WP7104CGCK Equivalent & Substitute Parts

Part Overview

The WP7104CGCK is a green LED indicator manufactured by Kingbright, designed for through-hole applications in discrete indication circuits. This component features a 3mm T-1 package with a clear domed lens, emitting at 570nm dominant wavelength with 350mcd luminous intensity at 20mA test current.

The WP7104CGCK is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this LED type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WP7104CGCK is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color: Green
• Wavelength - Dominant: 570nm
• Wavelength - Peak: 574nm
• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Lens Transparency: Clear
• Voltage - Forward (Vf) (Typ): 2.1V
• Current - Test: 20mA
• Viewing Angle: 34°
• Mounting Type: Through Hole
• Package / Case: Radial
• Size / Dimension: 2.90mm Dia
• Height (Max): 5.90mm
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Millicandela Rating: 330mcd to 350mcd (within acceptable luminous intensity range for indication applications)
• Product Status: Active substitutes preferred over obsolete
• Packaging: Bulk or standard packaging acceptable

The WP710A10CGCK meets all mandatory parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The WP710A10CGCK is the qualified substitute for the obsolete WP7104CGCK based on the following engineering criteria:

Product Status Advantage: The WP710A10CGCK carries Active product status, ensuring continued availability and manufacturing support from Kingbright. The WP7104CGCK is classified as Obsolete, making long-term sourcing unreliable.

Compliance Alignment: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for new designs and production environments.

Electrical and Optical Equivalence: Forward voltage (2.1V), test current (20mA), dominant wavelength (570nm), viewing angle (34°), and all optical characteristics are identical between the two parts.

Mechanical Compatibility: Both components share identical physical dimensions (2.90mm diameter, 5.90mm maximum height), lens configuration (3mm T-1 round domed clear), and radial through-hole mounting type. Direct board-level substitution is supported without PCB redesign.

Luminous Intensity Variance: The WP710A10CGCK operates at 330mcd compared to the WP7104CGCK at 350mcd. This 20mcd reduction (5.7% variance) remains within acceptable tolerance for indication applications where absolute brightness uniformity is not critical. Circuit designs using current-limiting resistors will accommodate this minor intensity difference without functional impact.

Frequently Asked Questions (FAQ)

Q: Can the WP710A10CGCK replace the WP7104CGCK in existing circuit designs?

A: Yes. The WP710A10CGCK is electrically and mechanically equivalent. Both parts operate at 2.1V forward voltage and 20mA test current, share identical 570nm dominant wavelength, and use the same 3mm T-1 through-hole radial package. No circuit modifications are required.

Q: What is the significance of the 20mcd difference in luminous intensity?

A: The WP710A10CGCK produces 330mcd versus 350mcd for the WP7104CGCK. For indication applications, this 5.7% reduction is within acceptable tolerance. If absolute brightness matching is required, adjust the current-limiting resistor value to increase forward current slightly, or verify the application does not depend on specific brightness thresholds.

Q: Are there packaging differences between these parts?

A: The WP7104CGCK is listed with standard packaging, while the WP710A10CGCK is supplied in Bulk packaging. Both use identical component specifications and radial through-hole configuration. Bulk packaging affects order quantities and tape-and-reel availability, not component performance or compatibility.

Q: Do both parts meet current regulatory standards?

A: Yes. Both the WP7104CGCK and WP710A10CGCK are ROHS3 Compliant and REACH Unaffected. They satisfy environmental and hazardous substance restrictions for current manufacturing and export requirements.

Q: Why is the WP7104CGCK classified as Obsolete?

A: Kingbright has discontinued the WP7104CGCK in favor of the WP710A10CGCK, which is the current Active production part. The WP710A10CGCK provides equivalent performance with assured long-term availability and manufacturing support.

Q: Can I use the WP710A10CGCK in high-volume production?

A: Yes. The WP710A10CGCK is an Active product with confirmed inventory (1900 Pcs New Original In Stock). Active status ensures consistent supply chain support and manufacturing continuity for production runs.
