MCT2201S Equivalent & Substitute Parts

Part Overview

The MCT2201S is an optoisolator transistor with base output manufactured by onsemi, featuring 5300Vrms isolation voltage and single-channel configuration in 6-SMD surface mount packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The MCT2201S provides DC input with transistor output capability, suitable for applications requiring galvanic isolation with moderate current switching requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCT2201S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Single-channel configuration (Number of Channels = 1)
• Transistor output with base connection
• 6-SMD surface mount package with gull wing leads
• DC input type
• Vce saturation maximum of 400mV

Secondary Compatibility Criteria:

• Isolation voltage rating (minimum acceptable: 4170Vrms for reduced isolation margin applications)
• Current transfer ratio minimum of 100% @ 10mA
• Maximum output voltage of 30V or higher
• Operating temperature range encompassing -55°C to 100°C or compatible subset

The substitute parts identified maintain functional equivalence through matching output topology, package configuration, and core electrical characteristics. Isolation voltage variations reflect different application safety margins but remain within acceptable substitution parameters for equivalent circuit functionality.

Engineering Selection Recommendations

MCT2201SMT&R (Isocom Components 2004 LTD) - Preferred Substitute

The MCT2201SMT&R represents the primary substitute for MCT2201S applications. This part maintains identical package configuration (6-SMD, Gull Wing), matching output topology, and compatible operating temperature range (-55°C ~ 100°C). The component is actively manufactured and ROHS3 compliant, providing long-term supply assurance. Tape & Reel packaging supports automated assembly processes. The isolation voltage specification (7.5Vpk) differs from the original but remains suitable for equivalent circuit functionality.

MCT2201SM (Isocom Components 2004 LTD) - Alternative Substitute

The MCT2201SM offers identical electrical and mechanical characteristics to MCT2201SMT&R with bulk packaging. This configuration suits lower-volume applications or manual assembly processes. Active product status and ROHS3 compliance ensure availability and regulatory alignment.

H11AV1SM (Fairchild Semiconductor) - Secondary Substitute

The H11AV1SM provides functional equivalence with notable differences in isolation voltage (4170Vrms) and maximum output voltage (70V). Operating temperature range (-40°C ~ 100°C) excludes the lower temperature extreme of the original specification. This part is actively manufactured and suitable for applications where reduced isolation margin and extended output voltage capability are acceptable trade-offs.

Frequently Asked Questions (FAQ)

Q: Can MCT2201SMT&R directly replace MCT2201S in existing designs?

A: Yes. Both components share identical package configuration (6-SMD, Gull Wing), output topology (transistor with base), and operating temperature range (-55°C ~ 100°C). Electrical parameters including current transfer ratio, Vce saturation, and forward voltage are compatible. The isolation voltage specification differs (7.5Vpk vs. 5300Vrms), but this represents a design parameter variation rather than a functional incompatibility.

Q: What is the difference between MCT2201SM and MCT2201SMT&R?

A: Both parts are manufactured by Isocom Components 2004 LTD with identical electrical specifications and 6-SMD package configuration. The primary difference is packaging format: MCT2201SM is supplied in bulk, while MCT2201SMT&R is supplied in tape and reel format. Tape and reel packaging is optimized for automated pick-and-place assembly, while bulk packaging suits manual handling or lower-volume applications.

Q: Is H11AV1SM suitable for applications requiring 5300Vrms isolation?

A: No. The H11AV1SM provides 4170Vrms isolation voltage, which is lower than the MCT2201S specification. Applications with strict isolation voltage requirements should use MCT2201SM or MCT2201SMT&R instead. The H11AV1SM is appropriate for applications where 4170Vrms isolation meets design requirements.

Q: What compliance certifications apply to substitute parts?

A: MCT2201SM and MCT2201SMT&R are ROHS3 compliant with REACH unaffected status. H11AV1SM carries EAR99 export classification. All substitute parts maintain EAR99 classification matching the original MCT2201S.

Q: Are there packaging considerations when switching from MCT2201S to substitute parts?

A: All substitute parts maintain 6-SMD, Gull Wing surface mount configuration, ensuring PCB footprint compatibility. Tape and reel packaging (MCT2201SMT&R) requires compatible automated assembly equipment, while bulk packaging (MCT2201SM) suits manual or semi-automated processes. No PCB redesign is necessary for package migration.
