BTS4880RNT Equivalent & Substitute Parts

Part Overview

The BTS4880RNT is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, functioning as a Power Switch/Driver with 1:1 N-Channel configuration rated for 625mA output. This component operates as a high-side N-channel switch with 8 outputs, designed for automotive applications with AEC-Q100 qualification. The BTS4880RNT is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure long-term component availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution of the BTS4880RNT is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Identical output configuration (8 N-channel high-side switches), load voltage range (11V ~ 45V), maximum output current (625mA), and on-resistance (150mOhm typical)
• Functional Features: Matching control interface (On/Off, Non-Inverting), fault protection mechanisms (Current Limiting Fixed, Over Temperature, Over Voltage), and status flag capability
• Package Compatibility: Identical 36-BSSOP package with exposed pad and surface mount technology
• Operating Range: Identical junction temperature range (-25°C ~ 125°C)
• Manufacturer Consistency: Same manufacturer (Infineon Technologies) ensures design continuity and documentation alignment

The BTS4880RAUMA1 meets all substitution criteria as an active product variant within the same base product family (BTS4880).

Engineering Selection Recommendations

The BTS4880RAUMA1 is the direct functional equivalent for BTS4880RNT replacement. Selection is based on the following engineering criteria:

Product Status: The BTS4880RAUMA1 maintains active product status with current manufacturing support, whereas the BTS4880RNT is obsolete. This ensures long-term availability and supply chain continuity.

Compliance & Certification: The BTS4880RAUMA1 carries ROHS3 compliance certification and maintains REACH unaffected status, meeting current regulatory requirements for new designs and production environments.

Electrical & Functional Equivalence: All critical electrical parameters, output configuration, protection mechanisms, and operating ranges are identical between the two parts, enabling direct substitution without circuit redesign.

Package & Mounting Compatibility: Identical 36-BSSOP package specifications and surface mount technology ensure PCB layout compatibility and manufacturing process alignment.

Frequently Asked Questions (FAQ)

Q: Can BTS4880RAUMA1 be used as a direct replacement for BTS4880RNT in existing designs?

A: Yes. The BTS4880RAUMA1 is electrically and functionally equivalent across all specified parameters. No circuit modifications are required for substitution. PCB layout and assembly processes remain unchanged due to identical packaging.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. BTS4880RNT is obsolete, while BTS4880RAUMA1 is active. The BTS4880RAUMA1 is part of the miniPROFET® series and includes ROHS3 compliance. All electrical specifications and package dimensions are identical.

Q: Are there any moisture sensitivity differences?

A: Yes. BTS4880RNT has MSL 1 (Unlimited), while BTS4880RAUMA1 has MSL 3 (168 Hours). This affects storage and handling requirements. BTS4880RAUMA1 requires controlled moisture exposure during storage and must be baked before reflow soldering if moisture absorption limits are exceeded.

Q: Is the BTS4880RAUMA1 suitable for automotive applications?

A: The BTS4880RNT carries AEC-Q100 automotive qualification. The BTS4880RAUMA1 specifications do not explicitly list AEC-Q100 in the provided parameters. Verify automotive qualification status with Infineon Technologies if AEC-Q100 certification is a design requirement.

Q: What packaging options are available for BTS4880RAUMA1?

A: BTS4880RAUMA1 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Both formats use the identical 36-BSSOP package with exposed pad for surface mount assembly.
