Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1221FD7GBTMSB is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Series: LM282B
• Color: White, Neutral
• CCT: 4000K
• Package / Case: 1113 (2835 Metric)
• Mounting Type: Surface Mount
• Forward Voltage (Vf): 6.3V
• Test Current: 150mA
• Maximum Current: 160mA
• Viewing Angle: 120°
• Physical Dimensions: 3.50mm × 2.80mm
• Height – Seated: 0.75mm maximum
• Thermal Resistance: 15°C/W
• Packaging Format: Tape & Reel (TR)
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity Level: 2A (4 Weeks)

Allowable Variation Parameter:

• CRI (Color Rendering Index): Substitutes with CRI 80 are acceptable alternatives to the primary part's CRI 90, provided all other parameters remain identical.

All three substitute part numbers meet these criteria and are classified as parametric equivalents within the LM282B series.

Parameter Comparison

Engineering Selection Recommendations

All substitute part numbers listed are classified as parametric equivalents and are interchangeable with the SPMWH1221FD7GBTMSB within the constraints of the provided specifications.

Selection Criteria Based on Product Status:

All four part numbers carry the "Not For New Designs" designation from Samsung Semiconductor. This status indicates that these components are in end-of-life phase and are no longer recommended for incorporation into new product designs. However, they remain available for existing production runs, maintenance applications, and field replacements where design continuity is required.

Compliance and Certification:

All substitute parts maintain identical RoHS compliance status and Moisture Sensitivity Level (MSL 2A, 4 Weeks) as the primary part number. This ensures that handling, storage, and assembly procedures remain consistent across all interchangeable options.

CRI Differentiation:

The primary part number SPMWH1221FD7GBTMSB and substitute SPMWH1221FD7GBT0SB both specify CRI 90, indicating superior color rendering capability. Substitutes SPMWH1221FD5GBT0SB and SPMWH1221FD5GBTMSB specify CRI 80. Selection between CRI 90 and CRI 80 variants depends on application-specific color rendering requirements. Both CRI levels are acceptable substitutes based on the provided parameter set.

Inventory Availability:

Current stock levels are: SPMWH1221FD7GBTMSB (44,840 pcs), SPMWH1221FD5GBT0SB (40,766 pcs), SPMWH1221FD5GBTMSB (39,747 pcs), and SPMWH1221FD7GBT0SB (40,355 pcs). All variants maintain substantial inventory in new original condition.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1221FD5GBT0SB be used as a direct replacement for SPMWH1221FD7GBTMSB?

A: Yes. SPMWH1221FD5GBT0SB is a parametric equivalent. The primary difference is CRI rating (80 versus 90). All electrical, thermal, optical, and mechanical parameters are identical. The substitution is valid provided the application does not require CRI 90 color rendering performance.

Q: What is the significance of the "FD5" versus "FD7" designation in the part number?

A: The "FD5" and "FD7" designations within the part number encode CRI specification. "FD7" indicates CRI 90, while "FD5" indicates CRI 80. All other parameters remain constant across these variants.

Q: Are the packaging formats identical across all substitute parts?

A: Yes. All four part numbers are supplied in Tape & Reel (TR) format with identical 2835 metric package dimensions (3.50mm × 2.80mm × 0.75mm maximum height). PCB footprints, pick-and-place machine compatibility, and reflow soldering profiles are identical.

Q: What does "Not For New Designs" mean for component selection?

A: This designation indicates the part has reached end-of-life status in Samsung's product roadmap. The component is no longer recommended for incorporation into new product designs. However, it remains available for existing production continuity, field replacements, and maintenance applications. All substitute parts carry the same status.

Q: Are there any thermal management differences between the substitute parts?

A: No. All substitute parts specify identical thermal resistance of 15°C/W. Thermal design calculations and heat dissipation strategies remain unchanged across all interchangeable options.

Q: What is the Moisture Sensitivity Level (MSL) requirement?

A: All parts specify MSL 2A with a 4-week floor life. This requires storage in controlled humidity environments (typically ≤30% RH) and limits the time between package opening and component assembly to 4 weeks under standard conditions. Handling procedures are identical across all substitute parts.

Q: Can these LEDs be operated at currents below 150mA?

A: The specifications provided define performance at 150mA test current. Operation at reduced currents is not addressed in the provided parameter set. Consult Samsung Semiconductor technical documentation for performance characteristics outside the specified test conditions.

Q: What is the difference between SPMWH1221FD5GBTMSB and SPMWH1221FD5GBT0SB?

A: Both parts specify identical electrical, optical, and mechanical parameters with CRI 80. The difference is encoded in the suffix: "MSIB" versus "0SB" designations. This typically indicates different manufacturing batches or packaging configurations. Functionally, they are equivalent for circuit design purposes.
