Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MK7XAPSS0 is determined by the following critical parameters:

• Series Compatibility: LM561C series designation
• Color and CCT: White, Cool white at 6500K
• Electrical Performance: Forward voltage of 2.75V (typical), test current of 65mA, maximum current rating of 200mA
• Optical Characteristics: CRI of 90, 120° viewing angle
• Thermal Properties: 12°C/W thermal resistance
• Mounting and Compliance: Surface mount configuration, RoHS compliance status

The substitute part SPMWHT541ML7XAPSS0 maintains identical electrical specifications, color temperature, CRI, and thermal characteristics. Differences exist in package geometry (4-SMD Flat Leads vs. 2212), physical dimensions, and luminous flux output at rated current.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541ML7XAPSS0 is the manufacturer-recommended substitute for the SPMWHT541MK7XAPSS0. Both components share identical electrical characteristics, forward voltage, maximum current rating, color temperature, and CRI specification.

The substitute part carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the main part. Both components maintain equivalent RoHS compliance and export classification (EAR99).

Physical differences include package geometry and dimensional variations. The substitute features a 4-SMD Flat Leads configuration with reduced length (5.00mm vs. 5.30mm) and lower seated height (0.80mm vs. 0.90mm). Luminous flux output differs at rated current: 28 lumens for the substitute versus 32 lumens for the main part, resulting in lower efficiency (157 lm/W vs. 179 lm/W).

Component selection should account for PCB layout compatibility with the 4-SMD Flat Leads package format and the reduced luminous output specification of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAPSS0 be used as a direct replacement for SPMWHT541MK7XAPSS0?

A: Electrical and optical compatibility is maintained. Both parts operate at 2.75V forward voltage, 65mA test current, and deliver 90 CRI at 6500K color temperature. Package geometry and physical dimensions differ, requiring PCB layout verification. Luminous flux output is lower for the substitute part (28 lm vs. 32 lm at rated current).

Q: What are the key differences between these two parts?

A: The main differences are package configuration (2212 vs. 4-SMD Flat Leads), physical dimensions (5.30mm × 3.00mm vs. 5.00mm × 3.00mm length), seated height (0.90mm vs. 0.80mm), and luminous flux output (32 lm vs. 28 lm at 65mA). Electrical specifications, forward voltage, maximum current, CRI, and thermal resistance remain identical.

Q: Why does the substitute part have lower luminous flux?

A: The SPMWHT541ML7XAPSS0 delivers 28 lumens at 25°C and 65mA test current, compared to 32 lumens for the main part. This results in efficiency of 157 lm/W versus 179 lm/W. The difference reflects the specific optical and thermal design of the 4-SMD Flat Leads package variant.

Q: Are both parts RoHS compliant?

A: Yes. The main part is ROHS3 Compliant. The substitute part is RoHS Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the product status difference?

A: The SPMWHT541MK7XAPSS0 is designated Last Time Buy, indicating discontinued production. The SPMWHT541ML7XAPSS0 carries Active status, ensuring ongoing availability and supply continuity.

Q: Does the package change affect thermal performance?

A: Both parts maintain identical thermal resistance of 12°C/W. The 4-SMD Flat Leads package of the substitute part features a lower seated height (0.80mm vs. 0.90mm), which may affect thermal coupling to the PCB depending on layout design.
