Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS1893AFT is determined by strict alignment of the following electrical and mechanical parameters:

Protocol and Function: Both the main part and substitute must operate as Ethernet Physical Layer Controllers supporting 10/100 Base-T/TX PHY standards with parallel interface connectivity.

Electrical Specifications: Voltage supply range (3.14V ~ 3.47V) and operating temperature range (0°C ~ 70°C) must be identical or encompassing.

Package Compatibility: The 48-BSSOP (0.295", 7.50mm Width) package specification must match exactly to ensure PCB layout and assembly compatibility.

Manufacturer Consistency: Parts from Renesas Electronics Corporation within the PHYceiver™ series maintain design and performance consistency.

The substitute part 1893CFLFT meets all these criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 1893CFLFT is a direct functional equivalent to the ICS1893AFT with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The ICS1893AFT is obsolete, while the 1893CFLFT maintains active product status with ongoing manufacturer support and availability.

Regulatory Compliance: The 1893CFLFT is ROHS3 compliant, whereas the ICS1893AFT is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the 1893CFLFT is the appropriate selection.

Supply Chain Availability: The 1893CFLFT has higher inventory levels (1964 Pcs) compared to the ICS1893AFT (1268 Pcs), supporting sustained production requirements.

Moisture Sensitivity: The 1893CFLFT has MSL 3 (168 Hours) versus MSL 1 (Unlimited) for the ICS1893AFT. Storage and handling procedures must account for this difference in moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the 1893CFLFT directly replace the ICS1893AFT in existing designs?

A: Yes. Both parts share identical electrical specifications (3.14V ~ 3.47V supply, 0°C ~ 70°C operating range), functional characteristics (Ethernet Physical Layer Controller, 10/100 Base-T/TX PHY), interface type (Parallel), and package geometry (48-BSSOP). Direct substitution is electrically and mechanically compatible.

Q: What is the significance of the RoHS compliance difference?

A: The ICS1893AFT is RoHS non-compliant, while the 1893CFLFT is ROHS3 compliant. For new designs or applications subject to RoHS directives, the 1893CFLFT is required. For legacy systems already using non-compliant components, either part may be acceptable depending on regulatory jurisdiction and customer requirements.

Q: How does the Moisture Sensitivity Level (MSL) difference affect handling?

A: The ICS1893AFT has MSL 1 (Unlimited), allowing indefinite storage without moisture exposure concerns. The 1893CFLFT has MSL 3 (168 Hours), requiring controlled storage conditions and limiting the time the component can be exposed to ambient humidity before soldering. Proper baking procedures must be followed if the 1893CFLFT exceeds its MSL exposure window.

Q: Are both parts from the same manufacturer?

A: Yes. Both the ICS1893AFT and 1893CFLFT are manufactured by Renesas Electronics Corporation and belong to the PHYceiver™ series, ensuring design consistency and performance alignment.

Q: What parameters determine substitution eligibility for Ethernet PHY controllers?

A: Substitution eligibility is determined by: Protocol and function (Ethernet Physical Layer Controller), Standards compliance (10/100 Base-T/TX PHY), Interface type (Parallel), Electrical specifications (Voltage supply and operating temperature ranges), and Package geometry (48-BSSOP). All parameters must match or be compatible for direct substitution.
