LED BLUE T-1 3/4 5BWC-F Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5BWC-F is a blue LED indication component featuring a clear lens with 30mcd brightness rating, designed for through-hole mounting applications. This part operates at 4V forward voltage with a 430nm peak wavelength and 25° viewing angle. The 5BWC-F is classified as obsolete, necessitating identification of equivalent substitute components that maintain functional compatibility while ensuring continued design support and supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 5BWC-F are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Blue
• Mounting Type: Through Hole
• Package Type: Radial
• Lens Style: Round with Domed Top
• Operating Current: 20mA test current

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): 3.3V to 4V range
• Wavelength - Peak: 430nm to 470nm range
• Lens Transparency: Clear or Diffused
• Millicandela Rating: Brightness level for indication purposes

The 5BWC-F has two identified substitutes: the 5BWD-F (Bivar Inc., same manufacturer, active status) and the 6324-15SUBC/S400-X10 (Everlight Electronics Co Ltd, active status). Both maintain through-hole radial mounting and blue color specification. Variations in forward voltage, brightness rating, viewing angle, and lens transparency reflect design trade-offs within the blue LED indication component category.

Parameter Comparison

Engineering Selection Recommendations

5BWD-F Selection Criteria: The 5BWD-F is manufactured by Bivar Inc., the same original manufacturer as the 5BWC-F, and maintains active product status. This substitute shares identical forward voltage (4V), current rating (20mA), lens size (5mm T-1 3/4), and maximum height (8.60mm). The primary differences are lens transparency (diffused vs. clear), brightness reduction (15mcd vs. 30mcd), and increased viewing angle (40° vs. 25°). The 5BWD-F is RoHS3 compliant. Selection of this substitute is appropriate when the diffused lens characteristic and lower brightness are acceptable for the application.

6324-15SUBC/S400-X10 Selection Criteria: The 6324-15SUBC/S400-X10 is manufactured by Everlight Electronics Co Ltd and maintains active product status. This substitute operates at a lower forward voltage (3.3V vs. 4V) and provides significantly higher brightness (500mcd vs. 30mcd) with a wider viewing angle (60° vs. 25°). The lens size is slightly smaller (4.60mm vs. 5mm) and maximum height is substantially reduced (4.90mm vs. 8.60mm). Selection of this substitute requires verification that the lower forward voltage and different physical dimensions are compatible with the circuit design and mechanical layout.

Both substitutes maintain through-hole radial mounting, blue color, and 20mA test current specifications. Component selection depends on specific application requirements regarding brightness, viewing angle, forward voltage, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 5BWD-F directly replace the 5BWC-F in all applications?

A: The 5BWD-F shares the same manufacturer, forward voltage, current rating, lens size, and height as the 5BWC-F. The diffused lens and lower brightness (15mcd vs. 30mcd) may affect visual appearance and indicator visibility. Applications requiring the original 30mcd brightness or clear lens transparency require evaluation before substitution.

Q: What are the key differences between the 5BWD-F and 6324-15SUBC/S400-X10?

A: The 5BWD-F maintains the original 4V forward voltage and 5mm lens size, while the 6324-15SUBC/S400-X10 operates at 3.3V with a 4.60mm lens size. The 6324-15SUBC/S400-X10 provides 500mcd brightness compared to 15mcd for the 5BWD-F. Circuit voltage compatibility and physical space constraints determine which substitute is appropriate.

Q: Does the 6324-15SUBC/S400-X10 require circuit modifications?

A: The 6324-15SUBC/S400-X10 operates at 3.3V forward voltage compared to the 5BWC-F at 4V. Applications designed for 4V operation require circuit analysis to determine if voltage adjustment is necessary. The significantly higher brightness (500mcd) may also require current limiting resistor adjustment.

Q: Are both substitutes through-hole mounted components?

A: Yes, both the 5BWD-F and 6324-15SUBC/S400-X10 are through-hole mounted radial package components, maintaining compatibility with the original 5BWC-F mounting type.

Q: What is the significance of the 5BWC-F obsolete status?

A: The 5BWC-F is classified as obsolete, indicating discontinued manufacturing and limited future availability. The identified substitutes (5BWD-F and 6324-15SUBC/S400-X10) both maintain active product status, ensuring continued supply chain support and availability for new designs or component replenishment.

Q: How do viewing angles affect substitute selection?

A: The 5BWC-F has a 25° viewing angle, the 5BWD-F has 40°, and the 6324-15SUBC/S400-X10 has 60°. Wider viewing angles distribute light over a larger area, affecting indicator visibility from different angles. Applications requiring narrow-angle indication may be affected by substitutes with wider viewing angles.
