5SBC LED Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5SBC is a bidirectional LED indicator in 5mm T-1 3/4 through-hole packaging, providing both green and red indication capability with diffused lens optics. The 5SBC operates at 2.2V forward voltage for green and 1.7V for red, delivering 50mcd and 100mcd brightness respectively at 20mA test current. This product is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility within equivalent electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5SBC is determined by the following critical parameters that must be maintained or exceeded for functional equivalence:

Mechanical Compatibility:

• Lens size: 5mm T-1 3/4 package
• Mounting type: Through-hole radial configuration
• Lens style: Round with domed top
• Maximum height: Comparable to original specification (8.80mm)

Electrical Compatibility:

• Bidirectional configuration (dual-color green/red operation)
• Forward voltage tolerance: Green operating range 2.1V–2.2V; Red operating range 1.7V–2.0V
• Test current: 20mA for both colors
• Viewing angle: 45° minimum

Optical Performance:

• Lens transparency: Diffused
• Wavelength compatibility: Green 568nm reference; Red 625nm–650nm range
• Brightness rating: Minimum specifications defined by millicandela ratings

The 5BC variant from Bivar Inc. satisfies these substitution criteria while offering active product status and current availability.

Engineering Selection Recommendations

5BC as Primary Substitute for 5SBC:

The 5BC is the direct substitute for obsolete 5SBC applications. Both components are manufactured by Bivar Inc. and share identical mechanical form factor (5mm T-1 3/4 through-hole radial package) and electrical configuration (bidirectional operation, 20mA test current, 45° viewing angle, diffused lens optics).

Product Status Consideration: The 5SBC is classified as obsolete with no current production. The 5BC maintains active production status, ensuring long-term supply chain availability and design continuity for new builds and field replacements.

Compliance Status: The 5BC is ROHS3 compliant, satisfying current environmental and regulatory requirements. Compliance information for the 5SBC is not specified in available documentation.

Brightness Performance Trade-Off: The 5BC operates at reduced brightness ratings compared to the 5SBC (8mcd green vs. 50mcd green; 6mcd red vs. 100mcd red). Applications requiring the original brightness specification should evaluate circuit designs for compensating brightness deficiency through increased operating current or optical design modifications.

Electrical Tolerance: Forward voltage specifications for the 5BC (2.1V green, 2.0V red) remain within acceptable tolerance ranges of typical LED indicator circuit designs. The 5BC red forward voltage of 2.0V represents a 0.3V increase from the 5SBC specification of 1.7V, requiring circuit validation in low-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can the 5BC be directly substituted for 5SBC in existing circuit designs? A: The 5BC is mechanically and electrically compatible for through-hole PCB mounting and bidirectional color operation. However, circuit designs relying on the original 5SBC brightness specification (50mcd green, 100mcd red) require performance reassessment. The 5BC operates at significantly lower brightness (8mcd green, 6mcd red) and may not meet applications demanding high visibility indicator operation.

Q: What are the primary differences between 5SBC and 5BC? A: Primary differences are product status (5SBC is obsolete; 5BC is active), brightness rating (5SBC is brighter), red wavelength (5SBC 650nm; 5BC 625nm), and RoHS compliance (5BC is ROHS3 compliant). Both share identical 5mm T-1 3/4 package geometry and electrical test current (20mA).

Q: Are there any package compatibility issues with 5BC substitution? A: No. The 5BC maintains the same 5mm T-1 3/4 through-hole radial package as the 5SBC. The 5BC maximum height of 8.50mm is slightly shorter than the 5SBC specification of 8.80mm, presenting no mechanical interference issues for standard through-hole mounting.

Q: How do I address the brightness difference between 5SBC and 5BC in my application? A: Brightness differences are determined by LED chip specification and cannot be altered by circuit design. If the lower brightness of the 5BC is unacceptable, alternative LED indicators from other manufacturers meeting the original 5SBC brightness specification (50mcd+ green, 100mcd+ red) in 5mm T-1 3/4 package must be evaluated.

Q: Is the forward voltage difference critical for my design? A: The 5BC forward voltage for red (2.0V) differs from the 5SBC specification (1.7V) by 0.3V. This difference is significant only in low-voltage applications operating near the minimum voltage threshold. Standard indicator circuit designs (typically 5V or higher supply voltage) accommodate this tolerance without modification.

Q: Does the 5BC meet current regulatory requirements? A: Yes. The 5BC is ROHS3 compliant, satisfying current environmental regulations for electronic component manufacturing and distribution.
