ICS511M Clock Generator IC Equivalent & Substitute Parts

Part Overview

The ICS511M is a Clock Generator IC manufactured by Renesas Electronics Corporation, designed for 200MHz clock generation applications. This device features a Phase-Locked Loop (PLL) architecture with programmable output ratios and operates across a 3.135V to 5.25V supply voltage range. The ICS511M is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS511M is determined by strict alignment across the following critical parameters:

• Frequency Specification: Maximum operating frequency of 200MHz
• PLL Architecture: Presence of integrated Phase-Locked Loop functionality
• Input/Output Configuration: Clock or Crystal input with CMOS output
• Circuit Count: Single circuit configuration
• Input:Output Ratio: 1:1 ratio specification
• Package Compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount package
• Voltage Supply Range: 3.135V ~ 5.25V operating range
• Operating Temperature Range: 0°C ~ 70°C

The 511MLF meets all electrical and mechanical substitution criteria for the ICS511M, with identical functional specifications and package form factor.

Parameter Comparison

Engineering Selection Recommendations

The 511MLF serves as a direct functional equivalent to the ICS511M across all electrical and mechanical parameters. Both devices share identical clock generation specifications, package form factor, and operating characteristics.

A key distinction exists in regulatory compliance: the ICS511M is RoHS non-compliant, while the 511MLF achieves ROHS3 compliance. For applications subject to RoHS directives or environmental regulations, the 511MLF provides compliance alignment while maintaining full functional equivalence.

Both parts carry REACH Unaffected status and identical ECCN and HTSUS classifications, supporting consistent supply chain documentation and regulatory reporting.

Frequently Asked Questions (FAQ)

Q: Can the 511MLF directly replace the ICS511M in existing designs?

A: Yes. The 511MLF matches all electrical specifications, frequency performance, and package dimensions of the ICS511M. Pin-for-pin compatibility and identical CMOS output characteristics support direct substitution at the component level.

Q: What is the significance of the RoHS compliance difference?

A: The ICS511M is RoHS non-compliant, while the 511MLF is ROHS3 compliant. For new designs or applications requiring RoHS certification, the 511MLF is the appropriate selection. For legacy system maintenance using existing ICS511M inventory, compliance requirements depend on application jurisdiction and customer specifications.

Q: Are the package dimensions identical?

A: Yes. Both the ICS511M and 511MLF use the 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints, land patterns, and assembly processes remain unchanged between the two parts.

Q: What is the difference between the base product numbers ICS511 and 511M?

A: The base product number identifies the core device family. The ICS511M and 511MLF represent different packaging and compliance variants of the same fundamental clock generator architecture, with the suffix indicating packaging type and regulatory status.

Q: Are there inventory considerations for substitution?

A: The ICS511M has 1843 pieces in stock, while the 511MLF has 1286 pieces available. Both are classified as new original stock. Procurement decisions should account for current inventory levels and project timeline requirements.
