Substitute Part Grouping Explanation

Substitution of the ICS1893CFIT is determined by strict equivalence across the following critical parameters:

• Protocol and Standards: Both parts must support Ethernet 10/100 Base-T/TX PHY
• Interface Type: Parallel interface connectivity required
• Voltage Supply Range: 3.14V ~ 3.47V
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 48-BSSOP (0.295", 7.50mm Width)
• Supplier Device Package: 48-SSOP

The substitute part 1893BFILFT meets all these electrical and mechanical parameters, establishing it as a parametric equivalent. The primary distinction between the main part and substitute relates to product status, packaging format, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 1893BFILFT serves as the active production equivalent to the obsolete ICS1893CFIT. Both components share identical electrical specifications and physical packaging, ensuring direct functional compatibility in 10/100 Ethernet PHY applications.

Selection between these parts should be based on:

• Product Status: The 1893BFILFT is active production, while ICS1893CFIT is obsolete. New designs should specify 1893BFILFT.
• Compliance Requirements: The 1893BFILFT meets ROHS3 compliance, whereas ICS1893CFIT is RoHS non-compliant. Applications subject to RoHS regulations must use 1893BFILFT.
• Packaging Format: ICS1893CFIT is supplied in tube packaging; 1893BFILFT is supplied in Tape & Reel format. Procurement and assembly processes may influence selection based on available handling equipment.
• Moisture Sensitivity: ICS1893CFIT has MSL 1 (unlimited shelf life); 1893BFILFT has MSL 3 (168-hour limit). Storage and handling procedures must account for the higher moisture sensitivity of the substitute.

Frequently Asked Questions (FAQ)

Q: Can 1893BFILFT directly replace ICS1893CFIT in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: Ethernet 10/100 Base-T/TX PHY protocol, parallel interface, 3.14V–3.47V supply voltage, -40°C to 85°C operating range, and 48-SSOP packaging. Pin-to-pin compatibility is maintained.

Q: What is the primary reason to transition from ICS1893CFIT to 1893BFILFT?

A: The ICS1893CFIT is obsolete. The 1893BFILFT is the active production equivalent from Renesas Electronics Corporation, ensuring long-term availability and supply chain continuity.

Q: Are there compliance differences between these parts?

A: Yes. The 1893BFILFT is ROHS3 compliant, while ICS1893CFIT is RoHS non-compliant. Applications requiring RoHS certification must use 1893BFILFT.

Q: How do packaging formats differ?

A: ICS1893CFIT is supplied in tube packaging; 1893BFILFT is supplied in Tape & Reel (TR) format. This affects procurement quantities, handling, and automated assembly compatibility.

Q: What is the moisture sensitivity difference, and does it affect application suitability?

A: ICS1893CFIT has MSL 1 (unlimited shelf life); 1893BFILFT has MSL 3 (168-hour limit at 85°C/60% RH). The substitute requires stricter moisture control during storage and handling. Applications with extended storage periods or high-humidity environments must implement appropriate moisture management protocols.

Q: Are both parts from the same manufacturer?

A: Yes. Both ICS1893CFIT and 1893BFILFT are manufactured by Renesas Electronics Corporation, ensuring consistent design and performance characteristics.
