Engineering Selection Recommendations

Direct Substitute (Preferred):

SSL-LX3044GD-12V is the direct substitute for SSL-LX3054GD-12V. Both parts are manufactured by Lumex Opto/Components Inc., share identical electrical specifications (12V forward voltage, 6mcd brightness), optical characteristics (green diffused, 565nm peak wavelength, 60° viewing angle), and mechanical form factor (3mm T-1 through-hole radial package). The only variance is maximum height (4.60mm vs 5.25mm), which represents a reduced envelope suitable for space-constrained applications. Both parts maintain Active product status and ROHS3 compliance.

Voltage-Compatible Substitutes:

HLMP-1641 (Broadcom Limited) operates at 12V forward voltage matching the main part specification. This part maintains identical lens size, style, and mounting configuration. However, brightness is reduced to 1.6mcd compared to 6mcd of the SSL-LX3054GD-12V. This part is suitable for applications where lower brightness is acceptable or preferred. ROHS3 compliance and Active status are maintained.

Alternative Voltage Operation:

Parts operating at different forward voltages (HLMP-1640 at 5V, HLMP-1503-C0002 at 2.1V, HLMP-1790 at 1.9V, 3GD-F at 2.1V, LTL-4231 at 2.1V) require circuit redesign to accommodate different voltage requirements and current limiting resistor values. These parts are not direct substitutes but represent alternative solutions for different power supply architectures. All listed alternatives maintain green color, diffused lens, 3mm T-1 form factor, and through-hole mounting.

All substitute parts listed maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and Active product status.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3044GD-12V replace SSL-LX3054GD-12V directly without circuit modification?

A: Yes. SSL-LX3044GD-12V is a direct substitute with identical electrical and optical specifications. The reduced maximum height (4.60mm vs 5.25mm) may provide design advantages in space-constrained layouts. No circuit changes are required.

Q: What is the primary difference between SSL-LX3054GD-12V and HLMP-1641?

A: Both operate at 12V forward voltage with identical lens configuration and 60° viewing angle. The primary difference is brightness: SSL-LX3054GD-12V provides 6mcd while HLMP-1641 provides 1.6mcd. HLMP-1641 is suitable for applications requiring lower brightness indication.

Q: Can HLMP-1640 (5V) be used in place of SSL-LX3054GD-12V (12V)?

A: No direct substitution is possible without circuit redesign. HLMP-1640 requires 5V forward voltage operation, necessitating different current limiting resistor calculations and potentially different power supply architecture. The parts share identical lens size, style, and mounting type but operate at different voltage levels.

Q: Are all listed substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance status. LTL-4231 is noted as REACH Affected, while all other parts are REACH Unaffected.

Q: What viewing angle differences exist among the substitute parts?

A: SSL-LX3054GD-12V and its direct substitute SSL-LX3044GD-12V both provide 60° viewing angle. HLMP-1641 also provides 60°. Alternative voltage parts show variation: HLMP-1640 provides 60°, HLMP-1790 provides 50°, 3GD-F provides 35°, and LTL-4231 provides 40°. Viewing angle selection depends on application requirements for light distribution.

Q: What is the inventory status for substitute parts?

A: SSL-LX3044GD-12V has 5,644 pieces in stock. HLMP-1641 has 4,525 pieces. HLMP-1640 has 21,912 pieces. HLMP-1790 has 24,307 pieces. LTL-4231 has 44,239 pieces. Availability varies by part number and supplier.

Q: Do all parts use the same packaging?

A: SSL-LX3054GD-12V uses standard packaging. SSL-LX3044GD-12V is supplied in Bulk packaging. Broadcom parts (HLMP series) are supplied in Bulk or Cut Tape (CT) depending on specific part number. Bivar 3GD-F and Lite-On LTL-4231 are supplied in Bulk. Packaging selection may affect procurement and handling procedures.
