Parameter Comparison

Engineering Selection Recommendations

SSL-LXA228SRC-TR21 (Primary Component) Select this part when the application requires maximum brightness output at 600mcd with the widest viewing angle of 25°. The 1.7V forward voltage specification provides the lowest power consumption among the available options. The Yoke Bend package configuration is suitable for applications requiring specific PCB layout geometry. All regulatory certifications are current and active production status ensures supply continuity.

AM2520EC03 (Kingbright - Gull Wing Configuration) This substitute is applicable when circuit design requires a Gull Wing package configuration instead of Yoke Bend. The 50mcd brightness rating is suitable for indicator applications requiring lower light output. Forward voltage of 2V and 20° viewing angle represent moderate specifications. Improved MSL rating of 3 (168 Hours) provides extended moisture protection compared to the primary part. Standard Surface Mount configuration accommodates conventional PCB assembly processes.

AM2520EC09 (Kingbright - Z-Bend Configuration) This substitute maintains bottom entry mounting capability matching the primary part while offering Z-Bend package geometry. The 50mcd brightness and 2V forward voltage are identical to AM2520EC03. The Z-Bend configuration provides alternative mechanical lead geometry for specific PCB design requirements. MSL rating of 3 (168 Hours) exceeds the primary part specification. This option is selected when bottom entry mounting is required with alternative lead configuration.

HLMP-Q106-R0011 (Broadcom - High Brightness Alternative) This substitute provides 400mcd brightness output, positioning it between the primary part (600mcd) and Kingbright options (50mcd). The 1.9V forward voltage closely matches the primary part specification. The 15° viewing angle is narrower than other options, suitable for focused indication applications. Superior MSL rating of 2A (4 Weeks) provides maximum moisture protection. Gull Wing package configuration requires standard SMD assembly compatibility. Slightly different physical dimensions (2.09mm L x 2.21mm W) require PCB layout verification.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility with the primary component.

Frequently Asked Questions (FAQ)

Q: Can AM2520EC03 replace SSL-LXA228SRC-TR21 in a bottom entry mounting application?

A: AM2520EC03 uses standard Surface Mount configuration without bottom entry capability. The primary part specifies Surface Mount, Bottom Entry mounting type. For bottom entry applications, use AM2520EC09 instead, which maintains the bottom entry mounting specification while offering Kingbright sourcing.

Q: What is the brightness difference between SSL-LXA228SRC-TR21 and the Kingbright substitutes?

A: SSL-LXA228SRC-TR21 provides 600mcd brightness. Both Kingbright substitutes (AM2520EC03 and AM2520EC09) provide 50mcd brightness. This represents a 12:1 reduction in light output. Select Kingbright parts only when lower brightness is acceptable for the application.

Q: Are the physical dimensions identical across all substitute options?

A: SSL-LXA228SRC-TR21, AM2520EC03, and AM2520EC09 share identical dimensions of 2.50mm L x 2.00mm W with 2.90mm maximum height. HLMP-Q106-R0011 has slightly different dimensions of 2.09mm L x 2.21mm W with 2.92mm maximum height. PCB layout verification is required when substituting with the Broadcom part.

Q: What forward voltage differences exist among these parts?

A: SSL-LXA228SRC-TR21 operates at 1.7V (lowest power consumption). HLMP-Q106-R0011 operates at 1.9V. Both Kingbright parts (AM2520EC03 and AM2520EC09) operate at 2.0V (highest power consumption). Circuit design must accommodate the 0.3V maximum difference in forward voltage specifications.

Q: Which substitute offers the best moisture protection?

A: HLMP-Q106-R0011 provides MSL rating of 2A (4 Weeks), the highest moisture protection. AM2520EC03 and AM2520EC09 provide MSL rating of 3 (168 Hours). SSL-LXA228SRC-TR21 provides MSL rating of 4 (72 Hours), the lowest protection level. Select based on storage and assembly environment requirements.

Q: Can HLMP-Q106-R0011 be used as a direct replacement for SSL-LXA228SRC-TR21?

A: HLMP-Q106-R0011 is functionally compatible as a red LED indicator with 400mcd brightness and 1.9V forward voltage. However, the narrower viewing angle of 15° versus 25°, different lens size (1.78mm versus 1.90mm), and slightly different physical dimensions require application-specific evaluation. Standard Surface Mount configuration (no bottom entry) must be verified against PCB design requirements.

Q: What is the wavelength difference between these parts?

A: SSL-LXA228SRC-TR21 has peak wavelength of 660nm (deep red). HLMP-Q106-R0011 has peak wavelength of 654nm (red). Both Kingbright parts have peak wavelength of 627nm (red-orange). The 33nm maximum difference may be visible in color-critical applications. Verify color perception requirements before substitution.

Q: Are all parts available in the same packaging format?

A: All parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly. Package configurations differ: SSL-LXA228SRC-TR21 uses Yoke Bend, AM2520EC03 uses Gull Wing, AM2520EC09 uses Z-Bend, and HLMP-Q106-R0011 uses Gull Wing. Lead geometry differences require pick-and-place equipment compatibility verification.
