IRLMS2002TR N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRLMS2002TR is an N-Channel MOSFET manufactured by Infineon Technologies, designed for surface mount applications in the SOT-23-6 package. This device features a 20V drain-to-source voltage rating with 6.5A continuous drain current capability and is optimized for low on-resistance applications requiring compact form factors.

The IRLMS2002TR is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this component is specified in active production or field service applications.

Substitute Part Grouping Explanation

Substitution of the IRLMS2002TR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• FET Type: Must be N-Channel MOSFET
• Drain-to-Source Voltage (Vdss): Must equal or exceed 20 V
• Continuous Drain Current (Id): Must equal or exceed 6.5 A at 25°C
• On-Resistance (Rds On): Must not exceed 30 mOhm at specified gate voltage
• Gate Threshold Voltage (Vgs(th)): Must match 1.2 V @ 250 µA specification
• Gate Charge (Qg): Must not exceed 22 nC @ 5 V
• Input Capacitance (Ciss): Must not exceed 1310 pF @ 15 V

Mechanical Equivalence Criteria:

• Package Type: Must be SOT-23-6 (Micro6™)
• Mounting Type: Must be Surface Mount
• Pin configuration and footprint compatibility required

The IRLMS2002TRPBF meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: IRLMS2002TRPBF

The IRLMS2002TRPBF is the direct functional and mechanical equivalent of the IRLMS2002TR. All critical electrical parameters are identical, including voltage rating, current capacity, on-resistance, gate characteristics, and capacitance specifications. Both devices share the same SOT-23-6 package and surface mount configuration, ensuring pin-for-pin compatibility.

Compliance Advantage:

The IRLMS2002TRPBF carries Active product status and ROHS3 compliance certification, whereas the IRLMS2002TR is classified as Obsolete and RoHS non-compliant. For new designs or systems requiring regulatory compliance, the IRLMS2002TRPBF is the appropriate selection. For legacy system maintenance where the original part is specified, the IRLMS2002TRPBF provides equivalent electrical performance without design modification.

Supply Availability:

The IRLMS2002TRPBF is available in significantly higher inventory quantities (146,300 pieces) compared to the IRLMS2002TR (6,300 pieces), supporting both immediate procurement and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the IRLMS2002TRPBF be used as a direct replacement for the IRLMS2002TR in existing designs?

A: Yes. The IRLMS2002TRPBF is electrically and mechanically equivalent to the IRLMS2002TR. All critical parameters—voltage rating, current capacity, on-resistance, gate threshold voltage, gate charge, and input capacitance—are identical. The SOT-23-6 package and surface mount configuration are unchanged, enabling direct substitution without circuit modification.

Q: What is the difference between IRLMS2002TR and IRLMS2002TRPBF?

A: Both parts are manufactured by Infineon Technologies and share identical electrical specifications. The primary differences are: (1) IRLMS2002TRPBF is Active product status while IRLMS2002TR is Obsolete; (2) IRLMS2002TRPBF is ROHS3 compliant while IRLMS2002TR is RoHS non-compliant; (3) IRLMS2002TRPBF is available in higher inventory quantities. The "PBF" suffix indicates lead-free plating and RoHS compliance.

Q: Are there any thermal or operating temperature differences between these parts?

A: The IRLMS2002TRPBF specifies an operating temperature range of -55°C to 150°C (junction temperature). The IRLMS2002TR does not provide explicit operating temperature specification in the available data. Both devices are rated for 2W power dissipation at ambient temperature. Thermal performance is equivalent for applications within the specified operating range.

Q: What packaging options are available for these parts?

A: Both the IRLMS2002TR and IRLMS2002TRPBF are supplied in SOT-23-6 (Micro6™) surface mount packages. The IRLMS2002TRPBF is available in Tape & Reel (TR) packaging for automated assembly. No alternative package options are available for these specific part numbers.

Q: Is the IRLMS2002TRPBF suitable for new product designs?

A: Yes. The IRLMS2002TRPBF is classified as Active product status and carries ROHS3 compliance certification, making it appropriate for new designs. It provides the same electrical performance as the obsolete IRLMS2002TR with improved regulatory compliance and assured long-term availability.

Q: What is the base product number for these MOSFETs?

A: The base product number is IRLMS2002. Both the IRLMS2002TR and IRLMS2002TRPBF are variants of this base product, differentiated by packaging and compliance specifications.
