Substitute Part Grouping Explanation

Substitution eligibility for the SI2415-C-FS is determined by strict alignment across the following critical parameters:

• Manufacturer & Series: Must be Skyworks Solutions Inc. ISOmodem® series to ensure protocol compatibility and electrical characteristics
• Data Format Support: Must support all protocols: V.21, V.22, V.23, V.29, V.32, Bell 103, Bell 212A
• Baud Rate: Must operate at 2.4k baud rate
• Voltage Supply Range: Must operate within 3V ~ 3.6V
• Package / Case: Must be 16-SOIC (0.154", 3.90mm Width) for PCB layout compatibility
• Mounting Type: Must be Surface Mount
• Moisture Sensitivity Level: Must be MSL 3 (168 Hours)
• Base Product Number: Must share SI2415 base product number

The SI2415-D-FS meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SI2415-D-FS is the direct substitute for the SI2415-C-FS. Both parts share identical electrical specifications, protocol support, baud rate capability, supply voltage range, and physical packaging. The primary distinction is product lifecycle status: the SI2415-C-FS is designated "Not For New Designs," while the SI2415-D-FS maintains "Active" status.

For applications requiring the SI2415-C-FS, the SI2415-D-FS provides functional and mechanical equivalence with the advantage of current manufacturer support and availability. Both parts carry identical HTSUS classification (8542.39.0001), confirming regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the SI2415-D-FS directly replace the SI2415-C-FS in existing designs?

A: Yes. The SI2415-D-FS is a direct substitute. Both parts are identical in electrical performance, protocol support, supply voltage, baud rate, package type, and physical dimensions. No circuit modifications are required.

Q: What is the significance of the "Not For New Designs" status on the SI2415-C-FS?

A: This designation indicates the manufacturer has discontinued active development and support for this part number. The SI2415-D-FS, with "Active" status, represents the current equivalent in the product line.

Q: Are there any differences in moisture sensitivity handling between these parts?

A: No. Both the SI2415-C-FS and SI2415-D-FS carry identical Moisture Sensitivity Level 3 (168 Hours) ratings, requiring the same storage and handling protocols.

Q: Will the SI2415-D-FS fit the same PCB footprint as the SI2415-C-FS?

A: Yes. Both parts use the 16-SOIC (0.154", 3.90mm Width) package with surface mount configuration, ensuring identical PCB layout compatibility.

Q: Are there compliance or export differences between these part numbers?

A: The SI2415-C-FS carries ECCN 5A991B2, while the SI2415-D-FS carries ECCN EAR99. Both share the same HTSUS code (8542.39.0001). Verify export compliance requirements for your specific application and jurisdiction.
