Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS1893BFI is determined by the following critical parameters:

• Manufacturer & Series: All substitutes must be from Renesas Electronics Corporation PHYceiver™ series to ensure design compatibility and pin configuration alignment
• Functional Specification: Physical Layer Controller function with 10/100 Base-T/TX PHY standards and Parallel interface must be maintained
• Package Compatibility: 48-BSSOP package with 0.295" width (7.50mm) is mandatory for PCB layout compatibility
• Electrical Parameters: Supply voltage range 3.14V ~ 3.47V must be supported
• Interface Protocol: Ethernet protocol with parallel interface connectivity must be preserved

Two substitute parts meet these criteria: 1893BFILF (Direct Manufacturer Part) and 1893CFLF (Parametric Equivalent).

Parameter Comparison

Engineering Selection Recommendations

1893BFILF is the Direct Manufacturer Part substitute. This part is currently Active in production status and offers an extended operating temperature range of -40°C to 85°C compared to the original ICS1893BFI specification of 0°C to 70°C. The 1893BFILF achieves ROHS3 compliance and is supplied in Tube packaging. This part is suitable for applications requiring broader temperature performance or compliance with modern environmental standards.

1893CFLF is the Parametric Equivalent substitute. This part maintains the original operating temperature range of 0°C to 70°C and is currently Active in production status. The 1893CFLF also achieves ROHS3 compliance and is supplied in Tube packaging. This part provides direct functional equivalence with improved compliance characteristics while preserving the thermal specifications of the original design.

Both substitute parts are manufactured by Renesas Electronics Corporation and maintain identical electrical, functional, and package specifications as the ICS1893BFI. Selection between these two substitutes depends on application-specific temperature requirements and compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can 1893BFILF and 1893CFLF be used interchangeably with ICS1893BFI?

A: Both parts are functionally equivalent substitutes for the ICS1893BFI within their specified operating parameters. They share identical package geometry, electrical specifications, protocol support, and interface characteristics. Selection depends on application temperature range requirements.

Q: What is the primary difference between 1893BFILF and 1893CFLF?

A: The primary difference is operating temperature range. The 1893BFILF operates from -40°C to 85°C, providing extended temperature capability. The 1893CFLF operates from 0°C to 70°C, matching the original ICS1893BFI specification. Both parts are ROHS3 compliant and Active in production.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use identical 48-BSSOP packaging with 0.295" width (7.50mm). PCB layouts, footprints, and mounting requirements remain unchanged.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: The ICS1893BFI has MSL 1 (Unlimited), while both substitutes have MSL 3 (168 Hours). MSL 3 requires controlled storage and handling conditions with a 168-hour floor life after moisture exposure. Proper moisture management procedures must be implemented during component storage and assembly.

Q: Why is the ICS1893BFI listed as Obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Renesas Electronics Corporation. The 1893BFILF and 1893CFLF are Active alternatives that provide equivalent functionality with current production support and compliance certifications.

Q: Are all three parts RoHS compliant?

A: The ICS1893BFI is RoHS non-compliant. Both substitute parts (1893BFILF and 1893CFLF) are ROHS3 compliant, meeting current environmental and regulatory requirements.
