EAST2012YA0 Yellow LED 0805 SMD - Equivalent & Substitute Parts

Part Overview

The EAST2012YA0 is an active yellow LED indication component manufactured by Everlight Electronics Co Ltd, designed for surface mount applications in the 0805 (2012 Metric) package format. This discrete LED operates at 2.4V forward voltage with a 50mcd brightness rating and 590nm dominant wavelength, suitable for standard indicator applications requiring yellow light emission. The component is ROHS3 compliant and currently in active production status with 893 units available in inventory.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers while preserving the core functional requirements of yellow LED indication in the 0805 package.

Substitute Part Grouping Explanation

Substitution eligibility for the EAST2012YA0 is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Package / Case: 0805 (2012 Metric) - ensures PCB footprint compatibility
• Mounting Type: Surface Mount - maintains assembly process compatibility
• Color: Yellow - preserves optical output specification
• Wavelength - Peak: 590-591nm range - maintains spectral output within yellow LED specification
• Viewing Angle: 140° - ensures consistent light distribution
• Lens Transparency: Clear - maintains optical clarity
• RoHS Status: ROHS3 Compliant - satisfies regulatory requirements

Allowable Parameter Variations:

• Voltage - Forward (Vf): Substitute parts with Vf between 2.1V and 2.4V are acceptable, as this range permits circuit redesign through resistor value adjustment without altering fundamental circuit topology
• Millicandela Rating: Substitute parts with brightness ratings of 50mcd or higher maintain or exceed the original specification
• Height (Max): Variations within 0.10mm are acceptable for surface mount assembly compatibility

The SML-LX0805SYC-TR manufactured by Lumex Opto/Components Inc. meets all mandatory matching parameters and falls within allowable variations for electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (EAST2012YA0): The EAST2012YA0 remains the preferred selection when Everlight Electronics supply is available. The component is in active production status with established inventory levels (893 units) and meets all ROHS3 compliance requirements. The 2.4V forward voltage and 50mcd brightness rating are the specified baseline for circuit design.

Substitute Part Selection (SML-LX0805SYC-TR): The SML-LX0805SYC-TR is a valid substitute when EAST2012YA0 availability is constrained. This Lumex component maintains identical package, mounting type, color, viewing angle, and lens transparency specifications. The 0.3V reduction in forward voltage (2.1V vs 2.4V) requires circuit resistor recalculation to maintain 20mA test current, but does not alter circuit topology or functionality. The increased brightness rating (60mcd vs 50mcd) provides enhanced optical output. Both components maintain ROHS3 compliance and identical MSL ratings.

Compliance Verification: Both components satisfy ROHS3 compliance and EAR99 export classification requirements. Moisture sensitivity level 3 (168 hours) applies to both parts, requiring identical storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX0805SYC-TR be used as a direct drop-in replacement without circuit modification?

A: No. The SML-LX0805SYC-TR has a forward voltage of 2.1V compared to the EAST2012YA0 at 2.4V. This 0.3V difference requires recalculation of the current-limiting resistor value to maintain the specified 20mA test current. The resistor value adjustment is the only circuit modification required; no other design changes are necessary.

Q: Are the physical dimensions compatible for PCB assembly?

A: Yes. Both components use the 0805 (2012 Metric) package with identical length (2.00mm) and width (1.25mm) dimensions. The height difference (1.10mm vs 1.20mm) is within standard surface mount assembly tolerances and does not affect PCB footprint compatibility or reflow soldering processes.

Q: Do both parts have the same storage and handling requirements?

A: Yes. Both the EAST2012YA0 and SML-LX0805SYC-TR are classified as Moisture Sensitivity Level 3 (168 hours), requiring identical storage conditions and handling protocols. No additional precautions are necessary when switching between these components.

Q: What is the brightness difference between these two LEDs?

A: The SML-LX0805SYC-TR provides 60mcd brightness compared to the EAST2012YA0 at 50mcd. This 10mcd increase represents a 20% brightness enhancement. Both components maintain the same 140° viewing angle and clear lens transparency, so the increased brightness is distributed across the same optical pattern.

Q: Are both components RoHS compliant?

A: Yes. Both the EAST2012YA0 and SML-LX0805SYC-TR are ROHS3 compliant and carry EAR99 export classification. They meet identical regulatory requirements for hazardous substance restrictions.

Q: What is the wavelength difference between these LEDs?

A: The EAST2012YA0 has a peak wavelength of 591nm with a dominant wavelength of 590nm. The SML-LX0805SYC-TR has a peak wavelength of 590nm. Both wavelengths fall within the standard yellow LED specification range and produce visually equivalent yellow light output.
