Equivalent & Substitute Parts for Vicor Corporation VI-22J-EX

Part Overview

The Vicor Corporation VI-22J-EX is an isolated module DC-DC converter designed for ITE (Commercial) applications. It provides a single 36V output at up to 2.08A from a 21V–56V input voltage range, delivering 75W of output power in a full brick package. The module features over-current protection (OCP), over-temperature protection (OTP), over-voltage protection (OVP), and short-circuit protection (SCP), and it is specified with a 3 kV isolation voltage. The VI-22J-EX is classified as Obsolete, making it essential to identify strictly comparable substitute parts for design continuity, repair, or ongoing manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on parity in the following key electrical and mechanical parameters: input voltage range, output voltage and current ratings, power rating, isolation voltage, features, efficiency, operating temperature, mounting type, and package/case dimensions. All parameters must match exactly or be equivalent as specified for the full brick format and electrical compliance within the VI-200™ (75W) series. Only parts meeting these documented criteria are considered suitable substitutes.

Key parameters used for grouping:

• Voltage - Input (Min/Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Voltage - Isolation
• Features (OCP, OTP, OVP, SCP)
• Operating Temperature
• Efficiency
• Mounting Type
• Package / Case
• Size / Dimension
• RoHS Status

Parameter Comparison

Engineering Selection Recommendations

Selection between VI-22J-EX and VI-22J-EX-B1 should be based on product lifecycle status, compliance, and availability. VI-22J-EX is listed as Obsolete, whereas VI-22J-EX-B1 is listed as Active. Both parts are RoHS non-compliant. There is no difference in moisture sensitivity or REACH status. ECCN and HTSUS are identical.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting VI-22J-EX with VI-22J-EX-B1?
A1: Electric and mechanical parameters including input voltage range, output voltage, output current, power, isolation voltage, features, efficiency, package type, mounting style, and series must match for direct substitution.

Q2: Is the form factor equivalent between VI-22J-EX and VI-22J-EX-B1?
A2: Both use a full brick package with the same length and width. Only the height differs (0.50" for VI-22J-EX and 1.07" for VI-22J-EX-B1).

Q3: Are there any differences in environmental or compliance status?
A3: Both are RoHS non-compliant and REACH unaffected. Both share the same ECCN and HTSUS codes.

Q4: Will the mounting method change when using VI-22J-EX-B1?
A4: Both have through-hole mounting; no change in board-level mounting requirements.

Q5: Does the product status affect long-term availability?
A5: VI-22J-EX is Obsolete; VI-22J-EX-B1 is Active. Selection should be based on the required product status for procurement and supply chain management.

Q6: Are electrical protections (OCP, OTP, OVP, SCP) consistent between the parts?
A6: Both have identical protection features as explicitly specified.
