Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5SBC-3-F is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Dual-color configuration (Green and Red)
• Common cathode electrical configuration
• Through-hole mounting type
• 5mm T-1 3/4 package form factor
• Forward voltage ranges: Green 2.1V–2.2V, Red 1.7V–2.0V
• Test current specification: 20mA per color
• Wavelength compatibility: Green 568nm, Red 625nm–660nm

Allowable Variation Parameters:

• Lens transparency (clear to diffused)
• Millicandela rating (brightness variation acceptable based on application requirements)
• Viewing angle (20° to 40°)
• Physical height (8.60mm to 10.11mm)
• Lens color (clear to white diffused)

The substitute part 5BC-3-F meets the mandatory compatibility criteria while introducing controlled variations in lens properties and brightness characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5BC-3-F

The 5BC-3-F from Bivar Inc. is the direct substitute for the obsolete 5SBC-3-F. Both components share identical manufacturer lineage, electrical configuration, and package specifications. The 5BC-3-F maintains active product status, ensuring continued availability and supply chain reliability.

Electrical Compatibility: Forward voltage specifications for the 5BC-3-F fall within acceptable operating ranges relative to the 5SBC-3-F. Green forward voltage decreases from 2.2V to 2.1V, and red forward voltage increases from 1.7V to 2.0V. Both variations remain within standard LED operating tolerances for 20mA test current applications.

Optical Considerations: The 5BC-3-F introduces a diffused lens with white coloration, contrasting the clear lens of the 5SBC-3-F. This change reduces brightness output (35mcd versus 220mcd green, 35mcd versus 400mcd red) while expanding viewing angle from 20° to 40°. Selection between these parts depends on application-specific brightness and viewing angle requirements.

Compliance Status: The 5BC-3-F carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment compared to the obsolete 5SBC-3-F. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating.

Physical Integration: The 5BC-3-F exhibits reduced maximum height (8.60mm versus 10.11mm), allowing for tighter PCB layout constraints. Through-hole mounting compatibility remains unchanged, supporting direct board-level substitution without mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the 5BC-3-F directly replace the 5SBC-3-F in existing designs?

A: Electrical and mechanical compatibility is confirmed for through-hole PCB applications. The primary design consideration involves optical properties: the 5BC-3-F provides lower brightness (35mcd versus 220mcd/400mcd) with wider viewing angle (40° versus 20°) and diffused lens versus clear lens. Circuit designs relying on specific brightness levels require brightness compensation analysis.

Q: What are the forward voltage differences between these parts?

A: The 5SBC-3-F operates at 2.2V green and 1.7V red. The 5BC-3-F operates at 2.1V green and 2.0V red. These differences fall within standard LED operating tolerances and do not require circuit redesign for 20mA current-limited applications.

Q: Does the diffused lens of the 5BC-3-F affect circuit operation?

A: Lens transparency affects light distribution and perceived brightness but does not alter electrical operation. The diffused lens provides wider light distribution (40° viewing angle) compared to the clear lens (20° viewing angle). Application requirements determine whether this optical change is acceptable.

Q: Are there lead count differences between these parts?

A: The 5SBC-3-F and 5BC-3-F both feature radial configuration with common cathode connection. The 5BC-3-F is specified as 3-lead radial package, maintaining compatibility with existing through-hole PCB designs.

Q: What compliance certifications apply to the substitute part?

A: The 5BC-3-F carries ROHS3 compliance certification. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 export classification.

Q: Is the reduced height of the 5BC-3-F (8.60mm versus 10.11mm) a concern?

A: The reduced height provides design flexibility for compact PCB layouts. Through-hole mounting compatibility remains unchanged. Verify that reduced height does not conflict with mechanical clearance requirements in the specific application.

Q: What inventory status should be considered for procurement?

A: The 5SBC-3-F is classified as obsolete with 788 pieces in current stock. The 5BC-3-F maintains active product status with 935 pieces in inventory, supporting long-term supply chain continuity.
