MOC8102X Equivalent & Substitute Parts

Part Overview

The MOC8102X is an optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5300Vrms with a single channel configuration in a 6-DIP package. The part is currently in active production status with 1412 units available in stock.

Substitute parts become necessary when the MOC8102X reaches end-of-life, when supply constraints occur, or when design flexibility is required across manufacturing sources. The MOC8102 from onsemi represents a direct functional equivalent, though it carries an obsolete product status designation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOC8102X is determined by the following critical parameters:

• Voltage isolation rating of 5300Vrms minimum
• Single channel configuration
• Current transfer ratio range of 73% to 117% @ 10mA
• Transistor output type
• Maximum output voltage of 30V
• Output current capability of 50mA per channel
• 6-DIP through-hole package format
• Operating temperature range of -55°C to 100°C

The MOC8102 from onsemi meets all these substitution criteria. Both parts share identical isolation voltage, channel count, current transfer ratio specifications, output characteristics, and package geometry. The through-hole mounting type and temperature operating range are equivalent across both components.

Parameter Comparison

Engineering Selection Recommendations

The MOC8102 from onsemi is a direct functional substitute for the MOC8102X. Both components are REACH Unaffected and classified under ECCN EAR99, meeting equivalent regulatory requirements.

The primary consideration is product status: the MOC8102X maintains active production status with current inventory availability, while the MOC8102 carries an obsolete designation. For new designs or long-term production requirements, the MOC8102X is the preferred selection due to its active status and established supply chain.

The MOC8102 may be selected when supply of the MOC8102X is constrained or when existing inventory of the onsemi variant is available. Both components satisfy identical electrical and mechanical requirements for applications requiring 5300Vrms isolation with single-channel transistor output in 6-DIP through-hole configuration.

Frequently Asked Questions (FAQ)

Q: Can the MOC8102 replace the MOC8102X in existing designs?

A: Yes. Both components share identical electrical specifications including isolation voltage, current transfer ratio, output voltage and current ratings, and operating temperature range. The 6-DIP through-hole package geometry is identical, enabling direct pin-compatible substitution.

Q: What is the significance of the MOC8102 being marked obsolete?

A: Obsolete status indicates the onsemi MOC8102 is no longer in active production. This affects long-term supply availability and may impact lead times. The MOC8102X from Isocom remains in active production and is the recommended choice for new designs requiring sustained component availability.

Q: Are there differences in rise and fall times between these parts?

A: The MOC8102X specifies rise and fall times of 2µs and 2µs respectively. The MOC8102 specifies 1µs and 2µs. Both values fall within acceptable ranges for typical optoisolator applications, though the onsemi variant exhibits slightly faster rise time characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MOC8102X and MOC8102 are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: Is the 6-DIP package identical between manufacturers?

A: Yes. Both components use the 6-DIP (0.300", 7.62mm) package format with through-hole mounting. PCB footprints and land patterns are identical, supporting direct mechanical substitution.
