PI6C22409LIEX Equivalent & Substitute Parts

Part Overview

The PI6C22409LIEX is a zero-delay clock buffer IC manufactured by Diodes Incorporated, designed for high-speed clock distribution applications. This 16-TSSOP surface-mount device operates at frequencies up to 220MHz with a 1:9 input-to-output ratio and features PLL with bypass capability. The part is currently classified as obsolete, making identification of functionally equivalent substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI6C22409LIEX is determined by strict equivalence across the following critical parameters:

• Maximum Frequency: 220MHz (exact match required)
• Input-to-Output Ratio: 1:9 (exact match required)
• Supply Voltage Range: Minimum 2.3V to 3.6V maximum (substitute range must encompass or be compatible with 2.375V ~ 3.6V)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 16-TSSOP (0.173", 4.40mm Width) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• PLL Configuration: Yes with Bypass (exact match required)
• Circuit Count: 1 (exact match required)

The SL23EP09ZI-1T from Skyworks Solutions Inc. meets all substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

The SL23EP09ZI-1T is a direct functional equivalent for the PI6C22409LIEX. Both devices are RoHS3 compliant and share identical ECCN and HTSUS classifications, ensuring regulatory consistency. The primary distinction is product status: the PI6C22409LIEX is obsolete, while the SL23EP09ZI-1T is active and currently in production.

The SL23EP09ZI-1T features a slightly lower minimum supply voltage (2.3V versus 2.375V), which provides enhanced compatibility with lower-voltage system designs while maintaining the same maximum operating voltage. The substitute part carries a higher Moisture Sensitivity Level (MSL 2 versus MSL 1), requiring standard moisture control during storage and handling per IPC standards.

For new designs and ongoing production support, the SL23EP09ZI-1T is the appropriate selection due to its active product status and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the SL23EP09ZI-1T be used as a direct replacement for the PI6C22409LIEX in existing designs?

A: Yes. Both devices share identical electrical specifications across frequency, input-to-output ratio, operating temperature, and supply voltage compatibility. The 16-TSSOP package dimensions are identical, enabling direct PCB substitution without layout modifications.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The PI6C22409LIEX carries MSL 1 (unlimited shelf life), while the SL23EP09ZI-1T carries MSL 2 (1-year shelf life). MSL 2 requires standard moisture control during storage and handling. Both levels are standard for surface-mount ICs and do not affect functional performance when proper handling procedures are followed.

Q: Are there any supply voltage differences that affect system design?

A: The SL23EP09ZI-1T operates from 2.3V minimum, compared to 2.375V for the PI6C22409LIEX. This 75mV difference is negligible for most applications and actually provides improved compatibility with lower-voltage systems. Both devices operate identically at the upper limit of 3.6V.

Q: Why is the PI6C22409LIEX classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SL23EP09ZI-1T remains in active production, making it the recommended choice for new designs and long-term supply continuity.

Q: Are both parts RoHS compliant?

A: Yes. Both the PI6C22409LIEX and SL23EP09ZI-1T are RoHS3 compliant, meeting current environmental and regulatory requirements.
