Key Parameters

Substitute Part Grouping Explanation

Substitution for the QTLP600C3TR is determined by strict alignment of the following critical parameters:

• Package / Case: 0603 (1608 Metric) surface mount package
• Color: Yellow
• Wavelength - Dominant: 590nm
• Wavelength - Peak: 585nm
• Voltage - Forward (Vf) (Typ): 2V
• Current - Test: 20mA
• Millicandela Rating: 9mcd
• Viewing Angle: 100°
• Lens Color: Colorless
• Lens Transparency: Clear
• Lens Style: Rectangle with Flat Top
• Lens Size: 1.20mm x 0.80mm
• Mounting Type: Surface Mount

A substitute part must match all of these parameters to ensure functional and mechanical compatibility within the original application circuit and PCB layout.

Parameter Comparison

Engineering Selection Recommendations

The QTLP600C3TR is classified as obsolete. When selecting substitute components, prioritize parts with identical electrical characteristics (2V forward voltage, 20mA test current, 590nm dominant wavelength) and mechanical specifications (0603 package, 9mcd brightness, 100° viewing angle, rectangular flat-top lens).

Compliance certifications including REACH Unaffected status and EAR99 ECCN classification should be verified for substitute parts to maintain regulatory alignment with the original component specification.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the QTLP600C3TR?

A: A valid substitute must match all specified parameters: 0603 (1608 Metric) package, yellow color, 590nm dominant wavelength, 2V forward voltage, 20mA test current, 9mcd brightness, 100° viewing angle, colorless clear lens, rectangular flat-top lens style, 1.20mm x 0.80mm lens size, and 0.80mm maximum height.

Q: Can I use a different package size as a substitute?

A: No. The 0603 (1608 Metric) surface mount package is a critical mechanical specification. Different package sizes will not fit the original PCB footprint and require circuit board redesign.

Q: Are there any compatibility concerns with MSL (Moisture Sensitivity Level)?

A: The QTLP600C3TR has MSL 2 (1 Year) rating. Substitute parts must maintain the same MSL classification to ensure equivalent moisture handling and storage requirements.

Q: What if I cannot find an exact match for all parameters?

A: All parameters listed in the Key Parameters table are mandatory for substitution. Deviations in wavelength, brightness, viewing angle, lens configuration, or electrical characteristics will alter circuit performance and visual indication behavior.
