Key Parameters

Substitute Part Grouping Explanation

Substitution of DC-DC converters within this category is determined by strict alignment of essential parameters. The key parameters for suitability are: number of outputs, input voltage range, output voltage, output current, output power, voltage isolation, operating temperature range, mounting type, package dimensions, RoHS compliance, moisture sensitivity level, ECCN, and application compatibility. Only part numbers matching these permitted ranges and physical constraints are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The XP Power RCQ50110S24 DC-DC converter is flagged as obsolete. The RDF5072WS24 is a substitute that is active and ROHS3 compliant, and shares the same mounting type, output power, number of outputs, output voltage, and device dimensions. Both parts comply with RoHS requirements and share the same moisture sensitivity level (MSL 1) and ECCN codes. Selection should be based on product status and matched compliance certifications as detailed above.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting a substitute for RCQ50110S24?
A1: Critical parameters include number of outputs, input voltage range, output voltage, output current, power rating, isolation voltage, operating temperature range, mounting type, package size, and all compliance certifications such as RoHS and MSL.

Q2: Are the packages of RCQ50110S24 and RDF5072WS24 compatible?
A2: Both parts have identical dimensions (2.28" x 1.45" x 0.50") and utilize through-hole mounting. RCQ50110S24 uses an 8-DIP Module, while RDF5072WS24 uses a Quarter Brick format. Mechanical compatibility must be verified specifically for package type interface, as only dimensions are strictly matched.

Q3: Does the substitute part meet similar application categories?
A3: Yes, both RCQ50110S24 and RDF5072WS24 are designed for ITE (Commercial) and Railway applications.

Q4: How does RoHS compliance and MSL affect compatibility?
A4: Both the main part and substitute are ROHS3 compliant and have the same moisture sensitivity level rating (MSL 1), ensuring direct compatibility with standard assembly and handling requirements.

Q5: Is there a difference in input voltage range or isolation voltage?
A5: RDF5072WS24 has a wider input voltage range (14V–160V vs. 66V–160V). Voltage isolation differs: RCQ50110S24 is rated at 3 kV; RDF5072WS24 is rated at 1.5 kV. Selection should consider allowed isolation rating for the intended application.
