Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT221MD5WAVMS0 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color and correlated color temperature (CCT): White, Warm 3000K
• Luminous flux at 25°C and 65mA test current: 25 lm nominal (acceptable range 20–30 lm)
• Forward voltage (typical): 2.86V ±0.1V tolerance
• Test current: 65 mA
• CRI: 80 minimum
• Thermal resistance: 20°C/W

Secondary Compatibility Criteria:

• Mounting type: Surface mount
• Package footprint compatibility or functional equivalence
• Maximum current rating: ≥150 mA
• RoHS and REACH compliance status

The XHGAWT-00-0000-00000HWE7 from CreeLED meets these criteria with equivalent electrical performance and active product status, making it a direct functional substitute despite package size differences (3030 vs. 2323 metric).

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Substitution:

The XHGAWT-00-0000-00000HWE7 provides electrical equivalence to the obsolete SPMWHT221MD5WAVMS0. Both components deliver 25 lumens at 65mA test current with 3000K warm white color temperature and 80 CRI. Forward voltage differs by 0.04V (2.86V vs. 2.9V), which is within typical circuit tolerance for LED driver designs. Both parts maintain 20°C/W thermal resistance and comply with RoHS and REACH requirements.

Package Footprint Consideration:

The substitute part uses a larger 3030 metric package (3.00 × 3.00 mm) compared to the original 2323 metric package (2.30 × 2.30 mm), with increased height (1.83 mm vs. 0.80 mm). PCB layout modification is required for mechanical accommodation. The wider 130° viewing angle of the substitute provides enhanced light distribution compared to the original 120° specification.

Active Product Status Advantage:

The XHGAWT-00-0000-00000HWE7 maintains active product status with CreeLED, ensuring continued availability, technical support, and supply chain stability. The original LM231A series is obsolete, making this substitute the appropriate choice for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the XHGAWT-00-0000-00000HWE7 directly replace the SPMWHT221MD5WAVMS0 in existing PCB designs?

A: Electrical substitution is direct. However, the larger package footprint (3030 vs. 2323 metric) and increased height (1.83 mm vs. 0.80 mm) require PCB layout modification. The component cannot be placed in the original footprint without redesign.

Q: What is the impact of the 0.04V forward voltage difference (2.86V vs. 2.9V)?

A: This difference is negligible for most LED driver circuits. Standard current-regulated drivers maintain constant current regardless of forward voltage variation within this range. Voltage-regulated designs should verify the driver's tolerance band, typically ±0.1V or greater.

Q: Are the luminous flux specifications compatible?

A: Yes. Both parts specify 25 lumens at 65mA test current at 25°C. The XHGAWT-00-0000-00000HWE7 has a tighter flux range (24–27 lm) compared to the original (20–30 lm), indicating improved consistency.

Q: Does the wider viewing angle (130° vs. 120°) affect circuit performance?

A: The wider viewing angle provides broader light distribution, which is generally beneficial for general illumination applications. Applications requiring narrow beam concentration may need optical design review.

Q: Are both parts compliant with regulatory requirements?

A: Yes. Both the SPMWHT221MD5WAVMS0 and XHGAWT-00-0000-00000HWE7 are RoHS Compliant and REACH Unaffected, meeting standard regulatory requirements for electronic components.

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

A: The substitute part has a 350mA maximum rating versus 150mA for the original. This higher rating provides design margin and allows operation at higher currents if circuit requirements change. Standard operation at 65mA test current is unaffected.

Q: Is the 20°C/W thermal resistance equivalent between both parts?

A: Yes. Both parts specify identical thermal resistance, ensuring equivalent thermal performance in circuit designs. Heat dissipation characteristics remain unchanged.
