SPMWHT541MJ7WAPKS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT541MJ7WAPKS0 is an LED lighting component from Samsung Semiconductor's LM561B Plus series, featuring cool white 6500K color temperature. This part is designated as Last Time Buy, indicating discontinued production status. The component is a surface mount LED in 2212 (5630 Metric) package format with 120° viewing angle and 90 CRI rating.

Identifying equivalent and substitute parts is necessary due to the Last Time Buy status of the original component. Substitutes must maintain compatibility across electrical performance, thermal characteristics, and mechanical form factor to ensure proper operation in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WAPKS0 is determined by the following critical parameters:

• Series alignment: LM561B Plus
• Color and CCT matching: White, Cool 6500K
• Electrical compatibility: Forward voltage 2.95V, test current 65mA, maximum current 180mA
• Optical performance: CRI 90, 120° viewing angle
• Thermal characteristics: 15°C/W thermal resistance
• Mounting and package compatibility: Surface mount, 2212/5630 metric package family
• Compliance requirements: RoHS and REACH status

The substitute part SPMWHT541MP7WAPKS0 meets these criteria while maintaining functional equivalence within the LM561B Plus product line.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAPKS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WAPKS0. Both components share identical electrical characteristics, thermal properties, and optical specifications within the LM561B Plus series.

The substitute part maintains Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy designation of the original part. Both components meet RoHS compliance requirements, with the original part certified to ROHS3 and the substitute to RoHS standard.

Dimensional differences exist between the two parts: the substitute is slightly smaller in length (5.00mm vs 5.30mm) and lower in seated height (0.80mm vs 0.90mm). These dimensional variations remain within the 5630 metric package family and do not affect electrical or thermal performance.

Luminous flux output shows a minor variance: the original part delivers 30lm at 65mA test current, while the substitute delivers 27lm under identical conditions. This represents approximately 10% lower output, resulting in corresponding differences in lumens per watt efficiency (156 lm/W vs 141 lm/W). Both values fall within acceptable performance ranges for the LM561B Plus series.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAPKS0 be used as a direct replacement for SPMWHT541MJ7WAPKS0?

A: Yes. Both parts are from the same LM561B Plus series with identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), optical properties (6500K CCT, 90 CRI, 120° viewing angle), and thermal characteristics (15°C/W). The substitute is manufacturer-recommended and maintains compatibility in surface mount applications.

Q: What are the key differences between these parts?

A: The primary differences are product status and minor performance variations. The original part is Last Time Buy (discontinued), while the substitute is Active (current production). Luminous flux differs by approximately 10% (30lm vs 27lm at 65mA), and physical dimensions vary slightly within the 5630 package family. Thermal and electrical characteristics remain identical.

Q: Are there package compatibility concerns?

A: Both parts use 5630 metric package formats suitable for surface mount assembly. The original uses 2212 package designation while the substitute uses 4-SMD, Flat Leads designation. Dimensional differences are minor: length 5.30mm vs 5.00mm, height 0.90mm vs 0.80mm. Verify PCB footprint compatibility with your specific design requirements.

Q: Does the luminous flux difference affect circuit design?

A: The 10% flux reduction (30lm to 27lm) may require circuit adjustments if precise brightness levels are critical to application performance. Forward voltage and current characteristics remain unchanged, so driver circuits designed for the original part will function with the substitute. Evaluate application brightness requirements to determine if compensation is necessary.

Q: What compliance certifications apply to each part?

A: The original part is ROHS3 Compliant and REACH Unaffected. The substitute is RoHS Compliant. Both meet regulatory requirements for their respective designations. Verify compliance requirements for your specific application and regional market.
