BTS650P Equivalent & Substitute Parts

Part Overview

The BTS650P is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, classified as a Power Switch/Driver with 1:1 N-Channel configuration. This component operates as a high-side switch with a maximum output current of 55A and supports load voltages from 5V to 34V. The device is currently marked as Obsolete, necessitating identification of functionally equivalent substitute components for ongoing design requirements and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the BTS650P are identified based on strict electrical and mechanical compatibility criteria. The primary substitute, BTS500551TMBAKSA1, maintains functional equivalence through the following key parameters:

Electrical Compatibility Parameters:

• Output Configuration: High Side, N-Channel (identical)
• Ratio - Input:Output: 1:1 (identical)
• Voltage - Load: 5V ~ 34V (identical)
• Rds On (Typ): 4.4mOhm (identical)
• Operating Temperature: -40°C ~ 150°C (TJ) (identical)
• Interface: On/Off (identical)
• Input Type: Non-Inverting (identical)
• Fault Protection: Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage (identical)
• Features: Auto Restart (identical)

Mechanical Compatibility Parameters:

• Package / Case: TO-220-7 (identical form factor)
• Mounting Type: Through Hole (identical)

Performance Enhancement:

• Current - Output (Max): 70A (BTS500551TMBAKSA1) versus 55A (BTS650P) — the substitute provides higher current capacity, making it suitable for applications requiring equal or lower current specifications.

Parameter Comparison

Engineering Selection Recommendations

The BTS500551TMBAKSA1 serves as the direct substitute for the obsolete BTS650P based on electrical and mechanical parameter equivalence. Selection criteria are determined by product lifecycle status and regulatory compliance:

Product Status Consideration: The BTS650P is classified as Obsolete, indicating end-of-life status and unavailability for new procurement. The BTS500551TMBAKSA1 is designated Last Time Buy, indicating limited availability with a defined end-of-support window. Both components are manufactured by Infineon Technologies within the PROFET® series.

Regulatory Compliance: The BTS500551TMBAKSA1 carries RoHS3 Compliance certification, meeting current environmental and hazardous substance restrictions. Both components maintain REACH Unaffected status and are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Current Capacity: The substitute component provides 70A maximum output current compared to the original 55A specification. This enhanced capacity accommodates applications operating at or below the original 55A requirement without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can BTS500551TMBAKSA1 directly replace BTS650P in existing designs? A: Yes. Both components share identical electrical parameters (output configuration, voltage range, on-resistance, protection features, and operating temperature), identical package form factor (TO-220-7), and identical mounting type (Through Hole). The substitute's higher current rating (70A vs. 55A) does not prevent direct substitution for applications requiring 55A or less.

Q: What is the difference between TO-220-7 and TO-220-7 Formed Leads? A: Both designations refer to the same seven-pin TO-220 package form factor. The "Formed Leads" specification indicates the leads have been pre-formed for insertion into PCB holes. This is a manufacturing variation that does not affect electrical compatibility or mechanical fit in standard through-hole applications.

Q: Why is the BTS650P marked as Obsolete? A: Obsolete status indicates the component has reached end-of-life and is no longer manufactured or supported by Infineon Technologies. The BTS500551TMBAKSA1, designated Last Time Buy, represents the available alternative within the same product family.

Q: Are there any thermal or performance differences between these components? A: Both components operate across the identical temperature range (-40°C to 150°C junction temperature) and maintain the same on-resistance specification (4.4mOhm typical). The substitute's higher current capacity does not introduce thermal or performance penalties for applications within the original 55A specification.

Q: What is the MSL (Moisture Sensitivity Level) for these components? A: Both the BTS650P and BTS500551TMBAKSA1 carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Is the BTS500551TMBAKSA1 available in the same packaging format? A: The BTS650P was supplied in bulk inventory format, while BTS500551TMBAKSA1 is supplied in Tube packaging. Both use identical through-hole TO-220-7 package form factors suitable for standard PCB assembly processes.
