Key Parameters

Substitute Part Grouping Explanation

Substitution of the QTLP9134 is based on the following critical parameters that must align between the main part and substitute components:

• Color and Wavelength: Green LED with peak wavelength at 565nm
• Electrical Characteristics: Forward voltage of 2.1V and test current compatibility
• Mounting Configuration: Through-hole axial mounting with flat leads
• Lens Type: Diffused or clear lens options acceptable for indication applications
• Physical Form Factor: T-3/4 subminiature package dimensions
• Compliance: REACH Unaffected status maintained

The HLMP-6505 from Broadcom Limited qualifies as a substitute based on matching color, forward voltage, mounting type, and package configuration. While certain parameters differ (lens transparency, millicandela rating, viewing angle), these variations remain within acceptable tolerances for green LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-6505 is an active product from Broadcom Limited and serves as the primary substitute for the obsolete QTLP9134. Both components share identical forward voltage (2.1V) and peak wavelength (565nm), ensuring electrical compatibility in green LED indication circuits.

The HLMP-6505 demonstrates superior availability with 960,200 pieces in stock compared to 956 pieces of the QTLP9134. The substitute component maintains REACH Unaffected compliance status, matching the regulatory profile of the original part.

Physical dimensions remain compatible within standard PCB layout tolerances. The HLMP-6505 operates at a lower test current (10mA versus 20mA) and delivers higher luminous intensity (40mcd versus 5mcd), characteristics that benefit long-term circuit reliability and optical performance in indication applications.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-6505 directly replace the QTLP9134 in existing designs?

A: Yes. Both components share identical forward voltage (2.1V), peak wavelength (565nm), and axial through-hole mounting configuration. Physical dimensions are compatible within standard PCB tolerances.

Q: What are the differences in lens characteristics?

A: The QTLP9134 features a diffused lens, while the HLMP-6505 has a clear lens. The HLMP-6505 delivers 40mcd compared to 5mcd for the QTLP9134, with a narrower viewing angle (28° versus 50°). These differences affect light distribution but do not prevent substitution in indication applications.

Q: Are there compliance or regulatory concerns with substitution?

A: No. Both components maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the impact of different test currents?

A: The HLMP-6505 operates at 10mA test current versus 20mA for the QTLP9134. Circuit designs should accommodate this difference through appropriate current-limiting resistor selection to maintain desired luminous output.

Q: How do the physical dimensions compare?

A: The HLMP-6505 is slightly shorter (2.92mm maximum height versus 3.00mm) and has a marginally smaller lens diameter (1.91mm versus 2mm). These variations fall within standard PCB assembly tolerances and do not affect mechanical fit in through-hole applications.
