NHSA5016RF Equivalent & Substitute Parts

Part Overview

The NHSA5016RF is a 16 Ohms ±1% 50W wirewound chassis mount resistor manufactured by TE Connectivity Passive Product. This component is designed for high-power applications requiring precision resistance with stable thermal performance across extended operating ranges. The part is currently Active in product status with 823 units in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the core parameters: resistance value, tolerance, power rating, composition type, mounting configuration, and lead style. Alternative sources provide equivalent functional performance while offering variations in temperature coefficient, maximum operating temperature, and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the NHSA5016RF is determined by strict equivalence across the following core parameters:

Mandatory Equivalence Parameters:

Resistance value: 16 Ohms
Tolerance: ±1%
Power rating: 50W
Composition: Wirewound
Mounting feature: Flanges
Lead style: Solder Lugs
Housing material: Aluminum
Package configuration: Axial, Box

Variable Parameters (Allowed Differences):

Temperature coefficient (±50ppm/°C to ±20ppm/°C)
Maximum operating temperature (-55°C ~ 200°C to -55°C ~ 275°C)
RoHS compliance status
Moisture sensitivity level
Additional features (moisture resistant, flame proof, pulse withstanding)

Both identified substitute parts meet all mandatory equivalence criteria and are therefore direct functional replacements for the NHSA5016RF in applications where the core electrical and mechanical specifications are required.

Engineering Selection Recommendations

NHSA5016RF (TE Connectivity Passive Product)

The original part is Active in product status with established inventory availability. This part is suitable for applications where RoHS compliance is not a design requirement. The ±50ppm/°C temperature coefficient and -55°C ~ 200°C operating range define the baseline thermal stability for this specification class.

TMC05016R00FE02 (Vishay Dale)

This substitute is ROHS3 compliant and offers improved temperature coefficient performance at ±20ppm/°C with extended maximum operating temperature to 250°C. The Vishay Dale part includes moisture-resistant features and maintains dimensional compatibility with slightly reduced physical footprint. This part is Active in product status with 768 units in stock. Selection of this substitute is appropriate for applications requiring RoHS3 compliance and enhanced thermal stability.

UAL50-16RF8 (Riedon)

This substitute is ROHS3 compliant with the highest maximum operating temperature rating at 275°C and ±20ppm/°C temperature coefficient. The Riedon part includes additional safety features: current sense capability, flame proof construction, pulse withstanding rating, and safety certification. Moisture sensitivity level is rated at 1 (Unlimited). This part is Active in product status with 1092 units in stock. Selection of this substitute is appropriate for applications requiring extended thermal range, enhanced safety features, and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can TMC05016R00FE02 be used as a direct replacement for NHSA5016RF?

A: Yes. Both parts share identical resistance (16 Ohms), tolerance (±1%), power rating (50W), composition (wirewound), mounting configuration (flanges), lead style (solder lugs), and housing material (aluminum). The TMC05016R00FE02 offers improved temperature coefficient (±20ppm/°C versus ±50ppm/°C) and extended operating temperature range (-55°C ~ 250°C versus -55°C ~ 200°C). Physical dimensions are within acceptable tolerance for standard chassis mount applications.

Q: Can UAL50-16RF8 be used as a direct replacement for NHSA5016RF?

A: Yes. Both parts share identical resistance (16 Ohms), tolerance (±1%), power rating (50W), composition (wirewound), mounting configuration (flanges), lead style (solder lugs), and housing material (aluminum). The UAL50-16RF8 offers improved temperature coefficient (±20ppm/°C versus ±50ppm/°C), extended operating temperature range (-55°C ~ 275°C versus -55°C ~ 200°C), and additional safety features including flame proof construction and pulse withstanding capability. Physical dimensions are within acceptable tolerance for standard chassis mount applications.

Q: What are the dimensional differences between these parts?

A: The NHSA5016RF measures 2.008" L x 1.181" W x 0.669" H (51.00mm x 30.00mm x 17.00mm). The TMC05016R00FE02 measures 1.968" L x 1.140" W x 0.625" H (49.99mm x 28.96mm x 15.87mm). The UAL50-16RF8 measures 1.969" L x 1.142" W x 0.630" H (50.00mm x 29.00mm x 16.00mm). All three parts are mechanically compatible with standard chassis mount flanged resistor footprints. Verify PCB layout clearances for the original NHSA5016RF if substituting with the slightly smaller Vishay Dale or Riedon alternatives.

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

A: The NHSA5016RF has a temperature coefficient of ±50ppm/°C. Both the TMC05016R00FE02 and UAL50-16RF8 have improved temperature coefficients of ±20ppm/°C. Lower temperature coefficient values indicate better resistance stability across temperature variations, resulting in more precise performance in applications with significant thermal cycling.

Q: Are all three parts RoHS compliant?

A: The NHSA5016RF has RoHS status listed as Not Applicable. The TMC05016R00FE02 is ROHS3 compliant. The UAL50-16RF8 is ROHS3 compliant. If RoHS3 compliance is a design requirement, either the Vishay Dale or Riedon substitute must be selected.

Q: What is the maximum operating temperature for each part?

A: The NHSA5016RF operates from -55°C to 200°C. The TMC05016R00FE02 operates from -55°C to 250°C. The UAL50-16RF8 operates from -55°C to 275°C. Selection should be based on the thermal environment of the application. The Riedon part provides the widest operating range.

Q: What additional features does the UAL50-16RF8 provide?

A: The UAL50-16RF8 includes current sense capability, flame proof construction, pulse withstanding rating, and safety certification features. These features are not present in the NHSA5016RF or TMC05016R00FE02. Selection of the Riedon part is appropriate for safety-critical applications or those requiring enhanced transient protection.

Q: Are there inventory considerations for these substitutes?

A: The NHSA5016RF has 823 units in stock. The TMC05016R00FE02 has 768 units in stock. The UAL50-16RF8 has 1092 units in stock. All three parts are available in quantity for production applications.
