ZL40211LDF1 Equivalent & Substitute Parts

Part Overview

The ZL40211LDF1 is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Microchip Technology, designed for high-speed clock distribution applications. This 2:8 fanout buffer operates at frequencies up to 750 MHz and supports multiple input signal types including CML, HCSL, LVCMOS, LVDS, and LVPECL, with LVPECL output. The device is housed in a 32-VFQFN Exposed Pad package suitable for surface mount applications. As an active product with ROHS3 compliance and REACH unaffected status, substitute parts may be required due to inventory constraints, supply chain considerations, or specific application requirements where alternative Microchip fanout buffer models meet identical electrical and mechanical specifications.

• Voltage - Supply: Must be 2.375V ~ 3.465V
• Operating Temperature: Must be -40°C ~ 85°C
• Package / Case: Must be 32-VFQFN Exposed Pad
• Mounting Type: Must be Surface Mount
• RoHS Status: Must be ROHS3 Compliant
• MSL Rating: Must be 3 (168 Hours)

All substitute parts listed below meet these exact specifications and are manufactured by Microchip Technology.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ZL40211LDF1, ZL40210LDF1, and ZL40225LDF1—are active products with identical electrical specifications, mechanical packaging, and regulatory compliance status. Selection among these parts is based on availability and supply chain requirements rather than functional differences. Each part is ROHS3 compliant, REACH unaffected, and carries the same MSL rating of 3 (168 Hours), making them suitable for equivalent use in clock distribution applications requiring 2:8 fanout buffering at frequencies up to 750 MHz with multi-format input support and LVPECL output.

Frequently Asked Questions (FAQ)

Q: Can ZL40210LDF1 or ZL40225LDF1 be used as direct replacements for ZL40211LDF1?

A: Yes. All three parts are parametrically equivalent across all electrical and mechanical specifications, including input/output ratios, frequency ratings, signal types, supply voltage, operating temperature range, package type, and regulatory compliance. They are functionally interchangeable in applications designed for the ZL40211LDF1.

Q: Are there any differences in package or mounting between these parts?

A: No. All three parts use the identical 32-VFQFN Exposed Pad package with surface mount mounting type, ensuring compatibility with the same PCB layouts and assembly processes.

Q: What is the significance of the MSL rating for these parts?

A: The MSL (Moisture Sensitivity Level) rating of 3 (168 Hours) indicates the maximum time these components can be exposed to moisture at specified temperature and humidity conditions before soldering. All three parts share this rating, ensuring equivalent handling and storage requirements.

Q: Do all substitute parts meet the same regulatory standards?

A: Yes. ZL40210LDF1 and ZL40225LDF1 are both ROHS3 compliant and REACH unaffected, matching the compliance profile of the ZL40211LDF1.

Q: Are there inventory differences between these parts?

A: Inventory levels vary: ZL40211LDF1 has 720 pcs, ZL40210LDF1 has 5048 pcs, and ZL40225LDF1 has 4913 pcs available. Selection may be influenced by supply availability for your application timeline.
