R5BC-Y/G LED Equivalent & Substitute Parts

Part Overview

The R5BC-Y/G is a through-hole mounted bi-color LED indicator manufactured by Bivar Inc., featuring green and yellow light emission in a diffused rectangular lens package. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

The R5BC-Y/G provides discrete LED indication with a white diffused lens, 4.90mm x 1.90mm lens dimensions, and dual-color capability (green at 2.1V, yellow at 2V forward voltage). Due to its obsolete status, sourcing alternatives that maintain electrical and mechanical compatibility is necessary for system maintenance and new production builds.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the R5BC-Y/G is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Dual-color (green/yellow) LED configuration
• Forward voltage range: Green 2.1V ±0.2V, Yellow 2V ±0.2V
• Test current: 20mA for both colors
• Millicandela rating: Minimum 3mcd for both colors
• Viewing angle: 120° ±10°

Mechanical Compatibility Criteria:

• Through-hole radial mounting type
• Diffused lens transparency
• Rectangle with flat top lens style
• Lens size: 4.90mm x 1.90mm ±0.2mm
• Maximum height: 7.00mm ±0.5mm
• White lens color

Environmental & Compliance Criteria:

• Moisture Sensitivity Level 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8541.41.0000

The XSUGY18M from SunLED meets these substitution criteria with minor parameter variations within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The XSUGY18M from SunLED is a direct functional equivalent for the obsolete R5BC-Y/G. Selection of this substitute is supported by the following factors:

Electrical Alignment: Forward voltage specifications for both green and yellow channels fall within standard engineering tolerance bands (±0.1V). The XSUGY18M exhibits slightly higher millicandela ratings (5mcd green, 3.8mcd yellow versus 3mcd for both colors on the R5BC-Y/G), which represents improved brightness performance without introducing incompatibility.

Mechanical Alignment: Both components share identical through-hole radial mounting architecture, maximum height (7.00mm), and diffused rectangular lens styling. Lens dimensions vary by 0.1mm in each axis, remaining within standard manufacturing tolerances for this component class.

Compliance & Availability: The XSUGY18M carries active product status with RoHS3 compliance and REACH unaffected designation, ensuring long-term supply chain viability. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, simplifying regulatory documentation.

Moisture Sensitivity: Both components maintain MSL 1 (Unlimited) rating, indicating no moisture-related handling restrictions during assembly or storage.

Frequently Asked Questions (FAQ)

Q: Can the XSUGY18M directly replace the R5BC-Y/G in existing circuit designs?

A: Yes. The XSUGY18M maintains electrical compatibility across all critical parameters: dual green/yellow color output, 20mA test current, and forward voltage specifications within standard tolerance. Mechanical compatibility is confirmed through identical mounting type (through-hole radial), package height (7.00mm), and lens configuration (diffused rectangle).

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Bivar Inc. versus SunLED), product status (obsolete versus active), and brightness ratings. The XSUGY18M provides higher millicandela output (5mcd green, 3.8mcd yellow) compared to the R5BC-Y/G (3mcd both colors). Lens dimensions differ by 0.1mm per axis (5.00mm x 2.00mm versus 4.90mm x 1.90mm) and viewing angle is 110° versus 120°. These variations remain within acceptable engineering tolerances for LED indicator applications.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The XSUGY18M carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Will the higher brightness of the XSUGY18M affect circuit operation?

A: The increased millicandela rating of the XSUGY18M does not alter electrical circuit behavior. LED brightness is determined by forward current and forward voltage, both of which remain constant at 20mA and 2.1V/2.0V respectively. The higher brightness results from improved LED die efficiency and does not require circuit modification.

Q: What is the viewing angle difference between these parts?

A: The R5BC-Y/G provides 120° viewing angle while the XSUGY18M provides 110° viewing angle. This 10° difference falls within standard engineering tolerance for LED indicator applications and does not impact functional compatibility in typical circuit board layouts.

Q: Are there packaging differences between these parts?

A: The R5BC-Y/G is supplied in standard packaging while the XSUGY18M is supplied in bulk packaging. Both use identical radial through-hole package type. Bulk packaging does not affect component electrical or mechanical specifications.
