Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Seeed 104990124 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Configuration: 8 x 8 matrix layout
• Color: Red LED wavelength (660nm range)
• Internal Connection: Common Anode Row, Common Cathode Column topology
• Package Footprint: 38mm square form factor
• Moisture Sensitivity Level: MSL 1 classification

The Kingbright TC15-11SRWA satisfies all primary substitution criteria. Both components share identical matrix configuration, color specification, internal connection architecture, and MSL rating. The physical dimensions remain within acceptable tolerance for standard PCB mounting applications, with the substitute measuring 38.10mm x 38.10mm x 10.40mm compared to the original 38.00mm x 38.00mm x 7.20mm.

Parameter Comparison

Engineering Selection Recommendations

The Kingbright TC15-11SRWA serves as a direct functional substitute for the obsolete Seeed 104990124 based on the following engineering criteria:

Product Status Alignment: The Seeed 104990124 is classified as obsolete, while the Kingbright TC15-11SRWA maintains active product status with current manufacturing availability. This transition ensures continued supply chain access and component procurement capability.

Compliance and Certification: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory equivalence. The Kingbright TC15-11SRWA carries RoHS3 compliance and REACH unaffected status, meeting contemporary environmental and safety standards.

Electrical and Mechanical Compatibility: The substitute maintains identical matrix configuration (8x8), color specification (red), and internal connection topology (common anode row, common cathode column). The forward voltage specification of 1.85V for the substitute provides defined electrical operating parameters. The physical dimensions remain compatible within standard PCB assembly tolerances, with height variation of 3.20mm representing acceptable clearance margin for typical mounting applications.

Performance Characteristics: The Kingbright TC15-11SRWA delivers 49mcd brightness compared to the original 40mcd rating, providing enhanced luminous intensity without requiring circuit redesign. This performance increase maintains backward compatibility with existing driver circuits and control logic.

Frequently Asked Questions (FAQ)

Q: Can the Kingbright TC15-11SRWA directly replace the Seeed 104990124 in existing PCB designs?

A: Yes. Both components share identical 8x8 matrix configuration, common anode row/common cathode column internal connection, and 38mm square footprint. The substitute's 1.85V forward voltage specification aligns with standard LED driver circuit design parameters. The height difference of 3.20mm (0.28" to 0.41") requires verification of available PCB clearance in the mounting area.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) identical 8x8 matrix configuration, (2) matching red color specification, (3) identical common anode row/common cathode column internal connection topology, (4) compatible 38mm square package footprint, and (5) matching MSL 1 moisture sensitivity classification. All parameters must align for functional equivalence.

Q: Does the higher brightness rating (49mcd vs. 40mcd) of the substitute create compatibility issues?

A: No. The increased brightness of the Kingbright TC15-11SRWA does not create compatibility issues. Existing driver circuits and control logic designed for the original 40mcd component will operate the substitute without modification. The higher luminous intensity represents an enhancement rather than a deviation from specified operating parameters.

Q: Are there regulatory or compliance differences between the two components?

A: No. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The Kingbright TC15-11SRWA carries RoHS3 compliance and REACH unaffected status, meeting current environmental standards. No regulatory barriers exist to substitution.

Q: What packaging and inventory considerations apply to this substitution?

A: The Seeed 104990124 is obsolete with 839 units in stock. The Kingbright TC15-11SRWA is actively manufactured with 1011 units in current inventory. For new designs or ongoing production requirements, the Kingbright component ensures sustained supply chain access and eliminates obsolescence risk.
