MOC5009M Equivalent & Substitute Parts

Part Overview

The MOC5009M is a logic output optoisolator manufactured by onsemi, featuring Schmitt trigger output with 1MHz data rate capability and 7500Vpk isolation voltage rating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The part operates as a single-channel optocoupler with open collector output configuration, designed for DC input applications requiring galvanic isolation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC5009M is determined by the following critical parameters:

• Package Compatibility: Both parts must use 6-DIP (0.300", 7.62mm) through-hole mounting to ensure direct PCB compatibility
• Channel Configuration: Single-channel requirement maintained across all substitutes
• Output Architecture: Open collector output type required for functional equivalence
• Input Specification: DC input type required
• Data Rate: 1MHz minimum performance maintained
• Output Current: 50 mA per channel capability required
• Isolation Voltage: Substitute must meet or exceed isolation voltage requirements

The H11L2M qualifies as a direct substitute based on matching package, channel count, output type, input type, data rate, and output current specifications. While the H11L2M features lower isolation voltage (4170Vrms versus 7500Vpk), it maintains all functional electrical parameters required for component substitution in applications where the lower isolation rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The H11L2M serves as the primary substitute for the obsolete MOC5009M. Selection of this substitute is supported by the following factors:

Product Status: The MOC5009M is classified as obsolete, while the H11L2M maintains active product status with current manufacturing availability (15390 Pcs in stock versus 3600 Pcs for the obsolete part).

Regulatory Compliance: The H11L2M achieves ROHS3 compliance, whereas the MOC5009M is RoHS non-compliant. This distinction is significant for applications subject to regulatory requirements or procurement policies mandating RoHS compliance.

Functional Equivalence: Both parts maintain identical package form factor, channel configuration, output type, input type, data rate, and output current specifications. The H11L2M provides additional documented electrical parameters including propagation delay, rise/fall time, forward voltage, supply voltage range, and operating temperature specifications.

Isolation Voltage Consideration: The H11L2M features 4170Vrms isolation voltage compared to the MOC5009M's 7500Vpk isolation rating. Applications requiring the higher isolation voltage of the original part may necessitate alternative substitute evaluation or circuit redesign to accommodate the lower isolation specification.

Frequently Asked Questions (FAQ)

Q: Can the H11L2M directly replace the MOC5009M in existing PCB designs?

A: Yes, the H11L2M provides direct pin-compatible replacement in 6-DIP through-hole applications. Both parts share identical package dimensions, pin count, and functional output characteristics. No PCB layout modifications are required for physical substitution.

Q: What is the primary difference between these two parts?

A: The primary difference is isolation voltage rating. The MOC5009M specifies 7500Vpk isolation, while the H11L2M specifies 4170Vrms isolation. Applications requiring the higher isolation voltage of the original part must evaluate whether the lower rating of the substitute is acceptable for the intended circuit function.

Q: Why is the MOC5009M classified as obsolete?

A: The MOC5009M is listed as obsolete by the manufacturer. The H11L2M represents the active product line continuation, offering improved compliance characteristics and documented electrical specifications.

Q: Are there any compliance differences between these parts?

A: Yes. The MOC5009M is RoHS non-compliant, while the H11L2M achieves ROHS3 compliance. For applications subject to RoHS requirements, the H11L2M is the appropriate selection.

Q: What are the input current requirements for each part?

A: The MOC5009M specifies maximum DC forward current of 10mA. The H11L2M specifies maximum DC forward current of 30mA. The H11L2M's higher input current capability provides greater design flexibility for input circuit configurations.

Q: Are timing specifications available for both parts?

A: The MOC5009M does not provide documented propagation delay or rise/fall time specifications. The H11L2M specifies 4µs maximum propagation delay (both directions) and 100ns typical rise/fall time, enabling precise timing analysis for the substitute part.
