MOC8106SD Equivalent & Substitute Parts

Part Overview

The MOC8106SD is an optoisolator with transistor output manufactured by onsemi, rated for 5300Vrms isolation voltage in a 6-SMD surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The MOC8106SD series provides galvanic isolation for low-speed switching applications with a single isolated channel and 50mA output current capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOC8106SD is determined by the following critical parameters:

Primary Compatibility Criteria:

• Single channel transistor output optoisolator configuration
• 6-SMD surface mount package with gull wing leads
• Isolation voltage rating (minimum 5300Vrms for direct substitution)
• Current transfer ratio range: 50% to 150% @ 10mA
• Maximum output voltage: 70V
• Output current capability: 50mA
• Vce saturation: 400mV maximum
• Input type: DC

Substitute Classification:

Group A - Direct Substitutes (5300Vrms Isolation):

• MOC8106SMT&R (Isocom Components 2004 LTD): Maintains 5300Vrms isolation rating with identical electrical specifications and package configuration.

Group B - Functional Equivalents (4170Vrms Isolation):

• MOC8106SR2M (onsemi): Reduced isolation voltage (4170Vrms) with active product status and RoHS3 compliance.
• MOC8106SM (onsemi): Reduced isolation voltage (4170Vrms) with active product status, RoHS3 compliance, and largest available inventory.

Group B substitutes are suitable for applications where 4170Vrms isolation meets system requirements, offering the advantage of active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (5300Vrms Isolation Requirement): Select MOC8106SMT&R when the application requires the full 5300Vrms isolation rating of the original MOC8106SD. This substitute maintains identical isolation voltage and operating temperature range (-55°C ~ 100°C). The part is manufactured by Isocom Components 2004 LTD with active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

For Reduced Isolation Voltage Applications (4170Vrms Acceptable): MOC8106SR2M and MOC8106SM are suitable when system isolation requirements are satisfied by 4170Vrms. Both are onsemi products with active status and ROHS3 compliance. MOC8106SM offers the largest inventory (16,280 pcs) and is supplied in tube packaging for standard component handling. MOC8106SR2M is supplied in tape and reel format for automated assembly processes.

Temperature Range Consideration: Applications requiring the full -55°C to 100°C operating range must use MOC8106SD or MOC8106SMT&R. MOC8106SR2M and MOC8106SM operate from -40°C to 100°C, which is acceptable for most commercial and industrial applications but excludes extended low-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can MOC8106SR2M or MOC8106SM be used as direct replacements for MOC8106SD?

A: MOC8106SR2M and MOC8106SM are functional equivalents with reduced isolation voltage (4170Vrms versus 5300Vrms). They are suitable substitutes only if the application isolation voltage requirement is 4170Vrms or lower. All other electrical parameters, package configuration, and pin assignments are compatible.

Q: What is the difference between MOC8106SMT&R and MOC8106SM?

A: Both parts are manufactured by onsemi with identical electrical specifications and 4170Vrms isolation voltage. The primary difference is packaging: MOC8106SMT&R is supplied in tape and reel format for automated pick-and-place assembly, while MOC8106SM is supplied in tube packaging for manual handling and lower-volume applications.

Q: Does the MOC8106SMT&R maintain the same operating temperature range as the MOC8106SD?

A: Yes. MOC8106SMT&R operates from -55°C to 100°C, matching the MOC8106SD specification. MOC8106SR2M and MOC8106SM operate from -40°C to 100°C, which excludes extended low-temperature operation below -40°C.

Q: Are all substitute parts RoHS3 compliant?

A: MOC8106SMT&R, MOC8106SR2M, and MOC8106SM are all ROHS3 compliant. The original MOC8106SD does not specify RoHS status. All substitutes meet current environmental and regulatory requirements.

Q: What is the inventory status for each substitute part?

A: MOC8106SMT&R has 686 pcs in stock, MOC8106SR2M has 2,162 pcs, and MOC8106SM has 16,280 pcs available. All are classified as new original stock.
