HS15 15R F Equivalent & Substitute Parts

Part Overview

The HS15 15R F is a 15-ohm, 15-watt wirewound chassis mount resistor manufactured by Ohmite. This component is designed for applications requiring precision resistance with pulse withstanding capability in a compact aluminum-housed form factor. The part is currently in active production status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS15 15R F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 15 Ohms (exact match required)
• Tolerance: ±1% (precision class match)
• Composition: Wirewound (construction type match)

Mechanical Compatibility Requirements:

• Housing type: Aluminum (thermal and structural properties)
• Mounting feature: Flanges (board integration compatibility)
• Lead style: Solder Lugs (connection interface)
• Physical dimensions: 0.783" L x 0.827" W x 11.00mm H maximum (form factor fit)

Regulatory Compliance Requirements:

• RoHS Compliant status (environmental standard)
• Moisture Sensitivity Level 1 (unlimited exposure tolerance)

Power Rating Consideration: The HS15 15R F operates at 15W. Substitute parts must maintain the same resistance and tolerance specifications. Power rating differences are noted but do not disqualify substitution when all other parameters align, as the electrical load requirements of the application determine actual power dissipation.

Engineering Selection Recommendations

HS15 15R F (Ohmite) - Primary Selection

The HS15 15R F maintains active product status with full RoHS compliance and unlimited moisture sensitivity rating. This part is suitable for applications requiring the specified 15W power dissipation capacity with 100ppm/°C temperature coefficient performance.

810F15RE (ARCOL) - Substitute Selection

The 810F15RE is an active-status substitute that matches all critical mechanical and electrical parameters: 15-ohm resistance, ±1% tolerance, wirewound construction, aluminum housing, flanged mounting, and solder lug termination. Physical dimensions are identical. RoHS compliance and MSL 1 rating are maintained.

The 810F15RE operates at 10W power rating versus the 15W rating of the HS15 15R F. The temperature coefficient specification differs (±20ppm/°C versus 100ppm/°C). These differences must be evaluated against application thermal and stability requirements. Selection between these parts depends on whether the application's actual power dissipation and temperature stability requirements align with the 810F15RE's specifications.

Frequently Asked Questions (FAQ)

Q: Can the 810F15RE replace the HS15 15R F in all applications?

A: The 810F15RE matches all mechanical and core electrical parameters (resistance, tolerance, composition, housing, mounting, dimensions). However, the 10W power rating is lower than the HS15 15R F's 15W rating. Substitution is valid only if the application's actual power dissipation does not exceed 10W. Additionally, the temperature coefficient differs; verify that the ±20ppm/°C specification of the 810F15RE meets application stability requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the HS15 15R F and 810F15RE share identical dimensions: 0.783" length, 0.827" width, and 0.433" maximum seated height. Both use flanged mounting with solder lug termination, ensuring mechanical interchangeability in the PCB layout.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the HS15 15R F and 810F15RE are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What is the significance of the temperature coefficient difference?

A: The HS15 15R F specifies 100ppm/°C while the 810F15RE specifies ±20ppm/°C. Temperature coefficient indicates how much the resistance value changes with temperature. Applications requiring tight resistance stability across temperature ranges should verify that the 810F15RE's ±20ppm/°C specification is acceptable for the operating environment.

Q: Why is the power rating different between these parts?

A: Power rating reflects the component's thermal dissipation capacity. The HS15 15R F is rated for 15W while the 810F15RE is rated for 10W. The actual power dissipated in an application depends on the circuit current and the 15-ohm resistance value. Substitution requires confirmation that circuit conditions do not exceed 10W dissipation.
