Key Parameters

Substitute Part Grouping Explanation

Substitution of the VDRUS14X320BKE is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical values for maximum AC and DC voltage ratings, varistor voltage specifications (minimum, typical, and maximum), surge current capacity, energy dissipation, circuit count, capacitance, operating temperature range, mounting type, and package form factor. All substitute parts must belong to the same VDRUS series and retain the same through-hole disc 14mm package configuration. Compliance certifications including RoHS3 status, REACH classification, and moisture sensitivity level must remain unchanged. The substitution logic ensures that the replacement component functions identically within the original circuit design without requiring layout modifications or performance re-evaluation.

Parameter Comparison

Engineering Selection Recommendations

The VDRUS14X320BSE is a direct parametric equivalent to the VDRUS14X320BKE. Both components are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain identical electrical specifications across all voltage, current, and energy parameters. Both parts are Active products with RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. The through-hole disc 14mm package configuration is identical, permitting direct board-level substitution without PCB layout modifications. Selection between these two parts may be based on inventory availability, lead time, or procurement source, as no electrical or mechanical differentiation exists between them. Both components operate within the −40 to +125 °C temperature range and maintain the same capacitance and surge current specifications required for transient voltage suppression in industrial and commercial applications.
