ICS501M Clock Generator IC Equivalent & Substitute Parts

Part Overview

The ICS501M is a Clock Generator IC manufactured by Renesas Electronics Corporation, designed for 160MHz clock generation applications. It features a Phase-Locked Loop (PLL) with programmable output ratios and operates across a 3V to 5.25V supply voltage range in an 8-SOIC surface mount package.

The ICS501M is classified as obsolete. Locating equivalent substitute parts is necessary to support legacy system maintenance, design updates, and continued component availability for production environments where this device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS501M is determined by strict equivalence across the following critical parameters:

• Maximum frequency specification: 160MHz
• PLL functionality: Present
• Input signal types: Clock and Crystal support
• Output signal type: CMOS
• Supply voltage range: 3V ~ 5.25V
• Operating temperature range: 0°C ~ 70°C
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Number of independent circuits: 1
• Input-to-output ratio: 1:1

The 501MLF meets all these criteria and is therefore a direct functional equivalent to the ICS501M.

Parameter Comparison

Engineering Selection Recommendations

The 501MLF is the direct substitute for the ICS501M. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The ICS501M is obsolete, while the 501MLF maintains active production status. The 501MLF additionally meets ROHS3 compliance requirements, whereas the ICS501M is non-compliant. For new designs or system updates, the 501MLF is the appropriate selection. For legacy system support where the ICS501M is currently specified, the 501MLF provides full functional equivalence with improved regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the 501MLF be used as a direct replacement for the ICS501M in existing designs?

A: Yes. The 501MLF is electrically and mechanically equivalent to the ICS501M. Both devices operate at identical frequency specifications, supply voltage ranges, and temperature ranges. The 8-SOIC package dimensions are identical, permitting direct PCB substitution without layout modifications.

Q: What is the difference between the ICS501M and 501MLF?

A: The devices are functionally identical. The ICS501M is classified as obsolete, while the 501MLF is in active production. The 501MLF meets ROHS3 compliance standards; the ICS501M does not. Both parts are manufactured by Renesas Electronics Corporation and share the same base product number (501M).

Q: Are there any compatibility concerns when substituting the 501MLF for the ICS501M?

A: No compatibility concerns exist. The 501MLF maintains the same pinout, package footprint, electrical characteristics, and functional behavior as the ICS501M. No circuit modifications or firmware updates are required.

Q: What packaging options are available for these parts?

A: Both the ICS501M and 501MLF are supplied in 8-SOIC (0.154", 3.90mm Width) surface mount packages. The ICS501M is available in standard packaging; the 501MLF is supplied in tube packaging.

Q: Are these parts suitable for new product designs?

A: The 501MLF is suitable for new designs. It is in active production status and meets current RoHS3 compliance requirements. The ICS501M, being obsolete, is not recommended for new designs.
