MOC81023SDL Equivalent & Substitute Parts

Part Overview

The MOC81023SDL is a 6-SMD surface mount optoisolator with transistor output manufactured by onsemi. It provides 5300Vrms isolation voltage and is designed for single-channel DC input applications with 50mA output current capability. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOC81023SDL is determined by the following critical parameters:

• Isolation Voltage: 5300Vrms minimum
• Output Type: Transistor output
• Number of Channels: 1 channel
• Current - Output / Channel: 50mA
• Voltage - Output (Max): 30V minimum
• Vce Saturation (Max): 400mV maximum
• Package / Case: 6-SMD, Gull Wing
• Mounting Type: Surface Mount
• Operating Temperature Range: Must encompass -55°C to 100°C

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents: Parts meeting all critical electrical parameters with 5300Vrms isolation voltage and identical output specifications.

Category B - Functional Alternatives: Parts with reduced isolation voltage (4170Vrms) but maintaining all output electrical characteristics and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

MOC8102-X009 and MOC8102-X017 are the primary substitutes for MOC81023SDL. Both are manufactured by Vishay Semiconductor Opto Division and maintain identical electrical specifications including 5300Vrms isolation voltage, 73-117% current transfer ratio, and -55°C to 100°C operating temperature range. Both parts are active products with ROHS3 compliance and are available in tube packaging.

MOC8102SM and MOC8102SMT&R are manufactured by Isocom Components 2004 LTD and share the same base product number (MOC8102). These parts maintain all output electrical characteristics and package compatibility. However, isolation voltage specification is listed as 7.5Vpk, which differs from the 5300Vrms rating of the original part. MOC8102SMT&R is supplied in Tape & Reel format, while MOC8102SM is supplied in tube packaging.

CNY17F2SR2VM is an onsemi product offering reduced isolation voltage at 4170Vrms but maintains all critical output parameters. This part is active and available in Tape & Reel packaging. The operating temperature range is -40°C to 100°C, which does not extend to the lower -55°C specification of the original part. Maximum output voltage is rated at 70V, exceeding the 30V specification of MOC81023SDL.

For applications requiring strict adherence to 5300Vrms isolation voltage and -55°C lower temperature limit, MOC8102-X009 or MOC8102-X017 are the recommended selections. For applications with relaxed isolation voltage requirements, CNY17F2SR2VM provides an active alternative with higher output voltage capability.

Frequently Asked Questions (FAQ)

Q: Can MOC8102-X009 and MOC8102-X017 be used interchangeably with MOC81023SDL?

A: Yes. Both parts maintain identical isolation voltage (5300Vrms), current transfer ratio (73-117% @ 10mA), output voltage (30V max), output current (50mA), and operating temperature range (-55°C to 100°C). Package and pinout are identical 6-SMD, Gull Wing configuration.

Q: What is the difference between MOC8102-X009 and MOC8102-X017?

A: Both parts are manufactured by Vishay Semiconductor Opto Division with identical electrical specifications and package configuration. The primary difference is packaging format: MOC8102-X009 is supplied in tube, while MOC8102-X017 is also supplied in tube. Inventory levels differ between the two variants.

Q: Is CNY17F2SR2VM a direct replacement for MOC81023SDL?

A: CNY17F2SR2VM is a functional alternative, not a direct replacement. It provides reduced isolation voltage (4170Vrms versus 5300Vrms) and does not meet the -55°C lower operating temperature specification. Use only in applications where these parameter reductions are acceptable.

Q: What are the packaging differences among substitute parts?

A: MOC8102-X009 and MOC8102-X017 are supplied in tube packaging. MOC8102SM is supplied in tube. MOC8102SMT&R and CNY17F2SR2VM are supplied in Tape & Reel (TR) format. All maintain identical 6-SMD, Gull Wing package configuration.

Q: Are all substitute parts RoHS compliant?

A: MOC8102-X009, MOC8102-X017, MOC8102SM, and MOC8102SMT&R are ROHS3 compliant. RoHS status for CNY17F2SR2VM is not specified in available documentation.

Q: What is the significance of the isolation voltage specification?

A: Isolation voltage determines the maximum voltage differential that can be safely applied across the optoisolator's isolation barrier. MOC81023SDL and its direct equivalents (MOC8102-X009, MOC8102-X017) are rated for 5300Vrms. CNY17F2SR2VM is rated for 4170Vrms. Applications requiring higher isolation voltage must use parts rated for 5300Vrms or greater.
