KB2855CGKD LED Indicator Bar - Equivalent & Substitute Parts

Part Overview

The KB2855CGKD is an active green LED circuit board indicator bar manufactured by Kingbright. This through-hole mounted component features a square flat-top lens design with 8.89mm dimensions, operating at 2.1V and 150mA. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications. Finding equivalent substitute parts becomes necessary when managing supply chain continuity, inventory optimization, or when the primary manufacturer part becomes unavailable while maintaining functional compatibility within system design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB2855CGKD is determined by strict alignment of the following critical parameters:

Physical Compatibility Requirements:

• Lens size: 8.89mm (exact match required for PCB footprint compatibility)
• Lens style: Square with Flat Top (mechanical fit and optical characteristics)
• Mounting type: Through Hole (assembly process compatibility)
• Configuration: Bar - Single, DIP (circuit board layout compatibility)

Optical Compatibility Requirements:

• Color: Green (visual indication consistency)
• Wavelength range: Within acceptable green spectrum (565nm to 574nm)
• Millicandela rating: Minimum 48mcd (brightness visibility threshold)

Electrical Compatibility Requirements:

• Voltage rating: 2.1V to 2.2V (forward voltage tolerance for series resistor calculations)
• Current rating: 30mA to 150mA (circuit design accommodation)

Regulatory & Supply Requirements:

• RoHS3 Compliance (mandatory for regulated applications)
• Product Status: Active (ongoing manufacturer support)
• Packaging: Tube (standard handling and storage)

The HLMP-2855 from Broadcom Limited meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

Primary Part Selection (KB2855CGKD): Select the KB2855CGKD when the design specification explicitly requires 150mA operating current and 2.1V forward voltage. This part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating, supporting long-term supply chain stability.

Substitute Part Selection (HLMP-2855): The HLMP-2855 serves as a functional equivalent when supply constraints affect KB2855CGKD availability. Both parts share identical physical form factors (8.89mm square flat-top lens, through-hole DIP configuration) and maintain ROHS3 compliance. The HLMP-2855 operates at 2.2V (0.1V higher) and 30mA (lower current requirement), requiring circuit design verification to confirm series resistor recalculation remains within acceptable tolerance bands. The brightness output (50mcd) exceeds the minimum requirement (48mcd), ensuring visual indication performance.

Compliance Verification: Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for controlled markets. Moisture sensitivity level (MSL 1) is identical, eliminating storage and handling procedure changes during substitution.

Frequently Asked Questions (FAQ)

Q: Can HLMP-2855 directly replace KB2855CGKD without circuit modification?

A: Physical and optical compatibility is direct. Electrical circuit verification is required. The HLMP-2855 operates at 2.2V forward voltage versus 2.1V, and 30mA versus 150mA. Series resistor values must be recalculated based on your supply voltage and target current to maintain proper LED operation. Brightness output (50mcd) exceeds the original specification (48mcd).

Q: What are the key physical compatibility factors?

A: Both parts feature identical 8.89mm square flat-top lens design, through-hole DIP mounting configuration, and tube packaging. PCB footprint compatibility is guaranteed. No mechanical redesign is required.

Q: Are there wavelength differences between these parts?

A: Peak wavelengths differ slightly (574nm for KB2855CGKD versus 565nm for HLMP-2855), both within the green spectrum. Visual color appearance remains consistent for circuit board indicator applications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both KB2855CGKD and HLMP-2855 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. No compliance changes occur during substitution.

Q: What inventory status should I verify before substitution?

A: Both parts maintain active product status with established manufacturer support. KB2855CGKD has 1028 pcs in stock; HLMP-2855 has 1890 pcs in stock. Verify current availability with your component supplier before finalizing procurement decisions.

Q: Can I use HLMP-2855 in high-current applications?

A: The HLMP-2855 is rated for 30mA maximum current, significantly lower than the KB2855CGKD (150mA). Applications requiring sustained 150mA operation must use the KB2855CGKD or verify that HLMP-2855 current rating satisfies your actual circuit requirements.
