PI6C557-05LE Equivalent & Substitute Parts

Part Overview

The PI6C557-05LE is an Ethernet and PCI Express (PCIe) clock generator IC manufactured by Diodes Incorporated. This device generates a 200MHz output from a single circuit with HCSL and LVDS output options, operating from a 3.135V to 3.465V supply. The part is currently listed as obsolete, making substitute components necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI6C557-05LE is determined by strict equivalence across the following parameters:

• Maximum frequency: 200MHz
• Output configuration: HCSL and LVDS support
• Input configuration: HCSL or Crystal input capability
• Circuit count: Single circuit (1:4 ratio)
• Supply voltage range: 3.135V ~ 3.465V
• Operating temperature range: -40°C ~ 85°C
• Package type: 20-TSSOP surface mount
• Compliance: ROHS3 and REACH requirements

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

PI6C557-05LEX is the direct successor from Diodes Incorporated with active product status, making it the primary substitute for obsolete PI6C557-05LE applications. Both parts share identical electrical and mechanical specifications with equivalent compliance certifications.

The Renesas Electronics Corporation alternatives, 5V41236PGGI8 and 5V41236PGGI, provide functionally equivalent substitution with active product status. The 5V41236PGGI8 variant offers higher inventory availability (18,100 pcs) compared to 5V41236PGGI (1,273 pcs). Both Renesas parts maintain all critical electrical parameters and compliance requirements.

Selection between Diodes and Renesas alternatives depends on supply chain availability, procurement lead times, and existing vendor relationships, as all parts meet identical functional and compliance criteria.

Frequently Asked Questions (FAQ)

Q: Can PI6C557-05LEX directly replace PI6C557-05LE in existing designs?

A: Yes. PI6C557-05LEX maintains identical electrical specifications, supply voltage range, frequency output, input/output signal types, operating temperature range, and 20-TSSOP package configuration. No design modifications are required.

Q: What is the difference between PI6C557-05LEX and the Renesas 5V41236PGGI variants?

A: Both manufacturers' parts are electrically equivalent across all specified parameters: 200MHz maximum frequency, 3.135V to 3.465V supply voltage, 1:4 input-to-output ratio, HCSL and LVDS output support, and 20-TSSOP packaging. The primary difference is manufacturer origin and packaging format (Diodes Incorporated offers Cut Tape & Digi-Reel; Renesas offers Tube packaging for 5V41236PGGI).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PI6C557-05LEX, 5V41236PGGI8, and 5V41236PGGI are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status.

Q: Does the input signal type difference between HCSL/Crystal (Diodes) and Clock/Crystal (Renesas) affect compatibility?

A: No. Both input configurations support the required clock generation functionality for Ethernet and PCI Express applications. The electrical performance and output characteristics remain equivalent.

Q: Which substitute part offers the best procurement availability?

A: 5V41236PGGI8 (Renesas) has the highest inventory at 18,100 pcs, followed by PI6C557-05LEX (Diodes) at 59,400 pcs. Both provide substantial stock for immediate procurement.
