QTLP601CEBTR Equivalent & Substitute Parts

Part Overview

The QTLP601CEBTR is a blue LED indication component manufactured by Everlight Electronics Co Ltd, designed for surface mount applications in the 0603 (1608 Metric) package format. This discrete LED operates at a forward voltage of 3.15V with a dominant wavelength of 473nm and provides 17 millicandela of light output at 5mA test current. The component features a clear, colorless lens with a rectangular flat-top design and 120° viewing angle.

The QTLP601CEBTR is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QTLP601CEBTR is determined by strict alignment of the following critical parameters:

Package Compatibility: The substitute part must use the 0603 (1608 Metric) surface mount package to ensure mechanical fit on printed circuit boards designed for the original component.

Optical Characteristics: The substitute must be a blue LED with clear, colorless lens and rectangular flat-top lens style to maintain visual indication consistency and optical performance in the application.

Electrical Parameters: Forward voltage, test current, millicandela rating, wavelength, and viewing angle must fall within acceptable ranges for the application circuit. The substitute LSM0603463V operates at 3V forward voltage (compared to 3.15V) with 20mcd output at 20mA test current and 469nm dominant wavelength (compared to 473nm), representing minor variations within the blue LED spectrum.

Regulatory Compliance: Both components must maintain ROHS3 compliance and EAR99 ECCN classification for unrestricted use.

Physical Dimensions: Substitute parts must match the 1.60mm L x 0.80mm W footprint and maintain compatible height specifications for PCB assembly.

Parameter Comparison

Engineering Selection Recommendations

The LSM0603463V from Visual Communications Company - VCC is an active production substitute for the obsolete QTLP601CEBTR. Both components maintain ROHS3 compliance and EAR99 ECCN classification, ensuring regulatory alignment for applications requiring these certifications.

The LSM0603463V offers the advantage of active product status with documented inventory availability, eliminating supply chain risk associated with the obsolete QTLP601CEBTR. The substitute maintains identical package dimensions, mounting type, and optical lens characteristics required for direct PCB compatibility.

Electrical parameter variations between the components are minor: forward voltage differs by 0.15V (3.15V to 3V), and wavelength differs by 4nm (473nm to 469nm), both within the blue LED spectrum. The substitute provides higher millicandela output (20mcd versus 17mcd) at a higher test current (20mA versus 5mA).

Physical height is reduced from 0.60mm to 0.50mm maximum, which presents no compatibility constraint for standard PCB assembly processes. Moisture sensitivity level increases from MSL 2 to MSL 3, requiring adherence to appropriate storage and handling protocols during component storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the LSM0603463V be used as a direct replacement for the QTLP601CEBTR without PCB modifications?

A: Yes. Both components use the identical 0603 (1608 Metric) surface mount package with matching 1.60mm L x 0.80mm W footprint dimensions. The LSM0603463V maximum height of 0.50mm is lower than the QTLP601CEBTR at 0.60mm, presenting no assembly or clearance issues. No PCB layout modifications are required.

Q: What are the electrical differences between these components?

A: The LSM0603463V operates at 3V forward voltage compared to the QTLP601CEBTR at 3.15V, a difference of 0.15V. The dominant wavelength is 469nm versus 473nm, a 4nm difference within the blue LED spectrum. The substitute provides 20mcd output at 20mA test current, compared to 17mcd at 5mA for the original component. These variations are within standard blue LED performance ranges.

Q: Are there compliance or certification differences?

A: Both components are ROHS3 compliant and classified as EAR99 for export control purposes. The LSM0603463V carries REACH Unaffected status. Moisture sensitivity level differs: QTLP601CEBTR is MSL 2 (1 Year storage), while LSM0603463V is MSL 3 (168 Hours storage). Appropriate moisture control measures must be implemented during component storage and assembly for the substitute part.

Q: Why is the QTLP601CEBTR classified as obsolete?

A: The QTLP601CEBTR is listed as obsolete by the manufacturer. The LSM0603463V is an active production component from Visual Communications Company - VCC, ensuring ongoing availability and supply chain continuity.

Q: What is the optical performance difference?

A: Both components feature identical lens characteristics: colorless, clear lens with rectangular flat-top design and 120° viewing angle. The millicandela rating increases from 17mcd to 20mcd with the substitute, providing slightly higher light output intensity.
