R7BWD LED Blue Diffused Through-Hole Equivalent & Substitute Parts

Part Overview

The R7BWD is a blue LED indication component manufactured by Bivar Inc., designed for discrete 4V radial applications. This through-hole mounted LED features a diffused rectangular lens with a 7.00mm x 2.40mm form factor and operates at a forward voltage of 4V with a 20mA test current. The product is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R7BWD are identified based on mechanical and electrical compatibility within the Bivar Inc. product line. The primary substitution criteria are:

Mechanical Compatibility Parameters:

• Identical lens style (Rectangle with Flat Top)
• Identical lens size (7.00mm x 2.40mm)
• Identical maximum height (7.70mm)
• Identical mounting type (Through Hole)
• Identical package configuration (Radial)

Electrical Compatibility Parameters:

• Identical test current (20mA)
• Identical viewing angle (120°)
• Identical moisture sensitivity level (MSL 1 - Unlimited)

Regulatory Compliance Parameters:

• Identical ECCN classification (EAR99)
• Identical HTSUS code (8541.41.0000)

The R7GD substitute part maintains full mechanical and regulatory alignment with the R7BWD while differing in color (green vs. blue), forward voltage (2.1V vs. 4V), millicandela rating (8mcd vs. 4mcd), and peak wavelength (568nm vs. 430nm). These differences reflect the inherent characteristics of different LED color technologies within the same mechanical platform.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The R7BWD is classified as obsolete. The R7GD substitute is classified as active product status, ensuring ongoing availability and manufacturing support from Bivar Inc.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent export control and tariff treatment. The R7GD provides additional RoHS3 compliance documentation, which may be required for certain applications or markets.

Mechanical Interchangeability: The R7GD maintains identical mechanical specifications across all critical dimensions and mounting parameters, enabling direct physical substitution in through-hole PCB applications without layout modifications.

Electrical Differences: Selection between R7BWD and R7GD requires circuit-level evaluation due to differences in forward voltage (4V vs. 2.1V) and millicandela rating (4mcd vs. 8mcd). These parameters directly affect current-limiting resistor values and visual brightness in the application circuit. Color difference (blue vs. green) is a functional requirement that must align with system design intent.

Frequently Asked Questions (FAQ)

Q: Can R7GD directly replace R7BWD in all applications?

A: R7GD maintains identical mechanical and mounting characteristics, enabling physical substitution. However, electrical circuit parameters require evaluation. The R7GD operates at 2.1V forward voltage compared to R7BWD's 4V, necessitating recalculation of series resistor values to maintain proper current limiting. Additionally, the color difference (green vs. blue) must align with application requirements.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical lens dimensions (7.00mm x 2.40mm), lens style (Rectangle with Flat Top), maximum height (7.70mm), mounting type (Through Hole), and radial package configuration. These parameters ensure identical PCB footprint and physical fit.

Q: How do the electrical specifications differ?

A: The R7GD operates at 2.1V forward voltage with 8mcd brightness, while the R7BWD operates at 4V with 4mcd brightness. Both use identical 20mA test current and 120° viewing angle. Circuit design must account for the voltage difference when selecting current-limiting resistors.

Q: Is the R7GD RoHS compliant?

A: The R7GD is documented as ROHS3 compliant. RoHS status for the R7BWD is not specified in available documentation.

Q: Are there inventory considerations?

A: The R7BWD is obsolete with 725 pieces in stock. The R7GD is active product with 664 pieces in stock, providing ongoing availability assurance.

Q: What regulatory classifications apply to both parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent export control and tariff treatment.
