Substitute Part Grouping Explanation

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

Direct Electrical Equivalent (850F10KE): Matches resistance value (10 kOhms), tolerance (±1%), and power rating (50W). Composition, housing type, and mounting features are identical. Temperature coefficient differs by 5ppm/°C (±20ppm/°C vs. ±25ppm/°C), which remains within acceptable tolerance for most applications. Mechanical dimensions vary in width (28.00mm vs. 14.20mm), requiring verification of mounting space availability.

Parametric Equivalent (HS25 10K F): Matches resistance value (10 kOhms), tolerance (±1%), composition, housing type, and mounting features. Power rating is reduced to 25W. This substitution is applicable only in applications where the 50W power dissipation requirement can be met by a 25W component, or where lower power dissipation is acceptable. Mechanical dimensions are smaller (27.30mm L vs. 49.10mm L).

Parameter Comparison

Engineering Selection Recommendations

850F10KE Selection: This direct equivalent is suitable for applications requiring 50W power dissipation with 10 kOhms resistance and ±1% tolerance. The 5ppm/°C difference in temperature coefficient (±20ppm/°C) provides improved thermal stability compared to the main part. Verify that the increased width (28.00mm vs. 14.20mm) accommodates available mounting space. Both parts maintain active product status and RoHS compliance.

HS25 10K F Selection: This parametric equivalent applies only to applications where power dissipation requirements are 25W or lower. The reduced physical length (27.30mm) may provide space advantages in compact designs. Maintain identical width (14.20mm) and height (14.80mm) as the main part for mounting compatibility. Both parts are active products with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 850F10KE replace the HS50 10K F in all applications? A: The 850F10KE matches the 50W power rating and electrical specifications (10 kOhms ±1%). The primary consideration is mechanical fit: the 850F10KE width is 28.00mm compared to 14.20mm for the HS50 10K F. Confirm available mounting space before substitution.

Q: When is the HS25 10K F an acceptable substitute? A: The HS25 10K F is applicable only when circuit power dissipation requirements are 25W or lower. If the design requires 50W dissipation capability, this part is not suitable. Verify actual power dissipation in the application before selecting this option.

Q: What is the significance of the temperature coefficient difference between HS50 10K F and 850F10KE? A: The HS50 10K F has ±25ppm/°C while the 850F10KE has ±20ppm/°C. This 5ppm/°C difference indicates the 850F10KE exhibits slightly better resistance stability across temperature variations. For precision applications with tight tolerance requirements, this may be advantageous.

Q: Are all substitute parts RoHS compliant? A: Yes. The HS50 10K F is ROHS3 compliant, the 850F10KE is RoHS compliant, and the HS25 10K F is ROHS3 compliant. All parts meet environmental compliance standards.

Q: What are the key parameters that determine substitution eligibility? A: Substitution eligibility is determined by: resistance value (10 kOhms), tolerance (±1%), power rating (50W for direct equivalents, 25W or lower for parametric equivalents), composition (wirewound), housing type (aluminum), mounting features (flanges), and lead style (solder lugs). Mechanical dimensions must be verified for physical fit in the application.
