EL7155CS-T7 Equivalent & Substitute Parts

Part Overview

The EL7155CS-T7 is a high-side or low-side gate driver IC manufactured by Renesas Electronics Corporation, designed for IGBT gate driving applications. This non-inverting synchronous driver operates across a 4.5V to 16.5V supply voltage range and delivers 4.6A peak output current in both source and sink configurations. The device is packaged in an 8-SOIC surface mount package with a 3.90mm width.

The EL7155CS-T7 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this gate driver topology.

Substitute Part Grouping Explanation

Substitution eligibility for the EL7155CS-T7 is determined by strict equivalence across the following critical parameters:

• Driven Configuration: High-Side or Low-Side capability
• Channel Type: Synchronous operation
• Number of Drivers: 2-channel configuration
• Gate Type: IGBT compatibility
• Voltage - Supply: 4.5V ~ 16.5V range
• Logic Voltage Thresholds: VIL 0.8V, VIH 2.4V
• Current - Peak Output: 4.6A source and sink capability
• Input Type: Non-Inverting logic
• Rise / Fall Time: 14.5ns rise, 15ns fall (typical)
• Operating Temperature: -40°C ~ 125°C junction temperature range
• Package / Case: 8-SOIC form factor with 3.90mm width
• Moisture Sensitivity Level: MSL 1

The EL7155CSZ-T7 meets all electrical and mechanical substitution criteria. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The EL7155CSZ-T7 is the direct functional equivalent of the EL7155CS-T7. Both parts share identical electrical specifications and mechanical form factors. Selection between these parts should be based on the following criteria:

Product Status: The EL7155CSZ-T7 maintains Active product status, ensuring continued manufacturer support and long-term availability. The EL7155CS-T7 is classified as Obsolete, indicating discontinued production and limited future supply.

Compliance Certification: The EL7155CSZ-T7 is ROHS3 compliant, meeting current environmental and regulatory requirements. The EL7155CS-T7 is RoHS non-compliant, which may present regulatory constraints in certain applications or markets.

Packaging Format: The EL7155CSZ-T7 is supplied in Tape & Reel format, suitable for automated assembly processes. The EL7155CS-T7 is supplied in bulk packaging. Packaging selection depends on production volume and assembly methodology.

For new designs or ongoing production requiring long-term component availability and regulatory compliance, the EL7155CSZ-T7 is the appropriate selection. For legacy system maintenance where existing inventory of EL7155CS-T7 is available, direct substitution is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Are the EL7155CS-T7 and EL7155CSZ-T7 electrically interchangeable?

A: Yes. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical specifications, including supply voltage range (4.5V ~ 16.5V), peak output current (4.6A source and sink), logic voltage thresholds (0.8V, 2.4V), and timing characteristics (14.5ns rise, 15ns fall). They are direct functional equivalents.

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

A: The primary differences are product status, packaging format, and RoHS compliance. The EL7155CSZ-T7 is Active with ROHS3 compliance and Tape & Reel packaging. The EL7155CS-T7 is Obsolete with RoHS non-compliance and bulk packaging.

Q: Can I use EL7155CSZ-T7 in place of EL7155CS-T7 in existing designs?

A: Yes. The EL7155CSZ-T7 is mechanically and electrically compatible. Both use the 8-SOIC package with 3.90mm width and identical pinout. No circuit modifications are required.

Q: Why is the EL7155CS-T7 marked as Obsolete?

A: Obsolete status indicates that Renesas Electronics Corporation has discontinued production of this specific part number. The EL7155CSZ-T7 represents the current production equivalent.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel and bulk packaging formats contain identical die and internal construction. Packaging format affects only procurement, storage, and assembly handling. Electrical and thermal performance remain unchanged.

Q: Are there any temperature or voltage derating considerations when substituting?

A: No. Both parts operate across the identical temperature range (-40°C ~ 125°C junction temperature) and supply voltage range (4.5V ~ 16.5V). No derating adjustments are necessary.

Q: What is the significance of ROHS3 compliance on the EL7155CSZ-T7?

A: ROHS3 compliance indicates conformance to current Restriction of Hazardous Substances regulations. This certification is required for many applications and markets. The EL7155CS-T7 lacks this certification, which may restrict its use in regulated environments.
