LED Circuit Board Indicator WP73EK/GDA Equivalent & Substitute Parts

Part Overview

The WP73EK/GDA is an active LED circuit board indicator manufactured by Kingbright, designed for through-hole, right-angle mounting applications. This single green diffused LED features a 4.80mm domed lens and operates at 2V with 25mA current consumption. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial circuit board applications. Substitute parts are identified based on functional equivalence in green LED indicator applications with compatible mounting and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WP73EK/GDA are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Color: Green LED indicator
• Configuration: Single LED element
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Product Status: Active
• Compliance: ROHS3 Compliant, REACH Unaffected

Secondary Compatibility Parameters:

• Voltage Rating: 2V to 2.2V operating range
• Current: 20mA to 25mA operating range
• Millicandela Rating: 30mcd to 34mcd brightness range
• Viewing Angle: 50° to 60° acceptable range
• Wavelength - Peak: 563nm to 568nm green spectrum range

The substitute part 5505205F from Dialight meets these criteria with minor variations in lens diameter (5mm vs 4.80mm) and electrical parameters within acceptable tolerance ranges for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Both the WP73EK/GDA and 5505205F are active products with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

WP73EK/GDA Selection Basis:

• Primary choice for applications requiring 4.80mm lens diameter specification
• 60° viewing angle provides wider light distribution
• 25mA current rating supports higher brightness applications
• 2V nominal voltage rating

5505205F Selection Basis:

• Alternative for applications accommodating 5mm lens diameter (T-1 3/4 standard package)
• 50° viewing angle suitable for focused indicator applications
• 20mA current rating reduces power consumption
• 2.2V nominal voltage rating compatible with standard logic supply voltages
• Higher millicandela rating (34mcd vs 30mcd) provides increased brightness at lower current

Both parts maintain identical compliance certifications and moisture sensitivity ratings, ensuring equivalent reliability in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can 5505205F directly replace WP73EK/GDA in existing circuit board designs?

A: Physical substitution requires PCB layout verification. The primary difference is lens diameter: WP73EK/GDA uses 4.80mm while 5505205F uses 5mm (T-1 3/4). Mounting hole diameter and right-angle lead configuration are compatible. Electrical parameters (voltage 2V vs 2.2V, current 25mA vs 20mA) fall within acceptable tolerance ranges for indicator applications.

Q: What are the brightness differences between these parts?

A: WP73EK/GDA provides 30mcd at 25mA and 2V. 5505205F provides 34mcd at 20mA and 2.2V. The Dialight part delivers higher brightness at lower current consumption, though wavelength differs slightly (563nm vs 568nm within green spectrum).

Q: Are viewing angle differences significant for indicator applications?

A: WP73EK/GDA offers 60° viewing angle versus 5505205F at 50°. The 10° difference affects light distribution pattern. Select 60° for applications requiring wider visibility; select 50° for focused indicator applications or when light concentration is preferred.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both WP73EK/GDA and 5505205F are ROHS3 compliant and REACH unaffected, meeting current EU and international regulatory standards for electronic components.

Q: What is the impact of lens size difference on mechanical fit?

A: The 4.80mm versus 5mm lens diameter difference affects bezel clearance and visual appearance. Verify PCB mounting hole diameter and panel cutout dimensions before substitution. Both parts use identical through-hole, right-angle mounting configuration.

Q: Can I use 5505205F in a 2V circuit designed for WP73EK/GDA?

A: The 2.2V rating of 5505205F is compatible with 2V nominal circuits. Verify actual circuit voltage supply and current limiting resistor values. The 5mA current reduction (25mA to 20mA) may require resistor adjustment to maintain desired brightness.
