Engineering Selection Recommendations

AM2520EC03 (Primary Selection): The AM2520EC03 remains the primary component choice when the specified 50mcd brightness and 2.0V forward voltage are required. This part is Active status with full ROHS3 compliance and MSL 3 rating. Current inventory of 2200 units supports immediate procurement.

SSL-LXA228SRC-TR11 (Substitute Selection): The SSL-LXA228SRC-TR11 is a qualified substitute when higher brightness output (600mcd) and lower forward voltage (1.7V) are acceptable within circuit design parameters. This part maintains identical mechanical compatibility, package configuration, and regulatory compliance. The wider 25° viewing angle and extended peak wavelength (660nm) represent operational differences within the red LED spectrum. MSL 4 rating (72 Hours) requires appropriate moisture control during storage and handling. Inventory availability of 12014 units supports sustained supply.

Both parts maintain Active product status and full compliance with ROHS3 and REACH requirements, supporting long-term design reliability.

Frequently Asked Questions (FAQ)

Q: Can SSL-LXA228SRC-TR11 be used as a direct replacement for AM2520EC03 in existing designs?

A: The SSL-LXA228SRC-TR11 is mechanically and electrically compatible within the 2-SMD, Gull Wing LED category. Circuit design must accommodate the lower forward voltage (1.7V vs 2.0V) and higher brightness output (600mcd vs 50mcd). Resistor values in current-limiting circuits may require adjustment to maintain proper LED operating current at 20mA.

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

A: The primary differences are forward voltage (2.0V vs 1.7V), brightness rating (50mcd vs 600mcd), viewing angle (20° vs 25°), and peak wavelength (627nm vs 660nm). Both operate at identical test current (20mA) and share identical mechanical dimensions and package configuration.

Q: Are there packaging format differences?

A: The AM2520EC03 is supplied in Tape & Reel (TR) format. The SSL-LXA228SRC-TR11 is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard surface mount assembly equipment.

Q: What is the impact of different MSL ratings?

A: The AM2520EC03 has MSL 3 (168 Hours) while SSL-LXA228SRC-TR11 has MSL 4 (72 Hours). MSL 4 requires more stringent moisture control during storage and handling. Components must be stored in dry conditions and baked according to IPC standards before reflow soldering if moisture absorption limits are exceeded.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory standards for hazardous substance restrictions and environmental compliance.

Q: Which part should be selected for new designs?

A: Selection depends on circuit requirements. Choose AM2520EC03 when 50mcd brightness and 2.0V forward voltage are specified. Choose SSL-LXA228SRC-TR11 when higher brightness (600mcd) and lower forward voltage (1.7V) provide design advantages. Both parts support equivalent long-term reliability and supply continuity.
