HS25 R5 F Equivalent & Substitute Parts

Part Overview

The HS25 R5 F is a 500 mOhms ±1% 25W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for applications requiring precision current sensing, power dissipation, and mechanical stability in chassis-mounted configurations. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

The 825FR50E qualifies as a direct substitute for the HS25 R5 F based on the following critical parameters:

• Identical resistance value: 500 mOhms
• Matching tolerance: ±1%
• Equivalent power rating: 25W
• Same composition: Wirewound
• Identical housing material: Aluminum
• Matching mounting feature: Flanges
• Same lead style: Solder Lugs
• Equivalent package classification: Axial, Box
• Matching compliance: ROHS3 Compliant, REACH Unaffected

The substitute part operates within the allowed parameter variance for this product category. Temperature coefficient differs slightly (±90ppm/°C vs ±100ppm/°C), and physical dimensions vary within acceptable mechanical tolerances for flanged chassis mount applications. Operating temperature range is specified for the substitute part (-55°C ~ 275°C), providing extended thermal operating capability.

Parameter Comparison

Engineering Selection Recommendations

Both the HS25 R5 F and 825FR50E maintain Active product status with full regulatory compliance. Selection between these parts should be based on:

• Packaging format requirements: HS25 R5 F is supplied in Bulk packaging; 825FR50E is supplied in Tray packaging
• Inventory availability: HS25 R5 F has 975 units in stock; 825FR50E has 649 units in stock
• Series designation: HS25 R5 F belongs to ARCOL HS series; 825FR50E belongs to Metal-Mite®89 series
• Physical dimensions: HS25 R5 F measures 1.075" L x 0.559" W; 825FR50E measures 1.062" L x 1.094" W

Both parts satisfy ROHS3 compliance and REACH unaffected requirements for regulated applications. The 825FR50E provides specified operating temperature range (-55°C ~ 275°C), which may be advantageous for extended thermal applications.

Frequently Asked Questions (FAQ)

Q: Can the 825FR50E directly replace the HS25 R5 F in existing designs?

A: Yes. Both parts share identical electrical specifications (500 mOhms, ±1%, 25W) and mechanical mounting features (flanged aluminum chassis mount with solder lugs). Physical dimensions differ slightly but remain compatible with standard flanged mounting configurations.

Q: What is the significance of the temperature coefficient difference?

A: The HS25 R5 F specifies ±100ppm/°C while the 825FR50E specifies ±90ppm/°C. The 825FR50E exhibits lower temperature coefficient, indicating superior resistance stability across temperature variations. This represents an improvement over the main part specification.

Q: Are there packaging considerations for substitution?

A: Yes. The HS25 R5 F is supplied in Bulk packaging, while the 825FR50E is supplied in Tray packaging. Bulk packaging typically accommodates larger quantities in loose form, while Tray packaging provides organized component arrangement. Selection depends on assembly process requirements and handling procedures.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the HS25 R5 F and 825FR50E are ROHS3 Compliant and REACH Unaffected, meeting identical environmental and hazardous substance restrictions.

Q: What are the physical dimension differences?

A: HS25 R5 F: 1.075" L x 0.559" W x 0.583" H (27.30mm x 14.20mm x 14.80mm). 825FR50E: 1.062" L x 1.094" W x 0.556" H (26.98mm x 27.79mm x 14.12mm). The 825FR50E is wider but slightly shorter. Both fit standard flanged chassis mount footprints.

Q: Which part should be selected for new designs?

A: Both parts are Active and suitable for new designs. Selection should be based on packaging format preference, inventory availability, and physical space constraints within the application. The 825FR50E offers extended operating temperature specification and improved temperature coefficient performance.
