Substitute Part Grouping Explanation

Substitution eligibility for the DS250DF230ZLSR is determined by alignment across the following critical parameters:

Primary Substitution Criteria:

• Functional category classification (Interface)
• Active product status
• Export control classification (ECCN: EAR99)
• Harmonized tariff code alignment (HTSUS: 8542.39.0001)
• RoHS3 compliance certification
• Surface mount mounting capability

The FSA644UCX from Fairchild Semiconductor qualifies as a substitute based on matching category, active status, identical export control and tariff classifications, and surface mount compatibility. Both components operate within the interface semiconductor category and maintain equivalent regulatory compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

Selection between the DS250DF230ZLSR and FSA644UCX should be based on the following engineering factors:

DS250DF230ZLSR is the primary component choice when RoHS3 compliance certification is a mandatory design requirement. This part carries explicit ROHS3 Compliant status and is currently in active production with 1023 units available in inventory.

FSA644UCX serves as a functional substitute when supply availability is the determining factor. This component maintains identical export control and tariff classifications, operates as an active product, and supports surface mount assembly processes. Current inventory availability is 29082 units.

Both components satisfy EAR99 export control requirements and fall under the same harmonized tariff classification, making them interchangeable from regulatory and compliance perspectives. The selection decision should prioritize design specification requirements, particularly regarding RoHS certification status and specific package requirements for your application.

Frequently Asked Questions (FAQ)

Q: Can FSA644UCX directly replace DS250DF230ZLSR in all applications?

A: Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications and operate as active interface semiconductors with surface mount compatibility. Substitution is valid from regulatory and compliance standpoints. Verify that application-specific functional requirements align with FSA644UCX specifications.

Q: What is the significance of the 36-NFBGA (5x5) package specification?

A: The 36-NFBGA (5x5) designation indicates a 36-ball ball grid array package in a 5mm x 5mm footprint. This package specification is critical for PCB layout and assembly compatibility. Confirm that substitute components support equivalent package footprints and ball pitch specifications for your manufacturing process.

Q: Does RoHS3 compliance status affect substitution decisions?

A: RoHS3 compliance is explicitly stated for DS250DF230ZLSR. If your design or regulatory environment mandates RoHS3 certification, this requirement must be verified for any substitute component. The input data does not specify RoHS status for FSA644UCX.

Q: Are there inventory considerations when selecting between these parts?

A: DS250DF230ZLSR has 1023 units in current inventory, while FSA644UCX has 29082 units available. Inventory levels may influence component selection when supply chain continuity is a factor in design decisions.

Q: What export control implications apply to these components?

A: Both DS250DF230ZLSR and FSA644UCX are classified under ECCN EAR99, which designates them as items subject to the Export Administration Regulations but not requiring a license for most destinations. This classification is identical for both components.
