Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOC3041FR2VM is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Output Type: Triac
• Number of Channels: 1
• Zero Crossing Circuit: Yes
• Mounting Type: Surface Mount
• Package / Case: 6-SMD, Gull Wing
• Voltage - Off State: 400 V
• Current - LED Trigger (Ift) (Max): 15mA
• Current - Hold (Ih) (Typ): 400µA
• Current - DC Forward (If) (Max): 60 mA

Isolation Voltage Consideration: The MOC3041FR2VM specifies 7500Vpk isolation. Substitute parts must maintain isolation voltage ratings that satisfy the application requirements. The MOC3041SR2VM provides 4170Vrms isolation, which represents a lower isolation specification and may be suitable only for applications where the reduced isolation rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The MOC3041SR2VM is the identified substitute for the obsolete MOC3041FR2VM. Both components share the same base product number (MOC304) and maintain identical electrical characteristics for LED trigger current, hold current, forward current, off-state voltage, and package configuration.

The MOC3041SR2VM offers the advantage of active product status, ensuring continued availability and manufacturing support. This part is ROHS3 compliant and includes specified operating temperature range (-40°C ~ 85°C), providing additional design documentation compared to the obsolete MOC3041FR2VM.

The primary design consideration is the isolation voltage specification. The MOC3041FR2VM provides 7500Vpk isolation, while the MOC3041SR2VM provides 4170Vrms isolation. Applications requiring the higher isolation rating of the original part must evaluate whether the substitute's isolation specification meets system-level safety and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MOC3041SR2VM directly replace MOC3041FR2VM in all applications?

A: Both parts share identical triac output configuration, single channel design, zero-crossing detection, and current specifications. The primary difference is isolation voltage rating. Direct replacement is possible only if the application's isolation voltage requirement is satisfied by the 4170Vrms specification of the MOC3041SR2VM.

Q: What is the significance of the isolation voltage difference between these parts?

A: Isolation voltage determines the maximum voltage differential that can be safely applied across the optoisolator's isolation barrier. The MOC3041FR2VM specifies 7500Vpk, while the MOC3041SR2VM specifies 4170Vrms. Applications designed for the higher isolation rating require evaluation before substitution.

Q: Are the package and mounting specifications identical?

A: Yes. Both the MOC3041FR2VM and MOC3041SR2VM use 6-SMD, Gull Wing surface mount packages with identical pin configurations and footprints.

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

A: The MOC3041FR2VM is classified as obsolete, indicating discontinued manufacturing and limited availability. The MOC3041SR2VM is active, ensuring ongoing production, supply chain availability, and manufacturer support for technical documentation and quality assurance.

Q: Are there compliance or regulatory differences between these parts?

A: The MOC3041SR2VM is ROHS3 compliant with specified approval agencies (IEC/EN/DIN, UL). The MOC3041FR2VM does not specify these compliance certifications. Both parts are REACH unaffected and carry the same ECCN and HTSUS classifications.
