EL7457CL Equivalent & Substitute Parts

Part Overview

The EL7457CL 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 in 16-QFN (4x4) surface mount packaging. This component operates across a 4.5V to 18V supply voltage range with non-inverting logic inputs and symmetric 2A peak output drive capability.

The EL7457CL is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or ongoing production requirements. The substitute part EL7457CLZ maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL7457CL is determined by strict equivalence across the following critical parameters:

• Driven configuration (high-side or low-side capability)
• Number of independent driver channels (4 channels)
• Gate type compatibility (N-Channel and P-Channel MOSFET support)
• Supply voltage range (4.5V ~ 18V)
• Logic input voltage thresholds (VIL 0.8V, VIH 2V)
• Peak output current specifications (2A source, 2A sink)
• Input logic polarity (non-inverting)
• Switching characteristics (rise/fall times 14.6ns / 13ns)
• Operating temperature range (-40°C ~ 85°C)
• Physical package form factor (16-QFN 4x4 with exposed pad)

The EL7457CLZ qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The EL7457CLZ is the appropriate selection for applications currently using or specifying the EL7457CL. The substitute part maintains complete electrical and mechanical compatibility while offering the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance satisfies regulatory requirements for new product designs and manufacturing in restricted substance environments
• Tube packaging provides standard handling and storage conditions for production environments

The EL7457CL should not be selected for new designs due to obsolete status. Existing designs using the EL7457CL can transition to the EL7457CLZ without circuit modification or re-qualification, provided that the MSL 3 moisture sensitivity requirement (168-hour floor life) is accommodated in manufacturing and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can the EL7457CLZ be used as a direct replacement for the EL7457CL in existing designs?

A: Yes. The EL7457CLZ is electrically and mechanically identical to the EL7457CL across all functional parameters including supply voltage, output current, switching characteristics, and package form factor. No circuit changes are required.

Q: What is the difference between the EL7457CL and EL7457CLZ?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and moisture sensitivity level (MSL 1 vs. MSL 3). Electrical performance and package specifications are identical.

Q: Does the MSL 3 rating of the EL7457CLZ affect compatibility?

A: The MSL 3 rating requires that the component be used within 168 hours of package opening in standard manufacturing environments. This is a handling and storage requirement, not a functional limitation. Standard manufacturing practices accommodate this specification.

Q: Are there any other Renesas gate driver alternatives with different specifications?

A: Substitution is limited to parts meeting all specified electrical and mechanical parameters. Only the EL7457CLZ meets the complete parameter set for the EL7457CL.

Q: What is the base product number for these parts?

A: Both the EL7457CL and EL7457CLZ share the base product number EL7457, with suffixes indicating packaging and compliance variations.
