BTS441TSAKSA1 Equivalent & Substitute Parts

Part Overview

The BTS441TSAKSA1 is a Power Management IC (PMIC) functioning as a high-side N-channel power switch with 1:1 input-output ratio, rated for 17A maximum output current. Manufactured by Infineon Technologies under the PROFET® series, this component is designed for general-purpose switching applications with integrated fault protection including current limiting, over-temperature, and over-voltage protection.

The BTS441TSAKSA1 is classified as Obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BTS441TSAKSA1 is determined by electrical and mechanical compatibility based on the following criteria:

Electrical Parameters (Must Match):

• Output Type: N-Channel
• Output Configuration: High Side
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Voltage - Load: 4.75V ~ 43V
• Current - Output (Max): 17A
• Rds On (Typ): 15mOhm
• Operating Temperature: -40°C ~ 150°C (TJ)
• Fault Protection: Current Limiting (Fixed), Over Temperature, Over Voltage
• Interface: On/Off
• Input Type: Non-Inverting

Mechanical Parameters (May Vary):

• Package / Case: Different package options available
• Mounting Type: Through Hole or Surface Mount variants
• Supplier Device Package: Variant-specific designations

The BTS441TGATMA1 qualifies as a direct substitute based on identical electrical specifications. The primary difference is the package configuration: the substitute uses Surface Mount (TO-263-5) packaging instead of Through Hole (TO-220-5) mounting, and is supplied in Tape & Reel format rather than bulk inventory.

Parameter Comparison

Engineering Selection Recommendations

The BTS441TGATMA1 is the qualified substitute for the obsolete BTS441TSAKSA1. Selection between these parts is determined by PCB assembly requirements:

Use BTS441TGATMA1 when:

• Surface mount assembly capability is available
• Modern manufacturing processes are in use
• ROHS3 compliance is required
• Active product status and ongoing manufacturer support are necessary

Use BTS441TSAKSA1 when:

• Through-hole mounting is mandated by existing PCB design
• Legacy assembly processes are in place
• Existing inventory stock is available

Both parts share identical electrical specifications and fault protection characteristics, ensuring functional equivalence in circuit operation. The substitute maintains the same load voltage range (4.75V ~ 43V), maximum output current (17A), on-resistance (15mOhm), and operating temperature range (-40°C ~ 150°C).

Frequently Asked Questions (FAQ)

Q: Can BTS441TGATMA1 directly replace BTS441TSAKSA1 in existing designs?

A: Electrical substitution is direct. However, PCB layout modification is required due to package differences: BTS441TSAKSA1 uses TO-220-5 through-hole mounting, while BTS441TGATMA1 uses TO-263-5 surface-mount packaging. Pin configuration and electrical function are equivalent.

Q: What are the key differences between these parts?

A: The primary differences are packaging format and product status. BTS441TSAKSA1 is through-hole mounted and obsolete. BTS441TGATMA1 is surface-mount and active. All electrical parameters, including current rating, voltage range, on-resistance, and protection features, are identical.

Q: Is the BTS441TGATMA1 available in higher quantities?

A: Yes. BTS441TGATMA1 inventory is 5730 pieces in Tape & Reel format, compared to 686 pieces of BTS441TSAKSA1 in bulk. The substitute's active product status ensures continued availability from the manufacturer.

Q: Are there compliance differences between these parts?

A: BTS441TGATMA1 is ROHS3 compliant. Both parts are REACH Unaffected and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for both.

Q: What is the pin compatibility between TO-220-5 and TO-263-5 packages?

A: While both are 5-pin packages, physical layout differs. TO-220-5 is through-hole with vertical mounting; TO-263-5 (D2PAK) is surface-mount with horizontal orientation. Electrical pin function is equivalent, but PCB redesign is necessary for package conversion.
