D50K10R Equivalent & Substitute Parts

Part Overview

The D50K10R is a 10 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 currently in active production status. Equivalent parts are identified when identical electrical specifications and mechanical form factors are required for direct replacement in existing designs or when sourcing alternatives from different manufacturers becomes necessary due to inventory constraints or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D50K10R is determined by strict equivalence across the following parameters:

• Resistance value: 10 Ohms
• Power rating: 50 W
• Tolerance: ±10%
• Adjustment mechanism: Slide adjustable
• Mounting configuration: Chassis mount
• Termination style: Solder lug
• Package form: Radial, 3 lead, tubular

Mechanical dimensions must remain within acceptable tolerances to ensure proper fit in existing mounting hardware and PCB layouts. The AVT05006E10R00KE from Vishay Huntington Electric Inc. meets all electrical and mechanical criteria for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the D50K10R and AVT05006E10R00KE are active production components with identical electrical specifications. The AVT05006E10R00KE offers ROHS3 compliance, which may be required for applications subject to RoHS regulations. Mechanical dimensions between the two parts are equivalent within standard manufacturing tolerances, with dimensional variations of less than 0.01" in diameter and 0.016" in length. Selection between these parts should be based on regulatory compliance requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can the AVT05006E10R00KE replace the D50K10R in existing designs?

A: Yes. Both components share identical electrical specifications (10 Ohms, 50 W, ±10% tolerance) and mechanical form factors (slide adjustable, chassis mount, solder lug termination, radial 3-lead tubular package). Dimensional variations are within acceptable tolerances for standard mounting applications.

Q: What is the significance of RoHS compliance differences?

A: The D50K10R is RoHS non-compliant, while the AVT05006E10R00KE is ROHS3 compliant. Applications subject to RoHS regulations or customer requirements must use the ROHS3 compliant part.

Q: Are the mechanical dimensions interchangeable?

A: The parts are mechanically compatible. The AVT05006E10R00KE has a diameter of 0.559" OD versus 0.563" OD for the D50K10R, and a length of 4.016" versus 4.000". These differences are within standard manufacturing tolerances and do not affect chassis mount compatibility.

Q: What parameters must remain constant for substitution?

A: Resistance value, power rating, tolerance, adjustment type, mounting type, termination style, and package form must all remain identical. Mechanical dimensions must be compatible with existing mounting hardware.
