TLCR6800 Equivalent & Substitute Parts

Part Overview

The TLCR6800 is a red LED indication component manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting applications. This 5mm radial LED operates at 2.1V forward voltage with a 35000mcd brightness rating and 616nm dominant wavelength. The component is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the TLCR6800 becomes unavailable, when alternative brightness or viewing angle characteristics are required for specific circuit designs, or when sourcing from alternative manufacturers is preferred for supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the TLCR6800 is determined by the following criteria:

Primary Compatibility Parameters:

Color: Red
Lens Transparency: Clear
Mounting Type: Through Hole
Package / Case: Radial
Wavelength range: 616nm to 660nm (dominant wavelength)

Secondary Variation Parameters:

Voltage - Forward (Vf): 1.7V to 2.2V acceptable range
Current - Test: 20mA to 50mA
Millicandela Rating: 50mcd to 2500mcd
Viewing Angle: 8° to 30°
Height (Max): 8.60mm to 12.44mm

Substitute parts must maintain red color, clear lens transparency, through-hole radial mounting, and operate within the specified wavelength range. Variations in brightness, viewing angle, forward voltage, and physical height are acceptable based on circuit design requirements and mechanical constraints.

Engineering Selection Recommendations

Active Status Substitutes (Preferred): HLMP-D105, LTL2R3KEK, LTL2R3KRK, SSL-LX5093SRC/DV, SSL-LX5093XRC/4, WP1503EC, and WP7113EC are all in active product status with ROHS3 compliance. These parts are suitable for new designs and ongoing production requirements.

Obsolete Status Substitutes (Limited Use): MV3750 and SSL-LX5093SRC/DU are obsolete products. These parts may be used only when existing inventory is available and no active alternatives meet design requirements. Obsolete parts are not recommended for new designs.

Compliance Considerations: All active substitute parts maintain ROHS3 compliance matching the TLCR6800. The TLCR6800 and all active substitutes carry unlimited moisture sensitivity rating (MSL 1), indicating no special storage or handling requirements.

Forward Voltage Compatibility: The TLCR6800 operates at 2.1V typical forward voltage. Substitutes range from 1.7V to 2.2V. Circuit designs using current-limiting resistors will accommodate this variation. Direct voltage-source applications require verification that the selected substitute's forward voltage is compatible with the power supply design.

Brightness and Viewing Angle Trade-offs: The TLCR6800 provides 35000mcd brightness with an 8° viewing angle. Substitutes offer lower brightness ratings (50mcd to 2500mcd) with wider viewing angles (20° to 30°). Selection depends on application requirements for brightness intensity and light distribution pattern.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different forward voltage than the TLCR6800?

A: Yes, within the range of 1.7V to 2.2V. Circuit designs using current-limiting resistors will function correctly with forward voltage variations. Verify that your power supply and resistor values are compatible with the selected substitute's forward voltage specification.

Q: What is the difference between the TLCR6800's 8° viewing angle and the wider angles offered by substitutes?

A: Viewing angle determines the light distribution pattern. The TLCR6800's 8° angle produces a narrow, concentrated light beam. Substitutes with 20° to 30° angles distribute light over a wider area. Select based on whether your application requires focused or dispersed illumination.

Q: Are obsolete parts like MV3750 and SSL-LX5093SRC/DU suitable for new designs?

A: No. Obsolete parts are not recommended for new designs. Use only when existing inventory is available and no active alternatives meet your requirements. For new designs, select from active status parts: HLMP-D105, LTL2R3KEK, LTL2R3KRK, SSL-LX5093SRC/DV, SSL-LX5093XRC/4, WP1503EC, or WP7113EC.

Q: How do I select between the Lumex SSL-LX5093 variants?

A: All three Lumex variants (SSL-LX5093SRC/DU, SSL-LX5093SRC/DV, SSL-LX5093XRC/4) share identical forward voltage (1.7V) and wavelength (660nm). They differ in brightness and viewing angle: SSL-LX5093SRC/DU provides 1200mcd at 30°, SSL-LX5093SRC/DV provides 1500mcd at 30°, and SSL-LX5093XRC/4 provides 2500mcd at 20°. Select based on required brightness and viewing angle for your application.

Q: Will the TLCR6800 substitute parts fit in the same PCB footprint?

A: All substitute parts use through-hole radial mounting with 5mm lens sizes. Physical heights vary from 8.60mm to 12.44mm. Verify that your PCB layout accommodates the selected substitute's maximum height specification.

Q: What is the difference between the Kingbright WP1503EC and WP7113EC?

A: Both parts share identical forward voltage (2V), wavelength (627nm), and height (8.60mm). WP1503EC provides 50mcd brightness at 30° viewing angle, while WP7113EC provides 100mcd brightness at 20° viewing angle. Select based on required brightness intensity and viewing angle for your application.
