Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL6121HIB is determined by strict alignment of the following parameters:

• Package type and physical dimensions (8-SOIC, 0.154" width, 3.90mm)
• Supply voltage operating range (2.5V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Functional classification (Single Supply/Current Limiting Controller)
• Mounting technology (Surface Mount)

The ISL6121HIBZA meets all substitution criteria as it shares identical electrical specifications, package configuration, and functional purpose with the main part number.

Parameter Comparison

Engineering Selection Recommendations

The ISL6121HIBZA serves as a direct functional equivalent to the ISL6121HIB. Both components are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications. The primary distinction is the RoHS compliance status: the ISL6121HIB is RoHS non-compliant, while the ISL6121HIBZA is ROHS3 compliant. For applications requiring RoHS3 compliance, the ISL6121HIBZA is the appropriate selection. Both parts maintain REACH unaffected status and identical export classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the ISL6121HIBZA replace the ISL6121HIB in existing designs?

A: Yes. Both parts share identical supply voltage ranges (2.5V ~ 5.5V), operating temperature specifications (-40°C ~ 85°C), package configuration (8-SOIC), and functional application (Single Supply/Current Limiting Controller). Pin-to-pin compatibility and electrical performance are equivalent.

Q: What is the difference between ISL6121HIB and ISL6121HIBZA?

A: The primary difference is RoHS compliance status. The ISL6121HIB is RoHS non-compliant, while the ISL6121HIBZA is ROHS3 compliant. All other electrical, mechanical, and regulatory parameters are identical.

Q: Are there packaging differences between these part numbers?

A: Both parts use the same 8-SOIC package with 0.154" width and 3.90mm dimensions. The ISL6121HIBZA is supplied in tube packaging, while the ISL6121HIB packaging specification is not detailed. This does not affect electrical or mechanical compatibility.

Q: What is the Moisture Sensitivity Level for these components?

A: Both the ISL6121HIB and ISL6121HIBZA have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts still in production?

A: Both the ISL6121HIB and ISL6121HIBZA are classified as obsolete products. Component selection should account for this status in long-term supply planning.
