Equivalent & Substitute Parts for 3SBC-F

Part Overview

The 3SBC-F is a bidirectional LED indicator manufactured by Bivar Inc., featuring integrated green and red light-emitting elements in a 3mm through-hole package. This component provides dual-color indication capability with diffused lens optics, delivering 8mcd green and 12mcd red output at standard test currents of 20mA per color.

The 3SBC-F is classified as obsolete. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3SBC-F are identified based on strict parameter matching within the following categories:

Critical Matching Parameters:

• Manufacturer: Bivar Inc.
• Color Configuration: Green and Red
• Mounting Type: Through Hole
• Lens Size: 3mm, T-1
• Forward Voltage (Vf): 2.1V Green, 1.7V Red
• Test Current: 20mA Green, 20mA Red
• Wavelength - Peak: 568nm Green, 645nm Red
• Package / Case: Radial
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Product Status: Active substitutes are acceptable for obsolete parts
• Lens Transparency: Diffused or Clear
• Lens Color: White or Colorless
• Millicandela Rating: Variation permitted based on lens transparency differences
• Viewing Angle: Variation permitted based on lens transparency differences
• Height (Max): Minor variation permitted within mechanical constraints
• Packaging: Bulk or Tape acceptable for through-hole components

Two substitute parts meet these criteria and are grouped as follows:

Group 1 - Direct Functional Equivalent: 3SBC (Active status, identical electrical specifications, diffused lens matching)

Group 2 - Enhanced Brightness Alternative: 3SBCC-F (Active status, identical electrical specifications, clear lens with increased brightness output)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 3SBC is the primary substitute for the obsolete 3SBC-F. Both components share identical electrical characteristics, forward voltages, test currents, wavelengths, and optical properties. The 3SBC is currently in active production status and carries ROHS3 compliance certification. The 4.50mm maximum height of the 3SBC is lower than the 3SBC-F (5.30mm), which may provide mechanical advantages in space-constrained applications. Bulk packaging is available for production quantities.

For Enhanced Brightness Applications:

The 3SBCC-F provides an alternative when increased light output is required. This part maintains identical electrical specifications and wavelengths but features a clear lens instead of diffused optics, resulting in 60mcd green and 100mcd red output—approximately 7.5 times greater brightness than the 3SBC-F. The narrower 20° viewing angle concentrates light output in a focused beam pattern. The 3SBCC-F is active production status with ROHS3 compliance. Selection of this part requires verification that the narrower viewing angle and increased brightness are compatible with the application's optical and electrical design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3SBC directly replace the 3SBC-F without circuit modifications?

A: Yes. The 3SBC maintains identical forward voltages (2.1V green, 1.7V red), test currents (20mA per color), and wavelengths (568nm green, 645nm red). No circuit modifications are required. The lower maximum height (4.50mm vs. 5.30mm) may provide additional mechanical clearance.

Q: What is the primary difference between the 3SBC and 3SBCC-F?

A: The primary difference is lens transparency and resulting brightness output. The 3SBC features a diffused white lens with 8mcd green and 12mcd red output. The 3SBCC-F features a clear colorless lens with 60mcd green and 100mcd red output. Both maintain identical electrical specifications. The 3SBCC-F also has a narrower 20° viewing angle compared to the 3SBC's 45° viewing angle.

Q: Is the 3SBCC-F suitable as a direct replacement for the 3SBC-F?

A: The 3SBCC-F is electrically compatible but introduces optical differences. The increased brightness and narrower viewing angle may alter the visual appearance and performance characteristics in the application. Selection requires confirmation that the optical properties are acceptable for the intended use.

Q: What packaging options are available for production quantities?

A: Both substitute parts (3SBC and 3SBCC-F) are available in bulk packaging suitable for production assembly. The 3SBC-F was available in standard packaging; substitute parts maintain compatibility with standard through-hole assembly processes.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both the 3SBC and 3SBCC-F carry ROHS3 compliance certification. The original 3SBC-F RoHS status was not specified in the available documentation.

Q: Can these parts be used interchangeably in existing designs?

A: The 3SBC is fully interchangeable with the 3SBC-F. The 3SBCC-F is electrically interchangeable but introduces optical differences due to lens transparency and brightness variations. Application-specific validation is required before substituting the 3SBCC-F in existing designs.
