Key Parameters

Substitute Part Grouping Explanation

Substitute components for the Vicor VI-J3H-CX are identified strictly by matching essential electrical and mechanical parameters: input voltage range, output voltage and current, output power, isolation voltage, operating temperature, efficiency, mounting type, package/case size, number of outputs, and feature set. Only parts meeting all indicated specifications and dimensions listed can be considered as direct substitutes within the isolated DC-DC converter module product category. Compliance and status qualifiers are included for precise selection.

Parameter Comparison

Engineering Selection Recommendations

VI-J3H-CX is classified as Obsolete, while VI-J3H-CX-F1 is listed as Active. Both share identical electrical and feature parameters, and both are RoHS non-compliant and REACH unaffected. The VI-J3H-CX-F1 can be directly substituted for VI-J3H-CX if mechanical differences in package dimensions are acceptable for the intended application environment.

Frequently Asked Questions (FAQ)

Q1: What are the key substitution parameters for VI-J3H-CX?
A1: Electrical parameters (input voltage, output voltage, output current, isolation, power), features, temperature range, mounting, and package/case dimensions must all match or be compatible within the system requirements.

Q2: Are package/case size or mounting variations permissible in substitution?
A2: Substitution is permitted where through-hole mounting is compatible. Package/case size differences should be evaluated for fit and thermal management within the target assembly.

Q3: Does RoHS or REACH status affect substitution?
A3: Both VI-J3H-CX and VI-J3H-CX-F1 are RoHS non-compliant and REACH unaffected. No change occurs regarding environmental or regulatory qualifications in substitution.

Q4: Is feature parity maintained between main and substitute parts?
A4: Both parts offer OCP (Over-Current Protection) and SCP (Short-Circuit Protection).

Q5: How does product status influence selection?
A5: With VI-J3H-CX marked "Obsolete" and VI-J3H-CX-F1 "Active," selection favors the active substitute for ongoing production and support scenarios.

Q6: Are there electrical performance differences between VI-J3H-CX and VI-J3H-CX-F1?
A6: All rated electrical parameters are identical according to the provided data. Only mechanical package differences are indicated.
