MOC205R1VM Equivalent & Substitute Parts

Part Overview

The MOC205R1VM is an optoisolator transistor with base output manufactured by onsemi, featuring 2500Vrms isolation voltage in an 8-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The MOC205R1VM provides galvanic isolation with a single transistor output channel suitable for DC input applications requiring moderate current switching capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC205R1VM are classified into two categories based on electrical parameter compatibility:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 2500Vrms isolation voltage, 40-80% current transfer ratio at 10mA, 150mA output current, 30V maximum output voltage, and 400mV Vce saturation. These parts differ only in product status (active vs. obsolete) and packaging format (tape & reel vs. cut tape). Parametric equivalents are direct functional replacements with no design modifications required.

Similar Parts share the same package footprint (8-SOIC) and output type (transistor with base) but operate at higher isolation voltage (4000Vrms) and feature different current transfer ratio specifications. These parts are suitable for applications where increased isolation margin is acceptable and where the different electrical characteristics do not conflict with circuit requirements.

Key parameters determining substitution eligibility:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Output Type: Transistor with Base
• Voltage - Isolation: 2500Vrms (parametric equivalents) or 4000Vrms (similar parts)
• Current Transfer Ratio: 40-80% @ 10mA (parametric equivalents) or alternative specifications (similar parts)
• Vce Saturation (Max): 400mV
• Operating Temperature Range: -40°C ~ 100°C minimum

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

MOC205R2M and MOC205R2VM are active production equivalents of the obsolete MOC205R1VM. Both parts maintain identical electrical specifications and package configuration. MOC205R2VM is preferred for high-volume applications due to superior inventory availability (180,000 pcs) and tape & reel packaging format. MOC205R2M is suitable for lower-volume requirements with cut tape & digi-reel packaging (3,800 pcs available). Both parts are ROHS3 compliant, addressing regulatory requirements not specified for the original part.

For Applications Requiring Enhanced Isolation:

IL215AT and IL216AT are Vishay Semiconductor alternatives offering 4000Vrms isolation voltage, providing 60% additional isolation margin compared to the MOC205R1VM. These parts maintain compatible package footprint and output type. IL215AT features 20% minimum current transfer ratio at 1mA, while IL216AT specifies 50% minimum at 1mA. Both parts support extended operating temperature range (-55°C to 100°C) and are ROHS3 compliant. Selection between IL215AT and IL216AT depends on current transfer ratio requirements and packaging preference (tape & reel vs. cut tape & digi-reel).

Frequently Asked Questions (FAQ)

Q: Can MOC205R2M and MOC205R2VM be used interchangeably with MOC205R1VM?

A: Yes. MOC205R2M and MOC205R2VM are parametric equivalents with identical electrical specifications. The primary difference is packaging format: MOC205R2VM uses tape & reel packaging suitable for automated assembly, while MOC205R2M uses cut tape & digi-reel format. Both are active production parts replacing the obsolete MOC205R1VM.

Q: What are the differences between IL215AT and IL216AT?

A: Both parts provide 4000Vrms isolation in 8-SOIC packages. IL215AT specifies 20% minimum current transfer ratio at 1mA, while IL216AT specifies 50% minimum at 1mA. IL215AT is supplied in tape & reel packaging, and IL216AT in cut tape & digi-reel format. Selection depends on current transfer ratio requirements and assembly process compatibility.

Q: Are the Vishay IL215AT and IL216AT direct replacements for MOC205R1VM?

A: IL215AT and IL216AT are compatible alternatives rather than direct replacements. They maintain the same 8-SOIC package footprint and transistor-with-base output type, but operate at 4000Vrms isolation voltage compared to 2500Vrms. These parts are suitable when increased isolation margin is acceptable and circuit design does not depend on the specific 2500Vrms isolation rating.

Q: What compliance certifications apply to substitute parts?

A: MOC205R2M and MOC205R2VM are ROHS3 compliant. IL215AT and IL216AT are ROHS3 compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating. All parts carry EAR99 ECCN classification and HTSUS code 8541.49.8000.

Q: Which substitute part should be selected for new designs?

A: For direct electrical compatibility, select MOC205R2VM due to active production status and high inventory availability. For applications requiring enhanced isolation voltage, select IL216AT (50% CTR minimum) or IL215AT (20% CTR minimum) based on current transfer ratio requirements. All three options are active production parts suitable for new design implementation.
