Engineering Selection Recommendations

The XHGAWT-00-0000-00000HXE6 is a direct functional substitute for the obsolete SPMWHT221MD5WAUHS0 based on the following engineering criteria:

Electrical Compatibility: Both components operate at identical test current (65mA) and color temperature (3500K). Forward voltage differential is 0.04V (2.86V vs. 2.9V), which is within standard circuit design tolerance for LED applications. Both maintain CRI of 80, ensuring equivalent color rendering performance.

Compliance Status: Both parts carry RoHS Compliant and REACH Unaffected certifications, meeting regulatory requirements for current manufacturing and distribution.

Product Lifecycle: The substitute part (XHGAWT-00-0000-00000HXE6) maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

Physical Considerations: The substitute uses a larger package footprint (1212/3030 Metric vs. 0909/2323 Metric) and increased height (1.83mm vs. 0.80mm). PCB layout and mechanical clearance must be evaluated for specific applications. The larger package provides improved thermal characteristics and higher maximum current rating (350mA vs. 150mA).

Frequently Asked Questions (FAQ)

Q: Can the XHGAWT-00-0000-00000HXE6 be used as a direct drop-in replacement for the SPMWHT221MD5WAUHS0?

A: Electrical substitution is valid based on matching color temperature, test current, and CRI specifications. However, the larger package footprint (3030 vs. 2323 Metric) requires PCB layout modification. Physical clearance and solder pad redesign are necessary before implementation.

Q: What is the impact of the 0.04V forward voltage difference?

A: The forward voltage differential (2.86V vs. 2.9V) is within standard tolerance for LED circuit design. Current-limiting resistor values may require minor adjustment to maintain identical test current (65mA) in the application circuit. Recalculation of series resistance is recommended.

Q: Why does the substitute part have higher lumens output (29lm vs. 25lm)?

A: The XHGAWT-00-0000-00000HXE6 delivers 29 lumens at identical test current (65mA), representing improved efficiency (154 lm/W vs. 134 lm/W). This results in brighter illumination at the same operating current. Application brightness requirements must be evaluated to determine if this increase is acceptable.

Q: Are there package compatibility concerns?

A: Yes. The substitute uses 1212 (3030 Metric) packaging versus the original 0909 (2323 Metric). The larger footprint (3.00mm x 3.00mm vs. 2.30mm x 2.30mm) and increased height (1.83mm vs. 0.80mm) require PCB redesign. Verify mechanical clearance in the target application before component selection.

Q: Do both parts meet current regulatory requirements?

A: Both components are RoHS Compliant and REACH Unaffected. The substitute part maintains active product status, ensuring compliance with current and future regulatory standards. The original part, being obsolete, may face supply chain restrictions.

Q: What is the maximum current rating difference, and does it matter?

A: The substitute supports 350mA maximum current versus 150mA for the original. At the standard 65mA test current, this difference is not operationally significant. The higher rating provides design margin for future applications requiring increased brightness.
