Engineering Selection Recommendations

TIP41C-S is classified as obsolete. All recommended substitute parts possess active status and comply with ROHS3 where specified. Substitute parts matching the original device's electrical parameters and mechanical package, including TO-220-3, are suitable for direct replacement in designs requiring equivalent regulatory compliance and through-hole mounting.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters for substituting TIP41C-S?
A1: Key parameters are NPN transistor type, maximum collector current (≥6 A), collector-emitter breakdown voltage (100 V), Vce saturation, DC current gain, mounting type (through hole), and package (TO-220-3). Environmental compliance such as ROHS3 must also be matched.

Q2: Are TO-220-3 and TO-220AB packages compatible for substitution?
A2: TO-220-3 and TO-220AB are functionally similar in mounting and pin configuration. Verify package suffix for mechanical fit.

Q3: Is DC current gain (hFE) critical for substituting TIP41C-S?
A3: Substitute parts must meet or exceed the minimum DC current gain specified (15 @ 3A, 4V). Some alternatives provide substantially higher gain.

Q4: Can parts with higher collector current (Ic) or power rating be substituted?
A4: Devices with higher Ic or power rating are accepted if other electrical and mechanical parameters match.

Q5: What environmental certifications are required for substitutes?
A5: Substitutes must maintain the same ROHS3 compliance status as TIP41C-S.

Q6: Why is substitution necessary for TIP41C-S?
A6: TIP41C-S is obsolete; substitutes are necessary to maintain product availability and support ongoing designs.

Q7: Are operating temperature ranges considered in substitution?
A7: All listed substitutes comply with the specified operating junction temperature requirements (up to 150°C TJ).
