Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the SSL-LX5063IC is based on strict alignment of the following parameters:

Critical Parameters (Must Match Exactly):

• Color: Red
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• Voltage - Forward (Vf) (Typ): 2V ± tolerance
• Current - Test: 20mA

Important Parameters (Should Match or Be Compatible):

• Lens Transparency: Clear
• Lens Style: Round with Domed Top
• Millicandela Rating: Within acceptable brightness range for application
• Viewing Angle: Within acceptable range for application
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed meet the critical parameters. Variations in millicandela rating, viewing angle, and physical height are noted where they differ from the main part specification, as these may affect application suitability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the SSL-LX5063IC. Selection among these alternatives depends on specific application requirements:

HLMP-D105 (Broadcom Limited): Forward voltage of 1.8V represents the lowest Vf among substitutes, requiring circuit recalculation if voltage drop is critical. Millicandela rating of 240mcd exceeds the main part. Physical height of 12.44mm is significantly greater than SSL-LX5063IC (6.00mm), which may impact PCB layout compatibility. Viewing angle of 24° is narrower than the main part.

LTL2R3KEK (Lite-On Inc.): Forward voltage of 2.05V is closest to the main part specification. Millicandela rating of 700mcd substantially exceeds the main part, suitable for applications requiring higher brightness. Viewing angle of 30° matches the main part exactly. Physical height of 8.70mm is moderately higher than the main part.

OVLLR8C7 (TT Electronics/Optek Technology): Forward voltage of 2V matches the main part exactly. Millicandela rating of 900mcd is the highest among substitutes. Lens style features a flat top rather than domed top, representing a physical difference. Viewing angle of 100° is significantly wider than the main part, suitable for wide-angle indication applications. Physical height of 6.80mm is closest to the main part.

WP1503EC (Kingbright): Forward voltage of 2V matches the main part exactly. Millicandela rating of 50mcd is substantially lower than the main part, suitable only for applications with reduced brightness requirements. Viewing angle of 30° matches the main part. Physical height of 8.60mm is moderately higher than the main part.

WP7113EC (Kingbright): Forward voltage of 2V matches the main part exactly. Millicandela rating of 100mcd is lower than the main part. Viewing angle of 20° is narrower than the main part. Physical height of 8.60mm is moderately higher than the main part.

Frequently Asked Questions (FAQ)

Q: Can HLMP-D105 be used as a direct replacement for SSL-LX5063IC?

A: HLMP-D105 meets the critical parameters of color, lens size, mounting type, and package configuration. However, the forward voltage of 1.8V differs from the 2V specification of SSL-LX5063IC, requiring circuit verification. The physical height of 12.44mm is significantly greater than 6.00mm, which may affect PCB layout. Viewing angle of 24° is narrower than 30°. Substitution is possible with circuit and layout review.

Q: What is the primary difference between LTL2R3KEK and SSL-LX5063IC?

A: Both components share identical forward voltage (2V) and viewing angle (30°) specifications. The primary difference is millicandela rating: LTL2R3KEK provides 700mcd compared to 160mcd for SSL-LX5063IC. This makes LTL2R3KEK suitable for applications requiring higher brightness output. Physical height differs by 2.70mm (8.70mm vs. 6.00mm).

Q: Is OVLLR8C7 compatible with SSL-LX5063IC in terms of electrical parameters?

A: Yes. OVLLR8C7 matches the forward voltage (2V) and current test specification (20mA) of SSL-LX5063IC. The lens style differs (flat top vs. domed top), and the viewing angle is substantially wider (100° vs. 30°). These optical differences may affect application suitability depending on the intended use case.

Q: Why do WP1503EC and WP7113EC have lower millicandela ratings than SSL-LX5063IC?

A: WP1503EC (50mcd) and WP7113EC (100mcd) are specified with lower brightness outputs compared to SSL-LX5063IC (160mcd). These components are suitable for applications where reduced brightness is acceptable or preferred, such as low-power indicator circuits or where brightness intensity must be limited.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—HLMP-D105, LTL2R3KEK, OVLLR8C7, WP1503EC, and WP7113EC—are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the regulatory and handling requirements of SSL-LX5063IC.

Q: What is the significance of the 30° viewing angle specification?

A: The viewing angle determines the cone of light emission from the LED. SSL-LX5063IC, LTL2R3KEK, and WP1503EC all specify 30° viewing angles, indicating similar directional light distribution. HLMP-D105 and WP7113EC have narrower angles (24° and 20° respectively), while OVLLR8C7 has a significantly wider angle (100°), affecting visibility from different positions relative to the LED.

Q: Can physical height differences affect PCB assembly?

A: Yes. SSL-LX5063IC has a maximum height of 6.00mm. Substitute parts range from 6.80mm to 12.44mm. Height differences may impact PCB layout, clearance requirements, and mechanical fit within enclosures. HLMP-D105 at 12.44mm represents the most significant height increase and requires layout verification before substitution.

Q: What wavelength information is provided for these components?

A: SSL-LX5063IC specifies a peak wavelength of 635nm. Substitute parts provide peak wavelengths ranging from 627nm to 645nm, all within the red spectrum. These wavelength variations are minor and reflect typical manufacturing tolerances across different manufacturers.
