WP7113LSRD Equivalent & Substitute Parts

Part Overview

The WP7113LSRD is a red diffused LED indicator manufactured by Kingbright, designed for through-hole mounting applications. This component features a 5mm T-1 3/4 lens form factor with a dominant wavelength of 640nm and typical forward voltage of 1.65V at 2mA test current. The product is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility within standard LED indicator applications. Substitute parts must preserve the through-hole radial mounting configuration, diffused red lens characteristics, and T-1 3/4 package form factor while accommodating variations in electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WP7113LSRD is determined by strict adherence to the following mandatory parameters:

Mechanical Compatibility Requirements:

• Lens size must be 5mm, T-1 3/4 form factor
• Mounting type must be through-hole radial configuration
• Lens transparency must be diffused
• Color must be red

Electrical Compatibility Considerations:

• Forward voltage (Vf) range: 1.65V to 2.0V acceptable for standard indicator circuits
• Test current: 2mA to 20mA range accommodates various circuit designs
• Wavelength dominant: 626nm to 640nm range maintains red color perception
• Millicandela rating: 8mcd to 700mcd range supports different brightness requirements
• Viewing angle: 30° to 65° range acceptable for indicator applications

Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required
• Moisture sensitivity level 1 or 2A acceptable

All substitute parts listed maintain the core mechanical form factor and through-hole radial package while operating within extended electrical parameter ranges suitable for LED indicator circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes for Direct Replacement:

The HLMP-3762 and HLMP-3762-G00B2 (Broadcom Limited) represent the closest electrical and mechanical equivalents to the WP7113LSRD. Both maintain the 5mm T-1 3/4 diffused red lens configuration with through-hole radial mounting. The HLMP-3762 operates at 1.9V forward voltage with 10mA test current and 8.6mcd brightness, providing near-identical optical characteristics. The HLMP-3762-G00B2 variant offers right-angle mounting geometry for applications requiring board-level orientation adjustment. Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

Higher Brightness Alternatives:

The HLMP-EG55 series (HLMP-EG55-GK0DD, HLMP-EG55-HJ000, HLMP-EG55-JK0DU) provides increased luminous intensity ranging from 245mcd to 320mcd while maintaining the same mechanical form factor and through-hole radial package. These parts operate at 1.9V with 20mA test current and 55° viewing angle. Selection from this series is appropriate for applications requiring enhanced visibility or longer viewing distances.

Extended Brightness Range:

The SSL-LX5093SID (Lumex Opto/Components Inc.) delivers maximum brightness at 700mcd with 2.0V forward voltage and 20mA test current. This part maintains identical height (8.60mm) to the original WP7113LSRD and provides the widest viewing angle at 60°. Selection is appropriate for high-visibility indicator applications.

Lower Brightness Option:

The HLMP-WG02 (Broadcom Limited) operates at 26mcd with 1.9V forward voltage and 65° viewing angle. This part is suitable for applications where reduced brightness is required or where power consumption must be minimized. Moisture sensitivity level is 2A (4 weeks), requiring controlled storage conditions.

Compliance Status:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original WP7113LSRD specification. All parts are currently active products with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3762 directly replace WP7113LSRD in existing circuit designs?

A: The HLMP-3762 is mechanically and functionally compatible as a direct substitute. Both parts share identical 5mm T-1 3/4 through-hole radial package geometry and diffused red lens characteristics. The forward voltage increases from 1.65V to 1.9V, and test current increases from 2mA to 10mA. Circuit designs using current-limiting resistors will accommodate this voltage difference. Verify that the circuit's current-limiting resistor value is appropriate for the higher test current specification.

Q: What is the difference between HLMP-3762 and HLMP-3762-G00B2?

A: Both parts share identical electrical specifications (1.9V forward voltage, 10mA test current, 8.6mcd brightness). The primary difference is mounting orientation: HLMP-3762 is standard radial through-hole, while HLMP-3762-G00B2 is right-angle through-hole. Right-angle mounting positions the LED parallel to the circuit board surface, suitable for edge-mounted or board-level indicator applications. Standard radial mounting positions the LED perpendicular to the board.

Q: Why do substitute parts have higher forward voltage than WP7113LSRD?

A: The substitute parts operate at 1.9V to 2.0V forward voltage compared to the original 1.65V specification. This difference reflects manufacturing variations across different LED manufacturers and wavelength specifications. Red LEDs with peak wavelengths of 635nm to 636nm typically exhibit higher forward voltage than 640nm dominant wavelength devices. Circuit designs using series current-limiting resistors will automatically compensate for this voltage difference.

Q: Can I use HLMP-EG55-JK0DU as a direct replacement if brightness is not critical?

A: Yes, the HLMP-EG55-JK0DU is mechanically compatible and maintains the same 5mm T-1 3/4 through-hole radial package. However, this part operates at significantly higher brightness (320mcd versus 8mcd) and requires 20mA test current versus 2mA. If brightness reduction is required, use HLMP-WG02 (26mcd) or HLMP-3762 (8.6mcd) instead. The HLMP-EG55-JK0DU is appropriate only when increased visibility is desired.

Q: What is the height difference between WP7113LSRD and substitute parts?

A: The WP7113LSRD and SSL-LX5093SID both have maximum height of 8.60mm. The HLMP-3762 reaches 9.19mm maximum height, while HLMP-EG55 series parts reach 8.91mm. These height variations are within typical through-hole component tolerances and do not affect PCB layout compatibility. Verify clearance in applications with height-constrained enclosures.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected. The WP7113LSRD is also ROHS3 compliant. All parts meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of moisture sensitivity level differences?

A: The WP7113LSRD, HLMP-3762 series, HLMP-EG55 series, and SSL-LX5093SID all have moisture sensitivity level 1 (unlimited), meaning they can be stored indefinitely without moisture control. The HLMP-WG02 has moisture sensitivity level 2A (4 weeks), requiring controlled storage conditions and desiccant packaging. For applications with extended storage or high-humidity environments, select parts with MSL 1 rating.

Q: Can substitute parts be used in applications requiring 30° narrow viewing angle?

A: The WP7113LSRD provides 30° viewing angle, the narrowest among all listed parts. Substitute parts range from 55° to 65° viewing angle. If narrow viewing angle is critical for the application, the WP7113LSRD cannot be substituted. For applications where wider viewing angle is acceptable or beneficial, HLMP-3762 (60°), HLMP-EG55 series (55°), HLMP-WG02 (65°), or SSL-LX5093SID (60°) are suitable alternatives.
