Frequently Asked Questions (FAQ)

Q: Can the 5554303F be used as a direct replacement for the 5554303?

A: Yes. The 5554303F maintains identical electrical performance (5V, 4.7mA), optical characteristics (565nm green, 2.5mcd, 40° viewing angle), and mechanical form factor (2.00mm through-hole right-angle mount). All critical substitution parameters are matched.

Q: What is the primary difference between these parts?

A: The 5554303 is obsolete with RoHS non-compliant status, while the 5554303F is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between the two parts?

A: The 5554303 is specified with dash packaging notation, while the 5554303F is supplied in bulk packaging. This distinction does not affect component functionality or performance.

Q: Does the RoHS compliance change affect circuit design?

A: No. RoHS compliance status reflects manufacturing process and material composition but does not alter electrical performance, voltage rating, current draw, or optical output characteristics.

Q: Are both parts suitable for 5V applications?

A: Yes. Both the 5554303 and 5554303F are rated for 5V operation at 4.7mA per LED element in the quad configuration.
