Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for LED modules is determined by alignment across the following critical parameters:

Color and CCT Matching: Both the main part and substitute must operate at 5000K cool white to maintain consistent color output in end-use applications.

Configuration: Rectangle configuration is required to ensure mechanical fit within existing optical and thermal housings.

Electrical Compatibility: Forward voltage (Vf) and test current must fall within acceptable ranges to function with existing driver circuits. Luminous flux output should support the intended brightness requirements.

Compliance and Status: RoHS compliance is mandatory for regulatory adherence. Active product status is preferred to ensure ongoing availability and supply chain support.

Optical Properties: CRI values above 70 are acceptable for general lighting applications; lens type (flat vs. domed) affects light distribution characteristics.

The substitute part MP26T1-C19-5070-W-2-00 from New Energy meets these core substitution criteria through matching color temperature, configuration, compliance status, and electrical operating range.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The SL-IGR7E970BWW carries "Not For New Designs" status, indicating limited future availability. The substitute MP26T1-C19-5070-W-2-00 holds "Active" status, ensuring ongoing supply and manufacturer support.

Compliance Alignment

Both parts are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory and trade compliance equivalence.

Electrical Operating Range

The substitute operates at 46.1V forward voltage versus 52.2V for the main part, representing a 6.1V reduction. Test current decreases from 1.35A to 1.05A. These differences require driver circuit verification to confirm compatibility with existing power supply designs.

Luminous Flux and Efficiency Trade-off

The main part delivers 9700 lm at 138 lm/W. The substitute provides 7512 lm at 155 lm/W. The substitute achieves higher efficiency but lower absolute output. Application brightness requirements must be evaluated against this 22.6% reduction in luminous flux.

Mechanical Fit Constraints

Dimensional differences are significant: the substitute is smaller in length and width (203.20 × 111.00 mm vs. 245.00 × 186.00 mm) but taller (93.98 mm vs. 45.60 mm). Optical housing and thermal management designs must accommodate these changes.

Optical Characteristics

The main part features a flat lens with CRI 75. The substitute uses a domed lens with CRI 70. Domed optics produce wider light distribution; flat optics provide more directed output. Application-specific lighting patterns must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can MP26T1-C19-5070-W-2-00 directly replace SL-IGR7E970BWW without modifications?

A: Direct mechanical and electrical replacement is not possible without design modifications. The substitute has different dimensions (smaller footprint, greater height), lower forward voltage (46.1V vs. 52.2V), and different lens geometry (domed vs. flat). Driver circuits and optical housings require redesign.

Q: What is the impact of the 22.6% reduction in luminous flux?

A: The substitute delivers 7512 lm versus 9700 lm. Applications requiring the full 9700 lm output cannot use this substitute without additional modules or alternative designs. Brightness-critical applications must be reassessed.

Q: Are both parts RoHS compliant?

A: Yes. Both SL-IGR7E970BWW and MP26T1-C19-5070-W-2-00 are RoHS Compliant and share identical trade classification codes (ECCN: EAR99; HTSUS: 8541.41.0000).

Q: Why does the substitute have higher lumens/watt efficiency but lower total output?

A: Efficiency (lm/W) is a ratio of light output to power input. The substitute achieves 155 lm/W versus 138 lm/W through optimized LED die selection and thermal design. However, it operates at lower absolute current (1.05A vs. 1.35A), resulting in lower total luminous flux despite higher efficiency.

Q: What is the significance of the lens type difference?

A: The main part uses a flat lens for directed, concentrated light output. The substitute uses a domed lens for wider angular distribution. Optical system design, reflector geometry, and beam angle specifications must be re-evaluated for the substitute.

Q: Is the substitute suitable for new product designs?

A: Yes. The substitute holds "Active" product status, indicating manufacturer commitment to ongoing production and support. The main part's "Not For New Designs" status makes the substitute the preferred choice for new development.

Q: What driver circuit changes are required?

A: The substitute operates at 46.1V forward voltage (6.1V lower) and 1.05A test current (0.3A lower) compared to the main part. Power supply output voltage and current limiting must be adjusted accordingly. Thermal management may also require modification due to different power dissipation characteristics.
