KB2620EW LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The KB2620EW is an active LED Circuit Board Indicator manufactured by Kingbright, configured as a quad red LED bar in DIP format with through-hole mounting. This component is designed for applications requiring visual status indication on printed circuit boards. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), indicating suitability for standard storage and handling conditions. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB2620EW is determined by strict alignment of the following critical parameters:

Configuration Match: Both main and substitute parts must maintain Bar - 4 Wide, DIP configuration to ensure mechanical fit and pin compatibility on target PCBs.

Electrical Parameters: Forward current rating of 30mA is the controlling specification. Substitute parts must operate at identical current levels to maintain circuit design integrity without requiring redesign of current-limiting resistor networks.

Color and Wavelength: Red LED color (x 4) is functionally required. Wavelength peak values within the red spectrum (627nm to 636nm) are acceptable as they represent standard red LED performance bands and do not require optical system redesign.

Voltage Rating: Forward voltage specifications of 2V to 2.1V are compatible within standard circuit design tolerances for LED indicator applications, as this voltage range falls within typical series resistor compensation capability.

Lens Characteristics: Diffused white lens type is maintained across all parts to ensure consistent light distribution and visibility characteristics.

Mounting Type: Through-hole mounting is preserved to maintain PCB assembly compatibility.

Compliance: ROHS3 compliance and MSL 1 rating are required for equivalent substitution in regulated applications.

The SSB-LX2620IW from Lumex Opto/Components Inc. meets all substitution criteria based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both KB2620EW and SSB-LX2620IW are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, qualifying them for equivalent substitution in circuit board indicator applications. The forward voltage differential of 0.1V (2V vs. 2.1V) is within standard design tolerance for LED indicator circuits and does not require circuit modification. The wavelength peak variation of 9nm (627nm vs. 636nm) remains within the red LED spectrum and does not necessitate optical system redesign. The millicandela rating difference of 2mcd (27mcd vs. 25mcd) represents a 7% variance in luminous intensity, which is acceptable for indicator-class applications where precise brightness matching is not a critical design parameter. Both parts maintain identical DIP configuration, current rating, and through-hole mounting characteristics, ensuring direct mechanical and electrical compatibility on existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can SSB-LX2620IW be used as a direct replacement for KB2620EW without PCB modification?

A: Yes. Both parts share identical DIP configuration, 30mA current rating, through-hole mounting, and diffused white lens type. No PCB layout changes are required for substitution.

Q: What is the significance of the 0.1V forward voltage difference between the two parts?

A: The forward voltage difference of 0.1V (KB2620EW at 2V, SSB-LX2620IW at 2.1V) falls within standard design tolerance for LED indicator circuits. Series resistor networks in typical applications accommodate this variance without requiring recalculation or component changes.

Q: Does the wavelength peak difference of 9nm affect circuit performance?

A: No. Both wavelengths (627nm and 636nm) fall within the standard red LED spectrum. This difference is not perceptible to the human eye in indicator applications and does not require optical system redesign.

Q: Is the 2mcd difference in millicandela rating significant for indicator applications?

A: The 7% variance in luminous intensity (27mcd vs. 25mcd) is acceptable for circuit board indicator applications where brightness matching is not a critical design requirement. Both parts provide adequate visibility for status indication purposes.

Q: Are both parts suitable for regulated or compliance-sensitive applications?

A: Yes. Both KB2620EW and SSB-LX2620IW carry ROHS3 compliance certification and MSL 1 (unlimited) moisture sensitivity ratings, qualifying them for use in regulated environments and standard storage conditions.

Q: What packaging format is available for the substitute part?

A: SSB-LX2620IW is supplied in tube packaging, whereas KB2620EW packaging format is not specified in the provided data. Verify packaging requirements for your procurement and assembly processes.

Q: Can these parts be used interchangeably in new designs?

A: Yes. Both parts meet identical electrical and mechanical specifications for DIP quad LED bar indicator applications. Either part can be selected for new designs based on availability and supply chain considerations.
