MOC3011 Equivalent & Substitute Parts

Part Overview

The MOC3011 is an optoisolator with triac output, rated for 5300Vrms isolation voltage, designed for single-channel applications in 6-DIP through-hole packaging. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The MOC3011 provides galvanic isolation between input and output circuits while delivering triac-based switching capability for AC load control.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC3011 is determined by the following critical parameters:

• Output Type: Must be triac output for AC switching functionality
• Number of Channels: Single channel requirement
• Package / Case: 6-DIP through-hole form factor for PCB compatibility
• Mounting Type: Through hole for existing board layouts
• Isolation Voltage: Minimum 4170Vrms acceptable for applications not requiring the full 5300Vrms rating
• Current Ratings: LED trigger current (Ift) and hold current (Ih) must remain within specified ranges
• Regulatory Compliance: REACH and ECCN classifications must align with application requirements

The MOC3011M qualifies as a direct substitute based on matching output type, channel count, package configuration, and mounting method. While the isolation voltage is reduced from 5300Vrms to 4170Vrms, this remains within acceptable parameters for standard triac driver applications.

Parameter Comparison

Engineering Selection Recommendations

The MOC3011M is the designated substitute for the obsolete MOC3011. Both components are manufactured by onsemi and maintain identical package, mounting, and channel configurations. The MOC3011M carries active product status, ensuring continued availability and supply chain reliability.

The primary difference is the reduction in isolation voltage from 5300Vrms to 4170Vrms. This reduction is acceptable for applications where the lower isolation rating meets system requirements. The MOC3011M provides improved current handling capability (60mA maximum forward current versus 50mA), offering enhanced performance margins in triac driver circuits.

Both components maintain REACH compliance and identical ECCN classification, supporting regulatory requirements across standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can MOC3011M directly replace MOC3011 in existing designs?

A: Yes, provided the application does not require the full 5300Vrms isolation voltage. The MOC3011M delivers 4170Vrms isolation, which is suitable for standard triac driver applications. Verify your system isolation requirements before substitution.

Q: Are the package dimensions identical between MOC3011 and MOC3011M?

A: Yes. Both components use 6-DIP (0.300", 7.62mm) through-hole packaging, ensuring direct PCB compatibility without layout modifications.

Q: What is the difference in current ratings between these parts?

A: The MOC3011M supports 60mA maximum forward current compared to 50mA for the MOC3011. LED trigger current (Ift) and hold current (Ih) specifications remain identical at 10mA and 100µA respectively.

Q: Is the MOC3011M RoHS compliant?

A: Yes. The MOC3011M is ROHS3 compliant, meeting current environmental standards. The original MOC3011 does not specify RoHS status.

Q: Why is the MOC3011 classified as obsolete?

A: The MOC3011 has been discontinued by onsemi. The MOC3011M represents the active product line continuation with equivalent functionality and improved availability.
