Key Parameters

Substitute Part Grouping Explanation

Substitution of the EAST2012BA0 is determined by strict alignment of the following critical parameters:

Wavelength Compatibility: Both the dominant wavelength (471nm) and peak wavelength (468nm) must match to ensure color consistency in indication applications.

Lens Geometry: The lens style (Rectangle with Flat Top) and lens size (1.40mm x 1.25mm) must be identical to maintain optical performance and mechanical fit within existing PCB layouts.

Mounting Configuration: Surface mount technology with 0805 (2012 Metric) package designation and 2.00mm L x 1.25mm W footprint dimensions must be preserved for PCB compatibility.

Electrical Characteristics: Forward voltage (Vf) and test current (20mA) define the operating point. Variations in these parameters affect circuit design and may require redesign of current-limiting resistor networks.

Viewing Angle: The 140° specification must be maintained for consistent optical performance in the intended application context.

The EAST2012BA5 qualifies as a substitute based on matching wavelength, lens geometry, mounting type, and viewing angle specifications. Differences in forward voltage (3V vs 3.3V) and brightness rating (79mcd vs 50mcd) represent measurable variations that must be evaluated within specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EAST2012BA0 is classified as obsolete, making the EAST2012BA5 the appropriate active alternative from Everlight Electronics Co Ltd. The EAST2012BA5 maintains active product status with confirmed inventory availability (1165 Pcs New Original In Stock).

Compliance and Certifications: The EAST2012BA5 carries RoHS3 Compliant certification, indicating adherence to current environmental and material restriction standards. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence for export and trade purposes.

Electrical Parameter Variance: The forward voltage difference (3V vs 3.3V) represents a 0.3V reduction in the EAST2012BA5. This variance requires evaluation of the existing current-limiting resistor network in the application circuit. Designs with fixed resistor values may experience increased current flow and brightness output with the substitute part.

Brightness Increase: The EAST2012BA5 provides 79mcd compared to the original 50mcd specification, representing a 58% increase in luminous intensity. This enhanced brightness may be acceptable or beneficial depending on application visibility requirements, but should be confirmed against design specifications.

Mechanical Compatibility: The height difference (1.30mm vs 1.10mm) represents a 0.20mm increase. This variance must be verified against PCB clearance requirements and any mechanical constraints within the assembly environment.

Frequently Asked Questions (FAQ)

Q: Can the EAST2012BA5 be used as a direct replacement for the EAST2012BA0 without circuit modification?

A: The EAST2012BA5 shares identical wavelength, lens geometry, mounting type, and viewing angle specifications with the EAST2012BA0. However, the forward voltage difference (3V vs 3.3V) and increased brightness (79mcd vs 50mcd) may affect circuit performance. Existing current-limiting resistor values should be verified to ensure the application operates within acceptable brightness and current parameters.

Q: What is the significance of the height difference between these parts?

A: The EAST2012BA5 has a maximum height of 1.30mm compared to 1.10mm for the EAST2012BA0, representing a 0.20mm increase. This difference must be evaluated against PCB layout clearance requirements, particularly in applications with height-constrained assembly environments or where components are positioned near other circuit elements.

Q: Are the wavelength specifications identical between the main part and substitute?

A: Yes. Both the EAST2012BA0 and EAST2012BA5 specify identical dominant wavelength (471nm) and peak wavelength (468nm), ensuring color consistency and optical performance equivalence in indication applications.

Q: What compliance certifications apply to the EAST2012BA5?

A: The EAST2012BA5 is RoHS3 Compliant and shares identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications with the EAST2012BA0. Both parts maintain MSL 2 (1 Year) moisture sensitivity level ratings.

Q: How does the increased brightness of the EAST2012BA5 affect application suitability?

A: The EAST2012BA5 provides 79mcd versus the original 50mcd, representing a 58% brightness increase. This enhanced luminous intensity may improve visibility in certain applications but should be confirmed against design specifications to ensure the application does not require the original brightness level.

Q: Are the package and footprint dimensions identical?

A: The footprint dimensions are identical: 2.00mm L x 1.25mm W for both parts. Both use 0805 (2012 Metric) surface mount packages. The lens size (1.40mm x 1.25mm) and lens style (Rectangle with Flat Top) are also identical, ensuring mechanical compatibility with existing PCB layouts.
