Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOC8102300 is determined by the following critical parameters:

Primary Substitution Criteria:

• Package / Case: 6-DIP (0.300", 7.62mm) — mechanical and electrical interface compatibility
• Input Type: DC — signal input configuration
• Output Type: Transistor — output stage topology
• Number of Channels: 1 — channel count
• Voltage - Isolation: 5300Vrms minimum — galvanic isolation rating
• Current - Output / Channel: 50mA minimum — output current capability
• Voltage - Output (Max): 30V minimum — maximum output voltage rating
• Operating Temperature: -55°C ~ 100°C minimum range — thermal operating envelope

Secondary Compatibility Parameters:

• Current Transfer Ratio range overlap
• Turn On / Turn Off Time specifications
• Vce Saturation characteristics

Substitute parts must satisfy all primary criteria to ensure direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

MOC8102 (onsemi): Direct functional equivalent to MOC8102300. Identical electrical specifications across all critical parameters including isolation voltage (5300Vrms), current transfer ratio range (73%-117%), output voltage rating (30V), and operating temperature range (-55°C ~ 100°C). Both parts share obsolete product status. Selection of MOC8102 provides equivalent performance with no circuit modifications required.

CNY17F2VM (onsemi): Partial substitute with design considerations. Meets primary substitution criteria for package (6-DIP), input type (DC), output type (Transistor), channel count (1), and output current (50mA). However, isolation voltage is reduced to 4170Vrms compared to 5300Vrms, and maximum output voltage is increased to 70V. Operating temperature range is narrower (-40°C ~ 100°C versus -55°C ~ 100°C). Rise/Fall time is slower (4µs, 4.6µs versus 1µs, 2µs). CNY17F2VM is active product status with RoHS3 compliance. Selection requires circuit validation for isolation voltage adequacy and thermal operating envelope.

Frequently Asked Questions (FAQ)

Q: Can MOC8102 directly replace MOC8102300 without circuit modifications?

A: Yes. MOC8102 is electrically and mechanically identical to MOC8102300 across all specified parameters. Both are 6-DIP through-hole packages with 5300Vrms isolation, 73%-117% current transfer ratio, 30V maximum output voltage, and -55°C ~ 100°C operating temperature. Direct substitution is supported.

Q: Is CNY17F2VM a suitable replacement for MOC8102300?

A: CNY17F2VM meets the primary package and functional requirements (6-DIP, DC input, transistor output, 50mA output current). However, three parameters differ: isolation voltage is 4170Vrms (lower than 5300Vrms), maximum output voltage is 70V (higher than 30V), and operating temperature minimum is -40°C (higher than -55°C). Circuit validation is required to confirm isolation voltage adequacy for the application and thermal operating envelope compatibility.

Q: What is the significance of the 6-DIP package specification?

A: The 6-DIP (0.300", 7.62mm) package defines the physical footprint and pin configuration. All listed substitutes use identical 6-DIP packaging, ensuring mechanical compatibility with existing PCB layouts and through-hole assembly processes without modification.

Q: Why is product status (Obsolete vs. Active) relevant for substitution?

A: MOC8102300 and MOC8102 are both obsolete, indicating discontinued manufacturing. CNY17F2VM is active product status, meaning it remains in production with ongoing manufacturer support and availability. For long-term supply chain planning, active products provide greater procurement reliability.

Q: How do current transfer ratio specifications affect substitution?

A: Current transfer ratio (CTR) defines the ratio of output current to input current. MOC8102300 and MOC8102 specify 73%-117% @ 10mA, while CNY17F2VM specifies 63%-125% @ 10mA. Both ranges overlap and support similar input-to-output current relationships. Circuit designs accounting for CTR variation within the specified range are compatible with all three parts.

Q: What is the impact of rise/fall time differences between MOC8102300 and CNY17F2VM?

A: MOC8102300 specifies 1µs rise and 2µs fall time (typical), while CNY17F2VM specifies 4µs rise and 4.6µs fall time (maximum). Slower switching speed in CNY17F2VM may affect high-frequency signal integrity. Applications with timing-critical requirements must validate CNY17F2VM performance against circuit specifications.
