Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3BWDL-F is determined by the following critical parameters that must remain consistent across equivalent components:

Mandatory Matching Parameters:

• Color: Blue
• Lens Transparency: Diffused
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Wavelength - Peak: 430nm
• Viewing Angle: 35°
• Height (Max): 5.30mm
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Voltage - Forward (Vf): May vary within circuit design tolerance
• Current - Test: May vary based on application requirements
• Millicandela Rating: May vary based on brightness requirements
• Product Status: Active status preferred for obsolete components

The substitute part 3BWD-F maintains all mandatory matching parameters while offering enhanced electrical characteristics suitable for modern applications.

Parameter Comparison

Engineering Selection Recommendations

The 3BWD-F serves as the direct substitute for the obsolete 3BWDL-F. Both components are manufactured by Bivar Inc. and share identical mechanical and optical specifications, including lens configuration, mounting type, and physical dimensions.

The 3BWD-F is classified as Active product status, ensuring continued availability and supply chain reliability. The substitute part carries ROHS3 compliance certification, meeting current environmental and regulatory standards for electronic component manufacturing.

The electrical differences between the main part and substitute—specifically the forward voltage increase from 3.8V to 4V and test current increase from 2mA to 20mA—reflect enhanced performance characteristics. The 3BWD-F delivers 10 millicandela compared to the 2.5 millicandela of the 3BWDL-F, providing increased luminous intensity for indicator applications.

Circuit design must accommodate the higher forward voltage and test current specifications of the 3BWD-F. Resistor values and power supply considerations require adjustment to maintain proper LED operation within specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the 3BWD-F directly replace the 3BWDL-F without circuit modification?

A: The 3BWD-F maintains identical mechanical and optical specifications, allowing physical installation in existing through-hole PCB layouts. However, the increased forward voltage (4V versus 3.8V) and test current (20mA versus 2mA) require circuit recalculation. Series resistor values must be adjusted to accommodate the higher electrical requirements.

Q: What are the key compatibility factors for substitution?

A: Compatibility is determined by matching color (blue), lens transparency (diffused), lens size (3mm T-1), mounting type (through hole), package configuration (radial), wavelength (430nm peak), viewing angle (35°), and physical height (5.30mm maximum). The 3BWD-F satisfies all these requirements.

Q: Why does the 3BWD-F have higher millicandela rating?

A: The 10mcd rating of the 3BWD-F reflects modern LED technology advancement compared to the 2.5mcd of the obsolete 3BWDL-F. This increased brightness is a result of improved semiconductor efficiency and does not affect mechanical or optical compatibility.

Q: Is the 3BWD-F suitable for new designs?

A: The 3BWD-F is classified as Active product status with ROHS3 compliance, making it appropriate for new product development and long-term production requirements.

Q: What packaging options are available for the 3BWD-F?

A: The 3BWD-F is supplied in bulk packaging, differing from the main part specification. Packaging format does not affect component electrical or mechanical performance.
