EL7563CREZ Equivalent & Substitute Parts

Part Overview

The EL7563CREZ is a buck switching regulator IC manufactured by Renesas Electronics Corporation, designed for positive adjustable output applications. This power management IC delivers 4A output current with adjustable voltage regulation from 1V to 2.5V, operating from a 3V to 3.6V input range. The device is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL7563CREZ is determined by the following critical parameters:

• Identical package and pinout: 28-TSSOP (0.173", 4.40mm Width) Exposed Pad
• Matching topology: Buck switching regulator with positive adjustable output
• Compatible output current rating: 4A
• Overlapping input voltage range: minimum 3V support
• Overlapping output voltage range: capability to regulate within or encompassing 1V to 2.5V
• Identical switching frequency range: 200kHz ~ 1MHz
• Synchronous rectifier architecture: Yes
• Matching operating temperature range: -40°C ~ 85°C (TA)
• Equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected

The EL7554IREZ meets these substitution criteria as a functionally equivalent alternative from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The EL7554IREZ is a direct substitute for the EL7563CREZ based on identical package geometry, pinout compatibility, and matching electrical specifications within the primary operating parameters. Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The EL7554IREZ provides extended input voltage range (3V to 6V versus 3V to 3.6V) and extended output voltage range (0.8V to 6V versus 1V to 2.5V), offering greater design flexibility for applications requiring the EL7563CREZ's core 1V to 2.5V output specification. The identical 4A output current, 200kHz to 1MHz switching frequency, and synchronous rectifier architecture ensure functional equivalence for existing circuit designs.

Both devices carry obsolete product status, indicating end-of-life classification from the manufacturer. Component selection should prioritize available inventory and lead time considerations when sourcing either part number.

Frequently Asked Questions (FAQ)

Q: Can the EL7554IREZ directly replace the EL7563CREZ in existing designs?

A: Yes. The EL7554IREZ shares identical package, pinout, output current rating, switching frequency, and operating temperature specifications. The extended input and output voltage ranges of the EL7554IREZ do not prevent substitution for applications designed within the EL7563CREZ's original 3V to 3.6V input and 1V to 2.5V output specifications.

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

A: No. Both the EL7563CREZ and EL7554IREZ use the 28-TSSOP (0.173", 4.40mm Width) Exposed Pad package with surface mount technology. PCB layout and footprint compatibility are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for component substitution.

Q: What is the significance of the extended voltage ranges in the EL7554IREZ?

A: The EL7554IREZ supports broader input (up to 6V) and output (0.8V to 6V) voltage ranges compared to the EL7563CREZ. For applications operating within the EL7563CREZ's original specifications, this extended capability does not affect compatibility. The substitute part remains functionally equivalent for the intended design parameters.

Q: Are both parts currently available for procurement?

A: Both the EL7563CREZ and EL7554IREZ are classified as obsolete products. Availability depends on remaining distributor inventory. Procurement decisions should account for current stock levels and lead time requirements.
