Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS511MI is determined by strict equivalence across the following critical parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — physical and electrical compatibility
• Frequency - Max: 160MHz — functional performance requirement
• Voltage - Supply: 3.135V ~ 5.25V — power supply compatibility
• Operating Temperature: -40°C ~ 85°C — thermal operating range
• Output Type: CMOS — signal interface compatibility
• PLL Capability: Yes — functional architecture requirement
• Input Type: Clock, Crystal — input signal compatibility

The direct substitute 511MILF maintains identical electrical and mechanical specifications while offering improved RoHS3 compliance status. This part is functionally interchangeable at the circuit level and pin level.

Parameter Comparison

Engineering Selection Recommendations

The 511MILF serves as the primary direct substitute for the ICS511MI. Both parts are classified as obsolete; however, the 511MILF offers RoHS3 compliance, which may be required for new designs or systems subject to environmental regulations. The electrical and mechanical specifications are identical, ensuring pin-for-pin and functional compatibility.

Selection between ICS511MI and 511MILF should be based on:

• Regulatory Requirements: If RoHS3 compliance is mandated, 511MILF is the appropriate choice
• Inventory Status: ICS511MI has 2360 units available; 511MILF has 1495 units available
• Packaging Format: ICS511MI is supplied in standard packaging; 511MILF is supplied in tube packaging

Both parts maintain identical electrical performance across the specified frequency range, supply voltage, and operating temperature parameters.

Frequently Asked Questions (FAQ)

Q: Can 511MILF be used as a direct replacement for ICS511MI in existing designs?

A: Yes. The 511MILF is electrically and mechanically equivalent to the ICS511MI. Pin configuration, package dimensions, and electrical specifications are identical. No circuit modifications are required.

Q: What is the primary difference between ICS511MI and 511MILF?

A: The primary difference is RoHS compliance status. The 511MILF is RoHS3 compliant, while the ICS511MI is RoHS non-compliant. All electrical and functional parameters are identical.

Q: Are there any packaging considerations when substituting these parts?

A: The ICS511MI and 511MILF use identical 8-SOIC (0.154", 3.90mm Width) packages. The 511MILF is supplied in tube packaging, while the ICS511MI uses standard packaging. This does not affect electrical compatibility or PCB assembly procedures.

Q: What supply voltage range is supported by both parts?

A: Both the ICS511MI and 511MILF operate across a supply voltage range of 3.135V to 5.25V, ensuring compatibility with standard 3.3V and 5V logic systems.

Q: What is the maximum frequency output for these clock generators?

A: Both parts support a maximum frequency of 160MHz with a 1:1 input-to-output ratio and integrated PLL functionality.

Q: Are these parts suitable for new designs?

A: Both the ICS511MI and 511MILF are classified as obsolete. For new designs, evaluation of alternative active clock generator products from Renesas Electronics Corporation or other manufacturers is recommended based on specific application requirements.
