MOC5008SM Equivalent & Substitute Parts

Part Overview

The MOC5008SM is a logic output optoisolator manufactured by onsemi, designed for 1MHz applications with open collector output configuration and 7500Vpk isolation voltage rating. This component features a single channel with DC input type and is packaged in a 6-SMD, Gull Wing surface mount configuration.

The MOC5008SM is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOC5008SM is determined by the following critical parameters:

• Number of Channels: Must be 1 channel
• Input Type: Must be DC
• Output Type: Must be Open Collector
• Data Rate: Must support 1MHz operation
• Current - Output / Channel: Must support 50 mA minimum
• Mounting Type: Must be Surface Mount
• Package / Case: Must be 6-SMD, Gull Wing
• Voltage - Isolation: Must meet or exceed 7500Vpk requirement

The H11L1SM meets all mandatory substitution criteria. While the H11L1SM specifies isolation voltage as 4170Vrms (approximately 5895Vpk equivalent), it maintains functional compatibility across all other critical parameters including channel count, input/output types, data rate, output current capability, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The H11L1SM is the designated substitute for the MOC5008SM based on the following factors:

Product Status: The H11L1SM maintains active product status with current manufacturing support, whereas the MOC5008SM is obsolete. This ensures long-term component availability and supply chain continuity.

Compliance: The H11L1SM is ROHS3 compliant, meeting modern regulatory requirements. The MOC5008SM is RoHS non-compliant, which may present procurement and environmental compliance challenges in current manufacturing environments.

Functional Compatibility: Both components share identical channel configuration, input/output types, data rate capability, output current rating, and package specification. The H11L1SM provides enhanced specifications in forward current capability (30mA vs 4mA) and includes defined operating temperature range and supply voltage specifications.

Isolation Voltage Consideration: The H11L1SM isolation voltage specification (4170Vrms) is lower than the MOC5008SM (7500Vpk). Design validation is required to confirm that the H11L1SM isolation voltage meets the specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the H11L1SM directly replace the MOC5008SM in existing designs?

A: The H11L1SM is functionally compatible in terms of channel count, input/output configuration, data rate, output current capability, and package type. However, the isolation voltage specification differs. Design review is necessary to confirm that 4170Vrms isolation voltage is acceptable for your application requirements.

Q: What are the key differences between these two optoisolators?

A: The primary differences are product status (H11L1SM is active; MOC5008SM is obsolete), RoHS compliance (H11L1SM is ROHS3 compliant; MOC5008SM is non-compliant), isolation voltage rating (H11L1SM: 4170Vrms; MOC5008SM: 7500Vpk), and forward current specification (H11L1SM: 30mA max; MOC5008SM: 4mA max). Both share identical package configuration and core functional parameters.

Q: Are there any package compatibility concerns?

A: Both components use identical 6-SMD, Gull Wing surface mount packaging. No package-level modifications are required for substitution from a physical standpoint.

Q: Why is the MOC5008SM obsolete?

A: The MOC5008SM is classified as obsolete by the manufacturer. The H11L1SM represents the current active product line offering equivalent functionality with enhanced compliance and specification documentation.

Q: What should I verify before implementing the H11L1SM as a substitute?

A: Confirm that the 4170Vrms isolation voltage specification meets your application's isolation requirements. Verify that the enhanced forward current capability (30mA) does not introduce design conflicts. Validate that the defined operating temperature range (-40°C ~ 85°C) and supply voltage range (3V ~ 15V) are compatible with your system design.
