Ohmite HS50 10K F Equivalent & Substitute Parts

Part Overview

The Ohmite HS50 10K F is a 50-watt wirewound chassis mount resistor with 10 kOhms resistance and ±1% tolerance. This active product is designed for applications requiring high power dissipation with precision resistance values. Substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application needs where alternative specifications remain functionally compatible.

Substitute Part Grouping Explanation

Substitute parts for the HS50 10K F are classified based on electrical and mechanical compatibility:

Direct Electrical Equivalent (850F10KE - ARCOL Metal-Mite®89): This substitute maintains identical resistance (10 kOhms), tolerance (±1%), power rating (50W), composition (wirewound), housing type (aluminum), mounting features (flanges), and lead style (solder lugs). Physical dimensions are identical. The temperature coefficient differs slightly (±20ppm/°C vs. 25ppm/°C), remaining within acceptable precision parameters for most applications.

Parametric Equivalent (HS25 10K F - Ohmite): This substitute shares the same manufacturer (Ohmite), resistance value (10 kOhms), tolerance (±1%), composition (wirewound), housing type (aluminum), mounting features (flanges), and lead style (solder lugs). The power rating is reduced to 25W, making this suitable only for applications where the lower power dissipation requirement is acceptable. Physical dimensions are smaller due to the reduced power rating.

Parameter Comparison

Engineering Selection Recommendations

850F10KE (ARCOL Metal-Mite®89): This direct equivalent is suitable for applications requiring full replacement of the HS50 10K F. Both parts are active products with RoHS compliance. The ARCOL substitute maintains identical electrical specifications and physical dimensions, with a marginally lower temperature coefficient that does not compromise precision requirements. This part is recommended for direct substitution where inventory or lead time constraints apply.

HS25 10K F (Ohmite): This parametric equivalent is suitable only for applications where the power dissipation requirement does not exceed 25W. The reduced physical size may require circuit board layout modifications. Both parts are active products with RoHS compliance (ROHS3 for the HS25 10K F). This substitute is not recommended for applications requiring the full 50W power rating of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 850F10KE directly replace the HS50 10K F? A: Yes. The 850F10KE maintains identical resistance (10 kOhms), tolerance (±1%), power rating (50W), composition (wirewound), housing type (aluminum), mounting features (flanges), lead style (solder lugs), and physical dimensions. Both are active products with RoHS compliance.

Q: What is the key difference between the HS50 10K F and HS25 10K F? A: The primary difference is power rating: 50W versus 25W. The HS25 10K F has smaller physical dimensions (1.075" L x 0.559" W versus 1.933" L x 1.102" W). Both share identical resistance, tolerance, composition, and mounting features. The HS25 10K F is suitable only for applications with power dissipation requirements of 25W or less.

Q: Are there packaging differences between substitutes? A: The HS50 10K F is supplied in Box packaging, while the 850F10KE is supplied in Bulk packaging. The HS25 10K F is also supplied in Bulk packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: Do temperature coefficient differences affect substitution? A: The HS50 10K F has a temperature coefficient of 25ppm/°C, the 850F10KE has ±20ppm/°C, and the HS25 10K F has ±25ppm/°C. These variations are within acceptable precision parameters for most applications and do not prevent substitution based on this parameter alone.

Q: Which substitute is recommended for space-constrained applications? A: The HS25 10K F offers a smaller footprint (1.075" L x 0.559" W) compared to the HS50 10K F (1.933" L x 1.102" W). However, this substitute is only suitable if the application power requirement does not exceed 25W.
