WP7113YC Equivalent & Substitute Parts

Part Overview

The WP7113YC is an active, through-hole yellow LED indicator manufactured by Kingbright. This discrete component operates at 2.1V forward voltage with a 20mA test current and delivers 80 millicandela of luminous intensity through a clear, domed lens. The device is specified for 588nm dominant wavelength operation and features a 5mm T-1 3/4 form factor with radial leads.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers while accommodating application-specific requirements for brightness, viewing angle, and lens characteristics.

• Mounting Type: Through Hole
• Package / Case: Radial
• Voltage - Forward (Vf): 2.0V to 2.1V range
• Current - Test: 20mA
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Variable Parameters (Application-Dependent):

• Millicandela Rating: Brightness requirements may permit higher or lower values depending on circuit design
• Lens Transparency: Clear or diffused options available
• Lens Style: Domed or flat top configurations available
• Viewing Angle: Range from 20° to 100° depending on application requirements
• Wavelength - Dominant: 588nm to 590nm range acceptable for yellow indication

The identified substitute parts maintain electrical compatibility through matching forward voltage and test current specifications while offering alternative optical characteristics and brightness levels.

Parameter Comparison

Engineering Selection Recommendations

WP7113YC (Kingbright) - Primary Specification

The WP7113YC serves as the baseline reference. This component is active, ROHS3 compliant, and suitable for applications requiring narrow-angle yellow indication with moderate brightness output.

151051YS04000 (Würth Elektronik) - Moderate Brightness Alternative

The 151051YS04000 operates at 2V forward voltage, matching the lower end of the WP7113YC specification range. This substitute provides 450 millicandela output, representing a 5.6x brightness increase. The diffused lens and yellow lens color provide enhanced light distribution at 40° viewing angle. Maximum height of 8.95mm accommodates standard through-hole PCB layouts. This part is suitable for applications requiring increased visibility without extreme brightness levels.

OVLLY8C7 (TT Electronics/Optek Technology) - High Brightness Alternative

The OVLLY8C7 operates at 2V forward voltage and delivers 980 millicandela, representing a 12.25x brightness increase over the WP7113YC. The clear lens with flat-top geometry and 100° viewing angle provides wide-angle light distribution. Maximum height of 6.80mm offers compact form factor advantages. This part is suitable for applications requiring maximum brightness and wide viewing angle coverage.

All three parts maintain ROHS3 compliance and active product status, ensuring regulatory consistency and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 151051YS04000 directly replace the WP7113YC in existing circuit designs?

A: The 151051YS04000 operates at 2V forward voltage compared to the WP7113YC at 2.1V. Both parts accept 20mA test current. Circuit designs with fixed current-limiting resistors will experience approximately 5% lower voltage drop across the substitute part. Designs with voltage-regulated supplies will operate within normal tolerance. The diffused lens and yellow lens color alter light distribution characteristics compared to the clear lens of the WP7113YC.

Q: What are the optical differences between the three substitute options?

A: The WP7113YC provides narrow-angle indication at 20° with 80 millicandela through a clear lens. The 151051YS04000 expands the viewing angle to 40° with 450 millicandela through a diffused yellow lens, suitable for wider visibility requirements. The OVLLY8C7 provides the widest viewing angle at 100° with 980 millicandela through a clear lens, suitable for applications requiring maximum brightness and omnidirectional visibility.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All three parts feature radial through-hole packages compatible with standard PCB layouts. The WP7113YC and OVLLY8C7 both specify 5mm lens size, while the 151051YS04000 specifies 4.90mm diameter. Maximum heights differ: WP7113YC at 8.60mm, 151051YS04000 at 8.95mm, and OVLLY8C7 at 6.80mm. Applications with height constraints should prioritize the OVLLY8C7. Applications with tight lens diameter tolerances should prioritize the WP7113YC or OVLLY8C7.

Q: Do all substitute parts meet the same regulatory requirements?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All parts carry moisture sensitivity level 1 (unlimited). Regulatory compliance is equivalent across all options.

Q: What wavelength differences exist between the parts?

A: The WP7113YC specifies 588nm dominant wavelength. The 151051YS04000 specifies 590nm, and the OVLLY8C7 specifies 589nm. These wavelengths fall within the yellow spectrum range and are visually indistinguishable for indication applications. The differences reflect manufacturing variations across suppliers rather than intentional spectral targeting.
