Engineering Selection Recommendations

Primary Recommendation: SSL-LX5093SRC/E

The SSL-LX5093SRC/E is the manufacturer-recommended direct replacement for the SSL-LX5093SRC/DU. Both components share identical electrical parameters (1.7V forward voltage, 20mA test current, 660nm peak wavelength, 30° viewing angle) and mechanical specifications (5mm T-1 3/4 package, 8.60mm maximum height, through-hole radial configuration). The SSL-LX5093SRC/E is classified as active with ROHS3 compliance and unlimited moisture sensitivity rating. The primary difference is increased luminous intensity (2800mcd versus 1200mcd), which provides enhanced brightness margin without affecting circuit compatibility. Bulk packaging is available with 53,806 units in stock.

Secondary Recommendations for Brightness-Matched Applications:

For applications requiring luminous intensity closer to the original 1200mcd specification, the following active components provide suitable alternatives:

LTL2R3KEK (Lite-On Inc.): 700mcd at 2.05V forward voltage, 30° viewing angle, 8.70mm height. Maintains identical viewing angle and similar package height. ROHS3 compliant with 9,468 units in stock.
LTL2R3KRK (Lite-On Inc.): 680mcd at 2V forward voltage, 30° viewing angle, 8.70mm height. Comparable brightness and viewing angle performance. ROHS3 compliant with 6,132 units in stock.
LTL2P3KRK (Lite-On Inc.): 800mcd at 2V forward voltage, 22° viewing angle, 8.70mm height. Provides intermediate brightness level with slightly narrower viewing angle. ROHS3 compliant with 825 units in stock.

Considerations for Lower Brightness Applications:

HLMP-D105 (Broadcom Limited): 240mcd at 1.8V forward voltage, 24° viewing angle, 12.44mm height. Suitable for applications where reduced brightness is acceptable. Active status with 8,220 units in stock.
HLMP-D155-F0002 (Broadcom Limited): 10mcd at 1.7V forward voltage, 1mA test current, 24° viewing angle, 12.44mm height. Designed for low-current indicator applications. Tape & Reel packaging with 687 units in stock.

Compliance Status:

All recommended active substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The SSL-LX5093SRC/E, LTL2R3KEK, LTL2R3KRK, and LTL2P3KRK are REACH compliant or unaffected. All components carry EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093SRC/E directly replace SSL-LX5093SRC/DU without circuit modification?

A: Yes. The SSL-LX5093SRC/E maintains identical forward voltage (1.7V), test current (20mA), wavelength (660nm), viewing angle (30°), and mechanical package specifications. The increased luminous intensity (2800mcd versus 1200mcd) does not require circuit changes and provides additional brightness margin.

Q: What is the primary difference between SSL-LX5093SRC/DU and SSL-LX5093SRC/E?

A: Product status and luminous intensity. The SSL-LX5093SRC/DU is obsolete with 1200mcd output. The SSL-LX5093SRC/E is active with 2800mcd output. All other electrical and mechanical parameters are identical.

Q: Are Lite-On LTL2R3 series components compatible with the original SSL-LX5093SRC/DU?

A: LTL2R3KEK and LTL2R3KRK are compatible with circuit design modifications. Both maintain the 30° viewing angle and similar package height (8.70mm). However, forward voltage increases to 2.05V and 2V respectively, requiring circuit verification. Luminous intensity (700mcd and 680mcd) is closer to the original 1200mcd than other alternatives.

Q: What is the viewing angle difference between SSL-LX5093SRC/DU and HLMP-D105?

A: The SSL-LX5093SRC/DU provides a 30° viewing angle, while HLMP-D105 provides a 24° viewing angle. This represents a narrower field of view with HLMP-D105. Application requirements determine acceptability of this difference.

Q: Can I use 333-2SURC/S530-A2 from Everlight as a substitute?

A: 333-2SURC/S530-A2 is mechanically compatible (5mm round through-hole package, 8.90mm height) but presents electrical differences. Forward voltage increases to 2V, viewing angle narrows to 10°, and luminous intensity reduces to 837mcd. Circuit verification is required before implementation.

Q: What packaging options are available for substitute parts?

A: SSL-LX5093SRC/E, LTL2R3KEK, LTL2R3KRK, and LTL2P3KRK are available in bulk packaging. HLMP-D105 is available in bulk packaging with 8,220 units in stock. HLMP-D105-M0002 and HLMP-D155-F0002 are available in Tape & Reel (TR) packaging for automated assembly applications.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended active substitutes maintain ROHS3 compliance. Compliance status is verified for SSL-LX5093SRC/E, LTL2R3KEK, LTL2R3KRK, LTL2P3KRK, HLMP-D105, HLMP-D105-M0002, and HLMP-D155-F0002.

Q: What is the maximum height constraint for substitute components?

A: The original SSL-LX5093SRC/DU specifies 8.60mm maximum height. Substitute components range from 8.60mm to 12.44mm. Applications with height constraints below 8.70mm should prioritize SSL-LX5093SRC/E (8.60mm), LTL2R3KEK (8.70mm), LTL2R3KRK (8.70mm), or LTL2P3KRK (8.70mm).

Q: Which substitute provides the closest brightness match to the original 1200mcd?

A: LTL2P3KRK delivers 800mcd, representing the closest available brightness match among active components. LTL2R3KEK (700mcd) and LTL2R3KRK (680mcd) provide alternative options with identical 30° viewing angle to the original specification.

Q: Can HLMP-D155-F0002 replace SSL-LX5093SRC/DU in standard applications?

A: HLMP-D155-F0002 is designed for low-current indicator applications with 10mcd output and 1mA test current. This component is suitable only for applications where reduced brightness and current consumption are design requirements. Standard indication applications require higher brightness alternatives.
