MOC3062 Equivalent & Substitute Parts

Part Overview

The MOC3062 is an optoisolator with triac output designed for applications requiring galvanic isolation and zero-crossing detection. Manufactured by Isocom Components 2004 LTD, this component provides 5300Vrms isolation voltage with a single triac channel in a 6-DIP package. The part is currently active in production with 2482 units in stock. Alternative models may be required due to supply constraints, regional availability, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC3062 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5300Vrms (mandatory match)
• Output Configuration: Triac output with zero-crossing detection
• Channel Count: Single channel
• Package Type: 6-DIP through-hole form factor
• Electrical Characteristics: LED trigger current, hold current, forward voltage, and DC forward current within acceptable ranges for the application
• Compliance: RoHS3 compliance and recognized approval agencies (UL, VDE, cUR, UR)

The VO3062 manufactured by Vishay Semiconductor Opto Division meets these substitution criteria with equivalent isolation voltage, triac output topology, zero-crossing functionality, and identical package configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the MOC3062 and VO3062 are active production components with ROHS3 compliance. Selection between these parts should be based on:

• Supply Availability: MOC3062 has 2482 units in stock; VO3062 has 3300 units in stock
• Certification Requirements: Verify that cUR and UR certifications meet application requirements if UL or VDE certification is mandated
• Electrical Performance: The VO3062 provides enhanced static dV/dt rating (1.5kV/µs vs 600V/µs) and wider operating temperature range (-55°C to 100°C vs -40°C to 100°C), which may benefit noise-sensitive or extreme-temperature applications
• Packaging: Both components use identical 6-DIP through-hole packaging with no PCB layout modifications required

Frequently Asked Questions (FAQ)

Q: Can the VO3062 directly replace the MOC3062 in existing designs?

A: Yes. Both components share identical isolation voltage (5300Vrms), triac output topology, zero-crossing detection, single-channel configuration, and 6-DIP package footprint. The VO3062 meets or exceeds the electrical specifications of the MOC3062.

Q: What are the differences in approval certifications?

A: The MOC3062 carries UL and VDE approvals, while the VO3062 carries cUR and UR approvals. Verify that the certifications required by your application and regional standards are met by the selected part.

Q: Does the VO3062's higher static dV/dt rating affect compatibility?

A: No. The VO3062's 1.5kV/µs static dV/dt rating exceeds the MOC3062's 600V/µs specification, providing improved noise immunity without requiring design changes.

Q: Are there any temperature range considerations?

A: The VO3062 operates from -55°C to 100°C compared to the MOC3062's -40°C to 100°C range. If your application requires operation below -40°C, the VO3062 is the appropriate selection.

Q: Is PCB layout modification required when substituting these parts?

A: No. Both components use the 6-DIP (0.300", 7.62mm) through-hole package with identical pinout and footprint compatibility.
