Substitute Part Grouping Explanation

Substitution of the Dialight 5595701801 is based on strict equivalence across the following critical parameters:

  • Lamp color and wavelength (Yellow, 583nm)
  • Electrical ratings (2.1V forward voltage, 20mA maximum current)
  • Optical characteristics (140mcd brightness, 24° viewing angle)
  • Mechanical form factor (5mm T-1 3/4 lens, round domed top, colorless clear lens)
  • Panel mounting interface (0.25" round cutout)

The substitute part 5595701801F maintains full compatibility across all these parameters while offering improved product status and compliance certification.

Engineering Selection Recommendations

The Dialight 5595701801F is the direct substitute for the obsolete 5595701801. Both components share identical electrical and optical specifications, ensuring functional equivalence in panel-mount LED indicator applications.

The primary distinction is product status and regulatory compliance. The 5595701801F is an active product with ROHS3 compliance certification, whereas the original part is obsolete and RoHS non-compliant. For new designs or system refreshes, the 5595701801F is the appropriate selection. For legacy system maintenance where the original part remains available, either component meets the electrical and mechanical requirements.

Both parts maintain REACH Unaffected status and EAR99 export classification, with identical moisture sensitivity ratings and tariff codes.

Frequently Asked Questions (FAQ)

Q: Can the 5595701801F directly replace the 5595701801 in existing assemblies?

A: Yes. The 5595701801F maintains identical electrical ratings (2.1V, 20mA), optical output (140mcd at 583nm), viewing angle (24°), and mechanical form factor (5mm T-1 3/4 lens, 0.25" round panel cutout). No circuit modifications or panel redesign are required.

Q: What is the difference between these two parts?

A: The 5595701801F is the active production variant with ROHS3 compliance. The 5595701801 is obsolete and RoHS non-compliant. Functionally and mechanically, they are equivalent.

Q: Are there termination differences between these parts?

A: The 5595701801 specifies wire wrap termination. The 5595701801F termination style is not specified in the available data. Verify termination compatibility with your assembly process before procurement.

Q: What packaging is available for the 5595701801F?

A: The 5595701801F is supplied in bulk packaging, whereas the original part packaging is not specified.

Q: Are both parts suitable for RoHS-regulated applications?

A: Only the 5595701801F carries ROHS3 compliance certification. The 5595701801 is RoHS non-compliant and is not suitable for applications subject to RoHS directives.
