ICS503MLF Clock Generator IC Equivalent & Substitute Parts

Part Overview

The ICS503MLF 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 5.5V supply range in an 8-SOIC surface mount package. The ICS503MLF is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS503MLF is determined by strict alignment of the following electrical and mechanical parameters:

• Maximum frequency capability: 160MHz
• PLL functionality: Required
• Input type: Clock or Crystal
• Output type: CMOS
• Input:Output ratio: 1:1
• Supply voltage range: Minimum 3V, maximum not exceeding 5.5V
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Number of circuits: 1

The ICS501MLF meets all substitution criteria and is classified as an active product, providing design continuity for applications currently using the obsolete ICS503MLF.

Parameter Comparison

Engineering Selection Recommendations

The ICS501MLF is the direct substitute for the obsolete ICS503MLF. Both parts share identical functional specifications across all critical parameters: 160MHz maximum frequency, PLL architecture, 1:1 input:output ratio, CMOS output, and 8-SOIC package configuration.

The ICS501MLF offers the advantage of active product status, ensuring ongoing availability and manufacturing support. The supply voltage range of the ICS501MLF (3V ~ 5.25V) is contained within the ICS503MLF specification (3V ~ 5.5V), confirming electrical compatibility in all standard applications. The ICS501MLF carries ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Both parts maintain identical moisture sensitivity levels and are subject to the same regulatory classifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can the ICS501MLF directly replace the ICS503MLF in existing designs?

A: Yes. The ICS501MLF meets all electrical and mechanical substitution criteria. Both parts operate at 160MHz maximum frequency, feature identical PLL functionality, accept Clock or Crystal inputs, and are packaged in the same 8-SOIC form factor. The supply voltage range of the ICS501MLF is fully compatible with designs specified for the ICS503MLF.

Q: What is the primary difference between these parts?

A: The ICS503MLF is classified as obsolete, while the ICS501MLF is an active product. The ICS501MLF also carries ROHS3 compliance certification. Functionally and electrically, the parts are equivalent.

Q: Are there any supply voltage considerations when substituting?

A: The ICS501MLF operates across 3V to 5.25V, which is within the ICS503MLF specification of 3V to 5.5V. Applications designed for the ICS503MLF will operate correctly with the ICS501MLF across standard supply ranges.

Q: Is the 8-SOIC package identical for both parts?

A: Yes. Both the ICS503MLF and ICS501MLF use the 8-SOIC (0.154", 3.90mm Width) package with surface mount mounting type. PCB layouts and footprints are interchangeable.

Q: What certifications apply to the ICS501MLF?

A: The ICS501MLF is ROHS3 compliant and carries REACH Unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
