LED LM231A COOL WHITE 6500K 2323 (SPMWHT221MD5WAP0S0) - Equivalent & Substitute Parts

Part Overview

The Samsung Semiconductor LM231A is a surface-mount LED lighting component featuring cool white 6500K color temperature in a compact 0909 (2323 metric) package. This part is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing design support and procurement continuity. The LM231A delivers 26 lumens at 25°C under 65mA test current with a forward voltage of 2.95V and 120° viewing angle, suitable for applications requiring high color rendering index (CRI 80) illumination in space-constrained assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Samsung LM231A is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Color specification: White, Cool white at 6500K color temperature
• Luminous flux range: Minimum 21 lumens at 25°C under 65mA test current
• Forward voltage compatibility: 2.9V to 2.95V typical range
• Test current: 65mA nominal operation
• Color Rendering Index: CRI 80 or higher
• Thermal resistance: 20°C/W package thermal performance
• Compliance: RoHS compliant, REACH unaffected status
• Mounting: Surface mount technology

The CreeLED XLamp® XH-G series component XHGAWT-00-0000-00000HXE1 meets all substitution criteria. While the package footprint differs (1212/3030 metric versus 0909/2323 metric), the electrical performance parameters and compliance certifications align with the LM231A specifications, enabling functional equivalence in applications where PCB layout can accommodate the larger package geometry.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Electrical Compatibility):

The CreeLED XLamp® XH-G XHGAWT-00-0000-00000HXE1 is electrically compatible with the Samsung LM231A. Both components operate at identical test current (65mA), deliver luminous flux within overlapping ranges at 25°C, maintain equivalent forward voltage characteristics (2.9V vs. 2.95V), and share identical CRI (80) and thermal resistance (20°C/W) specifications. Both components carry RoHS compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

For PCB Layout Considerations:

The CreeLED substitute requires PCB footprint modification. The XLamp® XH-G occupies a 1212 (3030 metric) package footprint measuring 3.00mm × 3.00mm with 1.83mm maximum seated height, compared to the LM231A's 2.30mm × 2.30mm footprint with 0.80mm height. Design layouts with space constraints may require component repositioning or board redesign to accommodate the larger package geometry.

Product Status Advantage:

The CreeLED XLamp® XH-G series maintains active product status with 31,764 units in stock, providing long-term procurement availability and supply chain continuity. The Samsung LM231A is classified as obsolete with limited remaining inventory (962 units), making the active substitute preferable for new designs and ongoing production support.

Performance Enhancement:

The CreeLED substitute delivers 154 lm/W efficiency versus the LM231A's 140 lm/W, representing 10% improved luminous efficacy at identical test current. The wider 130° viewing angle (versus 120°) provides expanded light distribution characteristics. Maximum current rating of 350mA (versus 150mA) offers greater operational headroom for thermal management in high-brightness applications.

Frequently Asked Questions (FAQ)

Q: Can the CreeLED XLamp® XH-G directly replace the Samsung LM231A without circuit modification?

A: Electrical substitution is direct. Both components operate at 65mA test current with compatible forward voltages (2.9V vs. 2.95V), identical CRI (80), and matching thermal resistance (20°C/W). No circuit redesign is required. However, PCB layout modification is necessary due to package footprint differences (3030 metric versus 2323 metric).

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is determined by: color temperature (6500K cool white), luminous flux range (21–31 lumens at 25°C, 65mA), forward voltage (2.9–2.95V), test current (65mA), CRI (80), thermal resistance (20°C/W), and compliance certifications (RoHS compliant, REACH unaffected, EAR99 ECCN).

Q: Does the larger package size of the CreeLED substitute affect electrical performance?

A: No. Package size differences do not alter electrical performance. Both components maintain identical thermal resistance (20°C/W), forward voltage compatibility, and luminous flux characteristics. Package size affects only PCB layout and mechanical integration, not electrical operation.

Q: Is the CreeLED substitute suitable for space-constrained applications?

A: The CreeLED XLamp® XH-G is not recommended for applications with strict space limitations. The 3030 metric package (3.00mm × 3.00mm, 1.83mm height) is significantly larger than the LM231A's 2323 metric package (2.30mm × 2.30mm, 0.80mm height). Applications requiring minimal footprint should retain the LM231A or identify alternative compact-package solutions.

Q: What is the inventory status difference between the main part and substitute?

A: The Samsung LM231A (obsolete status) has 962 units in stock. The CreeLED XLamp® XH-G (active status) has 31,764 units available. The substitute offers significantly greater procurement availability and long-term supply chain security.

Q: Are there compliance or regulatory differences between the two components?

A: No. Both components are RoHS compliant, REACH unaffected, classified under EAR99 ECCN, and share identical HTSUS code (8541.41.0000). Regulatory and compliance requirements are equivalent.

Q: How does the viewing angle difference (120° vs. 130°) affect application suitability?

A: The CreeLED substitute's wider 130° viewing angle provides broader light distribution compared to the LM231A's 120° angle. This difference is advantageous for applications requiring wider illumination coverage but may require optical design adjustment if the original design relied on the narrower 120° beam pattern.

Q: What is the efficiency improvement of the CreeLED substitute?

A: The CreeLED XLamp® XH-G delivers 154 lm/W versus the LM231A's 140 lm/W at identical 65mA test current, representing 10% improved luminous efficacy. This efficiency gain reduces power consumption for equivalent light output.
