MCT2201SD Equivalent & Substitute Parts

Part Overview

The MCT2201SD is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 5300Vrms isolation rating. This component features a single channel configuration in a 6-SMD gull wing package with a 50mA output current capability and 400mV maximum saturation voltage. The MCT2201SD is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCT2201SD are identified based on the following critical parameters that determine functional equivalence:

• Output Type: Transistor with Base (all substitutes maintain this configuration)
• Number of Channels: Single channel (1 channel)
• Package / Case: 6-SMD, Gull Wing (physical and electrical compatibility)
• Mounting Type: Surface Mount
• Input Type: DC
• Moisture Sensitivity Level: 1 (Unlimited)
• Vce Saturation (Max): 400mV (all substitutes match this specification)

The substitute parts are grouped into two categories based on isolation voltage rating and product status:

Category 1 - Active onsemi Product (Lower Isolation Rating)

• H11AV1SR2M: Active product with 4170Vrms isolation (lower than MCT2201SD)

Category 2 - Active Isocom Components Products (Lower Isolation Rating)

• MCT2201SM: Active product with 7.5Vpk isolation rating
• MCT2201SMT&R: Active product with 7.5Vpk isolation rating (tape & reel packaging)

Engineering Selection Recommendations

H11AV1SR2M (onsemi)

The H11AV1SR2M is an active onsemi product maintaining the same manufacturer lineage as the MCT2201SD. This part is RoHS3 compliant and carries REACH Unaffected status. The primary consideration is the reduced isolation voltage rating of 4170Vrms compared to the MCT2201SD's 5300Vrms. The H11AV1SR2M features extended turn-on/turn-off times (15µs maximum) relative to the MCT2201SD (2µs typical) and higher maximum output voltage (70V versus 30V). Selection of this substitute requires confirmation that the lower isolation voltage meets circuit requirements.

MCT2201SM and MCT2201SMT&R (Isocom Components 2004 LTD)

Both MCT2201SM and MCT2201SMT&R are active products from Isocom Components 2004 LTD, with identical electrical specifications. These parts are RoHS3 compliant and REACH Unaffected. The critical distinction is the isolation voltage specification listed as 7.5Vpk, which represents a significant reduction from the MCT2201SD's 5300Vrms isolation rating. The MCT2201SMT&R differs from MCT2201SM only in packaging format (tape & reel versus tube). Both parts feature identical turn-on/turn-off times (10µs maximum) and maintain the same output voltage maximum (30V) and saturation voltage (400mV) as the MCT2201SD. Selection of these substitutes requires verification that the substantially lower isolation voltage is compatible with the application.

Frequently Asked Questions (FAQ)

Q: Can the H11AV1SR2M directly replace the MCT2201SD in all applications?

A: The H11AV1SR2M shares the same output type (transistor with base), package configuration (6-SMD gull wing), and saturation voltage specification (400mV maximum). However, the isolation voltage is reduced from 5300Vrms to 4170Vrms. Direct substitution is only appropriate for applications where the lower isolation voltage meets design requirements. Additionally, the extended switching times (15µs maximum versus 2µs typical) may affect circuit performance in timing-sensitive applications.

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

A: MCT2201SM is supplied in tube packaging, while MCT2201SMT&R is supplied in tape & reel (TR) format. The electrical specifications and performance characteristics are identical. Selection between these two variants depends on procurement and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: The H11AV1SR2M is RoHS3 compliant. Both MCT2201SM and MCT2201SMT&R are RoHS3 compliant. All substitute parts carry REACH Unaffected status, matching the MCT2201SD's regulatory classification.

Q: What is the significance of the isolation voltage difference between MCT2201SD and the substitute parts?

A: The MCT2201SD provides 5300Vrms isolation, while H11AV1SR2M provides 4170Vrms, and MCT2201SM/MCT2201SMT&R provide 7.5Vpk isolation. Isolation voltage determines the maximum voltage differential that can be safely applied across the optoisolator's isolation barrier. Applications requiring the full 5300Vrms isolation specification cannot use substitutes with lower ratings without circuit redesign or additional isolation measures.

Q: Can the MCT2201SM or MCT2201SMT&R be used in applications requiring the MCT2201SD's isolation voltage specification?

A: No. The 7.5Vpk isolation rating of MCT2201SM and MCT2201SMT&R is substantially lower than the MCT2201SD's 5300Vrms specification. These parts are not suitable for applications requiring high-voltage isolation unless the circuit design is modified to accommodate the reduced isolation capability.

Q: What are the operating temperature differences among these parts?

A: The MCT2201SD and MCT2201SM/MCT2201SMT&R both operate from -55°C to 100°C. The H11AV1SR2M operates from -40°C to 100°C, providing a narrower low-temperature range. Applications requiring operation below -40°C must use the MCT2201SD or Isocom variants.
