Equivalent & Substitute Parts for IPS041LTR

Part Overview

The IPS041LTR is a Power Switch/Driver IC manufactured by Infineon Technologies, configured as a 1:1 N-Channel low-side switch in SOT-223 packaging. This device delivers 750mA maximum output current with 370mOhm on-resistance and operates across -40°C to 150°C. The product is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IPS041LTR is determined by the following mandatory parameters:

• Functional Configuration: 1:1 ratio, N-Channel, low-side output topology
• Interface Type: On/Off control, non-inverting input
• Electrical Compatibility: Maximum load voltage ≥35V, maximum output current ≥750mA
• Package Compatibility: SOT-223 form factor (TO-261-4, TO-261AA)
• Operating Temperature: -40°C to 150°C range
• Fault Protection: Current limiting and over-temperature protection minimum

All four substitute parts meet these core substitution criteria. The substitutes are grouped by electrical performance tier: BSP77E6433HUMA1 and BTS3118NHUMA1 offer enhanced current handling (2.17A) with lower on-resistance (70mOhm), while BTS3110NHUMA1 provides intermediate performance (1.4A, 150mOhm), and BSP75GTA delivers higher voltage rating (60V) with moderate current (1.6A, 550mOhm).

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: All four substitute parts (BSP77E6433HUMA1, BTS3110NHUMA1, BTS3118NHUMA1, BSP75GTA) are ROHS3 compliant, whereas the IPS041LTR is non-compliant. Selection of any substitute satisfies modern regulatory requirements.

For Active Product Status: All substitutes carry active product status, ensuring long-term availability and manufacturing support. The obsolete status of IPS041LTR necessitates migration to one of these active alternatives.

For Equivalent Current Handling: BSP77E6433HUMA1 and BTS3118NHUMA1 provide 2.17A capability, exceeding the original 750mA specification with superior on-resistance (70mOhm vs. 370mOhm). BTS3110NHUMA1 delivers 1.4A with 150mOhm on-resistance. BSP75GTA provides 1.6A with 550mOhm on-resistance but offers the highest voltage rating (60V).

For Voltage Margin: BSP77E6433HUMA1, BTS3110NHUMA1, and BTS3118NHUMA1 support 42V maximum load voltage, providing 7V margin above the original 35V specification. BSP75GTA supports 60V, offering maximum voltage headroom.

For Enhanced Protection: All substitutes include over-voltage protection in addition to current limiting and over-temperature protection, providing superior fault coverage compared to the original device.

Frequently Asked Questions (FAQ)

Q: Can IPS041LTR be directly replaced with any of these substitutes?

A: Yes, all four parts maintain the required 1:1 N-Channel low-side configuration, SOT-223 package compatibility, and -40°C to 150°C operating range. Electrical parameters of all substitutes exceed or match the original specification, ensuring functional compatibility in existing circuit designs.

Q: What is the primary reason for substitution?

A: The IPS041LTR is classified as obsolete. All substitute parts carry active product status, ensuring continued manufacturing availability and supply chain reliability.

Q: Do the substitutes require PCB layout modifications?

A: No. All substitutes use SOT-223 packaging (TO-261-4, TO-261AA form factor), maintaining identical footprint compatibility with the original IPS041LTR design.

Q: Which substitute offers the best performance improvement?

A: BSP77E6433HUMA1 and BTS3118NHUMA1 both deliver 2.17A maximum current with 70mOhm on-resistance, representing significant improvements over the original 750mA/370mOhm specification. Both are Infineon HITFET® series devices with active status.

Q: Are there compliance differences between substitutes?

A: All substitutes are ROHS3 compliant. The original IPS041LTR is RoHS non-compliant. For applications requiring RoHS compliance, any substitute satisfies regulatory requirements.

Q: What is the difference between BSP77E6433HUMA1 and BTS3118NHUMA1?

A: Both parts are electrically identical (2.17A, 70mOhm, 42V) and belong to the Infineon HITFET® series. The primary difference is packaging: BSP77E6433HUMA1 is supplied in Cut Tape (CT) & Digi-Reel®, while BTS3118NHUMA1 is supplied in Tape & Reel (TR). BTS3118NHUMA1 has higher inventory availability (12,870 pcs vs. 3,400 pcs).

Q: When should BSP75GTA be selected over Infineon alternatives?

A: BSP75GTA is the appropriate choice when maximum load voltage exceeds 42V, as it supports 60V operation. It is manufactured by Diodes Incorporated under the INTELLIFET® series and includes auto-restart functionality. Select this part for high-voltage applications requiring voltage ratings beyond 42V.

Q: Do all substitutes support the same fault protection features?

A: All substitutes include current limiting (fixed), over-temperature, and over-voltage protection. The original IPS041LTR includes only current limiting and over-temperature protection, making substitutes superior in fault coverage.
