ISL6617IRZ PWM Doubler PMIC Equivalent & Substitute Parts

Part Overview

The ISL6617IRZ is a PWM Doubler Monitor integrated circuit manufactured by Renesas Electronics Corporation, designed for power management applications requiring precise PWM control in a compact 10-DFN (3x3) surface mount package. This component operates within a 4.5V to 5.5V supply voltage range and delivers 6mA supply current, making it suitable for embedded power conversion systems.

The ISL6617IRZ carries a Last Time Buy product status, indicating that this specific packaging configuration (Tube) is being discontinued. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL6617IRZ is determined by strict equivalence across the following critical parameters:

• Identical base product number (ISL6617)
• Matching package specification (10-DFN 3x3 with exposed pad)
• Identical electrical ratings (4.5V ~ 5.5V supply, 6mA current)
• Identical operating temperature range (-40°C ~ 85°C)
• Equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Identical moisture sensitivity level (MSL 3)

The primary distinction between the main part and its substitute lies in packaging format and product lifecycle status. The ISL6617IRZ-T variant maintains full electrical and mechanical compatibility while offering an alternative distribution format suited for continuous production environments.

Parameter Comparison

Engineering Selection Recommendations

The ISL6617IRZ-T is the direct functional equivalent of the ISL6617IRZ. Both parts share identical electrical specifications, thermal characteristics, and compliance certifications. The ISL6617IRZ-T maintains Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the tube-packaged variant.

Selection between these parts should be based on packaging requirements and procurement logistics. The Tape & Reel format of the ISL6617IRZ-T is optimized for automated assembly processes and high-volume production environments. The tube packaging of the ISL6617IRZ is suitable for lower-volume applications or manual assembly workflows, though this variant is subject to discontinuation.

Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements. No functional or electrical compromises exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can ISL6617IRZ-T be used as a direct replacement for ISL6617IRZ?

A: Yes. Both parts are electrically and mechanically identical. The ISL6617IRZ-T differs only in packaging format (Tape & Reel versus Tube) and product lifecycle status (Active versus Last Time Buy). No circuit modifications or design changes are required.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging contains loose components in a plastic tube, suitable for manual handling and lower-volume assembly. Tape & Reel packaging places components on a continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly equipment. Both formats contain identical die and lead configurations.

Q: Are there any thermal or electrical performance differences?

A: No. Both variants operate within identical voltage ranges (4.5V ~ 5.5V), supply current specifications (6mA), and temperature ranges (-40°C ~ 85°C). Thermal performance and electrical characteristics are equivalent.

Q: What does Last Time Buy status mean for the ISL6617IRZ?

A: Last Time Buy indicates that Renesas Electronics Corporation will discontinue manufacturing this specific part variant (tube packaging). Existing inventory may be available for a limited period. The ISL6617IRZ-T (Tape & Reel variant) remains in Active production status.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both ISL6617IRZ and ISL6617IRZ-T are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry identical Moisture Sensitivity Level (MSL 3) ratings. No compliance differences exist between the variants.

Q: Which part should be selected for new designs?

A: The ISL6617IRZ-T is recommended for new designs due to its Active product status and suitability for automated manufacturing processes. This ensures long-term supply availability and compatibility with modern assembly workflows.
