Key Parameters

Substitute Part Grouping Explanation

The Dialight 5554003F qualifies as a direct substitute based on matching electrical and mechanical parameters across all critical specifications. Substitution is valid when the following parameters are identical:

• Configuration: 4 Wide LED arrangement
• Color: Red (x 4) with 650nm peak wavelength
• Voltage Rating: 5V nominal operation
• Current: 6mA per LED
• Millicandela Rating: 1.9mcd brightness output
• Viewing Angle: 40° optical field
• Lens Type and Size: Clear lens, 2.00mm diameter
• Mounting Type: Through Hole, Right Angle orientation
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The 5554003F maintains full compatibility with circuit designs and PCB layouts specified for the original 5554003 component.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5554003F is the direct active equivalent for the obsolete 5554003. Selection of the 5554003F is appropriate for all applications where the original component was specified, as all functional electrical and mechanical parameters remain unchanged.

The 5554003F offers additional advantages through ROHS3 compliance certification, addressing regulatory requirements for new designs and production environments subject to RoHS directives. The original 5554003 is classified as RoHS non-compliant and should be replaced in applications requiring compliance documentation.

Both components maintain REACH Unaffected status and EAR99 export classification. Moisture sensitivity level remains MSL 1 (Unlimited) for both parts, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5554003F be used as a direct replacement for the 5554003 in existing designs?

A: Yes. The 5554003F maintains identical electrical specifications (5V, 6mA, 1.9mcd, 650nm), optical characteristics (40° viewing angle, clear lens, 2.00mm diameter), and mechanical mounting (through-hole, right-angle). PCB layouts and circuit designs require no modification.

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

A: The 5554003 is obsolete with RoHS non-compliant status. The 5554003F is an active product with ROHS3 compliance certification. All functional parameters are identical.

Q: Are there packaging differences between the 5554003 and 5554003F?

A: The 5554003 packaging designation is not specified. The 5554003F is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the 5554003F require different PCB footprint or mounting considerations?

A: No. Both components use identical through-hole, right-angle mounting. PCB footprints, hole spacing, and mounting procedures remain unchanged.

Q: What compliance certifications apply to the 5554003F?

A: The 5554003F holds ROHS3 compliance certification and maintains REACH Unaffected status. Export classification is EAR99 for both parts.
