Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS1893CKI-40LF is determined by strict alignment across the following critical parameters:

• Ethernet protocol and 10/100 Base-T/TX PHY standards compliance
• Parallel interface architecture
• Voltage supply range: 3.14V ~ 3.47V
• Operating temperature range: -40°C ~ 85°C
• Physical Layer Controller function classification
• 40-pin QFN package format with exposed pad (6x6 footprint)
• Renesas Electronics Corporation PHYceiver™ series membership
• Moisture Sensitivity Level 3 rating

The substitute part 1894KI-40LF meets all specified electrical and mechanical parameters, with the primary distinction being active product status versus the obsolete classification of the original part.

Parameter Comparison

Engineering Selection Recommendations

The 1894KI-40LF serves as the direct functional equivalent for the obsolete ICS1893CKI-40LF. Selection of the substitute part is justified by:

• Identical electrical specifications across voltage supply and operating temperature ranges
• Matching protocol, standards, and interface architecture
• Equivalent package footprint and pin configuration (40-pin QFN with exposed pad, 6x6mm)
• Active product status ensuring ongoing availability and manufacturing support
• Identical regulatory compliance: REACH Unaffected, EAR99 classification, and HTSUS coding
• Equivalent moisture sensitivity rating for assembly and storage requirements

The 1894KI-40LF is suitable for direct substitution in applications currently utilizing the ICS1893CKI-40LF, with no circuit redesign required.

Frequently Asked Questions (FAQ)

Q: Can the 1894KI-40LF replace the ICS1893CKI-40LF in existing designs?

A: Yes. The 1894KI-40LF is electrically and mechanically equivalent across all specified parameters. No circuit modifications are necessary for direct substitution.

Q: What is the primary difference between these two parts?

A: The ICS1893CKI-40LF is classified as obsolete, while the 1894KI-40LF maintains active product status. Both parts share identical electrical specifications and package configurations.

Q: Are the package designations interchangeable?

A: Both parts use 40-pin QFN packages with exposed pads in 6x6mm footprints. The supplier device package designations (40-VFQFPN versus 40-QFN-EP) refer to the same physical format and are footprint-compatible.

Q: What are the critical parameters for substitution eligibility?

A: Substitution is determined by matching Ethernet protocol compliance, 10/100 Base-T/TX PHY standards, parallel interface architecture, 3.14V to 3.47V supply voltage range, -40°C to 85°C operating temperature, and 40-pin QFN package format with exposed pad.

Q: Are there any compliance or regulatory differences?

A: No. Both parts carry identical REACH, ECCN, and HTSUS classifications. Moisture sensitivity levels are equivalent at MSL 3 (168 hours).
