Substitute Part Grouping Explanation

Substitution of the obsolete 3SBC-Y/G-F is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 2.1V Green, 2V Yellow
• Test current: 20mA Green, 20mA Yellow
• Wavelength - Peak: 568nm Green, 590nm Yellow

Mechanical Compatibility:

• Lens size: 3mm, T-1
• Mounting type: Through Hole
• Package configuration: Radial
• Height (Max): 5.30mm
• Lens transparency: Diffused

Functional Compatibility:

• Color: Green, Yellow
• Configuration: Bidirectional
• Viewing angle: 45°

The substitute part 3BC-Y/G-F maintains electrical and mechanical equivalence across all critical parameters. Differences in millicandela rating (6mcd Green, 4mcd Yellow versus 15mcd Green, 20mcd Yellow) represent a reduction in luminous intensity and must be evaluated against specific application brightness requirements.

Engineering Selection Recommendations

The 3BC-Y/G-F serves as the active equivalent for the obsolete 3SBC-Y/G-F. Selection of this substitute is based on:

Electrical Equivalence: Forward voltage and test current specifications are identical, ensuring direct circuit compatibility without modification to drive circuitry or current-limiting resistor calculations.

Mechanical Equivalence: Through-hole radial package configuration, T-1 lens size, and maximum height are identical, permitting direct PCB footprint compatibility and mechanical fit within existing enclosures.

Functional Equivalence: Bidirectional configuration, dual-color capability, diffused lens transparency, and viewing angle are maintained, preserving the intended indication functionality.

Compliance Status: The substitute part carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and procurement.

Luminous Intensity Consideration: The substitute exhibits reduced millicandela ratings (6mcd Green, 4mcd Yellow versus 15mcd Green, 20mcd Yellow). Applications requiring the original brightness specification must evaluate whether the reduced intensity remains acceptable for the intended indication function and viewing distance.

Frequently Asked Questions (FAQ)

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

A: Yes. Electrical parameters including forward voltage (2.1V Green, 2V Yellow) and test current (20mA) are identical. Existing current-limiting resistor values and drive circuit configurations remain valid.

Q: What is the primary difference between these parts?

A: The 3BC-Y/G-F has reduced luminous intensity (6mcd Green, 4mcd Yellow) compared to the original 3SBC-Y/G-F (15mcd Green, 20mcd Yellow). All other electrical, mechanical, and functional parameters are equivalent.

Q: Is the 3BC-Y/G-F suitable for applications requiring high brightness indication?

A: The reduced millicandela rating must be evaluated against specific application requirements. Applications with extended viewing distances or high ambient light conditions may require brightness assessment.

Q: Are the through-hole mounting footprints identical?

A: Yes. Both parts use radial through-hole configuration with T-1 (3mm) lens size and 5.30mm maximum height, permitting direct PCB footprint compatibility.

Q: Does the substitute part meet current environmental standards?

A: Yes. The 3BC-Y/G-F carries ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Q: What is the packaging difference between these parts?

A: The main part (3SBC-Y/G-F) is listed with packaging designation "-" while the substitute (3BC-Y/G-F) is supplied in Bulk packaging. This affects procurement and handling but does not impact component functionality or performance.

Q: Are the optical characteristics identical?

A: Yes. Both parts feature diffused lens transparency, white lens color, 45° viewing angle, and identical peak wavelengths (568nm Green, 590nm Yellow).
