MOC3063FVM Equivalent & Substitute Parts

Part Overview

The MOC3063FVM is an optoisolator with triac output manufactured by onsemi, designed for high-voltage isolation applications. This component features a 7500Vpk isolation voltage rating, single channel configuration, and zero-crossing detection circuit in a 6-SMD surface mount package. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOC3063FVM is determined by the following critical parameters:

• Output Type: Must be Triac output
• Number of Channels: Must be single channel (1)
• Zero Crossing Circuit: Must include zero-crossing detection
• Mounting Type: Must be Surface Mount
• Package / Case: Must be 6-SMD, Gull Wing configuration
• Voltage - Off State: Must maintain 600 V rating
• Current Specifications: LED trigger current (Ift) and hold current (Ih) must be compatible

The MOC3063SVM qualifies as a substitute based on matching all core functional and mechanical parameters. While the isolation voltage differs (4170Vrms versus 7500Vpk), this represents a lower isolation rating that may be acceptable depending on application requirements.

Engineering Selection Recommendations

The MOC3063SVM is the designated substitute for the obsolete MOC3063FVM based on functional equivalence across all core parameters. The MOC3063SVM maintains active product status with onsemi, ensuring ongoing availability and support.

Key considerations for selection:

• Isolation Voltage: The MOC3063SVM provides 4170Vrms isolation versus the MOC3063FVM's 7500Vpk. Applications requiring the higher isolation rating of the original part cannot use this substitute without circuit redesign.
• Compliance: The MOC3063SVM carries ROHS3 compliance and IEC/EN/DIN and UL approvals, providing enhanced regulatory support compared to the obsolete original.
• Thermal Range: The MOC3063SVM specifies operating temperature range of -40°C to 85°C, whereas the original part does not provide this specification.
• Packaging: Both parts use identical 6-SMD, Gull Wing surface mount packaging, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can MOC3063SVM directly replace MOC3063FVM in all applications?

A: Direct replacement is possible only if the application does not require the 7500Vpk isolation voltage of the original part. The MOC3063SVM's 4170Vrms isolation rating is lower and must be evaluated against circuit isolation requirements.

Q: Are the packages identical between these parts?

A: Yes. Both MOC3063FVM and MOC3063SVM use 6-SMD, Gull Wing surface mount packaging, allowing direct PCB footprint compatibility without layout modifications.

Q: What is the significance of the zero-crossing circuit in both parts?

A: The zero-crossing detection circuit in both parts enables synchronization of triac switching with AC line voltage zero crossings, reducing electromagnetic interference and improving switching reliability in AC control applications.

Q: Does the MOC3063SVM meet current regulatory requirements?

A: Yes. The MOC3063SVM is ROHS3 compliant and carries IEC/EN/DIN and UL approvals, meeting current regulatory standards for electronic components.

Q: What are the LED trigger current requirements for both parts?

A: Both the MOC3063FVM and MOC3063SVM require a maximum LED trigger current (Ift) of 5mA and maintain a typical hold current (Ih) of 500µA, ensuring identical input drive requirements.
