Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC3061FVM is determined by the following critical parameters:

• Output Type: Triac output configuration
• Package / Case: 6-SMD, Gull Wing surface mount form factor
• Number of Channels: Single channel isolation
• Zero Crossing Circuit: Integrated zero crossing detection
• Voltage - Off State: 600 V rating
• Current - LED Trigger (Ift) (Max): 15mA maximum
• Current - Hold (Ih) (Typ): 500µA typical hold current
• Current - DC Forward (If) (Max): 60 mA maximum forward current
• Mounting Type: Surface Mount compatibility

The MOC3061SVM qualifies as a substitute based on matching these core electrical and mechanical parameters. While the isolation voltage rating differs (4170Vrms vs. 7500Vpk), the MOC3061SVM maintains compatibility with the same package footprint, channel configuration, and triac output characteristics.

Engineering Selection Recommendations

The MOC3061SVM is the active equivalent for the obsolete MOC3061FVM. Selection of the MOC3061SVM is supported by the following factors:

• Product Status: The MOC3061SVM maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance: The MOC3061SVM carries ROHS3 compliance and IEC/EN/DIN and UL approvals, meeting current regulatory requirements.
• Package Compatibility: Both parts share identical 6-SMD, Gull Wing surface mount packaging, enabling direct PCB footprint compatibility.
• Electrical Compatibility: Core electrical parameters including triac output, zero crossing circuit, trigger current, hold current, and forward current specifications are identical.
• Isolation Voltage Consideration: The MOC3061SVM provides 4170Vrms isolation versus the MOC3061FVM's 7500Vpk isolation. Design applications requiring the higher isolation rating of the MOC3061FVM must evaluate whether the reduced isolation of the MOC3061SVM meets system requirements.

Frequently Asked Questions (FAQ)

Q: Can the MOC3061SVM directly replace the MOC3061FVM on existing PCBs?

A: Yes, the MOC3061SVM shares the identical 6-SMD, Gull Wing package footprint with the MOC3061FVM, enabling direct PCB placement compatibility without layout modifications.

Q: What is the primary difference between these two parts?

A: The isolation voltage rating differs: MOC3061FVM provides 7500Vpk isolation, while MOC3061SVM provides 4170Vrms isolation. All other electrical parameters, including output type, channel configuration, trigger current, hold current, and forward current specifications, are identical.

Q: Is the MOC3061SVM suitable for applications originally designed for the MOC3061FVM?

A: Suitability depends on the isolation voltage requirement of the application. If the design specifies 7500Vpk isolation as a critical parameter, the MOC3061SVM's 4170Vrms isolation may not meet requirements. If isolation voltage is not a limiting factor, the MOC3061SVM is functionally equivalent.

Q: What certifications does the MOC3061SVM carry?

A: The MOC3061SVM carries IEC/EN/DIN and UL approvals and is ROHS3 compliant, meeting current regulatory and environmental standards.

Q: Are there inventory considerations between these parts?

A: The MOC3061FVM is obsolete with limited remaining inventory (1156 pcs). The MOC3061SVM is in active production with significantly higher inventory availability (23600 pcs), supporting long-term procurement requirements.

Q: What is the operating temperature range of the MOC3061SVM?

A: The MOC3061SVM operates across -40°C to 85°C, providing standard industrial temperature range coverage.
