Equivalent & Substitute Parts for 3BC-3-R/Y

Part Overview

The 3BC-3-R/Y is a dual-color LED indicator manufactured by Bivar Inc., featuring integrated red and yellow light-emitting elements in a single T-1 (3mm) through-hole package. This component is classified as obsolete and is used for visual indication applications requiring both red and yellow signal states.

Due to the obsolete product status of the 3BC-3-R/Y, locating replacement inventory from original stock channels presents supply chain challenges. The substitute part 3BC-3-R/Y-F provides functional and electrical equivalence while maintaining active product status and current manufacturing availability.

Engineering Selection Recommendations

The 3BC-3-R/Y-F is the appropriate selection for new designs and component replenishment due to the following factors:

Product Status Consideration: The 3BC-3-R/Y is classified as obsolete, indicating discontinued manufacturing and limited inventory availability. The 3BC-3-R/Y-F maintains active product status with confirmed manufacturing support and current stock levels (1054 pieces available).

Compliance and Certification: The 3BC-3-R/Y-F carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Electrical and Mechanical Compatibility: All critical electrical parameters (forward voltage, test current, luminous intensity, wavelength) and mechanical parameters (package configuration, physical dimensions, mounting type) are identical between the main part and substitute. Direct pin-for-pin and functional replacement is supported without circuit modification.

Supply Chain Continuity: Selection of the 3BC-3-R/Y-F ensures continued availability and eliminates obsolescence-related procurement delays.

Frequently Asked Questions (FAQ)

Q: Can the 3BC-3-R/Y-F be used as a direct replacement for the 3BC-3-R/Y in existing circuit designs?

A: Yes. The 3BC-3-R/Y-F is electrically and mechanically equivalent to the 3BC-3-R/Y. All forward voltage specifications, test currents, luminous intensity ratings, wavelength characteristics, and physical dimensions are identical. No circuit modifications are required.

Q: What is the difference between the 3BC-3-R/Y and 3BC-3-R/Y-F?

A: The primary differences are product status and packaging. The 3BC-3-R/Y is obsolete with limited inventory availability. The 3BC-3-R/Y-F is an active product with current manufacturing support and bulk packaging availability. All electrical and mechanical specifications are identical.

Q: Are the lens characteristics the same between both parts?

A: Yes. Both parts feature identical 3mm T-1 lens specifications, including white diffused lens material, round domed top style, and 40-degree viewing angle.

Q: Does the 3BC-3-R/Y-F meet current environmental compliance standards?

A: Yes. The 3BC-3-R/Y-F is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What is the common cathode configuration?

A: Common cathode configuration means both the red and yellow LED elements share a single cathode connection, with separate anode connections for each color. This configuration requires a single common ground connection and individual positive voltage connections for each color element.

Q: Are the optical characteristics identical?

A: Yes. Both parts have identical millicandela ratings (30mcd Red, 20mcd Yellow), peak wavelengths (625nm Red, 590nm Yellow), lens transparency (diffused), and viewing angle (40°).

Q: What is the moisture sensitivity level, and does it affect storage or handling?

A: Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard electronic component storage and handling practices apply.
