HLMP-AL01-LP000 Equivalent & Substitute Parts

Part Overview

The HLMP-AL01-LP000 is an amber 590nm LED indicator manufactured by Broadcom Limited, designed for discrete indication applications in through-hole mounting configurations. This part operates at a forward voltage of 2V with a test current of 20mA and delivers 775mcd brightness with a 70° viewing angle. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the HLMP-AL01-LP000 is determined by the following critical parameters:

• Color and wavelength matching (Amber, 590nm dominant wavelength)
• Mounting type (Through Hole, Radial package)
• Lens style and size category (Oval with Domed Top, 5mm class)
• Forward voltage compatibility (2V nominal operation)
• Test current specification (20mA)
• Moisture sensitivity level (MSL 1)
• Regulatory compliance (REACH Unaffected, EAR99 classification)

The HLMP-AL71-130DD qualifies as a substitute based on matching all core parameters: identical color, wavelength, mounting type, package style, and regulatory status. Variations in millicandela rating, lens transparency, and physical dimensions represent design improvements while maintaining functional compatibility within the specified parameter envelope.

Engineering Selection Recommendations

The HLMP-AL71-130DD is the qualified substitute for the obsolete HLMP-AL01-LP000. Selection is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical wavelength and color specification (590nm amber) for optical consistency
• Matching mounting type and radial package configuration for direct PCB compatibility
• Forward voltage increase of 0.1V (2V to 2.1V) within typical circuit tolerance ranges
• Enhanced brightness output (3970mcd vs 775mcd) providing improved visibility margin
• ROHS3 compliance certification meeting current regulatory requirements
• Identical moisture sensitivity level and REACH compliance status

Physical height increase (8.91mm to 12.89mm) and lens transparency change (standard to diffused) require mechanical clearance verification and optical performance assessment within the specific application context.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-AL71-130DD be used as a direct replacement for the HLMP-AL01-LP000?

A: Yes, the HLMP-AL71-130DD qualifies as a substitute based on matching color, wavelength, mounting type, package configuration, and regulatory compliance. Circuit design must accommodate the 0.1V forward voltage increase and verify mechanical clearance for the increased height dimension.

Q: What is the impact of the higher millicandela rating on circuit design?

A: The HLMP-AL71-130DD delivers 3970mcd compared to 775mcd in the original part. This increased brightness requires no circuit modification but may necessitate optical performance reassessment if the application has specific visibility or contrast requirements.

Q: Does the diffused lens transparency affect compatibility?

A: The HLMP-AL71-130DD features a diffused lens compared to the standard lens of the HLMP-AL01-LP000. This affects light distribution characteristics and should be evaluated against application-specific optical requirements.

Q: Are there height clearance considerations?

A: The HLMP-AL71-130DD maximum height is 12.89mm compared to 8.91mm for the original part. PCB layout and enclosure design must accommodate this 3.98mm increase to ensure proper component fit.

Q: What regulatory advantages does the substitute provide?

A: The HLMP-AL71-130DD carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions. Both parts maintain REACH Unaffected status and EAR99 classification.
