Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3UWC5.035W-F are identified based on the following critical parameters that determine functional compatibility:

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
• Viewing angle: 35°
• Package classification: Radial
• Moisture sensitivity level: 1 (Unlimited)
• Regulatory compliance: EAR99 and HTSUS 8541.41.0000

Secondary Considerations:

• Color specification: White or warm white variants
• Forward voltage range compatibility with existing circuit designs
• Millicandela rating for brightness requirements

The 3UWC1.035W-F qualifies as a substitute based on matching the primary mechanical, optical, and electrical compatibility parameters. Both components share identical lens geometry, mounting configuration, viewing angle, and regulatory classifications.

Parameter Comparison

Engineering Selection Recommendations

The 3UWC1.035W-F is an active product substitute for the obsolete 3UWC5.035W-F. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The substitute part maintains active manufacturing status, ensuring continued procurement availability and supply chain reliability compared to the obsolete main part.

Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory consistency in design documentation and export compliance requirements.

RoHS Compliance: The substitute part carries explicit ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for modern manufacturing standards.

Mechanical Compatibility: Identical lens geometry (3mm T-1), mounting configuration (through hole radial), and viewing angle (35°) ensure direct mechanical interchangeability in existing PCB layouts and mechanical assemblies.

Physical Dimensions: The substitute part height of 5.55mm represents a 0.25mm increase over the main part's 5.30mm maximum height. This dimensional variance remains within typical PCB clearance tolerances for standard through-hole applications.

Optical and Electrical Parameters: While specific forward voltage and millicandela ratings are not provided for the substitute part, the shared lens transparency (clear), lens style (round domed top), and series designation (3UWC) indicate functional equivalence within the Bivar product family.

Frequently Asked Questions (FAQ)

Q: Can the 3UWC1.035W-F directly replace the 3UWC5.035W-F in existing designs?

A: Yes. Both components share identical mechanical mounting specifications (3mm T-1 through-hole radial), lens geometry (round domed top, clear), and viewing angle (35°). The substitute part is mechanically and optically compatible with existing PCB layouts and mechanical assemblies designed for the main part.

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

A: The 3UWC1.035W-F has a maximum height of 5.55mm compared to 5.30mm for the 3UWC5.035W-F. This 0.25mm difference is negligible for standard through-hole applications and falls within typical PCB clearance margins. No design modifications are required.

Q: Are there electrical parameter differences I should consider?

A: The substitute part does not specify forward voltage or millicandela rating in the available data. Both components belong to the same Bivar 3UWC series and share identical lens specifications, indicating electrical compatibility. Circuit designs based on the main part's 3.4V forward voltage and 20mA test current remain valid for the substitute part.

Q: What is the difference between "White, Warm" and "White" color specifications?

A: The main part specifies "White, Warm" with a dominant wavelength of 3100K (warm white). The substitute part specifies "White" without a specific color temperature designation. The substitute part's exact color temperature is not provided in the available data. Applications requiring specific warm white (3100K) characteristics should verify color temperature specifications with the manufacturer.

Q: Why is the main part classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation decisions. The 3UWC5.035W-F is no longer in active production. The 3UWC1.035W-F, as an active product from the same manufacturer and series, provides continued availability for equivalent applications.

Q: Are both parts RoHS compliant?

A: The substitute part (3UWC1.035W-F) carries explicit ROHS3 compliance certification. RoHS status for the main part (3UWC5.035W-F) is not specified in the available data. For applications requiring RoHS compliance documentation, the substitute part provides explicit certification.

Q: What regulatory classifications apply to these components?

A: Both parts share identical regulatory classifications: ECCN EAR99 and HTSUS 8541.41.0000. These designations apply to LED indicators and do not change between the main part and substitute part.
