Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSF-LXH475GD is determined by the following critical parameters that must align across equivalent parts:

Primary Compatibility Criteria:

• Configuration: 4 High (quad LED arrangement)
• Color: Green (x 4)
• Wavelength - Peak: 565nm
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused, Tinted
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Electrical Parameters (allowable variance):

• Voltage Rating: 2.1V to 2.2V
• Current: 10mA to 25mA per LED
• Millicandela Rating: 12.6mcd to 30mcd
• Viewing Angle: 40° to 60°

The identified substitute parts maintain the core functional architecture (quad green LED configuration with right-angle through-hole mounting) while operating within acceptable electrical parameter ranges. Both substitute parts are active products with current manufacturing status, ensuring long-term supply availability.

Parameter Comparison

Engineering Selection Recommendations

5680102222F (Dialight) - Lower Current Application:

This substitute is suitable for applications where reduced power consumption is acceptable. Operating at 10mA versus the original 20mA, this part delivers 12.6mcd brightness with a 60° viewing angle matching the original specification. The lower current rating reduces thermal load and power supply requirements. Dialight's active product status ensures continued availability and manufacturing support. ROHS3 compliance and unlimited moisture sensitivity rating align with the original part's environmental specifications.

WP934SB/4GD (Kingbright) - Matched Voltage Application:

This substitute operates at 2.2V, identical to the original SSF-LXH475GD, with 25mA current and 25mcd brightness. The viewing angle is reduced to 40° compared to the original 60°, which may impact visibility in applications requiring wide-angle illumination. Kingbright's active product status provides long-term supply assurance. ROHS3 compliance and unlimited moisture sensitivity rating maintain environmental compatibility with the original design.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. Selection between substitutes depends on specific application requirements regarding current draw, brightness, and viewing angle constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5680102222F replace the SSF-LXH475GD in all applications?

A: The 5680102222F operates at half the current (10mA versus 20mA) and delivers lower brightness (12.6mcd versus 30mcd). It is suitable for applications where reduced brightness and lower power consumption are acceptable. The 60° viewing angle matches the original specification. Verify that the application's brightness requirements are met before substitution.

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

A: The 5680102222F (Dialight) operates at 10mA with 12.6mcd brightness, while the WP934SB/4GD (Kingbright) operates at 25mA with 25mcd brightness. The Kingbright part has a narrower viewing angle (40° versus 60°). The Dialight part is packaged in bulk; the Kingbright part is packaged in tubes.

Q: Are both substitute parts RoHS compliant?

A: Yes, both 5680102222F and WP934SB/4GD are ROHS3 compliant and REACH unaffected, matching the original SSF-LXH475GD specifications.

Q: Does the lens size difference affect mechanical compatibility?

A: The substitute parts feature 3mm, T-1 round lenses with domed tops, while the original part's lens size is not specified in the provided data. Verify mechanical fit within the PCB mounting holes and surrounding component layout before implementation.

Q: Which substitute is closer to the original electrical specifications?

A: The WP934SB/4GD matches the original voltage rating (2.2V) and provides closer brightness output (25mcd versus 30mcd). The 5680102222F operates at a lower voltage (2.1V) and significantly reduced current and brightness levels.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on application-specific requirements for brightness, current draw, and viewing angle. The quad green LED configuration and right-angle through-hole mounting are consistent across all three parts. Electrical parameter differences require design review before substitution.
