Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSL-LX5063IT are qualified based on the following criteria:

Mandatory Matching Parameters:

• Color: Red
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Allowable Variation Parameters:

• Voltage - Forward (Vf): ±0.3V tolerance acceptable for 2V nominal devices
• Current - Test: Operating current may vary within circuit design limits
• Millicandela Rating: Brightness variation acceptable if application does not require specific luminous intensity
• Wavelength - Peak: Red spectrum range (617nm to 660nm) acceptable for general indication applications
• Viewing Angle: Variation acceptable based on circuit board layout requirements
• Height (Max): Physical clearance variation acceptable within PCB design constraints

All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and active product status, ensuring long-term availability and regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

WP7113IT (Kingbright): This substitute maintains identical forward voltage (2V) and test current (20mA) as the SSL-LX5063IT. The WP7113IT provides higher luminous intensity (100mcd versus 50mcd), making it suitable for applications requiring increased brightness. The narrower viewing angle (20° versus 30°) may require circuit board layout verification. Height difference of 2.6mm requires PCB clearance confirmation. ROHS3 compliance and active product status ensure regulatory and supply chain continuity.

SLR-56VC3F (Rohm Semiconductor): This substitute matches the 2V forward voltage specification but operates at reduced test current (10mA versus 20mA). The SLR-56VC3F provides lower luminous intensity (25mcd versus 50mcd) and wider viewing angle (40° versus 30°). The 630nm dominant wavelength remains within red spectrum parameters. Height of 8.90mm requires PCB clearance verification. ROHS3 compliance and active product status are maintained.

HLMP-D155 (Broadcom Limited): This substitute operates at reduced forward voltage (1.7V versus 2V) and significantly reduced test current (1mA versus 20mA). The HLMP-D155 provides substantially lower luminous intensity (10mcd versus 50mcd). The 660nm peak wavelength remains within red spectrum range. Maximum height of 12.44mm requires PCB clearance confirmation. ROHS3 compliance and active product status are maintained. Circuit design modifications may be necessary to accommodate lower operating current.

All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and active product status. Selection depends on specific application requirements for brightness, viewing angle, and PCB physical constraints.

Frequently Asked Questions (FAQ)

Q: Can WP7113IT directly replace SSL-LX5063IT without circuit modification?

A: WP7113IT maintains identical forward voltage (2V) and test current (20mA), enabling direct replacement in most applications. However, the increased brightness (100mcd versus 50mcd) and narrower viewing angle (20° versus 30°) require verification against application requirements. PCB clearance must be confirmed due to 2.6mm height difference.

Q: What are the key differences between SSL-LX5063IT and HLMP-D155?

A: HLMP-D155 operates at lower forward voltage (1.7V versus 2V) and significantly reduced test current (1mA versus 20mA). Luminous intensity is substantially lower (10mcd versus 50mcd). Circuit design modifications are required to accommodate these electrical differences. Direct substitution without design review is not recommended.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SSL-LX5063IT, WP7113IT, SLR-56VC3F, and HLMP-D155 are all ROHS3 compliant with unlimited MSL rating (1), ensuring regulatory alignment and long-term supply chain stability.

Q: What is the wavelength compatibility range for red LED substitution?

A: All substitute parts operate within the red spectrum range (617nm to 660nm peak/dominant wavelength). The SSL-LX5063IT operates at 635nm peak wavelength. Wavelength variation within this range is acceptable for general indication applications where specific spectral characteristics are not required.

Q: Do substitute parts require PCB layout modifications?

A: All substitute parts use identical 5mm T-1 3/4 through-hole radial package configuration. However, height variations (6.00mm to 12.44mm) may require PCB clearance verification. Viewing angle differences may necessitate circuit board placement review to ensure optical performance meets application requirements.

Q: Which substitute provides the closest electrical match to SSL-LX5063IT?

A: WP7113IT provides the closest electrical match, maintaining identical forward voltage (2V) and test current (20mA). This substitute is recommended for applications where electrical parameter consistency is critical.

Q: Can SLR-56VC3F operate at the same current as SSL-LX5063IT?

A: SLR-56VC3F is rated for 10mA test current versus 20mA for SSL-LX5063IT. Operating at 20mA may exceed component specifications. Circuit design must be verified to ensure operation within SLR-56VC3F electrical limits.
