EAPL2835WB3 Equivalent & Substitute Parts

Part Overview

The EAPL2835WB3 is a surface-mount LED lighting component manufactured by Everlight Electronics Co Ltd, classified as a cool white LED with a correlated color temperature (CCT) of 6500K. This part operates at 3.25V forward voltage with a nominal test current of 60mA and delivers 28 lumens at 25°C under test conditions. The component is housed in a 2-PLCC package with 1411 (3528 Metric) dimensions and features a 120° viewing angle.

The EAPL2835WB3 maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and thermal characteristics align with the original specification, allowing for direct circuit-level replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EAPL2835WB3 is determined by strict alignment of the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) must match at 3.25V typical
• Test current must match at 60mA nominal
• Maximum current rating must be 75mA or greater
• Flux output at 25°C test conditions must fall within the specified range (22–33 lumens)
• Lumens per watt efficiency must match at 144 lm/W

Mechanical Compatibility:

• Package type must be 2-PLCC
• Case designation must be 1411 (3528 Metric)
• Physical dimensions (L × W × H) must be identical: 3.50mm × 2.80mm × 0.85mm maximum seated height
• Viewing angle must be 120°

Thermal & Environmental:

• Thermal resistance must be 50°C/W
• CRI must be 80 or higher
• RoHS3 compliance required
• MSL rating must be 3 (168 Hours) or better

Color Temperature Tolerance: While the EAPL2835WB3 specifies 6500K (cool white), substitute parts may operate at adjacent color temperatures within the cool white spectrum (5000K–6500K range) provided all other electrical, mechanical, and thermal parameters remain identical. This allowance reflects industry-standard color temperature binning practices for white LEDs.

The EAPL2835WA7 meets all substitution criteria with the exception of color temperature, which is specified at 5000K rather than 6500K.

Parameter Comparison

Engineering Selection Recommendations

EAPL2835WA7 as Direct Substitute:

The EAPL2835WA7 is electrically and mechanically equivalent to the EAPL2835WB3 across all critical parameters: forward voltage, test current, maximum current, flux output, efficiency, viewing angle, package type, physical dimensions, thermal resistance, CRI, and compliance certifications. Both parts are manufactured by Everlight Electronics Co Ltd and maintain Active product status with ROHS3 compliance and identical MSL ratings.

The sole parameter difference is correlated color temperature: EAPL2835WA7 operates at 5000K (neutral white) versus EAPL2835WB3 at 6500K (cool white). This difference reflects color temperature binning within the white LED spectrum and does not affect electrical circuit operation, thermal performance, or mechanical fit.

Selection Criteria:

• Use EAPL2835WB3 when 6500K cool white color temperature is specified in the application design or when exact CCT matching to the original part is required.
• Use EAPL2835WA7 when 5000K neutral white color temperature is acceptable, when EAPL2835WB3 inventory is unavailable, or when the application permits color temperature variation within the cool-to-neutral white range.

Both parts are suitable for direct PCB-level substitution without circuit redesign, provided the application tolerates the color temperature difference.

Frequently Asked Questions (FAQ)

Q: Can EAPL2835WA7 replace EAPL2835WB3 in my circuit?

A: Yes. The EAPL2835WA7 is electrically and mechanically equivalent. Both parts share identical forward voltage (3.25V), test current (60mA), maximum current (75mA), flux output (28 lumens at 25°C), efficiency (144 lm/W), viewing angle (120°), package type (2-PLCC), physical dimensions (3.50mm × 2.80mm × 0.85mm), thermal resistance (50°C/W), and compliance certifications. The only difference is color temperature: EAPL2835WA7 is 5000K (neutral white) while EAPL2835WB3 is 6500K (cool white). Direct substitution is possible if the application tolerates this color temperature difference.

Q: What is the difference between 6500K and 5000K color temperature?

A: Both are within the white LED spectrum. 6500K (EAPL2835WB3) produces a cooler, more bluish-white appearance similar to daylight. 5000K (EAPL2835WA7) produces a neutral white appearance. The difference is perceptual only; electrical performance and circuit operation are identical.

Q: Are the packages identical?

A: Yes. Both EAPL2835WB3 and EAPL2835WA7 use the 2-PLCC package with 1411 (3528 Metric) case designation. Physical dimensions are 3.50mm length × 2.80mm width × 0.85mm maximum seated height. Both are surface-mount components suitable for identical PCB layouts.

Q: Do both parts have the same thermal characteristics?

A: Yes. Both parts have thermal resistance of 50°C/W and identical MSL rating of 3 (168 Hours). Thermal management and moisture handling requirements are equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both EAPL2835WB3 and EAPL2835WA7 are ROHS3 compliant and maintain Active product status.

Q: Can I mix EAPL2835WB3 and EAPL2835WA7 in the same application?

A: Mixing is possible if the application design permits color temperature variation. If uniform color temperature across all LEDs is required, use only one part number. If color temperature variation is acceptable, both parts can be used together without electrical or mechanical issues.

Q: What is the CRI of both parts?

A: Both parts have a Color Rendering Index (CRI) of 80, indicating equivalent color rendering capability.
