RT9801AGE Equivalent & Substitute Parts

Part Overview

The RT9801AGE is an active low reset supervisor integrated circuit designed for power management applications. Manufactured by Richtek USA Inc., this component monitors a single voltage channel and provides open drain or open collector output for system reset control. The device is classified as a Simple Reset/Power-On Reset supervisor with a 120ms minimum reset timeout. Currently in active product status with 20,400 units in stock, the RT9801AGE serves critical functions in power supply monitoring and system initialization circuits. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and alternative sourcing options when the primary component becomes unavailable or when design requirements necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

The RT9801AGE belongs to the Richtek RT9801 supervisor family. Substitute parts within this family are determined by strict equivalence across the following critical parameters:

• Single voltage channel monitoring capability
• Adjustable/Selectable voltage threshold functionality
• Open drain or open collector output configuration
• Active low reset logic
• 120ms minimum reset timeout specification
• SOT-23-6 surface mount package
• Operating temperature range of -40°C to 125°C
• ROHS3 compliance and REACH unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in inventory levels, packaging format (Cut Tape vs. Digi-Reel), or manufacturing date codes do not affect substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT9801AGE and RT9801BGE are active product variants from Richtek USA Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability and inventory levels at the time of procurement
• Packaging format requirements (Cut Tape or Digi-Reel)
• Supply chain lead times and logistics considerations
• Cost differential, if applicable

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for industrial and commercial applications. The identical operating temperature range, package type, and functional specifications guarantee direct interchangeability in circuit designs without modification to PCB layouts or firmware configurations.

Frequently Asked Questions (FAQ)

Q: Can RT9801BGE be used as a direct replacement for RT9801AGE?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, output configurations, reset timing, and package specifications. Direct substitution is possible without circuit redesign.

Q: Are there any differences in the SOT-23-6 package between these parts?

A: No. Both parts use the identical SOT-23-6 surface mount package with the same pin configuration, footprint, and mechanical dimensions. PCB layouts require no modification.

Q: Do both parts support adjustable voltage thresholds?

A: Yes. Both RT9801AGE and RT9801BGE feature adjustable/selectable voltage threshold capability, allowing threshold configuration through external resistor networks.

Q: What is the significance of the different part number suffixes (AGE vs. BGE)?

A: The suffix variation indicates different manufacturing batches or date codes from Richtek USA Inc. These designations do not reflect functional or electrical differences. Both variants meet identical specifications.

Q: Are both parts suitable for -40°C to 125°C operating environments?

A: Yes. Both parts are rated for the full -40°C to 125°C temperature range and maintain specified performance across this entire operating window.

Q: Do inventory levels affect substitution eligibility?

A: No. Inventory quantities do not determine substitution capability. The RT9801AGE (20,400 units) and RT9801BGE (3,164 units) are equivalent regardless of stock levels.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory standing for all applications.
