EUPEC BSM200GB170DLC Replacement for DLC Series

Product Overview

EUPEC BSM200GB170DLC Replacement for DLC Series: Seamless Transition to Modern IGBT Power Control

The EUPEC BSM200GB170DLC is a 200A / 1700V half-bridge IGBT power module from the renowned Infineon/EUPEC DLC Series, engineered for demanding industrial drive, traction, and power conversion applications. As legacy inverter platforms age and original DLC Series modules approach end-of-life, plant engineers and procurement teams increasingly require a verified, drop-in replacement that preserves existing wiring harnesses, gate driver boards, heatsink mounting patterns, and control logic — without forcing a full drive redesign or extended production shutdown.

TOPNLMS specializes in sourcing, testing, and supplying the BSM200GB170DLC as a direct replacement for obsolete or failed modules in active industrial systems. Whether you are maintaining a medium-voltage AC drive, a regenerative braking unit, a UPS inverter stage, or a high-power induction heating system, this module delivers the electrical and mechanical compatibility your retrofit demands.

Seamless Upgrade Solutions

A successful BSM200GB170DLC retrofit rarely involves the IGBT module alone. In practice, the migration from an aging drive platform to a modernized power stage requires careful coordination of surrounding components. When replacing a failed or obsolete half-bridge module in a medium-voltage inverter, engineers typically revisit the gate driver board — often a dedicated IGBT driver such as the Concept 2SD315AI or equivalent — to confirm that gate resistance values and desaturation thresholds remain appropriate for the new module’s switching characteristics.

The DC bus capacitor bank and DC link film capacitors adjacent to the module should be inspected for ESR degradation, particularly in systems that have operated for more than five years. In multi-phase inverter cabinets, the BSM200GB170DLC is frequently installed alongside companion modules such as the BSM150GB170DLC or BSM300GB120DN2 in parallel or series configurations; replacing only the failed unit while leaving aged siblings in service increases the risk of cascade failure.

For systems using a Siemens SIMOVERT MASTERDRIVES or ABB ACS800 inverter platform, the power module replacement is often accompanied by recalibration of the current measurement board and replacement of the LEM current transducer (e.g., LEM LA 200-P or equivalent) mounted on the DC bus bar. The bus bar itself — typically a laminated copper assembly — should be torqued to specification after module installation to ensure low-inductance connections that protect the new IGBT from voltage spikes during switching transients.

In traction and crane drive applications, the BSM200GB170DLC upgrade is commonly paired with a replacement of the brake chopper IGBT module (such as the BSM200GB120DN2 or SKM200GB12T4) and the associated braking resistor assembly. Control-side components — including the PLC I/O interface card, speed encoder feedback module, and fieldbus communication adapter (PROFIBUS DP or CANopen) — generally do not require modification, as the power stage replacement is transparent to the control layer.

Where the original drive cabinet uses a 24 VDC auxiliary power supply module to power gate drivers and control boards, this supply should be load-tested prior to recommissioning. Aging SMPS units in legacy cabinets are a common secondary failure point discovered during IGBT replacement projects. Similarly, the NTC thermistor embedded in or adjacent to the module should be verified for correct resistance-temperature response, as the thermal protection circuit depends on accurate readings to prevent over-temperature shutdown during the first load cycles after replacement.

Retrofit Guidance FAQ

Q: Is the BSM200GB170DLC a direct pin-compatible replacement for my existing DLC Series module?
A: Yes. The BSM200GB170DLC uses the standard EUPEC 62 mm DLC package with identical power terminal positions, auxiliary pin layout, and base plate mounting holes. No mechanical adapter or wiring modification is required for same-series replacements.

Q: Do I need to modify my gate driver circuit?
A: In most cases, no. The module is designed for standard ±15 V IGBT gate drive. However, we recommend verifying the gate resistor (R_g) value against the module’s datasheet switching energy curves. If the original module used a different R_g, minor adjustment may reduce switching losses or EMI.

Q: Can this module replace a 1200 V rated unit in my system?
A: The BSM200GB170DLC is rated at 1700 V V_CES. It can replace a 1200 V module of the same current rating and footprint, providing additional voltage margin. Confirm that the gate driver’s desaturation detection threshold is compatible with the 1700 V device characteristics.

Q: What communication protocols does this module support?
A: As a power semiconductor, the BSM200GB170DLC does not implement a communication protocol. It is controlled by PWM signals from the gate driver, which in turn receives commands from the drive controller via PROFIBUS, CANopen, EtherCAT, or analog reference — depending on your drive platform. The module replacement has no impact on the fieldbus layer.

Q: How much physical space does the module require in the cabinet?
A: The DLC package dimensions are standardized. The module mounts directly to the heatsink using M6 bolts at the standard DLC pitch. No additional clearance or cabinet modification is required compared to the original module.

Q: What testing is performed before shipment?
A: Each BSM200GB170DLC unit undergoes visual inspection, static parameter verification (V_CE(sat), leakage current, gate threshold), and isolation voltage testing prior to packaging. A test report is available upon request.

Warranty Assurance

Every BSM200GB170DLC supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. This warranty covers verified manufacturing defects and parameter non-conformance identified under normal operating conditions consistent with the module’s datasheet ratings.

Pre-shipment testing: All units are inspected and electrically verified before dispatch. Packaging uses anti-static foam inserts and moisture barrier bags to prevent transit damage.
