Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching all functional and mechanical parameters. Key substitution criteria include identical input voltage range (55V – 100V), output voltage (95V), output current (1.58A), total power (150W), voltage isolation (3kV), features (OCP, OTP, OVP, SCP), form factor (Full Brick), mounting type (Through Hole), and operating temperature range (−25°C to 85°C). Package outline and regulatory compliance fields are also included. Only models meeting all these parameters are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part, Vicor VI-B4B-CV, is obsolete. The substitute part VI-B4B-CV-B1 is active and meets all key functional and mechanical parameters. Both parts are RoHS non-compliant and REACH unaffected. The form factor is Full Brick for both models; however, dimensional variance exists in height. No compliance deviation is present within the parameters provided.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting VI-B4B-CV?
A1: Substitution requires exact matching of input voltage range, output voltage, output current, power rating, isolation voltage, feature set, operating temperature, mounting style, package type, and mechanical dimensions, as well as matching compliance status.

Q2: Can VI-B4B-CV-B1 fully replace VI-B4B-CV in an existing PCBA?
A2: VI-B4B-CV-B1 meets all functional and electrical specifications. The only dimensional difference is height; both use the Full Brick package and through-hole mounting.

Q3: Are there compliance differences between these parts?
A3: Both are RoHS non-compliant and REACH unaffected, with the same regulatory declarations per provided data.

Q4: Does the difference in package height affect substitution suitability?
A4: Both parts are Full Brick packages and through-hole mounted; the height increase on VI-B4B-CV-B1 should be evaluated in mechanical design, as all other parameters match.

Q5: Is the substitute part currently available?
A5: VI-B4B-CV-B1 is active per its status and listed as in inventory.
