WP793ED Orange Diffused LED 8mm Through-Hole Equivalent & Substitute Parts

Part Overview

The WP793ED is an orange diffused LED manufactured by Kingbright, designed for indication applications in through-hole mounting configurations. This Active product operates at 2V forward voltage with a 60mcd brightness rating and features an 8mm round domed lens with 30° viewing angle. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter ranges for LED indication components. Substitution becomes necessary due to inventory availability, supply chain optimization, or design flexibility requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WP793ED are identified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Mounting Type: Through Hole (radial configuration)
• Package / Case: Radial
• Lens Transparency: Diffused
• Lens Style: Round with Domed Top
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): Range 1.8V to 2.1V
• Current - Test: Range 2mA to 20mA
• Viewing Angle: 30° to 60°
• Millicandela Rating: 1.1mcd to 60mcd

The three identified substitute parts (LTL-4251NLC, LTL-307AE, LTL-10253W) meet the core mechanical and compliance requirements. Variations in color, wavelength, lens size, and brightness are documented to enable informed selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

LTL-307AE (Lite-On Inc.) provides the closest electrical performance match to WP793ED. Both components operate at 20mA test current and deliver comparable brightness levels (40mcd vs 60mcd). Forward voltage differential is minimal (2.1V vs 2V). The primary design consideration is lens size reduction (5mm vs 8mm) and lens transparency change (Clear vs Diffused). This substitute maintains ROHS3 compliance and Active product status.

LTL-10253W (Lite-On Inc.) operates at reduced current (10mA vs 20mA) with significantly lower brightness output (12.6mcd vs 60mcd). Lens size is reduced to 4.75mm diameter. Forward voltage is 2.1V. This substitute is suitable for applications where lower brightness and reduced power consumption are acceptable. ROHS3 compliance and Active status are maintained.

LTL-4251NLC (Lite-On Inc.) represents the most significant departure from WP793ED specifications. Operating current is reduced to 2mA with minimal brightness output (1.1mcd). Lens size is 3.00mm diameter. Forward voltage is 1.8V. This substitute is applicable only in low-power indicator applications where brightness requirements are minimal. ROHS3 compliance is maintained; however, REACH Status is listed as Affected (compared to REACH Unaffected for WP793ED).

All substitute parts maintain Through Hole mounting configuration, Radial package type, and MSL 1 rating. Selection should be based on specific application requirements for brightness, viewing angle, lens size, and power consumption constraints.

Frequently Asked Questions (FAQ)

Q: Can LTL-307AE directly replace WP793ED in all applications?

A: LTL-307AE is mechanically and electrically compatible for through-hole mounting applications. Key differences include lens size (5mm vs 8mm), lens transparency (Clear vs Diffused), and brightness (40mcd vs 60mcd). Applications requiring the specific 8mm diffused lens or 60mcd brightness output require evaluation before substitution.

Q: What is the primary difference between LTL-10253W and LTL-4251NLC?

A: Both are yellow LEDs from Lite-On Inc. with diffused lenses. LTL-10253W operates at 10mA with 12.6mcd brightness and 4.75mm lens diameter. LTL-4251NLC operates at 2mA with 1.1mcd brightness and 3.00mm lens diameter. LTL-10253W is suitable for standard indication applications; LTL-4251NLC is for ultra-low-power applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. WP793ED and all three substitute parts (LTL-4251NLC, LTL-307AE, LTL-10253W) are ROHS3 compliant. LTL-4251NLC carries REACH Affected status, while WP793ED is REACH Unaffected. Verify REACH compliance requirements for your specific application.

Q: What mounting considerations apply when substituting WP793ED with smaller lens diameter alternatives?

A: All substitute parts maintain Through Hole radial mounting configuration compatible with standard PCB footprints. Physical lens diameter reduction (8mm to 3-5mm) may affect visual appearance and light distribution in the application. Verify that reduced lens size does not impact aesthetic or functional requirements.

Q: Can WP793ED be substituted in applications requiring 30° viewing angle?

A: WP793ED specifies 30° viewing angle. LTL-307AE provides 40° viewing angle (closest match). LTL-10253W and LTL-4251NLC both provide 60° viewing angle (wider distribution). Applications with strict 30° viewing angle requirements should prioritize LTL-307AE or confirm that wider viewing angles are acceptable.

Q: What is the voltage compatibility range for substitution?

A: WP793ED operates at 2V forward voltage. Substitute parts operate at 1.8V (LTL-4251NLC) to 2.1V (LTL-307AE, LTL-10253W). Circuit designs must accommodate this 0.3V maximum variance. Verify that current-limiting resistor calculations remain valid across this voltage range.
