Key Parameters

Substitute Part Grouping Explanation

Substitution of the MK5811CMILF is determined by the following critical parameters:

• Functional Type: Clock Generator with PLL capability
• Output Standard: LVCMOS logic levels
• Input Configuration: Crystal or clock input support
• Operating Temperature Range: -40°C to 85°C
• Compliance: ROHS3 and REACH compliance status
• Moisture Sensitivity: MSL 1 rating

The substitute part 5X2503-000NDGI is identified as a manufacturer-recommended equivalent. However, this substitute exhibits significant parameter variations that must be evaluated for application compatibility, including differences in frequency range, supply voltage, number of output circuits, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

The 5X2503-000NDGI is listed as the manufacturer-recommended substitute for the MK5811CMILF. Both components share identical operating temperature ranges (-40°C to 85°C), RoHS3 compliance, and MSL 1 ratings, establishing baseline compatibility for environmental and regulatory requirements.

Critical differences exist in frequency specification, supply voltage, and package geometry. The MK5811CMILF operates at 32MHz with 3V to 3.63V supply, while the 5X2503-000NDGI operates at 32.768kHz with 1.71V to 1.89V supply. The 5X2503-000NDGI provides three output circuits compared to the single circuit of the MK5811CMILF, and uses a different package form factor (12-UFDFN versus 8-SOIC).

Selection of the 5X2503-000NDGI as a substitute requires verification that the application can accommodate the lower frequency output, reduced supply voltage range, and alternative package footprint. The Active product status of the 5X2503-000NDGI ensures long-term availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the 5X2503-000NDGI directly replace the MK5811CMILF in existing designs?

A: Direct replacement is not possible without design modifications. The frequency specifications differ significantly (32MHz versus 32.768kHz), and the supply voltage ranges are incompatible (3V-3.63V versus 1.71V-1.89V). PCB layout changes are required due to package differences (8-SOIC versus 12-UFDFN).

Q: What are the key compatibility criteria for clock generator substitution?

A: Substitution requires matching or compatible frequency output, overlapping supply voltage ranges, compatible output logic standards (LVCMOS in this case), and identical or superior operating temperature ranges. Package footprint and pin configuration must also be evaluated for PCB integration.

Q: Why is the MK5811CMILF classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The 5X2503-000NDGI, with Active status, represents the current manufacturing alternative from Renesas Electronics Corporation.

Q: Are there compliance considerations when substituting these parts?

A: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution in compliant applications. MSL 1 ratings on both components indicate unlimited shelf life under controlled storage conditions.

Q: How do the output circuit counts affect substitution?

A: The MK5811CMILF provides one output circuit, while the 5X2503-000NDGI provides three. Applications requiring single clock outputs may not utilize all available circuits on the substitute part, but this does not prevent substitution if frequency and voltage requirements are met.
