HLMPD1509MP7 Equivalent & Substitute Parts

Part Overview

The HLMPD1509MP7 is a Circuit Board Indicator LED manufactured by onsemi, featuring a single red diffused lens in a 5mm T-1 3/4 through-hole right-angle package. This component is designed for applications requiring low-current LED indication with a 1.6V forward voltage and 1mA operating current. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HLMPD1509MP7 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Red
• Configuration: Single LED
• Mounting Type: Through Hole, Right Angle
• Lens Size: 5mm form factor
• Voltage Rating: Compatible forward voltage (1.6V nominal)
• Current Rating: Low-current operation (1mA nominal)

The substitute part 5501107F from Dialight meets these core requirements while maintaining functional equivalence. Both components operate as single red diffused LEDs in through-hole right-angle packages suitable for circuit board indication applications. The substitute operates at slightly elevated voltage (1.8V) and current (2mA) specifications, which remain within acceptable tolerance for most indicator applications while providing improved brightness characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 5501107F from Dialight is a functional substitute for the obsolete HLMPD1509MP7. Both components share identical mounting characteristics (through-hole, right-angle configuration) and identical moisture sensitivity ratings, ensuring mechanical and environmental compatibility.

The substitute part is currently in active production status, providing supply continuity for applications requiring red circuit board indicator LEDs. Both components maintain REACH compliance and EAR99 export classification.

Electrical parameter differences are minor: the 5501107F operates at 1.8V forward voltage versus 1.6V for the original part, and draws 2mA versus 1mA. These differences are typical within the LED indicator component class and do not preclude substitution in standard indicator applications. The substitute provides a wider viewing angle (50° versus 24°), which may be advantageous in applications requiring broader visibility.

Frequently Asked Questions (FAQ)

Q: Can the 5501107F directly replace the HLMPD1509MP7 in existing designs?

A: Yes. Both components feature identical through-hole right-angle mounting and 5mm form factors. Mechanical fit is equivalent. Electrical operation differs slightly in forward voltage and current specifications, which are within normal tolerance for indicator LED applications.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete versus active), forward voltage (1.6V versus 1.8V), operating current (1mA versus 2mA), brightness (3mcd versus 2mcd), and viewing angle (24° versus 50°). Both are single red diffused LEDs in identical packages.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both components maintain identical REACH compliance status and moisture sensitivity ratings. Both are classified as EAR99 for export purposes.

Q: Does the higher current rating of the substitute affect circuit design?

A: The 5501107F operates at 2mA nominal current versus 1mA for the original part. Circuit designs must accommodate this increased current draw. Series resistor values may require adjustment to maintain proper LED operation within the application's voltage supply constraints.

Q: What is the impact of the wider viewing angle on application performance?

A: The 5501107F provides a 50° viewing angle compared to 24° for the HLMPD1509MP7. This wider angle improves visibility from off-axis positions, which may be beneficial in applications where the LED is not directly facing the observer.
