Equivalent & Substitute Parts for R5GDL

Part Overview

The R5GDL is a green LED indication component manufactured by Bivar Inc., designed for through-hole mounting applications. This discrete 2.1V radial LED features a diffused rectangular lens with a 4.90mm x 1.90mm lens size and operates at 2mA test current with a 120° viewing angle. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the R5GDL is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) must be 2.1V to maintain circuit design integrity
• Mounting type must be through-hole radial configuration
• Package classification must be radial

Optical Compatibility:

• Color must be green
• Lens transparency must be diffused
• Lens style must be rectangular with flat top
• Wavelength range must align with green spectrum (560-570nm peak)

Mechanical Compatibility:

• Lens dimensions and height must accommodate existing PCB layouts
• Viewing angle of 120° or greater ensures equivalent light distribution

The substitute part 5219332F from Dialight meets these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 5219332F from Dialight is a qualified substitute for the obsolete R5GDL. Both components share identical forward voltage (2.1V), matching wavelength specifications (568nm vs 565nm peak), and equivalent moisture sensitivity ratings. The substitute maintains through-hole radial mounting compatibility with diffused green rectangular lens configuration.

The 5219332F offers active product status with ROHS3 compliance and REACH unaffected designation, providing long-term supply chain stability. Lens dimensions are marginally larger (5.00mm x 2.00mm versus 4.90mm x 1.90mm), and maximum height increases by 0.50mm (7.50mm versus 7.00mm). These dimensional variations are within typical PCB layout tolerances for through-hole LED applications.

The test current specification differs (10mA for 5219332F versus 2mA for R5GDL); however, this parameter reflects manufacturer test conditions and does not restrict circuit-level substitution when forward voltage and optical characteristics are maintained.

Frequently Asked Questions (FAQ)

Q: Can the 5219332F directly replace the R5GDL in existing designs?

A: Yes, the 5219332F is electrically and optically compatible. Both components operate at 2.1V forward voltage with matching green diffused rectangular lens configuration and radial through-hole mounting. Verify PCB layout accommodates the slightly larger lens dimensions (5.00mm x 2.00mm) and 0.50mm additional height.

Q: What is the significance of the different test current ratings (2mA vs 10mA)?

A: Test current is a manufacturer specification used for characterization and does not restrict substitution. Circuit design should be based on forward voltage (2.1V for both) and desired operating current, which is independently determined by series resistor selection.

Q: Are there compliance differences between the two parts?

A: The 5219332F provides ROHS3 compliance and REACH unaffected status, offering regulatory advantages over the obsolete R5GDL. Both components share identical MSL rating of 1 (Unlimited) and EAR99 export classification.

Q: How do the viewing angles compare?

A: The R5GDL specifies 120° viewing angle while the 5219332F provides 140°. The wider viewing angle of the substitute ensures equivalent or improved light distribution in indication applications.

Q: What packaging considerations apply to the 5219332F?

A: The 5219332F is supplied in bulk packaging. Lens size is 5.00mm x 2.00mm (rectangular), and maximum height is 7.50mm. Confirm PCB footprint and component clearance accommodate these dimensions before procurement.
