HS25 5K F Equivalent & Substitute Parts

Part Overview

The HS25 5K F is a 25-watt wirewound chassis mount resistor manufactured by Ohmite, featuring 5 kOhms resistance with ±1% tolerance. This component is designed for applications requiring high power dissipation in a compact aluminum-housed form factor with flanged mounting. The part is currently in active production status with 882 units in stock. Substitute parts are identified when they maintain identical electrical specifications (resistance value, tolerance, power rating, composition) and compatible mechanical characteristics (housing type, mounting features, lead style) while potentially offering different packaging or minor dimensional variations.

Substitute Part Grouping Explanation

The HS25 5K F can be substituted with the 825F5K0E based on the following matching criteria:

Electrical Equivalence:

• Identical resistance value: 5 kOhms
• Identical tolerance: ±1%
• Identical power rating: 25W
• Identical composition: Wirewound

Mechanical Compatibility:

• Identical housing type: Aluminum
• Identical mounting feature: Flanges
• Identical lead style: Solder Lugs
• Identical package classification: Axial, Box

Regulatory Compliance:

• Both parts are RoHS compliant
• Both parts have MSL rating of 1 (Unlimited)
• Both parts classified under ECCN EAR99 and HTSUS 8533.29.0000

The 825F5K0E belongs to Ohmite's Metal-Mite®89 series and represents a direct functional equivalent with minor dimensional and packaging variations.

Parameter Comparison

Engineering Selection Recommendations

Both the HS25 5K F and 825F5K0E are active production components from Ohmite with full RoHS compliance. The 825F5K0E offers ROHS3 compliance, representing a more recent regulatory certification level. Selection between these parts should be based on:

Availability and Packaging: The 825F5K0E is currently available in higher quantity (1058 units) and ships in tray packaging, which may provide cost advantages for high-volume applications. The HS25 5K F is supplied in box packaging.

Dimensional Fit: The 825F5K0E has slightly smaller overall dimensions (approximately 0.013" shorter in length, 0.008" narrower in width, and 0.027" lower in height). Verify that the reduced height clearance of 0.556" maximum does not conflict with existing PCB layout or enclosure constraints.

Temperature Coefficient: The HS25 5K F specifies 25ppm/°C while the 825F5K0E specifies ±20ppm/°C. For applications with strict temperature stability requirements, confirm that the ±20ppm/°C specification of the substitute meets circuit performance criteria.

Operating Temperature: The 825F5K0E provides explicit operating temperature range (-55°C ~ 275°C), while the HS25 5K F does not specify this parameter in available documentation. If operation outside standard industrial temperature ranges is required, the 825F5K0E's documented range provides design assurance.

Frequently Asked Questions (FAQ)

Q: Can the 825F5K0E be used as a direct replacement for the HS25 5K F in existing designs?

A: Yes, the 825F5K0E is electrically and mechanically equivalent. Both parts share identical resistance (5 kOhms), tolerance (±1%), power rating (25W), composition (wirewound), housing type (aluminum), mounting features (flanges), and lead style (solder lugs). Verify that the slightly smaller dimensions of the 825F5K0E do not create clearance issues in your specific PCB layout or enclosure.

Q: What are the key differences between these two parts?

A: The primary differences are packaging format (box versus tray), inventory availability, dimensional tolerances (the 825F5K0E is approximately 0.027" shorter in height), temperature coefficient specification (25ppm/°C versus ±20ppm/°C), and RoHS certification level (RoHS Compliant versus ROHS3 Compliant). Electrical performance and power handling are identical.

Q: Are there any temperature-related limitations when substituting?

A: The 825F5K0E explicitly specifies an operating temperature range of -55°C to 275°C. The HS25 5K F does not provide this specification in available data. If your application operates at temperature extremes, the 825F5K0E's documented range provides design confidence. For standard industrial applications (-40°C to +85°C), both parts are suitable.

Q: Does the temperature coefficient difference affect circuit performance?

A: The HS25 5K F specifies 25ppm/°C while the 825F5K0E specifies ±20ppm/°C. For most applications, this difference is negligible. However, in precision analog circuits or applications with tight tolerance requirements across temperature ranges, calculate the maximum resistance drift to confirm acceptability. At a 50°C temperature change, the HS25 5K F would drift approximately 0.125%, while the 825F5K0E would drift up to ±0.1%.

Q: Which part should I select for new designs?

A: For new designs, either part is acceptable based on electrical equivalence. Consider the 825F5K0E if higher inventory availability, tray packaging for automated assembly, or ROHS3 compliance certification is preferred. Verify dimensional fit within your specific enclosure or PCB layout constraints.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are manufactured by Ohmite and carry appropriate RoHS compliance certifications. Both have MSL rating 1 (Unlimited moisture sensitivity), indicating suitability for standard storage and handling. Confirm specific reliability requirements (such as MIL-grade specifications or failure rate data) with your application requirements, as this information is not provided in the standard datasheets.
