Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (LM281B Series – Not For New Designs):

The parts SPMWH1228FD5WAV0S3, SPMWH1228FD5WAVMS3, and SPMWH1228FD5WAVUS3 are direct parametric equivalents to the main part SPMWH3228FD5WAVMS3. All three maintain identical electrical and thermal characteristics, including forward voltage (3.1V), test current (150mA), flux output (60 lm), and package dimensions. These parts are suitable for direct substitution in existing designs where the LM281B series is acceptable. However, all four parts carry "Not For New Designs" status, indicating Samsung has discontinued active support for this product line.

Secondary Substitutes (LM281BZ+ Series – Active Status):

The parts SPMWH3228FD5WAV0SE, SPMWH3228FD5WAVKSE, and SPMWH3228FD5WAVMSE represent the active product line evolution. These LM281BZ+ series components maintain full compatibility with the main part across all critical parameters: color temperature (3000K), flux output (60 lm), CRI (80), viewing angle (120°), and package dimensions (2835 metric). The key difference is reduced forward voltage (3.0V typical versus 3.1V) and improved efficiency (133 lm/W versus 129 lm/W). These parts are designated as "Active" status and are recommended for new designs requiring warm white 3000K LED lighting in the 2835 package format.

Compliance and Certification:

All substitute parts maintain RoHS compliance and identical MSL rating (2A, 4 Weeks), ensuring compatibility with standard manufacturing and storage protocols. No additional qualification or testing is required for substitution within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q1: Can SPMWH1228FD5WAVUS3 be used as a direct replacement for SPMWH3228FD5WAVMS3?

A: Yes. SPMWH1228FD5WAVUS3 is a parametric equivalent. All electrical characteristics (3.1V forward voltage, 150mA test current, 60 lm flux), optical properties (3000K CCT, 80 CRI, 120° viewing angle), and mechanical specifications (2835 package, 3.50 × 2.80 mm, 0.75 mm height) are identical. The part number suffix differs only in packaging designation (US3 versus MS3), which does not affect component functionality.

Q2: What is the difference between the LM281B and LM281BZ+ series?

A: The LM281B series (SPMWH1228 base number) and LM281BZ+ series (SPMWH3228 base number) differ in forward voltage and efficiency. LM281B operates at 3.1V typical with 129 lm/W efficiency. LM281BZ+ operates at 3.0V typical with 133 lm/W efficiency. Both deliver identical 60 lm flux at 150mA test current and share the same 3000K color temperature, CRI, and package format. The LM281BZ+ series is the active product line.

Q3: Are the LM281BZ+ parts suitable for designs currently using LM281BZ?

A: Yes. The LM281BZ+ series maintains full backward compatibility with LM281BZ across all specified parameters. The reduced forward voltage (3.0V versus 3.1V) and improved efficiency (133 lm/W versus 129 lm/W) represent performance enhancements. Circuit designs operating at 150mA test current will function identically with either series.

Q4: What does "Not For New Designs" status mean?

A: "Not For New Designs" indicates that Samsung has transitioned the product to end-of-life status and is no longer recommending it for new applications. Existing inventory remains available, but long-term supply cannot be guaranteed. For new designs, the LM281BZ+ series (Active status) is the recommended alternative.

Q5: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts use the 1113 (2835 Metric) package with identical dimensions (3.50 × 2.80 mm) and maximum seated height (0.75 mm). Surface mount compatibility and PCB footprint requirements are identical across all listed parts.

Q6: Do the substitute parts require different thermal management?

A: No. All substitute parts maintain identical thermal resistance (25°C/W). Thermal design considerations, heat sink requirements, and thermal interface specifications remain unchanged.

Q7: What is the inventory status for each substitute part?

A: SPMWH1228FD5WAVUS3 has the highest availability (32929 Pcs), followed by SPMWH1228FD5WAVMS3 (3758 Pcs) and SPMWH1228FD5WAV0S3 (2401 Pcs). Among the active LM281BZ+ series, SPMWH3228FD5WAVKSE (940 Pcs) and SPMWH3228FD5WAV0SE (932 Pcs) have comparable stock levels, with SPMWH3228FD5WAVMSE at 728 Pcs.

Q8: Are moisture sensitivity and storage requirements identical?

A: Yes. All substitute parts carry MSL rating 2A (4 Weeks), indicating identical moisture sensitivity and storage protocol requirements. No additional desiccant or environmental controls are needed beyond standard handling procedures.
