Substitute Part Grouping Explanation

Substitution of the obsolete EL7155CSZ-T7A 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 gate driving
• Voltage - Supply: 4.5V ~ 16.5V range
• Current - Peak Output: 4.6A source and sink capability
• Input Type: Non-Inverting logic
• Package / Case: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Operating Temperature: -40°C ~ 125°C range
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected

The EL7155CSZ variant meets all substitution criteria while maintaining active product status, ensuring continued availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The EL7155CSZ is the direct active equivalent for the obsolete EL7155CSZ-T7A. Both parts are manufactured by Renesas Electronics Corporation and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: EL7155CSZ-T7A is obsolete while EL7155CSZ is active, ensuring ongoing manufacturer support, availability, and compliance with current regulatory standards including ROHS3 and REACH requirements. Selection of the EL7155CSZ eliminates obsolescence risk while preserving full functional compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the EL7155CSZ directly replace the EL7155CSZ-T7A in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including supply voltage range, output current capability, timing characteristics, package form factor, and operating temperature range. No circuit modifications are required.

Q: What is the difference between EL7155CSZ-T7A and EL7155CSZ?

A: The primary difference is product status. EL7155CSZ-T7A is classified as obsolete, while EL7155CSZ is active. The suffix designation (-T7A) indicates a specific packaging or distribution variant of the obsolete line. The base part number EL7155 and core specifications remain identical.

Q: Are there any packaging differences between these parts?

A: Both parts use the 8-SOIC package with identical dimensions (0.154" or 3.90mm width). The EL7155CSZ-T7A was supplied in standard packaging, while EL7155CSZ is available in tube packaging. Both are surface-mount components with identical PCB footprints and soldering requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EL7155CSZ-T7A and EL7155CSZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 3, requiring storage conditions of 168 hours maximum at specified humidity levels before soldering. Standard moisture-barrier packaging and handling procedures apply to both variants.
