WP7113SET Equivalent & Substitute Parts Reference

Part Overview

The WP7113SET is an orange LED indicator manufactured by Kingbright, designed for through-hole mounting applications. This T-1 3/4 (5mm) discrete LED operates at 2V forward voltage with a 2200mcd brightness rating and 20° viewing angle. The component is Active status and RoHS3 compliant, suitable for standard indication circuits requiring orange wavelength output at 601nm dominant wavelength.

Substitute parts are identified to address inventory availability, alternative sourcing requirements, or specific application parameter needs while maintaining functional compatibility within the T-1 3/4 through-hole LED category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WP7113SET are identified based on strict parameter compatibility within the through-hole LED category. The substitution logic is based on the following criteria:

Primary Compatibility Requirements:

• Mounting Type: Through Hole Radial (mechanical fit)
• Lens Size: T-1 3/4 (5mm) package
• Voltage - Forward (Vf): Range 1.9V to 2V (circuit compatibility)
• Current - Test: 20mA (standard operating condition)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Product Status: Active (supply continuity)

Secondary Consideration Parameters:

• Millicandela Rating: Brightness intensity (application-dependent)
• Viewing Angle: Light distribution (application-dependent)
• Wavelength - Dominant: Color specification (application-dependent)

The identified substitutes meet the primary compatibility requirements. Differences in brightness (mcd), viewing angle, and wavelength represent parameter variations that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

SLI-580DT3F (Orange LED): This Rohm Semiconductor part maintains orange color specification (605nm dominant wavelength) and is mechanically compatible with T-1 3/4 through-hole mounting. Forward voltage is 1.9V, requiring circuit resistor recalculation compared to the 2V WP7113SET. Brightness is rated at 5000mcd versus 2200mcd, representing increased intensity. Viewing angle is 10° versus 20°, indicating narrower light distribution. Both parts are Active status, ROHS3 compliant, and have unlimited moisture sensitivity rating. Selection is appropriate where higher brightness and narrower viewing angle are acceptable.

SLI-580YT3F (Yellow LED): This Rohm Semiconductor part differs in color specification (587nm dominant wavelength, yellow versus orange). All other mechanical and electrical parameters align with primary compatibility requirements: T-1 3/4 through-hole mounting, 1.9V forward voltage, 20mA test current, Active status, and ROHS3 compliance. Selection is appropriate only where yellow color output is functionally equivalent to orange in the application circuit.

Both substitutes are Active status products with established supply availability and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can SLI-580DT3F directly replace WP7113SET without circuit modification?

A: Mechanical and mounting compatibility is direct. Electrical circuit modification is required due to forward voltage difference (1.9V versus 2V). Current-limiting resistor values must be recalculated for the 0.1V difference to maintain 20mA test current operation.

Q: What is the impact of the 5000mcd brightness rating on SLI-580DT3F compared to 2200mcd on WP7113SET?

A: The SLI-580DT3F provides 2.27 times greater light intensity at the same 20mA test current. Application circuits must evaluate whether this increased brightness is acceptable or requires current reduction through resistor adjustment.

Q: Why does SLI-580DT3F have a 10° viewing angle versus 20° on WP7113SET?

A: Viewing angle is determined by lens design and internal LED geometry. The narrower 10° angle concentrates light output in a smaller cone, resulting in higher intensity in the central viewing direction but reduced visibility at off-axis angles.

Q: Is SLI-580YT3F suitable as a substitute for orange indication applications?

A: SLI-580YT3F is yellow (587nm) rather than orange (601nm). Substitution is appropriate only where application requirements permit yellow color output. Visual perception and circuit logic acceptance of yellow versus orange must be confirmed.

Q: Are all three parts RoHS3 compliant?

A: Yes. WP7113SET, SLI-580DT3F, and SLI-580YT3F are all ROHS3 compliant with REACH Unaffected status and unlimited moisture sensitivity rating (MSL 1).

Q: What is the height difference between WP7113SET and the Rohm substitutes?

A: WP7113SET maximum height is 8.60mm. Both SLI-580DT3F and SLI-580YT3F have maximum height of 8.70mm, a 0.10mm difference. This is within typical PCB assembly tolerances for through-hole components.

Q: Can circuit design accommodate both 2V and 1.9V forward voltage LEDs?

A: Circuit resistor values are calculated based on supply voltage, forward voltage, and desired test current. A 0.1V difference requires resistor recalculation. Designs with adjustable current-limiting resistors can accommodate both specifications.
