Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM2520YC09 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow (wavelength peak 590nm)
• Voltage - Forward (Vf): 2.1V nominal
• Current - Test: 20mA
• Package / Case: 2-SMD configuration
• Lens Size: 1.90mm Dia
• Mounting Type: Surface Mount
• Size / Dimension: 2.50mm L x 2.00mm W
• RoHS Status: ROHS3 Compliant

Acceptable Variation Parameters:

• Millicandela Rating: Substitutes may vary (50mcd baseline)
• Viewing Angle: Substitutes may vary (20° baseline)
• Height (Max): Substitutes within 2.83mm to 3.00mm acceptable
• MSL Rating: Substitutes with MSL 3 or MSL 4 acceptable
• Mounting Configuration: Z-Bend or Gull Wing both acceptable for surface mount applications

The substitute parts SSL-LXA228SYC-TR31 and SSL-LXA228SYC-TR11 meet the primary compatibility criteria. SSL-LXA228SOC-TR11 is listed as an alternative for applications where orange color is functionally equivalent.

Parameter Comparison

Engineering Selection Recommendations

SSL-LXA228SYC-TR31 (Primary Substitute)

This part provides the closest electrical and mechanical alignment with AM2520YC09. Both components feature identical forward voltage (2.1V), matching Z-Bend package configuration, and equivalent wavelength peak (590nm). Height differential of 0.07mm is within acceptable PCB assembly tolerances. ROHS3 compliance and identical dimensional footprint (2.50mm L x 2.00mm W) ensure direct substitution capability. MSL 4 rating requires controlled storage conditions (72 hours) compared to MSL 3, which may impact manufacturing logistics but does not affect functional performance.

SSL-LXA228SYC-TR11 (Secondary Substitute)

This yellow LED maintains color and wavelength compatibility (590nm peak) with identical test current (20mA) and lens specifications. Forward voltage is 2V versus 2.1V, representing a 0.1V differential within typical LED tolerance ranges. Gull Wing package configuration differs from Z-Bend but maintains surface mount compatibility. Height of 3.00mm exceeds original by 0.10mm; verify PCB clearance in space-constrained applications. ROHS3 compliance confirmed. Higher millicandela rating (300mcd) provides increased brightness margin.

SSL-LXA228SOC-TR11 (Color Alternative)

Orange wavelength (620nm peak) differs from yellow specification. This part is listed as substitute only for applications where color distinction is not functionally critical or where orange indication is acceptable. Forward voltage (2V) and test current (20mA) align with electrical requirements. Gull Wing configuration and 3.00mm height require PCB layout verification. Significantly higher brightness (700mcd) may necessitate current-limiting resistor adjustment.

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with original part.

Frequently Asked Questions (FAQ)

Q: Can SSL-LXA228SYC-TR31 directly replace AM2520YC09 without PCB modification?

A: Yes. Both parts share identical forward voltage (2.1V), wavelength peak (590nm), test current (20mA), and footprint dimensions (2.50mm L x 2.00mm W). Height difference of 0.07mm is within standard PCB assembly tolerances. Z-Bend package configuration is identical. No circuit modifications required.

Q: What is the impact of MSL 4 rating on SSL-LXA228SYC-TR31 versus MSL 3 on AM2520YC09?

A: MSL 4 requires moisture bake-out after 72 hours of exposure to ambient conditions, compared to 168 hours for MSL 3. This affects component storage and handling procedures but does not impact electrical performance or reliability after assembly. Manufacturing processes must accommodate shorter shelf-life windows.

Q: Why does SSL-LXA228SYC-TR11 have different forward voltage (2V vs 2.1V)?

A: The 0.1V differential falls within standard LED manufacturing tolerances and does not prevent functional substitution. Circuit designs with current-limiting resistors accommodate this variation. Verify that existing resistor values maintain target current (20mA) with 2V forward voltage if precise current control is critical.

Q: Can Gull Wing package (SSL-LXA228SYC-TR11) be used in place of Z-Bend package (AM2520YC09)?

A: Both are surface mount configurations with identical footprint dimensions (2.50mm L x 2.00mm W). Gull Wing lead geometry differs from Z-Bend but both are compatible with standard SMD assembly equipment. Verify solder paste stencil design and reflow profile compatibility with your manufacturing process.

Q: Is SSL-LXA228SOC-TR11 (orange) suitable as a substitute for yellow indication applications?

A: No, unless application requirements explicitly permit orange color substitution. Wavelength difference (620nm orange vs 590nm yellow) produces visually distinct indication. Use only when color distinction is not functionally required or when orange indication is acceptable per system specification.

Q: What is the brightness difference between AM2520YC09 (50mcd) and SSL-LXA228SYC-TR31 (250mcd)?

A: SSL-LXA228SYC-TR31 provides 5x higher brightness output. This may require resistor adjustment to maintain equivalent perceived intensity or to prevent over-brightness in the application. Verify that increased brightness does not create glare or exceed design specifications for indicator visibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AM2520YC09 and all three substitute parts (SSL-LXA228SOC-TR11, SSL-LXA228SYC-TR11, SSL-LXA228SYC-TR31) are ROHS3 compliant. All parts are REACH unaffected and classified as EAR99 for export purposes.

Q: What packaging format differences exist between AM2520YC09 and substitutes?

A: AM2520YC09 is supplied in Cut Tape (CT) and Digi-Reel® formats. All Lumex substitutes are supplied in Tape & Reel (TR) format. Verify that your procurement and assembly processes accommodate TR packaging, or confirm availability in alternative packaging formats.
