ISL6255AHAZ Equivalent & Substitute Parts

Part Overview

The ISL6255AHAZ is a lithium-ion/polymer battery charger IC designed for 2–4 cell battery pack applications. Manufactured by Renesas Electronics Corporation, this component integrates constant-current/constant-voltage charging control with integrated fault protection for over-temperature and short-circuit conditions. The ISL6255AHAZ is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL6255AHAZ is determined by strict equivalence across the following parameters:

• Battery chemistry and cell count (Lithium Ion/Polymer, 2–4 cells)
• Maximum charge current rating (2.6A)
• Maximum battery pack voltage (17.64V)
• Maximum supply voltage (25V)
• Charging control method (Constant - Programmable)
• Integrated fault protection (Over Temperature, Short Circuit)
• Operating temperature range (-10°C ~ 100°C)
• Package and pinout compatibility (28-SSOP)
• Surface mount capability

The ISL6255HAZ meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ISL6255HAZ is the direct parametric equivalent for the obsolete ISL6255AHAZ. Both parts share identical electrical specifications, package geometry, and functional characteristics across all critical parameters. The ISL6255HAZ is currently in active production status, ensuring availability for new designs and production continuity.

Selection of the ISL6255HAZ is appropriate for applications requiring direct replacement of the ISL6255AHAZ without circuit modification. Both parts comply with export control classification EAR99 and are subject to identical tariff codes (HTSUS 8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can the ISL6255HAZ be used as a direct replacement for the ISL6255AHAZ?

A: Yes. The ISL6255HAZ is a parametric equivalent with identical electrical ratings, charge current capability (2.6A maximum), battery pack voltage handling (17.64V maximum), and 28-SSOP package pinout. No circuit redesign is required.

Q: What is the primary advantage of switching to the ISL6255HAZ?

A: The ISL6255HAZ is in active production status, whereas the ISL6255AHAZ is obsolete. This ensures long-term component availability and supply chain stability.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the 28-SSOP surface mount package with identical dimensions (0.154" width, 3.90mm). PCB layout and assembly processes remain unchanged.

Q: Do both parts support the same battery chemistry and cell configurations?

A: Yes. Both the ISL6255AHAZ and ISL6255HAZ are rated for lithium-ion/polymer battery packs with 2–4 cell configurations and identical charging control methods.

Q: Are there compliance or certification differences?

A: The ISL6255AHAZ is specified as ROHS3 compliant. The ISL6255HAZ compliance status is not specified in the provided data. Both parts carry identical export control (EAR99) and tariff classifications.
