Renesas ICS501MI Clock Generator - Equivalent & Substitute Parts

Part Overview

The Renesas ICS501MI is a Clock Generator IC operating at a maximum frequency of 140MHz, housed in an 8-SOIC surface mount package. This device features a Phase-Locked Loop (PLL) with multiplier capability, accepting clock or crystal inputs and delivering CMOS outputs. The ICS501MI is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS501MI is determined by strict equivalence across the following critical parameters:

• Frequency Rating: Maximum operating frequency of 140MHz
• Package Type: 8-SOIC (0.154", 3.90mm Width) surface mount configuration
• Functional Architecture: Clock Generator with PLL and multiplier capability
• Input/Output Specifications: Clock or Crystal input with CMOS output
• Electrical Specifications: Supply voltage range 3V ~ 5.25V and operating temperature range -40°C ~ 85°C
• Circuit Configuration: Single circuit (1:1 input-to-output ratio)

The substitute part 501MILF meets all these criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 501MILF serves as a direct functional equivalent to the ICS501MI across all electrical and mechanical parameters. The primary distinction lies in product lifecycle status and regulatory compliance:

• ICS501MI is classified as obsolete, limiting long-term availability and support.
• 501MILF maintains active product status, ensuring continued supply chain access and manufacturer support.

Additionally, the 501MILF achieves ROHS3 compliance, whereas the ICS501MI is non-compliant. For applications subject to RoHS directives or requiring future-proof component selection, the 501MILF is the appropriate choice. Both parts share identical electrical specifications, package geometry, and functional architecture, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 501MILF replace the ICS501MI in existing designs?

A: Yes. The 501MILF is electrically and mechanically equivalent to the ICS501MI. Both devices operate at identical frequency ratings, supply voltages, temperature ranges, and package configurations. Direct substitution is possible without modification to PCB layout or schematic design.

Q: What is the difference between ICS501MI and 501MILF?

A: The primary differences are product status and compliance. The ICS501MI is obsolete, while the 501MILF is active. The 501MILF achieves ROHS3 compliance, whereas the ICS501MI does not. All functional and electrical parameters remain identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The ICS501MI is supplied in standard packaging, while the 501MILF is supplied in tube packaging. This does not affect electrical performance or PCB compatibility.

Q: What supply voltage range do these clock generators support?

A: Both the ICS501MI and 501MILF operate across a supply voltage range of 3V to 5.25V, accommodating both 3.3V and 5V logic systems.

Q: What is the maximum operating frequency?

A: Both devices support a maximum frequency of 140MHz with PLL and multiplier functionality enabled.

Q: Are these parts suitable for industrial temperature applications?

A: Both the ICS501MI and 501MILF operate across the temperature range of -40°C to 85°C, covering commercial and industrial operating conditions.
