Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSL-LXA228ID is determined by the following critical parameters:

Mechanical Compatibility:

• Mounting type must be through-hole axial configuration
• Package format must be axial with flat leads
• Physical dimensions must accommodate standard PCB hole spacing

Optical Characteristics:

• Color specification: red LED
• Lens transparency: diffused
• Lens style: round with domed top
• Wavelength range: red spectrum (635-645nm acceptable)

Electrical Parameters:

• Forward voltage (Vf): 1.8V to 2V range
• Test current: 20mA standard
• Brightness rating: minimum 25mcd

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status
• ECCN EAR99 classification

The HLMP-Q100-N0000 from Broadcom Limited meets these substitution criteria while offering improved specifications in brightness (45mcd) and viewing angle (90°).

Engineering Selection Recommendations

Primary Substitute: HLMP-Q100-N0000

The HLMP-Q100-N0000 is the qualified substitute for the obsolete SSL-LXA228ID. Selection is based on the following engineering factors:

Product Status Alignment: The substitute part maintains active production status with Broadcom Limited, ensuring long-term component availability and supply chain continuity compared to the obsolete SSL-LXA228ID.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent applications.

Electrical Compatibility: The HLMP-Q100-N0000 operates at 1.8V forward voltage, which is within acceptable tolerance of the original 2V specification for standard LED indicator circuits. Both components are rated for 20mA test current, maintaining circuit design consistency.

Mechanical Fit: Axial through-hole mounting with flat leads is identical between components. Physical dimensions are comparable (SSL-LXA228ID: 2.50mm L x 2.00mm W x 2.80mm H; HLMP-Q100-N0000: 2.09mm L x 2.21mm W x 2.92mm H), accommodating standard PCB layouts without modification.

Optical Performance: The substitute provides enhanced brightness (45mcd versus 25mcd) and wider viewing angle (90° versus 50°), delivering improved visibility in indicator applications. Peak wavelength remains within the red spectrum (645nm versus 635nm), maintaining color consistency.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-Q100-N0000 directly replace the SSL-LXA228ID without circuit modification?

A: The HLMP-Q100-N0000 is mechanically and electrically compatible for direct substitution in through-hole axial LED indicator applications. The 0.2V forward voltage difference (1.8V versus 2V) is within standard LED circuit tolerance and does not require redesign of current-limiting resistor networks in typical indicator circuits.

Q: What are the key differences between these two components?

A: The primary differences are: (1) Product status—SSL-LXA228ID is obsolete while HLMP-Q100-N0000 is active production; (2) Brightness—HLMP-Q100-N0000 provides 45mcd versus 25mcd; (3) Viewing angle—HLMP-Q100-N0000 offers 90° versus 50°; (4) Peak wavelength—645nm versus 635nm, both within red spectrum. Physical dimensions are comparable with negligible variation.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both SSL-LXA228ID and HLMP-Q100-N0000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: What is the impact of the wider 90° viewing angle on circuit design?

A: The wider viewing angle of the HLMP-Q100-N0000 expands the angular range for indicator visibility without requiring circuit modification. This is a performance enhancement for applications requiring visibility from multiple viewing positions.

Q: Are there packaging differences between these components?

A: Both components use axial through-hole packaging with flat leads. The HLMP-Q100-N0000 is supplied in bulk packaging, while the SSL-LXA228ID was supplied in standard packaging. This does not affect component functionality or PCB integration.

Q: How does the brightness increase from 25mcd to 45mcd affect circuit operation?

A: The brightness increase does not require circuit modification. LED brightness is determined by forward current, which remains at 20mA test current for both components. The higher millicandela rating indicates improved light output efficiency at the same current level, enhancing indicator visibility without additional power consumption.
