Engineering Selection Recommendations

SSL-LXA228SYC Selection Criteria:

• Primary choice for applications requiring 300mcd brightness output
• Specified for 20mA test current operation
• 25° viewing angle for focused indication
• Active product status with continuous manufacturer support
• ROHS3 compliant for regulated environments

HLMP-6405 Selection Criteria:

• Alternative for applications tolerating 20mcd brightness output
• Operates at reduced 10mA test current, suitable for power-constrained designs
• 28° viewing angle provides wider light distribution
• Active product status with established supply chain (11,802 pcs inventory)
• ROHS3 compliant for regulated environments
• Lower moisture sensitivity level (2A vs 4) for extended storage conditions

Both components maintain active product status and full regulatory compliance. Selection between these parts depends on specific brightness requirements, current budget constraints, and viewing angle specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can HLMP-6405 directly replace SSL-LXA228SYC in existing designs?

A: Direct replacement requires verification of brightness requirements. The HLMP-6405 provides 20mcd output versus 300mcd for the SSL-LXA228SYC. Both maintain identical forward voltage (2V), axial through-hole mounting, and clear yellow lens characteristics. Designs tolerant of reduced brightness can use HLMP-6405 without PCB modification.

Q: What are the key electrical differences between these parts?

A: Forward voltage is identical at 2V nominal. Test current differs: SSL-LXA228SYC operates at 20mA while HLMP-6405 operates at 10mA. Brightness output differs significantly: 300mcd versus 20mcd respectively. Peak wavelength is nearly identical (585nm vs 583nm).

Q: Are the physical dimensions compatible for PCB footprints?

A: Both components use axial through-hole mounting with flat leads and identical package configuration. Lens diameter is nearly identical (1.90mm vs 1.91mm). Maximum height differs slightly (2.80mm vs 2.92mm). Standard axial LED footprints accommodate both components without modification.

Q: Do both parts meet the same regulatory requirements?

A: Both SSL-LXA228SYC and HLMP-6405 are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS code (8541.41.0000). Regulatory compliance is equivalent for both components.

Q: Which part should be selected for new designs?

A: Selection depends on application brightness requirements. For standard indication requiring 300mcd output, specify SSL-LXA228SYC. For power-constrained applications or designs tolerating lower brightness, HLMP-6405 provides equivalent functionality at reduced current consumption.
