Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WAVMS0 is determined by the following critical parameters:

• Series alignment: LM561B Plus
• Color specification: White, Warm 3000K
• Electrical compatibility: Forward voltage 2.95V, test current 65mA, maximum current 180mA
• Optical performance: CRI 90, 120° viewing angle
• Compliance: ROHS3 Compliant, REACH Unaffected
• Mounting: Surface mount technology

The substitute part SPMWHT541MP7WAVMS0 meets all these criteria while differing in package configuration and physical dimensions, representing a direct functional equivalent with alternative form factor.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAVMS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WAVMS0. Both components maintain identical electrical specifications, color temperature, CRI rating, and viewing angle. The substitute part carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.

Key differences are limited to package configuration and physical dimensions. The substitute features a 4-SMD flat lead package with slightly reduced length (5.00mm vs 5.30mm) and height (0.80mm vs 0.90mm). Luminous flux output shows a 3lm reduction at 25°C test conditions, resulting in lower lumens/watt efficiency (136 lm/W vs 151 lm/W). Both parts maintain identical thermal resistance and compliance certifications.

Selection between these parts depends on PCB layout constraints and thermal management requirements. The substitute's reduced height may provide advantages in space-constrained applications, while the original part's higher efficiency may be preferred in power-sensitive designs where the 15 lm/W difference is material to system performance.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAVMS0 directly replace SPMWHT541MJ7WAVMS0 in existing designs?

A: Electrical and optical compatibility is confirmed. PCB layout modifications may be required due to package configuration differences. The substitute's reduced physical dimensions (length and height) typically allow drop-in replacement in most applications, though footprint verification is necessary.

Q: What is the significance of the flux difference between these parts?

A: The SPMWHT541MJ7WAVMS0 delivers 29lm at 25°C test conditions, while the substitute delivers 26lm. This 3lm difference represents approximately 10% lower light output. Applications with strict luminous intensity requirements should evaluate whether this variance affects system performance.

Q: Are both parts suitable for high-temperature operation?

A: Both parts share identical thermal resistance of 15°C/W. Thermal performance is equivalent. Operating temperature limits and derating curves should be consulted from the manufacturer datasheet for specific application conditions.

Q: What packaging format differences exist?

A: The original part uses 2212 (5630 Metric) package format. The substitute uses 4-SMD flat lead configuration in 5630 metric dimensions. Both are surface mount components with compatible solder reflow processes.

Q: Are compliance certifications identical?

A: Both parts are ROHS3 Compliant and REACH Unaffected. Regulatory compliance is equivalent for both components.
