Parameter Comparison

Engineering Selection Recommendations

The ISL68134IRAZ-T is the direct substitute for the ISL68134IRAZ. Both parts share identical electrical specifications, package geometry, and regulatory compliance certifications. The primary distinction is product status and packaging format.

ISL68134IRAZ-T Selection Rationale:

The ISL68134IRAZ-T maintains Active product status with Renesas Electronics Corporation, ensuring ongoing manufacturer support and supply chain availability. This part is supplied in Tape & Reel (TR) packaging, which is standard for production environments and automated assembly processes.

All electrical parameters, thermal operating ranges, and compliance certifications (ROHS3, REACH Unaffected, EAR99) are identical between the main part and substitute. The 40-TQFN (5x5) package footprint and 40-WFQFN Exposed Pad case specification ensure mechanical and thermal compatibility without PCB redesign.

For applications currently utilizing the obsolete ISL68134IRAZ, transition to ISL68134IRAZ-T provides equivalent functionality with improved supply chain continuity and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can ISL68134IRAZ-T be used as a direct replacement for ISL68134IRAZ?
