NHSA5030RJ Equivalent & Substitute Parts

Part Overview

The NHSA5030RJ is a 30 Ohms ±5% 50W wirewound chassis mount resistor manufactured by TE Connectivity Passive Product. This component is designed for high-power applications requiring reliable thermal dissipation through aluminum housing with flanged mounting. The part is Active status and ROHS3 compliant, with 899 pieces currently in stock.

Substitute parts become necessary when addressing specific application requirements such as improved tolerance specifications, extended operating temperature ranges, enhanced moisture resistance, or alternative packaging configurations while maintaining the core electrical and mechanical parameters of 30 Ohms resistance and 50W power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NHSA5030RJ is determined by the following core parameters that must remain constant across all equivalent and substitute parts:

Fixed Parameters (Must Match):

• Resistance value: 30 Ohms
• Power rating: 50W
• Composition: Wirewound
• Housing type: Aluminum
• Mounting feature: Flanges
• Lead style: Solder Lugs
• RoHS compliance: ROHS3 Compliant

Variable Parameters (Allowed to Differ):

• Tolerance: ±5% (main part) to ±1% (substitute parts) — tighter tolerance is acceptable
• Temperature coefficient: ±50ppm/°C to ±20ppm/°C — lower coefficient is acceptable
• Operating temperature range: -55°C ~ 200°C (main part) to -55°C ~ 275°C (substitute parts) — extended range is acceptable
• Packaging: Box/Axial to Tray or Bulk configurations
• Manufacturer: TE Connectivity, Vishay Dale, Stackpole Electronics, Riedon
• Physical dimensions: Minor variations within chassis mount standard envelope
• Additional features: Moisture resistance, current sense, flame proof, pulse withstanding capabilities

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance):

HSA5030RJ from TE Connectivity Passive Product is a direct parametric equivalent to NHSA5030RJ. Both parts share identical electrical specifications (30 Ohms ±5%, 50W, ±50ppm/°C) and mechanical characteristics. The primary difference is packaging configuration (Tray versus Box). HSA5030RJ is suitable for direct substitution when inventory of the NHSA5030RJ is unavailable. Both parts maintain Active product status and ROHS3 compliance.

Upgraded Tolerance Substitutes (±1% Tolerance):

TMC05030R00FE02 (Vishay Dale), KAL50FB30R0 (Stackpole Electronics), and UAL50-30RF8 (Riedon) are upgrade substitutes offering tighter tolerance specifications at ±1%. These parts are applicable in applications requiring improved accuracy over the standard ±5% tolerance of the main part. All three maintain 50W power rating, wirewound composition, aluminum housing, and flanged mounting.

TMC05030R00FE02 provides extended operating temperature to 250°C with ±20ppm/°C temperature coefficient and moisture-resistant features. KAL50FB30R0 extends operating temperature to 275°C with ±30ppm/°C temperature coefficient and moisture-resistant features. UAL50-30RF8 extends operating temperature to 275°C with ±20ppm/°C temperature coefficient and includes current sense, flame proof, pulse withstanding, and safety features.

All substitute parts are Active status and ROHS3 compliant. Selection among substitutes depends on specific application requirements for temperature range, temperature stability, and additional protective features.

Frequently Asked Questions (FAQ)

Q: Can HSA5030RJ replace NHSA5030RJ directly?

A: Yes. HSA5030RJ is a parametric equivalent with identical electrical and mechanical specifications. The only difference is packaging format (Tray versus Box). Direct substitution is valid for applications where packaging configuration does not impose constraints.

Q: What is the advantage of using TMC05030R00FE02, KAL50FB30R0, or UAL50-30RF8 over the main part?

A: These substitute parts offer ±1% tolerance compared to the ±5% tolerance of NHSA5030RJ. Additionally, they provide extended operating temperature ranges (250°C to 275°C versus 200°C) and improved temperature coefficients (±20ppm/°C to ±30ppm/°C versus ±50ppm/°C). Selection depends on application requirements for accuracy and thermal performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. NHSA5030RJ and all listed substitute parts (HSA5030RJ, TMC05030R00FE02, KAL50FB30R0, UAL50-30RF8) are ROHS3 compliant.

Q: What are the physical dimension differences between the main part and substitutes?

A: NHSA5030RJ measures 2.008" L x 1.181" W x 0.669" H (51.00mm x 30.00mm x 17.00mm). TMC05030R00FE02, KAL50FB30R0, and UAL50-30RF8 have slightly smaller dimensions ranging from 1.968" to 1.969" L x 1.140" to 1.142" W x 0.625" to 0.641" H. These variations remain within standard chassis mount resistor envelope specifications and do not affect mounting compatibility with flanged configurations.

Q: Which substitute part offers the highest operating temperature?

A: Both KAL50FB30R0 and UAL50-30RF8 support operating temperatures up to 275°C, compared to 250°C for TMC05030R00FE02 and 200°C for the main part NHSA5030RJ.

Q: What additional features does UAL50-30RF8 provide?

A: UAL50-30RF8 includes current sense, flame proof, pulse withstanding, and safety features in addition to the standard wirewound chassis mount resistor functionality. These features are beneficial for applications requiring enhanced protection and measurement capabilities.

Q: Can packaging format affect substitution decisions?

A: Yes. NHSA5030RJ is supplied in Box packaging, HSA5030RJ in Tray packaging, and TMC05030R00FE02, KAL50FB30R0, and UAL50-30RF8 in Bulk packaging. Packaging selection depends on assembly process requirements, inventory management, and handling procedures. All formats contain identical electrical and mechanical components.
