LED LM231A COOL WHITE 5700K 2323 (SPMWHT221MD5WAQMS0) - Equivalent & Substitute Parts

Part Overview

The Samsung Semiconductor LM231A is a surface-mount LED lighting component featuring cool white 5700K 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, production continuity, and component sourcing.

The LM231A delivers 26 lumens at 25°C under 65mA test current with a forward voltage of 2.86V and a 120° viewing angle. With a CRI of 80 and RoHS compliance, this component was designed for general illumination applications requiring cool white spectral output.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Substitution Criteria:

• Color and correlated color temperature (CCT): White, Cool 5700K
• Test current: 65 mA nominal operation
• Forward voltage range: Compatible with 2.86V ± tolerance
• Luminous flux output: Comparable performance at test current (26 lm baseline)
• Color Rendering Index (CRI): 80 or higher
• Viewing angle: 120° or greater
• Mounting type: Surface mount
• Thermal resistance: 20°C/W or lower
• Compliance: RoHS compliant

Secondary Compatibility Factors:

• Package footprint: 0909 (2323 Metric) or larger compatible packages
• Maximum current rating: 150 mA or higher
• Product status: Active or current production preferred for long-term availability

The CreeLED XLamp® XH-G series component listed below meets all primary substitution criteria while offering enhanced performance characteristics within the allowed parameter envelope.

Engineering Selection Recommendations

Substitution Feasibility:

The CreeLED XLamp® XH-G (XHGAWT-00-0000-00000HXE2) qualifies as a functional equivalent for the obsolete Samsung LM231A based on matching electrical specifications at the test current of 65 mA. Both components deliver cool white 5700K output with CRI 80, identical thermal resistance, and full RoHS compliance.

Key Considerations for Design Integration:

1. Footprint Change: The substitute component uses a 1212 (3030 Metric) package versus the original 0909 (2323 Metric). This represents a 30% increase in lateral dimensions and 2.3× increase in height. PCB layout and mechanical clearance must be re-evaluated.

2. Electrical Compatibility: Forward voltage increases from 2.86V to 2.9V (0.04V difference). Current-limiting resistor values in series circuits may require minor adjustment to maintain identical test current operation.

3. Performance Enhancement: The substitute delivers 29 lm versus 26 lm at identical test current, representing 11.5% higher luminous output. Efficiency improves from 140 lm/W to 154 lm/W. Viewing angle widens from 120° to 130°.

4. Availability and Production Status: The substitute is in active production with current inventory, whereas the original part is obsolete. Long-term component sourcing is secured with the substitute.

5. Compliance Certification: Both components maintain identical regulatory status: RoHS compliant, REACH unaffected, EAR99 export classification, and 8541.41.0000 HTSUS code.

Design Validation Requirements:

Thermal management, optical performance, and mechanical fit must be validated in the target application before production implementation. The increased height and footprint may impact thermal dissipation characteristics and optical system design.

Frequently Asked Questions (FAQ)

Q1: Can the CreeLED XLamp® XH-G directly replace the Samsung LM231A without PCB modification?

A: Electrical substitution is feasible at the 65 mA test current with minimal circuit adjustment. However, the package footprint change from 0909 (2323 Metric) to 1212 (3030 Metric) requires PCB layout modification. The substitute component is 30% larger in lateral dimensions and 2.3× taller, necessitating new land pattern design and mechanical clearance verification.

Q2: What is the forward voltage difference, and does it affect circuit design?

A: The substitute forward voltage is 2.9V versus 2.86V for the original, a difference of 0.04V or 1.4%. In series-resistor-limited circuits, this minor increase may require resistor value adjustment to maintain the 65 mA test current. The impact is negligible in constant-current driver applications.

Q3: Why does the substitute have a higher maximum current rating (350 mA vs. 150 mA)?

A: The CreeLED XLamp® XH-G is a higher-performance product line with greater thermal and electrical headroom. The higher maximum current rating reflects the component's capability but does not mandate operation at elevated currents. The 65 mA test current remains the standard operating point for this substitution.

Q4: Does the 11.5% higher luminous output affect optical system design?

A: Yes. The substitute delivers 29 lm versus 26 lm at identical test current. Applications with fixed optical geometry or brightness targets may require circuit current adjustment downward to match original output levels, or optical system redesign to accommodate increased brightness.

Q5: Is the wider 130° viewing angle compatible with the original 120° specification?

A: The wider viewing angle is a performance enhancement that expands the light distribution pattern. Applications requiring narrow beam concentration may need optical redesign. Applications benefiting from broader illumination will see improved performance.

Q6: Are there any compliance or certification concerns with substitution?

A: Both components maintain identical regulatory compliance: RoHS compliant, REACH unaffected, EAR99 export classification, and 8541.41.0000 HTSUS tariff code. No additional certification or compliance documentation is required for the substitution.

Q7: What is the impact of the increased package height (0.80 mm to 1.83 mm)?

A: The 2.3× increase in height may affect thermal dissipation characteristics, mechanical clearance in confined spaces, and optical system geometry. Thermal modeling and mechanical fit verification are required before production implementation.

Q8: Is the CreeLED substitute available in the same packaging format (Tape & Reel)?

A: The substitute is supplied in Tape & Reel (TR) format, consistent with high-volume production requirements. Packaging compatibility is confirmed for automated assembly processes.
