Substitute Part Grouping Explanation

Substitution for the HS10 75R J is determined by maintaining equivalence across the following critical parameters:

• Resistance value: 75 Ohms (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• RoHS compliance: Required for regulatory compatibility

Tolerance and temperature coefficient variations within industry-standard ranges are permissible when the substitute part maintains the same functional performance envelope. Physical dimensions must remain compatible with the flanged mounting interface.

Parameter Comparison

Engineering Selection Recommendations

Both the HS10 75R J and HS10 75R F are active production components with RoHS compliance certification, suitable for applications requiring regulatory adherence. The HS10 75R F offers improved tolerance specification (±1% versus ±5%), which may provide enhanced precision in circuits with tighter resistance value requirements. Both components maintain identical power ratings, composition, housing type, and mounting interfaces. The dimensional difference in width (0.650" versus 0.335") must be evaluated against available board space in the target application. Selection between these parts should be based on tolerance requirements and physical layout constraints specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the HS10 75R F replace the HS10 75R J in all applications?

A: The HS10 75R F is electrically and mechanically compatible as a substitute. The primary differences are improved tolerance (±1% versus ±5%) and reduced width dimension. Verify that the narrower width accommodates your board layout and that the tighter tolerance does not introduce cost considerations for your application.

Q: What is the significance of the tolerance difference between these parts?

A: The HS10 75R J has ±5% tolerance, while the HS10 75R F has ±1% tolerance. For applications requiring precise resistance values, the HS10 75R F provides better accuracy. For general-purpose applications, both tolerances are functionally equivalent.

Q: Are the physical dimensions interchangeable?

A: Both parts share identical length (0.626") and height (0.346"), but differ in width (0.650" versus 0.335"). The flanged mounting interface is compatible, but board layout space must accommodate the width difference. Verify clearance in your specific PCB design.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the HS10 75R J and HS10 75R F are RoHS compliant and carry identical ECCN and HTSUS classifications, ensuring equivalent regulatory status for procurement and deployment.

Q: What is the temperature coefficient specification used for?

A: Temperature coefficient indicates resistance value drift with temperature changes. The HS10 75R J specifies 100ppm/°C, while the HS10 75R F specifies ±100ppm/°C. Both values are within standard wirewound resistor performance ranges and are suitable for typical industrial operating conditions.
