Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC3010VM are qualified based on the following criteria:

Mechanical Compatibility: All substitutes maintain identical 6-DIP (0.300", 7.62mm) through-hole packaging, ensuring direct pin-for-pin compatibility without PCB redesign.

Functional Equivalence: All substitutes provide single-channel triac output optoisolation with 250V off-state voltage rating and 100µA typical hold current, matching the core functional requirements of the MOC3010VM.

Electrical Parameters: Substitutes are grouped by isolation voltage rating and LED trigger current specifications. The MOC3010VM operates at 4170Vrms isolation; higher-rated substitutes (5300Vrms and 7.5Vpk) provide enhanced isolation margin and are electrically compatible for applications within the MOC3010VM's voltage envelope.

LED Trigger Current (Ift): The MOC3010VM specifies 15mA maximum trigger current. Substitute parts range from 5mA to 30mA maximum, with lower values (5mA, 10mA) offering improved LED efficiency and higher values (15mA, 25mA, 30mA) providing robust triggering margins.

Forward Voltage (Vf): The MOC3010VM specifies 1.15V typical forward voltage. Substitutes rated at 1.2V typical are within acceptable tolerance for LED drive circuit design.

Operating Temperature: The MOC3010VM operates -40°C to 85°C. Substitutes rated to -40°C to 100°C provide extended thermal operating range without functional degradation.

Regulatory Compliance: All substitutes maintain ROHS3 compliance, UL/VDE certifications, and REACH unaffected status, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Matched Isolation Voltage): MOC3010X and MOC3012X from Isocom provide 5300Vrms isolation rating with identical 6-DIP packaging and active product status. MOC3010X matches the 15mA LED trigger current specification of the MOC3010VM. MOC3012X offers the lowest trigger current at 5mA, reducing LED drive power requirements while maintaining full functional compatibility. Both parts carry UL/VDE certifications and ROHS3 compliance.

Enhanced Isolation Alternatives: H11J series parts (H11J1X, H11J2X, H11J3X, H11J4X, H11J5X) provide 5300Vrms isolation with extended operating temperature range (-40°C to 100°C) and documented static dV/dt rating of 10V/µs typical. These parts are suitable for applications requiring higher isolation margin or thermal headroom. H11J2X and H11J4X match the 15mA trigger current specification. H11J1X and H11J3X operate at 10mA trigger current for reduced LED power. H11J5X specifies 25mA trigger current for applications requiring robust gate drive.

High Isolation Option: MOC3009X provides 7.5Vpk isolation rating with 30mA maximum trigger current and extended temperature range. This part is suitable for applications where maximum isolation voltage margin is required, though the isolation specification differs in units from the MOC3010VM baseline.

LED Drive Optimization: For applications sensitive to LED power consumption, MOC3012X (5mA) and H11J1X/H11J3X (10mA) reduce input current requirements compared to the MOC3010VM (15mA). For applications requiring robust triggering margins, H11J5X (25mA) and MOC3009X (30mA) provide enhanced gate drive capability.

Thermal Performance: All substitute parts extend operating temperature to 100°C, compared to the MOC3010VM's 85°C maximum. This provides improved thermal margin for high-ambient or high-power applications.

Regulatory Compliance: All substitute parts maintain active product status, ROHS3 compliance, and UL/VDE certifications, ensuring regulatory equivalence for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can MOC3010X directly replace MOC3010VM in existing designs?

A: Yes. MOC3010X provides identical 6-DIP through-hole packaging, matching 15mA LED trigger current, 100µA hold current, and 250V off-state voltage. The higher 5300Vrms isolation rating (versus 4170Vrms) provides additional safety margin without functional impact. Both parts are active, ROHS3 compliant, and carry UL/VDE certifications.

Q: What is the difference between MOC3012X and MOC3010X?

A: Both parts provide 5300Vrms isolation in 6-DIP packaging with identical mechanical and thermal specifications. The primary difference is LED trigger current: MOC3012X specifies 5mA maximum, while MOC3010X specifies 15mA maximum. MOC3012X is preferred for LED power-constrained applications; MOC3010X matches the MOC3010VM trigger current specification.

Q: Are H11J series parts compatible with MOC3010VM?

A: Yes. H11J series parts (H11J1X through H11J5X) provide identical 6-DIP packaging, 250V off-state voltage, and 100µA hold current. All H11J variants offer 5300Vrms isolation and extended operating temperature (-40°C to 100°C). Compatibility depends on LED trigger current requirements: H11J1X/H11J3X (10mA), H11J2X/H11J4X (15mA), and H11J5X (25mA). Select based on application LED drive circuit design.

Q: What does the static dV/dt rating mean?

A: Static dV/dt (10V/µs typical for substitute parts) indicates the maximum rate of voltage change the triac output can withstand without false triggering. The MOC3010VM does not specify this parameter. Substitute parts with documented 10V/µs rating provide defined noise immunity for applications with fast voltage transients.

Q: Can I use MOC3009X as a substitute?

A: MOC3009X is functionally compatible in 6-DIP packaging with identical hold current and off-state voltage. However, the isolation specification (7.5Vpk) differs in units and magnitude from the MOC3010VM (4170Vrms). MOC3009X is suitable only if application isolation requirements are met by this specification. Verify isolation voltage compatibility before selection.

Q: Does higher isolation voltage affect circuit performance?

A: No. Higher isolation voltage ratings (5300Vrms versus 4170Vrms) provide additional safety margin without affecting triac output switching characteristics, hold current, or off-state voltage. Applications designed for 4170Vrms isolation operate identically with 5300Vrms-rated substitutes.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts use 6-DIP (0.300", 7.62mm) through-hole packaging, identical to the MOC3010VM. No PCB redesign or mechanical modification is required for substitution.

Q: What is the difference between onsemi and Isocom manufacturing?

A: Both manufacturers produce optoisolator triac output devices meeting identical functional and regulatory specifications. Isocom substitutes (MOC3010X, MOC3012X, H11J series) are active products with ROHS3 compliance and UL/VDE certifications equivalent to onsemi MOC3010VM. Selection between manufacturers depends on supply availability and procurement preferences.

Q: Which substitute offers the best LED efficiency?

A: MOC3012X specifies the lowest LED trigger current at 5mA maximum, reducing LED power consumption and drive circuit complexity. H11J1X and H11J3X specify 10mA maximum, providing moderate efficiency improvement over the MOC3010VM (15mA). Selection depends on LED drive circuit design constraints and application power budget.
