PI6C557-05BLEX Equivalent & Substitute Parts

Part Overview

The PI6C557-05BLEX is an active clock generator IC manufactured by Diodes Incorporated, designed for Ethernet and PCI Express (PCIe) applications. This 20-TSSOP surface mount device generates up to 200MHz output frequencies with HCSL and LVDS output options, operating from a 3.135V to 3.465V supply. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when they maintain electrical compatibility across critical parameters including frequency range, voltage supply specifications, output types, and physical packaging, while meeting equivalent compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI6C557-05BLEX are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

• Maximum frequency capability of 200MHz or greater
• Supply voltage range of 3.135V to 3.465V
• Output configuration supporting HCSL and LVDS formats
• Input compatibility with Clock or Crystal sources
• 1:4 input-to-output ratio
• Identical 20-TSSOP package footprint and dimensions
• Operating temperature range of -40°C to 85°C minimum
• Surface mount technology
• PLL functionality present
• ROHS3 compliance and MSL 1 rating

The 5V41236PGGI from Renesas Electronics Corporation meets all these parameters and qualifies as a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the PI6C557-05BLEX and 5V41236PGGI are active production devices with ROHS3 compliance and identical MSL ratings. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (Tape & Reel versus Tube)
• Manufacturer qualification requirements within your supply chain
• Cost considerations

Both devices meet all electrical specifications for Ethernet and PCI Express (PCIe) clock generation applications. The identical package footprint, voltage specifications, frequency range, and temperature operating range ensure direct PCB-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 5V41236PGGI replace the PI6C557-05BLEX in existing designs?

A: Yes. Both devices share identical electrical specifications (200MHz maximum frequency, 3.135V–3.465V supply voltage, 1:4 input-to-output ratio), output types (HCSL and LVDS), and package dimensions (20-TSSOP). No PCB redesign is required.

Q: Are there differences in input compatibility?

A: The PI6C557-05BLEX accepts HCSL or Crystal inputs, while the 5V41236PGGI accepts Clock or Crystal inputs. Both support Crystal input, which is the primary configuration for most applications. Verify your specific input signal type before substitution.

Q: What is the significance of the 20-TSSOP package match?

A: Identical package dimensions (0.173" width, 4.40mm) ensure the substitute part fits the same PCB footprint without layout modifications. Both devices are surface mount components with matching pin configurations for this package type.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PI6C557-05BLEX and 5V41236PGGI are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the operating temperature range for both devices?

A: Both devices operate across -40°C to 85°C, meeting industrial and commercial temperature specifications for Ethernet and PCIe applications.

Q: Are there packaging format differences?

A: The PI6C557-05BLEX is supplied in Tape & Reel (TR) format, while the 5V41236PGGI is supplied in Tube format. Both formats contain the same component; packaging choice depends on assembly line requirements and inventory management preferences.
