Key Parameters

Substitute Part Grouping Explanation

The Dialight 5552008F qualifies as a direct substitute based on the following critical parameters:

• Color and Wavelength: Both parts emit red light at 650nm peak wavelength
• Configuration: Single LED configuration in both parts
• Current Rating: Identical 3mA current consumption
• Voltage Rating: Both rated for 24V operation
• Mechanical Form Factor: Identical 2.00mm diameter round lens with domed top
• Mounting Interface: Both use through-hole, right-angle mounting
• Viewing Angle: Both provide 40° viewing angle
• Series Compatibility: Both belong to the Dialight 555 series

The primary distinction is product status: the 5552008 is obsolete while the 5552008F is active, with improved RoHS3 compliance and higher current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5552008F is the designated active equivalent for the obsolete 5552008. Selection of the 5552008F is supported by:

• Product Status: The 5552008F maintains active production status, ensuring long-term supply chain viability and component availability
• Regulatory Compliance: The 5552008F achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and manufacturing
• Functional Equivalence: Identical electrical and mechanical specifications across all critical parameters ensure direct form-fit-function compatibility
• Series Continuity: Both components belong to the Dialight 555 series, maintaining design consistency

The 5552008F is suitable for direct replacement in new production, field service, and retrofit applications where the 5552008 was previously specified.

Frequently Asked Questions (FAQ)

Q: Can the 5552008F be used as a direct replacement for the 5552008?

A: Yes. The 5552008F provides identical electrical performance (24V, 3mA, 650nm red) and mechanical form factor (2.00mm round domed lens, through-hole right-angle mount). Both components are functionally interchangeable in circuit board applications.

Q: What is the difference in brightness between these parts?

A: The 5552008 is rated at 9mcd while the 5552008F is rated at 0.9mcd. This represents a difference in luminous intensity. Verify that the reduced brightness of the 5552008F meets application visibility requirements before substitution.

Q: Why should I use the 5552008F instead of the 5552008?

A: The 5552008 is obsolete and subject to supply discontinuation. The 5552008F is an active product with higher inventory availability and ROHS3 compliance, making it the appropriate choice for new designs and ongoing production.

Q: Are there packaging differences between these parts?

A: The 5552008 packaging is unspecified in available data. The 5552008F is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same regulatory standards?

A: The 5552008 is RoHS non-compliant. The 5552008F is ROHS3 compliant. Both are REACH unaffected and classified under ECCN EAR99. For applications requiring RoHS compliance, the 5552008F is the required selection.
