MOC81013SD Equivalent & Substitute Parts

Part Overview

The MOC81013SD 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 part operates across a temperature range of -55°C to 100°C with 50mA output current capability and is suitable for DC input applications requiring galvanic isolation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC81013SD is determined by the following critical parameters: isolation voltage rating, number of channels, output type (transistor), maximum output voltage, output current capability, saturation voltage, operating temperature range, and surface mount 6-SMD package compatibility.

The substitute parts are grouped into two categories based on isolation voltage alignment:

Category 1: Matched Isolation Voltage (5300Vrms) Parts maintaining the same 5300Vrms isolation specification as the original MOC81013SD, ensuring equivalent electrical performance in high-voltage isolation applications.

Category 2: Lower Isolation Voltage (4170Vrms) Parts with reduced isolation voltage that may be suitable for applications not requiring the full 5300Vrms rating, subject to circuit design verification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Matched Isolation Voltage)

MOC8101-X017T (Vishay Semiconductor Opto Division) is the preferred substitute, maintaining identical 5300Vrms isolation voltage, 50% minimum current transfer ratio, and -55°C to 100°C operating temperature range. This part is active in production status with ROHS3 compliance and 2300 units in stock inventory.

MOC8101SM and MOC8101SMT&R (Isocom Components 2004 LTD) are alternative substitutes with the same 6-SMD package and electrical output specifications. However, these parts specify isolation voltage as 7.5Vpk rather than Vrms, representing a different measurement standard. Both are active in production with ROHS3 compliance. MOC8101SMT&R is supplied in Tape & Reel packaging, while MOC8101SM is supplied in Tube packaging.

Secondary Substitute (Reduced Isolation Voltage)

CNY17F1SR2VM (onsemi) provides 4170Vrms isolation voltage, which is lower than the MOC81013SD specification. This part maintains 40-80% current transfer ratio range, identical output current and saturation voltage specifications, and is supplied in Tape & Reel packaging. Operating temperature range is -40°C to 100°C, which is narrower at the lower end. This substitute is suitable only for applications where 4170Vrms isolation is sufficient.

All substitute parts maintain single-channel transistor output configuration, 50mA output current, 400mV maximum saturation voltage, and 6-SMD Gull Wing surface mount package compatibility with the original MOC81013SD.

Frequently Asked Questions (FAQ)

Q: Can MOC8101-X017T directly replace MOC81013SD in existing designs?

A: MOC8101-X017T maintains all critical electrical parameters: 5300Vrms isolation voltage, 50-80% current transfer ratio, 30V maximum output voltage, 50mA output current, and 400mV saturation voltage. The 6-SMD Gull Wing package is mechanically compatible. This part is the direct equivalent for applications requiring matched isolation voltage performance.

Q: What is the difference between MOC8101SM and MOC8101SMT&R?

A: Both parts are electrically identical with the same specifications. The primary difference is packaging: MOC8101SM is supplied in Tube packaging, while MOC8101SMT&R is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume handling procedures.

Q: Why does CNY17F1SR2VM have a lower isolation voltage rating?

A: CNY17F1SR2VM is specified at 4170Vrms isolation voltage compared to the MOC81013SD at 5300Vrms. This part is suitable only for applications where the lower isolation voltage meets circuit requirements. The reduced isolation rating may affect performance in high-voltage isolation scenarios.

Q: Are all substitute parts RoHS compliant?

A: MOC8101-X017T, MOC8101SM, MOC8101SMT&R, and CNY17F1SR2VM are all ROHS3 compliant. The original MOC81013SD RoHS status is not specified in available documentation.

Q: What is the operating temperature difference between substitutes?

A: MOC81013SD, MOC8101-X017T, MOC8101SM, and MOC8101SMT&R all operate across -55°C to 100°C. CNY17F1SR2VM operates across -40°C to 100°C, with a narrower lower temperature range. Applications requiring operation below -40°C must use one of the -55°C rated alternatives.

Q: Are the isolation voltage specifications comparable between Vrms and Vpk ratings?

A: Vrms (root mean square) and Vpk (peak voltage) are different measurement standards. MOC8101SM and MOC8101SMT&R specify 7.5Vpk isolation, which is not directly comparable to the Vrms ratings of other parts. Circuit design verification is required when considering these parts as substitutes.
