Substitute Part Grouping Explanation

The 5500305F qualifies as a direct substitute for the 5500305 based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Color: Yellow (585nm peak wavelength)
• Configuration: Single LED
• Current rating: 20mA
• Voltage rating: 2.1V
• Optical output: 12.3mcd at 60° viewing angle
• Lens specifications: Diffused, round with domed top, 5mm T-1 3/4
• Mounting: Through hole, right angle orientation
• Moisture sensitivity: MSL 1 (Unlimited)

The 5500305F maintains identical specifications to the main part while offering active product status and ROHS3 compliance, with the primary difference being packaging format (bulk versus standard).

Parameter Comparison

Engineering Selection Recommendations

The 5500305F is the appropriate selection for applications currently using the obsolete 5500305. Both parts maintain identical electrical performance and mechanical form factor, ensuring direct compatibility in circuit board designs without layout modifications.

The 5500305F offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, ROHS3 compliance of the 5500305F aligns with current regulatory requirements for electronic components in most markets.

For new designs or production transitions, the 5500305F should be specified to avoid future obsolescence issues associated with the 5500305.
