MOC3063M Equivalent & Substitute Parts

Part Overview

The MOC3063M is an optoisolator with triac output manufactured by Lite-On Inc., designed for applications requiring galvanic isolation up to 5000Vrms. This component features a single channel with zero-crossing detection, making it suitable for AC load switching applications. The part is currently in active production status with substantial inventory availability (105,200 pcs). Alternative components may be required due to supply constraints, design optimization needs, or specific application requirements for enhanced isolation voltage or operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

The VO3063-X006 (Vishay Semiconductor Opto Division) qualifies as a direct substitute for the MOC3063M based on the following critical parameters:

• Output Type: Both components feature triac output configuration
• Zero Crossing Circuit: Both include zero-crossing detection
• Number of Channels: Both provide single-channel isolation
• Package / Case: Both use 6-DIP (0.400", 10.16mm) form factor for through-hole mounting
• Current - LED Trigger (Ift) (Max): Both specify 5mA maximum trigger current
• Voltage - Forward (Vf) (Typ): Both specify 1.2V typical forward voltage
• Voltage - Off State: Both specify 600V off-state voltage
• RoHS Status: Both are ROHS3 compliant

The VO3063-X006 provides enhanced specifications in isolation voltage (5300Vrms vs. 5000Vrms), static dV/dt rating (1.5kV/µs vs. 1kV/µs), and extended lower operating temperature limit (-55°C vs. -40°C), while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MOC3063M and VO3063-X006 maintain active product status and full regulatory compliance (ROHS3). The MOC3063M is recommended for applications with standard isolation requirements and established supply chain preferences. The VO3063-X006 is suitable for applications requiring enhanced isolation voltage margins, improved dV/dt performance, or extended low-temperature operation. Both components carry appropriate safety certifications (CSA, FIMKO, UL for MOC3063M; cUR, UR for VO3063-X006) and are classified under ECCN EAR99 with identical HTSUS coding (8541.49.8000). Selection between these parts should be based on specific application isolation voltage requirements and operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can the VO3063-X006 be used as a direct replacement for the MOC3063M in existing designs?

A: Yes. Both components share identical package geometry (6-DIP), output type (triac), zero-crossing functionality, and critical electrical parameters (LED trigger current, forward voltage, off-state voltage). The VO3063-X006 provides enhanced specifications without reducing compatibility.

Q: What are the key differences between these optoisolators?

A: The VO3063-X006 provides higher isolation voltage (5300Vrms vs. 5000Vrms), improved static dV/dt rating (1.5kV/µs vs. 1kV/µs), lower hold current (200µA vs. 400µA typical), higher forward current capability (60mA vs. 50mA maximum), and extended operating temperature range (-55°C to 100°C vs. -40°C to 100°C).

Q: Are there any pin compatibility concerns?

A: No. Both components use the standard 6-DIP package with 0.400" (10.16mm) spacing, ensuring direct pin-for-pin compatibility in through-hole applications.

Q: Which certifications apply to each part?

A: The MOC3063M carries CSA, FIMKO, and UL approvals. The VO3063-X006 carries cUR and UR approvals. Both are ROHS3 compliant and classified as REACH Unaffected (VO3063-X006) or equivalent status.

Q: Should I select based on isolation voltage alone?

A: No. While isolation voltage is important, selection should also consider operating temperature requirements, dV/dt performance needs, and forward current demands specific to your application circuit design.
