9FGL0241CKILF Equivalent & Substitute Parts

Part Overview

The 9FGL0241CKILF is a PCI Express (PCIe) Clock Generator IC manufactured by Renesas Electronics Corporation. This device generates clock signals for PCIe applications with a maximum frequency of 25MHz and operates from a 3.135V to 3.465V supply voltage. The component is housed in a 24-VFQFN (4x4) surface mount package with an exposed pad.

The 9FGL0241CKILF is classified as an obsolete product. Identification of equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity where original components are no longer readily available or where design requirements necessitate enhanced performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 9FGL0241CKILF is determined by compatibility across the following critical parameters:

Electrical Compatibility:

• Supply voltage range: 3.135V ~ 3.465V (must match)
• PLL functionality: Required (Yes)
• Input/Output ratio: 1:2 (must match)
• Operating temperature range: -40°C ~ 85°C (must match)

Mechanical Compatibility:

• Package type: 24-VFQFN Exposed Pad (must match)
• Mounting type: Surface Mount (must match)
• Form factor: 4x4 footprint (must match)

Regulatory & Environmental Compliance:

• RoHS3 Compliance: Required
• REACH Status: REACH Unaffected (must match)
• Moisture Sensitivity Level: 1 (Unlimited) (must match)

Functional Compatibility:

• Primary application: PCI Express (PCIe) Clock Generation
• Number of circuits: 1 (must match)

The 9FGL0241DKILF meets all substitution criteria. While this substitute part supports a higher maximum frequency (100MHz versus 25MHz), it maintains full compatibility with all electrical, mechanical, and regulatory parameters of the original component.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The 9FGL0241DKILF is a direct substitute for the 9FGL0241CKILF. Both components share identical electrical specifications, package geometry, and regulatory compliance certifications. The substitute part is manufactured by the same supplier (Renesas Electronics Corporation) and maintains full compatibility with existing PCB layouts and assembly processes.

Product Status Consideration:

The original 9FGL0241CKILF is classified as obsolete, while the 9FGL0241DKILF maintains active product status. Selection of the active substitute part ensures long-term availability and continued manufacturer support for new designs and legacy system maintenance.

Compliance Verification:

Both parts satisfy ROHS3 compliance requirements and maintain REACH Unaffected status. Moisture sensitivity level remains at MSL 1 (Unlimited) for both components, indicating no special handling or storage requirements beyond standard electronic component practices.

Frequency Capability:

The substitute part supports operation at frequencies up to 100MHz, compared to the original part's 25MHz maximum. This enhanced capability provides additional design flexibility for applications requiring higher clock frequencies while maintaining backward compatibility with existing 25MHz implementations.

Frequently Asked Questions (FAQ)

Q: Can the 9FGL0241DKILF be used as a direct replacement for the 9FGL0241CKILF in existing designs?

A: Yes. The 9FGL0241DKILF is electrically and mechanically compatible with the 9FGL0241CKILF. Both components operate from identical supply voltage ranges (3.135V ~ 3.465V), share the same 24-VFQFN package footprint, and maintain equivalent operating temperature specifications (-40°C ~ 85°C). No PCB modifications are required.

Q: What is the primary difference between these two parts?

A: The maximum frequency specification differs. The 9FGL0241CKILF operates at a maximum of 25MHz, while the 9FGL0241DKILF supports frequencies up to 100MHz. Both parts maintain identical supply voltage, package type, and regulatory compliance characteristics.

Q: Are there any packaging differences between the original and substitute parts?

A: Both components use the 24-VFQFN (4x4) surface mount package with an exposed pad. The physical footprint and pin configuration are identical, ensuring compatibility with existing PCB designs without layout modifications.

Q: Does the substitute part support the same input and output configurations?

A: The substitute part (9FGL0241DKILF) supports expanded input options (Clock and Crystal) compared to the original part (Clock only). Output configurations also differ: the original supports Clock output, while the substitute supports HCSL and LVCMOS outputs. Both parts maintain the 1:2 input-to-output ratio and PLL functionality.

Q: What is the regulatory compliance status of both parts?

A: Both the 9FGL0241CKILF and 9FGL0241DKILF are ROHS3 compliant and maintain REACH Unaffected status. Moisture sensitivity level is MSL 1 (Unlimited) for both components, indicating no special environmental handling requirements.

Q: Why is the original part classified as obsolete?

A: The 9FGL0241CKILF is listed as an obsolete product by the manufacturer. The 9FGL0241DKILF represents the active successor product, offering enhanced frequency capabilities while maintaining full backward compatibility with the original component specifications.

Q: Are there any supply voltage considerations when substituting these parts?

A: No. Both components operate within the identical supply voltage range of 3.135V ~ 3.465V. Existing power supply designs and voltage regulation circuits require no modification when implementing the substitute part.
