Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 104090000 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Configuration: Common Cathode (electrical compatibility with existing circuit designs)
• Color: Red, Green, Blue (RGB) discrete emission
• Lens Transparency: Clear (optical performance matching)
• Mounting Type: Through Hole (mechanical fit in PCB)
• Current - Test: 20mA per color channel (driver circuit compatibility)
• Viewing Angle: 50° (optical field requirements)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance)
• ECCN and HTSUS classifications (regulatory compliance)

The substitute part WP154A4SUREQBFZGC from Kingbright satisfies all primary substitution criteria. While the package designation differs (T-1 3/4 versus 8mm Round), both are radial through-hole configurations with compatible mechanical and electrical properties. Forward voltage specifications remain within acceptable operational ranges for standard LED driver circuits.

Parameter Comparison

Engineering Selection Recommendations

The WP154A4SUREQBFZGC from Kingbright is a direct functional substitute for the obsolete 104090000. Selection is supported by the following engineering factors:

Product Status Alignment: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity.

Electrical Compatibility: Forward voltage specifications for the substitute (1.9V Red, 3.3V Green, 3.3V Blue) remain within acceptable tolerance ranges for standard LED driver circuits designed for the original part (2.1V Red, 3.15V Green, 3.15V Blue). Test current specifications are identical at 20mA per color channel.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The substitute part carries ROHS3 compliance certification, meeting current environmental standards.

Optical Performance: Millicandela ratings for the substitute exceed the original part across all color channels (400mcd vs. 350mcd Red; 1700mcd vs. 1150mcd Green; 900mcd vs. 600mcd Blue), providing enhanced brightness characteristics. Viewing angle remains constant at 50°.

Mechanical Considerations: Package transition from 8mm Round to T-1 3/4 represents a standard industry substitution. Both are radial through-hole configurations with compatible PCB mounting footprints. The substitute part exhibits reduced maximum height (8.60mm vs. 11.50mm), providing improved clearance in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the WP154A4SUREQBFZGC directly replace the 104090000 in existing circuit designs?

A: Yes. Both parts share identical configuration (common cathode), test current (20mA per channel), viewing angle (50°), and moisture sensitivity rating (MSL 1). Forward voltage differences are within acceptable operational ranges for standard LED driver circuits. No circuit redesign is required.

Q: What is the primary difference between the 8mm Round and T-1 3/4 package designations?

A: Both designations refer to radial through-hole LED packages with compatible mechanical mounting. The 8mm Round designation specifies an 8mm diameter lens, while T-1 3/4 indicates a 5mm diameter lens with domed top. Both mount identically in standard through-hole PCB footprints. The T-1 3/4 package provides reduced height (8.60mm vs. 11.50mm).

Q: Are there any compliance or certification differences between the two parts?

A: The substitute part (WP154A4SUREQBFZGC) carries ROHS3 compliance certification, while the original part does not specify RoHS status. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The substitute part is REACH Unaffected.

Q: How do the brightness specifications compare?

A: The WP154A4SUREQBFZGC provides higher millicandela ratings across all color channels: 400mcd Red (vs. 350mcd), 1700mcd Green (vs. 1150mcd), and 900mcd Blue (vs. 600mcd). This represents approximately 14% increase in red brightness, 48% increase in green brightness, and 50% increase in blue brightness.

Q: What is the wavelength difference between the two parts?

A: Peak wavelengths differ slightly: Red 645nm (vs. 625nm), Green 515nm (vs. 518nm), and Blue 460nm (vs. 466nm). These differences fall within standard LED color tolerance ranges and do not affect functional compatibility in RGB indication applications.

Q: Is the substitute part actively manufactured?

A: Yes. The WP154A4SUREQBFZGC maintains active product status with Kingbright, ensuring ongoing availability and supply chain reliability. The original 104090000 is classified as obsolete.
