Equivalent & Substitute Parts for 5BWT Blue LED T-1 3/4 Through Hole

Part Overview

The 5BWT is a blue LED indicator manufactured by Bivar Inc., designed for discrete 4V radial applications in through-hole mounting configurations. This component features a clear lens with 30mcd brightness rating and a 20° viewing angle, suitable for standard indication applications requiring high luminous intensity.

The 5BWT is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5BWT is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Bivar Inc.
• Color: Blue
• Lens Size: 5mm, T-1 3/4
• Voltage - Forward (Vf): 4V
• Current - Test: 20mA
• Mounting Type: Through Hole
• Package / Case: Radial
• Wavelength - Peak: 430nm
• Height (Max): 8.50mm

Allowable Variation Parameters:

• Lens Transparency (Clear vs. Diffused)
• Millicandela Rating (brightness intensity)
• Viewing Angle
• Product Status (Obsolete vs. Active)

The 5BWD qualifies as a substitute because it maintains all mandatory electrical and mechanical parameters while varying only in lens transparency and optical characteristics, which are application-dependent selections rather than compatibility constraints.

Parameter Comparison

Engineering Selection Recommendations

5BWT Selection Criteria: The 5BWT is suitable for applications requiring a clear lens with narrow 20° viewing angle and maximum brightness intensity of 30mcd. This configuration is appropriate for focused indication applications where high luminous intensity and directional light output are required. However, the obsolete status limits long-term availability.

5BWD Selection Criteria: The 5BWD is the active substitute part from Bivar Inc. It maintains identical electrical specifications (4V forward voltage, 20mA test current) and mechanical compatibility (T-1 3/4 through-hole radial package, 8.50mm height). The 5BWD features a diffused lens reducing brightness to 15mcd with an expanded 45° viewing angle, suitable for applications requiring wider light distribution. The active product status ensures ongoing supply chain availability and RoHS3 compliance certification.

Substitution Feasibility: Direct substitution of 5BWD for 5BWT is electrically and mechanically compatible. Selection between these parts depends on optical requirements: choose 5BWT for narrow-angle high-intensity indication, or 5BWD for wide-angle diffused indication. The 5BWD is recommended for new designs due to active product status.

Frequently Asked Questions (FAQ)

Q: Can the 5BWD directly replace the 5BWT in existing designs?

A: Electrical and mechanical compatibility is confirmed. Both parts share identical forward voltage (4V), test current (20mA), mounting type (through-hole radial), and physical dimensions (5mm T-1 3/4, 8.50mm height). Substitution feasibility depends on optical requirements. The 5BWD's diffused lens and 45° viewing angle differ from the 5BWT's clear lens and 20° viewing angle. Verify that the application tolerates reduced brightness (15mcd vs. 30mcd) and wider light distribution before substitution.

Q: Why does the 5BWD have lower brightness than the 5BWT?

A: The brightness difference (15mcd vs. 30mcd) results from the diffused lens design of the 5BWD. Diffusion spreads light across a wider viewing angle (45° vs. 20°), reducing peak intensity while improving visibility across a broader field of view. This is a design trade-off, not a deficiency.

Q: Are both parts RoHS compliant?

A: The 5BWD is certified RoHS3 compliant. The 5BWT specifications do not include RoHS certification data in the provided parameters. Verify RoHS compliance requirements for your application before final part selection.

Q: What is the packaging difference between these parts?

A: The 5BWT is supplied in standard packaging. The 5BWD is supplied in bulk packaging. Both use identical radial through-hole package configuration (T-1 3/4). Packaging format does not affect electrical or mechanical compatibility.

Q: Are there inventory considerations for these parts?

A: The 5BWT has 905 pieces in stock (obsolete status). The 5BWD has 898 pieces in stock (active status). For long-term supply assurance, the 5BWD is preferred due to its active product classification, which indicates ongoing manufacturing and availability.
