Equivalent & Substitute Parts for WP1503EB/2ID

Part Overview

The WP1503EB/2ID is a dual-level red LED circuit board indicator manufactured by Kingbright. This through-hole, right-angle mounted component operates at 2V with a 20mA current rating and features a 5mm diffused, tinted lens with domed top. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when inventory constraints require alternative procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WP1503EB/2ID is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Configuration: 2 High (dual-level LED)
• Color: Red (x 2)
• Voltage Rating: 2V
• Current: 20mA
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole, Right Angle
• Viewing Angle: 60°

Allowable Variation Parameters:

• Wavelength - Peak: 627nm to 635nm (red spectrum range)
• Millicandela Rating: 40mcd to 50mcd (luminous intensity tolerance)
• Manufacturer: Different manufacturers permitted
• Packaging: Different packaging formats permitted

The substitute part SSF-LXHM250IID from Lumex Opto/Components Inc. meets all mandatory matching parameters and falls within allowable variation ranges for wavelength and millicandela rating.

Parameter Comparison

Engineering Selection Recommendations

Both the WP1503EB/2ID and SSF-LXHM250IID are Active product status components with full RoHS3 compliance and REACH unaffected status, making them suitable for equivalent substitution in circuit board indicator applications.

The primary distinction between these parts is the wavelength specification: the Kingbright WP1503EB/2ID operates at 627nm (pure red), while the Lumex SSF-LXHM250IID operates at 635nm (red-orange spectrum). Both wavelengths fall within the red LED classification and are visually indistinguishable in typical circuit board indicator applications.

The Kingbright part provides 50mcd luminous intensity, while the Lumex substitute provides 40mcd. This 10mcd difference represents a 20% reduction in brightness and should be evaluated based on specific application requirements for indicator visibility.

Both components share identical electrical specifications (2V, 20mA), mechanical form factors (5mm through-hole right-angle mount), and regulatory compliance certifications. Selection between these parts should be based on availability, lead time, and the specific brightness requirement of the application.

Frequently Asked Questions (FAQ)

Q: Can SSF-LXHM250IID be used as a direct replacement for WP1503EB/2ID?

A: Yes. Both parts share identical voltage, current, mounting type, lens configuration, and viewing angle specifications. The wavelength difference (627nm vs 635nm) and brightness difference (50mcd vs 40mcd) are within acceptable substitution parameters for circuit board indicator applications.

Q: What is the difference between 627nm and 635nm wavelength?

A: Both wavelengths are classified as red LEDs. The 627nm wavelength (Kingbright) produces a pure red appearance, while 635nm (Lumex) produces a red-orange appearance. The color difference is subtle and typically imperceptible in standard circuit board indicator applications.

Q: Does the 10mcd brightness difference affect circuit board indicator performance?

A: The Lumex part provides 40mcd compared to the Kingbright part's 50mcd. This represents a 20% reduction in luminous intensity. For applications where indicator visibility is critical, this difference should be evaluated against specific brightness requirements. For standard circuit board indicator applications, this difference is typically acceptable.

Q: Are both parts RoHS3 compliant?

A: Yes. Both WP1503EB/2ID and SSF-LXHM250IID are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference in packaging between these parts?

A: The Kingbright WP1503EB/2ID is packaged in standard format, while the Lumex SSF-LXHM250IID is packaged in Bulk format. Both are suitable for through-hole assembly processes.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts have identical mechanical dimensions (5mm, T-1 3/4), identical mounting type (through-hole, right-angle), and identical electrical specifications (2V, 20mA). They are mechanically and electrically interchangeable on the same printed circuit board.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
