Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL6617AFRZ is determined by strict equivalence across the following critical parameters:

• Identical base product number (ISL6617)
• Matching package specification (10-VFDFN Exposed Pad / 10-DFN 3x3)
• Identical electrical ratings (4.5V ~ 5.5V supply, 6mA supply current)
• Matching operating temperature range (-40°C ~ 125°C)
• Equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Identical moisture sensitivity level (MSL 3)

The primary distinction between the main part and its substitute is packaging format: tube versus tape & reel, and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The ISL6617AFRZ-T is the direct functional equivalent of the ISL6617AFRZ. Both parts share identical electrical specifications, package geometry, and compliance certifications. The ISL6617AFRZ-T maintains active product status with Renesas Electronics Corporation, ensuring continued manufacturing support and component availability.

Selection between these parts is determined by packaging requirements: tube packaging for low-volume or manual assembly applications, and tape & reel packaging for automated production environments. The tape & reel variant (ISL6617AFRZ-T) is preferred for new designs and high-volume production due to active product status and superior inventory availability (55,143 units versus 6,810 units).

Frequently Asked Questions (FAQ)

Q: Can ISL6617AFRZ-T be used as a direct replacement for ISL6617AFRZ?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format (tube versus tape & reel) and product status. The ISL6617AFRZ-T is the active production equivalent.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging is suitable for manual handling and low-volume assembly. Tape & reel packaging is designed for automated pick-and-place equipment and high-volume production. Both formats contain the same component with identical electrical performance.

Q: Why is the ISL6617AFRZ marked as obsolete?

A: Renesas Electronics Corporation has transitioned this product to the tape & reel format (ISL6617AFRZ-T) as the active production variant. The tube format is no longer manufactured.

Q: Are there any electrical differences between ISL6617AFRZ and ISL6617AFRZ-T?

A: No. Both parts have identical voltage supply range (4.5V ~ 5.5V), supply current (6mA), operating temperature range (-40°C ~ 125°C), and all other electrical specifications.

Q: What compliance certifications apply to both parts?

A: Both ISL6617AFRZ and ISL6617AFRZ-T are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is MSL 3 (168 hours).
