MOC5008M Equivalent & Substitute Parts

Part Overview

The MOC5008M is a logic output optoisolator manufactured by onsemi, featuring 1MHz data rate capability with open collector output configuration in a 6-DIP package. This component provides 7500Vpk isolation voltage for single-channel DC input applications. The MOC5008M is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOC5008M is determined by the following critical parameters that must remain consistent:

• Package compatibility: 6-DIP (0.300", 7.62mm) form factor for direct board-level replacement
• Channel configuration: Single-channel optoisolator with 1 input and 0 side 2 inputs
• Output architecture: Open collector output topology
• Data rate: 1MHz operational capability
• Output current capacity: 50 mA per channel minimum
• Input signal type: DC input
• Isolation voltage: Minimum isolation rating must meet or exceed application requirements

The H11L1M qualifies as a direct substitute based on matching all critical parameters: identical 6-DIP package, single-channel configuration, open collector output, 1MHz data rate, 50 mA output current, and DC input type. While the H11L1M specifies 4170Vrms isolation (lower than MOC5008M's 7500Vpk), this represents a conservative substitution for applications not requiring the maximum isolation voltage of the obsolete part.

Engineering Selection Recommendations

The H11L1M is the designated substitute for MOC5008M applications. Selection is based on the following engineering criteria:

Product Status: The MOC5008M is obsolete with no ongoing manufacturing support. The H11L1M maintains active product status with current manufacturing and full availability.

Compliance and Certifications: The H11L1M achieves ROHS3 compliance, addressing regulatory requirements for new designs and procurement cycles. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Functional Equivalence: The H11L1M provides identical channel count, input/output architecture, data rate, and output current specifications. The higher forward current capability (30mA vs. 4mA) of the H11L1M represents an enhancement for input-side design flexibility.

Isolation Voltage Consideration: Applications requiring the full 7500Vpk isolation of the MOC5008M must evaluate whether the H11L1M's 4170Vrms isolation rating satisfies system-level isolation requirements. For standard industrial and consumer applications operating within 4170Vrms isolation specifications, the H11L1M provides direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can H11L1M directly replace MOC5008M in existing PCB designs?

A: Yes. Both components use identical 6-DIP (0.300", 7.62mm) package geometry and pinout configuration, enabling direct board-level substitution without layout modifications.

Q: What is the primary difference between MOC5008M and H11L1M?

A: The MOC5008M is obsolete; the H11L1M is an active product. Both share identical channel configuration, output type, data rate, and output current specifications. The H11L1M provides enhanced input current capability (30mA vs. 4mA) and specifies operating temperature range (-40°C to 85°C) and supply voltage range (3V to 15V).

Q: Does the lower isolation voltage of H11L1M affect compatibility?

A: The H11L1M specifies 4170Vrms isolation versus MOC5008M's 7500Vpk. Applications requiring maximum isolation voltage must confirm that 4170Vrms meets system isolation requirements. For standard applications, this isolation rating is sufficient.

Q: Are there packaging differences between these parts?

A: No. Both components are supplied in 6-DIP through-hole packages with identical mechanical dimensions (0.300", 7.62mm). The H11L1M is available in tube packaging.

Q: What compliance advantages does H11L1M offer?

A: The H11L1M is ROHS3 compliant, meeting current regulatory requirements for new product designs and procurement. The MOC5008M is RoHS non-compliant, limiting its use in regulated applications.
