Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1893AFILFT is determined by the following critical parameters:

• Manufacturer: Renesas Electronics Corporation (same manufacturer ensures design continuity)
• Protocol & Standards: Ethernet 10/100 Base-T/TX PHY (functional equivalence requirement)
• Interface Type: Parallel (electrical interface compatibility)
• Package / Case: 48-BSSOP (0.295", 7.50mm Width) (mechanical and pin compatibility)
• Voltage Supply Range: 3.14V ~ 3.47V (power supply compatibility)
• Operating Temperature Range: -40°C ~ 85°C (thermal operating envelope)

The 1893BFILFT meets all substitution criteria as a direct equivalent component. Both parts share identical electrical specifications, functional characteristics, and physical packaging requirements. The primary distinction is product status: the 1893AFILFT is obsolete while the 1893BFILFT is active, with updated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 1893BFILFT is the direct substitute for the obsolete 1893AFILFT. Selection of the 1893BFILFT is supported by:

• Functional Equivalence: Identical Ethernet Physical Layer Controller specifications for 10/100 Base-T/TX applications
• Electrical Compatibility: Matching voltage supply range (3.14V ~ 3.47V) and operating temperature envelope (-40°C ~ 85°C)
• Physical Compatibility: Identical 48-BSSOP package footprint and pin configuration
• Active Product Status: The 1893BFILFT maintains active production status with current manufacturer support
• Compliance Certification: ROHS3 compliance on the 1893BFILFT provides updated environmental and regulatory alignment

For applications requiring the 1893AFILFT, transition to the 1893BFILFT requires no circuit redesign or layout modification. Both components are pin-compatible and functionally equivalent within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1893BFILFT directly replace the 1893AFILFT in existing designs?

A: Yes. The 1893BFILFT is a direct pin-compatible and functionally equivalent substitute. No circuit modifications or PCB layout changes are required for substitution.

Q: What is the difference between the 1893AFILFT and 1893BFILFT?

A: Both components are Ethernet Physical Layer Controllers with identical electrical specifications and 48-SSOP packaging. The primary differences are product status (1893AFILFT is obsolete; 1893BFILFT is active) and compliance certifications (1893BFILFT includes ROHS3 compliance).

Q: Are the supply voltage requirements identical between these parts?

A: Yes. Both the 1893AFILFT and 1893BFILFT operate within the same voltage supply range of 3.14V ~ 3.47V.

Q: Do these components have the same operating temperature range?

A: Yes. Both components operate across the temperature range of -40°C ~ 85°C.

Q: Is the 48-SSOP package footprint identical for both parts?

A: Yes. Both components use the 48-BSSOP package (0.295", 7.50mm Width) with identical pin configuration and mechanical dimensions.

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

A: The 1893AFILFT has MSL 1 (Unlimited), while the 1893BFILFT has MSL 3 (168 Hours). This affects storage and handling procedures but does not impact electrical performance or substitution compatibility.

Q: Is the 1893BFILFT available in the same packaging format?

A: The 1893BFILFT is supplied in Tape & Reel (TR) format, while the 1893AFILFT packaging format is not specified. Both use the same 48-SSOP device package for component functionality.
