Key Parameters

Substitute Part Grouping Explanation

The Dialight 5522388F qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Manufacturer: Dialight (same manufacturer, Series 552)
• Color: Blue (x 2) with identical 470nm peak wavelength
• Configuration: 2 High (dual-element arrangement)
• Current Rating: 20mA (identical operating current)
• Voltage Rating: 3.8V (identical operating voltage)
• Viewing Angle: 30° (identical optical specification)
• Mounting Type: Through Hole, Right Angle (identical mechanical interface)
• Moisture Sensitivity Level: 1 (Unlimited) - identical environmental rating
• REACH Status: REACH Unaffected (identical compliance)
• ECCN: EAR99 (identical export classification)
• HTSUS: 8541.41.0000 (identical tariff classification)

Differing Parameters:

• Lens Type: Clear (5522388) vs. Tinted (5522388F)
• Lens Style: Not specified (5522388) vs. Round with Domed Top (5522388F)
• Lens Size: Not specified (5522388) vs. 5mm, T-1 3/4 (5522388F)
• Millicandela Rating: 1010mcd (5522388) vs. 520mcd (5522388F)
• Product Status: Obsolete (5522388) vs. Active (5522388F)
• RoHS Status: Not specified (5522388) vs. ROHS3 Compliant (5522388F)

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5522388F is the designated substitute for the obsolete Dialight 5522388. Both components share identical electrical specifications (3.8V, 20mA, 470nm wavelength) and mechanical mounting interfaces (through-hole, right-angle configuration). The substitute maintains equivalent REACH compliance and export classification status.

The primary distinction is the brightness output: the 5522388F delivers 520mcd compared to the original 1010mcd. This reduction in luminous intensity must be evaluated against application-specific visibility requirements. The 5522388F features an active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5522388F be used as a direct replacement for the 5522388?

A: The 5522388F is electrically and mechanically compatible with the 5522388, sharing identical voltage (3.8V), current (20mA), wavelength (470nm), and mounting configuration (through-hole, right-angle). The primary consideration is the reduced brightness output (520mcd vs. 1010mcd), which must be assessed for your specific application requirements.

Q: What are the key differences between these two parts?

A: The main differences are: (1) Brightness: 5522388 provides 1010mcd while 5522388F provides 520mcd; (2) Lens configuration: 5522388 has a clear lens, while 5522388F has a tinted lens with round domed top (5mm, T-1 3/4); (3) Product status: 5522388 is obsolete while 5522388F is active; (4) Compliance: 5522388F includes ROHS3 certification.

Q: Are the mounting footprints identical?

A: Yes. Both components use through-hole, right-angle mounting with identical mechanical interfaces, allowing direct PCB layout compatibility.

Q: What is the impact of the lens type difference?

A: The 5522388 features a clear lens while the 5522388F has a tinted lens with a round domed top. This affects light transmission characteristics and optical appearance but does not alter the fundamental 470nm wavelength specification or 30° viewing angle.

Q: Is the 5522388F compliant with current environmental regulations?

A: Yes. The 5522388F is ROHS3 compliant and maintains REACH Unaffected status, identical to the original 5522388. Both components carry EAR99 export classification and 8541.41.0000 HTSUS tariff code.

Q: Why is the 5522388 listed as obsolete?

A: The 5522388 has been discontinued by Dialight. The 5522388F represents the active product line continuation within the 552 series, offering equivalent functionality with modern compliance certifications.
