Key Parameters

Substitute Part Grouping Explanation

Substitution is determined based on strict alignment of provided, allowed parameters, including FET type, technology, voltage rating (Vdss), continuous drain current (Id), Rds On at specified conditions, gate threshold voltage (Vgs(th)), gate charge (Qg), maximum gate-source voltage (Vgs), input capacitance (Ciss), power dissipation, operating temperature range, mounting method, package, RoHS, MSL, and REACH status. All substitute parts listed meet or are strictly specified in these key parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitutes listed are in Active product status and comply with RoHS3 and REACH requirements. Both APT37M100B2 and STW22N95K5 have an MSL rating of 1 (Unlimited). The mounting type and package (TO-247-3 or variant) are common to both, ensuring direct mechanical compatibility.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine equivalence between APT37M100B2 and substitute MOSFETs?
A1: Substitution is determined by strict alignment of FET type, technology, drain-source voltage rating, continuous drain current, Rds On, gate threshold voltage, gate charge, maximum gate-source voltage, input capacitance, power dissipation, operating temperature, mounting type, package type, and compliance parameters.

Q2: Are the package types compatible for physical board mounting?
A2: APT37M100B2 uses a TO-247-3 Variant (T-MAX™ [B2]) package while STW22N95K5 uses a TO-247-3 package. Both are through-hole packages in the TO-247-3 form factor.

Q3: Are all substitute parts compliant with environmental and safety standards?
A3: All listed parts are ROHS3 Compliant, REACH Unaffected, and have an MSL of 1 (Unlimited).

Q4: Does the substitute maintain key parameters for high-power switching applications?
A4: Substitute parts are grouped by primary electrical and thermal ratings, mounting, and package. All shared parameters are listed in the comparison table.

Q5: Is further compatibility required beyond the specified parameters?
A5: Substitution is based solely on parameters explicitly provided. Only those parameters are considered in compatibility.
