Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3BCC-Y/G-F is determined by the following critical parameters:

Mandatory Matching Criteria:

• Lens size: 3mm, T-1
• Mounting type: Through hole radial configuration
• Color capability: Green and yellow dual-color operation
• Configuration: Bidirectional
• Forward voltage: 2.1V green, 2V yellow
• Wavelength peaks: 568nm green, 590nm yellow
• Package type: Radial
• Height: 5.30mm maximum

Allowable Variation Parameters:

• Lens transparency (clear vs. diffused)
• Millicandela rating (brightness)
• Test current (within component design limits)
• Viewing angle (within optical design tolerance)
• Product status (active substitutes acceptable for obsolete parts)

The 3BC-Y/G-F qualifies as a direct substitute based on matching all mandatory criteria while offering active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3BC-Y/G-F serves as the direct equivalent for the obsolete 3BCC-Y/G-F. Selection of this substitute is supported by the following engineering factors:

Product Status Consideration: The 3BC-Y/G-F maintains active product status with Bivar Inc., ensuring continued availability and manufacturing support compared to the obsolete 3BCC-Y/G-F.

Compliance Certification: The 3BC-Y/G-F carries RoHS3 compliance certification, meeting current environmental and regulatory requirements for electronic component procurement.

Electrical Compatibility: Both components share identical forward voltage specifications (2.1V green, 2V yellow) and wavelength peaks (568nm green, 590nm yellow), ensuring circuit-level compatibility without modification.

Mechanical Compatibility: Identical lens size (3mm T-1), mounting configuration (through-hole radial), and maximum height (5.30mm) confirm direct PCB footprint compatibility.

Optical Consideration: The 3BC-Y/G-F features diffused lens transparency versus the clear lens of the 3BCC-Y/G-F, resulting in reduced brightness (6mcd green, 4mcd yellow versus 8mcd green, 6mcd yellow) but increased viewing angle (45° versus 40°). This trade-off is acceptable for applications where uniform light distribution is preferred over peak brightness.

Current Rating Adjustment: The 3BC-Y/G-F operates at 20mA test current compared to 30mA for the 3BCC-Y/G-F, representing a 33% reduction in power consumption while maintaining functional light output through the diffused lens design.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical lens size (3mm T-1), through-hole radial mounting configuration, and maximum height (5.30mm), confirming direct PCB footprint compatibility without layout changes.

Q: What is the primary optical difference between these two components?

A: The 3BCC-Y/G-F features a clear lens providing focused light output at 40° viewing angle with higher brightness (8mcd green, 6mcd yellow). The 3BC-Y/G-F features a diffused lens providing dispersed light output at 45° viewing angle with lower brightness (6mcd green, 4mcd yellow). Selection depends on application requirements for light concentration versus distribution.

Q: Are the electrical specifications identical between these components?

A: Forward voltage and wavelength specifications are identical (2.1V green at 568nm, 2V yellow at 590nm). Test current differs: 3BCC-Y/G-F operates at 30mA while 3BC-Y/G-F operates at 20mA. This difference reflects the optical design variation and does not affect circuit compatibility.

Q: Why is the 3BC-Y/G-F recommended over the obsolete 3BCC-Y/G-F?

A: The 3BC-Y/G-F maintains active product status with Bivar Inc., ensuring ongoing manufacturing support and availability. It also carries RoHS3 compliance certification, meeting current regulatory requirements. Electrical and mechanical compatibility is confirmed.

Q: What packaging options are available for the 3BC-Y/G-F?

A: The 3BC-Y/G-F is supplied in bulk packaging, suitable for production assembly operations. The component maintains the same radial package configuration as the 3BCC-Y/G-F.

Q: Is the increased viewing angle of the 3BC-Y/G-F (45° vs 40°) significant for substitution?

A: The 5° increase in viewing angle results from the diffused lens design and represents an improvement in light distribution uniformity. This is beneficial for applications requiring wider light visibility and does not create compatibility issues.

Q: What is the moisture sensitivity level for both components?

A: Both the 3BCC-Y/G-F and 3BC-Y/G-F carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
