EL7457CS-T7 Equivalent & Substitute Parts

Part Overview

The EL7457CS-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 16-SOIC surface mount device operates across a 4.5V to 18V supply range with 4 independent driver channels and peak output current of 2A source/sink capability.

The EL7457CS-T7 is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure continued design support, maintain supply chain reliability, and access components with active manufacturing status and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL7457CS-T7 is determined by strict equivalence across the following critical parameters:

• Package / Case: 16-SOIC form factor with identical 0.154" (3.90mm) width
• Number of Drivers: 4 independent channels
• Driven Configuration: High-Side or Low-Side capability
• Gate Type: N-Channel and P-Channel MOSFET support
• Voltage - Supply: 4.5V ~ 18V operating range
• Current - Peak Output: 2A source and 2A sink capability
• Input Type: Non-Inverting logic
• Rise / Fall Time: 14.6ns rise, 13ns fall (typical)
• Operating Temperature: -40°C ~ 85°C
• Logic Voltage Thresholds: VIL 0.8V, VIH 2V

The EL7457CSZ-T7 meets all these criteria and is therefore a direct functional equivalent. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The EL7457CSZ-T7 is the direct substitute for the obsolete EL7457CS-T7. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications across all functional parameters.

Selection of the EL7457CSZ-T7 is supported by the following factors:

• Active product status ensures ongoing manufacturing support and supply chain availability
• ROHS3 compliance meets current environmental and regulatory requirements
• Identical electrical performance across all gate driver specifications
• Pin-compatible 16-SOIC package with no PCB redesign required
• Available in Cut Tape and Digi-Reel packaging options for production flexibility

The EL7457CSZ-T7 is suitable for direct replacement in all applications previously designed with the EL7457CS-T7, with no functional or performance degradation.

Frequently Asked Questions (FAQ)

Q: Are the EL7457CS-T7 and EL7457CSZ-T7 pin-compatible?

A: Yes. Both parts use the 16-SOIC package with identical pinout and electrical characteristics. No PCB modification is required for substitution.

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

A: The primary differences are product status and compliance certifications. The EL7457CS-T7 is obsolete and RoHS non-compliant, while the EL7457CSZ-T7 is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I use the EL7457CSZ-T7 in existing designs using the EL7457CS-T7?

A: Yes. The EL7457CSZ-T7 is a direct functional equivalent with identical supply voltage range, output current, timing characteristics, and operating temperature range. No design changes are necessary.

Q: What does the MSL rating difference mean?

A: MSL (Moisture Sensitivity Level) indicates moisture exposure limits during storage and handling. The EL7457CS-T7 has MSL 1 (unlimited exposure), while the EL7457CSZ-T7 has MSL 3 (168-hour limit). This affects storage conditions but does not impact electrical performance or substitutability.

Q: Are both parts available from the same manufacturer?

A: Yes. Both the EL7457CS-T7 and EL7457CSZ-T7 are manufactured by Renesas Electronics Corporation.

Q: What packaging options are available for the substitute part?

A: The EL7457CSZ-T7 is available in Cut Tape (CT) and Digi-Reel packaging options, providing flexibility for both prototype and production volume requirements.
