Key Parameters

Substitute Part Grouping Explanation

Substitute part selection within the isolated module DC-DC converter category is strictly determined by matching electrical and mechanical parameters specified for the main part. These key substitution parameters include input voltage range (42V to 60V), output voltage (95V), output current (790mA), output power (75 W), isolation voltage (3 kV), application suitability (ITE Commercial), protection features (OCP, SCP), efficiency (90%), mounting type (Through Hole), package/case (Half Brick), and operating temperature (-25°C to 100°C). Other compliance and regulatory fields such as RoHS, REACH, ECCN, and HTSUS are also matched to ensure compatibility in certified environments.

Parameter Comparison

Engineering Selection Recommendations

The VI-J3B-CX is obsolete, and the VI-J3B-CX-F1 is classified as active. Both models share matching electrical, mechanical, and compliance parameters including RoHS status, REACH status, ECCN, and HTSUS codes. Selection may consider product status and availability. Both parts are RoHS non-compliant and are unaffected by REACH, making them suitable for environments with similar regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: What enables substitution between VI-J3B-CX and VI-J3B-CX-F1?
Substitution is enabled by identical input voltage range, output voltage and current ratings, power, isolation voltage, protection features, efficiency, mounting style, and compliance specifications.

Q2: Are there physical dimension differences to be considered?
Both models use the Half Brick package with matching length. Width and height differ: VI-J3B-CX is 2.40" W x 0.50" H; VI-J3B-CX-F1 is 1.86" W x 0.79" H. Review mechanical layouts to verify form factor compatibility.

Q3: Are both modules suitable for the same application category?
Both are specified for ITE (Commercial) applications, and feature the same electrical and protection characteristics.

Q4: Is regulatory compliance maintained between substitutes?
Both modules are RoHS non-compliant and REACH unaffected. ECCN and HTSUS codes remain consistent.

Q5: Can both modules be mounted identically?
Both use Through Hole mounting and the Half Brick package style. Mechanical layout details should be matched for physical compatibility.
