Substitute Part Grouping Explanation

Substitution for the MOC3011TM is determined by the following critical parameters:

Package compatibility: 6-DIP (0.400", 10.16mm) through-hole form factor
Output type: Triac output configuration
Number of channels: Single channel
Isolation voltage: Minimum 4170Vrms (equal or higher)
Off-state voltage: 250 V
LED trigger current (Ift): Maximum 10mA or lower
Hold current (Ih): 100µA or higher
Forward voltage (Vf): Approximately 1.15V to 1.2V
DC forward current (If): 50mA to 60mA maximum
Operating temperature range: Must encompass or exceed -40°C to 85°C
Mounting type: Through hole

Substitute parts are grouped into two categories based on isolation voltage capability and LED trigger current specifications:

Category A - Higher Isolation Voltage (5000Vrms to 5300Vrms): Everlight Electronics EL3010M, EL3011M, EL3012M and Isocom H11J1G, H11J2G, H11J3G, H11J4G, H11J5G, MOC3009G, MOC3010G. These parts exceed the MOC3011TM isolation voltage rating and provide enhanced isolation margin.

Category B - Matched Isolation Voltage: Parts within this category maintain electrical compatibility through equivalent isolation voltage and triac output characteristics.

Engineering Selection Recommendations

Primary Substitutes - Everlight Electronics Series (EL3010M, EL3011M, EL3012M)

The Everlight EL3011M provides the closest electrical match to the MOC3011TM with identical 10mA LED trigger current specification and 5000Vrms isolation voltage. This part is active in production with ROHS3 compliance and multiple international certifications (CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL). The EL3011M supports the extended operating temperature range of -55°C to 100°C, exceeding the MOC3011TM specification.

The EL3012M offers the lowest LED trigger current at 5mA maximum, providing reduced driver circuit complexity. The EL3010M accommodates higher trigger current requirements at 15mA maximum.

Secondary Substitutes - Isocom H11J Series (H11J1G through H11J5G)

The Isocom H11J3G matches the MOC3011TM LED trigger current specification at 10mA maximum with 5300Vrms isolation voltage. All H11J variants are active products with ROHS3 compliance and UL/VDE certifications. The H11J series provides 100µA hold current matching the MOC3011TM specification.

Selection within the H11J series depends on LED trigger current requirements: H11J1G and H11J3G at 10mA, H11J2G and H11J4G at 15mA, and H11J5G at 25mA maximum.

Alternative Substitutes - Isocom MOC3009G and MOC3010G

The MOC3009G and MOC3010G are active Isocom products with 5300Vrms isolation voltage and UL/VDE certifications. MOC3009G specifies 30mA LED trigger current. MOC3010G isolation voltage is specified as 7.5Vpk, which differs from the standard Vrms rating convention used in other parts.

All substitute parts maintain 6-DIP through-hole package compatibility and triac output configuration with single-channel operation.

Frequently Asked Questions (FAQ)

Q: Can EL3011M directly replace MOC3011TM in existing designs?

A: Yes. The EL3011M maintains identical 10mA LED trigger current, 100µA hold current, and 250V off-state voltage specifications. The 6-DIP package pinout is compatible. The higher 5000Vrms isolation voltage provides additional safety margin. Verify circuit board layout accommodates standard 6-DIP spacing of 0.400 inches (10.16mm).

Q: What is the difference between Everlight EL3010M, EL3011M, and EL3012M?

A: These parts differ only in LED trigger current specification. EL3010M requires 15mA maximum, EL3011M requires 10mA maximum, and EL3012M requires 5mA maximum. All three share identical 5000Vrms isolation voltage, 250V off-state voltage, and 6-DIP package. Select based on driver circuit current capability.

Q: How do Isocom H11J variants differ from each other?

A: The H11J series variants are differentiated by LED trigger current: H11J1G and H11J3G at 10mA, H11J2G and H11J4G at 15mA, and H11J5G at 25mA maximum. All maintain 5300Vrms isolation voltage, 100µA hold current, and 6-DIP package compatibility. Choose the variant matching your driver circuit specifications.
