3SBCC-Y/G-F LED Equivalent and Substitute Parts

Part Overview

The 3SBCC-Y/G-F is a bidirectional through-hole LED from Bivar Inc. featuring green and yellow light output with a clear, domed 3mm lens. This discrete component provides dual-color indication capability with forward voltages of 2.1V (green) and 2V (yellow) at 20mA test current. The product is currently classified as obsolete, necessitating identification of functionally equivalent active alternatives for new designs and legacy system maintenance.

Substitute Part Grouping Explanation

The 3SBCC-Y/G-F can be substituted with the 3BC-Y/G-F based on the following critical parameters:

Matching Electrical Characteristics:

• Identical forward voltages (2.1V Green, 2V Yellow)
• Identical test current (20mA for both colors)
• Identical peak wavelengths (568nm Green, 590nm Yellow)
• Identical physical package and mounting configuration (radial through-hole)

Allowed Parameter Variations:

• Lens transparency: Clear (main part) to Diffused (substitute) — both acceptable for indication applications
• Millicandela rating: 15mcd/20mcd (main) to 6mcd/4mcd (substitute) — reduced brightness in substitute
• Viewing angle: 40° (main) to 45° (substitute) — minor increase in viewing angle
• Product status: Obsolete (main) to Active (substitute) — ensures continued sourcing capability

The 3BC-Y/G-F is an active production component with established supply chain availability and maintains full electrical compatibility with the original specification.

Engineering Selection Recommendations

The 3BC-Y/G-F is a direct electrical and mechanical substitute for the obsolete 3SBCC-Y/G-F. Selection of the 3BC-Y/G-F is justified by:

Supply Chain Continuity: The substitute is an active production part with established availability from Bivar Inc., ensuring long-term sourcing for production and service applications.

Compliance Status: The 3BC-Y/G-F carries ROHS3 compliance certification, meeting current regulatory requirements for manufactured components. This compliance status provides assurance for applications subject to RoHS directives.

Electrical Compatibility: Identical forward voltages and test currents ensure direct drop-in replacement without circuit redesign or current-limiting resistor modification.

Mechanical Interchangeability: Radial package configuration, identical physical dimensions (5.30mm maximum height), and T-1 lens size provide mechanical equivalence for PCB footprints and through-hole mounting applications.

Parameter Trade-offs: The reduced luminous intensity (6mcd/4mcd versus 15mcd/20mcd) and diffused lens characteristic shift the substitute toward status indication in higher ambient light conditions. Applications requiring the original clear, high-brightness characteristics should evaluate alternative sources or application-specific modified designs.

Frequently Asked Questions (FAQ)

Q: Can the 3BC-Y/G-F replace the 3SBCC-Y/G-F without circuit modification? A: Yes. Identical forward voltages (2.1V green, 2V yellow) and test current (20mA) eliminate the need for resistor or circuit redesign. Direct substitution is electrically valid.

Q: What is the primary difference between these two parts? A: The main differences are lens transparency (clear versus diffused) and luminous intensity (15mcd/20mcd versus 6mcd/4mcd). The substitute provides softer light distribution suitable for status indication at closer viewing distances. Applications requiring high-brightness, focused beam characteristics should evaluate alternative components.

Q: Why is the 3SBCC-Y/G-F classified as obsolete? A: Obsolescence is determined by manufacturer production discontinuation. The 3BC-Y/G-F remains in active production and is recommended for all new designs.

Q: Are both parts identical in physical dimensions? A: Yes. Both components have a maximum height of 5.30mm with radial package configuration and T-1 lens size, ensuring mechanical interchangeability in through-hole applications.

Q: Is the 3BC-Y/G-F RoHS compliant? A: Yes. The 3BC-Y/G-F is ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What viewing angle difference exists between these parts? A: The 3SBCC-Y/G-F provides a 40° viewing angle, while the 3BC-Y/G-F provides a 45° viewing angle. This minor difference reflects the diffused lens design of the substitute.

Q: Can the 3BC-Y/G-F be used in applications requiring high luminous intensity? A: The 3BC-Y/G-F produces lower luminous intensity (6mcd/4mcd) compared to the original (15mcd/20mcd). Applications with stringent brightness requirements should evaluate alternative high-brightness LED sources.
