MBS4850 DC EMC/EMI Line Filter - Equivalent & Substitute Parts

Part Overview

The MBS4850 is a DC EMC/EMI line filter rated for 48VDC at 50A with chassis mount configuration and M6 threaded post termination. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system integration. The MBS4850 series represents a single-stage filtering solution designed for general-purpose DC applications requiring electromagnetic compatibility management.

Key Parameters

Substitute Part Grouping Explanation

The RDEN-048050 qualifies as a manufacturer-recommended substitute for the MBS4850 based on the following critical parameters:

• Voltage Rating: Both parts maintain 48VDC rated voltage
• Current Capacity: Both parts support 50A operation
• Filter Type & Configuration: Both are DC single-stage EMC/EMI filters
• Mounting & Termination: Both use chassis mount with threaded post termination
• Application Category: Both serve general-purpose DC filtering applications
• Manufacturer: Both are manufactured by TDK-Lambda Americas Inc

The RDEN-048050 represents an active product status replacement, ensuring continued availability and support for the obsolete MBS4850.

Parameter Comparison

Engineering Selection Recommendations

The RDEN-048050 is the manufacturer-recommended substitute for the obsolete MBS4850. Both parts maintain identical electrical specifications (48VDC, 50A, DC single-stage configuration) and mechanical mounting requirements (chassis mount). The RDEN-048050 offers the advantage of active product status, ensuring ongoing availability and manufacturer support.

The RDEN-048050 provides an extended operating temperature range (-30°C to 85°C versus -25°C to 85°C) and RoHS compliance certification. The termination style differs between the two parts: MBS4850 uses M6 threaded posts while RDEN-048050 uses M5 threaded posts. This difference requires mechanical design verification to ensure compatibility with existing mounting hardware and circuit board layouts.

Frequently Asked Questions (FAQ)

Q: What are the critical electrical parameters for substitution between MBS4850 and RDEN-048050?

A: The critical electrical parameters are voltage rating (48VDC), current capacity (50A), filter type (DC), and configuration (single stage). Both parts meet these specifications identically.

Q: How does the threaded post size difference affect substitution?

A: The MBS4850 uses M6 threaded posts while RDEN-048050 uses M5 threaded posts. This mechanical difference requires verification of mounting hole compatibility in the target application. Adapter hardware or design modification may be necessary.

Q: Is the RDEN-048050 suitable for all MBS4850 applications?

A: The RDEN-048050 is electrically and functionally equivalent for general-purpose DC filtering applications. Mechanical compatibility must be confirmed due to the M6 to M5 threaded post transition.

Q: What is the significance of the extended temperature range in RDEN-048050?

A: The RDEN-048050 operates from -30°C to 85°C compared to the MBS4850 range of -25°C to 85°C. This provides an additional 5°C of low-temperature capability, beneficial for applications requiring extended environmental performance.

Q: Does RoHS compliance affect the substitution decision?

A: The RDEN-048050 is RoHS compliant, while the MBS4850 status is not specified. For applications subject to RoHS requirements, the RDEN-048050 provides documented compliance assurance.
