Key Parameters

Substitute Part Grouping Explanation

The SPMWHT541ML7XAPMS0 qualifies as a direct substitute based on the following critical parameters:

• Series Match: Both parts belong to the LM561C series
• Color and CCT: Identical cool white 6500K specification
• Forward Voltage: Both operate at 2.75V typical
• Test Current: Both rated at 65mA
• Maximum Current: Both support 200mA maximum
• CRI Rating: Both maintain 90 CRI
• Viewing Angle: Both provide 120° viewing angle
• Thermal Resistance: Both rated at 12°C/W
• Compliance: Both meet RoHS requirements

The primary differences are package format (2212 vs. 5630 metric dimensions) and luminous flux output (32lm vs. 28lm at test current), with the substitute part representing an active product status alternative to the discontinued main part.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541ML7XAPMS0 is the designated manufacturer-recommended substitute for the discontinued SPMWHT541MK7XAPMS0. Selection of the substitute part is supported by:

• Active Product Status: The substitute maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts meet RoHS requirements; the substitute carries RoHS Compliant certification with MSL 2A (4 Weeks) moisture sensitivity rating
• Electrical Equivalence: Identical forward voltage, test current, maximum current, and CRI specifications ensure functional compatibility in existing circuit designs
• Thermal Performance: Matching thermal resistance (12°C/W) maintains thermal management characteristics
• Optical Specifications: Both parts deliver 120° viewing angle and 6500K cool white color temperature

The substitute part exhibits a 12.5% reduction in luminous flux (28lm vs. 32lm) and corresponding efficiency decrease (156 lm/W vs. 179 lm/W). Physical dimensions show minor variations in length (5.00mm vs. 5.30mm) and height (0.80mm vs. 0.90mm), with width remaining constant at 3.00mm. These differences require verification against specific application requirements and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAPMS0 be used as a direct replacement for SPMWHT541MK7XAPMS0?

A: The substitute part shares identical electrical specifications (2.75V, 65mA test current, 200mA maximum, 90 CRI, 120° viewing angle) and thermal characteristics (12°C/W). However, the 12.5% reduction in luminous flux and minor dimensional differences require application-specific validation before implementation.

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

A: The primary differences are: (1) luminous flux output (32lm vs. 28lm at 25°C, 65mA test current), (2) efficiency rating (179 lm/W vs. 156 lm/W), (3) package format designation (2212 vs. 4-SMD Flat Leads), (4) physical dimensions (length 5.30mm vs. 5.00mm, height 0.90mm vs. 0.80mm), and (5) product status (Last Time Buy vs. Active).

Q: Are there PCB layout considerations when switching to the substitute part?

A: Yes. The substitute part is 0.30mm shorter in length and 0.10mm lower in height. Verify that existing PCB footprints accommodate these dimensional variations and that solder joint clearances remain adequate for manufacturing processes.

Q: What is the moisture sensitivity level of the substitute part?

A: The SPMWHT541ML7XAPMS0 carries MSL 2A (4 Weeks) rating, indicating the component must be stored in controlled humidity conditions and used within four weeks of bag opening under standard moisture conditions.

Q: Do both parts meet the same regulatory standards?

A: Both parts are classified as EAR99 under export control and HTSUS 8541.41.0000 for tariff purposes. The main part is ROHS3 Compliant; the substitute is RoHS Compliant. Both meet applicable environmental and safety requirements for their respective product statuses.
