Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS90CF384ASLC is determined by strict alignment of the following critical parameters:

• Base product number (DS90CF384) ensures functional equivalence at the silicon level
• Voltage supply range (3V ~ 3.6V) maintains electrical compatibility
• Mounting type (Surface Mount) ensures PCB assembly compatibility
• Moisture sensitivity level (MSL 2, 1 Year) defines storage and handling requirements
• RoHS and REACH compliance status for regulatory alignment

The substitute part DS90CF384AMTD/NOPB shares the identical base product number and electrical specifications, confirming functional equivalence. The primary difference lies in package configuration and product status, with the substitute offering an active product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The DS90CF384AMTD/NOPB serves as the manufacturer-recommended substitute for the obsolete DS90CF384ASLC. Both components share identical base product designation and electrical operating parameters, confirming functional compatibility at the circuit level.

The substitute component offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the DS90CF384AMTD/NOPB achieves ROHS3 compliance, providing enhanced regulatory alignment compared to the non-compliant original part.

The package transition from 64-NFBGA (8x8) to 56-TSSOP represents a physical footprint change that requires PCB layout modification. This substitution is appropriate for new designs or system revisions where layout redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can DS90CF384AMTD/NOPB be used as a direct drop-in replacement for DS90CF384ASLC?

A: Functional compatibility is confirmed through identical base product number and electrical specifications. However, the package change from 64-NFBGA (8x8) to 56-TSSOP requires PCB layout modification and is not a direct physical replacement.

Q: What are the key compatibility criteria for this substitution?

A: Compatibility is established through: matching base product number (DS90CF384), identical supply voltage range (3V ~ 3.6V), equivalent moisture sensitivity level (MSL 2), and surface mount mounting type. Package differences necessitate design revision.

Q: How does the RoHS compliance difference affect substitution?

A: The substitute part achieves ROHS3 compliance while the original is non-compliant. This difference is advantageous for applications subject to RoHS regulations and does not create compatibility issues.

Q: Are there any storage or handling differences between these parts?

A: Both components share identical moisture sensitivity level (MSL 2, 1 Year), indicating equivalent storage and handling requirements. Standard MSL 2 precautions apply to both parts.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status ensures continued manufacturing availability, technical support, and supply chain reliability. This eliminates obsolescence risk associated with the original part.
