Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS1893BF is determined by the following critical parameters:

• Protocol: Ethernet
• Function: Physical Layer Controller
• Interface Type: Parallel
• Standards: 10/100 Base-T/TX PHY
• Voltage - Supply: 3.14V ~ 3.47V
• Operating Temperature: 0°C ~ 70°C
• Package / Case: 48-BSSOP (0.295", 7.50mm Width)
• Supplier Device Package: 48-SSOP

The substitute part 1893CFLF meets all electrical and mechanical parameters required for direct substitution. Both components share identical protocol specifications, functional classification, interface architecture, and physical packaging dimensions. Supply voltage ranges and operating temperature specifications are equivalent across both parts.

Parameter Comparison

Engineering Selection Recommendations

The 1893CFLF is a direct parametric equivalent to the ICS1893BF for applications requiring 10/100 Base-T/TX PHY Ethernet physical layer control with parallel interface architecture. Both components are manufactured by Renesas Electronics Corporation and share identical electrical specifications and physical packaging.

The 1893CFLF offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the 1893CFLF meets ROHS3 compliance requirements, whereas the ICS1893BF is RoHS non-compliant. The moisture sensitivity level differs between the two parts (MSL 3 versus MSL 1), which may affect storage and handling procedures depending on application environment requirements.

Selection between these parts should be based on supply chain availability, compliance requirements for the target application, and storage condition capabilities.

Frequently Asked Questions (FAQ)

Q: Can the 1893CFLF directly replace the ICS1893BF in existing designs?

A: Yes. Both components share identical electrical parameters, functional specifications, and physical packaging. No circuit modifications are required for substitution.

Q: What is the difference in product status between these parts?

A: The ICS1893BF is classified as obsolete and no longer in production. The 1893CFLF is an active product with ongoing manufacturing support and availability.

Q: How do the RoHS compliance statuses differ?

A: The ICS1893BF is RoHS non-compliant. The 1893CFLF is ROHS3 compliant. Applications subject to RoHS regulatory requirements should use the 1893CFLF.

Q: What does the difference in Moisture Sensitivity Level (MSL) mean?

A: The ICS1893BF has MSL 1 (unlimited moisture exposure tolerance). The 1893CFLF has MSL 3 (168-hour moisture exposure limit). The 1893CFLF requires more controlled storage conditions to prevent moisture absorption during handling and assembly.

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both components operate at 3.14V to 3.47V supply voltage and 0°C to 70°C operating temperature range.

Q: Is the physical packaging identical?

A: Yes. Both components use 48-BSSOP (0.295", 7.50mm Width) package configuration with 48-SSOP supplier device package designation. PCB footprints are identical.
