HS300 560R F Equivalent & Substitute Parts

Part Overview

The HS300 560R F is a 560 Ohms ±1% 300W wirewound chassis mount resistor manufactured by Ohmite. This component is designed for high-power applications requiring precision resistance with pulse withstanding capability. The part is currently active in production with 1046 units in stock. Equivalent and substitute parts are identified when identical electrical specifications (resistance value, tolerance, composition) and compatible mechanical interfaces (mounting features, lead style, housing type) are maintained across different power ratings or manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS300 560R F are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 560 Ohms
• Tolerance: ±1%
• Composition: Wirewound
• Temperature Coefficient: 100ppm/°C (±100ppm/°C acceptable)

Mechanical Parameters (Must Match):

• Housing Type: Aluminum
• Mounting Feature: Flanges
• Lead Style: M6 Threaded
• Package / Case: Axial, Box

Variable Parameter (Allowed to Differ):

• Power Rating: May be lower than 300W for applications with reduced thermal requirements

The identified substitutes HS200 560R F and HS250 560R F maintain all critical electrical and mechanical specifications while offering alternative power ratings of 200W and 250W respectively. Both substitute parts are manufactured by ARCOL and carry active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HS300 560R F and its substitutes is determined by application power dissipation requirements:

HS300 560R F (300W): Primary selection for applications requiring full 300W power dissipation capability. Ohmite manufacture. RoHS Compliant status.

HS250 560R F (250W): Suitable for applications with maximum power dissipation up to 250W. ARCOL manufacture. ROHS3 Compliant and REACH Unaffected. Intermediate power rating option.

HS200 560R F (200W): Suitable for applications with maximum power dissipation up to 200W. ARCOL manufacture. ROHS3 Compliant and REACH Unaffected. Lower power rating option.

All three parts maintain identical electrical specifications (560 Ohms ±1%, wirewound composition, 100ppm/°C temperature coefficient) and mechanical compatibility (M6 threaded leads, aluminum housing, flange mounting). Selection is based on thermal design requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can HS200 560R F or HS250 560R F be used in place of HS300 560R F?

A: Substitution is valid only if the application's actual power dissipation does not exceed the substitute part's rating. The HS200 560R F is limited to 200W maximum dissipation, and the HS250 560R F to 250W maximum dissipation. If the circuit requires 300W dissipation, neither substitute is appropriate.

Q: Are the physical dimensions compatible between these parts?

A: All three parts share identical height (1.646" seated maximum) and identical lead style (M6 threaded). Length and width dimensions vary with power rating: HS300 560R F measures 5.028" L x 2.854" W, HS250 560R F measures 4.319" L x 1.791" W, and HS200 560R F measures 4.631" L x 1.791" W. Mechanical mounting compatibility depends on available board space and heat sink design.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. All three parts meet applicable RoHS requirements.

Q: Are these parts interchangeable from a packaging perspective?

A: The HS300 560R F is supplied in Box packaging, while HS200 560R F and HS250 560R F are supplied in Bulk packaging. Electrical and mechanical specifications remain identical; packaging format differs based on supplier inventory management.

Q: What certifications apply to all three parts?

A: All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. ECCN classification is EAR99 for all three parts. HTSUS code 8533.29.0000 applies to all three parts.
