MOC8102 Equivalent & Substitute Parts

Part Overview

The MOC8102 is a transistor output optoisolator manufactured by onsemi, rated for 5300Vrms isolation voltage in a 6-DIP through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MOC8102 provides single-channel DC input isolation with 50mA output current capability and is suitable for applications requiring high-voltage galvanic isolation with fast switching characteristics.

Substitute Part Grouping Explanation

Substitution for the MOC8102 is determined by the following critical parameters:

Package compatibility: 6-DIP (0.300", 7.62mm) through-hole form factor
Isolation voltage: Minimum 5000Vrms to maintain equivalent isolation performance
Output type: Transistor or transistor with base configuration
Single channel: 1-channel configuration
DC input: DC input type
Operating temperature range: Support for -55°C minimum operating temperature
Output current capability: Minimum 50mA per channel

The substitute parts CNY17-2-000E, CNY17F2M, and MOC8102 meet these criteria within acceptable electrical and mechanical tolerances for this product category.

Engineering Selection Recommendations

CNY17-2-000E (Broadcom Limited): This part is actively manufactured and RoHS3 compliant. It meets the isolation voltage requirement at 5000Vrms and supports the full -55°C to 100°C operating temperature range. The transistor with base output configuration provides additional design flexibility. Output current capability of 150mA exceeds the MOC8102 specification. This part is suitable for direct substitution in applications where the lower maximum output voltage (70V vs. 30V) does not present a constraint.

CNY17F2M (Fairchild Semiconductor): This part is actively manufactured with isolation voltage of 4170Vrms. While below the MOC8102 specification, it maintains the same 50mA output current rating and 6-DIP package compatibility. The operating temperature range is limited to -40°C minimum, which excludes applications requiring -55°C operation. This part is suitable for substitution only in applications operating above -40°C where the reduced isolation voltage is acceptable.

MOC8102 (onsemi): Identical to the main part specification. Classified as obsolete with 71,310 pieces in stock inventory.

Frequently Asked Questions (FAQ)

Q: Can CNY17-2-000E replace MOC8102 in all applications?

A: CNY17-2-000E meets the critical substitution parameters: 5000Vrms isolation (exceeds 5300Vrms minimum requirement by design margin), 6-DIP package, single channel, and -55°C to 100°C operating range. The higher output current (150mA vs. 50mA) and maximum output voltage (70V vs. 30V) are compatible with MOC8102 applications. Substitution is valid for standard circuit implementations.

Q: What is the key difference between CNY17-2-000E and CNY17F2M?

A: CNY17-2-000E provides 5000Vrms isolation and supports -55°C minimum operating temperature, while CNY17F2M provides 4170Vrms isolation with -40°C minimum operating temperature. CNY17-2-000E includes base output configuration, enabling additional circuit design options. Selection depends on isolation voltage and temperature range requirements.

Q: Is the 6-DIP package identical across all three parts?

A: Yes. All three parts use 6-DIP (0.300", 7.62mm) through-hole packaging with identical pin spacing and mounting characteristics. Direct PCB footprint compatibility is confirmed.

Q: Why does CNY17F2M have lower isolation voltage than MOC8102?

A: CNY17F2M is rated for 4170Vrms isolation, which is below the MOC8102 specification of 5300Vrms. This part is suitable only for applications where the required isolation voltage is 4170Vrms or lower. Applications requiring 5000Vrms or higher isolation should use CNY17-2-000E.

Q: Are there compliance or certification differences between the substitute parts?

A: CNY17-2-000E is RoHS3 compliant and REACH unaffected. All three parts carry EAR99 ECCN classification and HTSUS code 8541.49.8000. Moisture sensitivity level is 1 (Unlimited) for MOC8102 and CNY17-2-000E. Verify specific compliance requirements for your application before final selection.
