LED LM231A SPMWHT221MD5WAUMS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT221MD5WAUMS0 is a Samsung Semiconductor warm white LED (LM231A series) designed for surface mount lighting applications. This component operates at 3500K color temperature with a typical forward voltage of 2.86V and test current of 65mA, delivering 25 lumens at 25°C. The part is classified as obsolete, making equivalent substitute components necessary for ongoing production and maintenance applications requiring warm white LED solutions in compact 0909 (2323 metric) packages.

Substitute Part Grouping Explanation

Substitution of the SPMWHT221MD5WAUMS0 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color specification: White, Warm
• Correlated Color Temperature (CCT): 3500K
• Color Rendering Index (CRI): 80 minimum
• Test current compatibility: 65mA operation
• Forward voltage range: 2.86V nominal (acceptable tolerance ±0.1V)
• Mounting type: Surface Mount
• Thermal resistance: 20°C/W

Secondary Compatibility Factors:

• Package form factor: 0909 (2323 metric) or larger compatible packages
• Viewing angle: 120° minimum
• Lumens output: 25lm nominal at 25°C, 65mA (acceptable range 20–30lm)
• Compliance: RoHS Compliant, REACH Unaffected

The substitute part XHGAWT-00-0000-00000HXE6 (CreeLED XLamp® XH-G series) meets these criteria with equivalent electrical performance and enhanced mechanical specifications.

Engineering Selection Recommendations

Substitution Feasibility:

The XHGAWT-00-0000-00000HXE6 (CreeLED XLamp® XH-G) is a valid electrical and functional substitute for the obsolete SPMWHT221MD5WAUMS0. Both components deliver identical color temperature (3500K), CRI (80), and operate at the same test current (65mA) with compatible forward voltages (2.86V vs. 2.9V).

Compliance Status:

Both components are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for electronic component substitution. The CreeLED part carries Active product status, ensuring long-term availability and supply chain continuity.

Physical Considerations:

The substitute part uses a larger 1212 (3030 metric) package compared to the original 0909 (2323 metric) package. This represents a footprint increase from 2.30mm × 2.30mm to 3.00mm × 3.00mm, with height increasing from 0.80mm to 1.83mm. PCB layout and mechanical clearance verification is required before implementation.

Performance Enhancement:

The CreeLED substitute delivers superior luminous efficacy (154 lm/W vs. 134 lm/W) and higher maximum current rating (350mA vs. 150mA), providing design flexibility for future power optimization or brightness adjustment without component replacement.

Frequently Asked Questions (FAQ)

Q1: Can the XHGAWT-00-0000-00000HXE6 be used as a direct drop-in replacement for SPMWHT221MD5WAUMS0?

A: Electrical substitution is valid. Both components operate at 3500K, 80 CRI, 65mA test current, and compatible forward voltages. However, the substitute uses a larger package (3030 vs. 2323 metric). PCB layout modification is required if the original footprint cannot accommodate the larger dimensions (3.00mm × 3.00mm vs. 2.30mm × 2.30mm).

Q2: What are the key parameters that determine substitution compatibility?

A: Substitution is based on: color temperature (3500K), CRI (80), test current (65mA), forward voltage (2.86–2.9V range), mounting type (surface mount), and compliance certifications (RoHS, REACH). Package size is a secondary consideration that depends on PCB design constraints.

Q3: Are there electrical performance differences between the original and substitute?

A: The substitute delivers higher luminous efficacy (154 lm/W vs. 134 lm/W) and slightly higher flux output (29lm vs. 25lm at 65mA). Forward voltage is marginally higher (2.9V vs. 2.86V). These differences are within acceptable engineering tolerances for warm white LED applications.

Q4: What is the impact of the larger package size?

A: The 3030 metric package is 0.70mm larger in length and width, and 1.03mm taller than the original 2323 package. This affects PCB layout, component spacing, and mechanical clearance. Verify that the application PCB can accommodate these dimensions before substitution.

Q5: Is the substitute part readily available?

A: Yes. The XHGAWT-00-0000-00000HXE6 carries Active product status with 1673 units in stock, compared to the obsolete SPMWHT221MD5WAUMS0 (820 units remaining). The substitute ensures long-term supply chain continuity.

Q6: Do both parts meet the same regulatory requirements?

A: Yes. Both components are RoHS Compliant and REACH Unaffected. No additional compliance verification is required for regulatory substitution.

Q7: Can the substitute handle higher current levels?

A: Yes. The substitute maximum current rating is 350mA compared to 150mA for the original. This allows operation at higher brightness levels if required by the application, though the standard test current remains 65mA for both parts.

Q8: What is the thermal performance comparison?

A: Both components have identical thermal resistance (20°C/W). Thermal management design does not require modification when substituting these parts.
