LED CBI Display 10-Segment Red 104990109

Part Overview

The Seeed Technology Co., Ltd model 104990109 is a LED Circuit Board Indicator bar display featuring 10 red segments in a DIP configuration. This component is designed for visual indication applications requiring a 10-wide LED bar array with individual segment control. The part is classified as Obsolete, making identification of compatible substitute components essential for ongoing design support and procurement continuity. The substitute part EADLBA10RA3 from Everlight Electronics Co Ltd maintains functional equivalence while offering active product status and current availability.

Key Parameters

Substitute Part Grouping Explanation

The EADLBA10RA3 qualifies as a functional substitute for 104990109 based on the following critical parameters:

Matching Parameters:

• Configuration: Bar - 10 Wide, DIP (identical electrical and mechanical layout)
• Color: Red (x 10) (identical optical output color)
• Voltage Rating: 2V (identical operating voltage)
• Current: 60mA (identical per-segment current specification)
• Lens Style: Rectangle with Flat Top (identical physical form factor)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)
• ECCN and HTSUS classifications (identical regulatory status)

Acceptable Parameter Variations:

• Wavelength - Peak: 632nm (substitute) vs. 633nm (original) — variation of 1nm within red spectrum tolerance
• Millicandela Rating: 17.6mcd (substitute) vs. 25mcd (original) — reduced luminous intensity; acceptable where brightness reduction is tolerable
• Lens Type: Diffused, White (substitute) vs. unspecified (original) — diffusion characteristic affects light distribution pattern
• Lens Size: 5.00mm x 1.70mm (substitute specification provided; original unspecified)

Substitution is valid where the reduced brightness of the EADLBA10RA3 (17.6mcd vs. 25mcd) does not compromise application requirements.

Parameter Comparison

Engineering Selection Recommendations

Use EADLBA10RA3 as substitute when:

• The application can tolerate a 30% reduction in luminous intensity (17.6mcd vs. 25mcd)
• DIP configuration with 10-segment bar layout is required
• 2V operating voltage and 60mA per-segment current specifications are fixed
• Red wavelength in the 632–633nm range is acceptable
• Current product availability and active manufacturing status are required
• RoHS3 compliance is a procurement requirement

Do not substitute if:

• The application requires the original 25mcd brightness specification
• Exact wavelength matching at 633nm is critical
• The original unspecified lens characteristics are functionally dependent

The EADLBA10RA3 is the documented substitute for 104990109 and maintains electrical and mechanical compatibility across all critical parameters except luminous intensity.

Frequently Asked Questions (FAQ)

Q: Why is 104990109 listed as Obsolete? A: The Seeed Technology Co., Ltd model 104990109 has been discontinued. The EADLBA10RA3 from Everlight Electronics Co Ltd is the active substitute for ongoing procurement and new designs.

Q: Are the DIP pin configurations identical between 104990109 and EADLBA10RA3? A: Yes. Both parts use Bar - 10 Wide, DIP configuration, ensuring mechanical and electrical compatibility in DIP socket applications.

Q: What is the brightness difference between these parts? A: The EADLBA10RA3 produces 17.6mcd per segment compared to 25mcd for the 104990109. This represents a 30% reduction in luminous intensity. Substitution is valid only where this reduced brightness does not compromise application visibility requirements.

Q: Are the operating voltages and currents the same? A: Yes. Both parts operate at 2V with 60mA per-segment current specification.

Q: What does "Diffused, White" lens type mean on the EADLBA10RA3? A: The diffused lens scatters light across a wider viewing angle, while the white diffuser material affects light transmission characteristics. This differs from the original part's unspecified lens type and may alter the light distribution pattern in the application.

Q: Is the EADLBA10RA3 RoHS compliant? A: Yes. The EADLBA10RA3 is ROHS3 Compliant. RoHS compliance status for the original 104990109 is not specified in available documentation.

Q: What is the wavelength difference between these parts? A: The EADLBA10RA3 has a peak wavelength of 632nm compared to 633nm for the 104990109. This 1nm variation is within normal red LED spectrum tolerance and does not affect functional compatibility.

Q: Can I use EADLBA10RA3 in existing designs using 104990109? A: Yes, provided the application can tolerate the 30% reduction in brightness (17.6mcd vs. 25mcd). All other electrical and mechanical parameters are compatible.

Q: What packaging is available for the EADLBA10RA3? A: The EADLBA10RA3 is supplied in Tube packaging. Original packaging for 104990109 is not specified.
