MOC3063 Equivalent & Substitute Parts

Part Overview

The MOC3063 is an optoisolator with triac output manufactured by Isocom Components 2004 LTD. This 6-pin DIP component provides galvanic isolation up to 5300Vrms with zero-crossing detection capability, designed for AC power control applications. The part is currently active in production with 130,200 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for procurement flexibility, design redundancy, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The VO3063 manufactured by Vishay Semiconductor Opto Division qualifies as a direct substitute based on the following critical parameters:

• Isolation voltage: 5300Vrms (identical)
• Output type: Triac output (identical functional classification)
• Zero crossing circuit: Present (identical)
• Number of channels: 1 (identical)
• Off state voltage: 600V (identical)
• LED trigger current: 5mA maximum (identical)
• Package / case: 6-DIP (0.300", 7.62mm) (identical mechanical form factor)
• Mounting type: Through Hole (identical)
• RoHS3 compliance: Both parts compliant
• REACH status: Both parts unaffected

Substitution is valid when these core electrical and mechanical parameters match across parts. The VO3063 maintains functional equivalence for applications requiring MOC3063 performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both MOC3063 and VO3063 are active production parts with full regulatory compliance. Selection between these parts should be based on:

• Approval agency requirements: MOC3063 carries UL and VDE approvals; VO3063 carries cUR and UR approvals. Verify which certifications are required for your application.
• Operating temperature range: VO3063 extends to -55°C minimum, providing wider low-temperature operation if required.
• Static dV/dt performance: VO3063 specifies 1.5kV/µs versus MOC3063 at 600V/µs. Higher dV/dt capability in VO3063 may provide improved noise immunity in high-speed switching environments.
• Current specifications: VO3063 supports higher maximum DC forward current (60mA vs 50mA) and lower typical hold current (200µA vs 400µA).
• Packaging: Both parts use identical 6-DIP through-hole form factor, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can VO3063 replace MOC3063 in existing designs? A: Yes. Both parts share identical isolation voltage (5300Vrms), output type (triac), zero-crossing circuit presence, channel count, off-state voltage, LED trigger current, and 6-DIP package form factor. Direct substitution is mechanically and electrically valid.

Q: What are the key differences between these parts? A: The VO3063 offers extended low-temperature operation (-55°C vs -40°C), higher static dV/dt rating (1.5kV/µs vs 600V/µs), lower typical hold current (200µA vs 400µA), and higher maximum DC forward current (60mA vs 50mA). Approval agencies differ: MOC3063 is UL/VDE certified; VO3063 is cUR/UR certified.

Q: Are there any PCB layout considerations when substituting? A: No. Both parts use identical 6-DIP (0.300", 7.62mm) through-hole packaging. PCB footprints, pin spacing, and mounting requirements are identical.

Q: Which part should I select for new designs? A: Selection depends on certification requirements and performance needs. Verify required approval agencies (UL/VDE vs cUR/UR) for your application. If extended low-temperature operation or higher dV/dt immunity is needed, VO3063 is the appropriate choice.

Q: Are both parts RoHS and REACH compliant? A: Yes. Both MOC3063 and VO3063 are ROHS3 compliant and REACH unaffected.
