APD3224EC-F01 Equivalent & Substitute Parts

Part Overview

The APD3224EC-F01 is an active status red LED indicator manufactured by Kingbright, designed for surface mount applications in discrete indication circuits. This component operates at 2V forward voltage with a 20mA test current and delivers 60mcd luminous intensity through a clear domed lens. The part is ROHS3 compliant and maintains active product status with 686 units in current inventory stock.

Substitute parts are identified to address supply chain continuity, inventory availability, or specific application requirements where equivalent electrical and mechanical parameters are maintained within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APD3224EC-F01 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Forward voltage (Vf): 2V nominal
• Test current: 20mA
• Color specification: Red
• Lens transparency: Clear
• Peak wavelength range: Red spectrum (620–640nm acceptable)

Mechanical Compatibility Parameters:

• Mounting type: Surface Mount (SMD)
• Package footprint: 1210 (3225 Metric) or 1209 (3224 Metric) with equivalent land pattern dimensions (3.20mm L × 2.40mm W)
• Height constraint: Maximum 2.70mm
• Lens style: Round with domed top

Regulatory & Environmental Parameters:

• RoHS3 compliance required
• MSL rating: 3 or better
• REACH unaffected status

The substitute part SML-LXL1209SIC-TR meets all electrical and mechanical compatibility criteria while maintaining regulatory compliance.

Engineering Selection Recommendations

Primary Part: APD3224EC-F01

Select the APD3224EC-F01 when:

• Original design specification requires Kingbright sourcing
• Exact 60mcd luminous intensity is required
• Restricted height budget of 2.40mm maximum is critical
• Bulk packaging format is required
• 20° viewing angle specification is mandatory

Substitute Part: SML-LXL1209SIC-TR

Select the SML-LXL1209SIC-TR when:

• Supply chain constraints limit APD3224EC-F01 availability
• Higher luminous intensity (600mcd) is acceptable or beneficial
• Wider viewing angle (30°) is compatible with application requirements
• Height tolerance permits 2.70mm maximum dimension
• Tape & Reel packaging format is compatible with assembly process
• Lumex Opto/Components Inc. sourcing is acceptable

Both parts maintain ROHS3 compliance, MSL 3 rating, and active product status. The substitute part delivers enhanced optical performance (10× brightness increase) and wider viewing angle while maintaining electrical compatibility at 2V forward voltage and 20mA test current.

Frequently Asked Questions (FAQ)

Q: Can SML-LXL1209SIC-TR directly replace APD3224EC-F01 on existing PCB layouts?

A: The footprint dimensions (3.20mm L × 2.40mm W) are identical, enabling direct land pattern compatibility. However, verify that the 0.30mm height increase (2.70mm vs. 2.40mm maximum) does not violate clearance constraints in your specific assembly. Package case designations (1210 vs. 1209) refer to metric equivalents with compatible solder pad geometry.

Q: What is the impact of the 600mcd vs. 60mcd brightness difference?

A: The SML-LXL1209SIC-TR delivers 10 times greater luminous intensity. This is acceptable in applications where brightness margin is beneficial or where the original 60mcd specification included design margin. If exact brightness matching is required for color consistency or visual uniformity in multi-LED arrays, the original APD3224EC-F01 is required.

Q: Are the wavelength specifications (627nm vs. 636nm) visually distinguishable?

A: Both wavelengths fall within the red spectrum. The 9nm difference is within standard red LED manufacturing tolerance and produces no perceptible color shift to human vision in typical indication applications.

Q: What is the difference between bulk and Tape & Reel packaging?

A: APD3224EC-F01 is supplied in bulk format suitable for manual or small-batch assembly. SML-LXL1209SIC-TR is supplied in Tape & Reel (TR) format optimized for automated pick-and-place assembly. Verify your assembly process compatibility before selecting based on packaging format.

Q: Do both parts require identical reflow soldering profiles?

A: Both parts are surface mount components with MSL 3 rating (168-hour moisture sensitivity). Reflow soldering parameters are determined by solder paste and PCB design rather than LED component specifications. Consult your assembly process documentation for MSL 3 component handling requirements.

Q: Is the 30° viewing angle of the substitute part compatible with 20° specification applications?

A: A wider viewing angle (30°) is a superset of narrower angle requirements (20°). The substitute part will function in any application designed for 20° viewing angle. However, if the original design intentionally specified 20° to limit off-axis visibility, the wider angle may not meet those constraints.
