Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LXA228SIC-TR21 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Color: Red
• Lens Transparency: Clear
• Mounting Type: Surface Mount, Bottom Entry
• Package Configuration: 2-SMD format
• RoHS Compliance: ROHS3 Compliant
• Lens Style: Round with Domed Top

Allowable Variation Parameters:

• Forward Voltage (Vf): Range 1.9V to 2.0V (tolerance for circuit compatibility)
• Millicandela Rating: 475mcd to 1000mcd (brightness variation acceptable for indication applications)
• Viewing Angle: 15° to 50° (application-dependent)
• Wavelength - Peak: 630nm to 650nm (red spectrum range)
• Lens Size: 1.90mm to 1.91mm Dia (negligible mechanical difference)
• Height: 2.90mm to 2.92mm (within PCB clearance tolerance)
• Moisture Sensitivity Level: MSL 2A to MSL 4 (storage condition variation)

Substitute Parts Identified:

• HLMA-QF00-S0031 (Broadcom Limited)

Both substitute parts meet all mandatory compatibility parameters and fall within allowable variation ranges for electrical and optical performance.

Parameter Comparison

Engineering Selection Recommendations

SSL-LXA228SIC-TR21 (Primary Part): Retain as primary selection when 475mcd brightness and 50° viewing angle are circuit requirements. Forward voltage of 2V is suitable for standard 3.3V or 5V logic circuits with appropriate current-limiting resistor. ROHS3 compliance and RoHS Unaffected REACH status confirm regulatory alignment. MSL 4 rating requires standard moisture control during storage and assembly.

AM2520SURCK09 (Kingbright Substitute): Select when higher brightness output (1000mcd) is acceptable or required. Forward voltage of 1.95V provides near-equivalent circuit performance. Narrower viewing angle (20°) restricts light distribution compared to primary part. Identical footprint dimensions (2.50mm L x 2.00mm W, 2.90mm height) ensure direct PCB layout compatibility. Z-Bend configuration differs from Yoke Bend but maintains bottom entry mounting. MSL 3 rating provides extended moisture protection (168 hours) compared to primary part. ROHS3 compliance confirmed.

HLMA-QF00-S0031 (Broadcom Substitute): Select when lowest forward voltage (1.9V) is required for low-power circuit applications. Brightness output (500mcd) exceeds primary part specification. Narrowest viewing angle (15°) concentrates light output for focused indication. Footprint dimensions differ slightly (2.09mm L x 2.92mm W, 2.92mm height) requiring PCB layout verification. Flat Leads configuration differs from Yoke Bend and Z-Bend. Superior moisture protection (MSL 2A, 4 weeks) suitable for high-humidity environments. ROHS3 compliance confirmed.

Frequently Asked Questions (FAQ)

Q: Can AM2520SURCK09 replace SSL-LXA228SIC-TR21 in existing PCB designs?

A: Direct replacement is possible with layout verification. Both parts share identical footprint dimensions (2.50mm L x 2.00mm W, 2.90mm height) and bottom entry mounting configuration. The Z-Bend lead geometry differs from Yoke Bend, requiring confirmation that lead routing and solder pad design accommodate the alternative bend profile. Forward voltage difference (1.95V vs 2V) is negligible for standard logic circuits; circuit current-limiting resistor may require minor adjustment to maintain consistent brightness.

Q: What are the optical performance differences between substitute parts?

A: AM2520SURCK09 provides 1000mcd brightness with 20° viewing angle, delivering concentrated light output suitable for high-visibility indication. HLMA-QF00-S0031 provides 500mcd brightness with 15° viewing angle, offering the most focused light distribution. SSL-LXA228SIC-TR21 provides 475mcd brightness with 50° viewing angle, distributing light across the widest field. Selection depends on application visibility requirements and viewing geometry constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SSL-LXA228SIC-TR21, AM2520SURCK09, and HLMA-QF00-S0031 are all ROHS3 Compliant. All parts are REACH Unaffected or REACH Compliant, confirming regulatory alignment for EU and international markets.

Q: How do moisture sensitivity levels affect component handling?

A: SSL-LXA228SIC-TR21 (MSL 4, 72 hours) requires standard moisture control during storage and assembly. AM2520SURCK09 (MSL 3, 168 hours) provides extended protection, allowing longer shelf life before reflow soldering. HLMA-QF00-S0031 (MSL 2A, 4 weeks) offers superior moisture resistance, suitable for extended storage in non-controlled environments. Higher MSL ratings reduce risk of moisture-induced solder joint failures during reflow.

Q: Can HLMA-QF00-S0031 be used in designs requiring bottom entry configuration?

A: HLMA-QF00-S0031 is specified as Surface Mount without explicit bottom entry designation. While the component features 2-SMD configuration with flat leads, the absence of bottom entry specification indicates potential differences in lead geometry and PCB mounting orientation compared to SSL-LXA228SIC-TR21 and AM2520SURCK09. PCB layout and assembly process verification is required before substitution.

Q: What forward voltage tolerance should be applied for circuit design?

A: Forward voltages range from 1.9V (HLMA-QF00-S0031) to 2V (SSL-LXA228SIC-TR21), representing a 0.1V variation. For standard 3.3V or 5V logic circuits with current-limiting resistors, this variation is within acceptable tolerance and does not require circuit redesign. Verify that the selected current-limiting resistor value maintains acceptable brightness across the forward voltage range of the chosen substitute part.
