Bivar Inc. 5SGT LED Green Clear T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5SGT is a green LED indicator with clear lens transparency, designed for through-hole mounting applications. This component features a 5mm T-1 3/4 form factor with 50mcd brightness rating and 2.1V forward voltage. The product is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 5SGT are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Mounting Type: Through Hole (radial configuration)
• Lens Size: 5mm, T-1 3/4 form factor
• Voltage - Forward (Vf): 2.0V to 2.1V range
• Current - Test: 20mA
• Package / Case: Radial
• Moisture Sensitivity Level: MSL 1

Secondary Compatibility Considerations:

• Color family: Green or Yellow-Green wavelength range (568nm to 575nm)
• Lens Transparency: Clear or Diffused
• Millicandela Rating: 25mcd to 80mcd
• Viewing Angle: 30° to 45°
• Height (Max): 8.50mm to 8.90mm

The 5SGT has two identified substitutes: Bivar Inc. 5GD and Everlight Electronics Co Ltd 333-2SYGD/S530-E2. Both maintain core electrical parameters and through-hole radial mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Bivar Inc. 5GD Substitute:

The 5GD is an active product from the same manufacturer (Bivar Inc.) and maintains identical electrical specifications (2.1V Vf, 20mA test current) and mechanical form factor (5mm T-1 3/4, 8.50mm height). The primary difference is lens transparency: the 5GD features diffused lens versus the 5SGT clear lens, resulting in lower brightness (25mcd versus 50mcd) but wider viewing angle (45° versus 35°). Both components share identical wavelength-peak (568nm) and MSL rating. The 5GD is suitable for applications where diffused light output and wider viewing angle are acceptable trade-offs for active product availability.

Everlight Electronics Co Ltd 333-2SYGD/S530-E2 Substitute:

The 333-2SYGD/S530-E2 is an active product with compatible electrical parameters (2V Vf, 20mA test current) and through-hole radial mounting. This component features yellow-green color (573nm dominant, 575nm peak wavelength) with diffused lens and higher brightness (80mcd). The viewing angle is narrower (30° versus 35°), and maximum height is slightly greater (8.90mm versus 8.50mm). Both substitute components carry ROHS3 compliance certification. Selection of the 333-2SYGD/S530-E2 is appropriate for applications requiring higher brightness output and accepting yellow-green color shift and narrower viewing angle.

Selection Basis:

Both substitutes are active products with established supply availability. The choice between 5GD and 333-2SYGD/S530-E2 depends on application requirements regarding color (pure green versus yellow-green), brightness level (25mcd, 50mcd, or 80mcd), and viewing angle (30°, 35°, or 45°). Both maintain core electrical compatibility and through-hole radial mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the 5GD directly replace the 5SGT in all applications?

A: The 5GD maintains identical electrical specifications (2.1V Vf, 20mA) and mechanical form factor (5mm T-1 3/4 through-hole radial). The primary difference is lens transparency: diffused versus clear. Applications requiring clear lens and 50mcd brightness will experience reduced brightness (25mcd) and altered light distribution with the 5GD. Verify application tolerance for these optical characteristics before substitution.

Q: What is the color difference between the 5SGT and 333-2SYGD/S530-E2?

A: The 5SGT emits pure green light at 568nm peak wavelength. The 333-2SYGD/S530-E2 emits yellow-green light at 575nm peak wavelength with 573nm dominant wavelength. This represents a visible color shift toward yellow. Applications with color-specific requirements must account for this difference.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the Bivar Inc. 5GD and Everlight Electronics Co Ltd 333-2SYGD/S530-E2 carry ROHS3 compliance certification. The original 5SGT RoHS status is not specified in available documentation.

Q: What is the brightness difference between the three parts?

A: The 5SGT provides 50mcd brightness. The 5GD provides 25mcd (50% reduction). The 333-2SYGD/S530-E2 provides 80mcd (60% increase). Application light output requirements determine which brightness level is appropriate.

Q: Do all three parts use the same mounting configuration?

A: Yes. All three components use through-hole radial mounting with 5mm lens diameter and T-1 3/4 form factor. Maximum heights are 8.50mm (5SGT and 5GD) and 8.90mm (333-2SYGD/S530-E2). PCB hole spacing and lead diameter compatibility should be verified for the specific application.

Q: What is the viewing angle difference?

A: The 5SGT has 35° viewing angle. The 5GD has 45° (wider). The 333-2SYGD/S530-E2 has 30° (narrower). Viewing angle affects the cone of light visibility. Applications with specific directional light requirements must account for these differences.

Q: Can the 333-2SYGD/S530-E2 be used where the 5SGT is specified?

A: The 333-2SYGD/S530-E2 maintains compatible electrical parameters (2V Vf versus 2.1V, within tolerance) and through-hole radial mounting. However, it differs in color (yellow-green versus green), brightness (80mcd versus 50mcd), viewing angle (30° versus 35°), and height (8.90mm versus 8.50mm). Substitution is valid only if the application accepts these optical and mechanical variations.
