LTW-2L3DV5S LED White Clear T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The LTW-2L3DV5S is an active white LED indication component manufactured by Lite-On Inc., designed for through-hole mounting applications. This discrete 3.3V radial LED features a clear, domed lens in a 5mm T-1 3/4 package format. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and consumer electronics applications. Substitute parts are identified when equivalent electrical characteristics and mechanical compatibility exist within the through-hole LED category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTW-2L3DV5S are qualified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Parameters:

• Color: White
• Lens Transparency: Clear
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Lens Size: 5mm, T-1 3/4 or 5.00mm Dia
• Voltage - Forward (Vf) Typical: 3.2V to 3.4V (±0.1V tolerance band)
• Current - Test: 20mA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Millicandela Rating: 3500mcd to 35000mcd (brightness variation acceptable for indication applications)
• Viewing Angle: 15° to 50° (application-dependent selection)
• Height (Max): 8.70mm to 12.10mm (PCB layout dependent)

All substitute parts maintain active product status and meet the same regulatory compliance standards as the main part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the LTW-2L3DV5S. Selection among substitutes depends on application-specific requirements:

334-15/X1C2-1UWA (Everlight Electronics): Forward voltage of 3.2V and 13500mcd brightness with 20° viewing angle. Reduced height (8.90mm) accommodates space-constrained PCB layouts. Warm white color variant available for applications requiring color temperature differentiation.

OVLEW1CB9 (TT Electronics/Optek Technology): Highest brightness rating at 35000mcd with 3.2V forward voltage and 15° narrow viewing angle. Minimum height (8.80mm) suitable for compact assemblies. Appropriate for applications requiring maximum luminous intensity in focused beam patterns.

SLX-LX5093UWC/C (Lumex Opto/Components Inc.): Forward voltage of 3.4V with 3500mcd brightness and 40° viewing angle. Minimum height (8.70mm) with moderate brightness and wide viewing angle. Suitable for general indication applications requiring balanced brightness and visibility range.

All parts are active products with confirmed inventory availability and meet identical regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can the LTW-2L3DV5S be directly replaced with any of these substitute parts?

A: Yes, all listed substitute parts are electrically and mechanically compatible. Forward voltage ranges from 3.2V to 3.4V, all operate at 20mA test current, and all use identical through-hole radial mounting with 5mm clear domed lenses. PCB layout and circuit design must accommodate the specified forward voltage of each substitute.

Q: What is the primary difference between these substitute parts?

A: The main differences are brightness (millicandela rating), viewing angle, and physical height. The 334-15/X1C2-1UWA offers highest brightness at 13500mcd; OVLEW1CB9 provides maximum brightness at 35000mcd with narrow viewing angle; SLX-LX5093UWC/C delivers moderate brightness at 3500mcd with wide viewing angle. Height varies from 8.70mm to 12.10mm.

Q: Are there color differences between substitutes?

A: The 334-15/X1C2-1UWA is specified as warm white, while the LTW-2L3DV5S, OVLEW1CB9, and SLX-LX5093UWC/C are standard white. Color perception differences may be visible in side-by-side comparison.

Q: Do all substitutes fit the same PCB footprint?

A: All parts use identical through-hole radial mounting with 5mm T-1 3/4 or 5.00mm package formats. Physical height varies from 8.70mm to 12.10mm; verify PCB clearance requirements for your specific application.

Q: What forward voltage should I use for circuit design?

A: Design for the specific forward voltage of your selected part: 3.2V (Everlight, Optek), 3.3V (Lite-On), or 3.4V (Lumex). Current-limiting resistor calculations must account for the chosen part's forward voltage to maintain 20mA test current.

Q: Are all parts RoHS and MSL compliant?

A: Yes, all parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the original LTW-2L3DV5S specifications.
