Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5553401 is determined by strict equivalence across the following critical parameters:

• Color: Yellow
• Wavelength - Peak: 583nm
• Configuration: Single
• Current Rating: 20mA
• Millicandela Rating: 2mcd
• Viewing Angle: 40°
• Lens Type: Clear
• Lens Style: Round with Domed Top
• Lens Size: 2.00mm Dia
• Voltage Rating: 2.2V
• Mounting Type: Through Hole

The substitute part 5553401F maintains identical electrical and mechanical specifications to the main part, with the primary distinction being active product status and updated RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5553401F serves as the direct active equivalent to the obsolete 5553401. Both components share identical electrical performance characteristics and mechanical form factors, ensuring functional interchangeability in through-hole circuit board applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 5553401 is classified as obsolete and carries RoHS non-compliant status. The 5553401F is an active product with ROHS3 compliance certification, making it the appropriate selection for new designs and applications subject to RoHS regulatory requirements.

For applications where RoHS compliance is not mandated, either part satisfies the electrical and mechanical requirements. For new production or designs requiring regulatory compliance documentation, the 5553401F is the specified equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 5553401F be used as a direct replacement for the 5553401?

A: Yes. The 5553401F maintains identical specifications across all critical electrical and mechanical parameters: 2.2V voltage rating, 20mA current, 2mcd brightness, 583nm wavelength, 40° viewing angle, and 2.00mm through-hole mounting configuration. Both components are single yellow LEDs with clear, domed lenses.

Q: What is the difference between these two part numbers?

A: The 5553401F is the active production equivalent of the obsolete 5553401. The primary differences are product status (active vs. obsolete) and RoHS compliance classification (ROHS3 compliant vs. RoHS non-compliant). Electrical and mechanical specifications are identical.

Q: Are there packaging differences between 5553401 and 5553401F?

A: The 5553401 is supplied in standard packaging, while the 5553401F is supplied in bulk packaging. Both formats contain the same component with identical specifications.

Q: Which part should be selected for new designs?

A: The 5553401F is the appropriate selection for new designs. As an active product with current RoHS3 compliance certification, it ensures ongoing availability and regulatory alignment for production applications.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. The identical electrical ratings (2.2V, 20mA), optical characteristics (583nm, 2mcd, 40° viewing angle), and mechanical form factor (2.00mm through-hole) ensure functional interchangeability in existing circuit board designs.
