Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of electrical and mechanical parameters. The SPMWHT541ML5XAPNS0 accepts substitutes in two categories:

Parametric Equivalents (Identical Specifications): Parts SPMWHT541ML5XAP0S0, SPMWHT541ML5XAP0S6, SPMWHT541ML5XAPKS6, and SPMWHT541ML5XAPMS6 are direct parametric equivalents. All share identical electrical characteristics: 2.75V forward voltage, 65mA test current, 36 lumens output, 201 lm/W efficiency, 80 CRI, and 120° viewing angle. Mechanical specifications are identical: 5630 package, 4-SMD flat leads, 5.00mm x 3.00mm dimensions, 0.80mm maximum seated height, and 12°C/W thermal resistance. All are RoHS Compliant with 2A MSL rating. The primary difference is product status: these equivalents are classified as "Active," making them suitable for new designs where the original part is not.

Similar Substitute (Modified Specifications): Part SPMWHT541MP5WAPKS4 is a similar substitute from the LM561B Plus series. This part maintains compatibility in color (White, Cool 6500K), package type (5630, 4-SMD flat leads), mechanical dimensions (5.00mm x 3.00mm, 0.80mm height), and mounting method (Surface Mount, Tape & Reel). However, it introduces electrical differences: forward voltage increases to 2.95V, maximum current decreases to 180mA, luminous flux reduces to 33 lumens, and efficiency decreases to 167 lm/W. Thermal resistance increases to 15°C/W. This part carries ROHS3 Compliant status and is classified as "Active."

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents): Parts SPMWHT541ML5XAP0S0, SPMWHT541ML5XAP0S6, SPMWHT541ML5XAPKS6, and SPMWHT541ML5XAPMS6 are recommended for applications requiring identical electrical and thermal performance. These parts maintain 2.75V forward voltage, 201 lm/W efficiency, and 12°C/W thermal resistance. All four are classified as "Active" and RoHS Compliant, making them suitable for new design implementations. Selection among these four equivalents may be based on inventory availability and packaging lot requirements.

For Similar Substitution (Modified Performance): Part SPMWHT541MP5WAPKS4 (LM561B Plus series) is suitable only when the application can tolerate increased forward voltage (2.95V), reduced luminous flux (33 lumens), lower efficiency (167 lm/W), and higher thermal resistance (15°C/W). This part is classified as "Active" with ROHS3 Compliant status. The higher inventory level (48,482 pcs) indicates greater availability. Use this substitute only when circuit design accommodates the 0.20V voltage increase and reduced light output.

Compliance Considerations: All substitute parts maintain MSL 2A (4 Weeks) moisture sensitivity rating and surface mount compatibility with 5630 package specifications. RoHS and ROHS3 compliance certifications are maintained across all options.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAP0S0, SPMWHT541ML5XAP0S6, SPMWHT541ML5XAPKS6, and SPMWHT541ML5XAPMS6 be used interchangeably with SPMWHT541ML5XAPNS0?

A: Yes. These four parts are parametric equivalents with identical electrical specifications (2.75V, 65mA, 36 lumens, 201 lm/W), mechanical dimensions (5.00mm x 3.00mm, 0.80mm height), and thermal characteristics (12°C/W). The primary difference is product status: the equivalents are "Active" while the original is "Not For New Designs." No circuit modifications are required.

Q: What are the key differences between the LM561C and LM561B Plus series?

A: The LM561B Plus (SPMWHT541MP5WAPKS4) introduces three measurable differences: forward voltage increases from 2.75V to 2.95V, luminous flux decreases from 36 lumens to 33 lumens, and thermal resistance increases from 12°C/W to 15°C/W. Maximum current also decreases from 200mA to 180mA. These changes result in lower efficiency (167 lm/W versus 201 lm/W).

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use identical 5630 package specifications with 4-SMD flat leads, 5.00mm x 3.00mm dimensions, and 0.80mm maximum seated height. PCB footprints and reflow profiles remain unchanged.

Q: What is the impact of using SPMWHT541MP5WAPKS4 in a circuit designed for SPMWHT541ML5XAPNS0?

A: The 0.20V forward voltage increase (2.75V to 2.95V) requires circuit verification to ensure adequate supply voltage margin. The 3-lumen reduction in luminous flux and 34 lm/W efficiency decrease will result in lower light output. The 3°C/W increase in thermal resistance may affect thermal management in high-density applications. Use only if the application design accommodates these parameter changes.

Q: Which substitute part offers the best inventory availability?

A: SPMWHT541MP5WAPKS4 (LM561B Plus) has the highest inventory at 48,482 pieces. Among parametric equivalents, SPMWHT541ML5XAPKS6 offers 5,200 pieces. The original part SPMWHT541ML5XAPNS0 has 1,033 pieces remaining.

Q: Do all parts maintain the same moisture sensitivity and RoHS compliance?

A: All parts carry MSL 2A (4 Weeks) rating. RoHS compliance is maintained: the LM561C variants are RoHS Compliant, while SPMWHT541MP5WAPKS4 is ROHS3 Compliant. Both certifications are acceptable for equivalent substitution.
