Substitute Part Grouping Explanation

Substitution eligibility for the 4N47UTXV is determined by strict equivalence across the following critical parameters:

  • Isolation Voltage: 1000VDC minimum
  • Number of Channels: Single channel (1)
  • Output Configuration: Transistor with Base
  • Current Transfer Ratio: Minimum 50% @ 2mA
  • Maximum Output Voltage: 45V or greater
  • Package Type: 6-LCC surface mount, no lead
  • Operating Temperature Range: -55°C to 125°C minimum
  • Compliance Standards: ROHS3 Compliant, REACH Unaffected

The 4N47U qualifies as a direct substitute based on identical electrical specifications, mechanical compatibility, and regulatory compliance. The primary distinction is product status: 4N47U is active and currently available, whereas 4N47UTXV is obsolete.

Engineering Selection Recommendations

The 4N47U is the direct functional equivalent for the obsolete 4N47UTXV. Both components share identical electrical characteristics, mechanical dimensions, and regulatory compliance certifications. The 4N47U maintains ROHS3 compliance and REACH unaffected status, ensuring compatibility with current manufacturing and environmental standards.

Selection of the 4N47U over the 4N47UTXV is justified by active product status and confirmed inventory availability. The active status ensures access to current manufacturing batches, technical support, and long-term supply chain reliability. No electrical or mechanical redesign is required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the 4N47U be used as a direct replacement for the 4N47UTXV in existing designs?

A: Yes. The 4N47U is electrically and mechanically identical to the 4N47UTXV. All electrical parameters, isolation voltage, output characteristics, and package dimensions are equivalent. No circuit modifications are required.

Q: What is the primary reason for substituting the 4N47UTXV with the 4N47U?

A: The 4N47UTXV is classified as obsolete, while the 4N47U maintains active product status. This substitution ensures access to current inventory, manufacturing support, and supply chain continuity.

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

A: No. Both the 4N47UTXV and 4N47U are ROHS3 compliant and REACH unaffected. Regulatory compliance is identical.

Q: Is the 6-LCC package footprint identical between both parts?

A: Yes. Both components use the 6-LCC (6.22x4.32) surface mount package with no lead configuration. PCB layout and assembly processes remain unchanged.

Q: What are the critical parameters that define substitution eligibility for this optoisolator?

A: Substitution eligibility is determined by: 1000VDC isolation voltage, single-channel configuration, transistor with base output type, minimum 50% current transfer ratio at 2mA, 45V maximum output voltage, 6-LCC package type, -55°C to 125°C operating temperature range, and ROHS3 compliance.
