Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SA1215 are selected strictly based on matching the following key parameters: transistor type (PNP), maximum collector-emitter voltage (160 V), maximum collector current (15 A), Vce saturation at the specified current and base current, maximum collector cutoff current, minimum DC current gain at specified collector current and voltage, maximum power dissipation, transition frequency, operating temperature, mounting type (through hole), RoHS compliance, and moisture sensitivity level. Physical package differences are also considered for mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection of 2SA1386 as an equivalent or substitute for the 2SA1215 is supported by strict alignment of critical electrical characteristics, RoHS compliance, and MSL. The 2SA1386 is currently active, whereas the 2SA1215 is obsolete. Both are RoHS compliant and rated as MSL 1 (Unlimited), ensuring compatibility with standard lead-free manufacturing and storage processes. Mechanical differences between the MT-200 and TO-3P packages must be considered in board designs or mounting procedures.

Frequently Asked Questions (FAQ)

Q1: What parameters are most critical when selecting a substitute for the 2SA1215?
A1: Key parameters for substitution include transistor type, maximum collector-emitter voltage, maximum collector current, Vce saturation at specified test conditions, collector cutoff current, minimum DC current gain, maximum power handling, transition frequency, and operating temperature.

Q2: Is the 2SA1386 considered a direct replacement for the 2SA1215?
A2: The 2SA1386 matches the primary functional and electrical parameters of the 2SA1215, including voltage, current, and gain. Differences exist in package type and power handling, which must be considered for mechanical and thermal design compatibility.

Q3: Are the mounting types compatible between the 2SA1215 and its substitutes?
A3: Both 2SA1215 and 2SA1386 are through-hole mounting types; however, there is a difference in package format (MT-200 vs. TO-3P).

Q4: Are there differences in RoHS compliance or MSL ratings between 2SA1215 and 2SA1386?
A4: Both parts are RoHS compliant and have a moisture sensitivity level rating of 1 (Unlimited), permitting similar handling and compliance characteristics.

Q5: Does substituting 2SA1386 impact the system's maximum power or frequency rating?
A5: The 2SA1386 is rated for lower maximum power dissipation (130 W vs. 150 W) and transition frequency (40MHz vs. 50MHz). These differences must be evaluated with respect to the application’s electrical and thermal requirements.

Q6: Is 2SA1215 available for new designs?
A6: The 2SA1215 is marked as Obsolete, making it unsuitable for new designs where long-term availability is required. The 2SA1386 is Active and available from inventory.
