MOC8050 Equivalent & Substitute Parts

Part Overview

The MOC8050 is a 6-pin optoisolator with Darlington output configuration, designed for high-voltage isolation applications. It provides 5300Vrms isolation voltage with a single channel and Darlington output stage. The main part from Isocom Components 2004 LTD is currently active in production. Substitute parts may be required due to supply chain considerations, packaging preferences, or design flexibility in component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOC8050 are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Isolation voltage of 5300Vrms
• Single channel configuration
• Darlington output stage
• Current transfer ratio minimum of 500% @ 10mA
• Maximum output voltage of 80V
• Output current capability of 150mA per channel
• 6-DIP package form factor (0.300", 7.62mm)
• Through-hole mounting compatibility
• DC input type
• Operating temperature range of -55°C to 100°C

The MOC8050 from onsemi meets all these parametric requirements and qualifies as a direct parametric equivalent, despite differences in product status and packaging format.

Engineering Selection Recommendations

The MOC8050 from onsemi is a parametric equivalent to the Isocom MOC8050. However, the onsemi variant carries an obsolete product status, which may impact long-term availability and supply chain reliability. Selection should prioritize the active Isocom MOC8050 for new designs requiring sustained component availability.

Both variants maintain REACH compliance and equivalent electrical performance across all critical parameters. The onsemi version is supplied in tube packaging, whereas the Isocom packaging format is not specified in the provided data. Verify packaging compatibility with assembly requirements before final component selection.

Frequently Asked Questions (FAQ)

Q: Can the onsemi MOC8050 be used as a direct replacement for the Isocom MOC8050?

A: Yes, from a parametric standpoint. Both parts share identical electrical specifications including isolation voltage, output current, switching times, and operating temperature range. However, the onsemi part is obsolete, which may limit availability for future procurement.

Q: What are the critical parameters that define substitutability for the MOC8050?

A: Substitutability is determined by: 5300Vrms isolation voltage, single-channel Darlington output, 500% minimum current transfer ratio at 10mA, 80V maximum output voltage, 150mA output current per channel, 6-DIP package form factor, and -55°C to 100°C operating temperature range.

Q: Does packaging format affect substitutability?

A: Packaging format (tube, reel, or bulk) does not affect electrical substitutability but impacts handling, storage, and assembly processes. Verify that the supplied packaging format is compatible with your assembly workflow.

Q: Are there compliance differences between the Isocom and onsemi variants?

A: Both parts maintain REACH compliance. The Isocom variant is ROHS3 compliant; compliance status for the onsemi variant is not specified in the provided data. Verify compliance requirements for your application before selection.

Q: Why is the onsemi MOC8050 marked as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions. Obsolete status does not indicate functional deficiency but signals reduced availability and potential supply constraints.
