LED GRN/YLW DIFFUSED T-1 3/4 T/H 5BC-Y/G Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5BC-Y/G is a bidirectional LED indicator featuring green and yellow light emission in a T-1 3/4 through-hole package. This component provides discrete indication with diffused lens optics and radial lead configuration. The 5BC-Y/G is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain electrical performance, mechanical compatibility, and optical characteristics within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 5BC-Y/G is determined by the following critical parameters:

Electrical Compatibility: Forward voltage specifications (2.1V Green, 2V Yellow) and test current (20mA) must remain constant. These parameters ensure direct circuit compatibility without modification to current-limiting resistor networks or power supply configurations.

Optical Compatibility: Wavelength peak values (568nm Green, 590nm Yellow), lens transparency (diffused), and viewing angle (45°) establish visual performance equivalence. Millicandela ratings must support the intended indication function within the application context.

Mechanical Compatibility: Package type (Radial, T-1 3/4), lens size (5mm), and maximum height (8.50mm nominal) ensure physical fit within PCB layouts and enclosure constraints. Through-hole mounting configuration remains constant.

Configuration: Bidirectional color configuration (green and yellow) must be maintained for dual-indication applications.

The substitute part 5BC-Y/G-F meets all critical parameters with documented variations noted in the parameter comparison table.

Engineering Selection Recommendations

The 5BC-Y/G-F serves as a direct substitute for the obsolete 5BC-Y/G based on electrical and mechanical parameter equivalence. The substitute part is in active production status, ensuring long-term availability and supply chain continuity.

Documented Variations:

The 5BC-Y/G-F exhibits a +1mcd increase in yellow millicandela rating (6mcd versus 5mcd) and a +0.10mm increase in maximum height (8.60mm versus 8.50mm). These variations remain within typical manufacturing tolerances for LED indicators and do not compromise functional compatibility in standard indication applications.

The 5BC-Y/G-F carries ROHS3 compliance certification, providing environmental and regulatory documentation not specified for the original part.

Packaging Consideration:

The substitute part is supplied in bulk packaging format, whereas the original part specification references tape and reel format. Procurement and assembly processes must accommodate this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can the 5BC-Y/G-F replace the 5BC-Y/G in existing circuit designs without modification?

A: Yes. The 5BC-Y/G-F maintains identical forward voltage (2.1V Green, 2V Yellow), test current (20mA), wavelength peak (568nm Green, 590nm Yellow), and viewing angle (45°) specifications. Circuit designs require no modification. The +1mcd yellow variation and +0.10mm height variation do not affect electrical circuit operation.

Q: What is the significance of the millicandela rating difference?

A: The 5BC-Y/G-F provides 6mcd yellow output compared to 5mcd in the original part. This represents a 20% increase in yellow light intensity. For indication applications where brightness is not a limiting constraint, this variation is acceptable. Applications requiring exact brightness matching should evaluate the specific indication requirements.

Q: Does the height difference affect PCB layout compatibility?

A: The 5BC-Y/G-F maximum height is 8.60mm compared to 8.50mm for the original part, a difference of 0.10mm. This variation is negligible for standard through-hole PCB layouts and does not affect component clearance in typical enclosure designs. Verify clearance in applications with height-constrained designs.

Q: What is the difference between tape and reel and bulk packaging?

A: Tape and reel packaging is used for automated assembly processes, while bulk packaging is used for manual assembly or alternative handling methods. The electrical and mechanical specifications of the component remain identical. Procurement and assembly processes must be adapted to the bulk packaging format.

Q: Is the 5BC-Y/G-F RoHS compliant?

A: Yes. The 5BC-Y/G-F is ROHS3 compliant. RoHS compliance documentation is provided for the substitute part. Original part RoHS status was not specified in available documentation.

Q: Are there any other substitute parts available for the 5BC-Y/G?

A: Based on provided data, the 5BC-Y/G-F is the documented substitute. Additional alternatives may exist from other manufacturers, but only the 5BC-Y/G-F is confirmed as a Bivar Inc. direct substitute with equivalent electrical and mechanical specifications.
