Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS503MLFT is determined by strict equivalence across the following critical parameters:

• Frequency Specification: Maximum operating frequency of 160MHz
• Package Type: 8-SOIC (0.154", 3.90mm Width) surface mount configuration
• Functional Architecture: Single-circuit clock generator with PLL and 1:1 input-to-output ratio
• Input/Output Characteristics: Clock or crystal input with CMOS output
• Supply Voltage Range: Compatible operating voltage window
• Operating Temperature Range: 0°C to 70°C
• Mounting Technology: Surface mount only

The ICS501MLFT meets all substitution criteria as a direct equivalent, sharing identical functional specifications, package geometry, and electrical characteristics within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The ICS501MLFT is the direct substitute for the ICS503MLFT. Both devices are manufactured by Renesas Electronics Corporation and share identical functional and physical specifications across all critical parameters.

The primary distinction is product status: the ICS503MLFT is Obsolete, while the ICS501MLFT is Active. The ICS501MLFT offers superior long-term availability and supply chain stability. The ICS501MLFT is RoHS3 Compliant, providing enhanced environmental compliance for new designs and manufacturing processes.

The supply voltage range of the ICS501MLFT (3V ~ 5.25V) is slightly narrower than the ICS503MLFT (3V ~ 5.5V). Designs operating at the upper voltage boundary (5.25V to 5.5V) must verify compatibility with the substitute part's maximum supply specification.

Frequently Asked Questions (FAQ)

Q: Can the ICS501MLFT directly replace the ICS503MLFT in existing designs?

A: Yes. Both devices share identical package geometry (8-SOIC), frequency specification (160MHz), supply voltage compatibility (3V ~ 5.25V overlap), operating temperature range (0°C ~ 70°C), and functional architecture (single-circuit clock generator with PLL and 1:1 ratio). Pin-to-pin compatibility is maintained.

Q: What is the difference in supply voltage specifications?

A: The ICS503MLFT operates from 3V to 5.5V. The ICS501MLFT operates from 3V to 5.25V. If your design operates exclusively within the 3V to 5.25V window, no design modification is required. Designs requiring operation above 5.25V must retain the ICS503MLFT or verify alternative solutions.

Q: Why is the ICS501MLFT recommended over the ICS503MLFT?

A: The ICS501MLFT is Active status, ensuring ongoing availability and supply chain support. The ICS503MLFT is Obsolete and subject to discontinuation. The ICS501MLFT is RoHS3 Compliant, meeting current environmental and regulatory standards.

Q: Are there any package or mounting differences?

A: No. Both devices use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging. PCB footprints, solder reflow profiles, and assembly processes are interchangeable.

Q: What certifications apply to the substitute part?

A: The ICS501MLFT is RoHS3 Compliant and REACH Unaffected. Both devices carry ECCN EAR99 classification and HTSUS code 8542.39.0001.
