Key Parameters

Substitute Part Grouping Explanation

Substitute parts have been selected strictly based on the matching and/or compatible parameters, including transistor type (NPN), collector current rating (5 A), collector-emitter breakdown voltage (≥500 V), Vce saturation, collector cutoff current, DC current gain, maximum power dissipation, transition frequency, operating temperature, mounting type (Through Hole), package type (TO-220F and variants), RoHS status, and moisture sensitivity level. All criteria originate directly from the provided main part specification and are matched as listed.

Parameter Comparison

Engineering Selection Recommendations

Substitutes BUJ303AX,127 and FJPF5021OTU are currently listed as active products, suitable for consideration in applications previously utilizing the obsolete Sanken 2SC4518. All listed substitute parts meet RoHS compliance requirements. Moisture Sensitivity Level for BUJ303AX,127 is MSL 1 (Unlimited), matching the main part, while FJPF5021OTU is noted as Not Applicable. ECCN and other compliance values are directly matched from the provided data.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters for substituting the 2SC4518 transistor?
A1: The most critical substitution parameters are transistor type (NPN), maximum collector current (5 A), collector-emitter breakdown voltage (≥500 V), package/case format (TO-220F variants), power dissipation (≥32 W), and compliance indicators (RoHS, MSL).

Q2: Are all substitute parts physically compatible with the original TO-220F mounting footprint?
A2: All substitute parts are specified with the TO-220F or TO-220F-3 package and correspond to through-hole mounting, matching the mechanical format of the original component.

Q3: Is there any difference in compliance status between the main part and substitutes?
A3: All substitutes and the main part are designated as RoHS compliant. The MSL for BUJ303AX,127 matches the main part ("1" Unlimited); FJPF5021OTU lists MSL as Not Applicable, based on the provided data.

Q4: Do the substitutes differ in electrical performance parameters?
A4: The main distinctions among substitutes are power rating and DC current gain, as specified in the comparison table. All substitutes meet or exceed the minimum required electrical parameters, as listed.

Q5: Why is substitution necessary for the 2SC4518?
A5: The 2SC4518 is marked as obsolete; therefore, active and compliant substitute models are required for continued production support and maintenance.
