HS50 470R F Equivalent & Substitute Parts

Part Overview

The HS50 470R F is a 50-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 470 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 and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The HS25 470R F from ARCOL qualifies as a parametric equivalent based on the following matching criteria:

Matching Parameters:

• Resistance value: 470 Ohms (identical)
• Tolerance: ±1% (identical)
• Composition: Wirewound (identical)
• Temperature Coefficient: ±100ppm/°C (equivalent specification)
• Housing Type: Aluminum (identical)
• Mounting Feature: Flanges (identical)
• Lead Style: Solder Lugs (identical)
• RoHS Compliance: Yes (identical)
• MSL Rating: 1 (Unlimited) (identical)

Differing Parameter:

• Power Rating: 25W (reduced from 50W)

The HS25 470R F substitution is valid for applications where the thermal load does not exceed 25 watts continuous dissipation. The reduced power rating represents the primary design constraint for substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the HS50 470R F and HS25 470R F maintain active product status with full RoHS compliance and identical moisture sensitivity ratings. Selection between these components depends solely on application power dissipation requirements. The HS50 470R F is specified for applications requiring continuous power dissipation up to 50 watts. The HS25 470R F is suitable for applications with power dissipation not exceeding 25 watts. Both components feature identical electrical characteristics (resistance, tolerance, temperature coefficient) and mechanical mounting interfaces (flanges, solder lugs, height). The HS25 470R F exhibits a reduced physical length (27.30mm versus 49.10mm), which may provide space advantages in compact designs operating within the 25-watt thermal envelope.

Frequently Asked Questions (FAQ)

Q: Can the HS25 470R F replace the HS50 470R F in all applications?

A: No. The HS25 470R F is suitable only for applications where continuous power dissipation does not exceed 25 watts. Applications requiring 25 to 50 watts continuous dissipation must use the HS50 470R F or equivalent 50-watt rated component.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both components provide 470 ohms ±1% resistance with equivalent temperature coefficients (100ppm/°C and ±100ppm/°C respectively), wirewound composition, and identical lead styles (solder lugs).

Q: What are the physical dimension differences?

A: The HS50 470R F measures 49.10mm length, while the HS25 470R F measures 27.30mm length. Both maintain identical width (28.00mm) and seated height (14.80mm). The reduced length of the HS25 470R F may provide layout advantages in space-constrained designs.

Q: Are both parts RoHS compliant?

A: Yes. Both the HS50 470R F and HS25 470R F are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity).

Q: What mounting interfaces do these components use?

A: Both components feature aluminum housing with flanged mounting and solder lug lead termination, providing identical mechanical integration into chassis-mounted applications.
