Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS50 R10 F are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Resistance value: 100 mOhms
• Tolerance: ±1%
• Power rating: 50W
• Composition: Wirewound

Mechanical Compatibility Criteria:

• Housing type: Aluminum
• Mounting feature: Flanges
• Lead style: Solder Lugs
• Package type: Axial, Box

Compliance Criteria:

• RoHS3 Compliant status
• REACH Unaffected status

Two substitute parts meet these criteria: the 850FR10E (direct manufacturer equivalent with different series designation) and the HS50 R1 F (parametric equivalent within the same ARCOL HS series).

Parameter Comparison

Engineering Selection Recommendations

All three parts—HS50 R10 F, 850FR10E, and HS50 R1 F—maintain Active product status and ROHS3 compliance with REACH Unaffected designation, confirming regulatory alignment for current applications.

The HS50 R1 F provides parametric equivalence within the same ARCOL HS series, maintaining identical resistance, tolerance, power rating, temperature coefficient, and physical dimensions as the primary part HS50 R10 F. This option is suitable for direct substitution where series continuity is preferred.

The 850FR10E offers direct manufacturer equivalence with marginally improved temperature coefficient performance (±90ppm/°C versus ±100ppm/°C). Physical dimensions differ slightly: the 850FR10E measures 1.938" L x 1.156" W with 0.620" seated height, compared to the HS50 R10 F at 1.933" L x 0.559" W with 0.583" seated height. This dimensional variance requires mechanical layout verification before selection. The 850FR10E operates across -55°C to 275°C, whereas operating temperature limits are not specified for the HS50 R10 F.

Frequently Asked Questions (FAQ)

Q: Can the 850FR10E replace the HS50 R10 F in all applications?

A: The 850FR10E matches all critical electrical parameters and maintains equivalent RoHS and REACH compliance. However, physical dimensions differ. The 850FR10E is wider (1.156" versus 0.559") and taller (0.620" versus 0.583"), requiring verification that the circuit board layout and mechanical mounting accommodate these differences.

Q: What is the difference between the HS50 R1 F and HS50 R10 F?

A: Both parts are identical in all provided electrical and mechanical specifications, including resistance, tolerance, power rating, temperature coefficient, dimensions, and compliance status. The designation difference reflects packaging or inventory tracking within the ARCOL HS series. Both are suitable for direct substitution.

Q: Does the temperature coefficient difference between HS50 R10 F and 850FR10E affect circuit performance?

A: The temperature coefficient difference is ±100ppm/°C versus ±90ppm/°C. This 10ppm/°C variance is minor and affects only high-precision applications operating across wide temperature ranges. For standard power dissipation circuits, this difference is negligible.

Q: Are all substitute parts available in the same packaging?

A: The HS50 R10 F and HS50 R1 F are available in Bulk packaging. The 850FR10E is also available in Bulk packaging. All three parts use identical Axial, Box package types with solder lug leads.

Q: What compliance certifications apply to these parts?

A: All three parts—HS50 R10 F, 850FR10E, and HS50 R1 F—are ROHS3 Compliant and REACH Unaffected, confirming regulatory compliance for current industrial and commercial applications.
