HLMP-2835 Equivalent & Substitute Parts

Part Overview

The HLMP-2835 is a LED Circuit Board Indicator with a 2-segment bar configuration in green, manufactured by Broadcom Limited. This through-hole component operates at 2.2V with a 20mA current rating and delivers 50mcd brightness. The part is currently obsolete, making identification of compatible substitutes essential for ongoing maintenance, repair, and redesign applications where this component is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HLMP-2835 is determined by the following critical parameters:

• Color and Wavelength: Green (x 2) at 565nm peak wavelength
• Configuration: Bar - 2 High, DIP arrangement
• Voltage Rating: 2.2V nominal operating voltage
• Mounting Type: Through Hole
• Electrical Compatibility: Current rating and brightness output must support the original circuit design

The KB2835SGD from Kingbright meets these core substitution criteria. Both parts share identical color, wavelength, configuration, voltage rating, and mounting type. The substitute part is currently in active production status, ensuring long-term availability compared to the obsolete HLMP-2835.

Parameter Comparison

Engineering Selection Recommendations

The KB2835SGD is the manufacturer-recommended substitute for the obsolete HLMP-2835. Selection of this substitute is supported by:

• Product Status: The KB2835SGD is in active production, ensuring availability for current and future applications, whereas the HLMP-2835 is obsolete.
• Compliance: The KB2835SGD meets ROHS3 environmental standards, aligning with modern manufacturing and regulatory requirements.
• Electrical Compatibility: Both parts operate at 2.2V with compatible current ratings (20mA original vs. 25mA substitute). The substitute's higher current rating does not create incompatibility with existing circuit designs.
• Functional Equivalence: Identical color, wavelength, configuration, and mounting type ensure direct functional replacement in through-hole PCB applications.

The reduction in millicandela rating (50mcd to 25mcd) represents a visual brightness difference that must be evaluated within the context of the specific application. For indicator applications where the original brightness was not critical to function, this substitute is appropriate. For applications requiring the original brightness specification, alternative substitutes with higher mcd ratings should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the KB2835SGD be used as a direct replacement for the HLMP-2835 in existing PCB designs?

A: Yes. Both parts share identical voltage rating (2.2V), configuration (Bar - 2 High, DIP), color (Green x 2), and mounting type (Through Hole). The substitute's 25mA current rating is compatible with circuits designed for the original 20mA specification. PCB footprints and lead spacing are compatible for through-hole mounting.

Q: What is the difference in brightness between these two parts?

A: The HLMP-2835 is rated at 50mcd, while the KB2835SGD is rated at 25mcd. This represents a 50% reduction in peak brightness. For indicator applications where brightness is not a critical performance parameter, this difference is typically acceptable. Applications requiring the original brightness level should evaluate alternative substitutes.

Q: Are there any compliance or regulatory differences between the HLMP-2835 and KB2835SGD?

A: The KB2835SGD meets ROHS3 environmental compliance standards, whereas the HLMP-2835 does not specify RoHS status. Both parts are REACH Unaffected and carry the same EAR99 export classification. The KB2835SGD aligns with current environmental and regulatory requirements for electronic components.

Q: Why is the HLMP-2835 obsolete?

A: The HLMP-2835 has been discontinued by Broadcom Limited. The KB2835SGD from Kingbright is the manufacturer-recommended active substitute, ensuring continued availability and support for applications requiring this component type.

Q: Are the physical dimensions compatible between these parts?

A: Both parts are through-hole mounted with Bar - 2 High, DIP configuration. The KB2835SGD specifies lens dimensions of 8.89mm x 3.81mm with a Rectangle with Flat Top style. The HLMP-2835 does not provide detailed dimensional specifications. For applications with strict mechanical constraints, physical verification of the substitute part is recommended before production implementation.
