EL7457CU-T7 Equivalent & Substitute Parts

Part Overview

The EL7457CU-T7 is a high-side or low-side gate driver IC manufactured by Renesas Electronics Corporation, designed for independent control of N-Channel and P-Channel MOSFETs. This non-inverting gate driver operates across a 4.5V to 18V supply range with 4 independent driver channels and peak output current capability of 2A source and 2A sink.

The EL7457CU-T7 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this gate driver topology.

• Voltage Supply Range: 4.5V ~ 18V
• Peak Output Current: 2A source and 2A sink capability
• Input Type: Non-Inverting logic
• Package / Case: 16-SSOP form factor with identical pinout
• Rise / Fall Time: 14.6ns rise, 13ns fall (typical)
• Operating Temperature Range: -40°C ~ 85°C

The EL7457CUZ-T7 meets all substitution criteria as a direct equivalent, maintaining identical electrical specifications and mechanical compatibility while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The EL7457CUZ-T7 is the direct substitute for the obsolete EL7457CU-T7. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in gate driver applications.

The EL7457CUZ-T7 offers the following advantages:

• Active Product Status: Currently manufactured and supported by Renesas Electronics Corporation, ensuring long-term availability and supply chain stability
• RoHS3 Compliance: Meets current environmental and regulatory requirements, whereas the EL7457CU-T7 is RoHS non-compliant
• Improved Moisture Sensitivity: MSL rating of 2 (1 Year) provides adequate protection for standard storage and handling conditions

No electrical performance degradation occurs with this substitution. The EL7457CUZ-T7 maintains the same 4-channel independent gate driver architecture, output current capability, timing characteristics, and operating temperature range as the original part.

Frequently Asked Questions (FAQ)

Q: Are the EL7457CU-T7 and EL7457CUZ-T7 pin-compatible?

A: Yes. Both parts use the 16-SSOP package with identical pinout and mechanical dimensions (0.154" width, 3.90mm). Direct PCB substitution is possible without layout modifications.

Q: What is the difference between the EL7457CU-T7 and EL7457CUZ-T7?

A: The parts are electrically and functionally identical. The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and moisture sensitivity level (MSL 1 vs. MSL 2). The EL7457CUZ-T7 is the current production equivalent.

Q: Can I use the EL7457CUZ-T7 in existing designs specified for the EL7457CU-T7?

A: Yes. The EL7457CUZ-T7 is a direct functional and mechanical equivalent. No circuit modifications, firmware changes, or design re-qualification are required for substitution.

Q: Does the EL7457CUZ-T7 support the same supply voltage range?

A: Yes. Both parts operate across 4.5V to 18V supply voltage range with identical logic voltage thresholds (VIL = 0.8V, VIH = 2V).

Q: What is the significance of the RoHS3 compliance difference?

A: The EL7457CUZ-T7 meets ROHS3 (Restriction of Hazardous Substances Directive 3) requirements, making it suitable for applications subject to EU environmental regulations. The EL7457CU-T7 does not meet these requirements.

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

A: No. Both parts share identical rise time (14.6ns typical), fall time (13ns typical), peak output current (2A source, 2A sink), and operating temperature range (-40°C to 85°C).
