Key Parameters

Substitute Part Grouping Explanation

Substitution of the EAPL2835GA1 is determined by the following critical parameters:

Color Match: Green wavelength emission is mandatory for optical compatibility.

Electrical Compatibility: Forward voltage (Vf) and maximum current ratings must accommodate existing circuit designs without requiring significant modifications to current-limiting resistor networks or power supply specifications.

Luminous Output: Luminous flux and efficiency (lm/W) determine functional brightness performance; substitutes must deliver comparable light output at equivalent or lower operating currents.

Mechanical Fit: Surface mount package type and overall dimensions (length, width, height) must be compatible with PCB footprints and assembly equipment specifications.

Thermal Characteristics: Thermal resistance affects heat dissipation performance in the application environment.

Compliance & Availability: Product status (active vs. obsolete) and moisture sensitivity classification impact supply chain reliability and handling requirements.

The substitute part L135-G525003500000 (Lumileds LUXEON 3535L) meets these substitution criteria through equivalent color specification, compatible electrical parameters, superior luminous output capability, and active product status with improved moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EAPL2835GA1 is classified as obsolete, creating supply chain risk for new production and long-term availability. The L135-G525003500000 maintains active product status with established supply channels.

Compliance & Regulatory: The L135-G525003500000 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement in regulated markets.

Electrical Compatibility: Forward voltage differential (3.15 V vs. 3.2 V) is 0.05 V, representing a 1.6% variance within typical circuit tolerance margins. Existing current-limiting resistor designs require verification but generally accommodate this variance without modification.

Moisture Sensitivity: The substitute part features MSL 2 (1 Year) compared to MSL 3 (168 Hours), providing extended shelf life and reduced handling constraints during storage and assembly operations.

Thermal Performance: Improved thermal resistance (42°C/W vs. 50°C/W) enhances heat dissipation capability, supporting higher operating currents or extended duty cycles without exceeding junction temperature limits.

Package Footprint: The 1414 (3535 Metric) package is 0.6 mm wider than the 1411 (3528 Metric) package. PCB layout verification is required to confirm footprint compatibility with existing designs. Height differential (0.90 mm vs. 0.85 mm) is 0.05 mm and does not present clearance concerns for standard assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the L135-G525003500000 be used as a direct replacement for the EAPL2835GA1 without circuit modifications?

A: Electrical substitution is feasible with circuit verification. The forward voltage difference (3.15 V to 3.2 V) is minimal and typically accommodated by existing current-limiting resistor networks. However, PCB footprint compatibility must be confirmed due to package size differences (3528 vs. 3535 Metric). Consult PCB layout documentation and assembly equipment specifications before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Package size: 1411 (3528) vs. 1414 (3535), with the substitute 0.6 mm wider; (2) Luminous output: 4 lm vs. 22 lm at respective test currents; (3) Test current: 20 mA vs. 100 mA; (4) Product status: Obsolete vs. Active; (5) Moisture sensitivity: MSL 3 vs. MSL 2; (6) Regulatory compliance: ROHS3 and REACH certifications on the substitute.

Q: Is the higher luminous flux of the L135-G525003500000 a concern for my application?

A: Higher luminous flux is not inherently problematic. If brightness reduction is required, circuit design can limit operating current below the 100 mA test specification. Verify that the application's optical and thermal requirements are met at the intended operating point.

Q: What is the impact of the different package sizes on PCB assembly?

A: The 1414 (3535 Metric) package is larger than the 1411 (3528 Metric) package. Existing PCB footprints designed for the 3528 package may not accommodate the 3535 package without layout modification. Verify footprint compatibility with your PCB design files and confirm that assembly equipment can handle the substitute package format.

Q: Does the improved thermal resistance of the substitute part affect circuit design?

A: The lower thermal resistance (42°C/W vs. 50°C/W) of the substitute part improves heat dissipation. This allows higher operating currents or extended duty cycles without exceeding junction temperature limits. No circuit modifications are required; this represents an improvement in thermal performance.

Q: Are there any supply chain advantages to using the L135-G525003500000?

A: Yes. The L135-G525003500000 is an active product with established supply availability, whereas the EAPL2835GA1 is obsolete. Active product status ensures long-term procurement reliability and reduces risk of supply discontinuation.
