Key Parameters

Substitute Part Grouping Explanation

Substitution for the HS100 8R F is determined by strict equivalence across the following critical parameters:

• Resistance value: 8 Ohms
• Tolerance specification: ±1%
• Power dissipation capability: 100W
• Composition type: Wirewound
• Temperature coefficient: ±100ppm/°C
• Housing material: Aluminum
• Mounting configuration: Flanges with solder lugs
• Physical dimensions: 2.566" L x 1.075" W (65.20mm x 27.30mm), height 0.949" (24.10mm)
• Compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The HS100 8R F maintains Active product status with full ROHS3 compliance and REACH unaffected classification, confirming suitability for current production applications. Selection of equivalent parts should be based on verification that all parameters listed in the Key Parameters table match exactly. The aluminum housing with flanged mounting provides thermal management suitable for 100W continuous dissipation. Solder lug termination requires appropriate PCB or chassis mounting infrastructure. Inventory availability of 708 units supports immediate procurement without lead time constraints.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the HS100 8R F? A: A valid substitute must match all electrical parameters (8 Ohms ±1%, 100W, ±100ppm/°C), composition (wirewound), housing material (aluminum), mounting configuration (flanges with solder lugs), and physical dimensions (2.566" L x 1.075" W x 0.949" H). Compliance certifications must include ROHS3 and REACH unaffected status.

Q: Can lower tolerance resistors substitute for the HS100 8R F? A: No. The ±1% tolerance is a specified parameter. Substitutes must maintain this tolerance specification. Tighter tolerances may be acceptable only if explicitly verified against circuit requirements, but this represents a design change rather than a direct substitution.

Q: Are there dimensional constraints for mounting? A: Yes. The flanged mounting configuration with specified dimensions (2.566" L x 1.075" W x 0.949" H) is a mechanical requirement. Substitute parts must match these dimensions to ensure proper chassis mounting and thermal contact.

Q: What is the significance of the ±100ppm/°C temperature coefficient? A: This parameter defines the resistor's stability across temperature variations. Substitutes must maintain this specification to preserve circuit performance across the operating temperature range.

Q: Does ROHS3 compliance affect substitution eligibility? A: Yes. ROHS3 compliance is a mandatory certification for this part. All substitutes must maintain equivalent compliance status for regulatory and procurement purposes.
