HS50 500R F Equivalent & Substitute Parts

Part Overview

The HS50 500R F is a 500 Ohms ±1% 50W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for applications requiring precision resistance with high power dissipation capability in a compact aluminum-housed form factor. The part maintains Active product status with full ROHS3 compliance and is suitable for industrial and electronic equipment applications requiring reliable fixed resistor performance.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS50 500R F are classified based on electrical and mechanical parameter compatibility:

Direct Electrical Equivalent (850F500E): Maintains identical resistance value (500 Ohms), tolerance (±1%), and power rating (50W) with wirewound composition and aluminum housing. This part qualifies as a direct substitute despite differences in temperature coefficient (±20ppm/°C vs. ±100ppm/°C) and operating temperature range (-55°C ~ 275°C vs. unspecified), as these represent performance enhancements rather than limitations. The Metal-Mite®89 series construction provides superior thermal stability.

Parametric Equivalent - Lower Power Rating (HS25 500R F): Shares identical resistance (500 Ohms), tolerance (±1%), composition (wirewound), and housing type (aluminum) with the main part. The 25W power rating represents a reduced capability variant suitable for applications with lower power dissipation requirements. This part is applicable only when circuit design permits operation at the lower 25W specification.

Parametric Equivalent - Same Series (HS50 500R F by ARCOL): Identical electrical specifications (500 Ohms ±1%, 50W) and mechanical construction (aluminum housing, flanges, solder lugs) within the same ARCOL HS series. This represents an alternative source for the same functional specification.

Parameter Comparison

Engineering Selection Recommendations

850F500E (Ohmite Metal-Mite®89): This part provides direct electrical and mechanical substitution with enhanced temperature coefficient performance (±20ppm/°C). Selection is appropriate for applications requiring superior thermal stability and extended operating temperature range (-55°C ~ 275°C). Both parts maintain ROHS3 compliance and equivalent power handling.

HS50 500R F (ARCOL): This part provides identical specifications within the same series family, offering alternative sourcing from ARCOL. Both Ohmite and ARCOL variants maintain RoHS compliance and equivalent electrical performance. Selection between manufacturers is based on procurement availability and supply chain requirements.

HS25 500R F (ARCOL): This part is applicable only when circuit design specifications permit operation at 25W power rating. The reduced power capability limits its use to applications with lower dissipation requirements. Electrical parameters (resistance, tolerance, temperature coefficient) remain equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can the 850F500E directly replace the HS50 500R F in all applications?

A: Yes, the 850F500E provides direct electrical and mechanical substitution. Both parts deliver 500 Ohms ±1% at 50W with aluminum housing and solder lug termination. The 850F500E offers improved temperature coefficient stability (±20ppm/°C vs. ±100ppm/°C) and extended operating temperature range, making it suitable for all applications where the HS50 500R F is specified.

Q: When should the HS25 500R F be used instead of the HS50 500R F?

A: The HS25 500R F is applicable only when circuit design permits operation at 25W power dissipation. This part maintains identical resistance, tolerance, and temperature coefficient specifications but with reduced power handling capability. Use this part only when power requirements are confirmed to be 25W or lower.

Q: Are there mechanical compatibility differences between these substitute parts?

A: All substitute parts feature aluminum housing with flanged mounting and solder lug termination. Physical dimensions vary: the HS50 500R F (Ohmite) measures 1.933" L x 0.559" W, the 850F500E measures 1.938" L x 1.156" W, and the HS25 500R F measures 1.075" L x 0.559" W. Verify mounting space availability before substitution.

Q: What compliance certifications apply to these parts?

A: The HS50 500R F (Ohmite) and 850F500E maintain ROHS3 compliance. The ARCOL variants (HS25 500R F and HS50 500R F) maintain RoHS compliance. All parts are REACH Unaffected or Vendor Undefined and carry EAR99 ECCN classification.

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

A: Electrical interchangeability is confirmed for all parts at the 500 Ohms ±1% specification level. Mechanical interchangeability requires verification of mounting space and lead configuration compatibility. The HS25 500R F is not interchangeable if the design requires 50W power handling.
