Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAVMSC is determined by the following critical parameters:

Primary Matching Criteria:

• Series family: LM561B or LM561B Plus
• Color specification: White, Warm
• Correlated Color Temperature (CCT): 3000K
• Forward voltage (Vf): 2.95V nominal
• Test current: 65mA
• Viewing angle: 120°
• Package type: 4-SMD surface mount, 5630 form factor
• Physical dimensions: 5.00mm L x 3.00mm W
• CRI: 80 or higher

Secondary Compatibility Parameters:

• Current rating (maximum): Equal to or greater than 150mA
• Thermal resistance: 16°C/W
• Moisture sensitivity level: 2A classification
• RoHS compliance status

The SPMWHT541MP5WAVMS4 qualifies as a direct substitute based on matching all primary criteria and maintaining compatibility across secondary parameters. The LM561B Plus variant represents an active product line evolution with improved performance characteristics while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

For Existing Designs Using SPMWHT541MD5WAVMSC:

The SPMWHT541MP5WAVMS4 is the direct substitute for ongoing production and maintenance. This substitution is supported by:

• Identical electrical specifications (Vf, test current, CRI, viewing angle)
• Matching physical footprint and thermal characteristics
• Enhanced efficiency (167 lm/W vs. 162 lm/W) with no design impact
• Improved product status (Active vs. Not For New Designs)
• Higher RoHS compliance level (ROHS3)
• Increased maximum current rating (180mA vs. 150mA) providing design margin
• Reduced seated height (0.80mm vs. 0.90mm) improving PCB clearance

For New Design Initiatives:

The SPMWHT541MP5WAVMS4 (LM561B Plus) is the recommended selection. The original SPMWHT541MD5WAVMSC should not be used in new designs due to its end-of-life classification.

Compliance Considerations:

Both parts maintain RoHS compliance and identical moisture sensitivity levels, ensuring no supply chain or environmental regulatory impact from substitution.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541MD5WAVMSC in existing PCB assemblies?

A: Yes. The substitute part maintains identical forward voltage (2.95V), test current (65mA), color temperature (3000K), viewing angle (120°), and physical dimensions (5.00 x 3.00mm). The 4-SMD surface mount package is compatible with existing reflow processes and PCB layouts.

Q: What are the differences between the main part and substitute?

A: The SPMWHT541MP5WAVMS4 offers improved luminous efficiency (167 lm/W vs. 162 lm/W), higher maximum current rating (180mA vs. 150mA), reduced seated height (0.80mm vs. 0.90mm), and active product status. Electrical performance at rated test current (65mA) remains equivalent.

Q: Are there any package or lead configuration differences?

A: The main part features a flat lead with exposed pad, while the substitute uses flat leads without exposed pad specification. Both are 4-SMD, 5630 form factor packages with identical external dimensions and thermal resistance (16°C/W).

Q: Does substitution require PCB design changes?

A: No. The substitute part's reduced seated height (0.80mm vs. 0.90mm) provides additional PCB clearance but does not necessitate design modifications. Existing footprints and assembly parameters remain valid.

Q: What is the inventory status for each part?

A: SPMWHT541MD5WAVMSC has 2,600 pieces in stock (end-of-life inventory). SPMWHT541MP5WAVMS4 has 50,200 pieces in stock (active product). For long-term supply security, the substitute is the preferred selection.

Q: Are both parts RoHS compliant?

A: Yes. SPMWHT541MD5WAVMSC is RoHS Compliant. SPMWHT541MP5WAVMS4 is ROHS3 Compliant, representing a higher compliance standard. Both parts meet environmental regulatory requirements.

Q: Can the substitute handle higher current applications?

A: The substitute's maximum current rating is 180mA compared to 150mA for the main part. However, both parts are specified for 65mA test current. Applications requiring higher current should be evaluated against the substitute's 180mA maximum rating, which provides additional design margin.
