Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SPMWHT541MP5WAVMS4

SPMWHT541MP5WAVMS4 is the preferred substitute for SPMWHT541MP5WAVRS4. This part maintains full electrical and mechanical equivalence with superior product status classification (Active). It carries ROHS3 Compliant certification, providing enhanced regulatory compliance. Inventory availability of 50,200 units ensures supply continuity for production requirements.

Secondary Recommendation: SPMWHT541MP5WAV0S4

SPMWHT541MP5WAV0S4 offers the highest inventory availability at 85,670 units, supporting large-volume production needs. Product status is Active with RoHS Compliant certification. Thermal resistance specification of 16°C/W remains within acceptable tolerance range.

Alternative Options: SPMWHT541MP5WAVNS4 and SPMWHT541MP5WAVKS4

Both parts maintain Active product status and full parametric equivalence. SPMWHT541MP5WAVNS4 carries RoHS Compliant certification with 1,011 units available. SPMWHT541MP5WAVKS4 provides 795 units with RoHS Compliant status and 15°C/W thermal resistance matching the original part specification.

Thermal Performance Consideration: SPMWHT541MP5WAVSS4

SPMWHT541MP5WAVSS4 offers the lowest thermal resistance at 14°C/W with ROHS3 Compliant and REACH Unaffected certifications. This variant is suitable for applications requiring enhanced thermal performance. Inventory availability is 877 units.

All substitute parts are direct functional replacements requiring no circuit design modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541MP5WAVRS4?

A: Yes. SPMWHT541MP5WAVMS4 is a direct parametric equivalent. All electrical specifications (forward voltage, test current, luminous flux, CRI, viewing angle) are identical. Mechanical compatibility is confirmed through matching package type (4-SMD, Flat Leads, 5630), dimensions (5.00mm x 3.00mm x 0.80mm), and mounting type (Surface Mount). No circuit modifications are required.

Q2: What is the significance of the thermal resistance variation between substitute parts?

A: Thermal resistance values range from 14°C/W to 16°C/W across the substitute group. This variation represents acceptable engineering tolerance in package thermal performance. For applications with standard thermal management, all variants perform equivalently. Applications requiring optimized thermal performance should select SPMWHT541MP5WAVSS4 (14°C/W).

Q3: Why is SPMWHT541MP5WAVRS4 classified as "Not For New Designs"?

A: This classification indicates the part has reached end-of-life status and is no longer recommended for new product development. Active equivalent parts (SPMWHT541MP5WAVMS4, SPMWHT541MP5WAV0S4, SPMWHT541MP5WAVNS4, SPMWHT541MP5WAVKS4, SPMWHT541MP5WAVSS4) should be used for new designs to ensure long-term supply availability and continued manufacturer support.

Q4: Are there differences in RoHS compliance between substitute parts?

A: Substitute parts carry either RoHS Compliant or ROHS3 Compliant certifications. ROHS3 Compliant variants (SPMWHT541MP5WAVMS4 and SPMWHT541MP5WAVSS4) represent enhanced compliance standards. Both certifications satisfy standard RoHS requirements. Selection should align with specific regulatory requirements of the end application.

Q5: How do inventory levels affect part selection?

A: Inventory availability varies significantly: SPMWHT541MP5WAV0S4 (85,670 units), SPMWHT541MP5WAVMS4 (50,200 units), SPMWHT541MP5WAVNS4 (1,011 units), SPMWHT541MP5WAVSS4 (877 units), and SPMWHT541MP5WAVKS4 (795 units). For high-volume production, SPMWHT541MP5WAV0S4 or SPMWHT541MP5WAVMS4 are recommended. For lower-volume applications, all variants provide adequate supply.

Q6: Can substitute parts be mixed in the same production batch?

A: All substitute parts maintain identical electrical and mechanical specifications. Mixing is permissible from a functional standpoint. However, manufacturing best practices recommend standardizing on a single part number per production batch to maintain traceability and simplify quality control documentation.

Q7: What packaging format is used for these LED components?

A: All parts are supplied in Tape & Reel (TR) format, standard for surface mount LED components. The 5630 package designation refers to the supplier device package configuration. Tape & Reel packaging is compatible with automated pick-and-place assembly equipment.

Q8: Are there any REACH compliance considerations?

A: SPMWHT541MP5WAVSS4 carries explicit REACH Unaffected certification. Other variants do not specify REACH status in provided documentation. For applications requiring REACH compliance verification, SPMWHT541MP5WAVSS4 is the documented choice.
