• Output phases: 7 phases required
• Output configuration: Positive output only
• Supply voltage range: 3.135V ~ 3.465V
• Switching frequency range: 200kHz ~ 1MHz
• Serial interface: PMBus protocol support
• Operating temperature range: -40°C ~ 85°C (TA)

Mechanical Compatibility Parameters:

• Package type: 48-VFQFN Exposed Pad
• Device package: 48-QFN (6x6)
• Mounting type: Surface Mount

Compliance & Regulatory Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS Code: 8542.39.0001

Substitute parts must match all parameters listed above. The ISL68127IRAZ shares the same base product number (ISL68127) with its substitute, confirming functional and architectural equivalence within the Renesas ISL68127 controller family.

Parameter Comparison

Engineering Selection Recommendations

The ISL68127IRAZ-T is the manufacturer-recommended substitute for the obsolete ISL68127IRAZ. Both components are manufactured by Renesas Electronics Corporation and share identical electrical, mechanical, and regulatory specifications.

Key Selection Factors:

Product Status Consideration: The ISL68127IRAZ is classified as obsolete, while the ISL68127IRAZ-T maintains active product status. Active status ensures ongoing manufacturer support, availability, and compliance maintenance.

Compliance Alignment: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 3, 168 hours). Regulatory and environmental compliance requirements are fully satisfied by the substitute part.

Packaging Difference: The primary distinction between the main part and substitute is packaging format. The ISL68127IRAZ is supplied in bulk packaging, while the ISL68127IRAZ-T is supplied in Tape & Reel (TR) format. This difference does not affect electrical or mechanical compatibility and is determined by supply chain and manufacturing requirements.

Functional Equivalence: Both parts operate as 7-phase PMBus digital PWM controllers with identical electrical specifications, including supply voltage range (3.135V ~ 3.465V), switching frequency range (200kHz ~ 1MHz), and operating temperature range (-40°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can the ISL68127IRAZ-T be used as a direct replacement for the ISL68127IRAZ?

A: Yes. The ISL68127IRAZ-T is electrically and mechanically equivalent to the ISL68127IRAZ. Both components share identical pin configurations, package dimensions (48-QFN 6x6), electrical specifications, and regulatory compliance status. The substitute part is suitable for direct replacement in existing designs.

Q: What is the difference between ISL68127IRAZ and ISL68127IRAZ-T?

A: The primary difference is packaging format. The ISL68127IRAZ is supplied in bulk packaging, while the ISL68127IRAZ-T is supplied in Tape & Reel (TR) format. Additionally, the ISL68127IRAZ-T maintains active product status, whereas the ISL68127IRAZ is obsolete. All electrical and mechanical specifications are identical.

Q: Are there any pin configuration differences between these parts?

A: No. Both the ISL68127IRAZ and ISL68127IRAZ-T use the 48-VFQFN Exposed Pad package with identical pin assignments and electrical characteristics. PCB layout and schematic designs require no modification.

Q: Does the Tape & Reel packaging of the ISL68127IRAZ-T affect performance?

A: No. Tape & Reel packaging is a supply and assembly format only. It does not affect component performance, electrical characteristics, or reliability. The internal die and electrical specifications remain identical to the bulk-packaged version.

Q: What is the operating temperature range for both parts?

A: Both the ISL68127IRAZ and ISL68127IRAZ-T operate across the temperature range of -40°C to 85°C (TA). This specification is identical for both components.

Q: Are both parts RoHS compliant?

A: Yes. Both the ISL68127IRAZ and ISL68127IRAZ-T are ROHS3 compliant and REACH unaffected. They meet all applicable environmental and regulatory requirements.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 3 with a floor life of 168 hours. Proper handling and storage procedures must be followed to maintain component integrity.

Q: Why is the ISL68127IRAZ classified as obsolete?

A: The ISL68127IRAZ has reached end-of-life status in the manufacturer's product portfolio. The ISL68127IRAZ-T, with identical specifications and active product status, is the recommended replacement for ongoing production and new designs.

Q: Can I use the ISL68127IRAZ-T in new product designs?

A: Yes. The ISL68127IRAZ-T is the active product variant and is suitable for new designs. It provides the same 7-phase PMBus digital PWM controller functionality with full manufacturer support and compliance certification.
