MCT2TVM Optoisolator Equivalent & Substitute Parts

Part Overview

The MCT2TVM is a single-channel optoisolator transistor with base output manufactured by onsemi, rated for 7500Vpk isolation voltage in a 6-DIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The MCT2TVM provides DC input isolation with transistor output capable of 50mA per channel and 30V maximum output voltage, suitable for applications requiring galvanic isolation in industrial and consumer electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCT2TVM are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Single channel configuration (Number of Channels = 1)
• Transistor with base output type
• 6-DIP through-hole package (0.400", 10.16mm)
• DC input type
• Minimum current transfer ratio of 20% @ 10mA
• Vce saturation maximum of 400mV
• Operating temperature range encompassing -40°C to 100°C
• Moisture sensitivity level MSL 1 (Unlimited)

Isolation Voltage Consideration: The MCT2TVM specifies 7500Vpk isolation. Substitute parts with lower isolation ratings (5000Vrms) remain functionally compatible in applications where the lower isolation specification is acceptable. The 5000Vrms rating (approximately 7071Vpk) provides equivalent or superior isolation performance in most industrial applications.

Substitutes are grouped into two categories:

1. Direct Functional Equivalents - Parts meeting or exceeding all primary criteria with active product status
2. Compatible Alternatives - Parts with lower isolation voltage but meeting all other electrical and mechanical specifications

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - MCT2G (Isocom Components): MCT2G is the direct successor to MCT2TVM, sharing the same 7500Vpk isolation voltage specification and identical electrical characteristics. This part maintains active product status with ROHS3 compliance and is the preferred substitute for direct replacement in existing designs.

Secondary Recommendations - Everlight H11A Series (H11A2M-V, H11A3M-V, H11A5M-V): These parts provide active product status with ROHS3 compliance and extended operating temperature range (-55°C to 110°C). The 5000Vrms isolation rating is suitable for applications where the lower isolation specification meets system requirements. H11A5M-V offers the highest current transfer ratio (30% @ 10mA), providing improved switching characteristics. H11A4M-V is not recommended due to 10% minimum current transfer ratio, below the MCT2TVM specification.

Alternative Recommendation - LTV-702VM (Lite-On Inc.): LTV-702VM provides active product status with ROHS3 compliance and 5000Vrms isolation. This part offers the highest current transfer ratio range (40% to 320% @ 10mA) and 50mA output current matching the MCT2TVM specification. The 70V maximum output voltage exceeds the MCT2TVM requirement.

Compliance Consideration: All substitute parts carry ROHS3 compliance certification, suitable for applications requiring environmental compliance. The MCT2TVM REACH Unaffected status is superseded by the ROHS3 compliance of active substitute parts.

Frequently Asked Questions (FAQ)

Q: Can H11A2M-V, H11A3M-V, or H11A5M-V be used as direct replacements for MCT2TVM? A: Yes, these parts are mechanically and functionally compatible. All three share the 6-DIP package, single-channel transistor output configuration, and meet the 20% minimum current transfer ratio requirement. The 5000Vrms isolation rating is equivalent to approximately 7071Vpk, providing adequate isolation in most applications. Verify that your circuit design does not specifically require the 7500Vpk isolation specification.

Q: Why is MCT2G recommended over the Everlight H11A series? A: MCT2G maintains the identical 7500Vpk isolation voltage as the MCT2TVM, providing direct electrical equivalence without design modification. MCT2G is the designated successor within the MCT2 product series. The Everlight H11A series offers lower isolation voltage but remains compatible for applications where this specification is acceptable.

Q: What is the difference between H11A2M-V, H11A3M-V, and H11A5M-V? A: These parts differ only in current transfer ratio specification. H11A2M-V and H11A3M-V specify 20% minimum (matching MCT2TVM), while H11A5M-V specifies 30% minimum, providing faster switching response. H11A4M-V specifies 10% minimum and is not recommended for MCT2TVM replacement.

Q: Is the 6-DIP package pinout identical across all substitute parts? A: All substitute parts use the standard 6-DIP (0.400", 10.16mm) through-hole package. Verify pinout compatibility with your PCB design, as pin assignments may vary between manufacturers. Consult individual datasheets for specific pin configurations.

Q: Can I use LTV-702VM in place of MCT2TVM? A: Yes, LTV-702VM is mechanically and functionally compatible. It provides 5000Vrms isolation, 50mA output current matching the MCT2TVM, and active product status with ROHS3 compliance. The higher current transfer ratio range (40% to 320%) may provide improved performance in switching applications.

Q: What is the difference between Vpk and Vrms isolation voltage ratings? A: Vpk (peak voltage) and Vrms (root mean square voltage) represent different measurement standards for isolation voltage. 5000Vrms converts to approximately 7071Vpk, exceeding the MCT2TVM 7500Vpk specification. Parts rated in Vrms typically provide equivalent or superior isolation performance compared to Vpk ratings.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all active substitute parts (MCT2G, H11A2M-V, H11A3M-V, H11A4M-V, H11A5M-V, and LTV-702VM) carry ROHS3 compliance certification. The obsolete MCT2TVM carries REACH Unaffected status, which is superseded by ROHS3 compliance in active alternatives.
