HS50 220R F Equivalent & Substitute Parts

Part Overview

The HS50 220R F is a 50-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 220 ohms with ±1% tolerance. This component is designed for applications requiring high power dissipation with stable resistance values and pulse withstanding capability. The part maintains active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts become necessary when design constraints require reduced power ratings, alternative packaging configurations, or inventory availability from different manufacturers while maintaining core electrical specifications.

Substitute Part Grouping Explanation

The HS25 220R F from ARCOL qualifies as a parametric equivalent based on the following matching criteria:

Matching electrical specifications: 220 ohms resistance, ±1% tolerance, wirewound composition, and 100ppm/°C temperature coefficient ensure identical electrical performance in circuits designed for the nominal resistance value.

Matching mechanical specifications: Aluminum housing, flanged mounting feature, and solder lug lead style provide compatible physical integration into existing designs.

Matching compliance and environmental ratings: RoHS compliance and MSL 1 (Unlimited) rating maintain regulatory and reliability standards.

Primary difference: The HS25 220R F operates at 25W power rating, making it suitable for applications where the full 50W capacity of the HS50 220R F is not required. This substitution is valid only when circuit power dissipation requirements do not exceed 25 watts.

Engineering Selection Recommendations

Both the HS50 220R F and HS25 220R F maintain active product status with full RoHS compliance and identical MSL ratings, ensuring long-term availability and regulatory consistency. Selection between these parts depends solely on power dissipation requirements within the circuit. The HS50 220R F is specified for applications requiring the full 50-watt capacity. The HS25 220R F is suitable for circuits where power dissipation does not exceed 25 watts, offering a more compact form factor with reduced length while maintaining identical width and height dimensions. Both parts carry equivalent certifications and environmental ratings, making either choice valid from a compliance perspective when power requirements are met.

Frequently Asked Questions (FAQ)

Q: Can the HS25 220R F replace the HS50 220R F in any application?

A: The HS25 220R F is electrically and mechanically compatible only when circuit power dissipation does not exceed 25 watts. If the design requires 50-watt capacity, the HS25 220R F is not suitable.

Q: What are the key differences between these two parts?

A: The primary difference is power rating: 50W versus 25W. The HS25 220R F is also more compact in length (1.075" versus 1.933"). All other electrical and mechanical specifications, including resistance, tolerance, composition, housing type, and compliance ratings, are identical.

Q: Are there any compliance or environmental differences?

A: No. Both parts are RoHS compliant with MSL 1 (Unlimited) rating and active product status, ensuring equivalent regulatory and environmental performance.

Q: Does the smaller physical size of the HS25 220R F affect performance?

A: The reduced length of the HS25 220R F is a direct result of its lower power rating. The width and height dimensions remain identical. Physical size does not affect electrical performance when power requirements are met.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability is valid only when the HS25 220R F power rating meets circuit requirements. The identical width and height dimensions allow direct mechanical substitution in most layouts, but power dissipation must be verified before implementation.
