Key Parameters
| Manufacturer Part Number | Series | Type | Number of Outputs | Voltage - Input (Min) | Voltage - Input (Max) | Voltage - Output 1 | Current - Output (Max) | Power (Watts) | Mounting Type | Package / Case | Size / Dimension | Operating Temperature | RoHS Status | Moisture Sensitivity Level (MSL) | REACH Status | ECCN |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| P045T048T17AL | VI Chip® PRM® (170W) | Pre-Regulator Module | 1 | 38V | 55V | 48V | 3.5A | 170 W | Through Hole | Module | 1.28" L x 0.87" W x 0.26" H (32.5mm x 22.0mm x 6.7mm) | -40°C ~ 125°C | ROHS3 Compliant | 5 (48 Hours) | REACH Unaffected | EAR99 |
Substitute Part Grouping Explanation
Substitution is determined strictly by matching the following key parameters: Pre-Regulator Module type, number of outputs, input voltage range (38V – 55V), output voltage (48V), through-hole mounting, identical package/case and physical dimensions, operating temperature range (-40°C to 125°C), RoHS and REACH status, and ECCN. Output current and power rating for substitutes may be equal to or higher than the original to ensure compatibility where these values are not exceeded in-system.

Engineering Selection Recommendations
The P045T048T17AL is obsolete and carries an MSL of 5 (48 hours), while the PRM48BT480T400B00 is an active component with MSL 4 (72 hours). Both devices are ROHS3 compliant and REACH unaffected, with identical ECCN status. Substitution can be performed based on package, compliance, and electrical compatibility as supplied in the input.
Frequently Asked Questions (FAQ)
Q1: What are the primary criteria for substituting the P045T048T17AL DC-DC converter?
A1: Substitute selection is based on matching type (Pre-Regulator Module), number of outputs, input voltage range, output voltage, mounting type, package/case, size/dimension, operating temperature range, and compliance parameters including RoHS, REACH, and ECCN.
Q2: Can the PRM48BT480T400B00 be used directly in place of the P045T048T17AL in through-hole assemblies?
A2: Yes. Both parts utilize through-hole mounting and share identical physical dimensions.
Q3: Are there differences in environmental or compliance status?
A3: Both models are ROHS3 compliant and REACH unaffected. The main difference is the Moisture Sensitivity Level (MSL): P045T048T17AL (5, 48 hours), PRM48BT480T400B00 (4, 72 hours).
Q4: Is there a difference in output current and power handling?
A4: Yes. The PRM48BT480T400B00 has higher output current (11A) and power rating (400W) compared to the P045T048T17AL (3.5A, 170W).
Q5: Is the substitute part within the same temperature rating as the original?
A5: Yes. Both parts are rated for operation from -40°C to 125°C.
Q6: Are there any concerns about package compatibility?
A6: Both parts have nearly identical module dimensions suitable for the same board layouts; note the original listing for PRM48BT480T400B00 as "16-DIP Module" for verification in system designs where socket type is relevant.
