HS300 16R F Equivalent & Substitute Parts

Part Overview

The HS300 16R F is a 300-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 16 ohms with ±1% tolerance. This component is designed for high-power applications requiring pulse withstanding capability and thermal stability. The part maintains active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts become necessary when application constraints require lower power dissipation, alternative packaging configurations, or inventory availability considerations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS300 16R F is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 16 Ohms
• Tolerance: ±1%
• Composition: Wirewound
• Temperature Coefficient: 100ppm/°C range

Mechanical Parameters (Must Match):

• Housing Type: Aluminum
• Mounting Feature: Flanges
• Lead Style: M6 Threaded
• Height - Seated (Max): 1.646" (41.80mm)

Compliance Parameters (Must Match):

• RoHS Status: RoHS Compliant
• MSL Rating: 1 (Unlimited)

The HS200 16R F qualifies as a parametric equivalent based on matching all electrical, mechanical, and compliance parameters. The primary distinction is the reduced power rating (200W versus 300W), which represents a functional downgrade suitable only for applications with lower thermal requirements.

Engineering Selection Recommendations

HS300 16R F (Primary Selection): Select the HS300 16R F for applications requiring the full 300-watt power dissipation capability. This part maintains active product status with confirmed RoHS compliance and unlimited moisture sensitivity rating, supporting deployment in industrial and high-reliability environments.

HS200 16R F (Substitute Selection): The HS200 16R F from ARCOL serves as a substitute only when application thermal requirements do not exceed 200 watts. Both parts share identical electrical specifications (16 ohms, ±1% tolerance), mechanical mounting configuration (M6 threaded flanges, 1.646" seated height), and compliance certifications (RoHS compliant, MSL 1). The HS200 16R F maintains active product status and is available in bulk packaging. Selection of this substitute requires confirmation that the reduced power rating does not compromise circuit performance or thermal management.

Frequently Asked Questions (FAQ)

Q: Can the HS200 16R F replace the HS300 16R F in all applications?

A: No. The HS200 16R F is suitable only for applications where continuous power dissipation does not exceed 200 watts. Applications requiring the full 300-watt capability must use the HS300 16R F. Verify actual power dissipation in your circuit before substitution.

Q: Are the physical dimensions compatible between these parts?

A: The parts share identical height (1.646" maximum seated height) and width (2.854"), with the HS200 16R F having a reduced length (4.631" versus 5.028"). Both use M6 threaded flanges for mounting. Verify mounting clearance in your application before substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the HS300 16R F and HS200 16R F are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity). Both maintain active product status.

Q: What is the difference in temperature coefficient between these parts?

A: The HS300 16R F specifies 100ppm/°C, while the HS200 16R F specifies ±100ppm/°C. Both values fall within the same operational range for temperature stability.

Q: Are there packaging differences between these parts?

A: Yes. The HS300 16R F is supplied in box packaging, while the HS200 16R F is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
