Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules for the Vicor P045F048T17AL are selected strictly based on the following permitted parameters: input voltage range (38V–55V), output voltage (48V), number of outputs (1), surface mount module package, size and dimensions, operating temperature range, RoHS compliance status, and moisture sensitivity level (MSL). The substitute must match or exceed these parameters to ensure form, fit, and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Vicor P045F048T17AL and PRM48BF480T400B00 are RoHS3 compliant and REACH unaffected, supporting surface mount placement in identical module packages and physical dimensions. The substitute (PRM48BF480T400B00) remains active in production, offering a higher output current and power. MSL differs (MSL 5 vs. MSL 4), which must be considered for manufacturing process adjustment but does not affect the basic form and fit. Substitute selection is constrained by the product being obsolete, requiring transitions only to models with matching compliance and certifications.

Frequently Asked Questions (FAQ)

Q1: What are the key parameters that must match for selecting a substitute in the DC-DC converter module category?
A1: Input voltage range, output voltage, package type, mounting method, output count, operating temperature range, form factor, RoHS status, and MSL must match or be compatible.

Q2: Is PRM48BF480T400B00 a direct substitute for P045F048T17AL?
A2: PRM48BF480T400B00 matches all critical electrical and mechanical parameters, including input/output ranges and package dimensions, and exceeds the current and power ratings.
