Key Parameters

Substitute Part Grouping Explanation

Substitution of the QTLP9133GR is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 2V nominal
• Peak wavelength: 585nm (yellow spectrum)
• Surface mount configuration with 2-SMD gull wing package

Mechanical Compatibility:

• Gull wing lead configuration for PCB mounting
• Subminiature form factor suitable for compact assemblies
• Maximum height constraint of 3.00mm

Optical Characteristics:

• Yellow color emission
• Luminous intensity in the 15-20mcd range
• Viewing angle tolerance of 28-50°

The HLMP-6405-J0011 from Broadcom Limited satisfies these substitution criteria through matching electrical specifications (2V Vf, 585nm peak wavelength), identical package configuration (2-SMD gull wing), and compatible mechanical dimensions. The substitute part maintains active product status and current manufacturing support.

Engineering Selection Recommendations

The HLMP-6405-J0011 is the designated substitute for the obsolete QTLP9133GR based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active manufacturing status with current supplier support, eliminating procurement risk associated with the obsolete main part.

Electrical Equivalence: Both components operate at identical 2V forward voltage with peak wavelengths within 2nm of each other (585nm vs. 583nm), ensuring compatible circuit performance in indication applications.

Package Compatibility: Both parts utilize 2-SMD gull wing surface mount configuration with dimensions within acceptable tolerance for direct PCB layout substitution. The substitute part height of 2.92mm is within the 3.00mm maximum constraint.

Compliance Status: The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts carry EAR99 export classification.

Operational Differences: The substitute part operates at reduced test current (10mA vs. 20mA) and delivers increased luminous intensity (20mcd vs. 15mcd). The clear lens transparency differs from the diffused lens of the main part, affecting light distribution characteristics. The narrower viewing angle (28° vs. 50°) concentrates light output in a more directional pattern.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-6405-J0011 directly replace the QTLP9133GR without circuit modification?

A: Direct substitution is possible for the electrical and mechanical interface. The 2V forward voltage and 2-SMD gull wing package are identical. However, circuit current limiting resistors may require adjustment due to the reduced test current specification (10mA vs. 20mA) and increased luminous intensity (20mcd vs. 15mcd) of the substitute part.

Q: What is the impact of the lens transparency difference (diffused vs. clear)?

A: The main part features a diffused lens that scatters light over a wider area, while the substitute part has a clear lens that concentrates light output. This affects the visual appearance and light distribution pattern in the application. The main part's 50° viewing angle provides broader light visibility compared to the substitute's 28° viewing angle.

Q: Are there any moisture sensitivity considerations for storage and handling?

A: The main part carries MSL 1 (unlimited moisture sensitivity level), while the substitute part is MSL 2A (4 weeks). The substitute part requires moisture control during storage and has a 4-week floor life after moisture barrier bag opening. Standard moisture-controlled storage practices are required for the substitute part.

Q: What is the wavelength difference between the two parts?

A: The peak wavelengths differ by 2nm (585nm for the main part vs. 583nm for the substitute). Both wavelengths fall within the yellow spectrum range and are visually indistinguishable in indication applications.

Q: Is the substitute part suitable for high-brightness indication applications?

A: The substitute part delivers 20mcd luminous intensity compared to the main part's 15mcd, providing 33% higher brightness output. This makes the substitute part suitable for applications requiring increased visibility.
