Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 3BCC-3-F is determined by the following critical parameters:

Mechanical Compatibility:

• Package configuration: Radial - 3 Leads
• Lens size: T-1 (3mm)
• Mounting type: Through Hole
• Physical height: 5.30mm maximum
• Lens style: Round with Domed Top

Electrical Compatibility:

• Configuration: Common Cathode
• Color combination: Green and Red
• Forward voltage ranges: Green 2.1V–2.2V, Red 2.0V
• Test current capability: 20mA–30mA per color

Optical Characteristics:

• Wavelength compatibility: Green 568nm, Red 625nm–640nm
• Brightness range: 30mcd–70mcd per color

The substitute part 3BC-3-F maintains identical mechanical and electrical interface requirements while offering variations in lens transparency and brightness characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 3BC-3-F serves as a direct substitute for the obsolete 3BCC-3-F based on identical mechanical interface, electrical configuration, and package specifications. Both parts are manufactured by Bivar Inc. and share the same T-1 radial lead through-hole package with common cathode configuration.

Key Considerations:

The 3BC-3-F is classified as Active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete 3BCC-3-F. Both parts comply with identical regulatory classifications (EAR99, HTSUS 8541.41.0000) and moisture sensitivity levels (MSL 1).

The 3BC-3-F incorporates a diffused white lens versus the clear colorless lens of the 3BCC-3-F, resulting in optical characteristic differences. The substitute exhibits reduced brightness (30mcd versus 70mcd per color) and a wider viewing angle (40° versus 30°). Forward voltage specifications remain compatible within typical operating ranges (Green 2.1V–2.2V, Red 2.0V), and test current requirements are reduced (20mA versus 30mA per color).

The 3BC-3-F is available in bulk packaging with significantly higher inventory levels (2,885 pieces) compared to the 3BCC-3-F (815 pieces). The substitute part carries RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3BC-3-F replace the 3BCC-3-F in existing PCB designs without modification?

A: Yes. Both parts share identical mechanical interfaces (T-1 radial 3-lead package), electrical configuration (common cathode), and physical dimensions (5.30mm height). PCB footprints and lead spacing are compatible. No circuit board redesign is required.

Q: What are the optical differences between these two parts?

A: The 3BCC-3-F features a clear colorless lens with 70mcd brightness and 30° viewing angle. The 3BC-3-F features a diffused white lens with 30mcd brightness and 40° viewing angle. The diffused lens provides wider light distribution at reduced intensity.

Q: Are the forward voltage specifications compatible?

A: Yes. The 3BCC-3-F operates at 2.2V (green) and 2.0V (red). The 3BC-3-F operates at 2.1V (green) and 2.0V (red). These values are compatible within standard LED circuit design tolerances. Existing current-limiting resistor calculations remain valid.

Q: What is the impact of reduced test current (20mA versus 30mA)?

A: The 3BC-3-F operates at lower test current specifications, indicating reduced power consumption at rated brightness. Existing circuits designed for 30mA operation will function with the 3BC-3-F at reduced brightness levels. Circuit redesign is not required for compatibility.

Q: Does the substitute part meet current environmental compliance standards?

A: Yes. The 3BC-3-F carries RoHS3 compliance and REACH unaffected status. The original 3BCC-3-F (obsolete) does not specify these certifications. The substitute meets current regulatory requirements for new designs and production.

Q: What is the wavelength compatibility between these parts?

A: Green wavelength is identical (568nm). Red wavelength differs slightly (640nm for 3BCC-3-F versus 625nm for 3BC-3-F). Both values fall within the standard red LED spectrum range and are compatible for indicator applications.

Q: Is the 3BC-3-F available in the same packaging format?

A: The 3BC-3-F is supplied in bulk packaging, while the 3BCC-3-F was supplied in standard packaging. Both use identical component packaging (T-1 radial 3-lead). Bulk packaging affects order quantities and handling, not component compatibility.
