Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the 2SC5071 is based strictly on matching the essential electrical and mechanical parameters defined in the product category for NPN Bipolar (BJT) transistors. These include: transistor type, collector current rating, collector-emitter voltage breakdown, DC current gain at specified operating points, power dissipation, mounting type, package compatibility, operating temperature, and compliance requirements. Only parts meeting or exceeding these criteria and compatible with through hole mounting and relevant package types are considered.

Parameter Comparison

Engineering Selection Recommendations

2SC5071 is obsolete; substitute selection must favor parts with matching or higher electrical ratings and equivalent compliance status. BUV48A by STMicroelectronics meets RoHS3 compliance and MSL 1 (Unlimited), aligning with the 2SC5071’s certifications. Package style is different (TO-247-3 vs. TO-3P-3) and must be verified for mechanical fitting in the target application. Non-new design status is noted for BUV48A. Substitute part approval should follow component status and regulatory compliance requirements as provided.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters used for substituting NPN BJT transistors in this category?
Substitution is strictly based on transistor type, collector current, collector-emitter breakdown voltage, power rating, DC current gain, operating temperature, mounting type, package, and compliance certifications.

Q2: Does BUV48A directly replace 2SC5071 in all applications?
BUV48A matches or exceeds the key electrical parameters. Mechanical compatibility must be based on actual package and footprint (TO-247-3 vs. TO-3P-3).

Q3: How do RoHS and MSL ratings affect part selection?
Both 2SC5071 and BUV48A are RoHS compliant and rated MSL 1 (Unlimited); adherence to these ratings is required for regulatory and handling processes in manufacturing.

Q4: Does the package difference impact substitution?
Yes, TO-3P-3 and TO-247-3 differ in size and terminal layout. Review mechanical drawings and PCB layout to ensure compatibility.

Q5: Is current gain (hFE) a strict matching requirement?
DC current gain is a substitution parameter; select parts with hFE ratings equal to or above the original part, as shown in the comparison table.

Q6: Does frequency transition (ft) matter in this substitution?
Frequency data is available for 2SC5071 but not for BUV48A in the provided specifications. Substitution is based only on provided parameters.

Q7: Are both main and substitute parts suitable for high temperature operation?
Both parts are rated for 150°C (TJ) operation, meeting high temperature endurance requirements outlined in the specifications.
