Substitute Part Grouping Explanation

Substitution logic for the SSL-LX3054GT is based on the following critical parameters: lens size (3mm T-1), mounting type (through-hole radial), color (green), lens transparency (clear), and package compatibility. All substitute parts maintain these core mechanical and optical characteristics.

The substitute parts differ in electrical specifications: forward voltage (Vf), millicandela rating (brightness), viewing angle, and wavelength characteristics. These electrical differences determine application suitability based on circuit design requirements.

Key substitution criteria:

Lens size and form factor: 3mm T-1 through-hole radial
Color and transparency: Green clear lens
Mounting configuration: Radial through-hole
Compliance: ROHS3 compliant, REACH unaffected
Moisture sensitivity: MSL 1 (unlimited)

Engineering Selection Recommendations

Active Status Parts: HLMP-1520, HLMP-1521, HLMP-Y502-F0000, HLMP-Y802-F0000, WP132XGT, WP710A10GT, and WP710A10PGT are all Active status components suitable for new designs and ongoing production.

Not For New Designs: SLR-332MC3F carries "Not For New Designs" status and should be used only for legacy system maintenance or replacement applications where the original part specification is required.

Compliance Considerations: All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the SSL-LX3054GT regulatory requirements.

Voltage Compatibility: The SSL-LX3054GT operates at 12V forward voltage, which differs significantly from all substitute parts operating at 2.1V to 2.25V. Circuit redesign is required when substituting this component. The substitute parts are designed for low-voltage applications and cannot be directly interchanged without circuit modification.

Brightness and Viewing Angle Trade-offs: Substitute selection depends on application requirements. HLMP-Y802-F0000 offers the highest brightness (240mcd) for applications requiring maximum visibility. HLMP-Y502-F0000 and WP132XGT provide 40mcd brightness with wider viewing angles (55° and 50° respectively) compared to the SSL-LX3054GT's 30° angle.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3054GT be directly replaced with any of these substitute parts?

A: No. The SSL-LX3054GT operates at 12V forward voltage while all substitute parts operate at 2.1V to 2.25V. Direct substitution requires circuit redesign to accommodate the different voltage requirements. The mechanical form factor (T-1 through-hole radial) is compatible, but electrical circuit integration differs fundamentally.

Q: Which substitute part most closely matches the SSL-LX3054GT brightness?

A: HLMP-Y502-F0000 (40mcd) and WP132XGT (40mcd) provide brightness closest to the SSL-LX3054GT's 50mcd rating. HLMP-Y802-F0000 offers significantly higher brightness at 240mcd for applications requiring enhanced visibility.

Q: Are all substitute parts suitable for new designs?

A: Seven of the eight substitute parts are Active status. SLR-332MC3F is marked "Not For New Designs" and should be used only for legacy system maintenance. For new designs, select from HLMP-1520, HLMP-1521, HLMP-Y502-F0000, HLMP-Y802-F0000, WP132XGT, WP710A10GT, or WP710A10PGT.

Q: What is the difference between HLMP-1520 and HLMP-1521?

A: Both parts share identical electrical specifications (2.1V, 22mcd, 45° viewing angle, 565nm peak wavelength) and physical dimensions (6.35mm height). They belong to the same HLMP-152x series. Selection between them depends on inventory availability and supplier preference.

Q: How does viewing angle affect substitution?

A: The SSL-LX3054GT has a 30° viewing angle, providing narrow-angle illumination. Substitute parts range from 30° to 85° viewing angles. Wider angles (HLMP-Y502-F0000 at 55°, SLR-332MC3F at 85°) distribute light over a broader area, while narrower angles concentrate light in a specific direction. Application requirements determine the appropriate viewing angle.

Q: What are the height differences among substitute parts?

A: Heights range from 4.60mm (SLR-332MC3F) to 6.35mm (HLMP-1520, HLMP-1521). The SSL-LX3054GT is 5.25mm. Height differences may affect PCB layout and mechanical clearance. Verify physical space constraints before selection.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed substitute parts, including the SSL-LX3054GT, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
