Substitute Part Grouping Explanation

The 825FR10E qualifies as a direct substitute for the HS25 R1 F based on the following critical parameters:

Electrical equivalence is established through matching resistance value (100 mOhms), tolerance (±1%), and power rating (25W). Both components utilize wirewound construction with aluminum housing and solder lug termination, satisfying mechanical compatibility requirements. Temperature coefficient variance (±90 ppm/°C for 825FR10E versus ±100 ppm/°C for HS25 R1 F) remains within acceptable substitution limits for this resistor category. Both parts maintain ROHS3 compliance and identical HTSUS classification (8533.29.0000), confirming regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both HS25 R1 F and 825FR10E maintain Active product status with current manufacturing support. Selection between these components should be based on packaging requirements and inventory availability. The HS25 R1 F is supplied in Bulk packaging with 763 units in stock, while the 825FR10E is supplied in Tray packaging with 768 units available. Both components satisfy ROHS3 compliance and REACH unaffected status, confirming suitability for regulated applications. The 825FR10E operates across a defined temperature range (-55°C to 275°C), providing explicit thermal operating boundaries for system design verification.

Frequently Asked Questions (FAQ)

Q: Can the 825FR10E replace the HS25 R1 F in existing designs?

A: Yes. Both components share identical electrical specifications (100 mOhms ±1% at 25W) and mechanical compatibility (aluminum housing, flanged mounting, solder lug termination). The temperature coefficient difference (±90 ppm/°C versus ±100 ppm/°C) is within acceptable substitution parameters for this resistor category.

Q: What is the primary difference between these two parts?

A: The components differ in series designation (ARCOL HS versus Metal-Mite®89), packaging format (Bulk versus Tray), and specified operating temperature range. The 825FR10E provides explicit thermal operating limits (-55°C to 275°C), while the HS25 R1 F does not specify operating temperature in the provided data.

Q: Are there packaging considerations for substitution?

A: Yes. The HS25 R1 F is supplied in Bulk packaging, while the 825FR10E is supplied in Tray packaging. Procurement and handling procedures may differ based on packaging format. Verify compatibility with receiving and storage procedures before substitution.

Q: Do both parts meet regulatory requirements?

A: Both components are ROHS3 compliant and REACH unaffected, satisfying current regulatory standards for electronic component applications.
