ISL62381HRTZ Equivalent & Substitute Parts

Part Overview

The ISL62381HRTZ is a Power Supply Controller manufactured by Renesas Electronics Corporation in a 32-TQFN (5x5) surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system designs and production requirements. The ISL62381HRTZ operates with a supply voltage range of 5.5V to 25V and is designed for power supply control applications requiring a 32-pin thermally enhanced quad flat no-lead package.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL62381HRTZ are evaluated based on the following critical parameters:

• Category: Power Management (PMIC) classification
• Mounting Type: Surface Mount technology
• RoHS Compliance: ROHS3 Compliant status
• Supply Voltage Range: Operational voltage compatibility
• Package Type: Physical form factor and pin count considerations
• Current Supply Rating: Quiescent current specifications
• Operating Temperature Range: Thermal operating envelope

The identified substitute parts operate within compatible electrical specifications and regulatory compliance frameworks, though package configurations and voltage supply ranges may differ based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

ADM1041AARQZ-REEL is an active product from Analog Devices Inc. with ROHS3 compliance and superior moisture sensitivity characteristics (MSL 1). However, this part operates at a reduced supply voltage range of 4.5V to 5.5V, which is narrower than the ISL62381HRTZ specification of 5.5V to 25V. This substitute is suitable only for applications operating within the lower voltage envelope.

TEA1716T/1,518 is an active product from NXP USA Inc. with ROHS3 compliance and an extended operating temperature range of -40°C to 150°C. This part is designed for PFC (Power Factor Correction) applications with a discontinuous conduction mode and operates on AC input voltage (70 ~ 276 VAC). This substitute is applicable only to AC-input power supply designs and is not compatible with DC-input applications requiring the ISL62381HRTZ voltage range.

Both substitute parts maintain regulatory compliance through ROHS3 certification and REACH unaffected status, matching the ISL62381HRTZ compliance profile.

Frequently Asked Questions (FAQ)

Q: Can ADM1041AARQZ-REEL directly replace ISL62381HRTZ in all applications?

A: No. The ADM1041AARQZ-REEL operates at 4.5V to 5.5V supply voltage, while the ISL62381HRTZ supports 5.5V to 25V. Substitution is limited to applications operating within the 4.5V to 5.5V range. Additionally, the package differs: ADM1041AARQZ-REEL uses 24-SSOP versus the 32-WFQFN of the ISL62381HRTZ.

Q: Is TEA1716T/1,518 suitable for DC power supply applications?

A: No. The TEA1716T/1,518 is designed for AC input PFC applications (70 ~ 276 VAC) and operates in discontinuous conduction mode. It is not compatible with DC-input power supply designs that require the ISL62381HRTZ.

Q: What are the key differences in package configuration?

A: The ISL62381HRTZ uses a 32-pin WFQFN package with exposed pad. The ADM1041AARQZ-REEL uses a 24-pin SSOP package, and the TEA1716T/1,518 uses a 24-pin SOIC package. These differences require PCB layout modifications and are not pin-compatible.

Q: Are all three parts RoHS compliant?

A: Yes. The ISL62381HRTZ, ADM1041AARQZ-REEL, and TEA1716T/1,518 are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the significance of product status (Obsolete vs. Active)?

A: The ISL62381HRTZ is obsolete, meaning it is no longer manufactured. The ADM1041AARQZ-REEL and TEA1716T/1,518 are active products with ongoing availability and manufacturing support, making them more suitable for new designs and long-term production.

Q: How do moisture sensitivity levels affect component handling?

A: The ISL62381HRTZ and TEA1716T/1,518 have MSL 3 (168 hours), requiring controlled storage and handling. The ADM1041AARQZ-REEL has MSL 1 (unlimited), allowing more flexible storage conditions without moisture bake-out requirements.
