IPS1031RTRLPBF Equivalent & Substitute Parts

Part Overview

The IPS1031RTRLPBF is a Power Switch/Driver N-Channel 1:1 low-side switch manufactured by Infineon Technologies in TO-252AA (DPAK) packaging. This component is rated for 3A maximum output current at 28V load voltage with 40mOhm typical on-resistance. The part is currently obsolete, making equivalent and substitute components necessary for ongoing design support and production continuity. Substitute parts maintain the same functional topology (1:1 N-Channel low-side configuration) while offering enhanced electrical performance and active product status from Infineon and STMicroelectronics.

Engineering Selection Recommendations

Primary Recommendation: BTS134DATMA1 This Infineon HITFET® part meets all mandatory compatibility requirements with superior electrical performance. It provides 3.5A output current (exceeding the 3A requirement), 42V load voltage rating (exceeding 28V), and 35mOhm on-resistance (improving upon 40mOhm). The part carries active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Cut Tape & Digi-Reel® packaging supports both prototype and production volumes.

Secondary Recommendation: BTS3028SDLATMA1 For applications requiring higher current capacity or elevated voltage margins, this Infineon HITFET® part delivers 5A output current and 60V load voltage rating with 28mOhm on-resistance. Active product status and ROHS3 compliance ensure long-term availability and regulatory compliance.

Alternative Sourcing: VND14NV04TR-E This STMicroelectronics OMNIFET II™ part provides significant current headroom (12A) with 36V load voltage and 35mOhm maximum on-resistance. Active product status and ROHS3 compliance support design flexibility. Note: MSL 3 (168 Hours) requires controlled moisture handling during storage and assembly.

Not Recommended: VND5N07-E This part carries Last Time Buy status, limiting long-term availability for production designs.

Frequently Asked Questions (FAQ)

Q: Can BTS118DATMA1 replace IPS1031RTRLPBF directly? BTS118DATMA1 meets all package and functional requirements but provides only 2.4A output current, which is below the original 3A specification. Use only if your application current requirement is ≤ 2.4A.

Q: What is the difference between BTS142DATMA1 and BTS3142DATMA1? Both parts share identical electrical specifications (4.6A, 42V, 23mOhm). BTS142DATMA1 is packaged in Tape & Reel format; BTS3142DATMA1 is also Tape & Reel. Both are active products suitable for production use.

Q: Why do STMicroelectronics parts show higher on-resistance values? VND series parts specify maximum on-resistance (Rds On Max) rather than typical values. VND14NV04TR-E at 35mOhm (Max) is equivalent to BTS134DATMA1 at 35mOhm (Typ). Verify datasheet specifications for your thermal and performance requirements.

Q: Are all substitute parts RoHS compliant? All Infineon HITFET® parts (BTS series) carry ROHS3 compliance. STMicroelectronics OMNIFET™ parts (VND series) also carry ROHS3 compliance. The original IPS1031RTRLPBF does not specify RoHS status.

Q: What packaging options are available? Infineon parts are available in Cut Tape & Digi-Reel® or Tape & Reel formats. STMicroelectronics parts are available in Cut Tape & Digi-Reel® (VND3NV04TR-E, VND10N06TR-E, VND14NV04TR-E, VND5N07TR-E) or Tube (VND5N07-E). Select based on production volume and assembly requirements.

Q: Can I use VND10N06TR-E if load voltage is not specified in the datasheet? VND10N06TR-E does not specify maximum load voltage in the provided data. Use only if your application voltage is within the safe operating area of comparable parts (36V–42V minimum). Consult the full datasheet for complete electrical ratings.

Q: What is the moisture sensitivity impact of MSL 3 parts? VND series parts with MSL 3 (168 Hours) require storage at ≤ 30°C and ≤ 85% relative humidity. Parts must be used within 168 hours of bag opening. Infineon parts with MSL 1 (Unlimited) have no moisture sensitivity restrictions. Select MSL 1 parts for simplified supply chain management.
