LED CBI 2MM Yellow Through Hole 5611201050

Part Overview

The Dialight 5611201050 is a Circuit Board Indicator (CBI) LED featuring a 2.00mm diameter round diffused lens with a flat top. This single yellow LED operates at 1.9V with a 2mA current rating and delivers 1.8 millicandela of luminous intensity at a 583nm peak wavelength. The component is designed for through-hole mounting on printed circuit boards.

This part is classified as obsolete. Locating equivalent substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this LED specification remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5611201050 is determined by the following critical parameters that must remain constant or compatible:

• Color: Yellow (583nm peak wavelength)
• Configuration: Single LED
• Current Rating: 2mA
• Voltage Rating: 1.9V
• Mounting Type: Through Hole
• Lens Type: Diffused
• Viewing Angle: 50°
• Millicandela Rating: 1.8mcd

The substitute part 5611201050F maintains all electrical and optical characteristics of the original component. The primary difference is the lens size specification, which transitions from a 2.00mm diameter to a 5mm diameter form factor. This change affects the physical footprint and board layout compatibility but does not alter the electrical performance or optical output characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 5611201050F serves as the active production equivalent to the obsolete 5611201050. Both components share identical electrical specifications, optical output, and mounting methodology. The substitute part is ROHS3 compliant, whereas the original part does not meet RoHS requirements. Selection between these parts depends on regulatory and compliance requirements applicable to the end application.

The primary consideration for substitution is physical form factor compatibility. The 5611201050F features a 5mm lens diameter compared to the 2mm diameter of the original part. Circuit board layout, mounting hole spacing, and mechanical clearances must be evaluated to determine if the larger lens diameter can be accommodated within the existing design.

Frequently Asked Questions (FAQ)

Q: Can the 5611201050F be used as a direct replacement for the 5611201050?

A: Electrical and optical compatibility is complete. The 5611201050F delivers identical voltage, current, color, wavelength, brightness, and viewing angle. Physical compatibility depends on whether the 5mm lens diameter can fit within the available board space and mechanical constraints of the original design.

Q: What is the primary difference between these two parts?

A: The lens diameter differs. The 5611201050 has a 2.00mm diameter lens, while the 5611201050F has a 5mm diameter lens. All electrical and optical parameters remain identical.

Q: Does the 5611201050F meet modern compliance standards?

A: Yes. The 5611201050F is ROHS3 compliant and carries an Active product status. The original 5611201050 is RoHS non-compliant and obsolete.

Q: Are there any electrical parameter differences between these parts?

A: No. Both parts operate at 1.9V, draw 2mA current, and produce 1.8 millicandela of light output at 583nm wavelength.

Q: What mounting considerations apply to substitution?

A: Both parts use through-hole mounting. Verify that the printed circuit board layout accommodates the 5mm lens diameter of the substitute part and that mounting hole positions align with the original design.
