RW1A020ZPT2R Equivalent & Substitute MOSFET Parts Reference

Part Overview

The RW1A020ZPT2R by Rohm Semiconductor is an obsolete P-Channel MOSFET with a 12 V drain-to-source voltage, 2A continuous drain current, and a maximum Rds On of 105mOhm at 2A, 4.5V. It is packaged in a 6-WEMT surface mount case and meets ROHS3 and REACH compliance with an MSL of 1. Due to its obsolescence, identifying alternative models is essential for both new designs and repair scenarios requiring the same electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitution is defined strictly by matching or exceeding these key MOSFET parameters: FET type (P-Channel), drain-to-source voltage (Vdss), continuous drain current (Id), maximum Rds On at the defined test conditions, threshold voltage (Vgs(th)), gate charge (Qg), maximum gate-source voltage (Vgs Max), input capacitance (Ciss), power dissipation, maximum operating temperature, surface-mount package compatibility, RoHS and REACH compliance, moisture sensitivity level, and confirmed product status (active or available). Only parts adhering to the provided parameters are listed as substitutes.

Engineering Selection Recommendations

RW1A020ZPT2R is obsolete. Substitute parts RV5A040APTCR1, RV5C040APTCR1, and RV2C014BCT2CL are ROHS3 compliant, REACH unaffected, and MSL 1 rated. Substitute parts are active and meet inventory criteria. Selection can be made based on matching compliance and product availability as per the provided parameters.

Frequently Asked Questions (FAQ)

Q1: What determines suitable substitution for RW1A020ZPT2R?
A1: Suitable substitutes must match or exceed critical parameters: FET type, drain-to-source voltage (Vdss), continuous drain current (Id), Rds On (Max) at the defined measurement points, threshold voltage, gate charge, maximum gate-source voltage, input capacitance, power dissipation, operating temperature range, mounting type, device package, RoHS/REACH status, and MSL.

Q2: Are the substitute parts offered in surface mount configurations?
A2: All listed substitutes (RV5A040APTCR1, RV5C040APTCR1, RV2C014BCT2CL) feature surface mount compatible packaging.

Q3: How important is compliance certification in selecting substitutes?
A3: All substitutes are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited), aligning with the original RW1A020ZPT2R specifications.

Q4: Can package type affect drop-in compatibility?
A4: Yes. Substitutes use different package types (DFN1616-8S, DFN1006-3 versus 6-WEMT). Mechanical footprint compatibility must be evaluated per the provided device package parameter.

Q5: Are all substitutes active and available?
A5: The substitutes listed have "Active" status and confirmed inventory. The original part RW1A020ZPT2R is obsolete.
