MOC3033TM Equivalent & Substitute Parts

Part Overview

The MOC3033TM is an optoisolator with triac output manufactured by onsemi, designed for applications requiring galvanic isolation with direct AC load switching capability. This component features a 4170Vrms isolation voltage rating and integrated zero-crossing detection in a 6-DIP through-hole package. The MOC3033TM is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The VO3063-X006 from Vishay Semiconductor Opto Division qualifies as a functional substitute for the MOC3033TM based on the following substitution criteria:

Matching Parameters:

• Output Type: Triac (identical)
• Zero Crossing Circuit: Yes (identical)
• Number of Channels: 1 (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: 6-DIP (0.400", 10.16mm) (identical)
• Current - LED Trigger (Ift) (Max): 5mA (identical)
• Voltage - Forward (Vf) (Typ): 1.2V (compatible, within typical operating range)
• Current - DC Forward (If) (Max): 60 mA (identical)

Enhanced Parameters:

• Voltage - Isolation: 5300Vrms (exceeds 4170Vrms requirement)
• Voltage - Off State: 600 V (exceeds 250 V requirement)
• Static dV/dt (Min): 1.5kV/µs (exceeds 1kV/µs requirement)
• Current - Hold (Ih): 200µA (Typ) (lower than 400µA, favorable for reduced power consumption)
• Operating Temperature: -55°C ~ 100°C (wider range than -40°C ~ 85°C)
• Product Status: Active (currently manufactured and supported)

Parameter Comparison

Engineering Selection Recommendations

The VO3063-X006 is suitable as a direct substitute for the MOC3033TM in applications where the MOC3033TM is no longer available. The substitute part maintains identical functional characteristics for triac output, zero-crossing detection, channel count, and package form factor. All critical electrical parameters of the VO3063-X006 meet or exceed the specifications of the MOC3033TM, providing enhanced performance margins in isolation voltage, off-state voltage, and dV/dt rating.

The VO3063-X006 carries active product status with current manufacturing support, whereas the MOC3033TM is obsolete. The substitute part holds ROHS3 compliance certification and maintains REACH unaffected status, consistent with the original part's regulatory standing. Both components are classified under ECCN EAR99 and share identical HTSUS coding.

Frequently Asked Questions (FAQ)

Q: Can the VO3063-X006 be used as a direct pin-for-pin replacement for the MOC3033TM?

A: Yes. Both components use identical 6-DIP through-hole packaging with 0.400" (10.16mm) spacing. Pin configuration and functional pinout are compatible for direct substitution on existing PCB layouts without modification.

Q: What are the key differences between these two parts?

A: The VO3063-X006 provides enhanced electrical performance across multiple parameters: isolation voltage increases from 4170Vrms to 5300Vrms, off-state voltage increases from 250V to 600V, and static dV/dt rating increases from 1kV/µs to 1.5kV/µs. The VO3063-X006 also features lower typical hold current (200µA vs. 400µA) and a wider operating temperature range (-55°C to 100°C vs. -40°C to 85°C).

Q: Is the VO3063-X006 available in the same packaging format?

A: Yes. The VO3063-X006 is supplied in 6-DIP through-hole packaging identical to the MOC3033TM. The VO3063-X006 is available in tube packaging format.

Q: What is the product status difference, and why does it matter?

A: The MOC3033TM is classified as obsolete and is no longer in active production. The VO3063-X006 is classified as active and is currently manufactured with ongoing supplier support. For new designs or long-term procurement, the active status of the VO3063-X006 ensures continued availability and supply chain stability.

Q: Are there any compliance or certification differences?

A: Both parts maintain REACH unaffected status and EAR99 ECCN classification. The VO3063-X006 additionally carries ROHS3 compliance certification. Both components are approved by recognized agencies (MOC3033TM: UL; VO3063-X006: cUR, UR).

Q: Can the VO3063-X006 handle the same current and voltage levels as the MOC3033TM?

A: Yes. The VO3063-X006 meets all current specifications of the MOC3033TM (LED trigger current 5mA max, forward current 60mA max, hold current 200µA typical) and exceeds all voltage specifications, providing additional safety margin for isolation and off-state voltage performance.
