Engineering Selection Recommendations

The ISL68124IRAZ-T is the direct substitute for the ISL68124IRAZ. Both components share identical electrical specifications, physical package dimensions, and regulatory compliance certifications. The primary distinction between these parts is product status and packaging configuration.

Product Status Consideration: The ISL68124IRAZ is classified as obsolete, while the ISL68124IRAZ-T maintains active product status with Renesas Electronics Corporation. For new designs, ongoing production, and long-term supply chain planning, the ISL68124IRAZ-T is the appropriate selection.

Packaging Configuration: The ISL68124IRAZ is supplied in bulk packaging, whereas the ISL68124IRAZ-T is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides superior protection during storage and transportation. This packaging difference does not affect electrical or mechanical compatibility.

Compliance & Regulatory Status: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity specifications. No additional qualification or testing is required when transitioning from the ISL68124IRAZ to the ISL68124IRAZ-T.

Frequently Asked Questions (FAQ)

Q: Can the ISL68124IRAZ-T be used as a direct replacement for the ISL68124IRAZ in existing designs?

A: Yes. The ISL68124IRAZ-T is electrically and mechanically equivalent to the ISL68124IRAZ. All electrical parameters, package dimensions, pin configurations, and regulatory certifications are identical. No design modifications are required.

Q: What is the difference between bulk packaging and Tape & Reel (TR) packaging?

A: Bulk packaging supplies components loose or in trays, suitable for manual handling or small-volume applications. Tape & Reel packaging places components in standardized carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Both packaging formats contain identical components with no functional differences.

Q: Why is the ISL68124IRAZ classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, production lifecycle, and technology evolution. The ISL68124IRAZ-T remains in active production and is the recommended part for all new applications and ongoing supply requirements.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both the ISL68124IRAZ and ISL68124IRAZ-T operate within identical voltage ranges (3.135V ~ 3.465V), supply current specifications (63 mA), and temperature ranges (-40°C ~ 85°C). Thermal and electrical performance characteristics are equivalent.

Q: What is the Moisture Sensitivity Level (MSL) 3 specification?

A: MSL 3 indicates the component can be exposed to moisture for a maximum of 168 hours at 85°C and 85% relative humidity before soldering. Both parts carry this identical specification and require standard moisture control handling during storage and assembly.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the ISL68124IRAZ and ISL68124IRAZ-T are RoHS3 compliant and REACH unaffected. They meet current environmental and hazardous substance restrictions for electronic components in regulated markets.
