QTLP600CEBTR Blue LED 0603 SMD Equivalent & Substitute Parts

Part Overview

The QTLP600CEBTR is a blue LED indication component manufactured by Everlight Electronics Co Ltd in 0603 (1608 Metric) surface mount package. This discrete LED operates at 2.8V forward voltage with a 25mcd brightness rating and 465nm peak wavelength. The product is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across electrical specifications, mechanical dimensions, and mounting characteristics to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the QTLP600CEBTR are identified based on strict alignment with the following critical parameters:

Electrical Compatibility Requirements:

• Color: Blue (465nm wavelength range)
• Forward Voltage (Vf): 2.8V nominal
• Test Current: 5mA operating point
• Lens Transparency: Clear

Mechanical Compatibility Requirements:

• Package Type: 0603 (1608 Metric) surface mount
• Mounting Type: Surface mount
• Physical Dimensions: 1.60mm L x 0.80mm W
• Height: Maximum 0.80mm

Regulatory Compliance:

• RoHS3 Compliant status

The LTST-C193TBKT-5A from LITEON meets all critical electrical and mechanical parameters, enabling direct substitution in circuit applications. Variations in millicandela rating (15mcd vs. 25mcd) and viewing angle (130° vs. 100°) represent acceptable parameter ranges within the 0603 blue LED category and do not preclude substitution where the application tolerates these differences.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LTST-C193TBKT-5A (LITEON)

The LTST-C193TBKT-5A is the qualified substitute for QTLP600CEBTR applications. Selection rationale:

1. Electrical Equivalence: Identical forward voltage (2.8V) and test current (5mA) ensure direct circuit compatibility without redesign.

2. Mechanical Equivalence: Identical 0603 package dimensions and surface mount configuration enable direct PCB footprint replacement.

3. Regulatory Compliance: Both components maintain ROHS3 compliance status, satisfying environmental and regulatory requirements.

4. Production Status: LTST-C193TBKT-5A is active production with 128,100 units in stock, providing supply continuity for the obsolete QTLP600CEBTR.

5. Physical Characteristics: The substitute's reduced maximum height (0.45mm vs. 0.80mm) presents no compatibility issues and may improve clearance in space-constrained layouts.

6. Optical Characteristics: The wider viewing angle (130° vs. 100°) and slightly lower brightness (15mcd vs. 25mcd) are acceptable for indication applications where the original 25mcd specification was not a critical design constraint. Applications requiring the original 25mcd brightness must evaluate the brightness reduction against specific visibility requirements.

Frequently Asked Questions (FAQ)

Q1: Can LTST-C193TBKT-5A directly replace QTLP600CEBTR without PCB modification?

A: Yes. Both components share identical 0603 (1608 Metric) package dimensions (1.60mm L x 0.80mm W) and surface mount configuration. No PCB footprint changes are required.

Q2: Are the forward voltage specifications identical?

A: Yes. Both components operate at 2.8V typical forward voltage and 5mA test current, ensuring circuit compatibility without driver circuit modification.

Q3: What is the brightness difference between these parts?

A: QTLP600CEBTR is rated at 25mcd while LTST-C193TBKT-5A is rated at 15mcd. The substitute provides 60% of the original brightness. For indication applications (status LEDs, power indicators), this reduction is typically acceptable. Applications requiring full 25mcd brightness must evaluate alternative parts.

Q4: Does the viewing angle difference affect substitution?

A: LTST-C193TBKT-5A provides a wider viewing angle (130° vs. 100°), which is advantageous for applications requiring visibility across a broader range of viewing positions. This represents an improvement over the original specification.

Q5: Are both components RoHS compliant?

A: Yes. Both QTLP600CEBTR and LTST-C193TBKT-5A are ROHS3 compliant, meeting environmental and regulatory requirements.

Q6: What is the height difference and does it matter?

A: LTST-C193TBKT-5A has a maximum height of 0.45mm compared to 0.80mm for QTLP600CEBTR. The lower profile of the substitute improves clearance in space-constrained designs and presents no compatibility issues.

Q7: Why is QTLP600CEBTR classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. LTST-C193TBKT-5A is active production, ensuring long-term supply availability for new designs and ongoing support of existing applications.

Q8: Are there packaging differences between these parts?

A: QTLP600CEBTR is supplied in standard packaging, while LTST-C193TBKT-5A is available in Cut Tape (CT) and Digi-Reel® formats, providing flexibility in procurement quantities and handling methods.
