Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production Continuity:

The Everlight 573GD is obsolete and no longer in active production. Both substitute parts are classified as active and maintain full functional compatibility based on electrical and mechanical parameters.

Broadcom HLMP-0504 is suitable for applications where the narrower viewing angle of 100° is acceptable. This part provides ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. The forward voltage of 2.2V represents a 4.8% increase from the original specification and must be verified within circuit design tolerances.

Lumex SSL-LX25783GD is suitable for applications requiring wider light distribution, with a 110° viewing angle. This part also provides ROHS3 compliance and REACH unaffected status. The forward voltage of 2.0V represents a 4.8% decrease from the original specification and must be verified within circuit design tolerances.

Both substitutes are available in active inventory and carry identical ECCN and HTSUS classifications as the original component.

Frequently Asked Questions (FAQ)

Q: Can the Broadcom HLMP-0504 directly replace the Everlight 573GD in existing PCB designs?

A: Direct replacement is possible with circuit verification. The HLMP-0504 maintains identical lens style, mounting type, package configuration, and peak wavelength. The viewing angle is narrower (100° vs 180°), and forward voltage is 2.2V versus 2.1V. PCB layout compatibility depends on lens size tolerance (7.31 x 2.35mm vs 7.10 x 2.40mm) and height (8.00mm vs 8.10mm). Electrical circuit design must accommodate the 0.1V forward voltage difference.

Q: What is the primary difference between the two substitute parts?

A: The Broadcom HLMP-0504 features a 100° viewing angle, while the Lumex SSL-LX25783GD provides a 110° viewing angle. Both are narrower than the original 573GD at 180°. Forward voltage differs: HLMP-0504 at 2.2V and SSL-LX25783GD at 2.0V. Lens dimensions vary slightly between all three parts. Selection depends on specific application requirements for light distribution and circuit voltage tolerance.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the Broadcom HLMP-0504 and Lumex SSL-LX25783GD are ROHS3 compliant and REACH unaffected. The original Everlight 573GD compliance status is not specified in available documentation.

Q: What is the impact of forward voltage differences on circuit design?

A: The Broadcom HLMP-0504 operates at 2.2V (0.1V higher) and the Lumex SSL-LX25783GD at 2.0V (0.1V lower) compared to the original 2.1V specification. These differences affect current-limiting resistor calculations and power consumption. Circuit designs must be re-evaluated to ensure proper LED operation and brightness consistency within the application's tolerance band.

Q: Can viewing angle differences affect circuit performance?

A: Viewing angle affects light distribution characteristics but not electrical circuit performance. The original 573GD provides 180° viewing angle, while both substitutes offer narrower angles (100° and 110°). Application suitability depends on optical design requirements. Narrower viewing angles concentrate light intensity in a specific direction, which may be advantageous or disadvantageous depending on the indication application.

Q: Are the lens size differences significant for PCB layout?

A: Lens dimensions vary slightly: Everlight 573GD (7.10 x 2.40mm), Broadcom HLMP-0504 (7.31 x 2.35mm), and Lumex SSL-LX25783GD (7.00 x 2.30mm). Height also differs marginally (8.10mm, 8.00mm, and 8.00mm respectively). These differences are within typical PCB design tolerances for through-hole components but should be verified against specific mechanical constraints, particularly for high-density layouts or applications with tight mechanical clearances.
