Substitute Part Grouping Explanation

Substitution of the MD16110A-BM2MM is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Diode configuration must be 1 Pair Series Connection
• Voltage - DC Reverse (Vr) (Max) must equal 1600 V
• Current - Average Rectified (Io) (per Diode) must equal 110 A
• Recovery speed classification must be Standard Recovery >500ns, > 200mA (Io)
• Operating temperature range must span -40°C ~ 150°C

Mechanical Equivalence Criteria:

• Mounting type must be Chassis Mount
• Package classification must support chassis mount configuration

Compliance Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

The MDMA110P1600TG manufactured by IXYS meets all specified electrical and mechanical parameters, with the primary difference being the package designation (TO-240AA versus A-3 module) and improved forward voltage characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MDMA110P1600TG is the designated substitute for the obsolete MD16110A-BM2MM. Both components maintain identical electrical ratings for voltage, current, and recovery speed specifications. The substitute part is currently in active production status, ensuring supply chain continuity.

Both components carry ROHS3 compliance certification and MSL rating of 1 (Unlimited), meeting environmental and moisture sensitivity requirements. The MDMA110P1600TG demonstrates improved reverse leakage characteristics (200 µA versus 500 µA at 1600 V), indicating enhanced device performance.

The primary design consideration is the package transition from A-3 module to TO-240AA. This change requires mechanical redesign of the mounting interface and thermal management structure. Thermal performance, mechanical fit, and electrical connection routing must be evaluated within the specific application context.

Frequently Asked Questions (FAQ)

Q: Can the MDMA110P1600TG directly replace the MD16110A-BM2MM without circuit modification?

A: Electrical substitution is valid based on identical voltage, current, and recovery speed ratings. However, the package change from A-3 module to TO-240AA requires mechanical redesign of the mounting structure and thermal interface. Circuit topology remains unchanged.

Q: What is the significance of the forward voltage difference between the two parts?

A: The MD16110A-BM2MM specifies 1.6 V @ 350 A, while the MDMA110P1600TG specifies 1.18 V @ 110 A. These measurements are taken at different current levels and therefore are not directly comparable. Both parts meet their respective forward voltage specifications within their rated operating conditions.

Q: Does the improved reverse leakage of the MDMA110P1600TG affect circuit design?

A: The MDMA110P1600TG exhibits lower reverse leakage (200 µA versus 500 µA at 1600 V). This represents improved device characteristics and does not require circuit modification. Applications sensitive to leakage current may benefit from this improvement.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both components specify identical operating junction temperature ranges of -40°C to 150°C, ensuring thermal compatibility across the full operating envelope.

Q: What compliance certifications apply to both parts?

A: Both the MD16110A-BM2MM and MDMA110P1600TG carry ROHS3 compliance certification and MSL rating of 1 (Unlimited), meeting current environmental and moisture sensitivity standards.

Q: Is the TO-240AA package compatible with existing A-3 module mounting hardware?

A: No. The TO-240AA package requires different mounting hardware and thermal interface design compared to the A-3 module. Mechanical redesign of the mounting structure is necessary for implementation.
