MOC3010FM Optoisolator Triac Output Equivalent & Substitute Parts

Part Overview

The MOC3010FM is a 7.5kV isolation optoisolator with triac output manufactured by onsemi in 6-SMD surface mount packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MOC3010FM serves applications requiring galvanic isolation in triac-driven circuits with high voltage isolation requirements. Substitute parts must maintain functional equivalence across isolation voltage, output type, channel configuration, and electrical trigger characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MOC3010FM is based on the following critical parameters:

Primary Substitution Criteria:

• Output Type: Triac (all substitutes must be triac output)
• Number of Channels: 1 (single channel isolation)
• Voltage - Isolation: Minimum 7500Vpk or equivalent RMS rating
• Voltage - Off State: 250V (standard across all candidates)
• Current - LED Trigger (Ift) Max: 15mA or lower (ensures compatibility with existing drive circuits)
• Current - Hold (Ih): 100µA typical (standard hold current)
• Current - DC Forward (If) Max: 60mA or lower

Substitution Groups:

Group 1: Surface Mount Direct Replacement (6-SMD)

• MOC3010SM (Fairchild Semiconductor): Same package, active product status, meets isolation and trigger specifications

Group 2: Through Hole Alternatives (6-DIP)

• EL3010, EL3011, EL3012 (Everlight Electronics): Active products with 5000Vrms isolation, 6-DIP package, varying trigger currents (5–15mA)
• H11J1, H11J2, H11J3, H11J4, H11J5 (Isocom Components): Active products with 5300Vrms isolation, 6-DIP package, varying trigger currents (10–25mA)
• MOC3009 (onsemi): Obsolete product with 5300Vrms isolation, 6-DIP package, 30mA trigger current

Substitution Constraints:

• Surface mount designs require MOC3010SM for package compatibility
• Through hole designs may use EL301x or H11Jx series with circuit board layout modifications
• Isolation voltage ratings below 7500Vpk represent reduced isolation margin; selection depends on application requirements
• Trigger current variations (5–30mA) require verification against drive circuit capabilities

Parameter Comparison

Engineering Selection Recommendations

For Surface Mount Applications (6-SMD): MOC3010SM is the primary substitute for MOC3010FM. Both share identical package geometry (6-SMD, Gull Wing) and electrical trigger specifications (15mA maximum). MOC3010SM maintains active product status with UL approval, ensuring long-term availability and compliance support. The isolation voltage rating of 4170Vrms is lower than the original 7500Vpk; applications requiring the full 7500Vpk isolation margin should conduct isolation voltage margin analysis before substitution.

For Through Hole Applications (6-DIP): When package conversion from surface mount to through hole is acceptable, multiple active alternatives exist:

• EL3012 (Everlight): Lowest trigger current requirement (5mA maximum), suitable for low-power drive circuits. ROHS3 compliant with CSA, DEMKO, FIMKO, NEMKO, SEMKO, and UL certifications.
• H11J4 (Isocom): Matches original 15mA trigger specification with 5300Vrms isolation. UL and VDE approved, ROHS3 compliant.
• EL3010 or EL3011 (Everlight): Alternative options with 5000Vrms isolation and varying trigger currents (10–15mA). Full international certification suite.

Compliance Considerations: All recommended active substitutes carry ROHS3 compliance and multiple international approvals (UL, VDE, CSA). The original MOC3010FM and MOC3009 are obsolete; active alternatives ensure regulatory support and manufacturing continuity.

Isolation Voltage Trade-offs: The MOC3010FM specifies 7500Vpk isolation. Substitute parts range from 4170Vrms (MOC3010SM) to 5300Vrms (H11J series, MOC3009). Applications with isolation voltage margins exceeding 30% above the working voltage can accommodate these lower ratings. Critical isolation applications should verify margin calculations against actual system requirements.

Frequently Asked Questions (FAQ)

Q: Can MOC3010SM directly replace MOC3010FM in surface mount designs? A: MOC3010SM shares the 6-SMD Gull Wing package and 15mA trigger specification with MOC3010FM. Electrical compatibility is confirmed for trigger and hold current parameters. The isolation voltage is lower (4170Vrms vs. 7500Vpk); verify that your application isolation margin accommodates this difference before substitution.

Q: What is the difference between the EL301x series variants (EL3010, EL3011, EL3012)? A: All three are 6-DIP through hole packages with 5000Vrms isolation and identical hold current (250µA typical). They differ in maximum LED trigger current: EL3010 requires 15mA, EL3011 requires 10mA, and EL3012 requires only 5mA. Select based on your drive circuit's current capability.

Q: How do H11J series parts differ from each other? A: The H11J1 through H11J5 series all share 5300Vrms isolation, 6-DIP package, and 100µA hold current. They vary in maximum trigger current: H11J1 and H11J3 require 10mA, H11J2 and H11J4 require 15mA, and H11J5 requires 25mA. Select the variant matching your drive circuit specifications.

Q: Is MOC3009 a suitable substitute for MOC3010FM? A: MOC3009 is obsolete, making it unsuitable for new designs requiring long-term availability. While it offers 5300Vrms isolation and 6-DIP package compatibility, its 30mA trigger requirement exceeds the original 15mA specification. Active alternatives (H11J series, EL301x) are preferred.

Q: Can I use a through hole part (6-DIP) in a surface mount design? A: No. Through hole 6-DIP packages require different PCB footprints and assembly processes than surface mount 6-SMD packages. Design conversion is necessary. For surface mount designs, MOC3010SM is the appropriate substitute.

Q: What certifications should I verify for my application? A: All active substitute parts carry UL approval and ROHS3 compliance. The EL301x series includes additional certifications (CSA, DEMKO, FIMKO, NEMKO, SEMKO). The H11J series includes VDE approval. Verify that your application requirements align with the certifications provided by your selected substitute.

Q: Does isolation voltage rating affect circuit performance? A: Isolation voltage rating determines the maximum voltage differential the component can withstand between input and output sides. Lower ratings reduce isolation margin. Applications operating near the component's rated voltage should maintain margin calculations. The MOC3010FM's 7500Vpk rating provides higher margin than 5000–5300Vrms alternatives; verify your system's actual isolation requirements before substitution.

Q: Are all substitutes RoHS compliant? A: All active substitutes (MOC3010SM, EL301x series, H11J series) are ROHS3 compliant. The original MOC3010FM and obsolete MOC3009 do not specify RoHS status. For new designs, active compliant alternatives are required.
