MOC216R1M Equivalent & Substitute Parts

Part Overview

The MOC216R1M is an optoisolator transistor with base output manufactured by onsemi, rated for 2500Vrms isolation voltage in an 8-SOIC surface mount package. This component provides galvanic isolation for single-channel DC input applications with transistor output capability. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the MOC216R1M is categorized into two groups based on electrical and mechanical compatibility:

Direct Manufacturer Equivalents maintain identical electrical specifications and package form factor, differing only in manufacturer or packaging format. These parts are fully interchangeable at the circuit level.

Parametric Equivalents share the same isolation voltage (2500Vrms), output type (transistor with base), package (8-SOIC), and critical performance parameters (current transfer ratio, output voltage/current ratings, operating temperature). These parts are functionally equivalent for applications requiring 2500Vrms isolation.

Similar Parts offer higher isolation voltage (4000Vrms) with compatible package and output type but differ in current transfer ratio and switching characteristics. These are suitable for applications where enhanced isolation margin is acceptable.

Key parameters determining substitution eligibility:

Isolation voltage rating (2500Vrms minimum for direct equivalents)
Output type (transistor with base required)
Package form factor (8-SOIC)
Current transfer ratio (50% @ 1mA for direct equivalents)
Maximum output voltage and current ratings

Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Mitigation): MOC216M and MOC216R2M are the primary alternatives. Both maintain active product status with identical electrical specifications to the MOC216R1M. MOC216R2M carries ROHS3 compliance certification, making it suitable for applications with regulatory requirements. MOC216R2VM provides equivalent functionality with Fairchild Semiconductor sourcing.

For Enhanced Isolation Margin: IL215AT and IL216AT offer 4000Vrms isolation rating, providing additional safety margin in high-voltage isolation applications. IL216AT matches the 50% current transfer ratio of the MOC216R1M, while IL215AT provides 20% CTR. Both are ROHS3 compliant and support extended temperature operation to -55°C.

Compliance Considerations: All active substitute parts listed carry ROHS3 compliance and REACH unaffected status, suitable for applications with environmental and regulatory requirements. Moisture sensitivity level remains consistent at MSL 1 (unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can MOC216M directly replace MOC216R1M in existing designs? A: Yes. MOC216M shares identical electrical specifications and 8-SOIC package form factor. The primary difference is manufacturer (Fairchild Semiconductor vs. onsemi) and product status (active vs. obsolete). No circuit modifications are required.

Q: What is the difference between MOC216R2M and MOC216R1M? A: Both parts are manufactured by onsemi with identical electrical performance. MOC216R2M is the active production variant with Tape & Reel packaging, while MOC216R1M is obsolete. MOC216R2M includes ROHS3 compliance certification.

Q: Are IL215AT and IL216AT suitable replacements? A: IL215AT and IL216AT are functionally compatible alternatives with higher isolation voltage (4000Vrms vs. 2500Vrms). IL216AT maintains the 50% current transfer ratio. These parts are suitable when enhanced isolation capability is acceptable. Extended temperature range (-55°C to 100°C) provides additional operational margin.

Q: What packaging options are available? A: All substitute parts use 8-SOIC surface mount package (0.154", 3.90mm width). Packaging formats vary: MOC216M and MOC216R2VM are available in Bulk; MOC216R2M in Tape & Reel; IL215AT in Tape & Reel; IL216AT in Cut Tape & Digi-Reel. Select based on procurement and assembly requirements.

Q: Are there compliance differences between substitutes? A: MOC216R2M and all Vishay IL-series parts carry ROHS3 compliance. All listed parts are REACH unaffected. For applications requiring specific regulatory certifications, verify compliance documentation with the selected manufacturer.

Q: What is the current transfer ratio and why does it matter? A: Current transfer ratio (CTR) defines the ratio of output collector current to input LED current. MOC216R1M, MOC216M, MOC216R2M, MOC216R2VM, and IL216AT all specify 50% minimum CTR @ 1mA. IL215AT specifies 20% CTR. Higher CTR provides better signal transfer efficiency and reduced input current requirements.
