Substitute Part Grouping Explanation

The 5553008F qualifies as a direct substitute for the 5553008 based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Color: Red (matching)
• Wavelength - Peak: 650nm (matching)
• Configuration: Single (matching)
• Current Rating: 3mA (matching)
• Voltage Rating: 24V (matching)
• Millicandela Rating: 9mcd (matching)
• Viewing Angle: 40° (matching)
• Lens Type: Clear (matching)
• Lens Style: Round with Domed Top (matching)
• Lens Size: 2.00mm Dia (matching)
• Mounting Type: Through Hole (matching)

The 5553008F maintains identical functional and physical characteristics to the original part, with the primary distinction being product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 5553008F is the direct substitute for the obsolete 5553008. Both parts are manufactured by Dialight and share identical electrical and mechanical specifications. The 5553008F offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 5553008F meets ROHS3 compliance requirements, whereas the original 5553008 is RoHS non-compliant. For new designs and ongoing production requiring this LED indicator specification, the 5553008F is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 5553008F be used as a direct replacement for the 5553008?

A: Yes. The 5553008F is electrically and mechanically identical to the 5553008, with matching voltage rating (24V), current consumption (3mA), color (red), wavelength (650nm), brightness (9mcd), viewing angle (40°), lens configuration (clear, round with domed top, 2.00mm diameter), and through-hole mounting type.

Q: What is the primary difference between these parts?

A: The 5553008 is obsolete, while the 5553008F maintains active product status. The 5553008F also provides ROHS3 compliance, whereas the original part is RoHS non-compliant.

Q: Are there packaging differences between the 5553008 and 5553008F?

A: Both parts are supplied in bulk packaging. Packaging configuration does not affect functional or mechanical compatibility.

Q: What parameters determine substitution eligibility for this LED indicator?

A: Substitution is determined by matching color, wavelength, configuration, current rating, voltage rating, brightness (millicandela), viewing angle, lens type, lens style, lens diameter, and mounting type. All these parameters are identical between the 5553008 and 5553008F.

Q: Is the 5553008F suitable for applications originally designed for the 5553008?

A: Yes. The 5553008F maintains full compatibility with applications designed for the 5553008, with no modifications to circuit design, PCB layout, or component placement required.
