All substitute parts maintain 100% parameter alignment with the main part across these categories, enabling direct functional replacement in existing designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SPMWH1221FD5GBTKSA, SPMWH1221FD5GBT0SA, and SPMWH1221FD5GBTMSA—are classified as "Not For New Designs" by Samsung Semiconductor, Inc., indicating end-of-life status across the entire LM282B series. Selection among these equivalents should be based on supply chain availability and inventory levels rather than technical differentiation, as all parts maintain identical electrical, optical, and mechanical specifications.

Compliance Considerations: All substitute parts carry RoHS Compliant certification and identical Moisture Sensitivity Level (MSL) ratings of 2A (4 Weeks), ensuring equivalent environmental and regulatory compliance for applications requiring these certifications.

Inventory Availability:

• SPMWH1221FD5GBTKSA: 1,075 pcs
• SPMWH1221FD5GBT0SA: 16,508 pcs
• SPMWH1221FD5GBTMSA: 34,900 pcs

For applications requiring immediate or high-volume procurement, SPMWH1221FD5GBTMSA offers the highest available inventory. All parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1221FD5GBT0SA and SPMWH1221FD5GBTMSA be used interchangeably with SPMWH1221FD5GBTKSA?

A: Yes. All three parts are parametric equivalents with identical electrical specifications (6.3V forward voltage, 150mA test current), optical output (110 lm at 4000K), mechanical dimensions (3.50mm × 2.80mm, 0.75mm height), and package type (1113 / 2835 metric). Direct substitution is supported without circuit or PCB layout modifications.

Q: What does "Not For New Designs" status mean for these parts?

A: This designation indicates that Samsung Semiconductor, Inc. has discontinued active development and long-term support for the LM282B series. These parts remain available for existing production support and maintenance applications but should not be selected for new product development. Substitute parts within this series maintain identical specifications but share the same end-of-life status.

Q: Are there any differences in the part numbers that affect compatibility?

A: The part numbers differ only in their suffix codes (GBTKSA, GBT0SA, GBTMSA), which represent internal Samsung manufacturing or packaging variants. These suffixes do not affect electrical performance, optical characteristics, or mechanical compatibility. All parts are functionally equivalent for circuit design purposes.

Q: What is the significance of the 2835 metric package designation?

A: The 2835 metric package (case code 1113) is a standardized surface-mount LED footprint measuring 3.50mm × 2.80mm with a maximum seated height of 0.75mm. All substitute parts conform to this specification, ensuring compatibility with existing PCB designs and automated pick-and-place assembly equipment.

Q: How should moisture sensitivity (MSL 2A) be managed during storage and assembly?

A: MSL 2A (4 Weeks) indicates that these components can be stored in a dry environment for up to 4 weeks after the moisture barrier bag is opened. After this period, components must be baked according to IPC-A-610 standards before reflow soldering. All substitute parts share this identical MSL rating.

Q: What thermal considerations apply when selecting between these substitute parts?

A: All three parts have identical thermal resistance of 15°C/W. Thermal performance in the application is determined by PCB thermal design, solder pad area, and thermal vias rather than part selection. No thermal differentiation exists between the substitute options.

Q: Are these parts suitable for high-volume automated assembly?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, the standard format for automated surface-mount assembly. The identical 2835 metric package ensures compatibility with standard pick-and-place equipment and reflow soldering processes.
