PI6C4921506LIEX Equivalent & Substitute Parts

Part Overview

The PI6C4921506LIEX is an active Clock Fanout Buffer (Distribution) IC manufactured by Diodes Incorporated. This 1:6 clock distribution device operates at a maximum frequency of 1.5 GHz and is designed for applications requiring differential clock signal distribution in high-speed digital systems. The part is currently in active production status with 9200 units available in inventory.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of this product category, specifically matching the 1:6 fanout ratio, 24-TSSOP package form factor, and compatible voltage supply specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI6C4921506LIEX is determined by strict adherence to the following critical parameters:

Primary Substitution Criteria:

• Fanout ratio of 1:6 (one input, six outputs)
• 24-TSSOP package form factor with 0.173" width and 4.40mm body width
• Differential input and output capability (Yes/Yes)
• LVDS output type
• Supply voltage range of 2.375V ~ 3.465V
• Surface mount mounting type
• Operating temperature range of -40°C ~ 85°C

The substitute part 854S006AGILF meets all primary substitution criteria. While this part features a higher maximum frequency specification (1.7 GHz versus 1.5 GHz), it maintains full compatibility with the electrical and mechanical interface requirements of the PI6C4921506LIEX. The substitute accepts a broader range of input signal types (HCSL, LVDS, LVHSTL, LVPECL, SSTL) compared to the main part (LVCMOS, LVTTL), providing enhanced input flexibility without compromising output performance.

Parameter Comparison

Engineering Selection Recommendations

Both the PI6C4921506LIEX and 854S006AGILF are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for current design implementations. The selection between these parts should be based on the following factors:

PI6C4921506LIEX is the primary choice when the design operates at or below 1.5 GHz and when input signals are limited to LVCMOS or LVTTL logic levels. This part is available in Tape & Reel packaging, which is standard for high-volume manufacturing environments.

854S006AGILF is the appropriate substitute when higher frequency headroom is required (up to 1.7 GHz) or when the design may receive input signals from multiple logic families including HCSL, LVDS, LVHSTL, LVPECL, or SSTL. This part is supplied in Tube packaging. Both parts share identical package geometry, supply voltage specifications, and operating temperature ranges, ensuring direct mechanical and electrical compatibility at the board level.

Frequently Asked Questions (FAQ)

Q: Can the 854S006AGILF directly replace the PI6C4921506LIEX in an existing design?

A: Yes. Both parts feature identical 24-TSSOP package dimensions, supply voltage ranges (2.375V ~ 3.465V), operating temperature specifications (-40°C ~ 85°C), and output type (LVDS). The 1:6 fanout ratio and differential input/output configuration are identical. The substitute part's higher frequency rating (1.7 GHz) and broader input compatibility do not create incompatibility with designs specified for the main part.

Q: What is the difference in packaging between these two parts?

A: The PI6C4921506LIEX is supplied in Tape & Reel (TR) format, while the 854S006AGILF is supplied in Tube packaging. Both packaging formats contain the same component in the same 24-TSSOP case. Tape & Reel is typically used for automated pick-and-place assembly, while Tube packaging is used for manual handling or lower-volume applications. This difference does not affect component performance or compatibility.

Q: Why does the 854S006AGILF accept more input signal types than the PI6C4921506LIEX?

A: The 854S006AGILF is designed to accept HCSL, LVDS, LVHSTL, LVPECL, and SSTL input signals, while the PI6C4921506LIEX accepts only LVCMOS and LVTTL. This expanded input compatibility is a design feature of the Renesas part and does not affect its ability to function with LVCMOS or LVTTL inputs. Designs using only LVCMOS or LVTTL inputs will operate identically with either part.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, carry MSL rating 1 (Unlimited), and are REACH unaffected. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001. No compliance or certification differences exist between the two parts.

Q: What is the significance of the 1:6 fanout ratio?

A: The 1:6 ratio indicates that one input clock signal is distributed to six output channels. This is a fixed architectural feature of both parts and cannot be changed. Any substitute part must maintain this same 1:6 configuration to ensure compatibility with the circuit design.
