Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC3063G is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating of 5300Vrms
• Triac output configuration with power capability
• Zero-crossing detection circuit presence
• Single-channel architecture
• 600V off-state voltage rating
• LED trigger current specification of 5mA maximum
• 6-DIP through-hole package format
• Forward voltage compatibility at 1.2V typical

The VO3063-X006 from Vishay Semiconductor Opto Division meets all substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both MOC3063G and VO3063-X006 are active production components with ROHS3 compliance and equivalent isolation voltage ratings. The VO3063-X006 provides enhanced performance specifications in static dV/dt rating (1.5kV/µs versus 600V/µs) and extended operating temperature range (-55°C to 100°C versus -40°C to 100°C). Both components carry appropriate regulatory approvals and maintain unlimited moisture sensitivity levels. Selection between these parts should be based on supply availability, lead time requirements, and specific application temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Can VO3063-X006 directly replace MOC3063G in existing designs?

A: Yes. Both components share identical isolation voltage (5300Vrms), triac output configuration, zero-crossing detection, package format (6-DIP), and LED trigger current specifications (5mA). Pin-to-pin compatibility is maintained for through-hole PCB mounting.

Q: What are the key differences between these parts?

A: The VO3063-X006 features a higher static dV/dt rating (1.5kV/µs versus 600V/µs), lower typical hold current (200µA versus 400µA), higher maximum DC forward current (60mA versus 50mA), and an extended operating temperature range (-55°C to 100°C versus -40°C to 100°C).

Q: Are both parts suitable for high-temperature applications?

A: The MOC3063G operates from -40°C to 100°C. The VO3063-X006 extends this range to -55°C to 100°C, providing broader temperature coverage for demanding environments.

Q: Do both parts require identical PCB footprints?

A: Yes. Both components use the 6-DIP (0.400", 10.16mm) package format with identical pin spacing and through-hole mounting requirements.

Q: What compliance certifications apply to both parts?

A: Both MOC3063G and VO3063-X006 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.49.8000.
