Substitute Part Grouping Explanation

The Dialight 5520933F qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical color specification: Yellow (x 2)
• Identical configuration: 2 High
• Identical lens dimensions and style: 5mm, T-1 3/4, Round with Domed Top, Diffused, Tinted
• Identical mounting type: Through Hole, Right Angle
• Identical electrical ratings: 1.9V, 2mA
• Identical optical performance: 583nm wavelength, 1.8mcd, 50° viewing angle
• Identical moisture sensitivity level: MSL 1 (Unlimited)

The primary distinction between the main part and substitute is product status and packaging configuration.
