WP383IDT Equivalent & Substitute Parts

Part Overview

The WP383IDT is an active, through-hole mounted red LED indicator manufactured by Kingbright. This diffused rectangular LED operates at 2V forward voltage with a 3mcd brightness rating and 617nm dominant wavelength. The component is designed for discrete indication applications requiring a 2.5mm x 5.00mm lens format with 110° viewing angle. Substitute parts are identified to address inventory availability, lead time requirements, or specific mechanical constraints while maintaining electrical and optical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The WP513IDT is identified as a direct substitute for the WP383IDT based on the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 2V (identical)
• Test current: 20mA (identical)
• Wavelength - Dominant: 617nm (identical)
• Wavelength - Peak: 627nm (identical)
• Brightness rating: 3mcd (identical)

Optical Compatibility:

• Color: Red (identical)
• Lens transparency: Diffused (identical)
• Lens style: Rectangle with Flat Top (identical)
• Lens size: 5.00mm x 2.50mm (identical)
• Viewing angle: 110° (identical)

Mechanical Compatibility:

• Mounting type: Through Hole (identical)
• Package / Case: Radial (identical)
• Supplier device package: Rectangular 2.5mmx5mm (identical)

Regulatory Compliance:

• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)

The WP513IDT differs only in maximum height (8.50mm versus 9.60mm), which represents a mechanical variation that does not affect electrical or optical performance. This height difference may be advantageous in space-constrained applications.

Parameter Comparison

Engineering Selection Recommendations

Both the WP383IDT and WP513IDT are active products manufactured by Kingbright with identical electrical, optical, and regulatory compliance characteristics. Selection between these parts is determined by the following factors:

Mechanical Fit: The WP513IDT has a maximum height of 8.50mm compared to the WP383IDT at 9.60mm. Applications with vertical space constraints benefit from the WP513IDT. Applications without height restrictions accept either part.

Inventory and Lead Time: The WP513IDT has higher inventory availability (1881 Pcs) compared to the WP383IDT (753 Pcs). Selection based on supply chain requirements is valid.

Regulatory Compliance: Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical moisture sensitivity ratings. No compliance-based differentiation exists.

Functional Equivalence: The parts are functionally equivalent for all indication applications requiring 2V, 20mA red LED operation with 3mcd brightness and 617nm wavelength specification.

Frequently Asked Questions (FAQ)

Q: Can the WP513IDT replace the WP383IDT in existing circuit designs?

A: Yes. The WP513IDT is electrically and optically identical to the WP383IDT. Both operate at 2V forward voltage, 20mA test current, and produce identical 617nm dominant wavelength output. The only difference is mechanical height (8.50mm versus 9.60mm), which does not affect circuit function.

Q: What is the significance of the height difference between these parts?

A: The WP513IDT is 1.10mm shorter in maximum height. This difference is relevant only in applications with vertical space constraints or specific mechanical envelope requirements. For standard through-hole mounting applications without height restrictions, this difference is not significant.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both parts use identical radial through-hole mounting with the same lens dimensions (5.00mm x 2.50mm) and supplier device package (Rectangular 2.5mmx5mm). PCB footprints designed for either part accommodate both.

Q: Do these parts have identical optical characteristics?

A: Yes. Both parts have identical lens transparency (Diffused), lens style (Rectangle with Flat Top), viewing angle (110°), and brightness rating (3mcd). Optical performance is identical.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level ratings (1 - Unlimited). Regulatory status is identical.

Q: Which part should be selected for new designs?

A: Selection is based on availability and mechanical constraints. The WP513IDT offers higher inventory availability and reduced height. The WP383IDT is selected when the additional 1.10mm height is not a constraint and inventory is sufficient.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts are active products with identical electrical and optical specifications. Interchangeable use in production is supported by the parameter equivalence documented in this reference.
