Equivalent & Substitute Parts for PMR8210P

Part Overview

The PMR8210P, manufactured by Flex Power Modules, is a non-isolated PoL (Point-of-Load) DC-DC converter module designed for ITE (Commercial) applications. It provides a single adjustable output of 3 to 5.25V at up to 40A, with an input voltage range of 8V to 14V and a maximum power output of 210W. The module is configured for through-hole mounting in a 22-DIP package and supports features such as remote on/off and remote sense. The PMR8210P has reached obsolete status, making the identification of alternative or substitute models necessary for ongoing designs and maintenance.

Engineering Selection Recommendations

The PMR8210P is classified as obsolete. The PTH08T255WAD from Texas Instruments shares the same non-isolated PoL module type, input and output voltage ranges, output current, mounting method, package, and environmental compliance statuses including RoHS3 and REACH. Both parts are suitable for ITE (Commercial) applications and have comparable operating temperature ranges and moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q1: What determines if PTH08T255WAD can be used in place of PMR8210P?
A1: Substitution is determined by matching input voltage range (8V–14V), output voltage (3–5.25V), output current capability (40A), mounting type (Through Hole, 22-DIP Module), application suitability, and compliance standards (RoHS3, REACH).

Q2: Are the mechanical sizes of PMR8210P and PTH08T255WAD compatible?
A2: Both modules have a size of 1.52" L x 1.02" W x 0.38" H, facilitating direct replacement in existing footprints.

Q3: Do both modules have the same moisture sensitivity and environmental compliance?
A3: Both modules are specified as Not Applicable for moisture sensitivity level (MSL) and are REACH unaffected and ROHS3 compliant.

Q4: Is there any difference in efficiency or operating temperature?
A4: The PMR8210P has an efficiency of 95.6% and an operating temperature of -40°C ~ 85°C with derating. The PTH08T255WAD has an efficiency of 95% and operates across -40°C ~ 85°C.

Q5: Does the package type ensure easy drop-in replacement?
A5: Both parts use the 22-DIP Module through-hole package, supporting direct substitution without mechanical or pinout changes based on supplied data.
