL216AT should not be mixed with MOC207R2M/MOC207R2VM due to different electrical specifications.
