Key Parameters

Substitute Part Grouping Explanation

The ZL40292LDF1 qualifies as a parametric equivalent to the ZL40293LDF1 based on the following substitution criteria:

Electrical Specifications Match:

• Identical 1:20 input-to-output ratio
• Identical differential input and output configuration
• Identical clock input and HCSL output signal types
• Identical maximum frequency of 250 MHz
• Identical supply voltage range of 3.135V ~ 3.465V
• Identical operating temperature range of -40°C ~ 85°C

Mechanical Compatibility:

• Identical package type: 72-VFQFN Exposed Pad
• Identical supplier device package: 72-QFN (10x10)
• Identical surface mount mounting type

Compliance & Regulatory:

• Identical RoHS3 compliance status
• Identical MSL rating of 3 (168 Hours)
• Identical REACH Unaffected status

Difference: The only distinction between these parts is the packaging format: ZL40293LDF1 is supplied in Cut Tape (CT), while ZL40292LDF1 is supplied in Tape & Reel (TR). This difference affects procurement and handling but does not impact electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the ZL40293LDF1 and ZL40292LDF1 are Active products from Microchip Technology with full ROHS3 compliance and REACH Unaffected status, making them suitable for regulated applications. Selection between these parts should be based on procurement requirements and supply chain considerations:

The ZL40293LDF1 in Cut Tape packaging is appropriate for lower-volume applications or when individual component handling is required. The ZL40292LDF1 in Tape & Reel format is suitable for high-volume production environments where automated pick-and-place assembly is employed. Both parts maintain identical electrical performance and thermal characteristics across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can ZL40292LDF1 be used as a direct replacement for ZL40293LDF1?

A: Yes. The ZL40292LDF1 is electrically and mechanically identical to the ZL40293LDF1. The only difference is the packaging format (Tape & Reel versus Cut Tape), which does not affect circuit performance or compatibility.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies individual components on tape segments, suitable for small quantities and manual assembly. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for automated assembly equipment and high-volume production.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate identically across all electrical specifications, frequency ranges, supply voltage, and temperature ranges. Performance is determined by the die and internal circuitry, which are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ZL40293LDF1 and ZL40292LDF1 are ROHS3 compliant, REACH Unaffected, and carry identical MSL ratings of 3 (168 Hours).

Q: Which part should I select for my application?

A: Selection depends on your assembly process and volume requirements. For automated production lines, use ZL40292LDF1 (Tape & Reel). For manual assembly or prototyping, use ZL40293LDF1 (Cut Tape). Both deliver identical circuit performance.
