MOC5008SVM Equivalent & Substitute Parts

Part Overview

The MOC5008SVM is a logic output optoisolator manufactured by onsemi, designed for 1MHz applications with open collector output and 7500Vpk isolation voltage. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part is housed in a 6-SMD, Gull Wing surface mount package and is RoHS non-compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC5008SVM is determined by the following critical parameters:

• Number of Channels: Must be 1 channel
• Input/Output Configuration: 1 input, 0 side 2 inputs
• Output Type: Open Collector
• Data Rate: 1MHz capability
• Current - Output / Channel: 50 mA
• Mounting Type: Surface Mount
• Package / Case: 6-SMD, Gull Wing

The H11L1SVM meets these core functional requirements. While the H11L1SVM features a lower isolation voltage rating (4170Vrms versus 7500Vpk), it maintains electrical and mechanical compatibility for applications where the reduced isolation voltage is acceptable. The substitute part is active in production status and RoHS3 compliant, offering improved availability and regulatory compliance compared to the obsolete MOC5008SVM.

Parameter Comparison

Engineering Selection Recommendations

The H11L1SVM is the designated substitute for the MOC5008SVM based on functional equivalence in channel configuration, input/output topology, data rate, and package form factor. The substitute part offers the following advantages:

• Active Product Status: H11L1SVM is in active production, ensuring long-term availability and supply chain stability compared to the obsolete MOC5008SVM.
• Regulatory Compliance: H11L1SVM is ROHS3 compliant, meeting current environmental and regulatory requirements, whereas MOC5008SVM is RoHS non-compliant.
• Electrical Compatibility: Both parts maintain identical channel count, output type, data rate, and output current specifications, ensuring functional interchangeability in circuit designs.

Selection of H11L1SVM is appropriate for applications where the isolation voltage requirement does not exceed 4170Vrms. Applications requiring the full 7500Vpk isolation voltage of the MOC5008SVM must evaluate alternative optoisolator families with higher isolation ratings.

Frequently Asked Questions (FAQ)

Q: Can H11L1SVM directly replace MOC5008SVM in existing designs?

A: H11L1SVM is functionally equivalent in terms of channel configuration, output type, data rate, and output current. Direct replacement is possible if the application isolation voltage requirement does not exceed 4170Vrms. Circuit board layout compatibility is maintained due to identical 6-SMD, Gull Wing packaging.

Q: What is the primary difference between MOC5008SVM and H11L1SVM?

A: The primary difference is isolation voltage rating. MOC5008SVM provides 7500Vpk isolation, while H11L1SVM provides 4170Vrms isolation. Additionally, H11L1SVM is an active product with RoHS3 compliance, whereas MOC5008SVM is obsolete and RoHS non-compliant.

Q: Are there packaging differences between these parts?

A: Both parts use identical 6-SMD, Gull Wing surface mount packaging. No PCB layout modifications are required for substitution.

Q: What is the forward current difference between these optoisolators?

A: MOC5008SVM has a maximum DC forward current of 4mA, while H11L1SVM has a maximum DC forward current of 30mA. This difference does not affect substitution compatibility for standard applications.

Q: Is H11L1SVM suitable for high-voltage isolation applications?

A: H11L1SVM is rated for 4170Vrms isolation voltage. Applications requiring isolation voltages exceeding this rating must use alternative optoisolator components with higher isolation specifications.
