Dialight 5510209010F LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5510209010F is an LED Circuit Board Indicator (CBI) designed for through-hole, right-angle mounting applications. This single green diffused LED features a 3.00mm domed lens and operates at 2.1V with 20mA current consumption, delivering 16mcd brightness at a 45° viewing angle. The component is classified as Active product status and maintains full compliance with RoHS3, REACH Unaffected, and MSL 1 (Unlimited) specifications. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit functional alternatives.

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5510209010F are identified based on strict electrical and mechanical parameter alignment. The substitution logic is organized into two categories:

Direct Equivalent (5510209806F): This Dialight part maintains identical specifications across all critical parameters: green color, 563nm wavelength, 20mA current, 16mcd brightness, 45° viewing angle, 2.1V voltage rating, 3.00mm domed lens, through-hole right-angle mounting, and equivalent compliance certifications. This part is classified as a direct equivalent due to complete parameter matching within the same manufacturer series.

Similar Substitute (WP934CB/GD): This Kingbright part provides functional substitution with minor parameter variations. The key parameters remain compatible: green color, similar wavelength (565nm vs 563nm), identical 20mA current, comparable brightness (22.5mcd vs 16mcd), similar viewing angle (40° vs 45°), marginally higher voltage rating (2.2V vs 2.1V), and equivalent lens style and mounting configuration. The 3mm T-1 lens size is mechanically compatible with the 3.00mm specification. All compliance certifications match the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The Dialight 5510209010F remains the specified component for applications requiring exact parameter matching and Dialight series continuity.

Direct Equivalent Selection: The Dialight 5510209806F is suitable as a direct replacement when supply constraints affect the primary part. This part maintains identical electrical and mechanical specifications, ensuring seamless integration without circuit redesign or board layout modification.

Alternative Manufacturer Selection: The Kingbright WP934CB/GD is suitable for applications where minor parameter variations are acceptable within design tolerances. The increased brightness (22.5mcd vs 16mcd) and marginally higher voltage rating (2.2V vs 2.1V) are compatible with standard indicator circuit designs. The 40° viewing angle remains suitable for most panel-mount applications. All three parts maintain equivalent compliance certifications (RoHS3, REACH Unaffected, MSL 1), ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Kingbright WP934CB/GD be used as a direct replacement for the Dialight 5510209010F?

A: The Kingbright WP934CB/GD is functionally compatible as a substitute. The primary differences are increased brightness (22.5mcd vs 16mcd), slightly higher voltage rating (2.2V vs 2.1V), marginally narrower viewing angle (40° vs 45°), and equivalent lens sizing (3mm T-1 vs 3.00mm). These variations are within acceptable tolerances for standard indicator applications. Circuit design and board layout remain unchanged.

Q: What is the difference between the Dialight 5510209010F and 5510209806F?

A: Both parts are Dialight Series 551 components with identical electrical and mechanical specifications. The 5510209806F serves as a direct equivalent with no functional differences. Selection between these parts is determined by inventory availability and procurement lead times.

Q: Are all three parts RoHS3 compliant?

A: Yes. The Dialight 5510209010F, Dialight 5510209806F, and Kingbright WP934CB/GD are all ROHS3 Compliant with REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does the higher brightness of the Kingbright part affect circuit design?

A: No. All three parts operate at identical 20mA current consumption. The increased brightness of the Kingbright part (22.5mcd vs 16mcd) results from lens and phosphor optimization, not increased current draw. Existing circuit designs require no modification.

Q: Are the lens sizes mechanically compatible?

A: Yes. The 3mm T-1 lens specification of the Kingbright WP934CB/GD is mechanically compatible with the 3.00mm domed lens of the Dialight parts. Through-hole mounting and right-angle configuration are identical across all three parts.
