Substitute Part Grouping Explanation

Substitution of the MOC211R2M is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating of 2500Vrms
• Single-channel configuration
• Transistor output with base connection
• Current transfer ratio minimum of 20% @ 10mA
• Maximum output voltage of 30V
• Maximum output current of 150mA per channel
• Switching time specifications: 7.5µs turn-on, 5.7µs turn-off
• Rise and fall time characteristics: 3.2µs and 4.7µs respectively
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Operating temperature range of -40°C to 100°C

The MOC211R2VM from Fairchild Semiconductor meets all specified electrical and mechanical parameters and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the MOC211R2M and MOC211R2VM are active production components suitable for direct substitution in applications requiring 2500Vrms optoisolator transistors with base output in 8-SOIC packaging.

The MOC211R2M (onsemi) carries ROHS3 compliance certification and is classified as REACH Unaffected. The MOC211R2VM (Fairchild Semiconductor) is REACH Unaffected with RoHS status listed as not applicable. Both components maintain identical electrical specifications and mechanical compatibility, enabling interchangeable use in circuit designs where the specified parameters are required.

Inventory availability should be considered in component selection: MOC211R2M has 16400 units in stock, while MOC211R2VM has 3338 units available.

Frequently Asked Questions (FAQ)

Q: Can MOC211R2VM replace MOC211R2M in existing designs?

A: Yes. The MOC211R2VM meets all electrical and mechanical specifications of the MOC211R2M, including isolation voltage, output current rating, switching times, and 8-SOIC package dimensions. Direct substitution is electrically and mechanically compatible.

Q: Are there differences in compliance or certification between these parts?

A: The MOC211R2M carries ROHS3 compliance. The MOC211R2VM lists RoHS status as not applicable. Both are REACH Unaffected. Compliance requirements for your specific application should be verified against your design standards.

Q: What determines if a part qualifies as an equivalent?

A: Equivalence is established when all critical parameters match: isolation voltage rating, channel count, output type, current transfer ratio, maximum output voltage and current, switching characteristics, operating temperature range, and package specifications. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Does packaging format affect substitution eligibility?

A: Yes. Both the main part and substitute must use identical package types and dimensions. The MOC211R2M is supplied in Tape & Reel format, while MOC211R2VM is supplied in Bulk format. This affects handling and storage but does not impact electrical compatibility or circuit performance.

Q: Are there other MOC211 variants that could serve as substitutes?

A: Substitution is limited to parts meeting all specified parameters. Only the MOC211R2VM qualifies as a parametric equivalent based on the provided data. Other MOC211 variants with different isolation ratings, channel configurations, or package types are not equivalent.
