WP813ID Red Diffused 10mm Through-Hole LED Equivalent & Substitute Parts

Part Overview

The WP813ID is an active production red diffused LED indicator manufactured by Kingbright, designed for discrete indication applications in through-hole mounting configurations. This 10mm diameter component operates at 2V forward voltage with a 20mA test current and delivers 80mcd luminous intensity at a 617nm dominant wavelength. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and consumer electronics applications.

Substitute parts are identified when equivalent electrical performance parameters and mechanical compatibility allow direct functional replacement within the same application circuit, subject to viewing angle and luminous intensity tolerances specific to the end-use requirement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WP813ID are identified based on strict electrical and mechanical parameter alignment. The substitution logic is structured as follows:

Primary Substitution Criteria (Must Match):

• Voltage - Forward (Vf): 2V nominal
• Color: Red
• Lens Transparency: Diffused
• RoHS Status: ROHS3 Compliant
• Mounting Type: Through Hole (for mechanical compatibility)

Secondary Compatibility Parameters (Allowable Variance):

• Current - Test: 20-30mA range acceptable within circuit design margins
• Millicandela Rating: 5-80mcd range acceptable depending on application brightness requirements
• Viewing Angle: 30-60° range acceptable for general indication applications
• Lens Size: Variance acceptable only if mechanical mounting envelope permits

Non-Substitutable Parameters:

• Lens Size (10mm) is critical for panel cutout and housing fit; parts with different lens diameters (3mm, 4mm) are mechanically incompatible with WP813ID mounting locations

The identified substitute parts meet the primary electrical criteria (2V operation, red color, diffused lens, ROHS3 compliance) but exhibit variations in secondary parameters that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

SSL-LX4064HD (Lumex Opto/Components Inc.):

This part shares identical electrical specifications with the WP813ID (2V forward voltage, 20mA test current, red diffused lens, through-hole mounting). Both components are ROHS3 compliant with unlimited MSL ratings and REACH unaffected status. The SSL-LX4064HD is mechanically incompatible due to its 4mm lens diameter versus the WP813ID's 10mm diameter; this part cannot be substituted in applications requiring 10mm panel cutout compatibility. The SSL-LX4064HD is suitable only for applications with 4mm mechanical mounting envelopes.

SSI-LXR1612ID (Lumex Opto/Components Inc.):

This part meets the electrical voltage requirement (2V) and shares red diffused lens characteristics with the WP813ID. However, it is mechanically incompatible for the following reasons: (1) 3mm lens diameter versus 10mm required diameter; (2) panel mount configuration versus through-hole mounting type; (3) flat-top lens style versus domed-top style. The SSI-LXR1612ID is not suitable as a direct substitute for WP813ID applications.

Compliance and Regulatory Status:

All identified parts maintain ROHS3 compliance, unlimited MSL rating (1), and REACH unaffected status, matching the WP813ID regulatory profile. No compliance barriers exist for substitution from a regulatory standpoint.

Mechanical Compatibility Determination:

Direct substitution of WP813ID is limited by the critical 10mm lens diameter specification. Parts with alternative lens sizes (3mm, 4mm) are mechanically incompatible with existing panel cutouts and mounting fixtures designed for 10mm components. Substitution is only viable when the mechanical mounting envelope can accommodate alternative lens diameters.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX4064HD replace WP813ID in my circuit?

A: SSL-LX4064HD matches the electrical specifications (2V, 20mA, red diffused) but is mechanically incompatible. The 4mm lens diameter cannot fit 10mm panel cutouts or mounting holes designed for WP813ID. Substitution is not possible without mechanical redesign of the mounting interface.

Q: What is the primary difference between WP813ID and SSI-LXR1612ID?

A: SSI-LXR1612ID is a panel-mount component with 3mm lens diameter and flat-top lens style, whereas WP813ID is a through-hole component with 10mm lens diameter and domed-top lens style. These are fundamentally different mechanical designs unsuitable for direct substitution.

Q: Are all three parts ROHS3 compliant?

A: Yes. WP813ID, SSL-LX4064HD, and SSI-LXR1612ID are all ROHS3 compliant with unlimited MSL ratings and REACH unaffected status. Regulatory compliance is equivalent across all three parts.

Q: What does "diffused lens" mean for these LEDs?

A: Diffused lens refers to the lens transparency characteristic. All three parts feature diffused lenses that scatter light over a wider viewing angle compared to clear lenses, reducing brightness concentration and improving visibility from off-axis viewing positions.

Q: Can I use SSI-LXR1612ID if I modify my PCB layout?

A: SSI-LXR1612ID is designed for panel-mount applications with 6.10mm (0.24") round cutout requirements, fundamentally different from through-hole mounting. Substitution would require complete redesign of the mounting interface and is not recommended as a direct replacement strategy.

Q: What is the significance of the 30° versus 60° viewing angle difference?

A: WP813ID has a 30° viewing angle (narrower cone), while SSL-LX4064HD and SSI-LXR1612ID have 60° viewing angles (wider cone). The 30° angle provides more concentrated brightness in a specific direction; the 60° angle distributes light over a broader area. Application requirements determine which viewing angle is appropriate.

Q: Why is the millicandela rating different between these parts?

A: Millicandela (mcd) rating indicates luminous intensity. WP813ID delivers 80mcd, SSL-LX4064HD delivers 5mcd, and SSI-LXR1612ID delivers 30mcd. Higher mcd values produce brighter indication. Application brightness requirements determine acceptable mcd ranges.

Q: Are there any current differences I should consider?

A: WP813ID and SSL-LX4064HD both operate at 20mA test current. SSI-LXR1612ID operates at 30mA maximum current. If your circuit is designed for 20mA operation, SSI-LXR1612ID would require current limiting resistor recalculation.
