Substitute Part Grouping Explanation

Substitute grouping is based on explicit matching of category, polarity, maximum collector current, voltage rating, power dissipation, mechanical package, mounting type, transition frequency, operating temperature, compliance, and product status. Only substitute transistor models within the same Bipolar (BJT) product category that share parameters including transistor type (PNP), collector current (15 A), collector-emitter breakdown voltage (180 V), power dissipation (130 W), transition frequency, mounting style (through-hole), mechanical case (TO-3P-3, SC-65-3), compliance status, and supplier device package are included.

Parameter Comparison

Engineering Selection Recommendations

Both 2SA1492 and its substitute 2SA1386A are marked as active status, are ROHS3 compliant, have matched mechanical mounting and packaging (TO-3P-3, SC-65-3, through-hole), and share identical characteristics for collector current, voltage breakdown, power rating, and environmental ratings. The substitute is suitable for direct interchange in contexts requiring comparable compliance and procurement transparency.

Frequently Asked Questions (FAQ)

Q1: What are the minimum criteria for accepting a substitute for 2SA1492?
