Substitute Part Grouping Explanation

The HS10 68R F qualifies as a parametric equivalent to the HS10 68R J based on the following criteria:

Matching Parameters:

• Resistance value: 68 Ohms (identical)
• Power rating: 10W (identical)
• Composition: Wirewound (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Housing type: Aluminum (identical)
• Mounting feature: Flanges (identical)
• Lead style: Solder Lugs (identical)
• Package type: Axial, Box (identical)
• Physical dimensions: 0.626" L x 0.335" W, 0.346" H seated (identical)
• Compliance: ROHS3 Compliant, REACH Unaffected (identical)

Differentiating Parameter:

• Tolerance: HS10 68R J specifies ±5%, while HS10 68R F specifies ±1%

The HS10 68R F represents a tighter tolerance variant of the same base design. This substitution is valid in applications where improved tolerance performance is acceptable or required.

Parameter Comparison

Engineering Selection Recommendations

Both the HS10 68R J and HS10 68R F are active production components with ROHS3 compliance and REACH unaffected status, suitable for regulated applications. Selection between these parts depends on tolerance requirements:

• HS10 68R J (±5% tolerance): Select when circuit design accommodates standard tolerance specifications and cost optimization is prioritized.
• HS10 68R F (±1% tolerance): Select when circuit design requires tighter resistance tolerance control or when higher precision is specified in design documentation.

Both parts share identical mechanical mounting, thermal characteristics, and power dissipation capabilities, ensuring direct substitution at the board level when tolerance requirements are met.

Frequently Asked Questions (FAQ)

Q: Can HS10 68R F replace HS10 68R J in existing designs?

A: Yes. The HS10 68R F is mechanically and electrically compatible with identical mounting, power rating, and thermal characteristics. The primary difference is tolerance specification (±1% versus ±5%). Substitution is valid provided the circuit design accepts the tighter tolerance of the HS10 68R F.

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

A: The HS10 68R J carries ±5% tolerance while the HS10 68R F carries ±1% tolerance. All other electrical and mechanical parameters are identical, including 68 Ohms resistance, 10W power rating, wirewound composition, and aluminum flanged housing.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.626" L x 0.335" W with a seated height of 0.346". They use identical solder lug termination and flanged mounting features, ensuring direct board-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both HS10 68R J and HS10 68R F are ROHS3 compliant and REACH unaffected, suitable for applications requiring regulatory compliance.

Q: Which part should be selected for precision applications?

A: The HS10 68R F with ±1% tolerance is appropriate for applications requiring tighter resistance accuracy. Selection should be based on circuit design specifications and tolerance requirements documented in the design schematic.
