HLMP6600AGR Equivalent & Substitute Parts

Part Overview

The HLMP6600AGR is a red diffused subminiature T-3/4 surface mount LED manufactured by onsemi, designed for indication applications requiring 5V operation. This component features a 626nm dominant wavelength with 5mcd brightness rating and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP6600AGR is determined by the following critical parameters:

• Color and wavelength matching (Red, 626nm dominant / 635nm peak)
• Forward voltage compatibility (5V operation)
• Diffused lens transparency
• Functional brightness range (millicandela rating)
• Viewing angle characteristics
• Compliance and regulatory status

The HLMP-1600 qualifies as a functional substitute based on matching color, wavelength, forward voltage, lens transparency, and compliance certifications. However, differences in mounting type (through hole vs. surface mount), package configuration, and brightness rating must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-1600 is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for the obsolete HLMP6600AGR. Both components share identical forward voltage (5V), dominant wavelength (626nm), and diffused lens characteristics, establishing electrical and optical compatibility.

Selection of the HLMP-1600 requires design accommodation for mounting type conversion from surface mount to through hole and package reconfiguration from 2-SMD gull wing to radial. The HLMP-1600 exhibits lower brightness (2.1mcd vs. 5mcd) and narrower viewing angle (60° vs. 90°), which may impact visibility in specific application contexts. Current draw remains equivalent (9.6mA vs. 10mA).

Frequently Asked Questions (FAQ)

Q: Can the HLMP-1600 directly replace the HLMP6600AGR on existing PCBs?

A: Direct PCB replacement is not possible due to different mounting types and package configurations. The HLMP6600AGR uses surface mount (2-SMD gull wing), while the HLMP-1600 requires through hole mounting (radial). PCB redesign or adapter solutions are necessary.

Q: Are the optical characteristics equivalent?

A: Both components share identical color (red), dominant wavelength (626nm), and diffused lens transparency. However, the HLMP-1600 has a narrower viewing angle (60° vs. 90°) and lower brightness rating (2.1mcd vs. 5mcd). Application visibility requirements must be evaluated.

Q: What are the compliance differences?

A: Both components are REACH Unaffected. The HLMP-1600 carries ROHS3 compliance certification, while the HLMP6600AGR does not specify RoHS status. For applications requiring RoHS compliance, the HLMP-1600 is the appropriate selection.

Q: Are the electrical parameters compatible?

A: Yes. Both components operate at 5V forward voltage with equivalent test currents (9.6mA vs. 10mA), ensuring circuit compatibility without modification to current-limiting resistor values.

Q: What is the supply status difference?

A: The HLMP6600AGR is obsolete with limited remaining inventory (764 pcs). The HLMP-1600 is an active product with established supply (6677 pcs in stock), providing long-term procurement reliability.
