Substitute Part Grouping Explanation

Substitution of the SPMWH3228FD5WAPMS3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Color: White, Cool
• CCT: 6500K
• Flux @ 25°C, 150mA: 63 lm (61-65 lm range)
• Test Current: 150mA
• Maximum Current: 160mA
• Viewing Angle: 120°
• Package / Case: 1113 (2835 Metric)
• CRI: 80
• Thermal Resistance: 25°C/W
• RoHS Compliance: Yes
• Moisture Sensitivity Level: 2A (4 Weeks)

The substitute parts identified (SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, SPMWH3228FD5WAPMSE) are all LM281BZ+ series variants from Samsung Semiconductor. These parts maintain identical optical, thermal, and mechanical specifications while operating at a reduced typical forward voltage of 3.0V compared to the main part's 3.1V. This voltage differential remains within acceptable design tolerance for applications originally specified for the SPMWH3228FD5WAPMS3.

Parameter Comparison

Engineering Selection Recommendations

The SPMWH3228FD5WAPMS3 is classified as Not For New Designs. For ongoing production support, the three substitute parts—SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, and SPMWH3228FD5WAPMSE—are all designated as Active products and represent the current production equivalents from Samsung Semiconductor.

All substitute parts maintain full RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring compatibility with existing assembly and storage protocols. The LM281BZ+ series variants deliver improved luminous efficacy (140 lm/W versus 135 lm/W) while maintaining identical optical output (63 lm @ 25°C, 150mA) and color characteristics (6500K, CRI 80).

The forward voltage reduction from 3.1V to 3.0V in the substitute parts results in lower power dissipation per unit, which is beneficial for thermal management in high-density LED applications. This voltage differential is within standard design tolerance for LED driver circuits and does not require circuit modification for direct substitution.

Selection among the three substitute parts may be based on inventory availability and supplier logistics, as all three parts are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, or SPMWH3228FD5WAPMSE be used as direct replacements for SPMWH3228FD5WAPMS3?

A: Yes. All three substitute parts are parametric equivalents with identical optical output (63 lm), color temperature (6500K), CRI (80), viewing angle (120°), and package dimensions (2835 metric). The forward voltage is reduced from 3.1V to 3.0V, which does not require circuit modification for standard LED driver applications.

Q: What is the difference between the three substitute part numbers?

A: SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, and SPMWH3228FD5WAPMSE are all LM281BZ+ variants with identical electrical and optical specifications. The differences in part numbers reflect internal Samsung manufacturing or distribution codes. All three parts are functionally equivalent for substitution purposes.

Q: Why does the substitute part have lower forward voltage (3.0V vs 3.1V)?

A: The LM281BZ+ series represents an improved generation of the LM281BZ LED with enhanced efficiency. The reduced forward voltage results in lower power consumption while maintaining identical light output, representing a design improvement rather than a degradation.

Q: Are there any thermal or reliability differences between the main part and substitutes?

A: No. Thermal resistance (25°C/W), maximum current rating (160mA), and all thermal characteristics are identical. Both the LM281BZ and LM281BZ+ series share the same thermal performance specifications.

Q: What is the inventory status of these substitute parts?

A: SPMWH3228FD5WAP0SE has 911 units in stock, SPMWH3228FD5WAPKSE has 716 units, and SPMWH3228FD5WAPMSE has 727 units available as new original stock.

Q: Do the substitute parts require different PCB layout or assembly procedures?

A: No. The package dimensions (3.50mm x 2.80mm), height (0.75mm maximum), and mounting type (surface mount) are identical. Existing PCB layouts and assembly processes require no modification.

Q: Are moisture sensitivity and storage requirements the same?

A: Yes. All parts carry MSL rating 2A (4 Weeks), requiring identical storage and handling protocols.
