Key Parameters

Substitute Part Grouping Explanation

Substitute components are identified based on the following criteria derived from the main part specifications:

Critical Parameters for Substitution:

• Color temperature: 4000K (neutral white)
• Package type: 1411 (3528 Metric)
• Mounting type: Surface mount
• Viewing angle: 120°
• Physical dimensions: 0.138" L x 0.110" W (3.50mm x 2.80mm)
• RoHS3 compliance requirement

Allowable Variation Parameters:

• Forward voltage (Vf): Range permissible based on circuit design tolerance
• Test current (I-test): Variation acceptable if electrical characteristics maintain design intent
• Luminous flux: Dependent on application requirements
• Efficiency (lm/W): Higher efficiency acceptable without design alteration
• CRI: Values of 80 and above acceptable for neutral white 4000K applications
• Product status: Active components with established supply chain preferred for obsolete part replacement

The identified substitute parts maintain identical package geometry, color temperature specification, and mounting characteristics while offering improved or equivalent electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

EAHC2835WD3 (Everlight Electronics Co Ltd): This substitute part is actively manufactured and stocked. It maintains the 1411 (3528 Metric) package geometry and 4000K neutral white color temperature specification. The forward voltage of 3.1V is within acceptable tolerance of the original 3.2V specification. RoHS3 compliance and MSL 3 (168 hours) moisture sensitivity provide improved handling characteristics. CRI value of 90 exceeds the original specification of 80, supporting applications requiring higher color rendering fidelity.

EAHE2835WD33 (Everlight Electronics Co Ltd): This substitute part is actively manufactured and available. The 1411 (3528 Metric) package maintains physical compatibility with design requirements. Forward voltage of 2.85V differs from the original 3.2V specification and requires circuit evaluation for applications with strict voltage compliance requirements. Test current of 65mA closely aligns with the original 60mA specification. RoHS3 compliance and MSL 3 (168 hours) moisture sensitivity meet manufacturing standards. Lumens per watt efficiency of 184 lm/W represents the highest efficiency among the three parts.

Both substitute parts are ROHS3 compliant and offer improved or equivalent performance characteristics while maintaining package compatibility and color temperature specification.

Frequently Asked Questions (FAQ)

Q: Can EAHC2835WD3 and EAHE2835WD33 be used interchangeably with SM2835UWDN02?

A: Both parts maintain identical package geometry (1411/3528 Metric), color temperature (4000K neutral white), mounting type (surface mount), and viewing angle (120°). However, electrical characteristics differ: EAHC2835WD3 operates at 3.1V / 150mA test current, while EAHE2835WD33 operates at 2.85V / 65mA test current compared to the original 3.2V / 60mA. Circuit-level design evaluation is necessary to confirm compatibility with your specific electrical requirements.

Q: What is the key difference in current requirements between these parts?

A: The SM2835UWDN02 original part operates at 60mA test current. EAHC2835WD3 requires significantly higher current at 150mA (2.5× increase), while EAHE2835WD33 operates at 65mA (comparable to original). Current selection depends on circuit design and thermal management capabilities. Higher current operation may require circuit redesign.

Q: How do forward voltage differences affect substitution?

A: SM2835UWDN02 specifies 3.2V typical forward voltage. EAHC2835WD3 operates at 3.1V (0.1V lower) and EAHE2835WD33 operates at 2.85V (0.35V lower). These variations require evaluation within your circuit design constraints. Applications with tight voltage compliance margins or series-connected LED chains require confirmation that the different forward voltages do not compromise performance.

Q: Are the physical dimensions compatible?

A: All three parts share identical package designations (1411/3528 Metric) and external dimensions: 0.138" L x 0.110" W (3.50mm x 2.80mm). Maximum seated heights show minor variation: SM2835UWDN02 at 0.030" (0.75mm) versus EAHC2835WD3 and EAHE2835WD33 at 0.033" (0.85mm). This 0.003" (0.10mm) height difference is within typical PCB reflow assembly tolerances.

Q: What is the significance of CRI differences?

A: SM2835UWDN02 specifies CRI 80, indicating acceptable color rendering for general lighting applications. EAHC2835WD3 specifies CRI 90 (higher), supporting applications requiring enhanced color rendering accuracy. EAHE2835WD33 maintains CRI 80 specification. CRI selection depends on application visual requirements.

Q: How do moisture sensitivity levels (MSL) differ?

A: SM2835UWDN02 specifies MSL 4 (72-hour floor life), while both substitutes specify MSL 3 (168-hour floor life). Lower MSL values indicate better moisture resistance. The substitute parts provide extended storage and handling windows without requiring special moisture control measures, representing an operational improvement.

Q: Which substitute part offers the highest efficiency?

A: EAHE2835WD33 provides 184 lm/W efficiency, compared to SM2835UWDN02 at 120 lm/W and EAHC2835WD3 at 133 lm/W. Higher efficiency reduces thermal load and power consumption, but this characteristic must be evaluated against the other electrical parameter variations (particularly the lower 2.85V forward voltage).
