Bivar Inc. 3BCC-Y/G LED Indicator - Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 3BCC-Y/G is a bidirectional LED indicator combining green and yellow light emission in a single 3mm through-hole package. This component provides discrete color indication with a clear lens for high-brightness applications. The main part is classified as obsolete, making identification of active substitute components essential for ongoing production support and design updates.

Key Parameters

Substitute Part Grouping Explanation

The primary substitute for the 3BCC-Y/G is the Bivar Inc. 3BC-Y/G. This substitution is valid based on the following critical matching parameters:

• Color and Configuration: Both parts provide identical green and yellow bidirectional LED indication
• Voltage Specifications: Forward voltage ratings are identical (2.1V Green, 2V Yellow)
• Optical Output: Both achieve 6mcd Green and 4mcd Yellow brightness
• Wavelength Characteristics: Peak wavelengths match exactly (568nm Green, 590nm Yellow)
• Package and Mounting: Both use 3mm T-1 through-hole radial packages
• Reliability Ratings: Both are MSL 1 (Unlimited) moisture sensitivity

The allowable differences between the main part and substitute are:

• Lens Transparency: Main part uses clear lens; substitute uses diffused lens (white color)
• Test Current: Main part rated at 30mA per color; substitute rated at 20mA per color
• Viewing Angle: Main part 40°; substitute 45°
• Maximum Height: Main part 5.30mm; substitute 4.50mm
• Product Status: Main part obsolete; substitute active with RoHS3 compliance

Engineering Selection Recommendations

Primary Recommendation: 3BC-Y/G

The 3BC-Y/G is the direct active substitute for the obsolete 3BCC-Y/G. This component maintains electrical compatibility through identical forward voltage and optical output specifications. The substitute is currently in active production status with RoHS3 compliance certification, ensuring regulatory adherence and supply chain continuity.

The lower test current specification (20mA vs. 30mA) in the substitute provides reduced power consumption while maintaining equivalent brightness output. The shorter maximum height (4.50mm vs. 5.30mm) may require PCB layout verification for existing designs. The diffused lens (vs. clear lens on the main part) alters light dispersion characteristics but maintains the specified viewing angle requirement at 45°.

For applications requiring the exact clear lens characteristic of the original 3BCC-Y/G, design verification is necessary to confirm the diffused lens variant meets operational requirements.

Frequently Asked Questions (FAQ)

Q1: Can the 3BC-Y/G replace the 3BCC-Y/G in all applications?

The 3BC-Y/G is electrically compatible with the 3BCC-Y/G for the same forward voltage range (2.1V Green, 2V Yellow) and brightness output (6mcd Green, 4mcd Yellow). The primary design consideration is the lens characteristic change from clear to diffused, which affects light dispersion. Mechanical height reduction (0.80mm) must be evaluated against PCB footprint constraints.

Q2: What is the difference between a clear and diffused lens?

The 3BCC-Y/G features a clear lens for concentrated, directional light output. The 3BC-Y/G uses a diffused (white) lens that scatters light over a wider area with more uniform intensity distribution. This accounts for the 45° vs. 40° viewing angle specifications.

Q3: Why does the 3BC-Y/G specify lower test current (20mA vs. 30mA)?

Both parts achieve identical brightness output (6mcd Green, 4mcd Yellow) at their respective test currents. The 3BC-Y/G achieves equivalent optical performance at reduced current, resulting in lower power consumption. This is a characteristic of LED manufacturing improvements and does not indicate reduced operational capacity.

Q4: Is the 3BC-Y/G RoHS compliant?

The 3BC-Y/G carries RoHS3 compliance certification. The original 3BCC-Y/G (obsolete status) compliance information is not specified in available documentation.

Q5: Are the radial through-hole packages identical between parts?

Both components use identical 3mm T-1 radial through-hole packages with round domed tops. The 0.80mm height difference reflects manufacturing design refinement but does not affect standard PCB mounting practices.
