Substitute Part Grouping Explanation
Substitution logic is based on the following criteria derived from provided data:
- Manufacturer origin (Seoul Semiconductor Inc. or equivalent manufacturers)
- Product status (Active preferred over Obsolete)
- RoHS3 compliance and regulatory alignment
- ECCN and HTSUS classification consistency
- LED package type and form factor (SMD variants including 3030, 5050, 5630)
- Color temperature specifications where documented (4000K, 5000K, 5700K, 6500K)
- CRI rating where applicable (80CRI variants)
Active Seoul Semiconductor parts (S1-STW8Q14C, S1-STW8Q14D, S3-STW8Q14C) represent direct parametric equivalents. The S1W0 series (3030 and 5050 packages) and SAW0L60A-EA provide alternative form factors. The Broadcom ASMW-FWG0-ZKMB6 represents a cross-manufacturer substitute with PLCC packaging.

Engineering Selection Recommendations
For applications requiring S2-STW8Q14C replacement, the following selection hierarchy is based on product status and regulatory compliance:
Primary Equivalents (Active Status, Same Manufacturer):
- S1-STW8Q14C and S1-STW8Q14D are active Seoul Semiconductor parts with 80CRI 5630 specifications, offering direct functional replacement with improved product lifecycle status.
- S3-STW8Q14C provides an alternative active variant from the same manufacturer with equivalent specifications.
Alternative Form Factors (Active Status, Same Manufacturer):
- S1W0 series parts (3030 and 5050 packages) are active alternatives with defined color temperature ratings (4000K, 5000K, 5700K, 6500K) and Tape & Reel packaging. These accommodate different PCB layout requirements.
- S1W0-5050408006-0000005S-00002 offers the highest inventory availability (11,787 pcs) among active alternatives.
Cross-Manufacturer Alternative:
- ASMW-FWG0-ZKMB6 from Broadcom Limited is an active PLCC SMD LED meeting ROHS3 compliance and EAR99 classification, suitable for applications permitting cross-manufacturer substitution.
All recommended parts maintain ROHS3 compliance, EAR99 ECCN classification, and 8541.41.0000 HTSUS code consistency with the original component.
Frequently Asked Questions (FAQ)
Q: Can S1-STW8Q14C and S1-STW8Q14D be used interchangeably with S2-STW8Q14C?
A: Both S1-STW8Q14C and S1-STW8Q14D are active Seoul Semiconductor parts with 80CRI 5630 specifications. They are functionally equivalent to the obsolete S2-STW8Q14C based on provided parameters. Selection between them depends on specific design requirements not detailed in the parameter set.
Q: What is the difference between 5630 and 5050 package variants?
A: The package designation indicates physical form factor. The 5630 variants (S1-STW8Q14C, S1-STW8Q14D, S3-STW8Q14C) and 5050 variants (S1W0 series) represent different SMD package sizes. Selection depends on PCB layout constraints and thermal management requirements specific to the application.
Q: Are the S1W0 3030 and 5050 series suitable replacements?
A: The S1W0 series parts are active alternatives with defined color temperature specifications (4000K, 5000K, 5700K, 6500K). They represent different package form factors and may require PCB layout modifications. Compatibility depends on application-specific thermal and optical requirements.
Q: Why is SAW0L60A-EA listed if it is obsolete?
A: SAW0L60A-EA is included as a documented substitute relationship from the original part data. Although obsolete, it maintains ROHS3 compliance and significant inventory availability (26,065 pcs). It is suitable only for applications where existing stock is available and lifecycle concerns are acceptable.
Q: Can the Broadcom ASMW-FWG0-ZKMB6 replace Seoul Semiconductor parts?
A: ASMW-FWG0-ZKMB6 is an active cross-manufacturer alternative with PLCC packaging. It meets ROHS3 compliance and regulatory classification consistency. Cross-manufacturer substitution requires verification of optical, thermal, and electrical compatibility specific to the application design.
Q: What does Moisture Sensitivity Level (MSL) 2A indicate?
A: MSL 2A (4 Weeks) applies to S1W0 series and SAW0L60A-EA parts. This indicates the component can be exposed to moisture for up to 4 weeks at specified conditions before soldering. Proper storage and handling procedures must be followed to maintain component integrity.
