MP6KE56AE3 Equivalent & Substitute Parts

Part Overview

The MP6KE56AE3 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose voltage clamping applications. This through-hole component operates with a reverse standoff voltage of 47.8V and provides peak pulse current handling of 7.8A with a maximum clamping voltage of 77V. The device is qualified to MIL-PRF-19500 military standards and maintains an active product status. Substitute parts are identified to provide alternative sourcing options when the primary component is unavailable or when inventory requirements necessitate qualified alternatives.

Substitute parts must maintain electrical performance within the specified voltage and current ranges and utilize compatible through-hole T-18 axial packaging to ensure direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (MP6KE56AE3): The MP6KE56AE3 maintains active product status and carries military-grade qualification under MIL-PRF-19500. This component is suitable for applications requiring military-specification compliance and is available in current inventory (1027 pcs). The device is RoHS non-compliant, which may be a consideration for applications subject to RoHS directives.

Substitute Component (P6KE56A): The P6KE56A from Fairchild Semiconductor is an active product that provides equivalent electrical and mechanical characteristics within the transient voltage suppressor category. Both components share identical package specifications (T-18, Axial through-hole), unidirectional channel configuration, and export classification (EAR99). The P6KE56A is available in higher inventory quantity (2300 pcs), providing enhanced supply chain flexibility.

Selection Basis: Component selection should be determined by application requirements regarding military qualification, supply availability, and regulatory compliance status. Both parts are active products with compatible electrical performance parameters and identical mechanical packaging, enabling direct functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the P6KE56A directly replace the MP6KE56AE3 in existing circuit designs?

A: Yes. Both components are unidirectional TVS diodes with identical T-18 axial through-hole packaging, matching electrical performance parameters (47.8V reverse standoff, 77V clamping voltage, 7.8A peak pulse current), and equivalent functional specifications. Direct substitution is supported at the circuit board level without design modification.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by voltage ratings (reverse standoff, breakdown, and clamping voltages), peak pulse current capacity, power dissipation rating, and channel configuration (unidirectional). The MP6KE56AE3 and P6KE56A maintain matching specifications across all these parameters.

Q: Are there packaging differences between the MP6KE56AE3 and P6KE56A?

A: No. Both components utilize identical T-18 axial through-hole packaging, enabling direct mechanical and electrical compatibility in printed circuit board layouts without modification to footprints or mounting requirements.

Q: What is the significance of the military qualification (MIL-PRF-19500) on the MP6KE56AE3?

A: Military qualification indicates the component meets specific performance, reliability, and testing standards established by military procurement specifications. Applications requiring military-grade component certification should specify the MP6KE56AE3. The P6KE56A does not carry this qualification.

Q: How do the inventory levels affect component selection?

A: The MP6KE56AE3 has 1027 pcs in stock, while the P6KE56A has 2300 pcs available. Higher inventory availability of the P6KE56A may provide supply chain advantages for applications with extended production runs or when rapid replenishment is required.

Q: Are there compliance differences between these components?

A: Both components share identical export classification (EAR99) and tariff codes (HTSUS 8541.10.0080). The MP6KE56AE3 is RoHS non-compliant, while RoHS status for the P6KE56A is not specified in the provided data. Applications subject to RoHS directives should verify compliance requirements with the component manufacturer.
