Key Parameters

Substitute Part Grouping Explanation

The 825F150E qualifies as a direct substitute for the HS25 150R F based on the following critical parameters:

• Resistance Value: Both parts are rated at 150 ohms
• Tolerance: Both maintain ±1% tolerance
• Power Rating: Both are rated for 25W dissipation
• Composition: Both are wirewound construction
• Mounting Configuration: Both feature flanged chassis mount design with solder lugs
• Housing Material: Both use aluminum construction
• Package Format: Both are supplied in axial, box configuration
• Compliance: Both are RoHS compliant

The 825F150E is manufactured by Ohmite under the Metal-Mite®89 series and represents an equivalent alternative where the primary electrical and mechanical specifications align with the HS25 150R F.

Parameter Comparison

Engineering Selection Recommendations

Both the HS25 150R F and 825F150E are active production components from Ohmite with full RoHS compliance. The 825F150E offers a defined operating temperature range of -55°C to 275°C and improved temperature coefficient stability at ±20ppm/°C compared to the HS25 150R F specification of 100ppm/°C. Dimensional differences are minimal, with the 825F150E being slightly more compact. Selection between these parts should be based on specific application requirements regarding temperature stability, operating environment, and packaging format (box versus tray).

Frequently Asked Questions (FAQ)

Q: Can the 825F150E be used as a direct replacement for the HS25 150R F?

A: Yes. Both parts share identical electrical specifications (150 ohms, ±1%, 25W) and equivalent mechanical mounting configurations (flanged chassis mount with solder lugs). Dimensional variations are within typical tolerance ranges for this component category.

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

A: The primary differences are temperature coefficient performance (±20ppm/°C for 825F150E versus 100ppm/°C for HS25 150R F), defined operating temperature range for the 825F150E (-55°C to 275°C), and packaging format (tray versus box). Physical dimensions are similar with minor variations.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant. The 825F150E carries ROHS3 compliance designation and REACH Unaffected status, providing additional regulatory documentation.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (box or tray) does not affect electrical or mechanical performance. Selection should be based on assembly process requirements and inventory management practices.

Q: What should be considered when selecting between these substitutes?

A: Consider application temperature range requirements, temperature coefficient stability needs, and packaging compatibility with assembly equipment. Both parts are electrically and mechanically equivalent for standard 25-watt, 150-ohm chassis mount applications.
