Parameter Comparison

Engineering Selection Recommendations

The 5218268F from Dialight is a direct functional substitute for the obsolete 3UWC8.030N. Selection is supported by the following engineering factors:

Product Status: The 5218268F maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete 3UWC8.030N.

Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent export and tariff treatment.

Moisture Sensitivity: Both components are rated MSL 1 (Unlimited), indicating identical moisture handling and storage requirements.

RoHS and Environmental Compliance: The 5218268F is ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Electrical Parameters: The forward voltage differential of 0.1V (3.4V versus 3.3V) is within standard circuit design tolerances for LED indication applications. Both components operate at 20mA test current.

Optical Performance: The 5218268F provides 9300mcd brightness, exceeding the 8000mcd specification of the original part. The 25° viewing angle is narrower than the original 30°, which is acceptable for most indication applications but should be verified for wide-angle viewing requirements.

Mechanical Fit: The 5218268F height of 6.56mm exceeds the original 5.10mm by 1.46mm. PCB layout clearance must be verified to confirm compatibility with existing mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5218268F directly replace the 3UWC8.030N without circuit modification?

A: The 5218268F is electrically compatible with a 0.1V forward voltage difference. Existing current-limiting resistor values designed for 3.4V operation will function with the 3.3V substitute. No circuit modification is required for standard indication applications.

Q: What is the significance of the viewing angle difference (30° versus 25°)?

A: The 5218268F has a narrower viewing angle, meaning the LED brightness is concentrated in a tighter cone. For applications requiring wide-angle visibility, this difference may be significant. For direct front-panel indication, the narrower angle is typically acceptable.

Q: Does the increased height of the 5218268F (6.56mm versus 5.10mm) affect PCB assembly?

A: The 1.46mm height increase must be verified against PCB layout constraints, component clearances, and enclosure design. If the original design has minimal vertical clearance, mechanical interference may occur. Physical verification is necessary before production implementation.

Q: Are there any supply chain advantages to using the 5218268F?

A: Yes. The 5218268F is actively manufactured by Dialight with 5695 pieces in current inventory, compared to the obsolete 3UWC8.030N with limited remaining stock of 736 pieces. The active status ensures long-term procurement availability.

Q: What is the brightness difference between the two components?

A: The 5218268F provides 9300mcd compared to the 3UWC8.030N at 8000mcd, representing a 16.25% brightness increase. For indication applications, this enhanced brightness is generally beneficial and does not require circuit adjustment.

Q: Are both components identical in terms of regulatory classification?

A: Yes. Both components share ECCN EAR99 and HTSUS 8541.41.0000 classifications, confirming identical export control and tariff treatment. Both are MSL 1 (Unlimited) for moisture sensitivity.

Q: What should be verified before finalizing the substitution?

A: Verification should include: (1) PCB layout clearance for the increased 6.56mm height, (2) optical performance confirmation for the 25° viewing angle in the specific application context, and (3) mechanical fit within the enclosure or assembly.
