MOC8102W Equivalent & Substitute Parts

Part Overview

The MOC8102W is an optoisolator with transistor output manufactured by onsemi, featuring 5300Vrms isolation voltage and single-channel configuration in a 6-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MOC8102W serves applications requiring galvanic isolation with DC input and transistor output topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC8102W is determined by the following critical parameters:

• Isolation Voltage: 5300Vrms minimum requirement
• Number of Channels: Single channel configuration
• Output Type: Transistor output topology
• Package: 6-DIP form factor with 0.400" (10.16mm) pitch
• Current Transfer Ratio Range: 73% to 117% @ 10mA
• Maximum Output Current: 50mA per channel
• Operating Temperature Range: -55°C to 100°C
• Mounting Type: Through Hole

The substitute parts MOC8102-X006, MOC8102-X016, and MOC8102G meet these core electrical and mechanical requirements, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

MOC8102-X006 and MOC8102-X016 (Vishay Semiconductor Opto Division): Both variants are active products with ROHS3 compliance and identical electrical specifications. These represent the primary substitutes for the obsolete MOC8102W, offering equivalent isolation voltage, current transfer ratio range, and output characteristics. The Vishay variants feature slightly extended turn-off time (2.3µs versus 3µs) and reduced maximum forward current (60mA versus 100mA). Both are available in tube packaging with substantial inventory levels.

MOC8102G (Isocom Components 2004 LTD): This variant maintains the same 6-DIP package, output current rating, and operating temperature range. However, the isolation voltage specification differs (7.5Vpk versus 5300Vrms), and current transfer ratio parameters are not specified. This part is suitable for applications where the lower isolation voltage specification is acceptable. ROHS3 compliance is confirmed.

All substitute parts maintain through-hole mounting compatibility and identical package dimensions, enabling direct PCB layout compatibility with the original MOC8102W design.

Frequently Asked Questions (FAQ)

Q: Can MOC8102-X006 and MOC8102-X016 be used interchangeably with MOC8102W?

A: Yes. Both Vishay variants meet the core substitution criteria: 5300Vrms isolation voltage, single-channel transistor output, 50mA output current, 6-DIP package, and -55°C to 100°C operating temperature range. The electrical parameters fall within compatible ranges for direct replacement.

Q: What is the difference between MOC8102-X006 and MOC8102-X016?

A: Both parts are manufactured by Vishay Semiconductor Opto Division and share identical electrical specifications. The designation suffix (-X006 versus -X016) indicates different internal manufacturing or packaging variants, but electrical performance is equivalent.

Q: Is MOC8102G a suitable replacement for MOC8102W?

A: MOC8102G maintains package compatibility and output characteristics but specifies isolation voltage as 7.5Vpk rather than 5300Vrms. Selection depends on circuit isolation requirements. If 5300Vrms isolation is mandatory, MOC8102G is not suitable. If lower isolation voltage is acceptable, MOC8102G is compatible.

Q: What are the key differences in timing characteristics?

A: MOC8102W specifies turn-on/turn-off times of 2µs and 3µs with rise/fall times of 1µs and 2µs. Vishay variants (MOC8102-X006 and MOC8102-X016) specify 3µs and 2.3µs turn-on/turn-off with 2µs and 2µs rise/fall times. These differences are within typical application tolerances for optoisolator circuits.

Q: Are all substitute parts RoHS compliant?

A: MOC8102-X006, MOC8102-X016, and MOC8102G are all ROHS3 compliant. The original MOC8102W RoHS status is not specified in available documentation.

Q: What is the maximum forward current difference between MOC8102W and the Vishay variants?

A: MOC8102W specifies 100mA maximum DC forward current, while MOC8102-X006 and MOC8102-X016 specify 60mA. Circuit designs must account for this reduced input current capability in the Vishay variants.

Q: Are all parts available in the same packaging format?

A: Yes. All substitute parts use 6-DIP (0.400", 10.16mm) through-hole packaging with identical pin pitch and mounting compatibility.
