Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSMW-LWG0-NRSHE is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) of 3.22V
• Test current of 150mA with maximum current rating of 240mA
• Luminous flux output of 53lm at 25°C and 150mA test current
• Efficiency rating of 110 lm/W

Optical Compatibility:

• White color with warm 3000K color temperature
• Color Rendering Index of 80 (typical)
• Viewing angle of 120°

Mechanical Compatibility:

• Package type: 1113 (2835 Metric)
• Surface mount configuration
• Dimensions: 3.50mm x 2.80mm with maximum seated height of 0.90mm

Compliance & Qualification:

• Automotive grade component
• AEC-Q101 qualification
• ROHS3 compliance
• Thermal resistance of 47°C/W

The substitute part CSMW-LWG0-NR0HE shares the same base product number (CSMW-L), manufacturer (Broadcom Limited), package format (2835), and compliance certifications, establishing functional equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The CSMW-LWG0-NR0HE is the manufacturer-recommended substitute for the obsolete CSMW-LWG0-NRSHE. Both components are manufactured by Broadcom Limited and share identical base product designation, package format, and compliance certifications.

Active Product Status: The substitute part maintains active production status, ensuring long-term supply chain availability and support compared to the obsolete main part.

Compliance Alignment: Both parts meet ROHS3 compliance requirements and carry EAR99 export classification. The substitute maintains automotive-grade qualification standards through the shared CSMW-L base product family.

Moisture Sensitivity Consideration: The substitute part carries a Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), compared to the main part's MSL-1 (Unlimited). This difference requires adherence to moisture control protocols during storage and handling, with a maximum floor life of 168 hours after bag opening under specified humidity conditions.

Packaging Format: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments and differs from the main part's packaging specification. This format change does not affect electrical or optical performance but may require adjustment to component handling and placement equipment configurations.

Frequently Asked Questions (FAQ)

Q: Can the CSMW-LWG0-NR0HE directly replace the CSMW-LWG0-NRSHE in existing designs?

A: Yes. Both components share identical electrical characteristics (3.22V forward voltage, 150mA test current, 53lm luminous flux), optical properties (3000K warm white, 120° viewing angle), and mechanical form factor (2835 package, 3.50mm x 2.80mm). The substitute is the manufacturer-recommended equivalent.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The main part (MSL-1) has unlimited floor life after bag opening, while the substitute (MSL-3) has a maximum floor life of 168 hours under controlled humidity conditions (typically 30% relative humidity at 25°C). Production environments must implement moisture control procedures, including use of desiccant packs and controlled storage, to maintain component reliability.

Q: Does the Tape & Reel packaging format affect component performance?

A: No. Tape & Reel is a standard packaging format for surface-mount components and does not alter electrical, optical, or thermal performance. The format change affects only handling, storage, and automated placement procedures.

Q: Are both parts qualified for automotive applications?

A: Both components are part of the CSMW-L automotive-grade product family and carry AEC-Q101 qualification. The substitute maintains the same automotive reliability standards as the main part.

Q: What is the thermal management difference between these parts?

A: Both components specify a thermal resistance of 47°C/W. Thermal performance is equivalent, and junction temperature calculations use identical thermal resistance values for circuit design purposes.

Q: Can inventory of the obsolete part be mixed with the substitute in production?

A: Yes, from an electrical and optical standpoint. However, moisture sensitivity level differences require separate handling protocols. Components with different MSL ratings should be managed through separate inventory streams to prevent cross-contamination and ensure compliance with moisture control requirements specific to each part's rating.
