3BWD5V LED Blue Diffused T-1 Through-Hole Equivalent & Substitute Parts

Part Overview

The 3BWD5V is a blue diffused LED indicator manufactured by Bivar Inc., designed for discrete 5V radial applications in through-hole mounting configurations. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. The 3BWD5V provides blue light indication with a 10mcd brightness rating and 40° viewing angle in a compact 3mm T-1 package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3BWD5V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Blue
• Lens Transparency: Diffused
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Wavelength - Peak: 430nm
• Viewing Angle: 40°
• Height (Max): 4.50mm

Secondary Electrical Parameters:

• Voltage - Forward (Vf) Typical: 5V nominal operation
• Current - Test: 8mA nominal operation
• Millicandela Rating: 10mcd

The 3BWD-S qualifies as a parametric equivalent based on matching all primary compatibility criteria. Variations in forward voltage (4V vs. 5V) and test current (20mA vs. 8mA) reflect different operational specifications but do not preclude substitution in applications where circuit design accommodates the alternative electrical characteristics.

Engineering Selection Recommendations

The 3BWD-S is the identified substitute for the obsolete 3BWD5V. Selection between these parts is determined by application requirements and supply chain considerations:

3BWD5V Selection Criteria:

• Existing inventory availability: 1111 pieces in stock
• Legacy design support where 5V forward voltage specification is mandatory
• Applications requiring 8mA test current specification

3BWD-S Selection Criteria:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance certification for regulated markets and environmental standards
• Bulk packaging option for high-volume production requirements
• 4V forward voltage and 20mA test current specifications compatible with circuit designs accommodating these parameters
• Recommended for new designs and production transitions

Both parts share identical mechanical dimensions, optical characteristics, and mounting requirements, enabling direct footprint compatibility in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the 3BWD-S directly replace the 3BWD5V in existing designs?

A: Direct replacement requires circuit design verification. The 3BWD-S operates at 4V forward voltage versus the 3BWD5V's 5V specification. Current-limiting resistor values and power supply voltage must be evaluated to confirm compatibility with the 20mA test current of the 3BWD-S versus the 8mA specification of the 3BWD5V.

Q: Are the physical dimensions identical between 3BWD5V and 3BWD-S?

A: Yes. Both parts share identical mechanical specifications: 3mm T-1 lens size, 4.50mm maximum height, radial package configuration, and through-hole mounting type. PCB footprints are interchangeable.

Q: What is the significance of the product status difference?

A: The 3BWD5V is classified as obsolete, indicating discontinued manufacturing and limited future availability. The 3BWD-S maintains active product status, ensuring ongoing supply and manufacturing support. For new designs and long-term production, the 3BWD-S is the recommended selection.

Q: Do both parts meet environmental compliance requirements?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating. The 3BWD-S is certified ROHS3 compliant. The 3BWD5V compliance status is not specified in available documentation.

Q: What optical characteristics are shared between these parts?

A: Both parts provide identical optical performance: blue diffused lens, 10mcd brightness rating, 430nm peak wavelength, and 40° viewing angle. Optical appearance and light distribution are functionally equivalent.

Q: Are there packaging differences between these parts?

A: The 3BWD5V is supplied in standard packaging, while the 3BWD-S is available in bulk packaging. Bulk packaging is typically selected for high-volume production requirements and offers cost advantages for large-quantity orders.
