MOC3022SR2VM Equivalent & Substitute Parts

Part Overview

The MOC3022SR2VM is an optoisolator with triac output manufactured by onsemi, designed for high-voltage isolation applications. This component features a 4170Vrms isolation voltage rating, single-channel triac output, and surface-mount 6-SMD packaging in tape & reel format. The part is currently active in production with 1675 units in stock.

Equivalent and substitute parts are necessary when the original MOC3022SR2VM becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from the MOC302x series with compatible electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the MOC302x series are qualified based on the following criteria:

Electrical Compatibility Parameters:

• Output Type: Triac (all substitutes maintain triac output)
• Number of Channels: 1 (single-channel configuration)
• Voltage - Off State: 400 V (consistent across all parts)
• Voltage - Forward (Vf): 1.15V (identical forward voltage)
• Mounting Type: Surface Mount, 6-SMD, Gull Wing (identical package form factor)
• RoHS Status: ROHS3 Compliant (regulatory compliance maintained)
• Moisture Sensitivity Level: 1 (Unlimited) (identical MSL rating)

Substitution Allowances:

• Voltage - Isolation: Substitute parts rated at 5000Vrms exceed the 4170Vrms requirement and are acceptable for applications requiring the MOC3022SR2VM
• Current - LED Trigger (Ift): Substitute parts with Ift values of 5mA, 10mA, or 15mA are compatible with circuits designed for 10mA trigger current
• Current - Hold (Ih): Substitute parts rated at 250µA (Typ) exceed the 100µA requirement and are acceptable
• Current - DC Forward (If): Substitute parts rated at 50mA meet or exceed the 60mA maximum requirement
• Operating Temperature: Substitute parts rated to 100°C provide extended temperature range compared to the 85°C maximum of MOC3022SR2VM
• Packaging Format: Substitutes available in Tube, Cut Tape (CT) & Digi-Reel®, or Tape & Reel formats

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and comply with ROHS3 regulations. The MOC302x series from Lite-On Inc. carries expanded approval agency certifications including CQC, CSA, TUV, UL, and VDE, compared to the onsemi MOC3022SR2VM which carries IEC/EN/DIN and UL approvals.

For direct electrical equivalence with identical LED trigger current (10mA): MOC3022S or MOC3022S-TA1 are the closest functional matches, both rated at 5000Vrms isolation voltage with 10mA maximum trigger current.

For applications requiring lower trigger current: MOC3023S or MOC3023S-TA1 operate at 5mA trigger current, suitable for circuits with reduced LED drive capability.

For applications permitting higher trigger current: MOC3021S or MOC3021S-TA1 operate at 15mA trigger current, and MOC3020S operates at 30mA trigger current.

For packaging format requirements: Cut Tape (CT) & Digi-Reel® variants (-TA1 suffix) are available for MOC3021S, MOC3022S, and MOC3023S. Tube packaging is available for all Lite-On variants. The original MOC3022SR2VM is supplied in Tape & Reel format.

For extended temperature operation: All Lite-On substitutes support -40°C to 100°C operating range, exceeding the MOC3022SR2VM specification of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can MOC3022S replace MOC3022SR2VM directly?

A: MOC3022S is electrically compatible with identical 10mA LED trigger current and 6-SMD gull wing package. The primary differences are manufacturer (Lite-On vs. onsemi), higher isolation voltage rating (5000Vrms vs. 4170Vrms), extended temperature range (-40°C to 100°C vs. -40°C to 85°C), and packaging format (Tube vs. Tape & Reel). Electrical performance in the application circuit remains equivalent.

Q: What is the difference between MOC3022S and MOC3022S-TA1?

A: Both parts are identical electrically and mechanically. The difference is packaging format: MOC3022S is supplied in Tube packaging, while MOC3022S-TA1 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on manufacturing equipment compatibility and assembly process requirements.

Q: Why do substitute parts have higher isolation voltage ratings?

A: The MOC302x series substitutes are rated at 5000Vrms isolation voltage, which exceeds the MOC3022SR2VM specification of 4170Vrms. Higher isolation voltage ratings are backward compatible and provide additional safety margin in high-voltage isolation applications. No circuit modification is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts carry ROHS3 compliance certification identical to the MOC3022SR2VM. All parts also maintain Moisture Sensitivity Level 1 (Unlimited) rating.

Q: Which substitute has the highest inventory availability?

A: MOC3023S-TA1 has the highest inventory with 155,300 units in stock, followed by MOC3022S-TA1 with 125,300 units. Both are available in Cut Tape (CT) & Digi-Reel® packaging format.

Q: Can I use MOC3020S with 30mA trigger current in a circuit designed for 10mA?

A: MOC3020S requires 30mA maximum LED trigger current compared to the 10mA requirement of MOC3022SR2VM. This part is compatible only if the circuit design can supply the higher trigger current. Verify LED drive circuit capability before substitution.

Q: What approval agencies certify these substitute parts?

A: MOC3022SR2VM carries IEC/EN/DIN and UL approvals. All Lite-On substitute parts carry CQC, CSA, TUV, UL, and VDE approvals, providing expanded regulatory coverage for international applications.
