Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WARMS0 is determined by strict alignment of the following critical parameters:

• Color Temperature (CCT): Must remain 5000K (cool white) to maintain color consistency in end-application lighting systems
• Forward Voltage (Vf): Must be 2.95V typical to ensure compatibility with existing circuit designs and current-limiting resistor calculations
• Test Current: Must be 65mA to maintain luminous output specifications and thermal performance
• Color Rendering Index (CRI): Must be 90 to preserve color fidelity requirements
• Viewing Angle: Must be 120° to match optical distribution characteristics
• Maximum Current Rating: Must be 180mA or higher to support design margin requirements
• Mounting Type: Must be Surface Mount (SMD) for PCB assembly compatibility
• Thermal Resistance: Must be 15°C/W or lower to meet thermal management specifications
• Regulatory Compliance: Must maintain ROHS3 compliance status

The substitute part SPMWHT541MP7WARMS0 meets all these criteria while offering improved supply availability and active product status.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WARMS0 is the qualified substitute for SPMWHT541MJ7WARMS0 based on the following engineering criteria:

Product Status Alignment: The main part carries Last Time Buy designation, indicating end-of-life status. The substitute maintains Active product status, ensuring long-term supply chain viability and continued manufacturer support.

Electrical Compatibility: Both components operate at identical forward voltage (2.95V), test current (65mA), and maximum current rating (180mA). Circuit designs require no modification for voltage or current parameters.

Optical Specifications: Both parts deliver 5000K color temperature with 90 CRI and 120° viewing angle. The luminous flux variance (32 lm vs. 28 lm at 65mA test current) falls within acceptable tolerance ranges for lighting applications where color temperature and rendering index are primary requirements.

Thermal Performance: Identical thermal resistance (15°C/W) ensures equivalent thermal management characteristics in PCB assembly designs.

Regulatory Compliance: Both components maintain ROHS3 compliance status, satisfying environmental and hazardous substance restrictions.

Physical Compatibility: The substitute's 4-SMD flat lead package (5630) is mechanically compatible with 2212 footprints. Dimensional differences (5.00mm vs. 5.30mm length; 0.80mm vs. 0.90mm height) remain within standard PCB assembly tolerances.

Supply Availability: The substitute offers significantly higher inventory availability (25904 Pcs vs. 1034 Pcs), reducing procurement risk and lead time exposure.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WARMS0 be used as a direct replacement without PCB redesign?

A: Yes. The substitute maintains identical electrical parameters (Vf, test current, maximum current) and thermal resistance. Physical dimensions are compatible with standard 2212 footprints. No circuit modifications are required.

Q: What is the impact of the luminous flux difference (32 lm vs. 28 lm)?

A: The 4 lumen difference represents approximately 12.5% variance at the 65mA test current. Both values fall within acceptable ranges for cool white 5000K lighting applications. Applications requiring specific lumen output should verify the substitute's 28 lm specification against system-level brightness requirements.

Q: Are the package designations "2212" and "4-SMD, Flat Leads" interchangeable?

A: Both designations refer to the 5630 metric package format. The 4-SMD flat lead configuration is the standard surface mount implementation for this package size. PCB footprints designed for 2212 (5630) accommodate the substitute without modification.

Q: Does the substitute maintain the same color rendering quality?

A: Yes. Both components specify 90 CRI at 5000K color temperature. Color fidelity and rendering characteristics remain identical.

Q: Why is the substitute recommended despite lower lumens/watt efficiency?

A: The substitute delivers 146 lm/W versus 167 lm/W at the 65mA test current. This 12.7% efficiency difference is offset by superior supply availability, active product status, and identical electrical and thermal specifications. For applications where absolute efficiency is critical, verify the substitute's performance against system power budget requirements.

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

A: The substitute specifies MSL 2A (4 Weeks), indicating standard moisture sensitivity for surface mount LED components. Standard moisture control procedures during storage and assembly apply.
