Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD7WAVHS0 is determined by strict alignment across the following critical parameters:

Primary Substitution Criteria:

• Series family: LM561B or LM561B Plus (same base product number SPMWHT541)
• Color specification: White, Warm 3000K
• Electrical compatibility: Forward voltage 2.95V, test current 65mA
• Optical performance: CRI ≥ 90, viewing angle 120°
• Package configuration: 4-SMD surface mount, 5630 form factor
• Physical dimensions: 5.00mm × 3.00mm footprint
• Compliance: RoHS status and MSL rating

The SPMWHT541MP7WAVMS0 qualifies as a direct substitute based on these parameters. Both components share identical color temperature, forward voltage, test current, viewing angle, and physical footprint. The substitute maintains the same base product number (SPMWHT541) and operates within compatible electrical and thermal specifications.

Engineering Selection Recommendations

SPMWHT541MP7WAVMS0 as Primary Substitute:

The SPMWHT541MP7WAVMS0 is the qualified substitute for SPMWHT541MD7WAVHS0 applications. Selection is based on the following engineering factors:

Electrical Compatibility: Both components operate at identical forward voltage (2.95V) and test current (65mA), ensuring direct circuit compatibility without modification to current-limiting resistor networks or power supply specifications.

Optical Performance: Both maintain 3000K warm white color temperature and 90 CRI, preserving color rendering characteristics in lighting applications. The 120° viewing angle is identical, maintaining beam distribution patterns.

Physical Integration: Identical 5630 package footprint (5.00mm × 3.00mm) and compatible 4-SMD lead configuration enable direct PCB placement without layout redesign. The substitute's reduced height (0.80mm vs. 0.90mm) provides additional clearance margin.

Performance Enhancement: The SPMWHT541MP7WAVMS0 delivers improved specifications: 26 lumens vs. 24 lumens at test current, 136 lm/W vs. 125 lm/W efficiency, and 180mA maximum current vs. 150mA. These enhancements provide design margin without exceeding thermal or electrical limits.

Compliance Status: The substitute carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The main part's "Not For New Designs" status necessitates transition to the substitute for ongoing production.

Thermal Performance: Improved thermal resistance (15°C/W vs. 16°C/W) supports higher ambient temperature operation or increased current headroom.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAVMS0 replace SPMWHT541MD7WAVHS0 in existing designs without circuit modification?

A: Yes. Both components share identical forward voltage (2.95V), test current (65mA), and color temperature (3000K). No changes to current-limiting resistors, power supply specifications, or control circuitry are required. Direct substitution is electrically compatible.

Q: What is the difference between "Flat Lead Exposed Pad" and "Flat Leads" package designations?

A: Both refer to 4-SMD surface mount configurations with identical 5630 footprint and lead pitch. The package designation variation reflects minor manufacturing differences that do not affect PCB compatibility or electrical performance. Both are compatible with standard SMD assembly processes.

Q: Why does the substitute have higher maximum current (180mA vs. 150mA)?

A: The SPMWHT541MP7WAVMS0 represents an improved generation within the LM561B Plus series, featuring enhanced thermal management (15°C/W vs. 16°C/W) and die optimization. The higher maximum current rating reflects this improved thermal performance and does not require circuit changes when operating at the standard 65mA test current.

Q: Is the 0.10mm height difference (0.90mm vs. 0.80mm) significant for PCB assembly?

A: No. The 0.10mm reduction in maximum seated height is within standard SMD component tolerance and does not affect reflow soldering, pick-and-place accuracy, or clearance to adjacent components. This represents a design improvement providing additional headroom.

Q: What does "Not For New Designs" status mean for the main part?

A: This designation indicates Samsung has transitioned the SPMWHT541MD7WAVHS0 to end-of-life phase. The component remains available from existing inventory but will not receive design updates or extended production. The SPMWHT541MP7WAVMS0 (Active status) is the recommended path for new applications and ongoing production support.

Q: Are both components RoHS compliant?

A: Yes. The main part carries RoHS Compliant status. The substitute carries ROHS3 Compliant status, which represents a higher compliance standard. Both are suitable for applications requiring RoHS certification.

Q: Can I mix SPMWHT541MD7WAVHS0 and SPMWHT541MP7WAVMS0 in the same production batch?

A: Yes. Both components are electrically and optically identical at the 65mA test current specification. Mixing is acceptable for applications where component-level performance matching is not critical. For applications requiring strict luminous flux matching, components should be sourced from the same part number to ensure consistency within specified tolerance ranges.
