ISL9000IRFCZ Equivalent & Substitute Parts

Part Overview

The ISL9000IRFCZ is a linear voltage regulator IC from Renesas Electronics Corporation designed for power management applications. It provides dual positive fixed outputs at 1.8V and 2.5V with 300mA output current per channel, housed in a 10-DFN (3x3) surface mount package. The device integrates enable control, power-on reset functionality, and comprehensive protection features including over-current, over-temperature, and under-voltage lockout protection.

The ISL9000IRFCZ is classified as obsolete. Identifying equivalent substitute parts is essential for design continuity, procurement flexibility, and long-term product support when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the ISL9000IRFCZ is determined by strict alignment across the following critical parameters:

Output voltage configuration: Dual positive fixed outputs at 1.8V and 2.5V
Output current capability: 300mA per channel minimum
Maximum input voltage: 6.5V
Dropout voltage: 0.4V @ 300mA
Package type: 10-DFN (3x3) with exposed pad
Control and protection features: Enable, Power On Reset, Over Current, Over Temperature, and UVLO protection
Operating temperature range: -40°C ~ 85°C
Compliance standards: ROHS3 Compliant, REACH Unaffected

The ISL9000AIRFCZ meets all substitution criteria as a direct equivalent, with identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Engineering Selection Recommendations

The ISL9000AIRFCZ is a direct functional equivalent to the ISL9000IRFCZ. Both devices share identical electrical specifications, output voltage configuration, current ratings, protection features, and package geometry.

The ISL9000AIRFCZ holds active product status from Renesas Electronics Corporation, ensuring ongoing availability and manufacturer support. The ISL9000IRFCZ is classified as obsolete, making the ISL9000AIRFCZ the appropriate selection for new designs and ongoing production requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status. The ISL9000AIRFCZ carries a higher moisture sensitivity level (MSL 3, 168 hours) compared to the ISL9000IRFCZ (MSL 1, unlimited), which may require adjusted handling and storage protocols in high-humidity environments.

Frequently Asked Questions (FAQ)

Q: Can the ISL9000AIRFCZ directly replace the ISL9000IRFCZ in existing designs?

A: Yes. The ISL9000AIRFCZ is electrically and mechanically identical to the ISL9000IRFCZ. Both devices provide dual 1.8V and 2.5V outputs at 300mA per channel, operate across the same input voltage range (up to 6.5V), and are housed in the same 10-DFN (3x3) package with exposed pad. No circuit modifications are required.

Q: What is the significance of the product status difference?

A: The ISL9000IRFCZ is obsolete, indicating Renesas Electronics Corporation no longer manufactures or supports this part. The ISL9000AIRFCZ is active, meaning it remains in production with full manufacturer support, technical documentation, and long-term availability assurance.

Q: How does the moisture sensitivity level difference affect component handling?

A: The ISL9000IRFCZ (MSL 1) has unlimited moisture exposure tolerance. The ISL9000AIRFCZ (MSL 3) requires controlled storage conditions with a maximum of 168 hours exposure to 85°C and 85% relative humidity before soldering. Standard moisture-controlled storage and handling procedures are required for the ISL9000AIRFCZ.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the ISL9000IRFCZ and ISL9000AIRFCZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What packaging formats are available for the ISL9000AIRFCZ?

A: The ISL9000AIRFCZ is supplied in tube packaging, whereas the ISL9000IRFCZ packaging format is not specified in the provided data. Confirm packaging requirements with your procurement or supply chain team.
