HS25 10R F Equivalent & Substitute Parts

Part Overview

The HS25 10R F is a 10 Ohms ±1% 25W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for applications requiring precision resistance with high power dissipation capability in a compact aluminum-housed form factor. The part maintains Active product status with 981 units in current inventory. Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and application-specific performance requirements where parametric compatibility is maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS25 10R F is determined by strict parametric alignment across electrical and mechanical specifications. The following criteria establish valid equivalency:

Primary Electrical Parameters: Resistance value (10 Ohms), tolerance (±1%), and power rating (25W) must match exactly. Composition must remain wirewound to preserve thermal and frequency response characteristics.

Mechanical Compatibility: Housing type (aluminum), mounting feature (flanges), lead style (solder lugs), and package configuration (axial, box) must be identical to ensure direct physical and electrical substitution without circuit board redesign.

Secondary Considerations: Temperature coefficient, RoHS compliance status, and MSL rating are evaluated for application-specific requirements but do not disqualify substitution when primary parameters align.

The identified substitute parts meet these criteria and are classified as direct manufacturer equivalents within the ARCOL product family.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and meet RoHS compliance requirements, confirming suitability for current design implementations. Selection between HS25 10R F (Ohmite), 825F10RE (ARCOL), and HS25 10R F (ARCOL) is based on parametric equivalency and inventory availability.

The 825F10RE (ARCOL Metal-Mite®89 series) exhibits a superior temperature coefficient of ±20ppm/°C compared to ±100ppm/°C for both HS25 10R F variants, providing enhanced stability across temperature extremes. This characteristic is relevant for precision applications where thermal drift must be minimized.

The HS25 10R F (ARCOL) variant includes documented pulse withstanding capability, an additional feature not specified for the Ohmite equivalent, offering enhanced transient performance in switching or impulse-driven circuits.

All three parts are mechanically and electrically interchangeable within the specified parameters. Selection should prioritize inventory availability, delivery lead time, and application-specific performance requirements regarding temperature stability or pulse handling.

Frequently Asked Questions (FAQ)

Q: Can 825F10RE directly replace HS25 10R F in existing designs?

A: Yes. Both parts share identical resistance (10 Ohms), tolerance (±1%), power rating (25W), composition (wirewound), housing (aluminum), mounting (flanges), lead style (solder lugs), and package configuration (axial, box). No circuit board modifications are required. The 825F10RE offers improved temperature coefficient performance (±20ppm/°C vs. ±100ppm/°C).

Q: What is the difference between the two HS25 10R F part numbers?

A: Both HS25 10R F designations are electrically and mechanically identical. The Ohmite version carries ROHS3 Compliant certification, while the ARCOL version carries standard RoHS Compliant status and includes documented pulse withstanding capability. Both are parametrically equivalent for direct substitution.

Q: Are there dimensional differences between substitute parts?

A: The Ohmite HS25 10R F measures 1.075" L x 0.559" W (27.30mm x 14.20mm). Both ARCOL variants (825F10RE and HS25 10R F) measure 1.075" L x 1.102" W (27.30mm x 28.00mm). Height-seated maximum is 0.583" (14.80mm) for all three parts. Verify board layout clearance for the wider ARCOL variants before substitution.

Q: Which part offers the best temperature stability?

A: The 825F10RE (ARCOL Metal-Mite®89) provides the lowest temperature coefficient at ±20ppm/°C, compared to ±100ppm/°C for both HS25 10R F variants. Select 825F10RE for applications requiring minimal thermal drift.

Q: Are all parts RoHS compliant?

A: Yes. The Ohmite HS25 10R F is ROHS3 Compliant. Both ARCOL variants (825F10RE and HS25 10R F) are RoHS Compliant. All three parts meet current environmental compliance standards.
