Substitute Part Grouping Explanation

The MOC3041TVM qualifies as a direct substitute for the MOC3041TM based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Triac output type with zero-crossing detection circuit
• Isolation voltage of 4170Vrms
• Off-state voltage of 400 V
• Static dV/dt minimum of 1kV/µs
• LED trigger current (Ift) maximum of 15mA
• Hold current (Ih) of 400µA typical
• Forward voltage (Vf) of 1.25V typical
• DC forward current (If) maximum of 60 mA
• Operating temperature range of -40°C to 85°C
• 6-DIP through-hole package configuration

The MOC3041TVM maintains all specified electrical characteristics and physical dimensions, enabling direct pin-for-pin replacement in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The MOC3041TVM is the appropriate substitute for the obsolete MOC3041TM. The substitute part maintains active product status with onsemi, ensuring continued availability and manufacturing support. The MOC3041TVM carries expanded regulatory approvals including IEC/EN/DIN certification in addition to UL approval, providing broader compliance coverage for international applications. Both parts share identical electrical specifications and package geometry, supporting direct replacement without circuit modification. The transition from MOC3041TM to MOC3041TVM is driven by product lifecycle management rather than technical limitation, with the substitute offering equivalent performance and enhanced regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can MOC3041TVM replace MOC3041TM in existing designs? A: Yes. The MOC3041TVM is a direct substitute with identical electrical parameters, isolation voltage, triac output characteristics, and 6-DIP package dimensions. Pin-for-pin replacement is supported without circuit redesign.

Q: What is the primary difference between these parts? A: The MOC3041TM is obsolete while the MOC3041TVM maintains active production status. The MOC3041TVM also includes expanded regulatory certifications (IEC/EN/DIN) beyond the UL approval of the MOC3041TM.

Q: Are there packaging differences between MOC3041TM and MOC3041TVM? A: The MOC3041TM is supplied in standard packaging while the MOC3041TVM is supplied in tube packaging. Both use identical 6-DIP through-hole package geometry with 0.400" (10.16mm) spacing, ensuring mechanical compatibility.

Q: What electrical parameters determine substitution validity for optoisolator triac devices? A: Critical parameters include isolation voltage (4170Vrms), off-state voltage (400 V), zero-crossing circuit presence, LED trigger current (15mA max), hold current (400µA typical), forward voltage (1.25V typical), DC forward current (60 mA max), and operating temperature range (-40°C to 85°C).

Q: Is the MOC3041TVM compliant with current regulatory standards? A: Yes. The MOC3041TVM carries REACH Unaffected status and maintains EAR99 export classification. It holds UL approval and expanded IEC/EN/DIN certifications, supporting compliance requirements for industrial and international applications.
