SPMWH1221FD7GBT0SA LED Equivalent & Substitute Parts

Part Overview

The SPMWH1221FD7GBT0SA is a Samsung Semiconductor LM282B series surface mount LED designed for neutral white lighting applications at 4000K color temperature. This component operates at 6.3V forward voltage with a 150mA test current, delivering 110 lumens at 25°C in a compact 2835 metric package (1113 case size).

The product carries a "Not For New Designs" status, indicating that Samsung has discontinued active development for this component line. This status necessitates identification of equivalent substitute parts to maintain design continuity, ensure supply chain reliability, and support existing production requirements for applications currently utilizing this LED.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1221FD7GBT0SA is determined by strict equivalence across 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
• Flux @ 25°C: 110 lm (105–115 lm range)
• Lumens/Watt: 116 lm/W
• Viewing Angle: 120°
• Thermal Resistance: 15°C/W
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Allowable Variation Parameter:

• Color Rendering Index (CRI): 80 or 90 (both acceptable for neutral white 4000K applications)

All three substitute parts maintain identical electrical, thermal, and mechanical specifications. The only permitted variation is CRI, where both CRI 80 and CRI 90 versions are functionally interchangeable within the LM282B product line for neutral white 4000K lighting applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are direct parametric equivalents to the SPMWH1221FD7GBT0SA and are suitable for direct replacement in existing applications. Selection among the substitute options should be based on the following criteria:

CRI Requirement:

• If Color Rendering Index 90 is required: Select SPMWH1221FD7GBTMSA (49,017 pcs available) or maintain SPMWH1221FD7GBT0SA (44,233 pcs available)
• If Color Rendering Index 80 is acceptable: Select SPMWH1221FD5GBT0SA (16,508 pcs available) or SPMWH1221FD5GBTMSA (34,900 pcs available)

Inventory Availability:

• SPMWH1221FD7GBTMSA: 49,017 pcs (highest stock)
• SPMWH1221FD5GBTMSA: 34,900 pcs
• SPMWH1221FD7GBT0SA: 44,233 pcs (main part)
• SPMWH1221FD5GBT0SA: 16,508 pcs (lowest stock)

Compliance Status: All parts maintain RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring compatibility with standard surface mount assembly processes and storage requirements.

Product Status Consideration: All parts carry "Not For New Designs" status. For applications requiring long-term supply assurance, evaluate alternative LED product lines with active design status from Samsung Semiconductor or other manufacturers offering equivalent LM282B-class neutral white 4000K LEDs in 2835 packages.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1221FD5GBT0SA be used as a direct replacement for SPMWH1221FD7GBT0SA?

A: Yes. Both parts are parametrically equivalent across all electrical, thermal, and mechanical specifications. The only difference is Color Rendering Index (CRI 80 vs. CRI 90). If the application does not specify CRI 90 as a requirement, SPMWH1221FD5GBT0SA is a direct substitute.

Q: What is the difference between the "FD5" and "FD7" designations in the part numbers?

A: Based on the provided data, the FD5 and FD7 designations correlate to CRI values: FD5 indicates CRI 80, and FD7 indicates CRI 90. All other parameters remain identical.

Q: Are the "GBT0SA" and "GBTMSA" packaging variants interchangeable?

A: Yes. Both variants use identical Tape & Reel (TR) packaging and are suitable for automated surface mount assembly. The designations reflect internal Samsung product classification but do not affect electrical performance, thermal characteristics, or mechanical compatibility.

Q: What is the impact of CRI 80 versus CRI 90 on lighting performance?

A: Color Rendering Index measures the accuracy of color reproduction under the LED light source. CRI 90 provides superior color fidelity compared to CRI 80. Selection depends on application requirements: general illumination applications typically accept CRI 80, while applications requiring accurate color representation (retail, display, photography) may require CRI 90.

Q: Can these LEDs be used in new product designs?

A: All parts carry "Not For New Designs" status. Samsung has discontinued active development for the LM282B series. New designs should evaluate alternative LED product lines with active design status to ensure long-term supply availability and access to design support.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four parts (main and three substitutes) are RoHS compliant and carry identical MSL ratings (2A, 4 Weeks), ensuring compatibility with standard lead-free surface mount assembly and storage protocols.

Q: What is the thermal resistance specification, and why is it important?

A: Thermal resistance of 15°C/W is identical across all parts. This specification indicates the temperature rise per watt of power dissipation. At 150mA and 6.3V (0.945W), the junction temperature rise above ambient is approximately 14.2°C. This parameter is critical for thermal design and ensures consistent performance across all substitute options.

Q: Are there inventory differences that should influence part selection?

A: Yes. SPMWH1221FD7GBTMSA has the highest inventory (49,017 pcs), followed by SPMWH1221FD7GBT0SA (44,233 pcs). If supply continuity is a concern, prioritize parts with higher available stock. However, all parts are currently in stock as new original components.
