Substitute Part Grouping Explanation

The substitute part 5505504F is qualified as a direct equivalent based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical color specification (Red)
• Identical wavelength peak (635nm)
• Identical current rating (20mA)
• Identical voltage rating (2.2V)
• Identical brightness output (125mcd)
• Identical viewing angle (24°)
• Identical lens configuration (Clear, Round with Domed Top)
• Identical physical form factor (5mm, T-1 3/4)
• Identical mounting type (Through Hole)
• Equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Equivalent moisture sensitivity level (MSL 1)

Both parts originate from Dialight and maintain Active product status, confirming long-term availability and manufacturing support.
