Substitute Part Grouping Explanation
Substitution logic is based on the following criteria derived from provided parameters:
- Manufacturer alignment (Seoul Semiconductor Inc. primary source)
- Product status (Active alternatives preferred over obsolete)
- RoHS3 compliance (mandatory for equivalent substitution)
- ECCN and HTSUS classification consistency (EAR99 / 8541.41.0000)
- LED lighting category classification
- Packaging format compatibility (SMD variants)
Substitute parts are grouped into two categories: Seoul Semiconductor Inc. direct equivalents (5630 and 3030 form factors, 5050 package variants) and cross-manufacturer alternatives (Broadcom Limited PLCC SMD).

Engineering Selection Recommendations
For applications currently using E2-STW9Q14D, the following selection criteria apply:
Primary Substitutes (Seoul Semiconductor Inc., Active Status):
- S1-STW8Q14C and S1-STW8Q14D are active 5630 form factor alternatives with 80CRI specification
- S3-STW8Q14C provides equivalent 5630 form factor with active product status
- All maintain ROHS3 compliance and EAR99 classification
Secondary Substitutes (Seoul Semiconductor Inc., 3030 and 5050 Form Factors):
- S1W0-3030578003-0000003S-0P004 (5700K) and S1W0-3030658003-0000003S-0P004 (6500K) offer 3030 SMD packaging with active status
- S1W0-5050408006-0000005S-00002, S1W0-5050508006-0000005S-00002, and S1W0-5050578006-0000005S-00002 provide 5050 package variants with high inventory availability
Cross-Manufacturer Alternative:
- ASMW-FWG0-ZKMB6 (Broadcom Limited) is an active PLCC SMD LED with ROHS3 compliance for applications permitting manufacturer substitution
All substitute parts maintain ROHS3 compliance, EAR99 ECCN classification, and HTSUS code 8541.41.0000 consistency with the original part.
Frequently Asked Questions (FAQ)
Q: Why is E2-STW9Q14D classified as obsolete? A: The E2-STW9Q14D has reached end-of-life status. Active alternatives from Seoul Semiconductor Inc. are available to maintain design continuity and supply chain stability.
Q: What is the primary difference between 5630 and 3030 form factor substitutes? A: Form factor refers to the physical package dimensions. 5630 and 3030 are different SMD package sizes. Selection depends on PCB layout constraints and thermal management requirements of the target application.
Q: Are 5050 package LEDs compatible with 5630 designs? A: 5050 represents a different package footprint. Mechanical compatibility requires PCB redesign. Electrical compatibility depends on forward voltage and current specifications, which are not provided in this reference.
Q: Can Broadcom ASMW-FWG0-ZKMB6 replace Seoul Semiconductor parts directly? A: ASMW-FWG0-ZKMB6 is a cross-manufacturer alternative. Direct substitution requires verification of electrical parameters, package footprint compatibility, and thermal characteristics specific to your application.
Q: What does ROHS3 compliance mean for substitution? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. All listed substitutes maintain this compliance level, ensuring regulatory consistency.
Q: Why do some substitutes have Tape & Reel packaging while others show "-"? A: Packaging format indicates supply configuration. Tape & Reel (TR) is standard for high-volume production. The "-" notation indicates packaging information was not provided in the source data.
Q: Which substitute has the highest inventory availability? A: S1W0-5050408006-0000005S-00002 (4000K 5050) has 11,787 pieces in stock, followed by SAW0L60A-EA with 26,065 pieces. Note that SAW0L60A-EA is classified as obsolete despite high inventory.
