Key Parameters

Substitute Part Grouping Explanation

Substitution of the MT5010A-BP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Type: Three Phase (required for three-phase rectification function)
• Technology: Standard (process compatibility)
• Current - Average Rectified (Io): 50 A (current handling capacity)
• Package / Case: MT-35A form factor (mechanical fit and terminal compatibility)
• Mounting Type: Chassis Mount or QC Terminal (both acceptable for MT-35A package)

Allowable Parameter Variations:

• Voltage - Peak Reverse (Max): Substitute may exceed 1 kV (higher voltage rating provides backward compatibility)
• Voltage - Forward (Vf): Minor variations acceptable if within thermal and efficiency constraints
• Operating Temperature Range: Substitute may have narrower range if minimum remains at or below -40°C and maximum at or above 150°C
• Product Status: Active status preferred for obsolete components

The MT5016A-BP meets all mandatory criteria while providing enhanced voltage rating (1.6 kV), maintaining identical current capacity (50 A), and utilizing the same MT-35A package footprint.

Engineering Selection Recommendations

Primary Substitute: MT5016A-BP

The MT5016A-BP is the manufacturer-recommended substitute for the obsolete MT5010A-BP. Selection of this substitute is based on the following engineering factors:

Product Status Consideration: The MT5016A-BP maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete MT5010A-BP.

Electrical Compatibility: The substitute maintains identical three-phase rectification capability and 50 A average rectified current rating. The elevated peak reverse voltage rating (1.6 kV versus 1 kV) provides enhanced overvoltage margin without compromising circuit function in applications designed for 1 kV operation.

Compliance and Certification: The MT5016A-BP is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Mechanical Compatibility: Both components utilize the MT-35A package footprint. The transition from 5-Square to 4-Square terminal configuration within the same MT-35A package maintains mechanical fit while the QC Terminal mounting type provides equivalent chassis mount functionality.

Temperature Operating Range: The substitute operating range (-40°C ~ 150°C) covers the majority of industrial applications. Applications requiring operation below -40°C require verification against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can MT5016A-BP directly replace MT5010A-BP in existing designs?

A: Yes. Both components share the MT-35A package footprint, identical current rating (50 A), and three-phase rectification function. The higher voltage rating (1.6 kV) of the substitute provides backward compatibility with 1 kV applications. Terminal configuration changes from 5-Square to 4-Square require verification of connection compatibility with existing wiring harnesses.

Q: What is the significance of the voltage rating difference (1 kV vs. 1.6 kV)?

A: The MT5016A-BP's 1.6 kV peak reverse voltage rating exceeds the MT5010A-BP's 1 kV rating. In applications operating at or below 1 kV, the substitute provides additional overvoltage margin. Applications designed for the 1 kV rating will function identically with the higher-rated substitute component.

Q: Are there temperature range limitations when substituting?

A: The MT5016A-BP operating range (-40°C ~ 150°C) is narrower than the MT5010A-BP (-55°C ~ 150°C) at the minimum temperature. Applications requiring operation below -40°C must retain the original MT5010A-BP or identify alternative components with extended low-temperature ratings.

Q: What is the difference between Chassis Mount and QC Terminal mounting types?

A: Both mounting types are compatible with the MT-35A package. Chassis Mount and QC Terminal refer to terminal connection styles. Verification of terminal compatibility with existing circuit board or chassis connections is required before substitution.

Q: Does the forward voltage difference affect circuit performance?

A: The forward voltage (Vf) is specified at different test currents: MT5010A-BP at 25 A and MT5016A-BP at 12 A. Both specify 1.2 V maximum. The different test conditions reflect component characterization methods. Circuit performance impact depends on specific application current levels and thermal design.

Q: Is the MT5016A-BP the only available substitute?

A: Based on provided data, MT5016A-BP is the manufacturer-recommended substitute. Other three-phase bridge rectifiers with 50 A current rating and MT-35A package compatibility may exist but are not included in this reference.

Q: What compliance certifications should be verified for new applications?

A: The MT5016A-BP is ROHS3 compliant and REACH unaffected. Both components share EAR99 ECCN classification. Specific application requirements may necessitate additional certifications or compliance verification beyond these standard designations.
