ICS570AI Equivalent & Substitute Parts

Part Overview

The ICS570AI is a Fanout Distribution and Spread Spectrum Clock Generator with Zero Delay Buffer functionality manufactured by Renesas Electronics Corporation. This 8-SOIC surface mount integrated circuit operates at a maximum frequency of 170MHz and is designed for clock distribution applications requiring a 1:2 input-to-output ratio. The ICS570AI is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS570AI is determined by strict equivalence across the following critical parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — ensures mechanical and electrical compatibility with existing PCB layouts
• Frequency - Max: 170MHz — maintains operational capability within the specified frequency range
• Input:Output Ratio: 1:2 — preserves the clock distribution architecture
• Voltage - Supply: 4.75V ~ 5.25V — ensures compatibility with existing power supply specifications
• Operating Temperature: -40°C ~ 85°C — maintains thermal operating range
• Output Type: CMOS — ensures signal compatibility with downstream circuitry
• PLL and Divider/Multiplier: Yes/Yes — confirms functional feature parity

The substitute part 570AILF meets all these criteria and is therefore electrically and mechanically equivalent to the ICS570AI.

Parameter Comparison

Engineering Selection Recommendations

The 570AILF is a direct functional equivalent to the ICS570AI. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications across all critical parameters including frequency, voltage supply, operating temperature range, package type, and functional architecture.

A key distinction exists in regulatory compliance: the ICS570AI is RoHS non-compliant, while the 570AILF is ROHS3 compliant. For applications subject to RoHS directives or environmental regulations, the 570AILF is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

The primary difference between these parts is packaging format: the ICS570AI is supplied in standard packaging, while the 570AILF is supplied in tube packaging. This distinction affects handling and storage but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 570AILF be used as a direct replacement for the ICS570AI?

A: Yes. The 570AILF is electrically and mechanically equivalent to the ICS570AI. All critical parameters including frequency, voltage supply, operating temperature, package type, and functional features are identical.

Q: What is the difference between the ICS570AI and 570AILF?

A: The primary differences are packaging format (tube versus standard) and RoHS compliance status. The 570AILF is ROHS3 compliant, while the ICS570AI is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the 570AILF for the ICS570AI?

A: No compatibility concerns exist. Both parts use the same 8-SOIC package footprint, operate at identical voltage and frequency specifications, and provide the same functional output characteristics. PCB layout and circuit design require no modification.

Q: Why is the ICS570AI marked as obsolete?

A: The ICS570AI is classified as obsolete by the manufacturer. The 570AILF serves as the current equivalent part for ongoing procurement and system support.

Q: Does the tube packaging of the 570AILF affect its electrical performance?

A: No. Packaging format does not affect electrical performance or functional characteristics. Tube packaging is a handling and storage format only.

Q: Are both parts subject to the same environmental regulations?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The 570AILF offers improved compliance through ROHS3 certification, which may be required for certain applications or markets.
