Engineering Selection Recommendations

Primary Substitute: XHGAWT-00-0000-00000HXE6

This CreeLED XLamp® XH-G component is the qualified substitute for the obsolete Samsung LM231A SPMWHT221MD5WAU0S0. Selection is based on the following engineering criteria:

Electrical Compatibility: The substitute operates at 2.9V typical forward voltage versus 2.86V for the original part—a 0.04V difference that is negligible in practical circuit applications. Both components are specified for 65mA test current and deliver luminous flux within the acceptable range at this operating point. The substitute's 29lm output at 25°C exceeds the original 25lm specification while remaining within the original part's tolerance band (20-30lm), indicating improved manufacturing consistency or enhanced LED die performance.

Thermal and Reliability: Both parts maintain identical thermal resistance of 20°C/W. The substitute's higher maximum current rating (350mA vs. 150mA) provides additional thermal margin and operational flexibility without compromising reliability at the standard 65mA operating point.

Compliance and Regulatory Status: Both components are RoHS Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. The substitute is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Mechanical Considerations: The substitute uses a 1212 (3030 Metric) package versus the original 0909 (2323 Metric) package. This represents a size upgrade with footprint dimensions of 3.00mm x 3.00mm (versus 2.30mm x 2.30mm) and seated height of 1.83mm (versus 0.80mm). PCB layout verification is required to confirm adequate clearance for the taller component. If space constraints prohibit the larger package, alternative CreeLED XLamp® XH-G variants (XHGAWT-00-0000-00000BXE8, XHGAWT-00-0000-00000HXE7, XHGAWT-00-0000-00000BXE7) should be evaluated for package compatibility.

Availability: The substitute is available in active inventory (1673 Pcs New Original In Stock) versus the original part's obsolete status with limited remaining stock (996 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the XHGAWT-00-0000-00000HXE6 be used as a direct drop-in replacement for the SPMWHT221MD5WAU0S0?

A: Electrical compatibility is confirmed at the 65mA operating point. However, the larger package footprint (3030 vs. 2323 Metric) and increased seated height (1.83mm vs. 0.80mm) require PCB layout verification. Direct drop-in replacement is possible only if the PCB design accommodates the larger component dimensions and clearance requirements.

Q: What is the significance of the 0.04V difference in forward voltage between the two parts?

A: The 0.04V difference (2.86V vs. 2.9V) is within typical manufacturing tolerances for LED components and does not affect circuit functionality. Standard LED driver circuits and current-limiting resistor designs accommodate this variation without modification.

Q: Why does the substitute deliver higher luminous flux (29lm vs. 25lm) at the same test current?

A: The higher flux output reflects improvements in LED die efficiency or manufacturing process enhancements in the CreeLED XLamp® XH-G series compared to the Samsung LM231A series. Both values fall within acceptable operating ranges for warm white 3500K LEDs at 65mA. The substitute's improved efficiency (154 lm/W vs. 134 lm/W) indicates better energy conversion.

Q: Are there other CreeLED alternatives if the 3030 package is too large for my application?

A: The substitute list includes XHGAWT-00-0000-00000BXE8, XHGAWT-00-0000-00000HXE7, and XHGAWT-00-0000-00000BXE7 variants within the same XLamp® XH-G series. These alternatives should be evaluated for package size, thermal characteristics, and electrical specifications to determine suitability for space-constrained applications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the original Samsung LM231A and the CreeLED XLamp® XH-G substitute are RoHS Compliant, REACH Unaffected, and classified as EAR99 for export control. Compliance documentation is equivalent for both components.

Q: What is the impact of the wider viewing angle (130° vs. 120°) on system performance?

A: The substitute's 130° viewing angle provides a 10° wider beam distribution compared to the original 120° specification. This results in slightly broader light coverage but may reduce peak intensity in the forward direction. System-level photometric analysis is recommended if precise beam distribution is critical to application performance.

Q: How should I verify PCB clearance for the taller substitute component?

A: The substitute's seated height of 1.83mm is 2.3 times greater than the original 0.80mm height. Measure clearance above the component to adjacent PCB features, solder mask, conformal coating, or enclosure elements. Verify that the increased height does not interfere with assembly processes, testing fixtures, or final product packaging.

Q: Is the higher maximum current rating (350mA vs. 150mA) relevant for my application?

A: The maximum current rating defines the component's thermal and reliability limits. At the standard 65mA operating point, both parts perform identically. The substitute's higher rating provides additional operational margin and may enable future design flexibility if increased brightness is required through higher drive currents.
