Parameter Comparison

Engineering Selection Recommendations

EAST2012RA2 (Everlight Electronics Co Ltd): This substitute maintains identical package dimensions and mounting specifications. Forward voltage increases by 0.05V (2.05V vs 2V), within typical circuit tolerance margins. Luminous intensity increases to 63mcd, providing slightly enhanced brightness. Wavelength shift to 631.5nm remains within acceptable red spectrum range. Product status is Active with ROHS3 compliance and MSL 3 rating. Inventory availability is high (8442 pcs).

SML-LX0805SIC-TR (Lumex Opto/Components Inc.): This substitute provides identical electrical characteristics (2V forward voltage, 60mcd, 140° viewing angle) and package footprint. Height specification increases to 1.20mm (0.10mm above main part maximum), acceptable for standard PCB assembly processes. Peak wavelength at 636nm aligns with red spectrum requirements. Product status is Active with ROHS3 compliance and MSL 3 rating. Inventory availability is high (5009 pcs).

Both substitutes are qualified for direct replacement based on active product status, regulatory compliance certifications, and parametric compatibility within engineering tolerances.

Frequently Asked Questions (FAQ)

Q: Can EAST2012RA2 be used as a direct replacement for EAST2012RA3? A: Yes. Both parts share identical package dimensions (0805), mounting type (Surface Mount), color (Red), lens specifications, and test current (20mA). Forward voltage difference of 0.05V and luminous intensity increase of 3mcd are within acceptable operating tolerances for indication applications.

Q: What is the height difference between SML-LX0805SIC-TR and EAST2012RA3? A: SML-LX0805SIC-TR has a maximum height of 1.20mm compared to EAST2012RA3 at 1.10mm, a difference of 0.10mm. This variation is acceptable for standard surface mount PCB assembly and does not affect electrical performance.

Q: Are all substitute parts RoHS compliant? A: Yes. EAST2012RA2 and SML-LX0805SIC-TR both carry ROHS3 compliance certification, meeting regulatory requirements for electronic component manufacturing.

Q: What is the moisture sensitivity level for substitute parts? A: Both EAST2012RA2 and SML-LX0805SIC-TR are rated MSL 3 (168 Hours), indicating standard moisture handling requirements for surface mount components.

Q: Can wavelength differences affect circuit performance? A: Wavelength variations (EAST2012RA3 at 624nm dominant, EAST2012RA2 at 631.5nm, SML-LX0805SIC-TR at 636nm peak) remain within the red spectrum and do not affect electrical circuit operation. Visual color perception differences are minimal for indication applications.

Q: Which substitute offers better inventory availability? A: EAST2012RA2 provides higher inventory (8442 pcs) compared to SML-LX0805SIC-TR (5009 pcs), both significantly exceeding the main part stock level (819 pcs).
