MOC3063FR2M Equivalent & Substitute Parts

Part Overview

The MOC3063FR2M is a 7.5kV isolation optoisolator with triac output manufactured by onsemi in a 6-SMD surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The part provides galvanic isolation suitable for AC power control applications with zero-crossing detection capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC3063FR2M is determined by the following critical parameters: output type (triac), number of channels (1), zero-crossing circuit presence, voltage isolation rating, off-state voltage (600V), LED trigger current (5mA maximum), hold current, forward current capability (60mA), and physical package compatibility.

The substitute parts are grouped into two categories:

Category 1: Surface Mount Direct Equivalent MOC3063SR2M maintains the same manufacturer (onsemi), output type (triac), channel count (1), zero-crossing circuit, and 6-SMD surface mount package. This part differs in isolation voltage specification (4170Vrms versus 7500Vpk) and product status (active versus obsolete).

Category 2: Through-Hole Alternatives Q3062 and Q3063 from QT Brightek provide triac output with zero-crossing detection in 6-DIP through-hole packages. Both maintain 1-channel configuration, 600V off-state voltage, and 60mA forward current capability. These parts differ in mounting technology (through-hole versus surface mount) and isolation voltage ratings (5000Vrms).

Parameter Comparison

Engineering Selection Recommendations

For Surface Mount Applications: MOC3063SR2M is the primary active substitute for MOC3063FR2M. Both parts maintain identical 6-SMD surface mount packaging and are manufactured by onsemi. The MOC3063SR2M carries active product status with UL approval and ROHS3 compliance. The isolation voltage differs (4170Vrms versus 7500Vpk); applications requiring the higher 7500Vpk isolation rating cannot use this substitute.

For Through-Hole Applications: Q3063 provides the closest functional match among through-hole options, maintaining the 5mA LED trigger current specification identical to the MOC3063FR2M. Q3063 is manufactured by QT Brightek with active product status, UR and VDE approvals, and ROHS3 compliance. The 6-DIP package requires PCB redesign from the original surface mount layout.

Q3062 offers an alternative through-hole solution with identical isolation voltage (5000Vrms) and forward current (60mA) but specifies 10mA maximum LED trigger current, requiring higher input drive current compared to the MOC3063FR2M.

All substitute parts maintain the critical functional parameters: single-channel triac output, zero-crossing detection, 600V off-state voltage, and 60mA forward current capability.

Frequently Asked Questions (FAQ)

Q: Can MOC3063SR2M directly replace MOC3063FR2M in existing designs? A: MOC3063SR2M is suitable for designs where the 4170Vrms isolation voltage meets application requirements. Both parts share identical 6-SMD surface mount packaging, LED trigger current (5mA), hold current (500µA typical), and forward current (60mA). Designs requiring the higher 7500Vpk isolation rating of the original part cannot use this substitute.

Q: What are the key differences between surface mount and through-hole substitutes? A: MOC3063SR2M maintains surface mount technology (6-SMD) identical to the original part. Q3062 and Q3063 require through-hole mounting (6-DIP package), necessitating PCB redesign. Through-hole parts offer wider operating temperature ranges (-55°C to 100°C versus -40°C to 85°C) and different approval certifications (UR, VDE versus UL).

Q: Which substitute should be selected for high isolation voltage applications? A: If the application requires isolation voltage above 5000Vrms, none of the listed substitutes meet this requirement. MOC3063FR2M specified 7500Vpk isolation; MOC3063SR2M provides 4170Vrms, and Q3062/Q3063 provide 5000Vrms. Alternative components with higher isolation ratings must be evaluated.

Q: Are all substitute parts RoHS compliant? A: MOC3063SR2M, Q3062, and Q3063 are all ROHS3 compliant. The original MOC3063FR2M RoHS status is not specified in available documentation.

Q: What is the LED trigger current difference between Q3062 and Q3063? A: Q3062 specifies 10mA maximum LED trigger current, while Q3063 specifies 5mA maximum, matching the original MOC3063FR2M. Applications with limited input drive capability should select Q3063 to maintain the lower trigger current requirement.
