MI-26Y-MX Equivalent & Substitute Parts Reference
Part Overview
The Vicor Corporation MI-26Y-MX is an isolated DC-DC converter module designed for ITE (Commercial) applications, delivering a single 3.3V output at up to 15A from a 125V to 400V input range. It features remote on/off, OCP, OTP, and OVP protections, and is structured in a full brick, through-hole package. The product is classified as obsolete, making the identification of substitute parts necessary for maintenance, design continuity, and long-term support in existing systems.

Substitute Part Grouping Explanation
Substitute parts are grouped strictly according to matching operational electrical and mechanical parameters. The following criteria are used for equivalence:
- Manufacturer and series: identical
- Function: isolated DC-DC converter module
- Input voltage range: 125V to 400V
- Output voltage: 3.3V
- Output current: up to 15A
- Output power: 50W
- Isolation voltage: 3 kV
- Number of outputs: 1
- Package type: full brick
- Mounting type: through hole
- Operating temperature range: -55°C to 85°C
- Feature set: Remote On/Off, OCP, OTP, OVP
- Compliance statuses: RoHS, REACH, ECCN, and HTSUS as provided
Inclusion in the substitute part list is determined only by explicit matching or equivalence across these specified fields.

Engineering Selection Recommendations
The MI-26Y-MX is identified as obsolete. For ongoing engineering support and production, selection of an active substitute model such as MI-26Y-MX-F1 is required to ensure product availability and lifecycle support. Both models are classified as RoHS non-compliant and unaffected by REACH, with equivalent ECCN and HTSUS identifiers. Mechanical differences in height should be considered for physical integration. Inventory levels are included for reference.
Frequently Asked Questions (FAQ)
Q1: What determines a valid substitute for MI-26Y-MX in the DC-DC converter category?
Substitution is determined strictly by matching input/output voltages, output current, power rating, isolation voltage, form factor, mounting type, feature set, and compliance statuses.
Q2: Are there any differences in form factor between MI-26Y-MX and MI-26Y-MX-F1?
Both are full brick modules with identical length and width; the MI-26Y-MX-F1 has a greater height (0.75" vs. 0.50").
Q3: Are both modules compatible for ITE (Commercial) applications?
Both modules are specified for ITE (Commercial) applications.
Q4: What is the RoHS and REACH compliance status for both products?
Both MI-26Y-MX and MI-26Y-MX-F1 are RoHS non-compliant and REACH unaffected.
Q5: Does the operating temperature range differ between the main and substitute models?
Both modules support an operating temperature range of -55°C to 85°C.
Q6: Are there any feature differences between the MI-26Y-MX and MI-26Y-MX-F1?
Both modules provide Remote On/Off, OCP, OTP, and OVP features.
Q7: How should mechanical differences be considered when replacing MI-26Y-MX with MI-26Y-MX-F1?
Ensure that integration requirements accommodate the increased height of MI-26Y-MX-F1. Length and width remain unchanged.
