Key Parameters

Substitute Part Grouping Explanation

The SPMWHT541MP5WAVSS4 has two parametric equivalents within the LM561B Plus series. Substitution is based on the following critical parameters that remain constant across all three parts:

• Color and CCT: White, Warm 3000K
• Optical output: 32lm at 65mA test current (31lm ~ 33lm range)
• Electrical characteristics: 2.95V forward voltage, 65mA test current, 180mA maximum current
• Luminous efficiency: 167 lm/W at test current
• Color rendering: CRI 80
• Mechanical compatibility: 4-SMD flat leads, 5630 package, 5.00mm x 3.00mm x 0.80mm maximum height
• Viewing angle: 120°

The substitute parts SPMWHT541MP5WAV0S4 and SPMWHT541MP5WAVMS4 are electrically and optically identical to the main part. Differences exist only in thermal resistance specifications and compliance certifications, which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active production components from Samsung Semiconductor with full compliance certifications. Selection between SPMWHT541MP5WAVSS4, SPMWHT541MP5WAV0S4, and SPMWHT541MP5WAVMS4 is based on availability and compliance requirements:

SPMWHT541MP5WAVSS4 is the primary part with ROHS3 compliance and the lowest thermal resistance (14°C/W), suitable for applications with thermal management constraints.

SPMWHT541MP5WAV0S4 offers the highest inventory availability (85,670 pieces) with RoHS compliance and 16°C/W thermal resistance. Moisture sensitivity level is specified as 2A (4 Weeks).

SPMWHT541MP5WAVMS4 provides ROHS3 compliance matching the main part, with 50,200 pieces in stock and 16°C/W thermal resistance. Moisture sensitivity level is specified as 2A (4 Weeks).

All three parts are electrically and optically identical, with differences limited to thermal resistance and moisture sensitivity specifications. Selection should prioritize inventory availability and compliance certifications required by the end application.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. All three parts deliver identical electrical performance: 2.95V forward voltage, 65mA test current, 180mA maximum current, and 32 lumens at 25°C. They are direct functional equivalents.

Q: What is the difference in thermal resistance between the parts?

A: SPMWHT541MP5WAVSS4 has 14°C/W thermal resistance, while SPMWHT541MP5WAV0S4 and SPMWHT541MP5WAVMS4 both have 16°C/W. This 2°C/W difference is negligible in most standard applications but may be relevant in high-density thermal environments.

Q: Do all parts have the same moisture sensitivity?

A: SPMWHT541MP5WAVSS4 does not specify moisture sensitivity level. SPMWHT541MP5WAV0S4 and SPMWHT541MP5WAVMS4 both specify MSL 2A (4 Weeks), indicating they require controlled storage conditions.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All three parts use identical 4-SMD flat lead packages in 5630 format with matching dimensions (5.00mm x 3.00mm x 0.80mm maximum height) and are surface mount compatible with the same footprint.

Q: Which part should I select for RoHS3 compliance?

A: Both SPMWHT541MP5WAVSS4 and SPMWHT541MP5WAVMS4 are ROHS3 compliant. SPMWHT541MP5WAV0S4 is RoHS compliant but not specifically ROHS3 certified.

Q: Are there any optical differences between these parts?

A: No. All three parts are identical: White warm 3000K color, 32 lumens at 65mA, CRI 80, 120° viewing angle, and 167 lm/W efficiency.
