Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWH3228FD5WAPKS2 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Color: White, Cool (6500K)
• CCT: 6500K
• Flux @ 25°C, 150mA: 59 lm (57–61 lm range)
• Current - Test: 150 mA
• Viewing Angle: 120°
• Package / Case: 1113 (2835 Metric)
• Mounting Type: Surface Mount
• CRI: 80
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Allowable Variation:

• Voltage - Forward (Vf) Typical: 3.0V to 3.1V (minor reduction acceptable within forward voltage tolerance)
• Lumens/Watt: Improvement from 127 lm/W to 131 lm/W (efficiency gain)
• Product Status: Active status preferred over "Not For New Designs"
• Series: LM281BZ+ (enhanced variant of LM281BZ base series)

All three substitute parts meet these criteria and maintain full electrical and mechanical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SPMWH3228FD5WAPMSC

This part offers the highest current inventory (973 pcs) while maintaining full parametric equivalence. Active product status ensures ongoing manufacturing support and supply chain continuity. The 0.1V reduction in forward voltage (3.0V vs. 3.1V) falls within standard LED forward voltage tolerance and results in improved efficiency (131 lm/W vs. 127 lm/W).

Secondary Recommendations: SPMWH3228FD5WAPKSC and SPMWH3228FD5WAP0SC

Both alternatives provide active product status with identical electrical and optical performance. SPMWH3228FD5WAPKSC maintains 614 pcs inventory, while SPMWH3228FD5WAP0SC provides 1114 pcs. Selection between these two depends on packaging requirements and supply chain logistics.

Compliance Considerations:

All substitute parts maintain RoHS compliance and MSL 2A (4 Weeks) rating, ensuring compatibility with standard PCB assembly processes and storage protocols. No additional handling or qualification is required.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAPMSC replace SPMWH3228FD5WAPKS2 in existing designs?

A: Yes. Both parts share identical optical output (59 lm at 6500K), viewing angle (120°), package (2835 metric), and CRI (80). The 0.1V forward voltage difference (3.0V vs. 3.1V) is within standard LED tolerance and does not affect circuit operation.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This designation indicates the SPMWH3228FD5WAPKS2 is in mature/legacy phase. Substitute parts with "Active" status provide access to current manufacturing, extended lead times, and ongoing technical support.

Q: Are there mechanical differences between the main part and substitutes?

A: No. All parts use identical 1113 (2835 metric) package dimensions: 3.50mm L × 2.80mm W × 0.75mm H maximum seated height. Surface mount compatibility is identical.

Q: How does the improved efficiency (131 lm/W vs. 127 lm/W) affect circuit design?

A: The efficiency improvement reflects enhanced LED technology in the LM281BZ+ series. At constant 150mA test current, this results in identical 59 lm output. No circuit redesign is required.

Q: What is the impact of forward voltage reduction from 3.1V to 3.0V?

A: The 0.1V reduction is within typical LED forward voltage tolerance (±0.1V). For constant-current driver circuits, this change has no impact. For resistive current limiting, recalculation of series resistance may optimize efficiency but is not required for functionality.

Q: Are all substitute parts available in the same packaging format?

A: Packaging format information is not provided for substitute parts in the input data. Confirm packaging (Tape & Reel vs. alternative formats) with supplier before procurement if packaging specification is critical.

Q: Which substitute part should be selected for maximum supply availability?

A: SPMWH3228FD5WAPMSC offers the highest inventory (973 pcs), followed by SPMWH3228FD5WAP0SC (1114 pcs). Both ensure immediate availability for production requirements.
