Parameter Comparison

Engineering Selection Recommendations

The main part, Vicor Corporation VI-J4F-EX, is obsolete. The substitute part VI-J4F-EX-F1 is active, allowing continued sourcing within the same product series. Both parts are RoHS non-compliant and REACH unaffected, maintaining consistent compliance requirements. There are no differences in certifications, electrical ratings, or main features based on the input parameters.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting the VI-J4F-EX DC DC converter?
A1: The critical parameters are: input voltage range (55V–100V), output voltage (72V), output current (1.04A), output power (75W), isolation voltage (3 kV), module type (isolated), application suitability (ITE Commercial), operating temperature (-10°C to 100°C), package type (half brick), and compliance statuses.

Q2: Is the substitute part VI-J4F-EX-F1 pin-to-pin and functionally compatible?
A2: Both are half brick, through-hole, isolated modules with matching electrical specifications and base product numbers, indicating compatibility in form, fit, function, and mounting method according to provided parameters.

Q3: Do RoHS and REACH statuses differ between VI-J4F-EX and VI-J4F-EX-F1?
A3: No. Both parts are RoHS non-compliant and REACH unaffected.

Q4: Does the substitute part have any differences in physical size?
A4: The size dimensions differ: VI-J4F-EX is 2.28" L x 2.40" W x 0.50" H (57.9mm x 70.0mm x 12.7mm); VI-J4F-EX-F1 is 2.28" L x 1.86" W x 0.79" H (57.9mm x 47.2mm x 20.1mm). Both maintain the half brick classification.

Q5: Is there any difference in MSL (Moisture Sensitivity Level)?
A5: No. Both are classified as Not Applicable for Moisture Sensitivity Level.

Q6: Are there differences in safety features or efficiencies between the two parts?
A6: No. Both provide OCP (Over Current Protection), SCP (Short Circuit Protection), and 88% efficiency.
