MOC81013S Equivalent & Substitute Parts

Part Overview

The MOC81013S is a 6-SMD optoisolator with transistor output manufactured by onsemi, featuring 5300Vrms isolation voltage and 1 channel configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 100°C with a maximum output current of 50mA per channel and is suitable for applications requiring high-voltage isolation in surface mount configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the MOC81013S is determined by the following critical parameters: single-channel configuration, transistor output type, 6-SMD surface mount package with gull wing leads, maximum output voltage of 30V, maximum output current of 50mA per channel, operating temperature range of -55°C to 100°C, and isolation voltage capability. The MOC8101-X017T maintains full electrical and mechanical compatibility with identical isolation voltage (5300Vrms), matching current transfer ratios, and equivalent timing characteristics. The MOC8101SM and MOC8101SMT&R variants differ in isolation voltage specification (7.5Vpk versus 5300Vrms) and lack documented current transfer ratio parameters, representing partial compatibility for applications where lower isolation voltage is acceptable.

Engineering Selection Recommendations

The MOC8101-X017T from Vishay Semiconductor Opto Division is the primary substitute for the obsolete MOC81013S. This part maintains identical isolation voltage (5300Vrms), current transfer ratio specifications (50% to 80% @ 10mA), and all mechanical parameters. The MOC8101-X017T is active in production status and ROHS3 compliant, providing long-term availability and regulatory compliance. Packaging is available in Tape & Reel format, suitable for automated assembly processes.

The MOC8101SM and MOC8101SMT&R from Isocom Components 2004 LTD are secondary alternatives for applications where isolation voltage requirements are less stringent. These parts specify 7.5Vpk isolation voltage, which is substantially lower than the 5300Vrms of the primary part. Current transfer ratio parameters are not documented for these variants. Both are ROHS3 compliant and active in production. MOC8101SM is supplied in tube packaging, while MOC8101SMT&R is available in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can MOC8101-X017T directly replace MOC81013S in all applications? A: Yes, for applications requiring 5300Vrms isolation voltage. The MOC8101-X017T maintains identical electrical specifications including current transfer ratio (50% to 80% @ 10mA), output voltage (30V maximum), output current (50mA), and saturation voltage (400mV). Both parts use the same 6-SMD gull wing package and operate across -55°C to 100°C.

Q: What is the key difference between MOC8101-X017T and MOC8101SM/MOC8101SMT&R? A: The primary difference is isolation voltage. MOC8101-X017T specifies 5300Vrms isolation, matching the original MOC81013S. MOC8101SM and MOC8101SMT&R specify 7.5Vpk isolation, which is significantly lower. Additionally, current transfer ratio parameters are not documented for the MOC8101SM variants.

Q: Are there packaging differences between the substitute parts? A: MOC8101-X017T is supplied in Tape & Reel (TR) format. MOC8101SM is supplied in tube packaging, while MOC8101SMT&R is supplied in Tape & Reel format. All three maintain the same 6-SMD gull wing package configuration.

Q: Do all substitute parts meet RoHS compliance? A: Yes. MOC8101-X017T, MOC8101SM, and MOC8101SMT&R are all ROHS3 compliant. The original MOC81013S RoHS status is not specified.

Q: Which substitute part offers the best long-term availability? A: MOC8101-X017T is recommended for long-term availability. It is active in production status with documented current transfer ratio specifications and ROHS3 compliance. MOC8101SM and MOC8101SMT&R are also active but lack current transfer ratio documentation.
