Equivalent & Substitute Parts for KB2785YW

Part Overview

The KB2785YW is an active, ROHS3 compliant LED circuit board indicator manufactured by Kingbright. This through-hole mounted yellow diffused LED bar operates at 2.1V with a 30mA current rating and delivers 24mcd luminous intensity at a peak wavelength of 588nm. The component is designed for standard DIP configuration applications requiring single bar LED indicators. Substitute parts are identified when inventory constraints, packaging preferences, or specific application requirements necessitate alternative sourcing while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KB2785YW are classified into two categories based on the degree of parameter alignment:

Direct Substitute (KB2755YW): This Kingbright part maintains identical electrical specifications (2.1V, 30mA, 24mcd, 588nm wavelength) and configuration (Bar - Single, DIP, Through Hole). The primary difference is physical package dimension (8.89×8.89mm versus 8.89×19.05mm) and packaging format (Tube versus standard). This part is suitable for applications where the smaller footprint is acceptable and PCB layout permits the dimensional change.

Similar Substitute (HLMP-2785-EF000): This Broadcom Limited part shares the same voltage rating (2.1V), configuration (Bar - Single, DIP), and mounting type (Through Hole). However, it operates at 25mA current (versus 30mA), delivers 38mcd brightness (versus 24mcd), and has a peak wavelength of 583nm (versus 588nm). The identical physical dimensions (8.89×19.05mm) and series designation (HLMP-2785) indicate mechanical compatibility. This part is suitable when the reduced current draw and increased brightness are acceptable within the application's design parameters.

Parameter Comparison

Engineering Selection Recommendations

KB2755YW Selection Criteria: Choose this direct substitute when inventory availability of the KB2785YW is constrained and the application PCB layout accommodates the reduced physical dimensions (8.89×8.89mm versus 8.89×19.05mm). Electrical performance is identical, and all regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained. Tube packaging is suitable for automated assembly processes.

HLMP-2785-EF000 Selection Criteria: Choose this similar substitute when the application can tolerate a 5mA reduction in operating current (25mA versus 30mA) and increased luminous intensity (38mcd versus 24mcd). The wavelength difference of 5nm (583nm versus 588nm) remains within the yellow LED specification range. Physical dimensions match the main part exactly, ensuring direct PCB compatibility. All regulatory compliance requirements are satisfied. This part is available in bulk packaging format.

Compliance Verification: All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, confirming suitability for standard through-hole assembly and storage conditions without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can KB2755YW be used as a direct replacement for KB2785YW in all applications?

A: KB2755YW is electrically equivalent but has different physical dimensions (8.89×8.89mm versus 8.89×19.05mm). Substitution is valid only if the PCB layout and mechanical mounting accommodate the smaller footprint. Electrical specifications, voltage, current, and brightness are identical.

Q: What are the key differences between KB2785YW and HLMP-2785-EF000?

A: The primary differences are current rating (30mA versus 25mA), millicandela rating (24mcd versus 38mcd), and wavelength (588nm versus 583nm). Physical dimensions and mounting type are identical. The HLMP-2785-EF000 operates at lower current with higher brightness output.

Q: Is the 5nm wavelength difference between KB2785YW (588nm) and HLMP-2785-EF000 (583nm) significant?

A: Both wavelengths fall within the yellow LED specification range. The difference is minor and both parts produce yellow light suitable for standard indicator applications. Visual perception of the color difference is negligible in typical circuit board indicator applications.

Q: Can HLMP-2785-EF000 be used in circuits designed for 30mA operation?

A: HLMP-2785-EF000 is rated for 25mA maximum current. It can be used in circuits designed for 30mA operation, but the component must not exceed its 25mA rating. Circuit current limiting resistors should be adjusted accordingly to ensure the part operates within specification.

Q: Are all three parts ROHS3 compliant?

A: Yes. KB2785YW, KB2755YW, and HLMP-2785-EF000 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, confirming compatibility with standard through-hole assembly and storage processes.

Q: What packaging formats are available for these parts?

A: KB2785YW is supplied in standard packaging (format not specified). KB2755YW is supplied in Tube packaging suitable for automated assembly. HLMP-2785-EF000 is supplied in Bulk packaging format.
