MOC81063SD Equivalent & Substitute Parts

Part Overview

The MOC81063SD is an optoisolator with transistor output manufactured by onsemi, featuring 5300Vrms isolation voltage and single-channel configuration in 6-SMD surface mount packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The MOC81063SD serves applications requiring galvanic isolation with DC input and transistor output topology.

Substitute Part Grouping Explanation

Substitution eligibility for the MOC81063SD is determined by the following critical parameters:

Isolation Voltage: Minimum 5300Vrms (equal or greater)
Number of Channels: 1 channel required
Output Type: Transistor output
Package / Case: 6-SMD, Gull Wing surface mount
Current Transfer Ratio: 50% to 150% @ 10mA
Output Voltage Rating: 70V maximum
Output Current: 50mA per channel
Vce Saturation: 400mV maximum
Input Type: DC
Mounting Type: Surface Mount

Substitute parts must maintain compatibility across these parameters. Parts with lower isolation voltage ratings (4170Vrms) are listed for reference but do not meet the full electrical specification of the MOC81063SD.

Engineering Selection Recommendations

Full Electrical Equivalent (5300Vrms Isolation):

MOC8106SMT&R (Isocom Components 2004 LTD) is the only substitute that maintains the 5300Vrms isolation voltage specification of the MOC81063SD. This part is currently active and available. The MOC8106SMT&R exhibits longer turn-on/turn-off times (7.5µs, 5.7µs) and rise/fall times (3.2µs, 4.7µs) compared to the original specification, which must be evaluated against application timing requirements. Operating temperature range matches the MOC81063SD (-55°C ~ 100°C). Packaging is supplied in Tape & Reel format.

Reduced Isolation Voltage Alternatives (4170Vrms):

MOC8106SM (onsemi) and MOC8106SR2VM (Fairchild Semiconductor) both feature 4170Vrms isolation voltage, representing a 21% reduction from the MOC81063SD specification. These parts are suitable only for applications where lower isolation voltage is acceptable. MOC8106SM is supplied in Tube packaging with higher inventory availability (16,280 pcs). MOC8106SR2VM is supplied in Bulk packaging. Both parts have restricted operating temperature ranges (-40°C ~ 100°C) compared to the MOC81063SD.

Compliance and Regulatory Status:

All substitute parts maintain REACH Unaffected and EAR99 ECCN classifications consistent with the original part. MOC8106SM carries RoHS3 Compliance certification.

Frequently Asked Questions (FAQ)

Q: Can MOC8106SM or MOC8106SR2VM be used as direct replacements for MOC81063SD?

A: These parts are not direct electrical equivalents. Both feature 4170Vrms isolation voltage compared to the MOC81063SD's 5300Vrms specification. Selection depends on whether your application requires the full 5300Vrms isolation rating or can operate at 4170Vrms.

Q: What are the timing differences between MOC8106SMT&R and MOC81063SD?

A: MOC8106SMT&R has longer switching times. Turn-on/turn-off times are 7.5µs and 5.7µs (versus 2µs and 3µs), and rise/fall times are 3.2µs and 4.7µs (versus 1µs and 2µs). Applications with strict timing requirements must account for these differences.

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

A: All substitute parts use 6-SMD, Gull Wing surface mount packaging. However, they differ in supplier packaging: MOC8106SMT&R is supplied in Tape & Reel, MOC8106SM in Tube, and MOC8106SR2VM in Bulk. Select based on your procurement and assembly requirements.

Q: What is the operating temperature range difference?

A: MOC81063SD and MOC8106SMT&R both operate from -55°C to 100°C. MOC8106SM and MOC8106SR2VM have a restricted range of -40°C to 100°C. Applications requiring -55°C operation must use MOC8106SMT&R or the original part.

Q: Which substitute part has the best inventory availability?

A: MOC8106SM has the highest inventory with 16,280 pcs in stock. MOC8106SMT&R has 686 pcs, and MOC8106SR2VM has 2,442 pcs available.
