D100K50R Equivalent & Substitute Parts

Part Overview

The D100K50R is a 50 Ohm, 100 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 and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative compliance certifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D100K50R is determined by strict equivalence across the following critical parameters:

• Resistance value: 50 Ohms
• Power rating: 100 W
• Adjustment mechanism: Slide adjustable
• Mounting configuration: Chassis mount
• Termination style: Solder lug
• Package type: Radial, 3 lead, tubular
• Tolerance: ±10%

Mechanical dimensions (outer diameter, inner diameter, and length) must remain within the specified tolerances to ensure proper fit in existing designs. All identified substitutes meet these core electrical and mechanical requirements. Compliance certifications and packaging formats may vary between manufacturers and are noted separately.

Parameter Comparison

Engineering Selection Recommendations

All three parts—D100K50R, AVT10006E50R00KE, and D100K50RE—are active production components meeting the core electrical and mechanical specifications for 50 Ohm, 100 W slide adjustable power resistors with chassis mount configuration.

The D100K50RE (Ohmite) is functionally identical to the D100K50R with matching dimensions and series designation. The primary distinction is RoHS3 compliance status; D100K50RE meets ROHS3 requirements while D100K50R does not. Both are packaged in bulk format.

The AVT10006E50R00KE (Vishay Huntington Electric Inc.) provides an alternative from a different manufacturer. Mechanical dimensions are nominally equivalent with minor tolerance variations (outer diameter 0.748" versus 0.752", length 6.496" versus 6.500"). This part achieves ROHS3 compliance and carries MSL rating of 1 (Unlimited). Selection between Ohmite and Vishay variants depends on supply chain requirements, compliance mandates, and established qualification protocols.

Frequently Asked Questions (FAQ)

Q: Can AVT10006E50R00KE be used as a direct replacement for D100K50R?

A: Yes. Both parts meet the electrical specifications (50 Ohms, 100 W, ±10% tolerance, slide adjustment) and mechanical requirements (chassis mount, solder lug termination, radial 3-lead tubular package). Outer diameter tolerance variation (0.748" versus 0.752") and length tolerance variation (6.496" versus 6.500") fall within acceptable mechanical clearance for standard chassis mount applications. Verify mounting hole spacing and clearance in your specific design before implementation.

Q: What is the difference between D100K50R and D100K50RE?

A: Both are Ohmite Dividohm®210 series components with identical electrical and mechanical specifications. The primary difference is RoHS compliance: D100K50RE is ROHS3 compliant while D100K50R is not. D100K50RE also carries REACH Unaffected status. If RoHS3 compliance is required, D100K50RE is the appropriate selection.

Q: Are there packaging differences between these substitutes?

A: D100K50R is supplied in standard packaging format. D100K50RE and AVT10006E50R00KE are supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: What compliance certifications apply to these parts?

A: All three parts carry EAR99 export classification and HTSUS code 8533.39.0080. RoHS compliance differs: D100K50R is non-compliant, while D100K50RE and AVT10006E50R00KE are ROHS3 compliant. AVT10006E50R00KE carries MSL rating 1 (Unlimited); moisture sensitivity is not applicable for D100K50R and D100K50RE.

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

A: Electrical interchangeability is confirmed across all three parts. Mechanical interchangeability requires verification of mounting hole spacing, clearance tolerances, and thermal management provisions in your specific application. Minor dimensional variations (approximately 0.004" outer diameter, 0.004" length) between Ohmite and Vishay variants are typically accommodated in standard chassis mount designs but should be confirmed during design review.
