Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC3011FVM is determined by the following critical parameters:

Primary Substitution Criteria:

• Output Type: Triac (mandatory match)
• Number of Channels: 1 (mandatory match)
• Voltage - Isolation: Minimum 7500Vpk or equivalent Vrms rating
• Voltage - Off State: 250 V (standard across all candidates)
• Current - LED Trigger (Ift): 10mA or lower (ensures compatibility with existing drive circuits)
• Current - Hold (Ih): 100µA or lower (typ)
• Current - DC Forward (If): 60 mA or lower

Substitution Groups:

Group A - Direct Functional Equivalents (Surface Mount): No surface mount alternatives are available in the provided substitute list. All alternatives are through-hole packages.

Group B - Through-Hole Alternatives with Reduced Isolation Voltage (5000-5300Vrms): These parts meet the triac output, single-channel, and current specifications but operate at lower isolation voltages (5000-5300Vrms vs. 7500Vpk). Substitution is valid only when circuit isolation requirements permit operation at these lower ratings.

• EL3010-V, EL3011-V, EL3012-V (Everlight Electronics)
• H11J1X, H11J2X, H11J3X, H11J4X, H11J5X (Isocom Components)
• MOC3010X (Isocom Components)

Group C - Through-Hole Alternative with Significantly Reduced Isolation Voltage (7.5Vpk): MOC3009X does not meet isolation voltage requirements and is not a valid substitute.

Parameter Comparison

Engineering Selection Recommendations

For Direct Form-Fit-Function Replacement: No direct replacement exists. The MOC3011FVM is a surface mount 6-SMD component with 7500Vpk isolation. All available substitutes are through-hole 6-DIP packages with lower isolation ratings (5000-5300Vrms).

For Circuit-Level Substitution (Isolation Voltage Reduction Acceptable):

Preferred Candidates (Active Product Status, Full Compliance):

EL3011-V and H11J1X or H11J3X are the closest functional matches when isolation voltage reduction from 7500Vpk to 5000-5300Vrms is acceptable:

• EL3011-V: Matches 10mA LED trigger current, active status, ROHS3 compliant, multiple agency approvals (CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL, VDE)
• H11J1X and H11J3X: Match 10mA LED trigger current, 100µA hold current (typ), active status, ROHS3 compliant, UL and VDE approvals

Alternative Candidates (Specific Current Requirements):

• EL3012-V: Lowest LED trigger current (5mA), suitable for low-drive applications
• H11J2X, H11J4X, MOC3010X: 15mA LED trigger current, suitable for standard drive circuits
• H11J5X: Highest LED trigger current (25mA), suitable for high-noise environments

Package Consideration: All substitutes require PCB redesign from surface mount to through-hole configuration. Current-DC forward ratings differ: Everlight parts maintain 60mA (matching original), while Isocom parts reduce to 50mA.

Frequently Asked Questions (FAQ)

Q: Can I use a 5000-5300Vrms rated part to replace the 7500Vpk MOC3011FVM?

A: Only if your circuit design permits operation at the lower isolation voltage. The 5000-5300Vrms rating is approximately 67-70% of the original 7500Vpk specification. Verify that your isolation requirements, safety margins, and regulatory compliance allow this reduction before substitution.

Q: What is the difference between Vpk and Vrms isolation ratings?

A: Vpk (peak voltage) and Vrms (RMS voltage) are different measurement standards for isolation voltage. Direct comparison requires understanding your specific circuit's voltage profile. Consult your system design documentation to determine which rating applies to your application.

Q: Why are all substitutes through-hole packages when the original is surface mount?

A: The MOC3011FVM is obsolete, and active production of 7500Vpk optoisolators with triac output is limited. Manufacturers have transitioned to lower isolation voltage ratings (5000-5300Vrms) in through-hole packages for this component class.

Q: Which substitute has the closest LED trigger current to the original 10mA specification?

A: EL3011-V, H11J1X, and H11J3X all specify 10mA maximum LED trigger current, matching the MOC3011FVM exactly. These are the best choices for drive circuit compatibility.

Q: Are all substitutes RoHS compliant?

A: Yes. EL3010-V, EL3011-V, and EL3012-V are ROHS3 compliant. H11J1X, H11J2X, H11J3X, H11J4X, H11J5X, and MOC3010X are ROHS3 compliant. All candidates meet current environmental standards.

Q: What certifications should I prioritize for safety-critical applications?

A: Everlight EL series parts carry the broadest agency approvals: CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL, and VDE. Isocom H11J series and MOC3010X carry UL and VDE approvals. Select based on your regional regulatory requirements.
