QTLP9122GR Red LED SMD Equivalent & Substitute Parts

Part Overview

The QTLP9122GR is an active red LED indication component manufactured by Everlight Electronics Co Ltd, designed for surface mount applications in standard configurations. This part is a discrete 2V red LED with a clear lens, rated at 80mcd with a 25° viewing angle and 635nm peak wavelength. The component is housed in a 2-SMD Gull Wing package measuring 2.50mm L x 2.00mm W x 3.00mm H (max).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications align with the original specification, enabling direct replacement in circuit designs where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTLP9122GR is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Color classification (Red)
• Peak wavelength range (635nm nominal)
• Forward voltage (Vf) within acceptable circuit tolerance
• Test current rating
• Millicandela output for indication brightness

Mechanical Compatibility Criteria:

• Mounting type (Surface Mount required)
• Package configuration (2-SMD, Gull Wing)
• Physical dimensions and height constraints
• Lens style and size compatibility

Compliance & Certification Criteria:

• RoHS3 compliance status
• Moisture Sensitivity Level (MSL) rating
• Product status (Active)

The HLMP-6300-F0011 manufactured by Broadcom Limited qualifies as a substitute based on matching mounting type, package configuration, gull wing lead style, surface mount compatibility, and shared RoHS3 compliance. Both components are active products with equivalent mechanical footprints and electrical characteristics suitable for red LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

Both the QTLP9122GR and HLMP-6300-F0011 maintain active product status with ROHS3 compliance certification, confirming ongoing manufacturer support and regulatory alignment for current applications.

The QTLP9122GR operates at 2V forward voltage with 20mA test current and delivers 80mcd output through a clear lens with a 25° viewing angle, suitable for applications requiring concentrated, high-brightness indication.

The HLMP-6300-F0011 operates at 1.8V forward voltage with 10mA test current and delivers 10mcd output through a diffused lens with a 90° viewing angle, suitable for applications requiring wide-angle, lower-brightness indication with reduced glare.

Both components share identical 2-SMD Gull Wing package configuration and surface mount compatibility. Physical dimensions are comparable, with the HLMP-6300-F0011 measuring slightly smaller (2.08mm L x 2.21mm W x 2.92mm H max) versus the QTLP9122GR (2.50mm L x 2.00mm W x 3.00mm H max), confirming PCB layout compatibility.

The HLMP-6300-F0011 carries MSL 2A (4 Weeks) versus the QTLP9122GR MSL 3 (168 Hours), indicating more stringent moisture handling requirements for the Broadcom component.

Selection between these parts depends on circuit requirements for brightness output, viewing angle, forward voltage tolerance, and test current specifications.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-6300-F0011 directly replace the QTLP9122GR in existing PCB designs?

A: Both components share identical 2-SMD Gull Wing package configuration and surface mount footprint compatibility. Physical dimensions are comparable within standard PCB layout tolerances. However, the HLMP-6300-F0011 operates at 1.8V forward voltage versus 2V for the QTLP9122GR, and delivers 10mcd versus 80mcd brightness output. Circuit designs must accommodate these electrical differences through resistor and voltage supply adjustments.

Q: What are the key differences in optical performance between these parts?

A: The QTLP9122GR features a clear lens with 80mcd output and 25° viewing angle, concentrating light output in a narrow beam suitable for focused indication. The HLMP-6300-F0011 features a diffused lens with 10mcd output and 90° viewing angle, distributing light output across a wide viewing area with reduced glare. Application requirements determine which optical characteristic is appropriate.

Q: Are both components suitable for high-volume production?

A: Both the QTLP9122GR and HLMP-6300-F0011 maintain active product status with established supply chains. The QTLP9122GR shows 748 pieces in current inventory; the HLMP-6300-F0011 shows 4336 pieces in current inventory. Both components carry ROHS3 compliance certification and are suitable for production applications.

Q: What moisture handling precautions apply to each component?

A: The QTLP9122GR carries MSL 3 rating (168 Hours), allowing extended exposure to ambient moisture conditions before reflow processing. The HLMP-6300-F0011 carries MSL 2A rating (4 Weeks), requiring more stringent moisture control and shorter storage periods after package opening. Storage and handling procedures must align with the more restrictive MSL requirement when substituting components.

Q: Do both components share the same peak wavelength specification?

A: Both components specify 635nm peak wavelength, confirming color consistency for red LED indication applications. The QTLP9122GR lists 635nm peak wavelength; the HLMP-6300-F0011 lists 626nm dominant wavelength and 635nm peak wavelength. This wavelength alignment ensures color matching in multi-component indicator arrays.
