KB2820CGKD Equivalent & Substitute Parts

Part Overview

The KB2820CGKD is an active LED Circuit Board Indicator manufactured by Kingbright. This component is a bar-configuration LED indicator with four green LEDs in a single DIP package, designed for through-hole mounting on circuit boards. The part measures 8.89mm x 3.81mm with a rectangle flat-top lens configuration.

Substitute parts are identified when equivalent LED indicators share the same physical footprint, mounting type, lens dimensions, and core electrical characteristics within acceptable operational ranges. The KB2820CGKD has one identified substitute in the Broadcom Limited product line.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KB2820CGKD are identified based on strict alignment of the following parameters:

Physical Compatibility Requirements:

• Lens Size: 8.89mm x 3.81mm (exact match)
• Lens Style: Rectangle with Flat Top (exact match)
• Mounting Type: Through Hole (exact match)
• Configuration: Bar - 4 Wide, DIP (exact match)

Optical Requirements:

• Color: Green (x 4) (exact match)
• Wavelength - Peak: Within green spectrum range

Electrical Compatibility Criteria:

• Voltage Rating: Within acceptable forward voltage range for LED indicators
• Current Rating: Substitute must support the application's current requirements
• Millicandela Rating: Brightness must be suitable for the intended application

Regulatory Compliance:

• RoHS Status: ROHS3 Compliant (required)
• REACH Status: REACH Unaffected (required)

The HLMP-2820 from Broadcom Limited meets all physical and optical compatibility criteria. Electrical parameters differ within acceptable ranges for LED indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (KB2820CGKD): The KB2820CGKD remains the primary choice when the application requires 150mA current rating and 16mcd brightness specification. This part is ROHS3 compliant and REACH unaffected, meeting all regulatory requirements for active product status.

Substitute Selection (HLMP-2820): The HLMP-2820 is electrically and mechanically compatible as a substitute when the application circuit operates at or below 30mA current and the higher brightness output (25mcd) is acceptable. The 0.1V forward voltage difference (2.2V vs. 2.1V) requires verification in the circuit design to ensure proper LED operation and current limiting resistor calculations remain valid.

Both parts are ROHS3 compliant and REACH unaffected, confirming regulatory compatibility for equivalent substitution.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-2820 directly replace the KB2820CGKD in all applications?

A: Physical and optical compatibility is confirmed. Electrical compatibility depends on application current requirements. The HLMP-2820 is rated for maximum 30mA, while the KB2820CGKD supports 150mA. If the application circuit draws more than 30mA, the HLMP-2820 cannot be used. The 0.1V forward voltage difference must be evaluated in the specific circuit design.

Q: What is the significance of the wavelength difference (574nm vs. 565nm)?

A: Both wavelengths fall within the green spectrum range for LED indicators. The 9nm difference is not visually significant for indicator applications and does not affect functional compatibility.

Q: Does the packaging difference (tube vs. standard) affect compatibility?

A: Packaging format affects supply chain and handling procedures but does not impact electrical or mechanical compatibility. The component itself remains identical.

Q: Are both parts suitable for new designs?

A: Both parts carry active product status and are ROHS3 compliant. Selection should be based on the specific current and brightness requirements of the application circuit.

Q: What must be verified before substituting the HLMP-2820?

A: Verify that the application circuit operates at or below 30mA maximum current. Recalculate current-limiting resistor values to account for the 2.2V forward voltage specification. Confirm that the higher brightness output (25mcd) is acceptable for the intended visual indication function.
