Substitute Part Grouping Explanation

Substitute parts for the SPMWHT325AD5YBVMS0 are identified based on the following critical parameters that determine functional equivalence:

Color and CCT Matching: Both the main part and substitute must operate at warm white 3000K color temperature with CRI of 80 to maintain consistent color rendering in lighting applications.

Electrical Compatibility: Forward voltage (Vf), test current, and maximum current ratings must fall within acceptable operating ranges. The substitute part L130-3080003000W21 operates at 6.1V with 120mA test current, representing a minor increase in voltage and current within acceptable design tolerances for warm white LED applications.

Luminous Output: Flux output at 25°C and lumens-per-watt efficiency must be comparable. The substitute delivers 90 lumens at 120mA test current with 123 lm/W efficiency, exceeding the main part's 66 lumens at 100mA and 111 lm/W.

Thermal Characteristics: Thermal resistance of the package affects heat dissipation performance. The substitute's 12°C/W thermal resistance is superior to the main part's 15°C/W.

Mechanical Form Factor: Surface mount packaging and physical dimensions must accommodate existing PCB layouts. The substitute uses a 1212 (3030 Metric) package measuring 3.00 mm × 3.00 mm with 0.62 mm seated height, compared to the main part's 3623 package at 3.60 mm × 2.30 mm with 0.70 mm height. These dimensional differences require PCB footprint verification.

Regulatory Compliance: Both parts maintain RoHS compliance and EAR99 ECCN classification, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT325AD5YBVMS0 is classified as obsolete, making the L130-3080003000W21 a necessary alternative for new designs and production continuity. The substitute part is in active production status, ensuring long-term availability and supply chain stability.

Regulatory and Compliance Alignment: Both parts maintain RoHS compliance and EAR99 ECCN classification. The substitute achieves ROHS3 compliance, representing alignment with current regulatory standards. No compliance barriers exist for substitution.

Electrical Parameter Assessment: The substitute operates at 6.1V forward voltage versus 5.96V for the main part, representing a 0.14V increase. This minor difference is within typical design tolerances for LED driver circuits. The substitute's 120mA test current versus 100mA for the main part requires driver circuit verification to confirm current source capability. Both parts operate within acceptable voltage and current ranges for warm white LED applications.

Thermal Performance: The substitute's 12°C/W thermal resistance is superior to the main part's 15°C/W, providing improved heat dissipation. This enhancement supports higher reliability in thermally constrained applications.

Mechanical and Packaging Constraints: The substitute uses a 1212 (3030 Metric) package measuring 3.00 mm × 3.00 mm, compared to the main part's 3623 package at 3.60 mm × 2.30 mm. PCB footprint redesign is required for substitution. The substitute's lower profile (0.62 mm versus 0.70 mm) may provide design advantages in space-constrained applications.

Luminous Output: The substitute delivers 90 lumens at 120mA test current, exceeding the main part's 66 lumens at 100mA. This increased output supports applications requiring higher brightness levels while maintaining 3000K warm white color temperature and 80 CRI.

Frequently Asked Questions (FAQ)

Q: Can the L130-3080003000W21 directly replace the SPMWHT325AD5YBVMS0 without PCB modifications?

A: No. The substitute uses a different package footprint (1212/3030 Metric versus 3623). PCB layout redesign is required to accommodate the new package dimensions and pad configuration. Physical dimensions differ: the substitute measures 3.00 mm × 3.00 mm compared to 3.60 mm × 2.30 mm for the main part.

Q: What is the impact of the 0.14V forward voltage difference between the two parts?

A: The substitute operates at 6.1V versus 5.96V for the main part. This 0.14V increase is within typical design tolerances for LED driver circuits. Existing constant-current driver designs will accommodate this minor voltage variation without circuit modification.

Q: Does the substitute's higher test current (120mA versus 100mA) require driver circuit changes?

A: Driver circuit verification is necessary. If the existing design uses a constant-current source rated for 100mA, operation at 120mA test current must be confirmed within the driver's output range. The substitute's maximum current rating of 240mA provides design margin for typical LED driver implementations.

Q: Are there moisture sensitivity differences between the two parts?

A: Yes. The main part carries MSL 2A (4 Weeks), while the substitute is rated MSL 3 (168 Hours). The main part requires more stringent moisture control during storage and handling. The substitute's higher MSL rating provides greater flexibility in manufacturing environments.

Q: What are the advantages of the substitute's improved thermal resistance (12°C/W versus 15°C/W)?

A: Lower thermal resistance improves heat dissipation from the LED junction to the PCB. This enhancement reduces junction temperature at equivalent power levels, supporting higher reliability and extended operational life in thermally constrained applications.

Q: Does the substitute's higher luminous output (90 lm versus 66 lm) affect circuit design?

A: The substitute delivers 36% higher luminous output at its test current. Existing designs may require optical or electrical adjustments to maintain target brightness levels. Constant-current driver designs will automatically regulate the substitute's output through current control.

Q: Are both parts suitable for the same warm white lighting applications?

A: Yes. Both parts operate at 3000K color temperature with 80 CRI, maintaining identical color rendering characteristics. The substitute's higher efficiency (123 lm/W versus 111 lm/W) and improved thermal performance make it suitable for equivalent or enhanced warm white lighting applications.

Q: What is the significance of the substitute being in active production status?

A: Active production status ensures long-term availability, consistent supply, and ongoing manufacturer support. The main part's obsolete status creates supply risk and potential discontinuation. The substitute provides design security for new products and production continuity.
