Substitute Part Grouping Explanation

Substitution within the XLamp® ML-C series is determined by electrical and mechanical parameter compatibility. All substitute parts maintain identical specifications for forward voltage (6.4V), test current (50mA), maximum current (175mA), luminous flux (38lm at 25°C, 50mA), luminous efficacy (119 lm/W), CRI (75 Typ), viewing angle (120°), package configuration (4-SMD J-Lead Exposed Pad), physical dimensions (4.60mm × 3.15mm), height (1.33mm), thermal resistance (13°C/W), and compliance certifications (RoHS, REACH, MSL 2A).

The primary variable across substitute parts is color temperature (CCT), which ranges from 5000K to 6500K. This parameter does not affect electrical performance, thermal characteristics, or mechanical compatibility. Selection of substitute parts should be based on application color temperature requirements while maintaining all other electrical and mechanical specifications.

Engineering Selection Recommendations

The MLCSWT-A1-0000-0001E1 is classified as "Not For New Designs." For new designs requiring 6500K color temperature, MLCSWT-A1-0000-000151 is the direct active equivalent, maintaining identical electrical and mechanical specifications with Active product status.

All substitute parts listed are manufactured by CreeLED, Inc., carry Active product status, and maintain full compliance with RoHS and REACH regulations. All parts are classified as MSL 2A with 4-week moisture sensitivity windows. Selection among substitute parts should be based solely on color temperature requirements for the application.

For applications requiring color temperatures other than 6500K, the following active alternatives are available: 5000K (MLCSWT-A1-0000-0001A1, MLCSWT-A1-0000-0001DZ, MLCSWT-A1-0000-0001E3), 5500K (MLCSWT-A1-0000-0001DY), 5750K (MLCSWT-A1-0000-0001E2), and 6000K (MLCSWT-A1-0000-0001DV). All alternatives maintain identical forward voltage, current ratings, luminous flux, efficacy, CRI, viewing angle, package configuration, and thermal characteristics.
