EL7104CS Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The EL7104CS is a low-side gate driver IC manufactured by Renesas Electronics Corporation, designed for driving N-Channel and P-Channel MOSFETs in power management applications. The device operates with a supply voltage range of 4.5V to 16V and delivers peak output currents of 4A (source and sink). The EL7104CS is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility through matching driven configuration, channel type, gate type, input type, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EL7104CS are qualified based on the following mandatory parameters:

• Driven Configuration: Low-Side (required match)
• Channel Type: Single (required match)
• Number of Drivers: 1 (required match)
• Gate Type: N-Channel, P-Channel MOSFET (required match)
• Input Type: Non-Inverting (required match)
• Package / Case: 8-SOIC (required match)
• Mounting Type: Surface Mount (required match)

Substitutes may vary in supply voltage range, peak output current, rise/fall time, operating temperature range, and compliance certifications, provided the core functional parameters remain compatible with the application requirements.

Parameter Comparison

Engineering Selection Recommendations

EL7104CSZ is a direct functional equivalent manufactured by Renesas Electronics Corporation. It maintains identical electrical specifications to the EL7104CS while offering active product status and ROHS3 compliance. The EL7104CSZ is available in tube packaging and represents the primary substitute for obsolete EL7104CS inventory replacement.

MIC4420ZM and MIC4420ZM-TR are functionally compatible substitutes manufactured by Microchip Technology. Both variants provide enhanced specifications including higher peak output current (6A versus 4A), extended supply voltage range (4.5V to 18V), and wider operating temperature range (0°C to 150°C). Both are ROHS3 compliant with MSL rating of 1 (Unlimited). The MIC4420ZM is supplied in tube packaging, while MIC4420ZM-TR is supplied in tape and reel format for automated assembly applications.

Selection between EL7104CSZ and MIC4420ZM/MIC4420ZM-TR variants depends on application requirements for output current capacity, supply voltage range, and temperature operating range. All three substitutes maintain the required low-side, single-channel, non-inverting gate driver configuration in 8-SOIC packaging.

Frequently Asked Questions (FAQ)

Q: Can EL7104CSZ directly replace EL7104CS in existing designs?

A: Yes. EL7104CSZ maintains identical electrical specifications and package configuration. The primary differences are active product status and ROHS3 compliance. No circuit modifications are required.

Q: What are the key differences between EL7104CSZ and MIC4420ZM?

A: Both are functionally compatible low-side gate drivers in 8-SOIC packaging. MIC4420ZM provides higher peak output current (6A versus 4A), extended supply voltage range (4.5V to 18V versus 4.5V to 16V), and wider operating temperature range (0°C to 150°C versus -40°C to 125°C). Rise and fall times are slower on MIC4420ZM (12ns/13ns versus 7.5ns/10ns).

Q: Are packaging differences between tube and tape & reel significant?

A: Tube packaging (EL7104CSZ, MIC4420ZM) is suitable for manual assembly and lower-volume production. Tape & reel packaging (MIC4420ZM-TR) is optimized for automated pick-and-place assembly in high-volume manufacturing.

Q: Do all substitutes meet RoHS compliance requirements?

A: EL7104CSZ, MIC4420ZM, and MIC4420ZM-TR are all ROHS3 compliant. The original EL7104CS is RoHS non-compliant.

Q: What is the moisture sensitivity level (MSL) impact on handling?

A: EL7104CSZ has MSL 3 (168 hours), requiring controlled storage and handling within 168 hours of package opening. MIC4420ZM and MIC4420ZM-TR have MSL 1 (Unlimited), allowing indefinite shelf life without moisture control measures.

Q: Can MIC4420ZM be used in applications requiring the full -40°C to 125°C temperature range?

A: No. MIC4420ZM operates from 0°C to 150°C. Applications requiring -40°C operation must use EL7104CSZ, which maintains the -40°C to 125°C range of the original EL7104CS.
