Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCLVD1212RHAR is determined by the following critical parameters:

Functional Equivalence Criteria:

• Input:Output ratio of 2:12 (mandatory)
• Differential input and LVDS output capability (mandatory)
• Surface mount package with 40-pin QFN form factor (mandatory)
• Operating temperature range of -40°C to 85°C (mandatory)

Compliance & Reliability Criteria:

• ROHS3 compliance status
• Active product status
• EAR99 export classification
• HTSUS commodity code alignment (8542.39.0001)

The PI6C5921512ZDIEX qualifies as a substitute part because it maintains the 2:12 input:output ratio, supports differential input with LVDS output, operates across the required temperature range, and is housed in a compatible 40-pin QFN package. Both parts are ROHS3 compliant and active products.

Parameter Comparison

Engineering Selection Recommendations

Both the CDCLVD1212RHAR and PI6C5921512ZDIEX are active products with ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on the following provided specifications:

CDCLVD1212RHAR is suitable for applications with maximum frequency requirements up to 800 MHz and supply voltage constrained to the 2.375V to 2.625V range. This part carries MSL 3 moisture sensitivity.

PI6C5921512ZDIEX supports higher maximum frequency operation (1.5 GHz) and accommodates a wider supply voltage range (2.375V to 3.465V). This part carries MSL 1 moisture sensitivity, indicating superior moisture resistance characteristics.

Both parts maintain the required 2:12 input:output ratio, differential input capability, and LVDS output configuration. Package form factors are both 40-pin QFN with exposed pad designs, suitable for surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can the PI6C5921512ZDIEX directly replace the CDCLVD1212RHAR in existing designs?

A: Direct replacement is possible when the application operates at frequencies up to 800 MHz and supply voltage remains within 2.375V to 2.625V. The PI6C5921512ZDIEX supports these specifications and maintains identical input:output ratio and signal types. PCB layout compatibility should be verified due to potential minor package dimension variations between 40-VFQFN and 40-WFQFN packages.

Q: What are the key differences between these two parts?

A: The primary differences are maximum frequency rating (800 MHz vs. 1.5 GHz), supply voltage range (2.375V-2.625V vs. 2.375V-3.465V), and moisture sensitivity level (MSL 3 vs. MSL 1). Functional specifications for the 2:12 distribution ratio and signal types remain equivalent.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are ROHS3 compliant and carry active product status. The PI6C5921512ZDIEX offers improved moisture resistance (MSL 1 vs. MSL 3), which may be advantageous for applications with extended storage or humid environment exposure.

Q: What packaging considerations apply to these parts?

A: Both parts use 40-pin QFN surface mount packages with exposed pads. The CDCLVD1212RHAR uses 40-VFQFN packaging while the PI6C5921512ZDIEX uses 40-WFQFN packaging. Verify PCB footprint compatibility and thermal management requirements for your specific application before substitution.

Q: Can the PI6C5921512ZDIEX be used in applications requiring only 800 MHz operation?

A: Yes. The PI6C5921512ZDIEX is rated for 1.5 GHz maximum frequency, so it operates within specification at 800 MHz. Supply voltage and temperature range requirements must still be verified against your application design parameters.
