VO4156D-X007T Equivalent & Substitute Parts

Part Overview

The VO4156D-X007T is a Vishay Semiconductor Opto Division optoisolator with triac output, rated for 5300Vrms isolation voltage and designed for single-channel applications in 6-SMD surface mount packaging. This component features zero-crossing detection and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VO4156D-X007T is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Output Type: Triac
• Package / Case: 6-SMD, Gull Wing
• Mounting Type: Surface Mount
• Zero Crossing Circuit: Yes
• Number of Channels: 1
• Voltage - Off State: 600 V
• Current - Hold (Ih): 500µA

Acceptable Parameter Variations:

• Voltage - Isolation: Substitute parts rated at 4170Vrms are acceptable as they meet or exceed the isolation requirements for applications designed for the VO4156D-X007T
• Static dV/dt (Min): Substitute parts with 600V/µs or 1kV/µs ratings are acceptable, as these exceed the minimum requirement
• Current - LED Trigger (Ift) (Max): Substitute parts with ratings of 5mA, 10mA, or 15mA are acceptable
• Operating Temperature: Substitute parts with -40°C ~ 85°C range are acceptable for most applications
• Voltage - Forward (Vf) (Typ): 1.3V is acceptable as a minor variation from 1.2V

The substitute parts listed below maintain functional equivalence through these parameters while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status from onsemi or Fairchild Semiconductor, ensuring long-term availability and supply chain continuity. Selection among the substitute options should be based on packaging requirements and current trigger specifications:

Packaging Selection:

• Tube packaging: MOC3061SM, MOC3062SM, MOC3063SM, MOC3162SM
• Tape & Reel (TR) packaging: MOC3061SR2M, MOC3063SR2M, MOC3163SR2M

Current Trigger (Ift) Considerations:

• MOC3061SM and MOC3061SR2M: 15mA maximum trigger current
• MOC3062SM and MOC3062SR2M: 10mA maximum trigger current
• MOC3063SM and MOC3063SR2M: 5mA maximum trigger current
• MOC3162SM: 10mA maximum trigger current
• MOC3163SR2M: 5mA maximum trigger current

All substitute parts comply with ROHS3 requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can MOC306x series parts directly replace the VO4156D-X007T?

A: Yes. The MOC306x series (MOC3061, MOC3062, MOC3063) and MOC316x series (MOC3162, MOC3163) maintain functional equivalence through identical package geometry (6-SMD, Gull Wing), output type (Triac), zero-crossing detection, single-channel configuration, and hold current specifications. The 4170Vrms isolation rating of substitute parts is acceptable for applications designed for the VO4156D-X007T.

Q: What is the difference between MOC3063SM and MOC3063SR2M?

A: Both parts are electrically identical. The difference is packaging: MOC3063SM is supplied in Tube packaging, while MOC3063SR2M is supplied in Tape & Reel (TR) format. Selection depends on manufacturing process requirements and volume handling.

Q: How do the current trigger specifications affect substitution?

A: The VO4156D-X007T has a maximum LED trigger current (Ift) of 1.6mA. Substitute parts with higher Ift ratings (5mA, 10mA, or 15mA) require proportionally higher input current to activate the optoisolator. Circuit design must accommodate these higher trigger current requirements. MOC3063 and MOC3163 variants with 5mA ratings provide the closest match to the original specification.

Q: Are all substitute parts RoHS3 compliant?

A: All onsemi-manufactured substitute parts (MOC3061SM, MOC3061SR2M, MOC3062SM, MOC3063SM, MOC3063SR2M, MOC3162SM, MOC3163SR2M) are ROHS3 compliant. The Fairchild MOC3062SR2M does not specify RoHS status in the provided data.

Q: What is the operating temperature range difference?

A: The VO4156D-X007T operates from -55°C to 100°C, while all substitute parts operate from -40°C to 85°C. Applications requiring operation below -40°C or above 85°C cannot use these substitutes without design modification or thermal management considerations.

Q: Do all substitute parts have the same dV/dt rating?

A: No. MOC3061, MOC3062, and MOC3063 variants have a Static dV/dt (Min) of 600V/µs, while MOC3162 and MOC3163 variants have 1kV/µs. The VO4156D-X007T specifies 5kV/µs. Applications sensitive to dV/dt performance should evaluate circuit requirements before substitution.
