EL7586AILZ Equivalent & Substitute Parts

Part Overview

The EL7586AILZ is a TFT LCD voltage converter IC manufactured by Renesas Electronics Corporation, designed for multi-output power management applications. This device features 4 independent outputs with input voltage range of 3V to 5V and output voltage capability from 5.5V to 20V. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL7586AILZ is determined by the following critical parameters:

• Input Voltage Range: The substitute must accept 3V to 5V input
• Output Voltage Range: The substitute must support output voltages between 5.5V and 20V
• Number of Outputs: The EL7586AILZ provides 4 independent outputs; substitutes must match this configuration
• Operating Temperature Range: -40°C to 85°C compatibility is required
• Mounting Type: Surface mount technology is mandatory
• Compliance Standards: RoHS3 compliance and MSL 3 rating are required

The ISL97519AIUZ-T is identified as a substitute component. However, this part exhibits significant functional differences: it is a single-output boost regulator with adjustable output (5V to 25V), whereas the EL7586AILZ is a multi-output converter. The ISL97519AIUZ-T shares common manufacturer origin, compliance certifications, and operating temperature range, but does not provide equivalent output configuration.

Parameter Comparison

Engineering Selection Recommendations

The ISL97519AIUZ-T maintains compliance with RoHS3 standards and MSL 3 moisture sensitivity requirements, matching the EL7586AILZ in these critical certifications. Both components operate across the -40°C to 85°C temperature range and are manufactured by Renesas Electronics Corporation.

However, direct functional substitution is not supported due to fundamental architectural differences. The EL7586AILZ is a multi-output converter with 4 independent outputs, while the ISL97519AIUZ-T is a single-output boost regulator. The input voltage range of the ISL97519AIUZ-T (2.3V minimum) extends below the EL7586AILZ specification (3V minimum), and the maximum output voltage capability (25V) exceeds the EL7586AILZ maximum (20V).

Selection of the ISL97519AIUZ-T requires circuit redesign to accommodate single-output operation and adjustable output configuration. Applications requiring the original 4-output architecture must pursue alternative multi-output converter solutions from the active product portfolio.

Frequently Asked Questions (FAQ)

Q: Can the ISL97519AIUZ-T directly replace the EL7586AILZ in existing designs?

A: No. The ISL97519AIUZ-T provides single adjustable output, whereas the EL7586AILZ provides 4 independent outputs. Circuit redesign is required.

Q: What are the key differences in output voltage capability?

A: The EL7586AILZ supports 5.5V to 20V output range. The ISL97519AIUZ-T supports 5V to 25V adjustable output. While the ranges overlap, the output configuration differs fundamentally.

Q: Are compliance certifications equivalent between these parts?

A: Yes. Both components are RoHS3 compliant with MSL 3 (168 Hours) moisture sensitivity rating and share identical operating temperature specifications.

Q: What is the package difference between these components?

A: The EL7586AILZ uses 20-VFQFN Exposed Pad packaging. The ISL97519AIUZ-T uses 8-TSSOP or 8-MSOP packaging. PCB layout and footprint modifications are required.

Q: Why is the EL7586AILZ listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active alternatives must be evaluated for new designs or production continuity.

Q: Can multiple ISL97519AIUZ-T devices be used to replace the 4-output configuration?

A: Potentially, but this requires significant circuit redesign, additional board space, and engineering validation. Each ISL97519AIUZ-T would provide only one output channel.
