Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC3022FR2VM is determined by the following critical parameters:

Primary Substitution Criteria:

• Output Type: Triac (all substitutes must be triac output optoisolators)
• Number of Channels: 1 (single channel isolation)
• Voltage - Off State: 400 V (maximum off-state voltage rating)
• Current - LED Trigger (Ift): 10mA maximum (input trigger current)
• Current - Hold (Ih): 100µA typical (holding current)
• Current - DC Forward (If): 60 mA maximum (LED forward current)

Substitution Grouping:

Group 1 - Surface Mount Direct Equivalent:

• MOC3022SR2VM (Fairchild Semiconductor): Active product status, surface mount package, matching electrical characteristics within acceptable tolerance

Group 2 - Through Hole Alternatives (Package Change Required):

• MOC3020X, MOC3021X, MOC3022X, MOC3023X (Isocom Components 2004 LTD): Active product status, 6-DIP through hole package, isolation voltage 5300Vrms, matching triac output and channel configuration
• VO3023-X001 (Vishay Semiconductor Opto Division): Active product status, 6-DIP through hole package, isolation voltage 5000Vrms, matching triac output and channel configuration

All substitute parts maintain the same base product number (MOC302 series) and triac output topology, ensuring functional compatibility within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

MOC3022SR2VM (Fairchild Semiconductor) is the primary direct substitute for surface mount applications. It maintains the same 6-SMD gull wing package and electrical interface, requiring no PCB layout modifications. Product status is active with IEC/EN/DIN and UL approvals. The isolation voltage rating of 4170Vrms is lower than the original 7500Vpk specification; verify application requirements before selection.

MOC3020X, MOC3021X, MOC3022X, MOC3023X (Isocom Components 2004 LTD) are suitable for through-hole implementations. All are active products with ROHS3 compliance and UR/VDE approvals. These parts feature 5300Vrms isolation voltage and 6-DIP package configuration. Selection among these variants depends on LED trigger current requirements: MOC3020X (30mA), MOC3021X (15mA), MOC3022X (10mA), or MOC3023X (5mA). PCB redesign is required to accommodate the through-hole package.

VO3023-X001 (Vishay Semiconductor Opto Division) offers the broadest approval agency coverage (CQC, CSA, cUL, FIMKO, UL, VDE) and highest static dV/dt rating (100V/µs). Isolation voltage is 5000Vrms with 6-DIP through-hole package. This option is suitable for applications requiring enhanced regulatory compliance or high dV/dt performance.

Frequently Asked Questions (FAQ)

Q: Can MOC3022SR2VM directly replace MOC3022FR2VM without PCB changes?

A: Yes. Both parts use the 6-SMD gull wing surface mount package with identical pinout and electrical interface. No PCB layout modifications are required. However, verify that the lower isolation voltage rating (4170Vrms vs. 7500Vpk) meets your application requirements.

Q: What is the difference between MOC3020X, MOC3021X, MOC3022X, and MOC3023X?

A: These Isocom parts differ only in LED trigger current (Ift) specification: MOC3020X requires 30mA maximum, MOC3021X requires 15mA maximum, MOC3022X requires 10mA maximum, and MOC3023X requires 5mA maximum. All other electrical parameters and package configuration are identical. Select based on your input drive circuit capability.

Q: Do through-hole substitutes require PCB redesign?

A: Yes. The MOC3020X, MOC3021X, MOC3022X, MOC3023X, and VO3023-X001 use 6-DIP through-hole packages, while the original MOC3022FR2VM is surface mount (6-SMD). PCB footprint and layout modifications are necessary.

Q: Which substitute has the highest isolation voltage rating?

A: The MOC3022FR2VM original part specifies 7500Vpk isolation. Among active substitutes, MOC3020X, MOC3021X, MOC3022X, and MOC3023X provide 5300Vrms, while VO3023-X001 provides 5000Vrms. None match the original specification; verify application isolation requirements.

Q: What are the regulatory compliance differences?

A: MOC3022SR2VM carries IEC/EN/DIN and UL approvals. Isocom parts (MOC3020X, MOC3021X, MOC3022X, MOC3023X) carry UR and VDE approvals with ROHS3 compliance. VO3023-X001 has the broadest coverage: CQC, CSA, cUL, FIMKO, UL, and VDE approvals. Select based on your target market and regulatory requirements.

Q: Is VO3023-X001 compatible with applications requiring high dV/dt performance?

A: Yes. VO3023-X001 specifies 100V/µs static dV/dt, significantly higher than the 10V/µs typical rating of Isocom parts. This makes it suitable for applications with fast voltage transients. However, package change from surface mount to through-hole is required.
