Key Parameters

Substitute Part Grouping Explanation

The Dialight 5500204F qualifies as a direct substitute based on matching electrical and optical parameters across all critical selection criteria. Substitution validity is determined by the following parameters:

• Color and wavelength (Green, 565nm peak)
• Electrical specifications (2.1V forward voltage, 20mA forward current)
• Optical output (12.3mcd brightness rating)
• Viewing angle (60°)
• Lens characteristics (Diffused, 5mm form factor)
• Mounting configuration (Through Hole)
• Environmental compliance (REACH Unaffected, MSL 1)

The 5500204F maintains identical specifications across all these parameters, establishing it as a functional equivalent suitable for direct replacement in applications currently using the 5500204.

Parameter Comparison

Engineering Selection Recommendations

The 5500204F is the appropriate selection for applications currently specified with the 5500204. The obsolete status of the original part necessitates transition to the active equivalent. The 5500204F maintains full electrical and optical compatibility while offering ROHS3 compliance certification, providing enhanced regulatory alignment for new designs and ongoing production.

Current inventory availability favors the 5500204F (1757 pcs in stock) over the obsolete 5500204 (1081 pcs in stock), supporting supply chain continuity for both new production and field replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 5500204F directly replace the 5500204 in existing designs?

A: Yes. The 5500204F maintains identical electrical specifications (2.1V, 20mA), optical output (12.3mcd at 565nm), viewing angle (60°), and through-hole mounting configuration. No circuit modifications are required.

Q: What is the primary difference between these parts?

A: The 5500204 is classified as obsolete, while the 5500204F is an active product. The 5500204F includes ROHS3 compliance certification. Both parts are functionally equivalent.

Q: Are there packaging differences between the two parts?

A: Both parts are supplied in bulk packaging. The 5500204F does not specify lens style or size in available documentation, though electrical and optical parameters confirm compatibility with the 5mm, T-1 3/4 form factor of the original part.

Q: Which part should be selected for new designs?

A: The 5500204F should be specified for new designs due to its active product status and ROHS3 compliance. The 5500204 is no longer recommended for new applications.

Q: Are there any compliance or regulatory differences?

A: Both parts maintain REACH Unaffected status and MSL 1 rating. The 5500204F adds ROHS3 Compliant certification, providing additional regulatory alignment for applications subject to RoHS requirements.
