Substitute Part Grouping Explanation

Substitute parts for the HS150 20R F are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match exactly for a part to qualify as a direct substitute:

• Resistance value: 20 Ohms
• Tolerance: ±1%
• Power rating: 150W
• Composition: Wirewound
• Temperature coefficient: ±100ppm/°C
• Housing material: Aluminum
• Mounting configuration: Flanges with solder lugs
• Package classification: Axial, Box

The substitute parts listed below meet all these criteria and belong to the same ARCOL HS series product family.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS150 20R F and ARCOL HS150 20R F are active production components with full RoHS compliance. The Ohmite variant carries ROHS3 certification, while the ARCOL variant carries standard RoHS certification. Both parts are classified under ECCN EAR99 for export control purposes. Selection between these equivalents should be based on supply chain requirements, inventory availability, and specific compliance documentation needed for your application. The ARCOL variant includes pulse withstanding capability as an additional feature. Both parts maintain identical electrical performance and mechanical fit within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS150 20R F be used as a direct replacement for the Ohmite HS150 20R F?

A: Yes. Both parts share identical electrical specifications (20 Ohms ±1%, 150W, ±100ppm/°C) and mechanical dimensions (3.846" L × 0.949" H seated). They are parametrically equivalent and interchangeable in circuit applications.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 represents the most current RoHS directive implementation. Both certifications indicate compliance with hazardous substance restrictions. The specific version may affect regulatory documentation requirements for your end application.

Q: Are there dimensional differences between the substitute parts?

A: The length and seated height are identical at 3.846" (97.70mm) and 0.949" (24.10mm) respectively. The width dimension differs: Ohmite variant is 1.075" (27.30mm), while ARCOL variant is 1.870" (47.50mm). Verify mounting space availability before selection.

Q: What does "pulse withstanding" mean on the ARCOL variant?

A: This feature indicates the component can withstand transient overvoltage or overcurrent pulses beyond steady-state ratings. This capability is provided by ARCOL but not specified for the Ohmite variant in the available data.

Q: Are both parts suitable for high-temperature applications?

A: Both parts operate with a temperature coefficient of ±100ppm/°C. Specific operating temperature limits are not provided in the available specifications. Consult detailed datasheets for thermal performance curves and maximum operating temperature ratings.
