QTLP9132YR Red LED SMD Equivalent & Substitute Parts

Part Overview

The QTLP9132YR is an active red LED indication component manufactured by Everlight Electronics Co Ltd, designed for surface mount applications in discrete 2-SMD yoke bend configuration. This part is a T-3/4 form factor red diffused LED with 15mcd brightness rating and 2V forward voltage, suitable for standard indication applications requiring red light output at 635nm peak wavelength.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across different manufacturers. The QTLP9132YR remains in active production status with 2300 pieces in current inventory.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTLP9132YR is determined by the following critical parameters:

Mechanical Compatibility:

• Mounting type must be Surface Mount
• Package configuration must be 2-SMD, Yoke Bend
• Physical dimensions must accommodate PCB layout constraints (height, length, width)

Electrical Compatibility:

• Color must be Red
• Peak wavelength must be in the red spectrum (620–650nm range)
• Forward voltage (Vf) must be compatible with existing circuit design (±0.5V tolerance acceptable for standard indication circuits)
• Millicandela rating must support the intended indication function

Compliance & Certification:

• RoHS3 compliance required
• ECCN classification must match (EAR99)
• HTSUS code must match (8541.41.0000)

The HLMP-6305-L0021 from Broadcom Limited meets these substitution criteria with compatible mechanical form factor, red color output, and full compliance certifications.

Engineering Selection Recommendations

Primary Part: QTLP9132YR

The QTLP9132YR remains the specified component for designs requiring 15mcd brightness output with diffused lens characteristics. This part is in active production status with adequate inventory (2300 pieces) and full ROHS3 compliance certification.

Substitute Part: HLMP-6305-L0021

The HLMP-6305-L0021 from Broadcom Limited is qualified as a substitute when:

1. Brightness increase is acceptable: The 40mcd output is higher than the original 15mcd specification. Circuit current-limiting resistors must be verified to ensure the substitute does not exceed maximum rated current.

2. Lens transparency change is acceptable: The clear lens (versus diffused) produces a more focused light beam with 28° viewing angle instead of 50°. Application requirements must confirm this narrower beam pattern is suitable.

3. Forward voltage difference is managed: The 1.8V Vf (versus 2.0V) requires verification that existing series resistor values maintain proper operating current. The 0.2V difference is within typical circuit tolerance for indication applications.

4. Compliance requirements are met: Both parts carry ROHS3 compliance, EAR99 ECCN classification, and matching HTSUS codes (8541.41.0000).

5. Physical form factor is compatible: Mechanical dimensions (height, length, width) are within acceptable tolerance for PCB layout and assembly processes.

Both parts are active production items with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can HLMP-6305-L0021 be used as a direct drop-in replacement for QTLP9132YR?

A: The HLMP-6305-L0021 is mechanically compatible (2-SMD yoke bend package, surface mount) and electrically compatible (red color, 635nm peak wavelength, ROHS3 compliant). However, the substitute has higher brightness (40mcd vs 15mcd) and a narrower viewing angle (28° vs 50°). Circuit verification is required to confirm the brightness increase and viewing angle change are acceptable for the application.

Q: What is the key difference in lens characteristics between these parts?

A: The QTLP9132YR features a diffused lens that scatters light over a wider 50° viewing angle with lower brightness concentration. The HLMP-6305-L0021 has a clear lens that produces a more focused beam with 28° viewing angle and higher brightness (40mcd). Application requirements determine which lens type is appropriate.

Q: Are there forward voltage compatibility concerns?

A: The QTLP9132YR has 2.0V Vf while the HLMP-6305-L0021 has 1.8V Vf. This 0.2V difference is typical for red LEDs from different manufacturers. For standard indication circuits with series current-limiting resistors, this difference is generally acceptable. Verify that existing resistor values maintain proper operating current for the substitute part.

Q: What compliance certifications apply to both parts?

A: Both the QTLP9132YR and HLMP-6305-L0021 are ROHS3 compliant, classified as EAR99 for export control, and carry HTSUS code 8541.41.0000. Both parts are in active production status.

Q: How do the test current specifications differ?

A: The QTLP9132YR is tested at 20mA while the HLMP-6305-L0021 is tested at 10mA. These are manufacturer test conditions and do not represent maximum operating current. Actual circuit operating point depends on series resistor value and supply voltage. Verify that the substitute part's maximum rated current is not exceeded in the application circuit.

Q: Are there packaging differences between these parts?

A: The QTLP9132YR is supplied in standard packaging (not specified in detail), while the HLMP-6305-L0021 is supplied in Tape & Reel (TR) format. Both use 2-SMD yoke bend package configuration suitable for automated assembly. Verify tape reel compatibility with assembly equipment if substituting.
