Key Parameters

Substitute Part Grouping Explanation

Substitute part selection in the DC DC converter category is based strictly on identical key parameters: electrical performance (input voltage range, output voltage and current, output power, isolation voltage, efficiency), mechanical form factor (package/case, size/dimension, mounting type), operating temperature range, relevant features, compliance status, certifications, and series compatibility. Only substitute models with matching specifications as listed above are suitable for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The Vicor VI-22W-EX DC DC converter is Obsolete. The VI-22W-EX-B1 from Vicor Corporation, with Active product status, matches all specified electrical, mechanical, and compliance parameters. Both models are RoHS non-compliant and REACH unaffected, with identical ECCN and HTSUS codes. The mechanical envelope differs only in height (0.50" vs. 1.07"), requiring attention to clearance in the application.

Frequently Asked Questions (FAQ)

Q: What key electrical parameters are required to qualify a substitute for VI-22W-EX?
A: Input voltage range (21V to 56V), output voltage (5.5V), output current (13.64A), output power (75W), and isolation voltage (3 kV) must match exactly.

Q: Are these substitute modules compatible in circuit design and PCB layout?
A: Both use the Full Brick package and through-hole mounting. The only dimensional variance is enclosure height. Ensure vertical clearance supports the alternate module.

Q: Are there any differences in compliance certifications between the main and substitute part?
A: Both are RoHS non-compliant, have Not Applicable MSL, are REACH unaffected, and share ECCN (EAR99) and HTSUS (8504.40.9580).

Q: Is thermal performance or operating temperature range affected by substitution?
A: Both modules have an operating temperature range of -10°C to 85°C and efficiency specified at 88%.

Q: Can the substitute be used in ITE (Commercial) applications?
A: The substitute, VI-22W-EX-B1, specifies the same application category: ITE (Commercial).

Q: Does the substitute module offer all original protection features?
A: Yes. Both include OCP (Over Current Protection), OTP (Over Temperature Protection), OVP (Over Voltage Protection), and SCP (Short Circuit Protection).

Q: Is the substitute compatible with existing inventory and procurement codes?
A: The procurement codes (ECCN, HTSUS) are identical for both modules. Existing commercial documentation should remain consistent.
