Substitute Part Grouping Explanation

The ZL40250LDG1 qualifies as a parametric equivalent based on the following matching criteria:

Matching Parameters:

• Manufacturer: Microchip Technology
• Series: SmartBuffer™
• Type: Fanout Buffer (Distribution), Divider, Multiplexer
• Differential Input/Output: Yes/Yes
• Input Formats: CMOS, Crystal
• Output Formats: CML, CMOS, HCSL, HSTL, LVDS, LVPECL, SSTL
• Frequency - Max: 1.035 GHz
• Voltage - Supply: 1.71V ~ 3.465V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 56-VFQFN Exposed Pad
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• MSL Rating: 3 (168 Hours)

Differing Parameter:

• Ratio - Input:Output: 4:6 (versus 4:10 in main part)

The substitute part differs only in the input-to-output ratio configuration. Selection between these parts depends on the specific output channel requirements of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the ZL40253LDG1 and ZL40250LDG1 maintain active product status with full ROHS3 compliance and identical electrical operating parameters. The primary selection criterion is the required number of output channels: the ZL40253LDG1 provides 10 outputs while the ZL40250LDG1 provides 6 outputs from the same 4-input configuration. Both devices are surface-mount compatible in the 56-VFQFN package with identical supply voltage ranges, frequency specifications, and temperature operating ranges. Moisture sensitivity level and REACH compliance are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ZL40253LDG1 and ZL40250LDG1?

A: The input-to-output ratio differs. The ZL40253LDG1 provides a 4:10 configuration while the ZL40250LDG1 provides a 4:6 configuration. All other electrical and mechanical specifications are identical.

Q: Can these parts be used interchangeably on the same PCB?

A: Both parts use the identical 56-VFQFN Exposed Pad package and have the same pinout footprint. However, the number of active output channels differs, so circuit design must account for the specific output channel count required by the application.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL rating of 3 (168 Hours).

Q: What supply voltage range do these parts support?

A: Both the ZL40253LDG1 and ZL40250LDG1 operate across 1.71V to 3.465V supply voltage range.

Q: What is the maximum operating frequency for both parts?

A: Both parts support clock frequencies up to 1.035 GHz.

Q: Are both parts currently available?

A: Yes. The ZL40253LDG1 has 1480 units in stock and the ZL40250LDG1 has 1149 units in stock.
