Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs and Replacements):

All three substitute parts—SPMWH3228FD5WAP0SC, SPMWH3228FD5WAPKSC, and SPMWH3228FD5WAPMSC—are direct parametric equivalents of the SPMWH3228FD5WAP0S2. These substitutes are preferred because:

1. Active Product Status: All substitute parts carry "Active" product status, ensuring long-term availability and manufacturing support, unlike the main part which is marked "Not For New Designs."

2. Identical Optical and Mechanical Specifications: All substitutes maintain the same 6500K color temperature, 80 CRI, 120° viewing angle, and 1113 (2835 metric) package dimensions, ensuring drop-in compatibility in existing PCB layouts.

3. Improved Efficiency: The LM281BZ+ series substitutes deliver 131 lm/W compared to 127 lm/W for the original LM281BZ, representing a 3.1% efficiency improvement while maintaining identical lumen output (59 lm at 150mA).

4. Lower Forward Voltage: The substitutes operate at 3.0V typical forward voltage versus 3.1V for the main part, reducing power dissipation by approximately 3.2% at 150mA test current.

5. Compliance Alignment: All substitutes maintain RoHS compliance, 2A MSL rating, and identical thermal resistance (25°C/W), ensuring compatibility with existing supply chain and environmental requirements.

Selection Criteria by Application Context:

• For production environments requiring maximum inventory availability, SPMWH3228FD5WAP0SC (1114 units) or SPMWH3228FD5WAPMSC (973 units) are preferred.
• For applications where forward voltage sensitivity is critical, the 3.0V rating of all substitutes provides a 0.1V reduction compared to the original 3.1V specification.
• All three substitutes are electrically and mechanically interchangeable with the SPMWH3228FD5WAP0S2 within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAP0SC, SPMWH3228FD5WAPKSC, and SPMWH3228FD5WAPMSC be used as direct replacements for SPMWH3228FD5WAP0S2?

A: Yes. All three substitute parts are parametric equivalents. They maintain identical color temperature (6500K), CRI (80), package dimensions (2835 metric / 1113 case), viewing angle (120°), thermal resistance (25°C/W), and current ratings (150mA test, 160mA maximum). The substitutes are mechanically and electrically compatible for direct PCB substitution.

Q: What is the difference between the LM281BZ and LM281BZ+ series?

A: The LM281BZ+ series (all three substitutes) represents an improved generation offering higher luminous efficacy (131 lm/W versus 127 lm/W) and lower forward voltage (3.0V versus 3.1V) while maintaining identical optical output (59 lm at 150mA) and all mechanical specifications. The LM281BZ+ series carries active product status, ensuring continued manufacturing support.

Q: Are there any differences in packaging or handling between the main part and substitutes?

A: No. All parts share identical package specifications: 1113 (2835 metric), 3.50mm × 2.80mm footprint, 0.75mm maximum seated height, surface mount mounting type, and 2A MSL (4 weeks) moisture sensitivity level. Handling, storage, and reflow procedures are identical.

Q: Why does the main part carry "Not For New Designs" status?

A: The SPMWH3228FD5WAP0S2 (LM281BZ series) has reached end-of-life status. Samsung Semiconductor recommends transitioning to the LM281BZ+ series (represented by the three substitute parts) for new designs and long-term production continuity. All substitutes carry "Active" status.

Q: What is the impact of the 0.1V forward voltage difference on circuit design?

A: The substitutes operate at 3.0V typical forward voltage compared to 3.1V for the main part. This 0.1V reduction decreases power dissipation by approximately 3.2% at 150mA test current. For series-connected LED strings, this may reduce total voltage drop by 0.1V per LED. Existing current-limiting resistor calculations should be verified for optimal performance, though the difference is typically negligible in most lighting applications.

Q: Do all three substitute parts have identical electrical performance?

A: Yes. SPMWH3228FD5WAP0SC, SPMWH3228FD5WAPKSC, and SPMWH3228FD5WAPMSC are electrically identical. All three deliver 59 lm at 25°C with 150mA test current, 131 lm/W efficiency, 3.0V forward voltage, and 80 CRI. The part number suffixes reflect different packaging or distribution configurations, not electrical differences.

Q: Are these substitutes suitable for high-volume production?

A: Yes. All three substitutes carry "Active" product status with substantial inventory availability (614–1114 units reported). Samsung Semiconductor's active support for the LM281BZ+ series ensures consistent supply and manufacturing continuity for high-volume applications.

Q: What compliance certifications apply to the substitute parts?

A: All substitute parts maintain RoHS compliance and carry identical MSL 2A (4 weeks) moisture sensitivity ratings. ECCN and HTSUS classifications are identical to the main part (EAR99 and 8541.41.0000 respectively).
