PI6C557-06LEX Equivalent & Substitute Parts

Part Overview

The PI6C557-06LEX is a PCI Express (PCIe) clock generator IC manufactured by Diodes Incorporated, designed to generate 200MHz clock signals with 1 output in a 20-TSSOP package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. Substitute parts must maintain electrical compatibility across input/output signal types, frequency specifications, and supply voltage parameters while accommodating potential package variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI6C557-06LEX is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Maximum frequency: 200MHz
• Input signal type: HCSL (differential)
• Output signal type: HCSL (differential)
• Input:Output ratio: 2:4
• Supply voltage range: 3.135V ~ 3.465V
• Number of circuits: 1
• Mounting type: Surface Mount
• RoHS3 compliance

Allowable Variations:

• Package type: Alternative surface-mount packages (20-TSSOP or 24-VFQFN) are acceptable provided pinout compatibility is verified
• Operating temperature range: Extended ranges are acceptable for applications not requiring the original 0°C ~ 70°C specification
• Product status: Active parts are preferred over obsolete alternatives

Parameter Comparison

Engineering Selection Recommendations

5V41067APGG (Renesas Electronics Corporation): This substitute maintains identical package geometry (20-TSSOP), electrical specifications, and operating temperature range as the PI6C557-06LEX. The part is ROHS3 compliant and supports both HCSL and LVDS output options, providing additional flexibility. However, this part is also classified as obsolete, limiting its long-term availability for production applications.

9DML0441AKILF (Renesas Electronics Corporation): This substitute provides active product status, ensuring ongoing availability and manufacturing support. It maintains all critical electrical parameters including 200MHz frequency, 2:4 input:output ratio, HCSL differential input/output, and 3.135V ~ 3.465V supply voltage. The extended operating temperature range (-40°C ~ 85°C) exceeds the original specification. The package differs (24-VFQFN versus 20-TSSOP), requiring PCB layout and pinout verification before implementation. ROHS3 compliance is maintained.

For new designs and long-term production support, 9DML0441AKILF is the preferred selection due to active product status. For direct form-fit-function replacement in existing designs, 5V41067APGG maintains identical packaging.

Frequently Asked Questions (FAQ)

Q: Can 5V41067APGG be used as a direct replacement for PI6C557-06LEX? A: Yes. Both parts share identical package geometry (20-TSSOP), electrical specifications, supply voltage range (3.135V ~ 3.465V), maximum frequency (200MHz), and operating temperature range (0°C ~ 70°C). No PCB modifications are required.

Q: What is the primary difference between 5V41067APGG and 9DML0441AKILF? A: The 5V41067APGG maintains the original 20-TSSOP package and obsolete product status. The 9DML0441AKILF uses a 24-VFQFN package, offers active product status, and supports an extended operating temperature range (-40°C ~ 85°C). Both maintain identical electrical performance at 200MHz with 2:4 input:output ratio.

Q: Is the 24-VFQFN package of 9DML0441AKILF compatible with existing 20-TSSOP PCB layouts? A: No. The 24-VFQFN package has different physical dimensions and pinout. PCB redesign and pinout verification are required before implementation.

Q: Do all substitute parts maintain ROHS3 compliance? A: Yes. Both 5V41067APGG and 9DML0441AKILF are ROHS3 compliant, matching the original PI6C557-06LEX specification.

Q: Which substitute is recommended for new product designs? A: 9DML0441AKILF is recommended for new designs due to active product status, ensuring long-term availability and manufacturing support. The extended operating temperature range provides additional design margin for industrial applications.

Q: Are there any output signal differences between the substitutes? A: The 5V41067APGG supports both HCSL and LVDS output options, while 9DML0441AKILF supports HCSL output only. Both maintain HCSL differential output compatibility with the original PI6C557-06LEX.
