Parameter Comparison

Engineering Selection Recommendations

The 4N24U is the direct substitute for the 4N24UTXV. Both components are manufactured by TT Electronics/Optek Technology and share identical electrical specifications and mechanical packaging.

The 4N24U offers the advantage of active product status, ensuring continued availability and supply chain support. The 4N24U also provides an extended lower operating temperature limit of -65°C compared to the 4N24UTXV at -55°C, offering broader thermal operating range compatibility.

Both parts maintain ROHS3 compliance and MSL 1 rating, supporting equivalent environmental and reliability requirements for surface mount assembly and field deployment.

Frequently Asked Questions (FAQ)

Q: Can the 4N24U directly replace the 4N24UTXV in existing designs?

A: Yes. The 4N24U is electrically and mechanically identical to the 4N24UTXV. Both components feature the same 1000VDC isolation voltage, single-channel transistor output with base terminal, current transfer ratio, output voltage rating, saturation characteristics, and switching speed. The 6-LCC package dimensions and pinout are identical, enabling direct PCB substitution without circuit modification.

Q: What is the primary difference between these two parts?

A: The 4N24UTXV is classified as obsolete, while the 4N24U maintains active product status. The 4N24U also specifies an extended lower operating temperature of -65°C versus -55°C for the 4N24UTXV. All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both the 4N24UTXV and 4N24U are ROHS3 compliant with MSL 1 rating. Both components carry identical REACH and ECCN classifications, supporting equivalent regulatory and export compliance requirements.

Q: Is the 6-LCC package suitable for automated assembly?

A: Yes. The 6-LCC package is a surface mount configuration with no leads, designed for automated pick-and-place assembly and reflow soldering processes. The 6.22x4.32mm package dimensions are standard for high-density PCB layouts.

Q: What isolation voltage does this optoisolator provide?

A: Both the 4N24UTXV and 4N24U provide 1000VDC isolation, suitable for applications requiring high-voltage galvanic separation between input and output circuits.
