HS250 15R F Wirewound Chassis Mount Resistor

Part Overview

The HS250 15R F is a 250-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 15 ohms with ±1% tolerance. This component is designed for high-power applications requiring stable resistance performance in industrial and electronic equipment. The part is currently in active production status with RoHS compliance certification. Alternative models may be required due to inventory constraints, application-specific power requirements, or packaging preferences while maintaining equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The HS200 15R F qualifies as a parametric equivalent based on the following matching criteria:

• Resistance value: 15 Ohms (identical)
• Tolerance: ±1% (identical)
• Composition: Wirewound (identical)
• Temperature Coefficient: ±100ppm/°C (equivalent specification)
• Housing Type: Aluminum (identical)
• Mounting Feature: Flanges (identical)
• Lead Style: M6 Threaded (identical)
• RoHS Status: RoHS Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The primary difference is the power rating: HS200 15R F is rated at 200W versus the HS250 15R F at 250W. This substitution is valid for applications where the 200W power rating meets or exceeds the circuit requirement. Physical dimensions differ slightly due to the lower power rating, but mounting compatibility is maintained through identical flange and threaded lead specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the HS250 15R F and HS200 15R F are active production components with RoHS compliance certification. Selection between these parts depends on the application's power dissipation requirements. The HS250 15R F provides 250W capacity and is suitable for high-power applications with maximum thermal stress. The HS200 15R F provides 200W capacity and is suitable for applications where power dissipation does not exceed 200W. Both components maintain identical electrical characteristics (15 ohms, ±1% tolerance) and mechanical compatibility (M6 threaded leads, flange mounting, 1.646" seated height). Component selection should be based on the actual power dissipation in the circuit to ensure reliable long-term operation within the rated power envelope.

Frequently Asked Questions (FAQ)

Q: Can the HS200 15R F replace the HS250 15R F in all applications?

A: The HS200 15R F can replace the HS250 15R F only in applications where the circuit power dissipation does not exceed 200W. If the application requires power handling above 200W, the HS250 15R F must be used to maintain design margin and reliability.

Q: Are the physical dimensions compatible for PCB or chassis mounting?

A: Both components feature identical M6 threaded leads and flange mounting specifications. The seated height is identical at 1.646" (41.80mm). The HS200 15R F has slightly smaller length and width dimensions due to its lower power rating, but mounting compatibility is maintained.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HS250 15R F and HS200 15R F are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry ECCN EAR99 and HTSUS 8533.29.0000 classifications.

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

A: The HS250 15R F specifies 100ppm/°C while the HS200 15R F specifies ±100ppm/°C. Both values represent equivalent temperature stability performance for wirewound chassis mount resistors in this category.

Q: Are there packaging differences between these parts?

A: The HS250 15R F is supplied in box packaging, while the HS200 15R F is supplied in bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical performance.
