LED Circuit Board Indicator 5510801F Equivalent & Substitute Parts

Part Overview

The Dialight 5510801F is an LED Circuit Board Indicator (CBI) designed for through-hole, right-angle mounting applications. This single blue LED operates at 4.6V with a 20mA current rating and delivers 12mcd luminous intensity. The component features a 3mm T-1 form factor with a round domed lens and maintains a 70° viewing angle. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative inventory sources when the primary part becomes unavailable.

Substitute Part Grouping Explanation

The Dialight 5510803F qualifies as a direct substitute for the 5510801F based on the following matching electrical and mechanical parameters:

Matching criteria: Manufacturer (Dialight), Series (551), Color (Blue), Wavelength - Peak (428nm), Configuration (Single), Voltage Rating (4.6V), Current (20mA), Viewing Angle (70°), Lens Size (3mm, T-1), Lens Style (Round with Domed Top), Mounting Type (Through Hole, Right Angle), RoHS Status (ROHS3 Compliant), and MSL Rating (1 - Unlimited).

The substitute part maintains identical electrical performance specifications and physical form factor, ensuring direct compatibility in circuit board applications without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both the 5510801F and 5510803F are active production parts with full RoHS3 compliance and REACH unaffected status. The 5510803F offers a marginal luminous intensity increase of 0.5mcd (12.5mcd versus 12mcd), which remains within the operational envelope of applications designed for the 5510801F. Selection between these parts should be based on inventory availability and supply chain requirements, as both parts satisfy identical electrical and mechanical interface requirements. The substitute part maintains full compliance with all regulatory certifications applicable to the main part.

Frequently Asked Questions (FAQ)

Q: Can the 5510803F directly replace the 5510801F in existing designs? A: Yes. Both parts share identical voltage ratings (4.6V), current specifications (20mA), form factors (3mm T-1), mounting configurations (through-hole right-angle), and viewing angles (70°). The 5510803F's slightly higher luminous intensity (12.5mcd versus 12mcd) does not create compatibility issues.

Q: Are there differences in compliance or certifications between these parts? A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, MSL 1 rating, and ECCN/HTSUS classifications.

Q: What is the significance of the millicandela rating difference? A: The 5510803F provides 0.5mcd additional luminous intensity. This represents a minor brightness increase and does not affect electrical interface compatibility or circuit design parameters.

Q: Are these parts interchangeable at the PCB assembly level? A: Yes. Identical through-hole right-angle mounting specifications, lead configurations, and physical dimensions ensure direct PCB assembly compatibility without tooling or design changes.

Q: Which part should be selected for new designs? A: Selection should be based on current inventory availability and supply chain lead times. Both parts meet identical performance and compliance requirements for new applications.
