Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS10 75R J is determined by the following critical parameters:

• Resistance Value: Must be 75 Ohms
• Power Rating: Must be 10W minimum
• Composition: Must be Wirewound
• Temperature Coefficient: Must be ±100ppm/°C or better
• Housing Type: Must be Aluminum
• Mounting Feature: Must include Flanges
• Lead Style: Must be Solder Lugs
• Package Type: Must be Axial, Box
• Physical Dimensions: Must match 0.626" L x 0.335" W and 0.346" height seated maximum
• Tolerance: May be equal to or tighter than ±5%

The HS10 75R F qualifies as a parametric equivalent because it maintains all critical electrical and mechanical specifications while offering improved tolerance performance (±1% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

Both the HS10 75R J and HS10 75R F are active production components with RoHS compliance. The HS10 75R F offers tighter tolerance specification (±1% versus ±5%) while maintaining identical electrical and mechanical characteristics. Selection between these parts should be based on application tolerance requirements and inventory availability. The HS10 75R F provides enhanced precision for applications requiring stricter resistance value control.

Frequently Asked Questions (FAQ)

Q: Can HS10 75R F replace HS10 75R J in existing designs?

A: Yes. The HS10 75R F maintains identical resistance value, power rating, composition, temperature coefficient, housing type, mounting features, lead style, package type, and physical dimensions. The tighter tolerance of ±1% is a performance enhancement compatible with applications designed for ±5% tolerance.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.626" L x 0.335" W (15.90mm x 8.50mm) with a maximum seated height of 0.346" (8.80mm), ensuring direct mechanical compatibility in existing PCB layouts and chassis mount applications.

Q: What is the difference between ROHS3 and RoHS compliance?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current EU RoHS Directive 2011/65/EU as amended. Both parts meet hazardous substance restrictions applicable to electronic components.

Q: Are these parts suitable for high-frequency applications?

A: These are wirewound resistors with a temperature coefficient of ±100ppm/°C. Frequency response characteristics are not specified in the provided parameters and should be evaluated based on specific application requirements.

Q: What mounting configurations are supported?

A: Both parts feature flanged mounting with solder lug termination, suitable for chassis mount applications with direct solder connection to PCBs or terminal strips.
