MOC3022SVM Optoisolator Equivalent & Substitute Parts

Part Overview

The MOC3022SVM is a 4170Vrms isolation optoisolator with triac output manufactured by onsemi in a 6-SMD surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The MOC3022SVM serves applications requiring galvanic isolation in triac-driven circuits with moderate isolation voltage requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC3022SVM is determined by the following critical parameters:

Primary Substitution Criteria:

• Output Type: Triac (mandatory match)
• Number of Channels: 1 (mandatory match)
• Package / Case: 6-SMD, Gull Wing (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Voltage - Isolation: Minimum 4170Vrms (equal or higher acceptable)
• Voltage - Off State: 400 V (mandatory match)

Acceptable Variation Parameters:

• Current - LED Trigger (Ift): Equal or lower values acceptable (lower trigger current reduces input drive requirements)
• Current - Hold (Ih): Higher values acceptable within circuit tolerance
• Current - DC Forward (If): Equal or lower values acceptable
• Operating Temperature: Equal or wider range acceptable

The MOC3022SR2M from onsemi provides a direct equivalent with identical electrical specifications and active product status. Lite-On Inc. MOC302x series parts (MOC3020S, MOC3021S, MOC3022S, MOC3023S) offer higher isolation voltage (5000Vrms) with compatible package and output characteristics, suitable for designs requiring enhanced isolation margin.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MOC3022SR2M

The MOC3022SR2M from onsemi is the direct functional equivalent of the MOC3022SVM. It maintains identical electrical specifications (4170Vrms isolation, 10mA trigger current, 100µA hold current) and identical package configuration. The MOC3022SR2M carries active product status and ROHS3 compliance, providing long-term supply assurance and regulatory alignment. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendation: Lite-On MOC302x Series

The Lite-On MOC3020S, MOC3021S, MOC3022S, and MOC3023S parts provide higher isolation voltage (5000Vrms) while maintaining compatible package, output type, and off-state voltage specifications. These parts are suitable for designs where enhanced isolation margin is acceptable or beneficial. Selection within this series depends on input drive current requirements:

• MOC3023S / MOC3023S-TA1: 5mA trigger current (lowest drive requirement)
• MOC3022S / MOC3022S-TA1: 10mA trigger current (matches MOC3022SVM specification)
• MOC3021S / MOC3021S-TA1: 15mA trigger current
• MOC3020S: 30mA trigger current (highest drive requirement)

All Lite-On parts feature ROHS3 compliance and active product status. Operating temperature range extends to 100°C, providing wider thermal margin compared to the MOC3022SVM specification of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can MOC3022SR2M directly replace MOC3022SVM without circuit modification?

A: Yes. The MOC3022SR2M maintains identical electrical specifications and package configuration. No circuit modifications are required for direct substitution.

Q: What is the key difference between MOC3022SVM and the Lite-On MOC302x series?

A: The primary difference is isolation voltage rating. The MOC3022SVM specifies 4170Vrms isolation, while Lite-On MOC302x parts specify 5000Vrms. All other critical parameters (output type, package, off-state voltage, channel count) remain compatible. The higher isolation voltage in Lite-On parts provides additional safety margin in high-voltage applications.

Q: Can I use MOC3023S instead of MOC3022S in the same circuit?

A: MOC3023S requires lower input trigger current (5mA maximum versus 10mA for MOC3022S). This is compatible with circuits designed for MOC3022S operation, as the lower trigger requirement reduces input drive demands. Circuit operation remains valid.

Q: Are packaging options interchangeable between onsemi and Lite-On parts?

A: Yes. Both onsemi MOC3022SR2M and all Lite-On MOC302x substitute parts use identical 6-SMD Gull Wing surface mount packaging. PCB footprints and reflow profiles are compatible.

Q: What is the significance of the -TA1 suffix in part numbers?

A: The -TA1 suffix indicates tape and reel packaging format (Cut Tape & Digi-Reel). Parts without this suffix are supplied in tube packaging. Electrical specifications and functionality are identical; the suffix reflects only packaging and delivery format.

Q: Which substitute part offers the best long-term availability?

A: MOC3022SR2M from onsemi carries active product status with established supply channels. Among Lite-On alternatives, MOC3023S-TA1 and MOC3022S-TA1 show the highest inventory levels (155,300 and 125,300 units respectively), indicating strong market availability.

Q: Do all substitute parts meet the same regulatory certifications as MOC3022SVM?

A: MOC3022SR2M maintains UL approval matching the original part. Lite-On MOC302x series parts carry broader certification coverage including CQC, CSA, TUV, UL, and VDE approvals, providing enhanced regulatory flexibility for international applications.
