Key Parameters

Substitute Part Grouping Explanation

Substitution for the ICS557GI-06 is determined by strict equivalence across the following critical parameters:

• Frequency specification (200MHz maximum)
• Input/Output signal types (HCSL and LVDS support)
• Input:Output ratio (2:4 configuration)
• Differential signal capability (both input and output)
• Supply voltage range (3.135V ~ 3.465V)
• Package type (20-TSSOP)
• Mounting technology (Surface Mount)
• Operating temperature range (-40°C ~ 85°C)

The substitute part 557GI-06LF meets all these electrical and mechanical parameters. The primary distinction between the main part and its substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 557GI-06LF is a direct functional equivalent to the ICS557GI-06 across all electrical and mechanical specifications. The substitute part offers two significant advantages:

1. Active product status: The 557GI-06LF is currently in active production, ensuring long-term availability and supply chain reliability.

2. Compliance certification: The 557GI-06LF is ROHS3 compliant, whereas the ICS557GI-06 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulations and environmental compliance requirements.

Both parts share identical REACH and ECCN classifications, indicating equivalent regulatory treatment for export and environmental purposes.

Frequently Asked Questions (FAQ)

Q: Can the 557GI-06LF replace the ICS557GI-06 in existing designs?

A: Yes. The 557GI-06LF is electrically and mechanically equivalent to the ICS557GI-06. All functional parameters, including frequency, signal types, voltage supply, temperature range, and package specifications, are identical.

Q: What is the difference between these two parts?

A: The primary differences are product status and RoHS compliance. The ICS557GI-06 is obsolete and RoHS non-compliant, while the 557GI-06LF is active production and ROHS3 compliant.

Q: Are there any package or pinout differences?

A: No. Both parts use the identical 20-TSSOP package with 0.173" width and 4.40mm dimensions. Pinout and mechanical compatibility are fully preserved.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical functional characteristics.

Q: What is the supply voltage tolerance for both parts?

A: Both the ICS557GI-06 and 557GI-06LF operate within a supply voltage range of 3.135V to 3.465V.

Q: Are both parts suitable for PCI Express applications?

A: Yes. Both parts are designed for PCI Express (PCIe) fanout buffer and distribution multiplexer applications with 200MHz maximum frequency support.
