HLMP2755 LED Indicator Bar - Equivalent & Substitute Parts

Part Overview

The HLMP2755 is a yellow LED circuit board indicator bar manufactured by onsemi, featuring an 8.89mm square lens with flat top design in DIP configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity. The part operates at 2.1V with 60mA current rating and delivers 38mcd brightness output at a peak wavelength of 583nm. Substitute parts maintain compatibility through matching electrical specifications, mechanical form factor, and mounting characteristics while offering active product status and current manufacturing availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLMP2755 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Parameters:

• Voltage Rating: 2.1V (all substitutes match)
• Color: Yellow (all substitutes match)
• Peak Wavelength: 583nm ±5nm range (583nm to 588nm acceptable)
• Configuration: Bar - Single, DIP (all substitutes match)

Mechanical Compatibility Parameters:

• Lens Size: 8.89mm (all substitutes match)
• Mounting Type: Through Hole (all substitutes match)
• MSL Rating: 1 (Unlimited) (all substitutes match)

Operational Considerations: Current ratings vary among substitutes (25mA to 80mA), requiring circuit design verification. Millicandela ratings differ, affecting brightness output. Lens type variations (clear vs. diffused) impact light distribution characteristics. All substitutes maintain DIP through-hole mounting compatibility and operate at identical voltage levels.

Parameter Comparison

Engineering Selection Recommendations

HLMP-2755 (Broadcom Limited) - Active product status with ROHS3 compliance. Maintains identical voltage and wavelength specifications. Current rating of 25mA requires series resistor adjustment compared to original 60mA design. Millicandela rating of 70mcd provides increased brightness output. Recommended for applications where reduced power consumption is acceptable and higher brightness is beneficial.

KB2755YW (Kingbright) - Active product status with ROHS3 compliance. Wavelength of 588nm remains within acceptable yellow LED spectrum. Current rating of 30mA requires circuit modification. Millicandela rating of 24mcd is lower than original specification. Lens type specified as diffused white, affecting light distribution. Suitable for applications tolerating reduced brightness output.

LTL-2755Y (Lite-On Inc.) - Active product status with ROHS3 compliance. Wavelength of 585nm maintains yellow spectrum compatibility. Current rating of 80mA exceeds original specification, requiring circuit design review. Millicandela rating of 8mcd is significantly lower than original. Lens type specified as diffused. Recommended only where brightness reduction is acceptable and higher current capacity is required.

All three substitutes provide active manufacturing status and current availability, addressing the obsolescence of the original HLMP2755 component.

Frequently Asked Questions (FAQ)

Q: Can HLMP-2755 (Broadcom) be used as a direct replacement for HLMP2755 (onsemi)?

A: Electrical and mechanical compatibility is confirmed through matching voltage (2.1V), wavelength (583nm), configuration (Bar - Single, DIP), lens size (8.89mm), and mounting type (Through Hole). However, the current rating differs (25mA vs. 60mA), requiring circuit resistor recalculation. The higher millicandela rating (70mcd vs. 38mcd) increases brightness output.

Q: What are the key differences in current ratings among substitutes?

A: HLMP-2755 operates at 25mA, KB2755YW at 30mA, and LTL-2755Y at 80mA, compared to the original 60mA. Each requires independent circuit design verification to ensure proper LED operation and component protection through appropriate series resistance.

Q: How do wavelength variations affect substitution?

A: All substitutes maintain yellow LED color specification within the range of 583nm to 588nm peak wavelength. These variations fall within acceptable yellow LED spectrum parameters and do not affect functional compatibility for indicator applications.

Q: Are all substitutes through-hole mounted?

A: Yes. All substitute parts maintain through-hole mounting configuration with 8.89mm lens size, ensuring mechanical compatibility with existing PCB layouts designed for the HLMP2755.

Q: What compliance certifications apply to substitute parts?

A: All three substitute parts carry ROHS3 compliance certification and maintain MSL Rating 1 (Unlimited) moisture sensitivity level, matching the environmental specifications of the original component.

Q: Does lens type affect substitution suitability?

A: Lens type variations exist among substitutes. HLMP-2755 and LTL-2755Y specify square with flat top design, while KB2755YW specifies diffused white lens type. Diffused lenses alter light distribution characteristics and may affect visual appearance in applications requiring specific light patterns.
