Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3UWC8.030C is determined by the following critical parameters:

Primary Compatibility Criteria:

• Mounting Type: Through Hole (radial configuration)
• Lens Size: 3mm T-1 form factor
• Lens Style: Round with Domed Top
• Lens Transparency: Clear colorless
• Color: White (cool or standard white acceptable)
• Voltage - Forward (Vf): Range 3.2V to 3.5V
• Current - Test: 20mA nominal
• Millicandela Rating: Minimum 7500mcd (brightness within acceptable tolerance)
• Viewing Angle: 25° to 35° (acceptable variation for indication applications)
• Package / Case: Radial configuration

The substitute part 5218268F meets these criteria within the specified electrical and mechanical tolerances for direct functional replacement in through-hole LED indication circuits.

Engineering Selection Recommendations

The 5218268F from Dialight is a qualified substitute for the obsolete 3UWC8.030C. Selection is supported by the following factors:

Product Status Alignment: The substitute part is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Electrical Compatibility: Forward voltage differential of 0.1V (3.3V vs. 3.4V) is within acceptable tolerance for standard LED indication circuits. Test current remains constant at 20mA, requiring no circuit redesign.

Optical Performance: The substitute delivers 9300mcd brightness compared to 8000mcd, providing enhanced visibility margin. Viewing angle variance of 5° (25° vs. 30°) remains acceptable for indication applications within standard PCB mounting geometries.

Mechanical Compatibility: Both components utilize identical 3mm T-1 through-hole radial configuration with round domed top clear lens. Height variance of 1.46mm is accommodated within standard PCB clearance specifications for indication LEDs.

Compliance Status: The substitute part maintains MSL 1 (Unlimited) moisture sensitivity rating and carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. The 0.1V forward voltage difference and identical 20mA test current require no circuit redesign. Standard LED current-limiting resistor calculations remain valid.

Q: What is the significance of the 1.46mm height difference?

A: The 5218268F maximum height of 6.56mm versus 3UWC8.030C at 5.10mm represents a 1.46mm increase. This variance is accommodated within standard PCB clearance specifications for through-hole indication LEDs and does not affect mechanical fit in typical applications.

Q: Does the higher brightness rating (9300mcd vs. 8000mcd) affect circuit operation?

A: No. The substitute's higher brightness provides enhanced visibility margin while maintaining identical test current (20mA). Existing current-limiting resistor values remain appropriate.

Q: Are there viewing angle considerations for substitution?

A: The 5° viewing angle reduction (25° vs. 30°) is acceptable for indication applications. Verify final viewing angle requirements against specific application geometry if narrow-angle visibility is critical.

Q: What compliance certifications apply to the substitute part?

A: The 5218268F carries ROHS3 Compliance and REACH Unaffected status, meeting current environmental and regulatory requirements equivalent to the main part.

Q: Is the substitute part currently available?

A: Yes. The 5218268F is in active production status with 5695 pieces in stock, providing reliable supply continuity for the obsolete 3UWC8.030C.
