SPMWHT541MJ7WAPMS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT541MJ7WAPMS0 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 configuration with 120° viewing angle and high luminous efficacy of 156 lm/W at rated current.

Due to Last Time Buy status, identifying equivalent substitute parts is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WAPMS0 is determined by the following critical parameters:

• Color and CCT Match: White, Cool 6500K specification must be maintained
• Electrical Compatibility: Forward voltage (2.95V typical), test current (65mA), and maximum current (180mA) must align
• Optical Performance: CRI of 90 and 120° viewing angle must be preserved
• Series Compatibility: LM561B Plus series designation
• Thermal Characteristics: Thermal resistance of 15°C/W
• Compliance Requirements: RoHS and REACH status

The substitute part SPMWHT541MP7WAPMS0 meets these core substitution criteria while differing in package configuration and luminous flux specification.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAPMS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WAPMS0. Both components maintain identical electrical characteristics (2.95V forward voltage, 65mA test current, 180mA maximum current) and optical properties (6500K CCT, 90 CRI, 120° viewing angle).

The substitute part carries Active product status, ensuring continued availability and supply chain support. Both parts comply with RoHS regulations and share identical thermal resistance specifications (15°C/W).

Primary differences exist in package configuration and luminous flux output. The substitute features a 4-SMD flat lead package with slightly reduced dimensions (5.00mm x 3.00mm versus 5.30mm x 3.00mm) and lower seated height (0.80mm versus 0.90mm). Luminous flux at 25°C is specified as 27lm (24lm ~ 30lm) compared to 30lm (28lm ~ 32lm), resulting in luminous efficacy of 141 lm/W versus 156 lm/W.

Selection between these parts depends on PCB layout constraints and luminous output requirements. The substitute's compact dimensions and lower profile may provide design advantages in space-constrained applications, while the main part's higher luminous efficacy may be preferred for brightness-critical designs.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAPMS0 be used as a direct replacement for SPMWHT541MJ7WAPMS0?

A: Yes, with consideration for package differences. Both parts share identical electrical specifications (2.95V Vf, 65mA test current) and optical properties (6500K, 90 CRI, 120° viewing angle). However, the substitute features different package geometry and lead configuration (4-SMD flat leads versus 2212 package), requiring PCB layout verification.

Q: What is the luminous flux difference between these parts?

A: The main part specifies 30lm (28lm ~ 32lm) at 25°C, while the substitute specifies 27lm (24lm ~ 30lm). This results in luminous efficacy of 156 lm/W versus 141 lm/W respectively. The overlap in tolerance ranges (28lm ~ 30lm) indicates partial compatibility for brightness-sensitive applications.

Q: Are there compliance differences between these parts?

A: The main part carries ROHS3 Compliant status, while the substitute carries RoHS Compliant status. Both meet regulatory requirements. The substitute additionally specifies Moisture Sensitivity Level (MSL) of 2A (4 Weeks), indicating standard moisture handling requirements for surface mount components.

Q: What are the physical dimension differences?

A: The main part measures 5.30mm L x 3.00mm W with 0.90mm maximum seated height. The substitute measures 5.00mm L x 3.00mm W with 0.80mm maximum seated height. These differences require verification against PCB footprint and clearance requirements.

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

A: Last Time Buy status indicates Samsung Semiconductor has discontinued production of the SPMWHT541MJ7WAPMS0. The SPMWHT541MP7WAPMS0 remains in Active production status, making it the recommended path for ongoing procurement and design continuity.
