MOC119W Equivalent & Substitute Parts

Part Overview

The MOC119W is a 5300Vrms isolation optoisolator with Darlington output manufactured by onsemi in a 6-DIP through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The MOC119W provides single-channel optical isolation suitable for applications requiring high voltage isolation with DC input and Darlington output configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC119W is determined by the following critical parameters:

• Voltage - Isolation: 5300Vrms minimum requirement
• Package / Case: 6-DIP through-hole form factor
• Output Type: Darlington configuration
• Number of Channels: Single channel
• Voltage - Output (Max): 30V or higher
• Current - Output / Channel: 150mA or higher
• Operating Temperature Range: -55°C to 100°C or equivalent
• Input Type: DC

Substitute parts are grouped into two categories based on isolation voltage and output current specifications:

Group 1 - Direct Isolation Voltage Match (5300Vrms): ISPD60G, ISPD61G, ISPD62G, ISPD63G, ISPD64G, ISPD65G, and TIL119G maintain the same 5300Vrms isolation voltage as the MOC119W with identical 6-DIP package dimensions.

Group 2 - Lower Isolation Voltage (4170Vrms): MOC8021M provides reduced isolation voltage but maintains Darlington output and 6-DIP package configuration with higher output voltage capability (50V).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (5300Vrms Isolation Match): ISPD61G, ISPD62G, ISPD64G, and ISPD65G are preferred substitutes for the MOC119W. These parts maintain identical isolation voltage, package dimensions, and operating temperature range. All are manufactured by Isocom Components 2004 LTD with active product status and ROHS3 compliance. Selection among these four should be based on current transfer ratio requirements specific to the application.

Alternative Substitute (5300Vrms, Lower Output Current): TIL119G provides 5300Vrms isolation and identical package dimensions but specifies 30mA maximum output current compared to the MOC119W's 150mA. This part is suitable only for applications with reduced output current requirements.

Secondary Substitute (Lower Isolation Voltage): MOC8021M offers 4170Vrms isolation, which is lower than the MOC119W's 5300Vrms specification. This part is suitable only when the application isolation voltage requirement is 4170Vrms or lower. MOC8021M provides higher output voltage capability (50V) and higher current transfer ratio (1000% @ 10mA) but operates at a reduced minimum temperature of -40°C.

Package Consideration: MOC8021M uses a 6-DIP (0.300", 7.62mm) package, which differs from the MOC119W's 6-DIP (0.400", 10.16mm) package. PCB layout verification is required before substitution.

Frequently Asked Questions (FAQ)

Q: Can ISPD60G or ISPD63G be used as direct replacements for MOC119W?

A: ISPD60G and ISPD63G maintain the same 5300Vrms isolation voltage and 6-DIP package as the MOC119W. However, both specify 100% current transfer ratio @ 1mA, which differs from the MOC119W's 300% @ 10mA specification. Substitution is valid only if the application does not require the higher current transfer ratio of the original part.

Q: What is the key difference between MOC8021M and the MOC119W?

A: MOC8021M operates at 4170Vrms isolation voltage compared to MOC119W's 5300Vrms. Additionally, MOC8021M uses a 6-DIP (0.300", 7.62mm) package versus the MOC119W's 6-DIP (0.400", 10.16mm) package. MOC8021M is suitable only for applications where 4170Vrms isolation is sufficient and PCB layout accommodates the smaller package footprint.

Q: Are all Isocom ISPD6x series parts interchangeable with MOC119W?

A: ISPD60G through ISPD65G all maintain 5300Vrms isolation and identical 6-DIP (0.400", 10.16mm) package dimensions. They differ in current transfer ratio specifications. Selection should be based on the specific current transfer ratio requirement of the application circuit.

Q: Why is TIL119G not recommended as a primary substitute?

A: TIL119G specifies 30mA maximum output current, which is significantly lower than the MOC119W's 150mA specification. This part is suitable only for applications with reduced output current requirements. Additionally, current transfer ratio is not specified for TIL119G.

Q: What compliance certifications should be verified for substitute parts?

A: All active substitute parts (MOC8021M and ISPD series) are ROHS3 compliant and REACH unaffected. The MOC119W's compliance status is not specified due to its obsolete status. Verify compliance requirements with your specific application standards before final part selection.
