MOC3052FR2VM Equivalent & Substitute Parts

Part Overview

The MOC3052FR2VM is a 7.5kV isolation optoisolator with triac output manufactured by onsemi in a 6-SMD surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The device provides galvanic isolation suitable for AC power control applications requiring high voltage isolation and triac switching capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC3052FR2VM are identified based on the following critical parameters that determine functional compatibility:

• Output Type: Triac
• Number of Channels: 1
• Voltage - Isolation: Minimum 5300Vrms (equivalent to 7500Vpk peak)
• Voltage - Off State: 600 V
• Current - LED Trigger (Ift) (Max): 10mA
• Current - DC Forward (If) (Max): 60 mA
• Base Product Number: MOC305 or equivalent series
• Regulatory Compliance: UR, VDE, or cUR certifications

The MOC3052SR2VM maintains identical electrical specifications and surface mount packaging, providing direct substitution. The VO3052-X016 offers equivalent isolation voltage (5300Vrms) and triac output functionality but differs in mounting technology (through-hole 6-DIP versus surface mount 6-SMD) and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

MOC3052SR2VM is the primary substitute for direct replacement in surface mount applications. This part maintains active product status with onsemi/Fairchild lineage, ensuring long-term availability and supply chain stability. Both UR and VDE certifications align with the original component's regulatory requirements.

VO3052-X016 serves as an alternative for applications where through-hole mounting is acceptable or preferred. This Vishay component provides extended operating temperature range (-55°C to 100°C) and ROHS3 compliance, offering enhanced environmental performance. The slightly lower hold current (200µA typical versus 280µA) and marginally higher forward voltage (1.2V versus 1.15V) remain within acceptable operational margins for triac output optoisolators. The 5300Vrms isolation rating meets or exceeds typical application requirements.

Selection between these substitutes depends on PCB assembly technology (surface mount versus through-hole) and environmental operating conditions. Both parts carry appropriate regulatory certifications for industrial and safety-critical applications.

Frequently Asked Questions (FAQ)

Q: Can MOC3052SR2VM directly replace MOC3052FR2VM on existing PCBs?

A: Yes, MOC3052SR2VM is a direct substitute. Both components use identical 6-SMD surface mount packaging and share the same pin configuration. No PCB layout modifications are required.

Q: What are the key differences between MOC3052SR2VM and VO3052-X016?

A: The primary differences are mounting technology and package type. MOC3052SR2VM uses surface mount 6-SMD packaging, while VO3052-X016 uses through-hole 6-DIP packaging. VO3052-X016 offers a wider operating temperature range (-55°C to 100°C versus -40°C to 85°C) and includes ROHS3 compliance. Isolation voltage specifications differ: MOC3052SR2VM data is not fully specified, while VO3052-X016 provides 5300Vrms isolation.

Q: Is VO3052-X016 suitable for applications originally designed for MOC3052FR2VM?

A: VO3052-X016 is functionally compatible for triac output optoisolator applications requiring 1-channel isolation with 600V off-state voltage. However, PCB redesign is necessary due to different mounting technology (through-hole versus surface mount). The 5300Vrms isolation rating is adequate for most industrial AC control applications.

Q: What regulatory certifications apply to these substitute parts?

A: MOC3052FR2VM carries UR and VDE approvals. MOC3052SR2VM maintains these certifications through the onsemi/Fairchild product line. VO3052-X016 includes cUR, UR, and VDE certifications, providing broader regulatory coverage including Canadian applications.

Q: Are there inventory considerations when selecting a substitute?

A: MOC3052SR2VM has significantly higher inventory availability (63,400 pcs) compared to MOC3052FR2VM (656 pcs). VO3052-X016 maintains moderate inventory (2,813 pcs). For long-term production requirements, MOC3052SR2VM offers superior supply chain security.
