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 specify 150 Ohms
• Tolerance: Both maintain ±1% tolerance
• Power Rating: Both are rated for 25W dissipation
• Composition: Both utilize wirewound construction
• Mounting Configuration: Both feature flange-mounted design with solder lugs
• Housing Material: Both use aluminum construction
• Compliance: Both are ROHS3 compliant

The substitute part is manufactured by the same supplier (Ohmite) and belongs to the Metal-Mite®89 series, confirming electrical and mechanical equivalence for direct circuit replacement.

Parameter Comparison

Engineering Selection Recommendations

Both the HS25 150R F and 825F150E are Active products with ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. Selection between these parts is determined by application-specific requirements:

The 825F150E offers improved temperature coefficient performance (±20ppm/°C versus ±100ppm/°C) and a defined operating temperature range (-55°C ~ 275°C), making it suitable for applications with stringent thermal stability requirements. The HS25 150R F remains the primary specification when the original part number is required for design documentation or when the broader temperature coefficient is acceptable for the application.

Both parts are electrically and mechanically equivalent for 150 Ohm, 25W, ±1% tolerance applications with flange-mounted solder lug configurations.

Frequently Asked Questions (FAQ)

Q: Can the 825F150E replace the HS25 150R F in existing designs?

A: Yes. Both parts share identical resistance (150 Ohms), tolerance (±1%), power rating (25W), composition (wirewound), and mounting configuration (flange-mounted with solder lugs). Mechanical dimensions differ slightly, but both use aluminum housing with identical lead styles.

Q: What is the difference in temperature coefficient between these parts?

A: The HS25 150R F specifies ±100ppm/°C, while the 825F150E specifies ±20ppm/°C. The 825F150E provides superior temperature stability. Applications requiring minimal resistance drift across temperature variations should specify the 825F150E.

Q: Are there packaging differences between these parts?

A: Yes. The HS25 150R F is supplied in Bulk packaging, while the 825F150E is supplied in Tray packaging. Both are suitable for production assembly; packaging selection depends on inventory management and handling requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HS25 150R F and 825F150E are ROHS3 compliant and carry Active product status from Ohmite, confirming equivalent regulatory and support status.

Q: What are the physical dimension differences?

A: The HS25 150R F measures 1.075" L × 0.559" W (27.30mm × 14.20mm) with 0.583" seated height. The 825F150E measures 1.062" L × 1.094" W (26.98mm × 27.79mm) with 0.556" seated height. Both dimensions are within typical chassis mount resistor tolerances and accommodate standard flange-mount footprints.
