Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WAUSS0 is determined by the following critical parameters:

Color temperature (3500K warm white) and color point (White, Warm) must match exactly to maintain consistent lighting characteristics in the application.

Forward voltage (2.95V typical) and test current (65mA) establish the electrical operating point and must remain compatible with existing circuit designs.

Luminous flux output (30lm at 25°C, 65mA test current) and luminous efficacy (156 lm/W) define the light output performance envelope.

Color Rendering Index (CRI 90) specifies color accuracy requirements.

Viewing angle (120°) determines the light distribution pattern.

Thermal resistance (15°C/W) and maximum current rating (180mA) establish thermal and reliability parameters.

Package type (2212 / 5630 Metric) and physical dimensions (5.30mm x 3.00mm x 0.90mm max height) must accommodate existing PCB layouts and assembly processes.

RoHS3 compliance and REACH unaffected status ensure regulatory alignment.

The substitute part SPMWHT541MP7WAUSS0 meets these criteria within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAUSS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WAUSS0. Both components are Samsung Semiconductor products with identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current, 90 CRI, 120° viewing angle) and equivalent thermal characteristics (15°C/W).

The substitute maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The primary difference is product status: the main part is Last Time Buy while the substitute is Active, providing ongoing availability.

Luminous flux output differs slightly: the main part delivers 30lm (28lm ~ 32lm) at 156 lm/W, while the substitute delivers 28lm (25lm ~ 31lm) at 146 lm/W. Both values fall within acceptable performance ranges for warm white 3500K LED applications.

Physical dimensions show minor variations: the main part measures 5.30mm x 3.00mm x 0.90mm maximum height, while the substitute measures 5.00mm x 3.00mm x 0.80mm maximum height. These dimensional differences are within typical PCB layout tolerances for 5630 metric package footprints.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAUSS0 directly replace SPMWHT541MJ7WAUSS0 in existing designs?

A: Yes. Both components share identical electrical operating parameters (2.95V forward voltage, 65mA test current, 180mA maximum current) and thermal characteristics (15°C/W). The substitute is the manufacturer-recommended replacement and maintains the same color temperature (3500K), CRI (90), and viewing angle (120°).

Q: What is the difference in luminous output between these parts?

A: The main part delivers 30lm (28lm ~ 32lm) at 156 lm/W, while the substitute delivers 28lm (25lm ~ 31lm) at 146 lm/W. The substitute's minimum flux (25lm) is slightly lower than the main part's minimum (28lm), but both operate within acceptable ranges for warm white LED applications.

Q: Are there physical compatibility concerns?

A: Minor dimensional differences exist. The main part is 5.30mm x 3.00mm x 0.90mm maximum height; the substitute is 5.00mm x 3.00mm x 0.80mm maximum height. Both use 5630 metric package footprints. The substitute's smaller length (5.00mm vs 5.30mm) and lower profile (0.80mm vs 0.90mm) are compatible with standard 5630 PCB layouts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both SPMWHT541MJ7WAUSS0 and SPMWHT541MP7WAUSS0 are ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory status.

Q: Why is the main part designated Last Time Buy?

A: The SPMWHT541MJ7WAUSS0 (LM561B Plus series) is in end-of-life status. The SPMWHT541MP7WAUSS0 (LM561B series) is the active production equivalent, providing continued component availability for new designs and production continuity.

Q: Are the package designations interchangeable?

A: Both parts use 5630 metric package specifications. The main part is designated 2212 (5630 Metric), while the substitute is designated 4-SMD, Flat Leads (5630). These designations describe the same physical footprint with compatible lead configurations for surface mount assembly.
