Key Parameters

Substitute Part Grouping Explanation

Substitute parts for BD897A-S are strictly determined based on matched or better performance in the following key parameters: transistor type (NPN Darlington), maximum collector current (Ic), maximum collector-emitter breakdown voltage (Vce), saturation voltage (Vce), cutoff current, minimum DC current gain (hFE), power rating, operating temperature range, mounting type, package outline, and compliance certifications. These parameters enable accurate and direct substitution in existing designs without requiring changes to electrical or mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

BD897A-S is listed as obsolete, while 2N6043G is active and ROHS3 compliant. Both parts share the same transistor type, mounting method, package, and key compliance certifications (EAR99, HTSUS, RoHS). Selection of substitute should be based on the product's availability and identical compliance status in regulated supply chains.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match for direct substitution between BD897A-S and 2N6043G?
