HLMP2550 LED Indicator Bar - Equivalent & Substitute Parts

Part Overview

The HLMP2550 is a green LED circuit board indicator bar manufactured by onsemi, featuring a single SIP configuration with a 19.05mm x 3.81mm rectangular flat-top lens. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates at 2.2V with a 90mA current rating and delivers 50mcd brightness output at a peak wavelength of 565nm. Identifying compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts for the HLMP2550 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Green (565nm peak wavelength)
• Lens configuration: Rectangle with Flat Top
• Mounting type: Through Hole
• Lens dimensions: Approximately 19mm x 3.8mm
• Voltage rating: 2.1V to 2.2V range
• Millicandela rating: Minimum 8mcd

Substitution Logic: The HLMP-2550 (Broadcom Limited) and LTL-2550G (Lite-On Inc.) are functionally equivalent alternatives. Both maintain the same color, wavelength, lens style, and mounting configuration. Variations in current rating (30mA vs. 90mA vs. 100mA) and millicandela output reflect different LED die designs but do not prevent substitution when circuit design accommodates the electrical differences. Configuration differences (SIP vs. DIP) are acceptable provided the through-hole footprint and lens dimensions align with the application requirements.

Parameter Comparison

Engineering Selection Recommendations

HLMP-2550 (Broadcom Limited) is the primary substitute for the obsolete HLMP2550. This part maintains identical lens dimensions (19.05mm x 3.81mm), voltage rating (2.2V), and millicandela output (50mcd). The part is currently in active production status with ROHS3 compliance certification. The reduced current rating (30mA vs. 90mA) requires circuit design adjustment but provides improved power efficiency. This substitute is recommended for new designs requiring direct form-factor compatibility.

LTL-2550G (Lite-On Inc.) serves as an alternative substitute when the primary option is unavailable. This part maintains the same color, wavelength, and mounting type with nearly identical lens dimensions (19.00mm x 3.76mm vs. 19.05mm x 3.81mm). The configuration differs (DIP vs. SIP), and the millicandela rating is significantly lower (8mcd vs. 50mcd). The higher current rating (100mA) and slightly lower voltage (2.1V) require circuit evaluation. This substitute is suitable for applications where brightness reduction is acceptable and footprint tolerance permits the minor dimensional variation.

Both substitutes carry REACH Unaffected status and EAR99 classification, matching the original part's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-2550 (Broadcom) be used as a direct replacement for the HLMP2550 (onsemi)?

A: Yes. Both parts share identical lens dimensions, voltage rating, and millicandela output. The primary difference is the reduced current rating (30mA vs. 90mA), which requires circuit design adjustment to the current-limiting resistor. The part is pin-compatible and form-factor compatible for through-hole mounting.

Q: What are the key differences between the HLMP-2550 and LTL-2550G?

A: The HLMP-2550 maintains the original SIP configuration and 50mcd brightness. The LTL-2550G uses a DIP configuration with significantly lower brightness (8mcd) but higher current capacity (100mA). Lens dimensions differ slightly (19.00mm x 3.76mm vs. 19.05mm x 3.81mm). The LTL-2550G is suitable only when brightness reduction is acceptable and mechanical tolerance permits the dimensional variation.

Q: Are there packaging differences between these substitutes?

A: The HLMP2550 (onsemi) and HLMP-2550 (Broadcom) are supplied in tube packaging. The LTL-2550G (Lite-On) is also supplied in tube packaging. All three parts use through-hole mounting, ensuring compatibility with standard PCB assembly processes.

Q: Do all substitutes meet the same compliance standards?

A: The HLMP-2550 (Broadcom) and LTL-2550G (Lite-On) both carry ROHS3 compliance certification. All three parts are REACH Unaffected and classified as EAR99. The original HLMP2550 (onsemi) does not specify RoHS status but shares the same REACH and ECCN classification.

Q: What should be considered when selecting between the two substitutes?

A: Selection depends on application requirements. Choose HLMP-2550 (Broadcom) for designs requiring the original brightness level (50mcd) and SIP configuration. Choose LTL-2550G (Lite-On) only when brightness reduction is acceptable, current capacity must exceed 90mA, and mechanical tolerance permits the minor lens dimension variation. Both parts are currently in active production, ensuring supply availability.
