LED Circuit Board Indicator 5510309010F Equivalent & Substitute Parts
Part Overview
The Dialight 5510309010F is an active, ROHS3-compliant LED circuit board indicator designed for through-hole, right-angle mounting applications. This single yellow diffused LED operates at 2.1V with a 20mA current rating and delivers 6.3mcd brightness output. The component features a 3.00mm diameter round domed lens with a 45° viewing angle, making it suitable for standard PCB indicator applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that meet equivalent electrical and mechanical specifications.

Engineering Selection Recommendations
Both the Dialight 5510309010F and Bivar Inc. H100CYDL are active products with ROHS3 compliance and MSL 1 ratings, confirming suitability for standard PCB assembly environments without moisture sensitivity constraints.
The H100CYDL substitute is appropriate for applications where the lower brightness output (4mcd vs. 6.3mcd) and reduced forward voltage (1.9V vs. 2.1V) do not compromise functional requirements. The lower voltage rating may reduce power consumption in current-limited circuits. Both components share identical mechanical form factors, viewing angles, and mounting configurations, ensuring direct PCB layout compatibility.
Selection between these parts should be based on application-specific brightness requirements and circuit voltage specifications. The main part (5510309010F) is preferred where maximum brightness output is required; the substitute (H100CYDL) is suitable for general indicator applications with standard visibility requirements.
Frequently Asked Questions (FAQ)
Q: Can the H100CYDL directly replace the 5510309010F in all applications?
A: Direct replacement is possible in applications where the lower brightness output (4mcd vs. 6.3mcd) and reduced forward voltage (1.9V vs. 1.9V) are acceptable. PCB layout compatibility is confirmed due to identical mounting type, lens size, and form factor. Circuit voltage and brightness requirements must be evaluated for each specific application.
Q: What are the key differences between these two parts?
A: The primary differences are brightness output (6.3mcd vs. 4mcd), forward voltage (2.1V vs. 1.9V), and current rating specification (20mA specified vs. not specified). Both parts share identical color, wavelength, viewing angle, lens style, and mounting configuration.
Q: Are both parts suitable for high-reliability applications?
A: Both parts are ROHS3 compliant and carry MSL 1 ratings, confirming compliance with standard environmental and regulatory requirements. Product status is active for both manufacturers, ensuring ongoing availability and support.
Q: What packaging differences exist between these parts?
A: The 5510309010F is supplied in bulk packaging, while the H100CYDL is supplied in tray packaging. This difference affects handling and storage procedures but does not impact component functionality or performance.
Q: How do the lens specifications compare?
A: Both parts feature diffused yellow lenses with round domed tops and 45° viewing angles. Lens size is equivalent (3.00mm Dia vs. 3mm, T-1). Optical performance and light distribution characteristics are functionally equivalent.
