3BWD LED Blue Diffused T-1 Through Hole

Part Overview

The 3BWD is a blue diffused LED indicator in a T-1 through-hole package, designed for 4V discrete radial applications. Manufactured by Bivar Inc., this part is currently obsolete, making it necessary to identify suitable alternative components for new designs and ongoing production support. The 3BWD-S variant provides an active product status equivalent with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 3BWD-S serves as a parametric equivalent to the 3BWD, maintaining strict compatibility across all specified electrical and mechanical parameters. The substitution is based on the following criteria, all of which are identical between the main part and substitute:

• Color: Blue
• Lens Transparency: Diffused
• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Voltage - Forward (Vf) (Typ): 4V
• Current - Test: 20mA
• Millicandela Rating: 10mcd
• Viewing Angle: 40°
• Wavelength - Peak: 430nm
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 4.50mm

The primary distinction is product status: the 3BWD is obsolete, while the 3BWD-S is active, making it the direct replacement for new designs and continued production requirements.

Parameter Comparison

Engineering Selection Recommendations

The 3BWD-S is the appropriate selection for all new designs and production applications requiring a blue diffused T-1 LED indicator with 4V forward voltage and 10mcd intensity. The 3BWD-S maintains full electrical and mechanical compatibility with the obsolete 3BWD while offering active product status and continued manufacturing support from Bivar Inc. The 3BWD-S is RoHS3 compliant, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 3BWD-S be used as a direct replacement for the 3BWD? A: Yes. The 3BWD-S is electrically and mechanically identical to the 3BWD across all specified parameters, including forward voltage, current rating, light intensity, wavelength, viewing angle, lens configuration, and mounting type. Direct substitution is supported without circuit modification.

Q: What is the difference between the 3BWD and 3BWD-S? A: The 3BWD is obsolete, while the 3BWD-S is an active product from the same manufacturer. All electrical specifications, optical characteristics, and mechanical dimensions are identical. The primary difference is product lifecycle status and continued availability.

Q: Are there packaging differences between these parts? A: The 3BWD is supplied in standard packaging, while the 3BWD-S is supplied in bulk packaging. This difference does not affect electrical or mechanical performance and is a procurement consideration only.

Q: What compliance certifications apply to the substitute part? A: The 3BWD-S is RoHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components distributed in regulated markets.

Q: Is the 40° viewing angle suitable for all application types? A: The 40° viewing angle is a fixed specification for this lens style and applies to both the 3BWD and 3BWD-S. Application suitability depends on the specific requirement for optical beam spread and must be evaluated against the end-use design criteria.
