Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS1893BFIT is determined by strict alignment across the following critical parameters:

• Ethernet protocol and 10/100 Base-T/TX PHY standards compliance
• Parallel interface architecture
• Supply voltage range: 3.14V ~ 3.47V
• Operating temperature range: -40°C ~ 85°C
• Physical Layer Controller function
• 48-BSSOP package configuration

The substitute part 1893BFILFT meets all these criteria. The primary distinction between the main part and its substitute is product status and packaging format, with the substitute available in Tape & Reel configuration and classified as active product status.

Parameter Comparison

Engineering Selection Recommendations

The 1893BFILFT serves as the direct functional equivalent to the ICS1893BFIT for all electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The ICS1893BFIT is obsolete, while 1893BFILFT maintains active product status with confirmed inventory availability. For new designs or long-term system support, 1893BFILFT is the appropriate selection.

Compliance Requirements: The 1893BFILFT achieves ROHS3 compliance, whereas the ICS1893BFIT is non-compliant. Applications subject to RoHS regulations require the substitute part.

Packaging and Handling: The 1893BFILFT is supplied in Tape & Reel format with MSL 3 rating (168 hours), compared to bulk packaging with MSL 1 for the main part. Tape & Reel packaging is standard for automated assembly processes and provides defined moisture exposure windows.

Electrical and Thermal Performance: Both parts operate identically across voltage supply range, temperature range, and functional specifications, ensuring direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can 1893BFILFT replace ICS1893BFIT in existing designs?

A: Yes. Both parts share identical electrical specifications, interface architecture, and package dimensions. Direct substitution is possible without circuit modification.

Q: What is the primary reason to transition from ICS1893BFIT to 1893BFILFT?

A: The ICS1893BFIT is classified as obsolete product. The 1893BFILFT is the active equivalent, ensuring continued availability and supply chain reliability.

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

A: Yes. The ICS1893BFIT has MSL 1 (unlimited moisture exposure), while 1893BFILFT has MSL 3 (168-hour limit). The substitute requires controlled storage conditions and has a defined moisture exposure window before soldering.

Q: Does the Tape & Reel packaging of 1893BFILFT affect compatibility?

A: No. Tape & Reel is a packaging and delivery format only. The component itself, pin configuration, and electrical performance remain identical to bulk-packaged versions.

Q: Is RoHS compliance a functional difference?

A: No. RoHS compliance reflects manufacturing process and material composition, not electrical function. The 1893BFILFT meets ROHS3 standards, making it suitable for regulated markets and applications with environmental compliance requirements.

Q: Can both parts be used interchangeably in procurement?

A: For new procurement, 1893BFILFT is recommended due to active status and compliance certifications. Existing stock of ICS1893BFIT may be used in applications without RoHS requirements, but transition planning to the substitute is advised.
