Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSL-LXA228SGC is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color: Green
• Lens Transparency: Clear
• Mounting Type: Through Hole, Axial
• Package Configuration: Axial, Flat Leads
• Wavelength Range: 565nm peak wavelength band

Secondary Compatibility Parameters:

• Forward Voltage (Vf): 2.1V to 2.2V range
• Millicandela Rating: 40mcd to 50mcd range
• Viewing Angle: 25° to 28° range
• Lens Size: 1.90mm to 1.91mm diameter
• Physical Dimensions: Compatible axial form factor

The HLMP-6505 manufactured by Broadcom Limited meets all primary and secondary substitution criteria, establishing it as a direct functional equivalent for the obsolete SSL-LXA228SGC.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-6505 is the qualified substitute for the obsolete SSL-LXA228SGC based on the following engineering criteria:

Compliance & Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production environments.

Electrical Compatibility: Forward voltage differential of 0.1V (2.1V vs 2.2V) falls within acceptable tolerance for standard LED circuit designs. The substitute operates at lower test current (10mA vs 20mA), indicating improved efficiency characteristics.

Optical Performance: Peak wavelength alignment at 565nm ensures color matching for green indication applications. The 40mcd brightness rating of the HLMP-6505 represents 80% of the original SSL-LXA228SGC specification, suitable for indication-class applications where absolute brightness is not critical.

Mechanical & Thermal Compatibility: Axial through-hole mounting configuration, flat lead design, and lens dimensions (1.91mm vs 1.90mm) ensure direct PCB footprint compatibility without layout modifications.

Supply & Availability: The HLMP-6505 maintains active product status with 960,200 units in stock, providing long-term supply security compared to the obsolete SSL-LXA228SGC.

Storage Considerations: The HLMP-6505 carries MSL 2A rating (4-week moisture sensitivity) versus MSL 1 for the original part. Standard moisture control procedures during storage and handling are required.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-6505 be used as a direct drop-in replacement for the SSL-LXA228SGC?

A: Yes. Both components share identical mounting type (through-hole axial), package configuration (axial flat leads), and physical form factor. No PCB layout modifications are required.

Q: What is the brightness difference between these components?

A: The HLMP-6505 provides 40mcd versus the SSL-LXA228SGC's 50mcd. For indication applications, this 10mcd reduction is functionally acceptable. Applications requiring the original 50mcd specification must evaluate alternative sources.

Q: Are there forward voltage compatibility concerns?

A: The 0.1V difference (2.1V vs 2.2V) is within standard LED circuit tolerance. Existing series resistor calculations remain valid without modification for typical indicator circuits.

Q: What does the higher MSL rating on the HLMP-6505 mean?

A: MSL 2A (4 weeks) requires components to be stored in controlled humidity environments and used within 4 weeks of bag opening. Standard moisture-barrier packaging and dry storage conditions address this requirement.

Q: Is the viewing angle difference significant?

A: The HLMP-6505 provides a 28° viewing angle versus 25° for the original part. This wider angle improves visibility and is compatible with all applications designed for the SSL-LXA228SGC.

Q: Do both components meet current regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.

Q: What is the wavelength specification for these green LEDs?

A: Both components specify 565nm peak wavelength, ensuring color consistency for green indication applications across the substitution.
