Parameter Comparison

Engineering Selection Recommendations

Both the HS25 100R F and 825F100E meet ROHS3 compliance requirements and are classified as REACH unaffected components. Selection between these parts should be based on:

• Packaging Requirements: The HS25 100R F is supplied in bulk packaging, while the 825F100E is supplied in tray format. Choose based on assembly process and handling requirements.
• Temperature Coefficient Performance: The 825F100E exhibits superior temperature stability (±20ppm/°C) compared to the HS25 100R F (±100ppm/°C). Applications requiring tighter thermal drift specifications should prioritize the 825F100E.
• Specified Operating Temperature: The 825F100E provides an explicit operating temperature range of -55°C to 275°C. Applications with defined thermal operating windows should reference this specification.
• Inventory Availability: Both parts maintain active production status with adequate stock levels for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can the 825F100E directly replace the HS25 100R F in existing designs?

A: Yes. Both parts share identical electrical specifications (100 Ohms ±1%, 25W), wirewound construction, aluminum housing, and flanged solder lug termination. The primary difference is packaging format (bulk versus tray) and temperature coefficient performance. Physical dimensions differ slightly; verify mounting clearances in your specific application.

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

A: The HS25 100R F has a temperature coefficient of ±100ppm/°C, while the 825F100E is ±20ppm/°C. This means the 825F100E's resistance value changes less with temperature variations. For precision applications operating across wide temperature ranges, the 825F100E provides superior stability.

Q: Are there packaging considerations when switching between these parts?

A: Yes. The HS25 100R F is supplied in bulk packaging, while the 825F100E uses tray packaging. Bulk packaging is suitable for manual assembly or small-volume production, while tray packaging is optimized for automated pick-and-place assembly. Confirm your assembly process compatibility before substitution.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the HS25 100R F and 825F100E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: What are the physical dimension differences?

A: The HS25 100R F measures 1.075" L × 0.559" W (27.30mm × 14.20mm) with a seated height of 0.583" (14.80mm). The 825F100E measures 1.062" L × 1.094" W (26.98mm × 27.79mm) with a seated height of 0.556" (14.12mm). Verify clearances in your PCB layout and enclosure design before substitution.
