Key Parameters

Substitute Part Grouping Explanation

The XD16AWT-H0-0000-00000HE8E qualifies as a functional substitute based on the following alignment criteria:

Matching Parameters:

• Color and CCT: Both White, Warm 2700K
• Package / Case: Both 0606 (1616 Metric)
• Mounting Type: Both Surface Mount
• Test Current: Both 350mA
• Size / Dimension: Both 0.063" L x 0.063" W (1.60mm x 1.60mm)
• REACH Status: Both REACH Unaffected

Allowable Variations:

• Voltage - Forward (Vf): 3.1V (main) vs. 2.73V (substitute) — lower forward voltage reduces power dissipation
• Flux Output: 84lm @ 25°C (main) vs. 118lm @ 85°C (substitute) — higher efficiency in substitute
• Lumens/Watt: 77 lm/W (main) vs. 123 lm/W (substitute) — improved efficiency
• CRI: 85 (main) vs. 80 (substitute) — acceptable variance for warm white applications
• Viewing Angle: 145° (main) vs. 135° (substitute) — minor angular difference
• Height - Seated: 0.065" (main) vs. 0.035" (substitute) — lower profile in substitute
• Thermal Resistance: 7.5°C/W (main) vs. 6°C/W (substitute) — improved thermal performance
• Current - Max: 700mA (main) vs. 2A (substitute) — higher maximum rating in substitute
• Product Status: Obsolete (main) vs. Active (substitute) — substitute remains in active production

Parameter Comparison

Engineering Selection Recommendations

The XD16AWT-H0-0000-00000HE8E is a direct substitute for the obsolete XQDAWT-02-0000-00000P9E8 in applications requiring warm white 2700K LEDs in 0606 (1616 Metric) surface mount packages.

Compliance Advantages:

• The substitute maintains REACH Unaffected status, matching the original part
• The substitute is RoHS Compliant, providing enhanced regulatory alignment for new designs and production runs
• Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications

Performance Considerations:

• The substitute operates at lower forward voltage (2.73V vs. 3.1V), reducing circuit power dissipation by approximately 12%
• The substitute delivers higher luminous flux (118lm vs. 84lm) and efficiency (123 lm/W vs. 77 lm/W), providing superior light output at identical test current
• The substitute features improved thermal resistance (6°C/W vs. 7.5°C/W), enabling better heat dissipation in constrained thermal environments
• The substitute has a lower seated height (0.035" vs. 0.065"), accommodating tighter PCB assembly clearances

Design Integration:

• Identical package footprint and mounting type ensure direct PCB compatibility without layout modifications
• Identical color temperature (2700K) and acceptable CRI variance (80 vs. 85) maintain color consistency in warm white applications
• Slightly reduced viewing angle (135° vs. 145°) requires verification in applications with critical angular distribution requirements

Frequently Asked Questions (FAQ)

Q: Can the XD16AWT-H0-0000-00000HE8E directly replace the XQDAWT-02-0000-00000P9E8 on existing PCBs?

A: Yes. Both parts share identical package dimensions (0606 / 1616 Metric), footprint, and mounting type (Surface Mount). No PCB layout modifications are required. The lower forward voltage of the substitute may require circuit current-limiting adjustments to maintain identical brightness levels.

Q: What is the impact of the 0.37V forward voltage difference?

A: The substitute operates at 2.73V versus the original 3.1V. This 12% reduction in forward voltage decreases power dissipation per LED. Existing current-limiting circuits designed for 3.1V will deliver the same 350mA test current to the substitute, but at lower power consumption. Verify that your circuit topology accommodates this voltage shift without affecting overall system performance.

Q: Are there differences in color rendering between these parts?

A: Both parts are warm white 2700K. The original has CRI 85; the substitute has CRI 80. This 5-point difference is within acceptable tolerance for warm white applications and will not produce perceptible color shifts in typical lighting scenarios. Applications requiring CRI ≥ 85 should evaluate this variance against specific requirements.

Q: How does the viewing angle difference affect application compatibility?

A: The original provides 145° viewing angle; the substitute provides 135°. This 10° reduction narrows the light distribution cone slightly. Applications requiring wide-angle diffusion should verify that 135° meets optical design requirements. Most general-purpose warm white lighting applications tolerate this variance.

Q: What is the significance of the lower seated height in the substitute?

A: The substitute is 0.030" (0.77mm) shorter when seated (0.035" vs. 0.065"). This lower profile reduces overall assembly height, beneficial for space-constrained designs. Verify that your PCB assembly process and thermal management design accommodate the lower component height without affecting solder joint quality or thermal performance.

Q: Is the substitute suitable for new production designs?

A: Yes. The substitute is Active status with RoHS Compliance, making it appropriate for new designs and long-term production. The original part is Obsolete and should not be specified for new designs. The substitute provides superior efficiency and thermal performance compared to the original.

Q: What is the maximum current rating for each part?

A: The original supports 700mA maximum; the substitute supports 2A maximum. Both are tested and specified at 350mA. The substitute's higher maximum rating provides additional design margin for applications requiring occasional current peaks or future performance upgrades.
