EL4543IU-T7 Equivalent & Substitute Parts

Part Overview

The EL4543IU-T7 is a video amplifier driver integrated circuit manufactured by Renesas Electronics Corporation, designed for differential output applications requiring high-speed signal conditioning. This linear amplifier operates across a wide supply voltage range and delivers 60 mA per channel output current with a 350 MHz bandwidth and 1000 V/µs slew rate.

The EL4543IU-T7 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain identical electrical performance parameters and mechanical compatibility while offering active product status and improved compliance certifications.

• Identical slew rate of 1000 V/µs
• Identical supply current of 14.5 mA
• Identical output current per channel of 60 mA
• Identical supply voltage range: 5V ~ 12V, ±2.5V ~ 6V
• Differential output configuration with three circuits

Mechanical Compatibility Requirements:

• Surface mount mounting type
• 24-SSOP package with 0.154" (3.90mm) width
• 24-QSOP supplier device package designation

Product Family Requirement:

• Base product number EL4543 from Renesas Electronics Corporation

The EL4543IUZ-T7 satisfies all substitution criteria, maintaining complete electrical and mechanical equivalence while offering improved product status and compliance certifications.

Engineering Selection Recommendations

The EL4543IUZ-T7 is the direct substitute for the obsolete EL4543IU-T7. Selection of the substitute part is based on the following engineering factors:

Product Status: The EL4543IU-T7 carries obsolete status, limiting availability and long-term supply assurance. The EL4543IUZ-T7 maintains active product status, ensuring continued manufacturing support and component availability.

Regulatory Compliance: The EL4543IUZ-T7 achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The original EL4543IU-T7 is RoHS non-compliant, presenting regulatory constraints for new designs and procurement.

Electrical and Mechanical Equivalence: All electrical parameters, including bandwidth, slew rate, supply current, output current, and supply voltage range, are identical between the main part and substitute. The 24-SSOP package and surface mount configuration are mechanically identical, enabling direct board-level substitution without layout modifications.

Supply Chain Continuity: The EL4543IUZ-T7 offers 1900 pieces in current inventory, compared to 971 pieces for the obsolete variant, providing improved supply chain stability for production and maintenance applications.

Regulatory Alignment: Both parts maintain identical REACH unaffected status and EAR99 export classification, with no changes to regulatory or trade compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the EL4543IUZ-T7 be used as a direct replacement for the EL4543IU-T7 in existing designs?

A: Yes. The EL4543IUZ-T7 is electrically and mechanically equivalent to the EL4543IU-T7. All electrical parameters, including bandwidth, slew rate, supply current, output current, and supply voltage specifications, are identical. The 24-SSOP package dimensions and surface mount configuration are unchanged, enabling direct substitution without circuit redesign or PCB layout modifications.

Q: What is the difference between the EL4543IU-T7 and EL4543IUZ-T7 part numbers?

A: The primary differences are product status and compliance certifications. The EL4543IU-T7 is obsolete and RoHS non-compliant, while the EL4543IUZ-T7 is an active product with ROHS3 compliance. The "Z" designation in the EL4543IUZ-T7 part number indicates the updated compliance variant. Electrical and mechanical specifications remain identical.

Q: Are there any packaging differences between these parts?

A: Both parts use identical 24-SSOP (0.154", 3.90mm width) surface mount packaging. The EL4543IU-T7 is supplied in standard packaging, while the EL4543IUZ-T7 is available in Cut Tape (CT) and Digi-Reel® packaging options. The physical component and pin configuration are unchanged.

Q: What is the moisture sensitivity level difference, and does it affect substitution?

A: The EL4543IU-T7 has MSL 1 (unlimited moisture sensitivity), while the EL4543IUZ-T7 has MSL 2 (1 year). MSL 2 represents standard moisture sensitivity with a one-year shelf life under controlled conditions. This difference does not affect electrical performance or functional substitution. Standard handling and storage practices for MSL 2 components are industry-standard.

Q: Why should I transition from the EL4543IU-T7 to the EL4543IUZ-T7?

A: Transition is recommended due to obsolete product status of the EL4543IU-T7. The EL4543IUZ-T7 offers active product status, ensuring continued manufacturing support, improved supply availability, and ROHS3 compliance for regulatory alignment. Electrical and mechanical equivalence ensures seamless integration into existing designs.

Q: Are there any supply voltage or current rating changes between these parts?

A: No. Both parts maintain identical supply voltage ranges (5V ~ 12V, ±2.5V ~ 6V), supply current (14.5 mA), and output current per channel (60 mA). All electrical specifications are unchanged.

Q: Can I use the EL4543IUZ-T7 in new designs?

A: Yes. The EL4543IUZ-T7 is the recommended choice for new designs. It offers active product status, ROHS3 compliance, and improved supply chain availability compared to the obsolete EL4543IU-T7. All electrical and mechanical specifications support direct implementation in video amplifier driver applications.
