BTS824R Equivalent & Substitute Parts

Part Overview

The BTS824R is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, specifically a Power Switch/Driver with 1:1 N-Channel configuration rated at 3.7A maximum output current. This component operates as a general-purpose high-side switch with on/off interface control, designed for load switching applications in the 5.5V to 40V range.

The BTS824R is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BTS824R is determined by the following critical parameters:

• Electrical Compatibility: Identical output configuration (high-side N-channel), matching load voltage range (5.5V ~ 40V), and equivalent or superior maximum output current rating (≥3.7A)
• Functional Equivalence: Four outputs with 1:1 ratio, on/off interface control, and identical fault protection features (current limiting, open load detect, over temperature, over voltage)
• Thermal Performance: Operating temperature range of -40°C ~ 150°C (TJ)
• Package Compatibility: Surface mount technology with compatible pinout and form factor

The BTS724GXUMA1 meets all substitution criteria as a direct equivalent from the same manufacturer with enhanced product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The BTS724GXUMA1 is the manufacturer-recommended substitute for the obsolete BTS824R. Selection of this substitute is supported by the following engineering factors:

Product Status: The BTS724GXUMA1 maintains active product status with ongoing manufacturer support, ensuring long-term availability and supply chain continuity compared to the obsolete BTS824R.

Compliance and Certifications: The BTS724GXUMA1 is ROHS3 compliant and carries AEC-Q100 automotive qualification, providing enhanced regulatory compliance and quality assurance compared to the non-compliant BTS824R.

Electrical Equivalence: Both components share identical load voltage range (5.5V ~ 40V), output configuration (high-side N-channel), on/off interface, and fault protection features. The BTS724GXUMA1 output current rating of 3A is lower than the BTS824R's 3.7A; applications requiring the full 3.7A specification must evaluate current margin requirements.

Thermal and Mechanical Compatibility: Identical operating temperature range (-40°C ~ 150°C TJ) and surface mount technology ensure thermal and mechanical compatibility. Package form factors differ slightly (20-SOIC vs. 20-PowerSOIC); PCB layout verification is required to confirm physical fit.

Frequently Asked Questions (FAQ)

Q: Can the BTS724GXUMA1 directly replace the BTS824R in existing designs?

A: The BTS724GXUMA1 provides electrical and functional equivalence for applications operating at or below 3A output current. Applications requiring the full 3.7A specification of the BTS824R must evaluate whether the 3A rating of the BTS724GXUMA1 meets system requirements. Package form factor differences (20-SOIC vs. 20-PowerSOIC) require PCB layout verification.

Q: What are the key differences between these two parts?

A: The primary differences are product status (BTS824R is obsolete; BTS724GXUMA1 is active), maximum output current (3.7A vs. 3A), RoHS compliance status (non-compliant vs. ROHS3 compliant), and package form factor (20-PowerSOIC vs. 20-SOIC). Electrical specifications for load voltage, output configuration, and fault protection are identical.

Q: Are there any package compatibility concerns?

A: Yes. The BTS824R uses a 20-PowerSOIC package (0.433", 11.00mm width), while the BTS724GXUMA1 uses a 20-SOIC package (0.295", 7.50mm width). Although both are surface mount 20-pin packages, the physical dimensions differ. PCB footprint and layout must be verified for compatibility before implementation.

Q: Does the lower current rating of the BTS724GXUMA1 affect substitution suitability?

A: The BTS724GXUMA1 maximum output current is 3A compared to the BTS824R's 3.7A. For applications operating below 3A, this difference is not a limiting factor. Applications requiring sustained operation above 3A must evaluate whether the reduced current margin is acceptable for the intended application.

Q: What compliance advantages does the BTS724GXUMA1 offer?

A: The BTS724GXUMA1 is ROHS3 compliant and carries AEC-Q100 automotive qualification, whereas the BTS824R is RoHS non-compliant. These certifications provide regulatory compliance for restricted substance use and automotive-grade quality assurance.
