ICS1893CFI Equivalent & Substitute Parts

Part Overview

The ICS1893CFI is an Ethernet Physical Layer Controller designed for 10/100 Base-T/TX applications with parallel interface connectivity. Manufactured by Renesas Electronics Corporation, this component operates within the 3.14V to 3.47V supply voltage range and supports industrial temperature specifications from -40°C to 85°C. The ICS1893CFI is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

The 1893BFILF serves as a parametric equivalent to the ICS1893CFI based on the following critical substitution criteria:

• Identical protocol and function (Ethernet Physical Layer Controller)
• Matching interface architecture (Parallel)
• Identical standards compliance (10/100 Base-T/TX PHY)
• Identical voltage supply range (3.14V ~ 3.47V)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package and pinout (48-BSSOP, 0.295", 7.50mm Width)
• Same manufacturer (Renesas Electronics Corporation)
• Same series designation (PHYceiver™)

The primary distinction between these parts is product status and compliance certification, not electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 1893BFILF is the direct substitute for the ICS1893CFI in applications requiring active component availability. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

Selection between these parts should be based on the following factors:

• New Designs: Use 1893BFILF. The ICS1893CFI is obsolete and unsuitable for new development.
• Compliance Requirements: The 1893BFILF meets ROHS3 compliance, while the ICS1893CFI does not. Applications subject to RoHS regulations require the 1893BFILF.
• Inventory Status: The 1893BFILF maintains active production status with 728 units in stock, compared to 707 units of the obsolete ICS1893CFI.
• Moisture Handling: The 1893BFILF specifies MSL 3 (168 hours), requiring controlled storage conditions. The ICS1893CFI specifies MSL 1 (unlimited), indicating less stringent moisture sensitivity.

Frequently Asked Questions (FAQ)

Q: Can the 1893BFILF directly replace the ICS1893CFI in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 1893BFILF uses the same 48-BSSOP package, voltage supply range (3.14V ~ 3.47V), operating temperature range (-40°C ~ 85°C), and parallel interface architecture. No circuit modifications are required.

Q: Why is the ICS1893CFI marked as obsolete?

A: The ICS1893CFI has reached end-of-life status. Renesas Electronics Corporation has transitioned production to the 1893BFILF variant, which maintains identical functionality while meeting current RoHS3 compliance standards.

Q: What is the difference in Moisture Sensitivity Level between these parts?

A: The ICS1893CFI specifies MSL 1 (unlimited moisture exposure tolerance), while the 1893BFILF specifies MSL 3 (168-hour maximum exposure at specified humidity). This affects storage and handling procedures. MSL 3 components require desiccant packaging and controlled environmental conditions during storage and assembly.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both the ICS1893CFI and 1893BFILF operate across the -40°C to 85°C temperature range, meeting industrial specifications.

Q: What is the packaging difference between these parts?

A: The ICS1893CFI is supplied in standard packaging, while the 1893BFILF is supplied in tube packaging. Both use the identical 48-BSSOP physical form factor with 0.295" width and 7.50mm height.
