RT9801BGE Equivalent & Substitute Parts

Part Overview

The RT9801BGE is an active low reset supervisor integrated circuit designed for power management applications. This single-channel supervisor monitors voltage levels and provides open drain or open collector output for system reset control. The device operates across an industrial temperature range of -40°C to 125°C and is housed in a compact SOT-23-6 surface mount package. As an Active product status component with ROHS3 compliance, the RT9801BGE serves critical power sequencing and fault detection functions in embedded systems and industrial equipment. Substitute parts are identified when equivalent electrical characteristics, package specifications, and functional parameters align with the original design requirements.

Substitute Part Grouping Explanation

Substitute parts for the RT9801BGE are identified based on strict parameter equivalence across the following critical criteria:

Electrical Equivalence: Single-channel voltage monitoring, adjustable/selectable threshold configuration, active low reset output via open drain or open collector topology, and 120ms minimum reset timeout.

Package Compatibility: SOT-23-6 surface mount package ensures mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Functional Classification: Simple reset/power-on reset supervisor type with identical monitoring and output characteristics.

Environmental & Compliance Alignment: Operating temperature range of -40°C to 125°C, ROHS3 compliance, MSL 3 rating, and REACH unaffected status ensure regulatory and reliability equivalence.

Manufacturer Consistency: Parts sourced from Richtek USA Inc. maintain design consistency and supply chain reliability.

The RT9801AGE meets all substitution criteria and is classified as a parametric equivalent to the RT9801BGE.

Parameter Comparison

Engineering Selection Recommendations

Both the RT9801BGE and RT9801AGE are Active product status components manufactured by Richtek USA Inc. with identical electrical specifications, package configurations, and compliance certifications. Selection between these parts may be based on inventory availability and supply chain considerations. The RT9801AGE currently maintains higher inventory levels (20,400 pcs) compared to the RT9801BGE (3,164 pcs), making it suitable for high-volume production requirements. Both parts satisfy ROHS3 compliance and REACH regulatory requirements, ensuring compatibility with modern manufacturing and environmental standards. The SOT-23-6 package and identical thermal characteristics ensure direct substitution without PCB redesign or thermal management modifications.

Frequently Asked Questions (FAQ)

Q: Can the RT9801AGE directly replace the RT9801BGE in existing designs?

A: Yes. Both parts share identical electrical specifications, package type (SOT-23-6), reset characteristics (active low, 120ms minimum timeout), and operating temperature range (-40°C to 125°C). Direct substitution is supported without circuit modifications.

Q: Are there differences in voltage threshold adjustment between these parts?

A: No. Both the RT9801BGE and RT9801AGE feature adjustable/selectable voltage thresholds. Threshold configuration methods and external component requirements are equivalent.

Q: What is the significance of the SOT-23-6 package for substitution?

A: The SOT-23-6 package is a standard six-pin surface mount package. Both substitute parts use this identical package, ensuring mechanical compatibility with existing PCB layouts, solder reflow profiles, and assembly equipment without modification.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 3 rating with 168-hour floor life. Storage, handling, and reflow procedures are identical for both components.

Q: Are there compliance or certification differences between RT9801BGE and RT9801AGE?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Regulatory and environmental compliance is equivalent.

Q: Which part should be selected for new production designs?

A: Selection should be based on supply chain availability and inventory levels. The RT9801AGE offers higher current inventory availability. Both parts are Active status and suitable for new designs without technical differentiation.
