MOC8105300W Equivalent & Substitute Parts

Part Overview

The MOC8105300W is a high-voltage optoisolator with transistor output manufactured by onsemi, rated for 5300Vrms isolation voltage in a 6-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part provides single-channel isolation with 50mA output current capability and operates across the industrial temperature range of -55°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC8105300W is determined by the following critical parameters:

• Package compatibility: 6-DIP (0.400", 10.16mm) form factor for direct board-level replacement
• Output type: Transistor output configuration
• Number of channels: Single-channel isolation
• Output current capability: 50mA per channel minimum
• Vce saturation: 400mV maximum
• Operating temperature range: Support for -55°C to 100°C or compatible subset
• Isolation voltage: Minimum 4170Vrms for applications not requiring the full 5300Vrms rating

The substitute parts identified maintain functional equivalence within these electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

CNY17F2TVM (onsemi): This part is actively manufactured and maintains compatibility with the MOC8105300W across all critical electrical parameters including output current (50mA), Vce saturation (400mV), and package form factor. The isolation voltage of 4170Vrms is lower than the original specification; this part is suitable for applications where the full 5300Vrms isolation is not required. The operating temperature range extends to -40°C minimum, which covers most industrial applications but excludes extreme low-temperature environments. RoHS3 compliance provides regulatory alignment for modern manufacturing standards.

MOC8105G (Isocom Components 2004 LTD): This part maintains the full operating temperature range (-55°C to 100°C) and identical output specifications (50mA, 400mV Vce saturation, 30V maximum output voltage). However, the isolation voltage specification of 7.5Vpk differs significantly from the original 5300Vrms rating and lacks detailed current transfer ratio data. This part is suitable only for applications where isolation voltage requirements are substantially lower than the original design specification. RoHS3 compliance is provided.

Frequently Asked Questions (FAQ)

Q: Can CNY17F2TVM replace MOC8105300W in all applications?

A: CNY17F2TVM is electrically compatible for output stage operation (50mA current, 400mV saturation, 6-DIP package). The isolation voltage is 4170Vrms versus 5300Vrms. Substitution is valid only when the application isolation requirement does not exceed 4170Vrms. The minimum operating temperature is -40°C instead of -55°C.

Q: What is the primary difference between MOC8105G and the original part?

A: MOC8105G maintains identical output electrical characteristics and the full -55°C to 100°C temperature range. The isolation voltage specification (7.5Vpk) is substantially different from the original 5300Vrms rating. Current transfer ratio specifications are not provided for MOC8105G.

Q: Are all substitute parts available in the same 6-DIP package?

A: Yes. All three parts use the 6-DIP (0.400", 10.16mm) package with through-hole mounting, enabling direct board-level replacement without layout modification.

Q: Which substitute part has the best regulatory compliance?

A: Both CNY17F2TVM and MOC8105G carry RoHS3 compliance certification. The original MOC8105300W compliance status is not specified in available documentation.

Q: What is the minimum isolation voltage requirement for selecting a substitute?

A: The application circuit must define the minimum isolation voltage requirement. CNY17F2TVM provides 4170Vrms isolation. If the design requires 5300Vrms or higher, neither substitute meets this specification based on provided data.
