Substitute Part Grouping Explanation

Substitution eligibility for the HS25 2R F is determined by the following critical parameters:

• Resistance value: 2 ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 25W (exact match required)
• Composition: Wirewound (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder lugs (exact match required)
• RoHS compliance: Required for regulatory compatibility

The substitute part 825F2R0E meets all critical electrical and mechanical parameters, enabling direct functional replacement in applications where the HS25 2R F is specified.

Parameter Comparison

Engineering Selection Recommendations

The 825F2R0E is a direct functional equivalent to the HS25 2R F for applications requiring a 2-ohm, 25-watt wirewound chassis mount resistor. Both components are manufactured by Ohmite and maintain identical electrical specifications for resistance, tolerance, and power rating. The 825F2R0E offers enhanced temperature coefficient performance (±50ppm/°C versus 100ppm/°C) and a defined operating temperature range of -55°C to 275°C, providing superior stability in temperature-sensitive applications. Both parts maintain RoHS compliance, with the 825F2R0E meeting ROHS3 standards. Dimensional differences are minimal and functionally equivalent for standard mounting applications. Selection between these parts should be based on packaging requirements (box versus tray) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 825F2R0E replace the HS25 2R F in all applications?

A: Yes, the 825F2R0E meets all critical electrical and mechanical specifications required for direct substitution.
