Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC3010FVM is determined by the following critical parameters:

Primary Substitution Criteria:

• Output Type: Triac (non-negotiable)
• Number of Channels: 1 (non-negotiable)
• Voltage - Off State: 250 V (required for AC switching applications)
• Current - LED Trigger (Ift) (Max): 15mA or lower (ensures compatibility with existing drive circuits)
• Current - Hold (Ih): 100µA or higher (maintains triac latching)
• Current - DC Forward (If) (Max): 50-60 mA (input LED current compatibility)

Secondary Considerations:

• Voltage - Isolation: Minimum 5000Vrms or 7500Vpk (higher isolation acceptable)
• Mounting Type: Surface mount preferred; through-hole acceptable with board redesign
• Package compatibility: 6-SMD direct replacement; 6-DIP requires PCB layout modification

The substitute parts listed below meet the primary criteria. Everlight Electronics EL3010-V, EL3011-V, and EL3012-V series provide 5000Vrms isolation in through-hole 6-DIP packages. Isocom H11J series and MOC3010X provide 5300Vrms isolation, also in 6-DIP configuration. MOC3009X offers equivalent isolation in through-hole format.

Parameter Comparison

Engineering Selection Recommendations

Direct Functional Equivalents (Recommended for Obsolescence Replacement):

MOC3010X (Isocom) is the closest functional equivalent, offering 5300Vrms isolation with matching 15mA trigger current and 100µA hold current. This part maintains active product status and carries UL and VDE certifications. The primary design change required is PCB layout modification from 6-SMD surface mount to 6-DIP through-hole configuration.

H11J2X and H11J4X (Isocom H11J series) provide equivalent trigger current specifications (15mA) with 5300Vrms isolation and 100µA hold current. Both carry UL and VDE approvals and maintain active status. These parts are suitable for applications where the reduced DC forward current (50mA vs. 60mA) is acceptable.

Lower Trigger Current Alternatives:

EL3011-V and H11J1X, H11J3X offer 10mA trigger current, reducing input LED drive requirements. EL3011-V provides 5000Vrms isolation with UL, VDE, CSA, DEMKO, FIMKO, NEMKO, and SEMKO certifications. H11J series variants maintain UL and VDE approvals.

Minimum Trigger Current Option:

EL3012-V requires only 5mA trigger current, suitable for low-power drive circuits. This part carries comprehensive agency approvals (UL, VDE, CSA, DEMKO, FIMKO, NEMKO, SEMKO) and maintains active product status with 5000Vrms isolation.

Higher Trigger Current Tolerance:

H11J5X accommodates 25mA trigger current with 5300Vrms isolation and active product status. This part is suitable for applications with higher input drive capability.

All recommended substitutes maintain 250V off-state voltage and triac output configuration. Product status verification confirms all substitutes are active, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can MOC3010X directly replace MOC3010FVM without circuit modification?

A: MOC3010X is functionally equivalent but requires PCB layout modification. The MOC3010FVM uses 6-SMD surface mount packaging, while MOC3010X uses 6-DIP through-hole configuration. Pin assignments are compatible, but board footprint redesign is necessary.

Q: What is the isolation voltage difference between 7500Vpk and 5000Vrms?

A: 7500Vpk (peak voltage) and 5000Vrms (RMS voltage) represent different measurement standards. 5000Vrms equals approximately 7071Vpk, making 5000Vrms-rated parts suitable for applications originally designed for 7500Vpk isolation. The 250V off-state voltage specification remains consistent across all parts.

Q: Which substitute part has the lowest input LED trigger current requirement?

A: EL3012-V requires the minimum trigger current at 5mA maximum, compared to MOC3010FVM's 15mA. This reduces input drive circuit complexity and power consumption. EL3012-V maintains 5000Vrms isolation and 250V off-state voltage.

Q: Are all substitute parts RoHS compliant?

A: Everlight Electronics EL3010-V, EL3011-V, and EL3012-V are ROHS3 compliant. Isocom H11J series (H11J1X through H11J5X), MOC3009X, and MOC3010X are ROHS3 compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What certifications apply to substitute parts?

A: Everlight Electronics parts carry CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL, and VDE approvals. Isocom H11J series and MOC3010X carry UL and VDE approvals. MOC3009X carries UL and VDE approvals. All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Can through-hole 6-DIP parts be used in surface mount applications?

A: Through-hole 6-DIP parts require PCB design modification including through-hole vias and mechanical mounting provisions. Surface mount assembly equipment cannot directly place through-hole components. Design conversion is necessary but technically feasible.

Q: Which substitute offers the best hold current specification?

A: Everlight Electronics EL3010-V, EL3011-V, and EL3012-V specify 250µA typical hold current, compared to MOC3010FVM's 100µA. Higher hold current ensures more robust triac latching. Isocom H11J series and MOC3010X maintain 100µA hold current matching the original specification.
