Equivalent & Substitute Parts for NCM6S4803C

Part Overview

The NCM6S4803C from Murata Power Solutions Inc. is an isolated DC-DC converter module designed for ITE (Commercial) and Medical applications, providing a single 3.3V output at up to 1.52A from a wide 18V–75V DC input range. With features such as remote On/Off, over-temperature protection (OTP), short-circuit protection (SCP), and under-voltage lockout (UVLO), this 6 W power module offers robust performance and 5.2 kV isolation. The product status is listed as obsolete, necessitating the identification of alternative or substitute models that conform to the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The selection of substitute DC-DC converter modules for NCM6S4803C is strictly based on the following key parameters, ensuring functional compatibility within this product category:

• Type (Isolated Module)
• Number of Outputs (1)
• Input Voltage Range (18V–75V)
• Output Voltage (3.3V)
• Maximum Output Current (1.52A)
• Mounting Type (Through Hole)
• Operating Temperature (-40°C ~ 85°C)
• RoHS Compliance
• Output Features (OTP, SCP, UVLO)

Only substitute parts meeting these parameters are grouped for comparison. Power rating, isolation voltage, package, and exact series/applications are also considered where available in the provided data.

Parameter Comparison

Engineering Selection Recommendations

NCM6S4803C is obsolete, while NCS6S4803C is active and ROHS3 compliant. Both parts are manufactured by Murata Power Solutions Inc. and provide equivalent electrical input and output specifications, operating temperature range, and through hole mounting, meeting the allowed substitute selection criteria. RoHS compliance and product status are aligned with requirements for interchangeable use within these parameters.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for selecting a substitute DC-DC converter for NCM6S4803C?
A1: Essential parameters include input voltage range (18V–75V), output voltage (3.3V), maximum output current (1.52A), number of outputs (1), module type (Isolated), mounting type (Through Hole), and operational temperature range (-40°C ~ 85°C). RoHS compliance and required features must also be evaluated.

Q2: How does package or case difference influence substitutability?
A2: Substitution requires the same basic mounting type (Through Hole). The exact package/case and pin count may impact mechanical or PCB compatibility and must be checked for direct fit.

Q3: Are all features present in the substitute part?
A3: Both parts share OTP, SCP, and UVLO features. Remote On/Off is only indicated on NCM6S4803C.

Q4: Can the substitute NCS6S4803C be used in medical applications?
A4: The application field for NCS6S4803C is ITE (Commercial) as provided. For NCM6S4803C, both ITE (Commercial) and Medical are listed.

Q5: How does isolation voltage differ between the main and substitute parts?
A5: NCM6S4803C has 5.2 kV isolation, while NCS6S4803C lists 1.5 kV. This must be considered in designs requiring higher isolation.

Q6: Why is substitution necessary for NCM6S4803C?
A6: The primary reason is the obsolete product status of NCM6S4803C. Substitution ensures continued availability and compliance with standards.
