Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Lens size: 3mm T-1 form factor
• Mounting type: Through-hole radial configuration
• Lens style: Round with domed top
• Lens transparency: Clear
• Color family: White (warm or neutral white acceptable)
• Voltage range: Forward voltage within acceptable circuit design tolerance (3.3V to 3.4V)
• Current rating: 20mA test current compatibility
• Package classification: Radial

Substitution Logic: The Dialight 5218268F qualifies as a functional substitute based on matching lens geometry, mounting configuration, and electrical operating parameters. Both components operate at similar forward voltages (3.3V vs 3.4V) and test currents (20mA), enabling direct circuit compatibility. The substitute maintains the same physical form factor and radial package type required for through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility: The Dialight 5218268F is a valid functional substitute for the obsolete Bivar 3UWC8.030W based on matching electrical and mechanical parameters. Both components share identical lens geometry, mounting configuration, and test current specifications.

Product Status Consideration: The 3UWC8.030W is classified as obsolete, while the 5218268F is in active production status. This status differential ensures long-term component availability and supply chain continuity for the substitute part.

Compliance and Certification: The 5218268F carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent export and tariff treatment.

Physical Integration Considerations: The substitute component exhibits a maximum height of 6.56mm compared to the original 5.10mm specification. This 1.46mm height difference requires verification against PCB layout constraints and enclosure clearance specifications in the target application.

Electrical Performance Variance: The forward voltage differential of 0.1V (3.3V substitute vs 3.4V original) is within acceptable tolerance for LED indication circuits and does not require circuit redesign. The substitute provides increased brightness (9300mcd vs 8000mcd) and a narrower viewing angle (25° vs 30°), which may be advantageous or require consideration depending on application requirements.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5218268F be used as a direct replacement for the Bivar 3UWC8.030W without circuit modification?

A: Yes. Both components operate at compatible forward voltages (3.3V vs 3.4V) and identical test currents (20mA). The 0.1V variance does not require circuit redesign for standard LED indication applications. Physical form factor and mounting type are identical.

Q: What is the significance of the height difference between these components?

A: The substitute (5218268F) is 1.46mm taller than the original (6.56mm vs 5.10mm). This difference must be evaluated against PCB layout constraints, enclosure height limitations, and any mechanical clearance requirements in the target application. Verify that the increased height does not create interference with adjacent components or enclosure geometry.

Q: Does the higher brightness rating of the substitute affect circuit compatibility?

A: No. The increased millicandela rating (9300mcd vs 8000mcd) does not affect electrical circuit compatibility. Both components operate at identical test currents. The brightness increase may be beneficial for visibility in the target application but does not require circuit modification.

Q: How does the narrower viewing angle of the substitute impact application suitability?

A: The substitute has a 25° viewing angle compared to the original 30° angle. This narrower viewing angle concentrates light output in a more focused beam. Evaluate whether the target application requires the wider viewing angle of the original component or if the narrower angle is acceptable for the intended indication function.

Q: What compliance advantages does the substitute provide?

A: The 5218268F carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements. The original component status is not specified. Both components share identical export classification (EAR99) and tariff codes (8541.41.0000).

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in bulk packaging, while the original packaging specification is listed as a dash (not specified). Both components use identical radial package configuration suitable for through-hole PCB assembly. Verify bulk packaging compatibility with your procurement and assembly processes.

Q: What is the supply status difference between these components?

A: The original Bivar component is classified as obsolete with 888 pieces in stock. The Dialight substitute is in active production status with 5695 pieces in stock, ensuring long-term availability and supply chain continuity for future procurement requirements.
