Electrical Equivalence Criteria:

• Series designation (LM281B+)
• Color specification (White, Cool)
• Color temperature (6500K)
• Luminous flux at 25°C and 150mA test current (60 lm, range 58–62 lm)
• Forward voltage (3.1V typical)
• Current ratings (150mA test, 160mA maximum)
• Luminous efficacy (129 lm/W)
• Color Rendering Index (80)

Mechanical Equivalence Criteria:

• Package type (1113 / 2835 Metric)
• Mounting type (Surface Mount)
• Physical dimensions (3.50mm × 2.80mm × 0.75mm max height)
• Viewing angle (120°)
• Thermal resistance (25°C/W)

Compliance Equivalence Criteria:

• RoHS compliance status
• Moisture Sensitivity Level (2A, 4 Weeks)
• ECCN and HTSUS classifications

Parts that maintain all parameters within the specified tolerances and certifications are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SPMWH1228FD5WAP0SA is a direct parametric equivalent to the SPMWH1228FD5WAPMSA. Both parts are manufactured by Samsung Semiconductor, Inc., share identical electrical specifications, mechanical dimensions, and thermal characteristics, and maintain active product status.

The primary distinction between the two parts is the RoHS compliance designation: SPMWH1228FD5WAPMSA carries RoHS Compliant status, while SPMWH1228FD5WAP0SA carries ROHS3 Compliant status. ROHS3 represents an updated compliance framework and is functionally equivalent for applications requiring RoHS certification.

Both parts are suitable for direct substitution in applications requiring cool white 6500K LEDs in the 2835 metric surface mount package. Selection between these parts may be determined by supply availability, inventory levels, or specific compliance documentation requirements. The SPMWH1228FD5WAP0SA currently maintains significantly higher inventory (81,037 pcs) compared to the SPMWH1228FD5WAPMSA (885 pcs).

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAP0SA be used as a direct replacement for SPMWH1228FD5WAPMSA in existing designs?

A: Yes. Both parts are parametrically identical across all electrical, mechanical, and thermal specifications. No circuit modifications or PCB layout changes are required. The parts are pin-compatible and functionally interchangeable.
