WP7104PBC/Z Equivalent & Substitute Parts

Part Overview

The WP7104PBC/Z is a blue 465nm LED indication component manufactured by Kingbright, designed for through-hole mounting applications. This discrete radial LED operates at a typical forward voltage of 3.2V with a test current of 20mA and delivers 3000mcd luminous intensity. The component features a 3mm T-1 clear lens with a 20° viewing angle and is housed in a radial package configuration.

The WP7104PBC/Z carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this LED specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WP7104PBC/Z is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color specification: Blue
• Wavelength - Dominant: 465nm
• Lens size and type: 3mm T-1 clear lens
• Mounting configuration: Through-hole radial package
• Physical dimensions: 2.90mm diameter, 5.90mm maximum height
• Viewing angle: 20°

Allowable Variation Parameters:

• Forward voltage (Vf): Tolerance within typical operating range
• Millicandela rating: Variation acceptable within application brightness requirements
• Wavelength - Peak: Minor variation acceptable within blue spectrum
• Product status: Active status preferred for new designs; obsolete status acceptable for legacy support

The WP710A10QBC/G qualifies as a substitute based on matching primary compatibility criteria while operating within allowable variation parameters for forward voltage and luminous intensity.

Engineering Selection Recommendations

WP710A10QBC/G Substitution Assessment:

The WP710A10QBC/G is a direct substitute for the WP7104PBC/Z based on the following engineering factors:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. Both components carry identical ECCN and HTSUS classifications, supporting consistent export and import documentation.

Product Status Consideration: The WP710A10QBC/G carries active product status, providing supply chain continuity and long-term availability compared to the obsolete WP7104PBC/Z. This status transition supports ongoing production and future design iterations.

Electrical and Optical Compatibility: The forward voltage differential of 0.1V (3.2V to 3.3V) falls within acceptable operating tolerances for standard LED indication circuits. The luminous intensity reduction from 3000mcd to 2800mcd represents a 6.7% decrease, acceptable for indication applications where absolute brightness is not a critical design parameter. Both components operate at identical test current (20mA) and maintain matching viewing angle (20°) and dominant wavelength (465nm) specifications.

Physical and Mechanical Compatibility: Identical package dimensions (2.90mm diameter, 5.90mm maximum height), lens configuration (3mm T-1 clear domed), and mounting type (through-hole radial) ensure direct mechanical interchangeability without circuit board redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can the WP710A10QBC/G replace the WP7104PBC/Z in existing designs?

A: Yes. The WP710A10QBC/G is mechanically and electrically compatible with the WP7104PBC/Z. Both components share identical physical dimensions, package configuration, and mounting type. The 0.1V forward voltage increase and 200mcd luminous intensity reduction are within acceptable tolerances for standard LED indication applications.

Q: What is the significance of the forward voltage difference between these components?

A: The WP7104PBC/Z operates at 3.2V typical forward voltage, while the WP710A10QBC/G operates at 3.3V. This 0.1V difference requires circuit current-limiting resistor adjustment to maintain the 20mA test current specification. Standard LED indication circuits accommodate this voltage range without functional degradation.

Q: Are there mechanical compatibility concerns with substitution?

A: No. Both components feature identical 3mm T-1 lens packages with clear domed tops, 2.90mm diameter bodies, and 5.90mm maximum heights. Through-hole radial mounting configurations are identical, enabling direct board-level substitution without mechanical modification.

Q: How does the luminous intensity difference affect application performance?

A: The WP710A10QBC/G delivers 2800mcd compared to the WP7104PBC/Z at 3000mcd, representing a 6.7% reduction. For indication applications, this difference is typically imperceptible to human observation and does not compromise functional performance in standard signaling and status indication circuits.

Q: What is the wavelength compatibility between these components?

A: Both components specify 465nm dominant wavelength, ensuring color consistency in blue LED indication applications. Peak wavelength values differ slightly (458nm versus 461nm), but this variation remains within the blue spectrum and does not affect visual color perception or optical filtering compatibility.

Q: Why is the WP710A10QBC/G preferred over the obsolete WP7104PBC/Z?

A: The WP710A10QBC/G carries active product status, ensuring long-term supply availability and manufacturing continuity. The WP7104PBC/Z is obsolete, presenting supply chain risk and potential discontinuation. For new designs and ongoing production, the active-status substitute is the preferred selection.

Q: Are regulatory and compliance certifications maintained with substitution?

A: Yes. Both components maintain ROHS3 compliance, REACH unaffected status, and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Substitution does not introduce regulatory or compliance complications.
