MOC3052VM_F132 Equivalent & Substitute Parts

Part Overview

The MOC3052VM_F132 is an optoisolator with triac output manufactured by onsemi, designed for high-voltage isolation applications requiring 4170Vrms isolation rating. This component features a single-channel triac output in a 6-DIP package and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity and procurement planning. Active alternatives with identical or superior electrical characteristics are available from both onsemi and alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC3052VM_F132 is determined by the following critical parameters:

• Voltage - Isolation Rating: Minimum 4170Vrms required for direct substitution
• Output Type: Triac output configuration
• Number of Channels: Single channel
• Mounting Type: Through Hole
• Package Type: 6-DIP form factor
• Current - LED Trigger (Ift): Maximum 10mA
• Voltage - Off State: 600 V minimum
• Static dV/dt: Minimum 1kV/µs

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalents (onsemi MOC305 Series): Parts with identical isolation voltage (4170Vrms), matching electrical specifications, and active product status. These provide seamless replacement with no design modifications required.

Category 2 - Enhanced Alternatives (Vishay VO305 Series): Parts with superior isolation voltage (5300Vrms) and enhanced dV/dt rating (1.5kV/µs), offering improved performance margins while maintaining mechanical and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MOC3052M or MOC3052VM

Both MOC3052M and MOC3052VM are active onsemi products with identical electrical specifications to the obsolete MOC3052VM_F132. These parts provide direct functional replacement with no circuit modifications required. MOC3052VM maintains VDE approval matching the original part. Both are ROHS3 compliant and available in production quantities.

Secondary Recommendation: VO3052-X016

The Vishay VO3052-X016 offers enhanced performance with 5300Vrms isolation voltage and 1.5kV/µs dV/dt rating, providing superior noise immunity and transient protection. This part is suitable for applications requiring higher isolation margins or operating in more demanding electromagnetic environments. The 6-DIP package footprint differs slightly (0.400" vs 0.300"), requiring PCB layout verification. Extended operating temperature range (-55°C to 100°C) supports broader thermal applications. Approval agencies include cUR, UR, and VDE.

Compliance Considerations

All substitute parts maintain REACH Unaffected status and EAR99 classification. Selection should prioritize parts with active product status to ensure long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can MOC3052M directly replace MOC3052VM_F132 without circuit modifications?

A: Yes. MOC3052M shares identical electrical specifications including isolation voltage (4170Vrms), output type (triac), current ratings, and operating temperature range. Through-hole mounting and 6-DIP package dimensions are equivalent. No design changes are required.

Q: What is the difference between MOC3052M and MOC3052VM?

A: Both parts are electrically identical with matching isolation voltage, current ratings, and operating characteristics. MOC3052VM maintains VDE approval certification, while MOC3052M carries UR approval. Selection depends on certification requirements for your application.

Q: Is VO3052-X016 a direct substitute for MOC3052VM_F132?

A: VO3052-X016 is functionally compatible but not a direct substitute. While it maintains triac output, single-channel configuration, and 6-DIP through-hole mounting, the package dimensions differ (0.400" vs 0.300"). The isolation voltage is higher (5300Vrms vs 4170Vrms) and dV/dt rating is superior (1.5kV/µs vs 1kV/µs). PCB layout verification is required before implementation.

Q: Which substitute part should I select for new designs?

A: For new designs requiring 4170Vrms isolation, MOC3052M or MOC3052VM are recommended as active onsemi products with proven reliability. For applications requiring enhanced isolation margins or extended temperature operation, VO3052-X016 provides superior performance specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MOC3052M, MOC3052VM, and VO3052-X016 are all ROHS3 compliant. The original MOC3052VM_F132 compliance status was not specified in available documentation.

Q: What certifications do these parts carry?

A: MOC3052M carries UR approval. MOC3052VM carries UR and VDE approval. VO3052-X016 carries cUR, UR, and VDE approval. All parts maintain REACH Unaffected status and EAR99 classification.
