MOC8113 Equivalent & Substitute Parts

Part Overview

The MOC8113 is an optoisolator with transistor output manufactured by onsemi, featuring 5300Vrms isolation voltage in a 6-DIP package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations. The MOC8113 serves applications requiring high-voltage isolation with DC input and transistor output configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC8113 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Package / Case: 6-DIP (0.300", 7.62mm) form factor
• Mounting Type: Through Hole
• Input Type: DC
• Output Type: Transistor or Transistor with Base
• Number of Channels: 1
• Operating Temperature Range: -55°C ~ 100°C

Secondary Compatibility Criteria:

• Current Transfer Ratio (Min): 100% @ 10mA
• Voltage - Isolation: Minimum 3550Vrms (MOC8113 specifies 5300Vrms)
• Voltage - Output (Max): Minimum 30V
• Vce Saturation (Max): Maximum 400mV

The 4N35-000E from Broadcom Limited meets these criteria with compatible package, mounting, input/output types, and operating temperature range, though with lower isolation voltage and output voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

MOC8113 (onsemi): Obsolete status limits availability for new procurement. Existing inventory of 5680 pieces may support legacy system maintenance. Not recommended for new designs.

4N35-000E (Broadcom Limited): Active product status with 3942 pieces in stock. RoHS3 compliant. Suitable for applications where isolation voltage requirement is 3550Vrms or lower and output voltage requirement is 30V or lower. The 4N35-000E provides an active alternative with established supply chain support.

Selection between these parts depends on specific circuit isolation voltage and output voltage requirements. The MOC8113 provides higher isolation voltage (5300Vrms vs 3550Vrms) and higher maximum output voltage (70V vs 30V), while the 4N35-000E offers active product status and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 4N35-000E directly replace the MOC8113 in all applications?

A: Direct replacement depends on circuit requirements. Both parts share identical package (6-DIP), mounting type (Through Hole), input type (DC), and operating temperature range (-55°C ~ 100°C). However, the 4N35-000E has lower isolation voltage (3550Vrms vs 5300Vrms) and lower maximum output voltage (30V vs 70V). Replacement is valid only if the application isolation voltage requirement does not exceed 3550Vrms and output voltage requirement does not exceed 30V.

Q: What are the key differences between MOC8113 and 4N35-000E?

A: Primary differences include isolation voltage (MOC8113: 5300Vrms, 4N35-000E: 3550Vrms), maximum output voltage (MOC8113: 70V, 4N35-000E: 30V), output type (MOC8113: Transistor, 4N35-000E: Transistor with Base), fall time (MOC8113: 14µs, 4N35-000E: 3µs), and product status (MOC8113: Obsolete, 4N35-000E: Active).

Q: Is the 6-DIP package identical between MOC8113 and 4N35-000E?

A: Yes. Both parts use 6-DIP (0.300", 7.62mm) package with Through Hole mounting type, ensuring mechanical compatibility on PCB layouts designed for either component.

Q: What compliance certifications apply to these parts?

A: MOC8113 carries REACH Unaffected and EAR99 ECCN status. 4N35-000E is RoHS3 compliant with REACH Unaffected and EAR99 ECCN status.

Q: Why is MOC8113 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production by onsemi. Existing inventory remains available, but long-term supply cannot be guaranteed. The 4N35-000E represents an active alternative for new designs.
