RT8011GF Equivalent & Substitute Parts

Part Overview

The RT8011GF is an active buck switching regulator IC manufactured by Richtek USA Inc., designed for positive adjustable output voltage regulation with 2A output current capability. This component operates across a 2.6V to 5.5V input range and delivers adjustable output from 0.8V to 5V, making it suitable for portable power applications and embedded systems requiring step-down voltage conversion. The device is currently in active production status with 903 units in stock. Equivalent parts are identified when design requirements necessitate alternative sourcing, inventory constraints, or specific performance characteristics aligned with the original specification parameters.

Engineering Selection Recommendations

The EL7532IYZ qualifies as a direct substitute for the RT8011GF based on functional equivalence and regulatory compliance alignment. Both devices maintain identical output current capacity (2A), operating temperature range (-40°C to 85°C), package form factor (10-MSOP), and regulatory certifications (ROHS3, EAR99, REACH unaffected). The EL7532IYZ provides expanded input voltage tolerance (2.5V minimum versus 2.6V) and higher maximum output voltage capability (5.5V versus 5V), making it suitable for applications requiring the RT8011GF specifications. Both components feature integrated synchronous rectification and adjustable output voltage architecture. Selection between these parts should be based on availability, lead time, and cost considerations, as electrical performance parameters remain equivalent within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the EL7532IYZ replace the RT8011GF in existing designs?

A: Yes. The EL7532IYZ is electrically and mechanically compatible with the RT8011GF. Both devices share identical package geometry (10-MSOP), output current rating (2A), operating temperature range (-40°C to 85°C), and adjustable output voltage architecture. The EL7532IYZ input voltage range (2.5V–5.5V) fully encompasses the RT8011GF specification (2.6V–5.5V), and its maximum output voltage (5.5V) exceeds the RT8011GF (5V).

Q: Are there package compatibility concerns?

A: No. Both the RT8011GF and EL7532IYZ use the 10-TFSOP/10-MSOP package with 0.118" (3.00mm) width. Pin configuration and footprint are identical, allowing direct PCB substitution without layout modifications.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (Richtek versus Renesas), switching frequency specification (RT8011GF: 300kHz–4MHz; EL7532IYZ: 1.5MHz fixed), and moisture sensitivity level (RT8011GF: MSL 3; EL7532IYZ: MSL 2). The EL7532IYZ provides lower minimum input voltage (2.5V) and higher maximum output voltage (5.5V) compared to the RT8011GF.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RT8011GF and EL7532IYZ are ROHS3 compliant, classified as EAR99, and REACH unaffected. They meet identical environmental and export compliance standards.

Q: Which part should be selected for new designs?

A: Selection should be based on component availability, supply chain lead times, and cost. From a technical standpoint, both parts satisfy identical functional requirements for buck regulation applications requiring 2A output current and adjustable voltage output in the 0.8V–5V range.
