Substitute Part Grouping Explanation

Substitute parts for the D225K3R0 are identified based on strict equivalence of electrical and mechanical parameters. The following criteria determine substitutability:

• Resistance value: 3 Ohms (exact match required)
• Power rating: 225 W (exact match required)
• Tolerance: ±10% (exact match required)
• Adjustment type: Slide (exact match required)
• Mounting configuration: Chassis Mount (exact match required)
• Termination style: Solder Lug (exact match required)
• Package type: Radial, 3 Lead, Tubular (exact match required)
• Physical dimensions: Outer diameter 1.126" (28.60mm) and length within 10.500" to 10.512" (266.70mm to 267.00mm) range

The AVT20020E3R000KE from Vishay Huntington Electric Inc. meets all substitution criteria with dimensional tolerance within acceptable engineering limits.

Parameter Comparison

Engineering Selection Recommendations

The AVT20020E3R000KE carries ROHS3 compliance status, whereas the D225K3R0 is non-compliant. Both components share the same ECCN and HTSUS classifications. Selection between these parts should consider regulatory requirements, supply availability, and application-specific compliance mandates. Both parts maintain Active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the AVT20020E3R000KE replace the D225K3R0 in existing designs?

A: Yes. The AVT20020E3R000KE meets all electrical and mechanical substitution criteria, including resistance, power rating, tolerance, adjustment type, mounting configuration, and package style. Dimensional variations (inner diameter 0.748" vs. 0.752" and length 10.512" vs. 10.500") fall within acceptable engineering tolerances for chassis mount applications.

Q: What is the primary difference between these two parts?

A: The primary difference is RoHS compliance status. The AVT20020E3R000KE is ROHS3 compliant, while the D225K3R0 is non-compliant. Electrical and mechanical performance are equivalent.

Q: Are there any dimensional concerns with substitution?

A: Inner diameter and length show minor variations within 0.004" and 0.012" respectively. These differences are negligible for standard chassis mount applications and do not affect electrical performance or mechanical fit in typical circuit designs.

Q: Do both parts use the same termination method?

A: Yes. Both the D225K3R0 and AVT20020E3R000KE use solder lug termination, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What certifications apply to both parts?

A: Both parts are classified under ECCN EAR99 and HTSUS 8533.39.0080. The AVT20020E3R000KE additionally carries ROHS3 compliance certification.
