WP63GT Green LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The WP63GT is an active green LED indicator manufactured by Kingbright, designed for through-hole mounting applications. This discrete LED operates at 2.2V forward voltage with a 568nm dominant wavelength and delivers 80 millicandela brightness at 20mA test current. The component features a 5mm clear domed lens with 30° viewing angle and is housed in a T-1 3/4 radial package.

Substitute parts are necessary when the WP63GT becomes unavailable, when alternative packaging formats are required, or when design specifications allow for variations in brightness, voltage characteristics, or viewing angle within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the WP63GT is based on the following allowed parameters:

Critical Matching Parameters:

• Color: Green
• Lens Transparency: Clear
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• Supplier Device Package: T-1 3/4

Operational Parameters (Acceptable Variation Range):

• Voltage - Forward (Vf): 2.1V to 2.2V
• Current - Test: 10mA to 20mA
• Millicandela Rating: 10.6mcd to 170mcd
• Wavelength - Dominant: 565nm to 572nm
• Viewing Angle: 25° to 40°

Compliance Parameters:

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

Substitute parts must satisfy all critical matching parameters. Operational parameters may vary within the specified ranges based on application requirements. All substitutes must maintain equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

HLMP-C523-J0002 (Broadcom Limited) and SSL-LX5093LGT (Lumex Opto/Components Inc.) are the preferred substitutes. Both maintain active product status and ROHS3 compliance. HLMP-C523-J0002 offers higher brightness at 170mcd with identical forward voltage (2.2V) and test current (20mA), suitable for applications requiring enhanced visibility. SSL-LX5093LGT matches the WP63GT brightness specification at 80mcd with identical electrical and optical characteristics.

SSL-LX5063LGT (Lumex Opto/Components Inc.) provides an alternative with matching brightness (40mcd) and identical forward voltage and test current, with equivalent height to the WP63GT at 6.00mm maximum.

Secondary Substitutes (Conditional Use):

HLMP-3568 (Broadcom Limited) operates at reduced test current (10mA) and lower brightness (10.6mcd), suitable only for applications where lower brightness is acceptable and power consumption reduction is beneficial. Forward voltage is 2.1V, requiring circuit verification.

SLR-56MC3F (Rohm Semiconductor) carries "Not For New Designs" status and operates at 2.1V forward voltage with 10mA test current. Use only in legacy system maintenance where original specifications are mandatory.

Not Recommended:

MV5452 (onsemi) carries obsolete product status and should not be selected for new designs or ongoing production applications.

Frequently Asked Questions (FAQ)

Q: Can HLMP-C523-J0002 replace WP63GT in all applications?

A: HLMP-C523-J0002 is mechanically and electrically compatible as a direct substitute. It operates at identical forward voltage (2.2V) and test current (20mA). The higher brightness rating (170mcd versus 80mcd) and narrower viewing angle (25° versus 30°) must be evaluated against specific application requirements. Both parts are ROHS3 compliant and maintain equivalent regulatory status.

Q: What is the difference between the Broadcom and Lumex substitutes?

A: HLMP-C523-J0002 (Broadcom) is supplied in Cut Tape packaging with maximum height of 8.91mm. SSL-LX5093LGT (Lumex) is supplied in Bulk packaging with maximum height of 8.60mm. Both match the WP63GT electrical specifications (2.2V, 20mA, 80mcd). HLMP-C523-J0002 offers higher inventory availability (28363 units). SSL-LX5093LGT provides closer dimensional match to the original WP63GT height (6.00mm versus 8.60mm).

Q: Why do some substitutes operate at 2.1V instead of 2.2V?

A: HLMP-3568 and SLR-56MC3F operate at 2.1V forward voltage, which is within the acceptable variation range for green LEDs. This 0.1V difference requires circuit verification to ensure proper current limiting and brightness performance. These parts are suitable only when circuit design accommodates the lower voltage specification.

Q: What does "Not For New Designs" mean for SLR-56MC3F?

A: This status indicates the manufacturer (Rohm Semiconductor) does not recommend this part for new product development. SLR-56MC3F should be used only for replacement or maintenance of existing systems where the original specification is mandatory. For new designs, select from parts with "Active" product status.

Q: Is MV5452 a viable substitute?

A: MV5452 carries obsolete product status and is not recommended for any new applications. While inventory is available (668 units), the obsolete classification indicates the manufacturer has discontinued support and may not guarantee future availability or consistency. Select from active status alternatives instead.

Q: How does viewing angle affect substitution?

A: The WP63GT has a 30° viewing angle. Substitutes range from 25° (HLMP-C523-J0002) to 40° (HLMP-3568, SLR-56MC3F). Narrower angles concentrate light intensity in a smaller cone; wider angles distribute light over a broader area. Application requirements determine acceptable variation. For direct replacement without optical redesign, SSL-LX5063LGT and SSL-LX5093LGT maintain the 30° specification.

Q: What packaging options are available?

A: WP63GT is supplied in Bulk packaging. HLMP-C523-J0002 is available in Cut Tape (CT) format, which may be preferred for automated assembly processes. All other substitutes are supplied in Bulk packaging. Packaging selection depends on manufacturing process requirements and order quantities.

Q: Are all substitutes RoHS3 compliant?

A: HLMP-C523-J0002, HLMP-3568, SLR-56MC3F, SSL-LX5063LGT, and SSL-LX5093LGT are all ROHS3 compliant. MV5452 compliance status is not specified in available documentation. For applications requiring verified RoHS3 compliance, select from the confirmed compliant alternatives.
