• Voltage - Forward (Vf) (Typ): 3.3V
• Current - Test: 20mA
• Lens Transparency: Clear
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

The APTL3216ZGC from Kingbright meets all mandatory parameters and qualifies as a direct substitute. Both components share identical package dimensions, electrical specifications, and compliance certifications, enabling direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the XZDG55W-2 and APTL3216ZGC are active-status components with identical RoHS3 compliance and REACH unaffected status, qualifying them for equivalent circuit applications. The components share matching electrical characteristics (3.3V forward voltage, 20mA test current) and identical package dimensions (3.20mm L x 1.60mm W), ensuring mechanical and electrical interchangeability on standard PCB layouts.

The APTL3216ZGC exhibits a maximum height of 1.10mm compared to the XZDG55W-2 at 1.25mm, representing a 0.15mm reduction that does not impact standard surface mount assembly processes. The APTL3216ZGC provides higher luminous intensity (1100mcd versus 447mcd) and a narrower viewing angle (70° versus 120°), characteristics that should be evaluated against specific application requirements for brightness and light distribution.

Both components maintain identical moisture sensitivity levels (MSL 3, 168 Hours) and comply with current regulatory frameworks, supporting deployment in equivalent environmental conditions.
