D225K150 Equivalent & Substitute Parts

Part Overview

The D225K150 is a 150 Ohm, 225 W slide adjustable power resistor manufactured by Ohmite in the Dividohm®210 series. This chassis mount component features a radial, 3-lead tubular package with solder lug termination and dimensions of 1.126" OD × 0.752" ID, 10.500" length. The part is currently active in production. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or when design requirements permit alternative manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D225K150 are qualified based on matching the following critical parameters: resistance value (150 Ohms), power rating (225 W), tolerance (±10%), adjustment type (Slide), mounting configuration (Chassis Mount), termination style (Solder Lug), and package type (Radial, 3 Lead, Tubular). Mechanical dimensions including outer diameter, inner diameter, and length must remain within the specified tolerances to ensure proper fit in existing mechanical assemblies and thermal management requirements. All identified substitutes meet these criteria and are manufactured by established component suppliers.

Parameter Comparison

Engineering Selection Recommendations

The D225K150E from Ohmite is the primary direct equivalent, maintaining identical electrical specifications, mechanical dimensions, and series designation while offering ROHS3 compliance. This part is recommended when RoHS compliance is required for new designs or when regulatory requirements mandate compliant components.

The AVT20020E150R0KE from Vishay Huntington Electric Inc. is a functional equivalent meeting all electrical specifications and core mechanical requirements. Minor dimensional variations exist in inner diameter (0.748" versus 0.752") and length (10.512" versus 10.500"), which remain within acceptable mechanical tolerances for chassis mount applications. This part is suitable for applications where multi-source qualification is required or when Ohmite supply is constrained. ROHS3 compliance is confirmed; REACH status is vendor undefined.

Both substitute parts are active production components with confirmed inventory availability and are suitable for direct replacement in applications where the D225K150 is specified.

Frequently Asked Questions (FAQ)

Q: Can D225K150E be used as a direct replacement for D225K150? A: Yes. The D225K150E maintains identical electrical parameters (150 Ohms, 225 W, ±10% tolerance), adjustment type (Slide), mounting configuration (Chassis Mount), termination (Solder Lug), and mechanical dimensions. The primary difference is RoHS3 compliance status. Both parts are from the same manufacturer and series.

Q: What are the dimensional differences between D225K150 and AVT20020E150R0KE? A: Inner diameter differs by 0.004" (0.752" versus 0.748") and length differs by 0.012" (10.500" versus 10.512"). These variations are within acceptable mechanical tolerances for chassis mount applications and do not affect electrical performance or thermal characteristics.

Q: Are all three parts mechanically interchangeable? A: Yes. All three parts share identical outer diameter (1.126"), mounting type (Chassis Mount), termination style (Solder Lug), and package configuration (Radial, 3 Lead, Tubular). Minor inner diameter and length variations in the Vishay part remain within acceptable tolerances for mechanical fit and thermal management.

Q: What is the significance of RoHS compliance differences? A: The D225K150 is RoHS non-compliant, while D225K150E and AVT20020E150R0KE are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating compliant components, the D225K150E or AVT20020E150R0KE must be selected.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the design does not impose constraints that conflict with the minor dimensional variations noted for the Vishay part. All three parts deliver identical electrical performance and are suitable for the same circuit applications.
