Equivalent & Substitute Parts for D50K25R

Part Overview

The D50K25R is a 25 Ohm, 50 W slide adjustable power resistor manufactured by Ohmite in the Dividohm®210 series. This chassis mount component features a tubular radial design with solder lug termination and is classified as Active product status. Alternative equivalent parts are necessary to support procurement flexibility, inventory management, and compliance requirements across different supply channels and manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D50K25R is determined by strict equivalence across the following critical parameters:

• Resistance value: 25 Ohms
• Power rating: 50 W
• Tolerance: ±10%
• Adjustment type: Slide
• Mounting configuration: Chassis Mount
• Termination style: Solder Lug
• Package type: Radial, 3 Lead, Tubular

Mechanical dimensions (diameter and length) must remain within the specified tolerances to ensure proper fit in existing circuit board layouts and mechanical assemblies. All substitute parts listed maintain these core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical electrical specifications (25 Ohms, 50 W, ±10% tolerance) and adjustment characteristics (slide type). Mechanical dimensions are equivalent within standard manufacturing tolerances.

The D50K25RE (Ohmite) is a direct manufacturer equivalent with ROHS3 compliance, offering improved environmental compliance over the original D50K25R while maintaining identical form factor and performance characteristics.

The AVT05006E25R00KE (Vishay Huntington Electric Inc.) provides an alternative from a different manufacturer with ROHS3 compliance. Mechanical dimensions show minor variations (0.559" OD vs. 0.563" OD; 4.016" length vs. 4.000" length), which remain within acceptable tolerances for standard chassis mount applications.

Selection between these parts should be based on procurement availability, supply chain requirements, and compliance mandates specific to the application.

Frequently Asked Questions (FAQ)

Q: Can D50K25RE be used as a direct replacement for D50K25R?

A: Yes. Both parts are manufactured by Ohmite in the Dividohm®210 series with identical electrical ratings (25 Ohms, 50 W, ±10%), adjustment type (slide), mounting configuration (chassis mount), and physical dimensions. The primary difference is RoHS compliance status.

Q: What are the mechanical tolerance differences between D50K25R and AVT05006E25R00KE?

A: The AVT05006E25R00KE has a slightly smaller outer diameter (0.559" vs. 0.563") and a marginally longer length (4.016" vs. 4.000"). These variations are within standard manufacturing tolerances for tubular chassis mount resistors and do not affect electrical performance or standard mounting applications.

Q: Are all three parts electrically interchangeable?

A: Yes. All three parts share identical electrical specifications: 25 Ohms resistance, 50 W power rating, ±10% tolerance, and slide adjustment type. Electrical performance and circuit behavior are equivalent.

Q: What is the significance of RoHS compliance differences?

A: The D50K25R is RoHS non-compliant, while D50K25RE and AVT05006E25R00KE are ROHS3 compliant. RoHS compliance is a regulatory requirement in many markets and applications. Selection depends on end-use requirements and regional compliance mandates.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the mechanical envelope accommodates the minor dimensional variations noted for the Vishay part. The Ohmite D50K25RE is a direct form-fit-function replacement. The Vishay AVT05006E25R00KE requires verification that the 0.004" length difference and 0.004" diameter reduction do not conflict with mechanical constraints in the specific application.
