Key Parameters

Substitute Part Grouping Explanation

The 3BC-3-R/Y-F qualifies as a functional substitute for the 3BCC-R/Y-F based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Lens size: 3mm, T-1 form factor
• Color configuration: Red and Yellow dual-color operation
• Forward voltage: 2V Red, 2V Yellow
• Peak wavelength: 625nm Red, 590nm Yellow
• Viewing angle: 40°
• Mounting type: Through-hole radial configuration
• Package type: Radial

Substitution Basis: The 3BC-3-R/Y-F maintains electrical compatibility through identical forward voltage specifications and wavelength characteristics. Both components operate within the same physical envelope (3mm T-1 package) and employ radial through-hole mounting. The substitute part is currently in active production status, addressing the obsolescence of the original 3BCC-R/Y-F.

Engineering Selection Recommendations

The 3BC-3-R/Y-F is the designated substitute for the obsolete 3BCC-R/Y-F. Selection of this alternative is based on the following engineering criteria:

Product Status Alignment: The substitute part is in active production, ensuring long-term availability and supply chain continuity. The original part's obsolete status creates procurement risk for new designs and ongoing production requirements.

Electrical Compatibility: Forward voltage specifications are identical (2V Red, 2V Yellow), enabling direct circuit integration without modification to current-limiting resistor calculations or power supply requirements. Peak wavelength values match exactly, maintaining color consistency in visual indication applications.

Mechanical Compatibility: Both components utilize the 3mm T-1 through-hole radial package, permitting direct PCB footprint compatibility. The substitute's maximum height of 7.00mm compared to the original 5.30mm requires verification of available vertical clearance in the target application.

Compliance Status: The 3BC-3-R/Y-F carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for component procurement in regulated industries.

Operational Differences: The substitute operates at reduced test current (20mA versus 30mA) while delivering increased light output (30mcd red, 20mcd yellow versus 8mcd red, 6mcd yellow). The diffused lens of the substitute provides broader light distribution compared to the clear lens of the original part. Configuration change from bidirectional to common cathode requires circuit topology verification.

Frequently Asked Questions (FAQ)

Q: Can the 3BC-3-R/Y-F directly replace the 3BCC-R/Y-F without circuit modification?

A: Electrical substitution is feasible due to matching forward voltage and wavelength specifications. However, the configuration change from bidirectional to common cathode requires verification of the circuit topology. The increased light output (30mcd/20mcd versus 8mcd/6mcd) may necessitate adjustment of current-limiting resistor values if the original design operated at maximum brightness. The reduced test current specification (20mA versus 30mA) permits lower power consumption in the substitute design.

Q: What are the physical compatibility considerations?

A: Both components share the 3mm T-1 through-hole radial package and identical lens diameter. The substitute's maximum height of 7.00mm exceeds the original 5.30mm by 1.70mm. PCB layout verification is required to confirm adequate clearance above the component. The diffused lens of the substitute produces a different light distribution pattern compared to the clear lens of the original part, potentially affecting visual indication characteristics in the application.

Q: Are there compliance or regulatory differences between these parts?

A: The 3BC-3-R/Y-F carries ROHS3 compliance certification. The original 3BCC-R/Y-F does not specify RoHS status. Both components carry identical MSL rating (1 - Unlimited) and ECCN/HTSUS classifications, indicating equivalent handling and regulatory treatment for export and import purposes.

Q: What is the difference between bidirectional and common cathode configuration?

A: The original 3BCC-R/Y-F operates in bidirectional mode, allowing independent control of red and yellow LEDs with separate anode and cathode connections. The 3BC-3-R/Y-F uses common cathode configuration, where both LEDs share a single cathode connection and require individual anode connections for independent color control. Circuit redesign is necessary if the original design relied on bidirectional operation characteristics.

Q: How does the lens transparency difference affect application performance?

A: The original part features a clear lens providing focused, directional light output. The substitute employs a diffused lens that scatters light over a broader area. This difference impacts viewing angle characteristics and brightness perception at various observation angles. Applications requiring concentrated light output in a specific direction may experience performance changes with the diffused lens substitute.
