MOC8050G Equivalent & Substitute Parts

Part Overview

The MOC8050G is an optoisolator with Darlington output manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5000Vrms in a single-channel configuration with 6-DIP through-hole packaging. The MOC8050G maintains active product status with 733 units in current inventory. Substitute parts are identified when design requirements demand alternative sourcing, inventory constraints arise, or supply chain optimization is necessary while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC8050G are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Voltage isolation rating: 5000Vrms
• Current transfer ratio minimum: 500% @ 10mA
• Output type: Darlington configuration
• Maximum output voltage: 80V
• Maximum output current per channel: 80mA
• Maximum Vce saturation: 1V
• Rise and fall time specifications: 60µs and 53µs
• Package type: 6-DIP through-hole
• Operating temperature range: -55°C ~ 110°C
• Compliance certifications: ROHS3, REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MOC8050XG is a direct parametric equivalent to the MOC8050G. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is determined by availability and supply chain requirements rather than technical performance differences.

Both parts maintain active product status and comply with ROHS3 and REACH requirements, confirming suitability for current design implementations. The MOC8050XG currently maintains higher inventory levels (932 units versus 733 units), which may influence procurement decisions during supply constraints.

Frequently Asked Questions (FAQ)

Q: Can MOC8050XG replace MOC8050G in existing designs? A: Yes. The MOC8050XG is a parametric equivalent with identical electrical and mechanical specifications. No circuit modifications or PCB redesign are required for substitution.

Q: Are there differences in isolation voltage between these parts? A: No. Both the MOC8050G and MOC8050XG provide 5000Vrms isolation rating.
