Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D25K25R is determined by strict equivalence across the following critical parameters:

• Resistance value: 25 Ohms
• Power rating: 25 W
• Tolerance: ±10%
• Adjustment type: Slide
• Mounting configuration: Chassis Mount
• Termination style: Solder Lug
• Package type: Radial, 3 Lead, Tubular
• Physical length: 2.000" (50.80mm)
• Mechanical dimensions: Diameter within tolerance of 0.563" OD, 0.313" ID

All identified substitute parts meet these criteria and maintain functional and mechanical compatibility with the original D25K25R specification.

Engineering Selection Recommendations

D25K25RE (Ohmite): This direct Ohmite equivalent maintains identical electrical and mechanical specifications to the D25K25R while offering ROHS3 compliance. Selection of D25K25RE is appropriate for applications requiring RoHS3 certification or when procurement from the same manufacturer series is preferred.

AVT02506E25R00KE (Vishay Huntington Electric Inc.): This Vishay alternative provides functional equivalence with ROHS3 compliance. Mechanical dimensions vary minimally (0.559" OD and 0.311" ID versus 0.563" OD and 0.313" ID), remaining within acceptable tolerance for chassis mount applications. Selection is appropriate for cross-manufacturer sourcing strategies or when Vishay component availability is prioritized.

Frequently Asked Questions (FAQ)

Q: Can D25K25RE be used as a direct replacement for D25K25R? A: Yes. D25K25RE is electrically and mechanically identical to D25K25R, with the primary difference being ROHS3 compliance status. Both components share the same Dividohm®210 series designation and are manufactured by Ohmite.

Q: What are the mechanical tolerance differences between D25K25R and AVT02506E25R00KE? A: The AVT02506E25R00KE has a slightly smaller outer diameter (0.559" versus 0.563") and inner diameter (0.311" versus 0.313"). These differences are within acceptable mechanical tolerances for chassis mount applications and do not affect electrical performance or functional compatibility.

Q: Are all substitute parts RoHS compliant? A: D25K25RE and AVT02506E25R00KE are both ROHS3 compliant. The original D25K25R is RoHS non-compliant. Selection should be based on application compliance requirements.

Q: Can these parts be used interchangeably in existing designs? A: Yes, all three parts are functionally equivalent for applications requiring 25 Ohm, 25 Watt slide adjustable power resistors with chassis mount configuration. Mechanical dimensions are compatible with standard chassis mount installations.

Q: What is the difference between the Ohmite and Vishay options? A: Both manufacturers provide equivalent electrical performance and RoHS3 compliance. The primary differences are manufacturer series designation (Dividohm®210 versus AVT) and minor mechanical dimensions. Selection may be based on supplier availability, lead time, or procurement strategy.
