Engineering Selection Recommendations

The PI3USB31532ZLCEX is the direct substitute for the obsolete PI3USB31532ZLEX. Both components share the same base product number (PI3USB31532) and maintain identical electrical and mechanical specifications across all critical parameters.

The PI3USB31532ZLCEX offers the advantage of active product status, ensuring continued manufacturer support and supply chain availability. The component exceeds the minimum bandwidth requirement with 8.3GHz performance versus the 8GHz specification of the original part. Both parts maintain full ROHS3 compliance and REACH unaffected status.

The transition from tube packaging (PI3USB31532ZLEX) to tape and reel packaging (PI3USB31532ZLCEX) reflects standard manufacturing practices for active products and supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PI3USB31532ZLCEX be used as a direct replacement for PI3USB31532ZLEX?

A: Yes. Both parts are manufactured by Diodes Incorporated, share identical channel configuration, supply voltage requirements, operating temperature range, and package footprint (40-WFQFN Exposed Pad). The PI3USB31532ZLCEX maintains active product status and meets all electrical specifications of the obsolete part.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. The PI3USB31532ZLEX is obsolete and supplied in tube packaging. The PI3USB31532ZLCEX is an active product supplied in tape and reel format, with a marginally higher bandwidth specification (8.3GHz versus 8GHz).

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical 40-WFQFN Exposed Pad package with 40-TQFN (3x6) footprint dimensions. PCB layouts, solder pad patterns, and thermal management designs require no modification.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both PI3USB31532ZLEX and PI3USB31532ZLCEX are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: What supply voltage range is required for operation?

A: Both parts operate with a single supply voltage range of 3V to 3.6V. No dual supply configuration is required.
