Dialight 5973312402F LED Green Clear 1206 SMD - Equivalent & Substitute Parts
Part Overview
The Dialight 5973312402F is a green LED indication component in 1206 (3016 Metric) surface mount package format. This discrete LED operates at 2.1V forward voltage with a dominant wavelength of 561nm and peak wavelength of 565nm, designed for standard LED indication applications. The component is classified as obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance requirements. Substitute parts must maintain electrical compatibility across forward voltage, current ratings, and mechanical fit within the 1206 package footprint.

Frequently Asked Questions (FAQ)
Q: Can the Lumex SML-LXL1206GC-TR be used as a direct replacement for the Dialight 5973312402F without circuit modification?
A: Yes. Both components share identical forward voltage (2.1V), test current (20mA), and package configuration (1206 SMD). No circuit redesign or component value changes are required for substitution.
Q: Are there differences in brightness between these two components?
A: The Dialight component is rated at 41.5mcd, while the Lumex substitute is rated at 20mcd. This represents a difference in luminous intensity. Applications requiring specific brightness levels should evaluate this parameter against functional requirements.
Q: Will the Lumex part fit the same PCB footprint as the Dialight component?
A: Yes. Both components use the 1206 (3016 Metric) package with identical dimensions (3.00mm L x 1.50mm W) and maximum height (1.50mm), ensuring mechanical compatibility with existing PCB designs.
Q: What is the viewing angle difference between these components?
A: The Dialight component has a 60° viewing angle, while the Lumex substitute has a 20° viewing angle. Applications requiring wide-angle visibility should account for this difference in optical performance.
Q: Are both components suitable for the same moisture and temperature environments?
A: Both components share identical Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), indicating equivalent handling and storage requirements during manufacturing and assembly processes.
Q: Does the Lumex substitute provide better regulatory compliance?
A: The Lumex substitute carries ROHS3 compliance certification, while the Dialight component status is not specified. Both maintain equivalent REACH Unaffected status and identical ECCN/HTSUS classifications.
