Renesas Electronics 1893BFLF Ethernet Physical Layer Controller - Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 1893BFLF is an Ethernet Physical Layer Controller designed for 10/100 Base-T/TX applications with parallel interface connectivity. This component operates as a PHYceiver™ series device in a 48-SSOP package configuration. The 1893BFLF is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1893BFLF is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Protocol: Ethernet
• Function: Physical Layer Controller
• Interface: Parallel
• Standards: 10/100 Base-T/TX PHY
• Voltage Supply: 3.14V ~ 3.47V
• Operating Temperature: 0°C ~ 70°C

Mechanical & Compliance Specifications:

• Package Type: 48-BSSOP (0.295", 7.50mm Width)
• Supplier Device Package: 48-SSOP
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)
• REACH Status: REACH Unaffected

The 1893CFLF meets all specified electrical and mechanical parameters, establishing it as a parametric equivalent. The primary distinction is product status: the 1893BFLF is obsolete while the 1893CFLF is active, making the latter the recommended substitute for ongoing procurement and new designs.

Parameter Comparison

Engineering Selection Recommendations

The 1893CFLF is the direct substitute for the obsolete 1893BFLF. Both components share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The 1893CFLF maintains active product status with Renesas Electronics Corporation, ensuring continued availability and manufacturing support.

Selection of the 1893CFLF is appropriate for:

• Direct replacement in existing designs using the 1893BFLF
• New designs requiring 10/100 Base-T/TX Ethernet PHY functionality with parallel interface
• Applications requiring ROHS3 compliance and REACH unaffected status
• Systems operating within the 3.14V to 3.47V supply voltage range and 0°C to 70°C temperature envelope

The 1893CFLF is supplied in tube packaging, which may differ from the original procurement format of the 1893BFLF. Verify packaging requirements for your procurement and assembly processes.
