Key Parameters

Substitute Part Grouping Explanation

The Dialight 5520922F qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Electrical Specifications: Identical voltage rating (1.8V) and current consumption (2mA)
• Optical Characteristics: Matching wavelength (565nm), millicandela rating (1.8mcd), viewing angle (50°), and lens type (diffused, tinted)
• Configuration: Identical dual-level (2 High) green LED arrangement
• Mounting Interface: Identical through-hole, right-angle mounting configuration
• Environmental Compliance: Matching MSL rating (1), REACH status, ECCN, and HTSUS classification
• Series Continuity: Both parts belong to the Dialight 552 series

The primary distinction is product status: the 5520922 is obsolete while the 5520922F is active, with improved inventory availability (1704 pcs vs. 752 pcs) and RoHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5520922F is the appropriate selection for new designs and ongoing production requirements. This part maintains complete electrical and optical equivalence to the obsolete 5520922 while offering the following advantages:

• Active Product Status: The 5520922F is in active production, ensuring long-term availability and supply chain stability
• Regulatory Compliance: RoHS3 certification on the substitute part meets current environmental standards
• Inventory Availability: Significantly higher stock levels (1704 pcs) support production schedules without supply constraints
• Identical Specifications: All critical parameters—voltage, current, wavelength, brightness, viewing angle, and mounting configuration—are unchanged, ensuring direct functional replacement without circuit redesign

For legacy systems currently using the 5520922, the 5520922F provides a direct drop-in replacement with no modifications to PCB layout, electrical connections, or operational parameters required.

Frequently Asked Questions (FAQ)

Q: Can the 5520922F be used as a direct replacement for the 5520922 without PCB modifications?

A: Yes. The 5520922F is electrically and mechanically identical to the 5520922. Both parts share identical voltage ratings (1.8V), current consumption (2mA), mounting configuration (through-hole, right-angle), and optical specifications (565nm wavelength, 1.8mcd brightness, 50° viewing angle). No PCB layout changes are required.

Q: What is the primary reason for substituting the 5520922?

A: The 5520922 is classified as obsolete, creating supply and long-term availability risks. The 5520922F is an active product from the same manufacturer and series, providing assured supply and production continuity.

Q: Are there any compliance differences between these parts?

A: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99). The 5520922F carries additional RoHS3 certification, which represents an enhancement for regulatory compliance in current manufacturing environments.

Q: Do the lens specifications differ between these parts?

A: Both parts feature identical lens specifications: 5mm diffused, tinted lens with domed top. The 5520922F does not specify lens style and size in the available data, but maintains the same optical performance characteristics (wavelength, brightness, viewing angle).

Q: What is the MSL rating for both parts?

A: Both the 5520922 and 5520922F carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there packaging differences between the main part and substitute?

A: The 5520922 is specified with standard packaging, while the 5520922F is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact component performance or compatibility.
