Parameter Comparison

Engineering Selection Recommendations

The EL4543IUZ-T13 is the direct substitute for the obsolete EL4543IU-T13. All critical electrical and mechanical parameters are identical, ensuring functional equivalence in circuit applications.

Product Status Advantage: The EL4543IUZ-T13 carries an active product status with current manufacturing support from Renesas Electronics Corporation, whereas the EL4543IU-T13 is obsolete. This transition provides access to ongoing component availability and supply chain stability.

Compliance Improvement: The EL4543IUZ-T13 achieves ROHS3 compliance, representing an improvement over the RoHS non-compliant status of the EL4543IU-T13. This compliance upgrade supports modern manufacturing and environmental regulatory requirements.

Moisture Sensitivity Consideration: The EL4543IUZ-T13 carries an MSL rating of 2 (1 Year), compared to the MSL 1 (Unlimited) rating of the EL4543IU-T13. This difference reflects standard industry practice for active production components and does not affect functional substitution in typical storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the EL4543IUZ-T13 be used as a direct replacement for the EL4543IU-T13?

A: Yes. The EL4543IUZ-T13 is a direct substitute. All electrical parameters including bandwidth, slew rate, supply current, output current, and supply voltage specifications are identical. The mechanical package, pin configuration, and mounting type are also identical.

Q: What is the primary reason to transition from EL4543IU-T13 to EL4543IUZ-T13?

A: The EL4543IU-T13 is obsolete with no active manufacturing support. The EL4543IUZ-T13 is an active product with current availability from Renesas Electronics Corporation, ensuring long-term supply chain continuity.

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

A: No. Both parts deliver identical electrical performance across all specified parameters: 350 MHz bandwidth, 1000 V/µs slew rate, 14.5 mA supply current, 60 mA output current per channel, and identical supply voltage ranges.

Q: Will the EL4543IUZ-T13 fit in the same PCB footprint as the EL4543IU-T13?

A: Yes. Both parts use the 24-SSOP package with identical dimensions (0.154" width, 3.90mm width). Pin-to-pin compatibility is maintained, allowing direct PCB substitution without layout modifications.

Q: What is the difference in RoHS compliance between these parts?

A: The EL4543IU-T13 is RoHS non-compliant. The EL4543IUZ-T13 is ROHS3 compliant. For applications subject to RoHS regulatory requirements, the EL4543IUZ-T13 provides the necessary compliance certification.

Q: Does the MSL rating difference affect substitution?

A: The MSL rating difference (1 versus 2) reflects standard industry practice for obsolete versus active products. Both ratings are suitable for typical component storage and handling. The MSL 2 (1 Year) rating of the EL4543IUZ-T13 is standard for active production components and does not impact functional substitution.

Q: Are both parts manufactured by Renesas Electronics Corporation?

A: Yes. Both the EL4543IU-T13 and EL4543IUZ-T13 are manufactured by Renesas Electronics Corporation, ensuring consistent quality and design specifications.
