Substitute Part Grouping Explanation

The substitute part grouping for P045T048T32AL is determined strictly by matching core electrical and mechanical parameters as provided. These include input voltage range, output voltage, maximum output current (or higher), number of outputs, package and mounting type, size/dimensions, thermal range, features, compliance status, and application category. A valid substitute must match or exceed the electrical fit and maintain physical/mechanical compatibility.

Key parameters for substitution:

• Input Voltage Range
• Output Voltage
• Max Output Current (≥ required value)
• Number of Outputs
• Mounting Type & Package Dimensions
• Operating Temperature Range
• Compliance (RoHS3, REACH)
• Application Category

Parameter Comparison

Engineering Selection Recommendations

For the P045T048T32AL, the active Vicor PRM48BT480T400B00 is a valid substitute based strictly on product status and provided environmental compliance (RoHS3, REACH Unaffected). When the main part is obsolete, only active or available parts with the same compliance credentials are appropriate for assurance of continued availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a valid substitute in this DC-DC pre-regulator module category?
A1: Input voltage range, output voltage, output current (equal or higher), number of outputs, mounting type, package dimensions, operating temperature range, and compliance status.

Q2: Is the mechanical footprint identical between P045T048T32AL and PRM48BT480T400B00?
A2: Yes, both parts have the same specified size and dimension: 1.28" L x 0.87" W x 0.26" H (32.5mm x 22.0mm x 6.7mm).

Q3: Can PRM48BT480T400B00 replace P045T048T32AL in the same PCB footprint?
A3: Based on the given mounting type (Through Hole) and identical package dimensions, the replacement does not require changes to the PCB footprint.

Q4: Does the substitute part meet current RoHS and REACH compliance requirements?
A4: Yes; both parts are specified as ROHS3 Compliant and REACH Unaffected.

Q5: Do features differ between the parts and is feature difference a factor in this substitution?
A5: Both parts provide UVLO; the substitute offers additional features (OCP, OTP, OVP, SCP) but the substitution grouping is determined by core electrical and mechanical compatibility and compliance, based only on provided parameters.
