HSA50150RF Equivalent & Substitute Parts

Part Overview

The HSA50150RF is a 150 Ohms ±1% 50W wirewound chassis mount resistor manufactured by TE Connectivity Passive Product. This component is classified as Active product status and is designed for applications requiring precision resistive elements with high power dissipation capability. The resistor features aluminum housing with flanged mounting and solder lug termination, suitable for chassis-mounted installations in industrial and electronic equipment.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable, when inventory constraints exist, or when design requirements permit functional equivalents from different manufacturers. All substitute parts maintain the core electrical specifications of 150 Ohms resistance at ±1% tolerance with 50W power rating.

The identified substitute parts TMC050150R0FE02 (Vishay Dale) and UAL50-150RF8 (Riedon) satisfy all mandatory matching parameters and exceed the performance requirements for operating temperature range and temperature coefficient stability. Both substitutes maintain ROHS3 compliance and are classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: HSA50150RF

The HSA50150RF remains the primary specification when available. This part is manufactured by TE Connectivity Passive Product, carries Active product status, and maintains full ROHS3 compliance with REACH Unaffected designation. Current inventory availability is 1199 pieces.

Direct Substitute: TMC050150R0FE02 (Vishay Dale)

The TMC050150R0FE02 serves as a direct functional equivalent with enhanced performance characteristics. This substitute provides superior temperature coefficient stability (±20ppm/°C versus ±30ppm/°C) and extended operating temperature range (-55°C ~ 250°C versus -55°C ~ 200°C). The part is ROHS3 compliant and maintains Active product status. Physical dimensions are slightly reduced, with height-seated measurement of 0.625" compared to 0.669" for the primary part. Inventory availability is 941 pieces. This substitute is suitable for applications where the extended temperature range provides operational margin.

Upgrade Substitute: UAL50-150RF8 (Riedon)

The UAL50-150RF8 represents an enhanced substitute option with the broadest operating temperature range (-55°C ~ 275°C) and additional functional features including current sense capability, flame proof construction, pulse withstanding rating, and safety certification. Temperature coefficient performance matches the TMC050150R0FE02 at ±20ppm/°C. Physical dimensions are comparable to the TMC part, with height-seated measurement of 0.630". The part is ROHS3 compliant with REACH Unaffected status and carries Moisture Sensitivity Level 1 (Unlimited). Inventory availability is 1199 pieces. This substitute is appropriate for applications requiring enhanced thermal performance, safety certifications, or pulse withstanding capability.

All three parts maintain identical electrical core specifications (150 Ohms, ±1%, 50W) and are mechanically compatible with flanged chassis mount installations using solder lug termination.

Frequently Asked Questions (FAQ)

Q: Can TMC050150R0FE02 be used as a direct replacement for HSA50150RF?

A: Yes. The TMC050150R0FE02 meets all mandatory electrical and mechanical specifications: 150 Ohms ±1% 50W wirewound composition with flanged aluminum housing and solder lug termination. The substitute provides enhanced performance with superior temperature coefficient (±20ppm/°C) and extended operating range (-55°C ~ 250°C). Physical dimensions are slightly reduced but remain compatible with standard chassis mount installations.

Q: What is the primary difference between TMC050150R0FE02 and UAL50-150RF8?

A: Both substitutes match the core electrical specifications and exceed the HSA50150RF performance requirements. The UAL50-150RF8 provides the widest operating temperature range (-55°C ~ 275°C) and includes additional features: current sense capability, flame proof construction, pulse withstanding rating, and safety certification. The TMC050150R0FE02 offers a more compact form factor with moisture resistant coating. Selection depends on application-specific requirements for thermal range and functional features.

Q: Are there any physical compatibility concerns when substituting these parts?

A: Minor dimensional variations exist. The HSA50150RF measures 2.008" L x 1.181" W x 0.669" H (seated). The TMC050150R0FE02 measures 1.968" L x 1.140" W x 0.625" H (seated). The UAL50-150RF8 measures 1.969" L x 1.142" W x 0.630" H (seated). All parts use identical flanged mounting and solder lug termination. Verify mounting hole spacing and clearance in the target application, as the substitute parts are slightly smaller in all dimensions.

Q: Do all substitute parts maintain RoHS compliance?

A: Yes. The HSA50150RF, TMC050150R0FE02, and UAL50-150RF8 are all ROHS3 compliant. The HSA50150RF and UAL50-150RF8 carry REACH Unaffected status. The TMC050150R0FE02 lists REACH status as Vendor Undefined. All parts carry EAR99 ECCN classification and 8533.29.0000 HTSUS code.

Q: Which substitute should be selected for high-temperature applications?

A: The UAL50-150RF8 provides the highest operating temperature ceiling at -55°C ~ 275°C, compared to TMC050150R0FE02 at -55°C ~ 250°C and HSA50150RF at -55°C ~ 200°C. For applications requiring sustained operation above 200°C, the UAL50-150RF8 is the appropriate selection.

Q: What is the temperature coefficient significance in these parts?

A: Temperature coefficient measures resistance value drift with temperature change. The HSA50150RF specifies ±30ppm/°C, while both substitutes (TMC050150R0FE02 and UAL50-150RF8) provide superior stability at ±20ppm/°C. For precision applications requiring minimal resistance variation across temperature extremes, the substitute parts offer enhanced performance.

Q: Are packaging differences significant between these parts?

A: The HSA50150RF is supplied in Tray packaging, while both substitutes (TMC050150R0FE02 and UAL50-150RF8) are supplied in Bulk packaging. This distinction affects handling and storage procedures but does not impact electrical or mechanical performance. Verify packaging requirements for your procurement and inventory management processes.
