Substitute Part Grouping Explanation

Substitute parts for the 5513508803F are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Dual color configuration (Green and Red)
• Diffused lens type with domed top geometry
• Voltage compatibility within specified ranges (2.1V-2.2V Green, 2V Red)
• Current rating capability (minimum 20mA per color)
• RoHS3 and REACH compliance alignment
• Through-hole or surface-mount mounting compatibility

The identified substitutes (SSF-LXH169SISUGW and WP59BL/EGW) share the core functional parameters of dual-color LED indication with diffused optics. However, these parts feature 5mm lens diameter and right-angle through-hole mounting, representing a form-factor change from the original 3mm axial configuration. This substitution is valid where PCB layout accommodates the larger package footprint and right-angle orientation.

Parameter Comparison

Engineering Selection Recommendations

SSF-LXH169SISUGW (Lumex Opto/Components Inc.): This substitute maintains Active product status with full RoHS3 and REACH compliance. The part delivers significantly higher luminous intensity (200mcd Green, 500mcd Red) compared to the original, suitable for applications requiring enhanced visibility. The 60° viewing angle provides moderate directional characteristics. Right-angle through-hole mounting requires PCB layout modification from the original axial configuration. Current rating reduction from 30mA to 20mA per color necessitates circuit design review for brightness optimization.

WP59BL/EGW (Kingbright): This substitute is Active with full RoHS3 and REACH compliance. The part features a narrower 30° viewing angle, appropriate for applications requiring focused indication. Luminous intensity is moderate (60mcd Green, 40mcd Red), closer to the original brightness profile than the Lumex alternative. Right-angle through-hole mounting requires PCB layout modification. Current rating reduction to 20mA per color requires circuit design adjustment.

Both substitutes are suitable for applications where PCB layout can accommodate 5mm right-angle through-hole mounting and where the reduced current requirement aligns with circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5513508803F be directly replaced with SSF-LXH169SISUGW or WP59BL/EGW without PCB modification?

A: No. The original part features 3mm axial mounting, while both substitutes use 5mm right-angle through-hole configuration. PCB layout modification is required to accommodate the different form factor and mounting orientation.

Q: What is the impact of the current rating reduction from 30mA to 20mA?

A: The substitute parts operate at 20mA per color versus the original 30mA. Circuit designs must be reviewed to ensure adequate brightness at the lower current level. The substitutes provide higher luminous intensity (200mcd and 60mcd Green respectively) which partially compensates for the reduced current.

Q: Are the wavelength differences significant?

A: The wavelength variations are minor. Original: 560nm Green/630nm Red. SSF-LXH169SISUGW: 574nm Green/636nm Red. WP59BL/EGW: 565nm Green/627nm Red. These differences fall within standard LED color perception tolerances and do not affect functional compatibility.

Q: Which substitute provides brightness closest to the original?

A: The WP59BL/EGW (60mcd Green, 40mcd Red) provides a closer brightness profile to the original (12mcd Green, 8mcd Red) compared to the SSF-LXH169SISUGW (200mcd Green, 500mcd Red). However, both substitutes deliver higher luminous intensity than the original part.

Q: Are both substitutes suitable for all applications?

A: Substitution suitability depends on specific application requirements. The SSF-LXH169SISUGW is appropriate for applications requiring high visibility. The WP59BL/EGW is suitable for applications with moderate brightness requirements and narrow viewing angle specifications. Both require PCB layout modification and circuit design review for current rating compatibility.

Q: Do the substitutes maintain the same compliance certifications?

A: Yes. Both substitutes are RoHS3 Compliant and REACH Unaffected, matching the original part's regulatory status.
