Equivalent & Substitute Parts for D225K2R0

Part Overview

The D225K2R0 is a 2 Ohm, 225 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. Alternative equivalent parts may be required due to packaging availability, compliance requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitutes for the D225K2R0 are determined by matching the following critical parameters: resistance value (2 Ohms), power rating (225 W), tolerance (±10%), adjustment type (Slide), mounting configuration (Chassis Mount), termination style (Solder Lug), and package form (Radial, 3 Lead, Tubular). Physical dimensions must remain within acceptable mechanical tolerances for chassis mount applications. All identified substitutes maintain these core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

D225K2R0E (Ohmite) is a direct equivalent substitute with identical electrical and mechanical specifications. This part maintains the same Dividohm®210 series design and achieves ROHS3 compliance, differing only in packaging format (Bulk versus standard packaging).

AVT20020E2R000KE (Vishay Huntington Electric Inc.) is a functional equivalent with matching electrical specifications and ROHS3 compliance. Minor dimensional variations exist: the inner diameter is 0.748" (19.00mm) versus 0.752" (19.10mm), and the length is 10.512" (267.00mm) versus 10.500" (266.70mm). These differences remain within acceptable mechanical tolerances for chassis mount applications.

Frequently Asked Questions (FAQ)

Q: Can D225K2R0E replace D225K2R0 in existing designs? A: Yes. D225K2R0E maintains identical electrical and mechanical specifications with the same series designation. The primary difference is packaging format.

Q: What are the dimensional tolerances for mechanical compatibility? A: The AVT20020E2R000KE exhibits minor dimensional variations: inner diameter difference of 0.004" (0.10mm) and length difference of 0.012" (0.30mm). These variations are within typical chassis mount mechanical tolerances.

Q: Are there compliance differences between the substitutes? A: D225K2R0 is RoHS non-compliant. Both D225K2R0E and AVT20020E2R000KE are ROHS3 compliant, making them suitable for applications requiring RoHS compliance.

Q: Do all substitutes use the same termination method? A: Yes. All three parts feature solder lug termination in a radial, 3 lead, tubular configuration.

Q: What determines substitutability for this resistor category? A: Substitutability is determined by matching resistance (2 Ohms), power rating (225 W), tolerance (±10%), adjustment type (Slide), mounting configuration (Chassis Mount), termination style (Solder Lug), and package form (Radial, 3 Lead, Tubular). Physical dimensions must remain within acceptable mechanical tolerances.
