3BC-A/G LED Amber/Green Diffused T-1 Through Hole

Part Overview

The 3BC-A/G is a bidirectional LED indicator from Bivar Inc. featuring Amber and Green color options in a T-1 through-hole package. This part provides dual-color indication capability with a 3mm diffused lens. The product is currently obsolete, necessitating identification of functionally equivalent active alternatives for continued system designs and repairs.

Key Parameters

Substitute Part Grouping Explanation

The 3BC-A/G can be substituted with the 3BC-Y/G based on the following allowable parameters:

Key Substitution Criteria:

• Identical lens size (3mm T-1)
• Identical lens style (Round with Domed Top)
• Identical lens color (White)
• Identical lens transparency (Diffused)
• Identical package configuration (Radial Through Hole)
• Identical mounting type (Through Hole)
• Identical maximum height (4.50mm)
• Identical viewing angle (45°)
• Compatible forward voltage range (2V-2.1V per channel)
• Compatible test current (20mA per channel)
• Identical MSL rating (1 - Unlimited)

The primary difference is the LED color pairing: the 3BC-A/G provides Amber/Green indication, while the 3BC-Y/G provides Green/Yellow indication. Both parts maintain identical electrical and mechanical parameters, enabling direct mechanical and functional substitution in applications where the specific color combination is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The 3BC-Y/G is a direct substitute for the obsolete 3BC-A/G when color combination compatibility is confirmed in the application. The substitute part maintains identical mechanical mounting, electrical operating parameters, and optical characteristics. The 3BC-Y/G is an active product with ROHS3 compliance, offering superior availability and compliance assurance compared to the obsolete 3BC-A/G.

Selection of the 3BC-Y/G over the 3BC-A/G requires only that the application can accommodate Green and Yellow indication in place of the original Amber and Green pairing. All other electrical and mechanical requirements are satisfied identically.

Frequently Asked Questions (FAQ)

Q: Can the 3BC-Y/G directly replace the 3BC-A/G in a circuit? A: Yes, provided the application can accept the color change from Amber/Green to Green/Yellow. The electrical voltage requirements (2V-2.1V), test current (20mA), viewing angle (45°), and physical package (3mm T-1 through-hole radial) are identical.

Q: Are the lens and optical characteristics the same? A: Yes. Both parts feature identical lens specifications: 3mm T-1 size, white color, diffused transparency, and round domed top style. The viewing angle is identical at 45°.

Q: What is the primary reason for substitution? A: The 3BC-A/G is obsolete. The 3BC-Y/G is an active product from the same manufacturer, offering continued availability and ROHS3 compliance.

Q: Do the brightness specifications differ? A: The millicandela ratings differ by color. The 3BC-A/G provides 6mcd Amber and 6mcd Green. The 3BC-Y/G provides 6mcd Green and 4mcd Yellow. The secondary color (Yellow) is rated at 4mcd versus the original Green at 6mcd.

Q: Are the mounting requirements identical? A: Yes. Both parts use through-hole radial mounting with identical maximum height of 4.50mm, fitting identical PCB footprints and layout requirements.

Q: What compliance certifications apply to the substitute? A: The 3BC-Y/G is ROHS3 compliant and carries the same ECCN (EAR99) and HTSUS (8541.41.0000) classifications as the original part.
