MOC3022M Equivalent & Substitute Parts

Part Overview

The MOC3022M is an optoisolator with triac output manufactured by Lite-On Inc., designed for galvanic isolation in AC switching applications. This component features 5000Vrms isolation voltage, single-channel triac output, and 6-DIP through-hole packaging. The part is active in production with full RoHS3 compliance and multiple international approvals (CQC, CSA, TUV, UL, VDE). Substitute parts are identified based on functional equivalence within the MOC302 series, maintaining core isolation and switching characteristics while accommodating variations in electrical parameters and packaging specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MOC302 series is determined by the following criteria:

Primary Compatibility Factors:

• Output type: Triac (all candidates match)
• Number of channels: Single channel (all candidates match)
• Voltage - Off State: 400 V (all candidates match)
• Mounting type: Through Hole (all candidates match)
• Base product number: MOC302 (all candidates match)

Variable Parameters Affecting Substitution:

• Voltage - Isolation: Ranges from 4170Vrms to 5000Vrms
• Current - LED Trigger (Ift): Ranges from 5mA to 30mA
• Current - Hold (Ih): Ranges from 100µA to 250µA
• Current - DC Forward (If): Ranges from 50mA to 60mA
• Operating Temperature: Ranges from -40°C to 85°C or 100°C
• Package dimensions: 6-DIP with 0.300" (7.62mm) or 0.400" (10.16mm) pitch

All substitute parts maintain the MOC302 series designation and share the same functional architecture, enabling direct substitution where application requirements permit tolerance of parameter variations.

Parameter Comparison

Engineering Selection Recommendations

MOC3022M (onsemi, Tube packaging) - Direct functional equivalent with identical isolation voltage (5000Vrms), LED trigger current (10mA), and package pitch (0.300", 7.62mm). Maintains RoHS3 compliance and UL approval. Suitable for applications requiring the original specification without modification.

MOC3022TVM (onsemi, Tube packaging) - Functionally equivalent with matching LED trigger current (10mA) and isolation voltage (4170Vrms). Package pitch differs at 0.400" (10.16mm). RoHS3 compliant with IEC/EN/DIN and UL approvals. Acceptable where PCB layout accommodates wider DIP pitch.

MOC3023TVM (onsemi, Tube packaging) - Lowest LED trigger current (5mA) within the series, reducing input drive requirements. Isolation voltage 4170Vrms. Package pitch 0.400" (10.16mm). RoHS3 compliant with IEC/EN/DIN and UL approvals. Suitable for low-power input circuits.

MOC3020TVM (onsemi, Tube packaging) - Highest LED trigger current (30mA) in the substitute group. Isolation voltage 4170Vrms. Package pitch 0.400" (10.16mm). RoHS3 compliant with IEC/EN/DIN and UL approvals. Applicable where higher input drive capability is available.

MOC3021TVM (Fairchild Semiconductor, Bulk packaging) - Mid-range LED trigger current (15mA). Isolation voltage 4170Vrms. Package pitch 0.400" (10.16mm). IEC/EN/DIN and UL approvals. Bulk packaging format differs from tube. RoHS status not specified in documentation.

All substitute parts maintain active production status and share the MOC302 base product architecture. Selection depends on specific application requirements for isolation voltage, input drive current, package pitch compatibility, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can MOC3022M (Lite-On) be directly replaced with MOC3022M (onsemi)?

A: Yes. Both parts share identical part numbers and specifications: 5000Vrms isolation voltage, 10mA LED trigger current, and 0.300" (7.62mm) DIP pitch. Both are RoHS3 compliant and active in production. Substitution is direct.

Q: What is the primary difference between MOC3022M and MOC3023TVM?

A: The MOC3023TVM has a lower LED trigger current (5mA vs. 10mA), reducing input drive requirements. The MOC3023TVM uses 0.400" (10.16mm) DIP pitch instead of 0.300" (7.62mm), requiring PCB layout verification. Isolation voltage is 4170Vrms versus 5000Vrms.

Q: Are all substitute parts compatible with the same PCB footprint?

A: No. Parts with 0.300" (7.62mm) pitch (MOC3022M variants) are not footprint-compatible with 0.400" (10.16mm) pitch parts (MOC3020TVM, MOC3021TVM, MOC3022TVM, MOC3023TVM). PCB layout must be verified before substitution.

Q: What is the significance of the isolation voltage difference (5000Vrms vs. 4170Vrms)?

A: The MOC3022M (Lite-On) provides higher isolation voltage margin. Substitute parts with 4170Vrms isolation are suitable for applications within that voltage specification. Application requirements determine whether the lower isolation voltage is acceptable.

Q: Do all substitute parts have the same operating temperature range?

A: No. MOC3022M (Lite-On) operates from -40°C to 100°C. All onsemi and Fairchild substitutes operate from -40°C to 85°C. Applications requiring operation above 85°C must use the original Lite-On part.

Q: What packaging formats are available?

A: MOC3022M (onsemi) and MOC3022TVM are supplied in Tube packaging. MOC3023TVM and MOC3020TVM are supplied in Tube packaging. MOC3021TVM (Fairchild) is supplied in Bulk packaging. Packaging format affects handling and storage procedures.

Q: Are all substitute parts RoHS3 compliant?

A: MOC3022M (Lite-On), MOC3020TVM, MOC3022M (onsemi), MOC3022TVM, and MOC3023TVM are RoHS3 compliant. MOC3021TVM (Fairchild) RoHS status is not specified in the provided documentation.
